Transcatheter arterial embolization for impending rupture of an isolated internal iliac artery aneurysm complicated with disseminated intravascular coagulation. (1/1212)

A 90-year-old male, with impending rupture of an isolated internal iliac artery aneurysm (IIAA) complicated with disseminated intravascular coagulation (DIC) was successfully treated with transcatheter arterial embolization (TAE). After TAE, enlargement of the aneurysm was arrested and coagulation-fibrinolytic abnormalities induced by DIC improved without severe complications. Although IIAA is relatively rare, the post-operative mortality of patients with ruptures is reportedly high. We assessed the usefulness of this procedure for impending rupture of IIAA, especially for patients in high risk groups.  (+info)

Anomalous origin of the left coronary artery from the pulmonary artery: natural history and normal pregnancies. (2/1212)

Two female patients are described with anomalous origin of the left coronary artery arising from the pulmonary artery who sustained an anterolateral myocardial infarction in infancy. Neither patient received surgical treatment although both have lived to middle age with minimal cardiovascular problems and have had uncomplicated pregnancies. Good exercise tolerance and long term survival may be possible even without surgery for patients with this anomaly.  (+info)

Intimal tear without hematoma: an important variant of aortic dissection that can elude current imaging techniques. (3/1212)

BACKGROUND: The modern imaging techniques of transesophageal echocardiography, CT, and MRI are reported to have up to 100% sensitivity in detecting the classic class of aortic dissection; however, anecdotal reports of patient deaths from a missed diagnosis of subtle classes of variants are increasingly being noted. METHODS AND RESULTS: In a series of 181 consecutive patients who had ascending or aortic arch repairs, 9 patients (5%) had subtle aortic dissection not diagnosed preoperatively. All preoperative studies in patients with missed aortic dissection were reviewed in detail. All 9 patients (2 with Marfan syndrome, 1 with Takayasu's disease) with undiagnosed aortic dissection had undergone >/=3 imaging techniques, with the finding of ascending aortic dilatation (4.7 to 9 cm) in all 9 and significant aortic valve regurgitation in 7. In 6 patients, an eccentric ascending aortic bulge was present but not diagnostic of aortic dissection on aortography. At operation, aortic dissection tears were limited in extent and involved the intima without extensive undermining of the intima or an intimal "flap." Eight had composite valve grafts inserted, and all survived. Of the larger series of 181 patients, 98% (179 of 181) were 30-day survivors. CONCLUSIONS: In patients with suspected aortic dissection not proven by modern noninvasive imaging techniques, further study should be performed, including multiple views of the ascending aorta by aortography. If patients have an ascending aneurysm, particularly if eccentric on aortography and associated with aortic valve regurgitation, an urgent surgical repair should be considered, with excellent results expected.  (+info)

Follow-up results of transvenous occlusion of patent ductus arteriosus with the buttoned device. (4/1212)

OBJECTIVES: The purpose of this presentation is to document results of buttoned device (BD) occlusion of patent ductus arteriosus (PDA) in a large number of patients with particular emphasis on long-term follow-up in an attempt to provide evidence for feasibility, safety and effectiveness of this method of PDA closure. BACKGROUND: Immediate and short-term results of BD occlusion of PDA have been documented in a limited number of children. METHODS: During a six-year period ending August 1996, transcatheter BD closure of PDA was attempted in 284 patients, ages 0.3 to 92 years (median 7) under a protocol approved by the local institutional review boards and FDA with an investigational device exemption in U.S. cases. RESULTS: The PDAs measured 1 to 15 mm (median 4) at the narrowest diameter; 20 were larger than 8 mm and 10 larger than 10 mm. They were occluded with devices measuring from 15 to 35 mm delivered via 7F (N = 140) or 8F (N = 144) sheaths. Successful implantation of the device was accomplished in 278 (98%) of 284 patients. The Qp:Qs decreased from 1.8+/-0.6 (mean+/-SD) to 1.09+/-0.19 (p < 0.001). Effective occlusion defined as no (N = 167 [60%]) or trivial (N = 79 [28%]) residual shunt was achieved in 246 (88%) patients. All types of PDAs, irrespective of the shape (conical, tubular or short), size (small or large) or length (short or long) of the PDA and previously implanted Rashkind devices, could be occluded. Follow-up data, 1 to 60 months (median 24) after device implantation, were available in 234 (84%) patients. Seven (3%) patients required reintervention to treat residual shunt with (N = 2) or without (N = 5) hemolysis. Actuarial reintervention-free rates were 95% at 1 and 5 years. There was gradual reduction of actuarial residual shunts and were 40%, 28%, 21%, 14%, 11%, 10%, 6% and 0% respectively at 1 day, 1, 6, 12, 24, 36, 48 and 60 months after device implantation. Incorporation of folding plug over the button loop in 10 additional patients produced immediate and complete occlusion of PDA. CONCLUSIONS: This large multiinstitutional experience confirms the feasibility, safety and effectiveness of buttoned device closure of PDAs. All types of PDAs irrespective of the shape, length and diameter can be effectively occluded. Incorporation of folding plug over the button loop produces complete PDA occlusion at the time of device implantation.  (+info)

The snare-assisted technique for transcatheter coil occlusion of moderate to large patent ductus arteriosus: immediate and intermediate results. (5/1212)

