Hybrid treatment of aberrant subclavian artery aneurysm. Case report. (1/963)

A 62-year-old man was incidentally diagnosed with a completely asymptomatic aberrant right subclavian artery (ARSA) aneurysm with a maximum diameter of 4.5 cm. This condition presents a postrupture mortality rate of 50% and the morbidity-mortality rates reported in the literature with traditional open repair procedures are of 25%. In our patient we planned a hybrid procedure and excluded the aneurysm by performing, first, a right carotid-subclavian bypass with ligation of the subclavian artery upstream from the vertebral artery and the internal mammary artery and, the day after, by covering its origin from the aortic arch with the placement of a thoracic endoprosthesis. A third session was necessary, three days later, because of a leak; a complete resolution of the condition was achieved by embolizing the still perfused residual aneurysmal sac with Balt metallic coils.  (+info)

Staged hybrid treatment of complex ascending aortic and distal aortic arch pseudoaneurysm after repair of aortic coarctation. (2/963)

A 49-year-old operated for aortic coartaction patient presented with thoracic and ascending aortic aneurysm. He was asymptomatic. Angio-magnetic resonance nuclear scan and angiography revealed an ascending aortic aneurysm (5.2 cm), bicuspid aortic valve, 6-cm proximal descending aortic pseudoaneurysm at the site of the previous operation with involvement of the left subclavian artery. Restenosis at the original site of coarctation and aortic arch hypoplasia distally to the brachiocefalic trunk was also found. The operation performed was a "modified Bentall - De Bono". The pseudoaneurysm was not accessible through median sternotomy due to the massive lung adhesions following the previous surgery. The left common carotid artery was explanted from the aortic arch and connected with a graft to the ascending aortic conduit. A proximal neck suitable for landing zone of the endovascular stent-graft was then established. The postoperative course was uneventful. After two weeks, the patient was readmitted. The exclusion of the thoracic descending aortic pseudoaneurysm by endovascular implantation of the stent-graft prosthesis was performed. The left subclavian artery was excluded because left vertebral artery was closed. The patient did not develop hand claudicatio. The procedure was successful.  (+info)

Spinal cord ischemia after endovascular treatment of infrarenal aortic aneurysm. Case report and literature review. (3/963)

Spinal cord ischemia is a rare but catastrophic complication after endovascular treatment of infrarenal aortic aneurysm: only 14 cases are reported in the literature. A patient with a 6 cm infrarenal aortic aneurysm extending to both common iliac arteries and high surgical risk was submitted to endovascular repair with exclusion of both hypogastric arteries and surgical revascularization of the right hypogastric artery. The patient presented paraplegia, apallesthesia and superficial hyposensitivity immediately after the procedure. A spinal cord drainage was positioned with little improvement of superficial sensitivity. We undertook a systematic review of the literature on this topic.  (+info)

Treatment of a large postsurgical para-anastomotic aortic aneurysm using endovascular stent grafts. A case report with four-year follow-up. (4/963)

This case report describes the outcome of straight endograft placement for treating a large para-anastomotic aortic aneurysm (PAA). A 43-year-old woman was admitted to the emergency department because of a vast PAA (8.7 cm in maximum transverse diameter). Since 1983, she has undergone multiple vascular operations for arterial occlusive disease. In 1990, an aortobifemoral bypass operation was performed. In this most recent intervention, we implanted three tube Excluder(R) endografts. The procedure was uneventful. Considering the size of the aneurysm sac, particular attention was paid to possible sequelae during the over 4-year follow-up period. No complications developed and the last computed tomography (CT) scan showed a remarkable decrease of 50 mm in aneurysm size. In conclusion, the use of straight endografts seems to be effective and lasting, even in large para-anastomotic aneurysmatic lesions.  (+info)

Anesthesia for endovascular surgery of the abdominal aorta. (5/963)

BACKGROUND AND OBJECTIVES: Endovascular surgery for aneurism of the aorta is less invasive than the conventional procedure besides other advantages such as the absence of abdominal incision, absence of ligature of the aorta, and reduced postoperative recovery time. Since it is a relatively new procedure and to presenting a series of changes that should be known by the anesthesiologist, the objective of this report was to review the most relevant aspects of endovascular surgery, allowing more adequate perioperative anesthetic management. CONTENTS: A brief description of the technique of endovascular aneurism repair, possible vantages and disadvantages of its use, as well as potential complications are discussed. CONCLUSIONS: Knowledge of the changes secondary to the endovascular procedure allows a more adequate anesthetic conduct and improves the postoperative results in those patients.  (+info)