OBJECTIVES: The purpose of this study was to evaluate the feasibility, safety and efficacy of using a snare-assisted technique to coil occlude the moderate to large size patent ductus arteriosus (PDA). BACKGROUND: Transcatheter occlusion of small PDAs using Gianturco coils is safe and effective. However, in larger size PDAs and/or those with short PDA length, the procedure still carries risks of coil embolization, incomplete occlusion and failure to implant the coil. METHODS: From January 1994 to June 1997, the records of 104 consecutive snare-assisted coil occlusions of moderate to large PDAs (minimum diameter >2.0 mm) were reviewed. Immediate and intermediate outcomes including complete and partial occlusion, failure to implant and complications were analyzed with respect to ductal type and size. RESULTS: Patient age ranged from 0.1 to 70.1 years (median 3.3 years). Minimum PDA diameter ranged from 2.1 to 6.8 mm (mean 3.0 +/- 0.9 mm). Angiographic types were A-62, B-13, C-6, D-14 and E-9. Using the snare-assisted technique, coil placement was successful in 104/104 patients (100%), irrespective of size or angiographic type. Immediate complete closure was observed in 73/104 (70.2%) and was related to smaller PDA size, but not to angiographic type. Complete closure was documented in 102/104 (98.1%) at 2- to 16-month follow-up. Successful closure was unrelated to PDA size or type. Coil embolization to the pulmonary artery occurred in 3/104 (2.9%) patients and was not related to PDA size or type. The need for multiple coils was found in 28/104 patients (26.9%), and was related to larger PDA size, but not to angiographic type. CONCLUSIONS: The snare-assisted delivery technique allows successful occlusion of moderate to large PDAs up to 6.8 mm, irrespective of angiographic type. This technique permits improved control and accuracy of coil placement, and facilitates delivery of multiple coils.  (+info)

Surgical renal artery reconstruction without contrast arteriography: the role of clinical profiling and magnetic resonance angiography. (6/1212)

PURPOSE: Contrast arteriography is the accepted gold standard for diagnosis and treatment planning in patients with atherosclerotic renovascular disease (RVD). In this study, the results of a selective policy of surgical renal artery reconstruction (RAR) with magnetic resonance angiography (MRA) as the sole preoperative imaging modality are reviewed. METHODS: From May 1993 to May 1998, 25 patients underwent RAR after clinical evaluation, and aortic/renal MRA performed with a gadolinium-enhanced and 3-dimensional phase contrast technique. Clinical presentations suggested severe RVD in all patients and included poorly controlled hypertension (16 patients), hospitalization for hypertensive crises and/or acute pulmonary edema (13), and deterioration of renal function within one year of operation (15). Thirteen patients had associated aortic pathologic conditions (12 aneurysms, 1 aortoiliac occlusive disease), and eight of these patients also underwent noncontrast computed tomography scans. Significant renal dysfunction (serum creatinine level, >/=2.0 mg/dL) was present in all but 4 patients with 14 of 25 patients having extreme (creatinine level, >/=3.0 mg/dL) dysfunction. RESULTS: Hemodynamically significant RVD in the main renal artery was verified at operation in 37 of 38 reconstructed main renal arteries (24/25 patients). A single accessory renal artery was missed by MRA. RAR was comprehensive (bilateral or unilateral to a single-functioning kidney) in 21 of 25 patients and consisted of hepatorenal bypass graft (3 patients), combined aortic and RAR (13 patients), isolated transaortic endarterectomy (8 patients), and aortorenal bypass graft (1 patient). Early improvement in both hypertension control and/or renal function was noted in 21 of 25 patients without operative deaths or postoperative renal failure. Sustained favorable functional results at follow-up, ranging from 5 months to 4 years, were noted in 19 of 25 patients. CONCLUSION: MRA is an adequate preoperative imaging modality in selected patients before RAR. This strategy is best applied in circumstances where the clinical presentation suggests hemodynamically significant bilateral RVD and/or in patients at substantial risk of complications from contrast angiography.  (+info)

Periprosthetic leak and rupture after endovascular repair of abdominal aortic aneurysm: the significance of device design for long-term results. (7/1212)

We present a case of abdominal aortic aneurysm treated with an endovascular bifurcated aortic graft in which a periprosthetic leak caused by a tear in the polyester prosthesis appeared between 9 and 12 months after surgery. The tear appeared adjacent to a suture breakage that caused separation of two struts of the nitinol wire framework in the body of the stent graft. The leak was sealed with insertion of a new endovascular tube graft into the body of the bifurcation. Eight months later, the patient had a nonfatal rupture of the abdominal aortic aneurysm because detachment of the second limb from the bifurcation caused a new major periprosthetic leak. According to the manufacturer of this device, suture breakage with separation of metal components is commonly seen, but perforation of the polyester prosthesis caused by movement of the metal stent against the fabric has not been reported. It is likely that this occurred in our patient. Detachment of the second limb from the bifurcated stent, causing a rupture, has been described before. Increasing angulation and tortuosity of the stent graft, as a result of either remodeling of the sac or elongation of the stent, and reduced compliance to angulation after the stent-in-stent procedure might have contributed to the detachment in this case.  (+info)

Realistic expectations for patients with stent-graft treatment of abdominal aortic aneurysms. Results of a European multicentre registry. (8/1212)

OBJECTIVE: the outcomes for patients after endovascular treatment of abdominal aortic aneurysm (AAA) are determined primarily by the endpoints of death and endoleaks, the latter representing continued risk of rupture. The data of a multicentre registry were analysed with regard to the early outcome of stent-graft procedures for AAA and the complications associated with this treatment. In addition, the results during follow-up were analysed by determining mortality and endoleak development as separate endpoints and as a combined endpoint defined as endoleak-free survival. SETTING: 38 European institutions of Vascular Surgery collaborating in a multicentre registry project. PATIENTS AND METHODS: 899 patients with AAA underwent between May 1994 and March 1998 elective endovascular repair (818 men and 81 women; mean age 69 years). 80 (8.9%) of the patients had medical conditions that excluded them from open repair. 818 (91%) of patients had a bifurcated device, 63 (7%) had a straight tube graft, and only 18 (2%) had an aorto-uni-iliac device. Clinical examination and contrast-enhanced computed tomography was performed at fixed follow-up intervals to assess increase or decrease of the maximum transverse diameter (MTD). Endoleaks observed at follow-up were discriminated into persistent endoleak and temporary endoleak. The latter is defined as single time observed endoleaks or with two or more negative imaging studies between observed endoleaks. Life-table analyses were used to calculate the rates of freedom-from-endoleak (no endoleak at any time), freedom-from-persistent endoleak (no persistent endoleak), patient survival, and persistent-endoleak-free-survival. RESULTS: the median follow-up of this patient series was 6.2 months. The ratio between observed and expected follow-up data was 82% for the overall follow-up period. However, at 18 months of follow-up this rate was only 45%. The number of patients followed during this period was sufficient to allow statistically meaningful assessment. The MTD in patients with temporary endoleaks demonstrated a significant decrease at 6 to 12 months compared to preoperative values (mean 57 and 53 respectively, p =0.004). In patients with persistent endoleaks there was no change between the preoperative and 6-month MTD (mean 57 and 60 mm respectively). At 6 and 18 months freedom-from-endoleak was 83% and 74% and freedom-from-persistent endoleak was 93% and 90%, respectively. The 18-month cumulative patient survival was 88% and the main outcome measure, the persistent endoleak-free-survival was 79%. CONCLUSIONS: the MTD decreases in patients with temporary endoleak, but not in patients with persistent endoleak. Therefore, the use of the rate of freedom-from-persistent endoleak, reflecting absence of persisting endoleaks to estimate the prognosis with regard to the AAA, is justified. Determining persistent endoleak-free survival appears a rational approach to provide a realistic outlook for patients with stent-grafted AAA. The observed 18-month endoleak-free survival reflects a satisfactory mid-term result.  (+info)

The CX Aortic Edited Cases session yesterday provided the unique opportunity for the audience to interact with experts and ask questions about the cases being presented. The first session focused on thoracic aortic cases and the remainder were abdominal aortic cases.. Michael Dake (Stanford, USA) presented a case with the TAG thoracic branch endoprosthesis (Gore) which is part of a US feasibility multicentre trial that has evaluated 22 patients (mean age 74.1±10.5 years, 54.5% male) undergoing branched thoracic endovascular aortic repair (B-TEVAR) in Ishimaru zone 2.. According to Dake, the endograft features a single side branch designed to facilitate aortic coverage proximal to the left subclavian artery, while maintaining branch vessel patency. Pathology treated included fusiform (n=10) or saccular (n=12) aneurysm, with a mean aortic diameter of 5.7±1.1cm.. Reporting on the progress of the trial, he said that the primary endpoints of device delivery and branch vessel patency was achieved in ...
An improved stent design and stent delivery catheter assembly for repairing a main vessel and a side branch vessel forming a bifurcation. The stent includes rings aligned along a common longitudinal axis and connected by links, where the stent has one or more portals for aligning with and partially expanding into the opening to the side branch vessel. The stent is implanted at a bifurcation so that the main stent section is in the main vessel, and the portal section covers at least a portion of the opening to the side branch vessel. A second stent can be implanted in the side branch vessel and abut the expanded central section to provide full coverage of the bifurcated area in the main vessel and the side branch vessel. Radiopaque markers on the stent and on the tip of the delivery catheter assist in aligning the portal section with the opening to the side branch vessel.
The catheter assembly includes an expandable member mounted to the distal end of a placement catheter, for delivery of a therapeutic device in one of the branch vessels of a bifurcated vessel. The catheter assembly includes lumens for a tracking guide wire and a positioning guide member for placement of the therapeutic device. The therapeutic device is mounted on the expandable member, the tracking guide wire is placed into the target branch vessel, and the placement catheter is then introduced over the tracking guide wire. A positioning guide member is introduced through the catheter, extended through an exit port in the catheter proximal to the expandable member, and then placed in another branch vessel of the bifurcation. The placement catheter then is advanced until the positioning guide member engages the vessel carina between the branch vessels, and the therapeutic device then may be placed accurately in the target branch vessel. In another form of the catheter assembly, a secondary catheter

AU - Lin, Fang Yue. AU - Chu, Shu Hsun. PY - 2005/1/1. Y1 - 2005/1/1. N2 - Background. Optimal treatment of acute type B aortic dissection remain unclear. The aim of this study was to assess the clinical outcome of acute type B aortic dissection. Methods. In the last 8 years, 107 patients were admitted for acute type B aortic dissection. We medically treated patients at the time of onset with antihypertensives. Surgery was considered if there is intractable pain, uncontrolled hypertension, severe aortic branch malperfusion, or aneurysm expansion. Results. Twenty-nine patients had pleural effusion (27%), 9 patients had leg ischemia (8%), 5 patients had impending rupture, and 2 patients had aneurysm enlargement exceeding 60 mm on repeated imaging studies. A total of 16 patients (15%) underwent surgical ...