Background: Despite recent technical advances in endovascular recanalization, there is skepticism regarding its clinical effectiveness compared with intravenous thrombolysis for treating acute ischemic stroke. We aimed to delineate its effectiveness and safety and their change over time. Methods: Using a prospective, multicenter stroke registry database, we identified 872 patients with ischemic stroke who underwent recanalization therapy with intravenous thrombolysis alone (IVT; n = 533) or endovascular recanalization with or without intravenous thrombolysis (EVT; n = 339) between April 2008 and January 2012. All subjects had National Institute of Health Stroke Scale score of 10 or more and arrived at the hospital within 4.5 hours of onset. Propensity score was used to address baseline imbalances between treatment groups, but balance adjustment was not performed for subgroup analyses. Results: The primary outcome was modified Rankin Scale score of 0-2 at discharge. The year-by-year effectiveness ...
Boomington, Ind. ─ Cook Medical has received premarket approval from the U.S. Food and Drug Administration (FDA) for its lower-profile Zenith Alpha™ Thoracic Endovascular Graft. Zenith Alpha Thoracic is indicated for the endovascular treatment of patients with isolated lesions of the descending thoracic aorta (not including dissections) having vascular anatomy suitable for endovascular repair1. The approval of Zenith Alpha Thoracic was based on two pivotal clinical trials that studied the safety and effectiveness of the device in patients with aortic aneurysm/ulcer or blunt traumatic aortic injury.. Zenith Alpha Thoracic will allow physicians to treat more patients with TEVAR (thoracic endovascular aortic repair) because of its lower-profile introduction system and broad range of sizes. With a 16-20 French delivery system, Zenith Alpha Thoracic was developed to address vascular access issues associated with larger-profile devices and to increase conformability in tortuous anatomy.. The ...

January 12, 2016-Findings from a study on the management and outcomes of isolated renal artery aneurysms (RAAs) in the endovascular era were published by Dominique B. Buck, MD, et al in the Journal of Vascular Surgery (JVS; 2016;63:77-81). The background of the study is that isolated RAAs are rare, and controversy remains about indications for surgical repair; however, little is known about the impact of endovascular therapy on patient selection and outcomes.. The investigators concluded that more RAAs are being treated due to the advent of endovascular techniques, without a reduction in operative mortality or a reduction in open surgery, and therefore, indications for repair should be re-evaluated.. As summarized in JVS, the investigators identified all patients undergoing open or endovascular repair of isolated RAAs in the Nationwide Inpatient Sample from 1988 to 2011 for epidemiologic analysis. Elective cases were selected from the period of 2000 to 2011 to create comparable cohorts for ...
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 ...