Current management and outcome of chronic type B aortic dissection: results with open and endovascular repair since the advent of thoracic endografting
Aortic dissection, though rare, is an often fatal event.1 A recent population-based study from Oxford showed that women have higher mortality from aortic dissection and are more likely to die before hospital assessment,2 which was also shown by the worlds largest registry of aortic dissection.3 Importantly, most individuals with aortic dissection had inadequately controlled hypertension, suggesting that modifiable risk factors may play a role in prevention.2 Moreover, women have worse outcomes following surgery for aortic dissection,3 and the surgical risk is even higher during pregnancy.4 ,5 The majority of aortic dissections in women of childbearing age occur during pregnancy and have adverse consequences for the mother and the fetus.6 Data from the Swedish National Birth Registry in women ,40 years of age have shown that pregnancy is associated with a 25-fold increased risk of aortic dissection.6 The scientific literature regarding aortic dissection and pregnancy is largely made up of case ...

Greenhalgh spoke to the audience about innovations and challenges to innovation in collecting data. He presented insights from the European Vascular and Endovascular Monitor, a consumption-based monitor covering 200 centres from Western Europe. He said that the advantage of a monitor approach was that it was enduring and effective in rapidly-shifting markets.. From the thoracic market, data showed that thoracic endovascular aneurysm repair remains the "gold standard" and that the current issues in the thoracic field were the size of the aneurysm, and the perceived need for a screening programme. For carotid procedures, Greenhalgh said the data indicated open surgery as the gold standard and that endovascular procedures were focused in the German and Italian markets.. "Endovascular procedures continue to grow at the expense of open surgery," Greenhalgh commented on aortic-iliac procedures and femoropopliteal, with the use of drug-eluting balloons on the increase in the latter. Hefsyv identified ...

A series of studies of f-electron systems based on density functional theory methods have been performed. The focus of the studies has been on magnetic and structural properties, as well as investigating ways to handle strong electron correlation in these systems.. A version of the self-interaction correction (SIC) method has been developed for a full-potential linear muffin-tin orbital method. The method is demonstrated to have the strong capabilities of previous SIC implementations, to study energetics and phase stabilities of d- and f-electron systems with localisation-delocalisation transitions, but with no geometrical constraints from the underlying band structure method. The method is applied to the high-TC superconductor CeOFeAs, in which the f-shell of the Ce atoms is argued to undergo a Mott transition to a delocalised state under pressure.. The non-collinear magnetic structures of two rare earth compounds, TbNi5 and CeRhIn5 have been studied, and in both cases the complex magnetic ...

In this study, we provide a contemporary overview of clinical outcomes in patients with known MFS without prior aortic dissection. This represents one of the largest MFS studies to date using 3-dimensional imaging techniques. We found a type B aortic dissection rate of 9% during a median follow-up period of 6 years. Type B aortic dissections generally occurred in mildly dilated proximal descending aortas, especially in patients with prior prophylactic aortic surgery. From our data, we were able to develop a risk score to predict type B aortic dissection in patients with MFS, on the basis of history of prophylactic aortic root surgery and proximal descending aortic diameter.. The occurrence of type A aortic dissection has become a rare event in patients with known MFS in the era of aggressive prophylactic surgery. Although AoRR has improved life expectancy considerably, distal aortic disease may develop later in patients with MFS (14,15). Replacement of the aortic root or ascending aorta with a ...

We studied the use of carbon dioxide (CO 2) as a non-nephrotoxic contrast agent for EVAR. Methods: Recorded data from 114 consecutive patients who underwent EVAR with CO 2 as the contrast agent over 44 months were retrospectively analyzed. CO 2 was used exclusively in 72 patients and in an additional 42 patients iodinated contrast (IC) was given (mean, 37 mL). Renal and hypogastric artery localization and completion angiography were done with CO 2 in all patients, including additional arterial embolization in 16 cases. ...

Introduction: Endovascular aneurysm repair (EVAR) has been an established treatment for abdominal aortic aneurysm (AAA). Although statin use has been shown associated with better long-term survival following open AAA surgery, its impact on EVAR has not been systematically explored.. Methods: We retrospectively analyzed a multicenter database of 368 consecutive patients (age, 76 ± 8 years; 84% male) undergoing EVAR for AAA between November 2006 and December 2013. The outcome measure was overall survival following EVAR. Independent predictor associated with the outcome was assessed by Cox proportional hazard regression model. Furthermore, the association between the statin use and the outcome was assessed.. Results: During the follow-up of 30 ± 20 months, 38 patients died from cardiovascular disease (33%), cancer (23%) or infection (23%). Survival rate was 96% and 81% at 1 and 5 years, respectively. In Cox regression analysis, statin use (in 213 AAA patients, 58%) was negatively associated with ...
BACKGROUND: Aortic dissection is a separation of the aortic wall, caused by blood flowing through a tear in the inner layer of the aorta. Aortic dissection is an infrequent but life-threatening condition. The incidence of aortic dissection is 3 to 6 per 10,000 per year in the Western population, and can be up to 43 per 10,000 per year in the Eastern population. Over 20% of people with an aortic dissection do not reach a hospital alive. After admission, the mortality rates for people with an aortic dissection are between 10% and 20% for those who received endovascular treatment, and between 20% and 30% for those who had open surgery. Thoracic endovascular aortic repair (TEVAR) is the standard endovascular method to treat complicated type B aortic dissection (aortic dissections without involvement of the ascending aorta). Although TEVAR is less invasive than open surgery and has a better long-term aortic remodeling effect than conservative medical treatment, favourable aortic remodelling is ...

OBJECTIVE This study reports the early and midterm to long-term experience of chimney grafts (CGs) in urgent endovascular repair of complex lesions in the thoracic aorta. METHODS Twenty-nine high-risk patients (20 men) who were unfit for open repair were treated using CG technique for ruptured (n = 14) or symptomatic (n = 15) aortic lesions engaging the aortic arch itself (n = 9), the descending aorta (n = 10), or the thoracoabdominal aorta (n = 10). Twenty-two patients (76%) were treated urgently (≤24 hours) and seven were semiurgent (≤3 days). Of 41 chimneys used, 24 were placed in supra-aortic branches and 17 in visceral branches. Median follow-up (interquartile range) for the entire cohort was 2 years (0.6-3.8 years), 2.5 years (1-4 years) for 30-day survivors, and 3.5 years (1.9-6.4 years) for those who were still alive. RESULTS Four patients (14%) died ≤30 days of cerebral infarction (n = 1), visceral ischemia secondary to the initial rupture (n = 1), multiple organ failure (n = 1), or
Prior to endograft deployment, the position of all arch branches was ascertained by arteriography using a pigtail catheter inserted from left femoral arterial access. The endograft was then deployed, but it remained partially constrained because of the DLTs. Partial constraint of the endograft and traction towards the inner aortic curvature (using ETAG) were necessary to leave space for the cannulation of fenestrations from the side of the outer aortic arch curvature. The IA and LCCA fenestrations were cannulated (the LSA had been pre-cannulated) and covered stents positioned within all three and kept ready for deployment: BeGraft 14 × 38 mm (Bentley InnoMed GmbH, Lotzenäcker 25, 72379 Hechingen, Germany) via 12 Fr/45 cm guiding sheath (Flexor Ansel, COOK Medical, Bloomington, IN 47402-4195 USA) in the IA, Advanta 12 × 29 mm (Getinge, 40 Continental Blvd, Merrimack, NH 03054, USA) via 9 Fr/45 cm guiding sheath (Flexor Ansel, COOK Medical) in the LSA and BeGraft 7 × 38 mm via 7 Fr/90 cm ...

different portions of the stent/stent graft 10 are heat set at different diameters. For example, a braided material could be fabricated on a mandrel having a first larger diameter (e.g., 30-35 mm), which is generally the maximum diameter to which the stent/stent graft would be capable of expanding. The braided material may then be pulled down or compressed onto a mandrel having a second smaller diameter (e.g., 20-25 mm) and heat set such that the heat set stent/stent graft is capable of self-expanding to the diameter of the second smaller diameter. However, when the stent/stent graft 10 is axially compressed, the stent/stent graft is capable of expanding to the first larger diameter. Thus, in order to deploy the stent/stent graft 10, the distal end 34 of the stent/stent graft 10 may be positioned distally of the aneurysm 14 and as the delivery catheter 38 is retracted, the distal end of the stent/stent graft engages the lumen 12. As the stent/stent graft is further deployed in the region of an ...
Endovascular aortic aneurysm repair (EVAR) is a surgical operation for patients suffering from aorta inflation known as aorta aneurysm. EVAR carries significantly lower preoperative risk than open repair surgery; therefore, it is preferred by patients and recommended by medical guidelines as the choice for treating abdominal aortic aneurysm AAA [1]. There is an obligatory need for lifelong surveillance after this operation and it is considered to be expensive, varied, and poorly-calibrated [2]. However, the surveillance procedures are extensively various [3] and there is shortage of an indication to select the best timing or modality; Patients may be exposed to radiations and contrast nephropathy as a result of frequent surveillance. However, for some patients, complications required for treatment might be missed between surveillance [4-6]. For that reason, optimizing surveillance is very important [7, 8]. It is considered as an important issue in clinics and affects the long-standing ...
Renal insufficiency is a risk factor for mortality and morbidity during endovascular aneurysm repair. Multiple changes in practice have occurred to mitigate renal injury and renal dysfunction. Transrenal fixation does carry an increased risk of a decline in renal function in the medium term. Renal stenting for athero-occlusive disease during endovascular aneurysm repair needs careful consideration, as indications have changed and there are unexpected consequences with early vessel occlusion. The growing number of renal interventions during complex endovascular aneurysm repair with the advent of chimney snorkel/periscope techniques and the introduction of fenestrated grafts has shown the resilience of the intervention with relatively low renal issues (approximately 10%), but has also illustrated the need for additional device development ...
BACKGROUND: The chimney technique has been successfully used to treat juxtarenal aortic aneurysms. The two main issues with this technique are gutter formation and chimney graft (CG) compression, which induce a risk for type Ia endoleaks and stent thrombosis, respectively. In this benchtop study, the geometry and renal artery flow of chimney endovascular aneurysm repair configurations were compared with chimney configurations with endovascular aneurysm sealing (ch-EVAS). METHODS: Seven flow phantoms were constructed, including one control and six chimney endovascular aneurysm repairs (Endurant [Medtronic Inc, Minneapolis, Minn] and AFX [Endologix Inc, Irvine, Calif]) or ch-EVAS (Nellix, Endologix) configurations, combined with either balloon-expandable or self-expanding CGs with an intended higher positioning of the right CG in comparison to the left CG ...
In recent years, in parallel with the increase of endovascular aortic repair (EVAR) procedures performances, a rise of late open surgical removal of EVAR implants has been observed, due to non-endovascularly correctable graft complications. Among them endograft infection is a rare but devastating occurrence, accounting for an incidence ranging from 0.2% to 0.7% in major series, and almost 1% of all causes of endograft explantations. However, a real estimation of the incidence of the problem respect to the number of EVAR implantations is difficult to obtain. Time to infection is usually defined as the period between EVAR and presentation of symptoms that leads to the infection diagnosis. It can be extremely variable, depending on bacterial virulence and host conditions. The diagnosis of an endograft infection is usually based on a combination of clinical symptoms, imaging studies and microbial cultures whenever possible. If computed tomography (CT) scan is employed in almost 100% of infection ...
Type B aortic dissection (AoD) is a disease connected to high blood load on the aortic wall and to a reduced aortic wall resistance. Nowadays, prognosis on type B AoD results to be particularly difficult with an high incidence of patients treated with medical therapy which manifest complication connected with dissection and which should have been treated with surgical repair immediately. This work aims to study those haemodynamical and morphological proprieties of dissected aorta, which can influence the progression or stability of type B AoD. Computational fluid-dynamic analyses were performed on twenty-five patients with type B AoD, whose nine presented an aneurysm evolution and sixteen presented no further complication connected with dissection. Blood flow features showed that the true lumen flow was laminar and uniform while false lumen flow was less homogeneous with a consequent recirculating path. We found that entry point zone proximal to the aortic arch showed both high blood velocity ...