Background: Expanded applications and increasing volumes of complex endovascular procedures have increased the risk of unintended intraoperative fragmentation and retention of catheters and sheaths. We describe a series of retained or fragmented endovascular devices, a quality improvement program to address this unmet need for improved detection of catheter fragmentation, and the results of this program. Methods: Cases utilizing endovascular devices that resulted in a retained catheter fragment were identified and analyzed during divisional quality improvement review. One consistent area of concern was operating room (OR) staff unfamiliarity with verifying the integrity of an endovascular device. In response, a slide-based training protocol of focused, endovascular nursing education was implemented. Following perceived lack of improvement after this approach, we developed a handheld visual reference display of the tips of common catheters and sheaths. Staff was surveyed before and after ...
Chronic MCA occlusion as a cause of hemodynamic ischemic stroke is not a prominent clinical issue worldwide.1 While acute occlusion of the MCA is commonly caused by an embolic thrombus,3 4 atherosclerotic occlusion of the intracranial arteries is more prevalent in Asians. Patients with chronic proximal MCA occlusion may have minor or no stroke because of well developed collaterals. Conversely, the prognosis for those with hemodynamic impairment is poorer.1 Chronic occlusive lesion does not seem to represent a significant embolic source but threatens the patient with hemodynamic ischemia and infarct. In addition, patients with MCA occlusion may have disabling cognitive impairment, especially for those with bilateral diseases.5 For our two patients, the etiology of their recurrent TIAs was likely to be hemodynamic impairment from total MCA occlusion, arising from atherosclerotic stenosis and superimposed thrombosis based on angiographic findings. The optimal management of them was ...
In total, 394 limbs were treated with an average patient age of 72.6 years, 65% of whom were male. Diabetes was present in 69% of all limbs treated. Patient demographics were well-matched across the endovascular and surgical groups, although the proportion of non-ambulatory patients was higher in the endovascular group (51% vs. 21%, p,0.0001) as was the rate of heel wound (15% vs. 8%, p=0.03).. Of the 364 limbs involved, 194 were treated with an endovascular approach and 170 with a surgery-first approach. The three-year wound healing rate for all patients was 64.2%, for the endovascular group was 53.1%, and for the surgery-first group 77.1% (p,0.0001).. Notable differences in three-year wound healing rate were seen for: patients with (53.4%) and without (79.9%) dialysis-dependent end-stage renal disease (p=0.0002); patients with (41.7%) and without (69.5%) congestive heart failure as defined by left ventricle ejection fraction ,40% (p=0.0001); ambulatory patients (76.9%) and non-ambulatory ...
The Zenith® Thoracic Dissection Study is a clinical trial to study the safety and effectiveness of the Zenith® Dissection Endovascular System in the treatment of dissections (length-wise tear) of the descending thoracic aorta. The Zenith® Dissection Endovascular System is comprised of the Zenith TX2® TAA Endovascular Graft and the Zenith® Dissection Endovascular Stent. Instead of making a large incision in the chest, the physician makes a small incision near each hip to insert, and guides the graft and the dissection stent into place in the aorta ...
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 ...

We describe a technique to gain an additional endovascular access in acute situations in which a large-bore introducer is already inserted or in situations in which multiple accesses are impaired because of other reasons. Using an existing percutaneous femoral artery access, a second guide wire is inserted into the introducer, which is later withdrawn and applied onto one of the two guide wires. A double-wire access is then achieved. This access can be used, for example, for angiography or embolization catheters. This method might be useful in situations in which a quick and unplanned extra access is needed. It is, for example, applicable in hemodynamically unstable patients in whom percutaneous access can be difficult to obtain or in aortic endovascular procedures when an unplanned access is needed to insert an additional catheter for angiography and embolization ...

If diagnostic ...
We tested the feasibility, safety, and utility of the hybrid OR in the diagnosis and treatment of various neurosurgical diseases. Combined surgery and endovascular procedures have become popular and essential processes for the treatment of complex cerebrovascular diseases. However, in general, these combined treatment processes are performed in the conventional OR and angioroom separately and patients have to be transferred between procedures. In this separation process, a lot of time is wasted on transport and the patient can be exposed to danger. Split processes imply a big inconvenience for complex cerebrovascular disease, while hybrid OR greatly reduces morbidity and mortality in complex cerebrovascular disease [3,21]. In a hybrid OR, bleeding causes can be conveniently identified, and the location of an aneurysm or arteriovenous malformation verified to avoid any blinding hemorrhage that can lead to life-threatening events during surgery [1,13]. In addition, the DSA in the OR is no longer ...

CLI is usually treated by operations or procedures that increase blood flow to the leg and foot, in order to relieve these symptoms, heal the ulcers, and preserve the limb. There are two different ways to increase the blood flow in CLI. One is with open surgery, which creates a bypass around the blockage. The other is with endovascular treatment (often called angioplasty), a minimally invasive procedure that opens the blocked arteries directly. Angioplasty is performed with balloons and other tools that clear plaque, and sometimes permanent implantation of small, mesh-like metal tubes called stents. Both types of treatment - open surgery and angioplasty - are considered reasonable and appropriate for patients with CLI like you. The study doctors have determined, on the basis of your medical history and tests, that you are eligible for both treatments ...