When the decision to intervene is made, one of the most important factors to consider is the proximal extent of the repair, Modarai noted, and added, "We know from the literature that almost half of all repairs will be in zone 2; dissection patients are younger than those with aneurysmal disease and tend to have less favourable arch morphology; and our data suggest that around 16% of cases will have a retrograde extension into the arch. According to the IRAD data, the latter does not impact adverse outcomes but all of these factors are important considerations for making the decision whether to intervene or not and how safe that intervention is likely to be, particularly in uncomplicated cases.". Unfavourable arch anatomy is associated with increased risk. It demands a longer sealing zone, and tortuosity and high angulation make deployment more challenging. "The characteristics of the graft and the reliability with which we deploy it are of paramount importance. Particular attention should be ...

I am 60 years old. When I was 54 I had a bypass surgery for coronary triple vessel disease. After 2 years, I had a severe leg pain and underwent an aortography which detected 80% block in the arteries in lower limb and consequently inserted 4 stents in the hip junction and in femoral arteries in both legs. All the treatment was taken at Madras Medical Mission. Since then it was ok for some time regarding arterial blocks in the lower limbs, but of late I am experiencing the pain while walking. I am currently taking simvotin 10mg, ASA 50mg, for artery problems and became a type II diabetic since 1998 and taking amaril 1mg and glycomet 500mg, and lastly asomex AT for high blood pressure for the last 6 months.

The suitable treatment strategy for acute descending aortic dissection has long been a matter of debate and continues to be a challenge [1]. High mortality rates in surgical treatment (25-50%) of complicated acute type B dissections, directed surgeons to search for other treatment modalities. Implementation of endovascular techniques has provided new therapeutic options [5]. Initial series and subsequent multicenter trials demonstrated technical feasibility and a low rate of complications even in high-risk patients with acute type B dissection.. However, treatment of acute aortic dissections by endovascular grafting itself carries some risks. Leakage can occur in approximately 25% of patients. Rarely, the stent graft may not plug the aortic wall adequate and may dislocate. In 8% of patients embolic material may originate from an atherosclerotic basis and corrupt the blood flow of the spinal cord, leading to paraplegia. There is furthermore the risk for abdominal malperfusion. In this situation ...

The study, conducted by researchers from the University of Massachusetts Memorial Medical Centers division of vascular and endovascular surgery in Worcester, examined the national frequency, predictors, outcomes, and the effect of institutional volume metrics in cases where endovascular aortic repair (EVAR) was used to repair ruptured abdominal aortic aneurysms (RAAAs) between 2001 and 2006.. Over the years EVAR has gained wide acceptance for the elective treatment of abdominal aortic aneurysms (AAA). This success has led to increased interest in similar treatment of RAAAs, because most patients who suffer a RAAA do not survive long enough to obtain medical care. The mortality rate for patients who do survive and undergo traditional open surgical repair ...
The authors concluded that endovascular technology could be helpful in treating selected young patients with genetically triggered thoracic aortic disease. However, we should be caution evaluating results of this mid-term follow-up study. Most aortic surgeons support the idea of endovascular therapy of genetically triggered aortic disease, but only in case of already prosthetic replaced aortic segments corresponding to proximal and distal landing zones. Endovascular treatment of the native aorta in Marfan and Loeys-Dietz syndrome patients is not recommended due to high-risk of later endoleaks type I. Further research and long-term follow-up studies are necessary to identify patients with genetically triggered thoracic aortic disease who benefit from endovascular aortic repair and delineate contraindication for endovascular approach.. ...