To gain knowledge into how endovascular therapies have been utilized, and the clinical outcomes resulting from these procedures, the group from across the US and Canada set out to review the Get With The Guidelines Stroke data from 1087 hospitals from 2003 to 2013. The type of endovascular therapy has evolved over time from initially being more geared toward intra-arterial fibrinolysis and angioplasty/stenting to later on in the data set where techniques of mechanical clot and stent retrievers were used. The authors found that 454 hospitals (41.8%) provided endovascular therapy to at least one patient during the study period and that a total of 1.6% of all ischemic stroke patients received endovascular therapy. During the same period, 8.0% of all of the ischemic stroke patients received IV TPA alone without endovascular therapy. In general, there was an increase over time of the proportion of hospitals providing endovascular therapy from 2003 to 2012, with a drop in 2013. Along the same lines, ...
A newer approach, called an endovascular repair, involves the use of a catheter that is inserted into the groin, in a similar fashion as an aortogram - however, the catheter is used to insert a self-expanding stent graft into the aneurysm. Endovascular repair of aneurysms does not require a large incision, and has a substantially shorter recovery than the conventional open surgical approach. Not all aneurysms are suitable for endovascular repair; however, vascular surgeons at UCSF Medical Center are experts in the treatment of aneurysms using both the conventional and the endovascular approach.. UCSF Medical Center has extensive experience in surgery for complex aortic aneurysms - those that involve the arteries to the kidneys or intestines - and is recognized as having one of the lowest mortality rates reported to date.. Similarly, our vascular surgeons pioneered endovascular repair of aneurysms, particularly those involving the aorta in the upper abdomen where blood vessels branch off to the ...

OBJECTIVE: The purpose of this study was to assess whether there is a difference in outcome of endovascular repair in patients with and without intraoperative adjuvant procedures. METHODS: Demographic, anatomic and operative details were assessed in patients undergoing endovascular repair using the EUROSTAR registry and correlated with morbidity and mortality rates. Three groups of adjuvant procedures: (A) endovascular, (B) surgical peripheral arterial and (C) surgical abdominal arterial were compared with a group of patients without an adjuvant procedure (D). Logistic regression and Cox proportional hazards model were used for statistical analysis. RESULTS: Of 4631 endovascular repairs, 1353 patients (29.2%) required adjuvant procedures. Additional endovascular procedures were performed in 1057 (78.1%), surgical peripheral arterial in 193 (14.3%) and surgical abdominal arterial in 103 (7.6%). The 30-day mortality rate was significantly higher in categories with peripheral arterial surgical ...
April 1, 2009 - Endovascular aortic repair (EVAR) used to repair ruptured abdominal aortic aneurysms (RAAAs) had a significant mortality benefit, according to five-year study published in the April issue of the Journal of Vascular Surgery.. 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 ...
Delirium is an acute form of nervous system dysfunction often observed in patients in the intensive care unit. Endovascular aortic repair (EVAR) is considered a minimally invasive surgical treatment for abdominal aortic aneurysm. Although the operation method is widely used, there are few investigations of the rate and risk factors of delirium development after the operation. In this study, we retrospectively examined the rate of delirium development in the intensive care unit (ICU) after EVAR, as well as the associated preoperative risk factors and effects on the lengths of ICU and hospital stays. We examined the 81 consecutive patients who underwent elective EVAR between November 2013 and August 2014. The Intensive Care Delirium Screening Checklist was used to diagnose delirium. Twenty patients (24.7%) were diagnosed with delirium in this study. The ICU and hospital length of stays of patients with delirium were 3.3 ± 2.4 days and 14.5 ± 11.9 days, respectively, the latter of which