... (CTLM) is the trademark of Imaging Diagnostic Systems, Inc. (IDSI, United States) for its optical tomographic technique for female breast imaging. This medical imaging technique uses laser energy in the near infrared region of the spectrum, to detect angiogenesis in the breast tissue. It is optical molecular imaging for hemoglobin both oxygenated and deoxygenated. The technology uses laser in the same way computed tomography uses X-Rays, these beams travel through tissue and suffer attenuation. A laser detector measures the intensity drop and the data is collected as the laser detector moves across the breast creating a tomography image. CTLM images show hemoglobin distribution in a tissue and can detect areas of Angiogenesis surrounding malignant tumors, that stimulate this angiogenesis to obtain nutrients for growth. ...
... is a medical technique for visualizing the interior of blood vessels. In this technique, a flexible fiberoptic catheter inserted directly into an artery.[1] It can be helpful in diagnosing e.g. arterial embolism.[1] Angioscopy is also used as an adjunctive procedure during vascular bypass to visualize valves within venous conduits. The instrument used to perform angioscopy is called as angioscope. Coronary artery angioscopy, which first was used to reveal the presence of a blood clot in the coronary arteries of patients with unstable angina and myocardial infarction,[2] is now widely used in catherization laboratories to visualize stents. ...
... or hepatobiliary scintigraphy is scintigraphy of the hepatobiliary tract, including the gallbladder and bile ducts. The image produced by this type of medical imaging, called a cholescintigram, is also known by other names depending on which radiotracer is used, such as HIDA scan, PIPIDA scan, DISIDA scan, or BrIDA scan. Cholescintigraphic scanning is a nuclear medicine procedure to evaluate the health and function of the gallbladder and biliary system. A radioactive tracer is injected through any accessible vein and then allowed to circulate to the liver, where it is excreted into the bile ducts and stored by the gallbladder[1] until released into the duodenum. In the absence of gallbladder disease, the gallbladder is visualized within 1 hour of the injection of the radioactive tracer. If the gallbladder is not visualized within 4 hours after the injection, this indicates either cholecystitis or cystic duct obstruction, such as by cholelithiasis (gallstone formation).[2] This ...
The procedure involves the insertion of a Foley catheter into the distal urethra and minimally inflating it. This is followed by instillation of 30mL of water-soluble contrast and a plain radiograph is obtained; leakage of the contrast suggests urethral injury (usually secondary to pelvic trauma) and is an indication for surgical intervention. It is used when there is suspicion of urethral trauma, such as a history of trauma to the area followed by pain, inability to void urine, or the presence of blood at the urethral meatus, a scrotal hematoma, or free-floating prostate on rectal examination. If a urethral injury is suspected, a retrograde urethrogram should be performed before attempting to place a Foley catheter into the bladder. If there is a urethral disruption, a suprapubic catheter should be placed. ...
Four types of confocal microscopes are commercially available: Confocal laser scanning microscopes use multiple mirrors (typically 2 or 3 scanning linearly along the x and the y axis) to scan the laser across the sample and "descan" the image across a fixed pinhole and detector.. Spinning-disk (Nipkow disk) confocal microscopes use a series of moving pinholes on a disc to scan spots of light. Since a series of pinholes scans an area in parallel each pinhole is allowed to hover over a specific area for a longer amount of time thereby reducing the excitation energy needed to illuminate a sample when compared to laser scanning microscopes. Decreased excitation energy reduces photo-toxicity and photo-bleaching of a sample often making it the preferred system for imaging live cells or organisms.. Microlens enhanced or dual spinning disk confocal microscopes work under the same principles as spinning-disk confocal microscopes except a second spinning disk containing micro-lenses is placed before the ...
An upper gastrointestinal series, also called an upper gastrointestinal study or contrast radiography of the upper gastrointestinal tract, is a series of radiographs used to examine the gastrointestinal tract for abnormalities. A contrast medium, usually a radiocontrast agent such as barium sulfate mixed with water, is ingested or instilled into the gastrointestinal tract, and X-rays are used to create radiographs of the regions of interest. The barium enhances the visibility of the relevant parts of the gastrointestinal tract by coating the inside wall of the tract and appearing white on the film. This in combination with other plain radiographs allows for the imaging of parts of the upper gastrointestinal tract such as the pharynx, larynx, esophagus, stomach, and small intestine such that the inside wall lining, size, shape, contour, and patency are visible to the examiner. With fluoroscopy, it is also possible to visualize the functional movement of examined organs such as swallowing, ...
The scanner platform generates a 3 D volume of the subject's head every TR. This consists of an array of voxel intensity values, one value per voxel in the scan. The voxels are arranged one after the other, unfolding the three-dimensional structure into a single line. Several such volumes from a session are joined together to form a 4 D volume corresponding to a run, for the time period the subject stayed in the scanner without adjusting head position. This 4 D volume is the starting point for analysis. The first part of that analysis is preprocessing. The first step in preprocessing is conventionally slice timing correction. The MR scanner acquires different slices within a single brain volume at different times, and hence the slices represent brain activity at different timepoints. Since this complicates later analysis, a timing correction is applied to bring all slices to the same timepoint reference. This is done by assuming the timecourse of a voxel is smooth when plotted as a dotted line. ...
Scintillography is mainly used in scintillation cameras in experimental physics. For example, huge neutrino detection underground tanks filled with tetrachloroethylene are surrounded by arrays of photo detectors in order to capture the extremely rare event of a collision between the fluid's atoms and a neutrino. Another extensive use of scintillography is in medical imaging techniques which use gamma ray detectors called gamma cameras. Detectors coated with materials which scintillate when subjected to gamma rays are scanned with optical photon detectors and scintillation counters. The subjects are injected with special radionuclides which irradiate in the gamma range inside the region of interest, such as the heart or the brain. A special type of gamma camera is the SPECT (Single Photon Emission Computed Tomography). Another medical scintillography technique, the Positron-emission tomography (PET), which uses the scintillations provoked by electron-positron annihilation phenomena. ...