To the Editor:. Using percutaneous catheter techniques and endovascular grafts, Ince et al1 reported successful treatment of aneurysms occurring after previous repair of aortic coarctation with no mortality and minimal morbidity in 6 patients. They contrasted these results with those reported for similar patients with open surgical treatment, in whom the mortality rates ranged between 14% and 23.5%. The 3 references reporting these outcomes were published between 1989 and 1996.. Any comparison of these 2 methods of treatment for recurrent aneurysm after coarctation repair should include contemporary reports that use modern surgical techniques. Two recent studies using the technique of full cardiopulmonary bypass and circulatory arrest in 9 patients with complications following surgical repair of aortic coarctation (including 7 patients with aneurysms or pseudoaneurysms) reported no early deaths and few major complications.2,3. Although minimally invasive endovascular techniques offer important ...
April 2, 2009 - Researchers from the University of Massachusetts Memorial Medical Centers division of vascular and endovascular surgery, 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.. Study results are published in the April issue of the Journal of Vascular Surgery.. In the study, an estimated 27,750 hospital discharges for RAAA occurred, of which 11.5 percent were treated with EVAR. Data was secured through the Nationwide Inpatient Sample to evaluate operative outcomes.. While the incidence of RAAA remained fairly constant, EVAR was used to treat RAAA in an increasing proportion of patients - from 5.9 percent in 2001 to 18.9 percent in 2006, said Andres Schanzer, M.D., assistant professor of surgery in the division. Researchers found that EVAR was independently associated with a lower postoperative ...
Background: Endovascular therapy seems to benefit a subset of patients with acute large vessel occlusions (LVO). The aim of this study was to develop a clinically useful tool to identify patients with anterior circulation large vessel occlusions who are likely to benefit from endovascular therapy.. Methods: Adults with anterior circulation LVOs were included. In the derivation cohort (2008-2012) from Grady Memorial hospital (GMH), independent predictors (p,0.2) of good outcome (mRS 0-2 at 90 days) were determined using logistic regression. Highly weighted factors were used to derive the PRE score as a predictor of good outcome. Four risk-quartiles were created based on observed rates of good outcomes. The PRE score was validated in the UPMC database (n=322, 2007-2013) and in a database from Unitat dIctus Vall dHebron (UIVH), Barcelona (n=203, 2009-2012). Performance of PRE was compared with HIAT-2, THRIVE and ASPECTS in predicting good outcome.. Results: In the derivation cohort (N=247, mean ...
A novel endovascular approach useful in the treatment of aneurysms, particularly saccular aneurysms. The present endovascular prosthesis comprises a leaf portion capable of being urged against and blocking the opening of the aneurysm thereby leading to obliteration of the aneurysm. The leaf portion is attached to, and independently moveable with respect to, a body comprising at least one expandable portion. Thus, the body serves the general purpose of fixing the endovascular prosthesis in place at a target body passageway in the vicinity at which the aneurysm is located and the leaf portion serves the purpose of blocking the aneurysmal opening thereby leading to obliteration of the aneurysm. A method of delivering and implanting the endovascular prosthesis is also described.

SEPULVEDA SCH, Nelson et al. Endovascular treatment of acute traumatic rupture of the thoracic aorta: Report of one case. Rev. méd. Chile [online]. 2003, vol.131, n.3, pp.309-313. ISSN 0034-9887. Traumatic rupture of the aorta has a near 80% mortality. Most patients die on the site of the accident. Conventional surgical repair of these lesions has a high morbidity and mortality, generally associated to the severity of associated lesions. Over the last decade, endovascular treatment has become an effective therapeutic alternative. We report a 40 years old male, that suffered a traumatic rupture of the descending thoracic aorta in a car accident. A successful endovascular repair was performed, installing an endoprothesis on the site of the lesion, using a femoral artery approach. The patient had a good postoperative evolution and was discharged from the hospital once complete rehabilitation of his associated lesions was obtained (Rev Méd Chile ...

Background: Serial ASPECTS of ischemic stroke lesion evolution from baseline to 24-hours has been established as an effective surrogate endpoint in endovascular therapy. The use of this imaging shift has not been implemented beyond thrombectomy trials to estimate impact of endovascular therapy in large-scale registry data.. Methods: The STRATIS Imaging Core Lab, blind to all clinical data, independently determined ASPECTS scores on baseline and 24-hour studies. ASPECTS regional involvement and resulting total scores were analyzed in anterior circulation occlusions in STRATIS. Statistical analyses calculated the proportion of subjects with 0 ASPECTS score shift and separately, those with shifts ,4, 5, 6 points. Clinical predictors of ASPECTS shift and regional involvement were determined.. Results: Baseline ASPECTS (n=517) was 8.2 ± 1.59 (median 8.0 (2, 10)) and 24-hour ASPECTS (n=547) was 6.0 ± 2.92 (median 7.0 (0, 10)). Serial ASPECTS (n=487) revealed change of -2.1 ± 2.41 (median-1.0 (-10, ...

In 2008, the top priority in our divisions 5-year strategic plan was to become an internationally recognized center of excellence for the endovascular treatment of complex aortic pathology extending from the aortic valve to the external iliac artery. Five components were identified as most critical to achieve this strategic priority: (1) training at centers of excellence in complex endovascular repair; (2) industry partnership to improve access to developing technologies; (3) a fully integrated team approach with one leader involved in all steps of all cases; (4) prospective data collection; and (5) development and implementation of a physician-sponsored investigational device exemption for juxtarenal, pararenal, and thoracoabdominal aneurysms. We have now performed 49 repairs (16 commercially manufactured devices, 33 physician-modified devices) for 3 common iliac, 20 juxtarenal, 9 pararenal, and 17 thoracoabdominal aneurysms, using 142 fenestrations, branches, and scallops.

Nelson Bernardo, MD, medical director for Peripheral Vascular Intervention at MHVI and director for Peripheral Interventional Research Studies at MedStar Cardiovascular Research Network, is leading a feasibility study of an investigational revascularization technique called LimFlow™.. The LimFlow System is currently indicated as a treatment for patients with end-stage CLI who have no other revascularization option-and have failed either endovascular or surgical interventions, or even both. The procedure is based on a concept devised some time ago for use in the heart to bypass occluded coronary arteries, says Dr. Bernardo.. The LimFlow procedure entails the creation of a fistula from an artery in the leg to its accompanying vein. The latter carries the oxygenated blood flow into the critically ischemic foot via venous pedal arch acting as the arterial system. The vein is accessed distally at the level of the ankle while the artery is accessed at the groin area using the antegrade femoral ...
On a more specific level pertaining to the clinical months, the fellows will mature their angiographic skills. They will be expected to develop complete knowledge of all wires, devices, and inventory. They will learn to perform upper extremity angio/intervention, renal/visceral pta/stent, carotid pta/stent, and aortic stent grafting. They will also have an introduction to complex endovascular techniques such as aortic debranching. In terms of open procedures, they will be expected to have mastered technical skills such as fine suturing. They will learn the complete steps of each operation as the primary surgeon. For example, they will learn how to completely perform a carotid endarterectomy from start to finish and understand all of the decision-making during the procedure. Fellows will gradually learn and develop independence to ready them for practice. They will continue to participate in the preoperative, perioperative and postoperative care of the patients as well as participate in daily ...
The new Simbionix ANGIO Mentor iCase (3D Systems) is a new endovascular simulation case editor which can be used to create endless training scenarios, a press release from the company states.. Virtual reality simulators are being used to help specialists learn and gain experience in procedural skills for a range of endovascular interventions. Today those simulators offer a growing number of interventions, each with a pre-defined number of cases or training hours. A simulation case includes a specific anatomy, one or more pathologies and sometimes complications. Programme directors and training managers are looking for ways to independently create new training content to extend the hands-on training time on the simulator.. One way to increase the number of training cases on the simulator is to use patient-specific simulation software. This enables clinicians to create a simulation case based on the patients CTA or MRA scans, originally used for the purpose of preoperative simulated clinical ...
Offered by Universitat de Barcelona. Acute stroke is a time-dependent medical emergency. In acute ischemic stroke, the first objective is to restore brain flow using sistemic thrombolytic treatment and, in patients with large vessel occlusion, by endovascular treatment. In hemorrhagic stroke there are also specific treatments that can improve the clinical outcome. The sooner the initiation of all these therapies the higher the clinical benefit. Thus, the organization of Stroke Code systems coordinated between emergency medical systems and hospitals is crucial to achieve early medical attention and treament. Neurological scales facilitate stroke recognition at both hospital and pre-hospital levels and provide valuable information of stroke severity. The RACE scale is a prehospital scale validated as a tool to identify patients with suspected large vessel occlusion who are potential candidates for endovascular treatment. This course aims to update general knowledge in acute stroke and currently

Continuous hemofiltration (CHF) was first described in a 1977 paper by Kramer et al. as a treatment for fluid overload.[4] Hemofiltration is most commonly used in an intensive care unit setting, where it is either given as 8- to 12-hour treatments, so called SLEF (slow extended hemofiltration), or as CHF (continuous hemofiltration), also sometimes called continuous veno-venous hemofiltration (CVVH) or continuous renal replacement therapy (CRRT).[5][6] Hemodiafiltration (SLED-F or CHDF or CVVHDF) also is widely used in this fashion. In the United States, the substitution fluid used in CHF or CHDF is commercially prepared, prepackaged, and sterile (or sometimes is prepared in the local hospital pharmacy), avoiding regulatory issues of on-line creation of replacement fluid from dialysis solution. With slow continuous therapies, the blood flow rates are usually in the range of 100-200 ml/min, and access is usually achieved through a central venous catheter placed in one of the large central veins. ...