The raw data collected by a PET scanner are a list of 'coincidence events' representing near-simultaneous detection (typically, within a window of 6 to 12 nanoseconds of each other) of annihilation photons by a pair of detectors. Each coincidence event represents a line in space connecting the two detectors along which the positron emission occurred (i.e., the line of response (LOR)).. Analytical techniques, much like the reconstruction of computed tomography (CT) and single-photon emission computed tomography (SPECT) data, are commonly used, although the data set collected in PET is much poorer than CT, so reconstruction techniques are more difficult. Coincidence events can be grouped into projection images, called sinograms. The sinograms are sorted by the angle of each view and tilt (for 3D images). The sinogram images are analogous to the projections captured by computed tomography (CT) scanners, and can be reconstructed in a similar way. However, the statistics of the data are much worse ...
The radiation used in CT scans can damage body cells, including DNA molecules, which can lead to cancer.[12] According to the National Council on Radiation Protection and Measurements, between the 1980s and 2006, the use of CT scans has increased sixfold (+500%). The radiation doses received from CT scans is variable. Compared to the lowest dose x-ray techniques, CT scans can have 100 to 1,000 times higher dose than conventional X-rays.[45] However, a lumbar spine x-ray has a similar dose as a head CT.[46] Articles in the media often exaggerate the relative dose of CT by comparing the lowest-dose x-ray techniques (chest x-ray) with the highest-dose CT techniques. In general, the radiation dose associated with a routine abdominal CT has a radiation dose similar to 3 years average background radiation (from cosmic radiation).[47] Some experts note that CT scans are known to be "overused," and "there is distressingly little evidence of better health outcomes associated with the current high rate of ...
The WHO committee did not have enough data to create definitions for men or other ethnic groups.[5] Special considerations are involved in the use of DXA to assess bone mass in children. Specifically, comparing the bone mineral density of children to the reference data of adults (to calculate a T-score) will underestimate the BMD of children, because children have less bone mass than fully developed adults. This would lead to an over-diagnosis of osteopenia for children. To avoid an overestimation of bone mineral deficits, BMD scores are commonly compared to reference data for the same gender and age (by calculating a Z-score). Also, there are other variables in addition to age that are suggested to confound the interpretation of BMD as measured by DXA. One important confounding variable is bone size. DXA has been shown to overestimate the bone mineral density of taller subjects and underestimate the bone mineral density of smaller subjects. This error is due to the way by which DXA calculates ...
After completion of surgery, the patient is transferred to the post anesthesia care unit and closely monitored. When the patient is judged to have recovered from the anesthesia, he/she is either transferred to a surgical ward elsewhere in the hospital or discharged home. During the post-operative period, the patient's general function is assessed, the outcome of the procedure is assessed, and the surgical site is checked for signs of infection. There are several risk factors associated with postoperative complications, such as immune deficiency and obesity. Obesity has long been considered a risk factor for adverse post-surgical outcomes. It has been linked to many disorders such as obesity hypoventilation syndrome, atelectasis and pulmonary embolism, adverse cardiovascular effects, and wound healing complications.[11] If removable skin closures are used, they are removed after 7 to 10 days post-operatively, or after healing of the incision is well under way. It is not uncommon for surgical ...
For flexible tomographic reconstruction, open source toolboxes are available, such as TomoPy[5], ODL or the ASTRA toolbox.[6][7] TomoPy is an open-source Python toolbox to perform tomographic data processing and image reconstruction tasks at the Advanced Photon Source at Argonne National Laboratory. TomoPy toolbox is specifically designed to be easy to use and deploy at a synchrotron facility beamline. It supports reading many common synchrotron data formats from disk through Scientific Data Exchange,[8] and includes several other processing algorithms commonly used for synchrotron data. TomoPy also includes several reconstruction algorithms, which can be run on multi-core workstations and large-scale computing facilities.[9] The ASTRA Toolbox is a MATLAB toolbox of high-performance GPU primitives for 2D and 3D tomography, from 2009-2014 developed by iMinds-Vision Lab, University of Antwerp and since 2014 jointly developed by iMinds-VisionLab, UAntwerpen and CWI, Amsterdam. The toolbox supports ...
In the average person, the diaphragm should be intersected by the 5th to 7th anterior ribs at the mid-clavicular line, and 9 to 10 posterior ribs should be viewable on a normal PA inspiratory film. An increase in the number of viewable ribs implies hyperinflation, as can occur, for example, with obstructive lung disease or foreign body aspiration. A decrease implies hypoventilation, as can occur with restrictive lung disease, pleural effusions or atelectasis. Underexpansion can also cause interstitial markings due to parenchymal crowding, which can mimic the appearance of interstitial lung disease. Enlargement of the right descending pulmonary artery can indirectly reflect changes of pulmonary hypertension, with a size greater than 16 mm abnormal in men and 15 mm in women.[6] Appropriate penetration of the film can be assessed by faint visualization of the thoracic spines and lung markings behind the heart. The right diaphragm is usually higher than the left, with the liver being situated ...
The patient must be placed supine, without the head or any extremities dangling over the edge of the table. Measurement of ankle blood pressures in a seated position will grossly overestimate the ABI (by approximately 0.3). A Doppler ultrasound blood flow detector, commonly called Doppler wand or Doppler probe, and a sphygmomanometer (blood pressure cuff) are usually needed. The blood pressure cuff is inflated proximal to the artery in question. Measured by the Doppler wand, the inflation continues until the pulse in the artery ceases. The blood pressure cuff is then slowly deflated. When the artery's pulse is re-detected through the Doppler probe the pressure in the cuff at that moment indicates the systolic pressure of that artery. The higher systolic reading of the left and right arm brachial artery is generally used in the assessment. The pressures in each foot's posterior tibial artery and dorsalis pedis artery are measured with the higher of the two values used as the ABI for that leg.[2] ...
