The endovascular management of blue finger syndrome. (1/1210)

OBJECTIVES: To review our experience of the endovascular management of upper limb embolisation secondary to an ipsilateral proximal arterial lesion. DESIGN: A retrospective study. MATERIALS AND METHODS: Over 3 years, 17 patients presented with blue fingers secondary to an ipsilateral proximal vascular lesion. These have been managed using transluminal angioplasty (14) and arterial stenting (five), combined with embolectomy (two) and anticoagulation (three)/anti-platelet therapy (14). RESULTS: All the patients were treated successfully. There have been no further symptomatic embolic episodes originating from any of the treated lesions, and no surgical amputations. Complications were associated with the use of brachial arteriotomy for vascular access. CONCLUSIONS: Endovascular techniques are safe and effective in the management of upper limb embolic phenomena associated with an ipsilateral proximal focal vascular lesion.  (+info)

Infrainguinal revascularisation in the era of vein-graft surveillance--do clinical factors influence long-term outcome? (2/1210)

OBJECTIVES: To investigate the variables affecting the long-term outcome of infrainguinal vein bypass grafts that have undergone postoperative surveillance. DESIGN: A retrospective analysis. PATIENTS AND METHODS: Details of 299 consecutive infrainguinal vein grafts performed in 275 patients from a single university hospital were collected and analysed. All grafts underwent postoperative duplex surveillance. Factors affecting patency, limb salvage and survival rates were examined. These factors were gender, diabetes, hypertension, aspirin, warfarin, ischaemic heart disease, run-off, graft type, early thrombectomy, level of anastomoses and indication for surgery. RESULTS: The 6-year primary, primary assisted and secondary patency rates were 23, 47, and 57%, respectively. Six-year limb salvage and patient survival were 68 and 45%, respectively. Primary patency was adversely influenced by the use of composite vein grafts. Early thrombectomy was the only factor that significantly influenced secondary patency. Limb salvage was worse in diabetic limbs, limbs with poor run-off and in grafts that required early thrombectomy. Postoperative survival was better in males, claudicants and in patients who took aspirin. CONCLUSIONS: Although co-morbid factors did not influence graft patency rates, diabetes did adversely effect limb salvage. This study, like others before it, confirms that aspirin significantly reduces long-term mortality in patients undergoing infrainguinal revascularisation.  (+info)

Endothelial implants inhibit intimal hyperplasia after porcine angioplasty. (3/1210)

The perivascular implantation of tissue-engineered endothelial cells around injured arteries offers an opportunity to study fundamental vascular physiology as well as restore and improve tissue function. Cell source is an important issue because the ability to implant either xenogeneic or allogeneic cells would greatly enhance the clinical applications of tissue-engineered grafts. We investigated the biological and immunological responses to endothelial cell xenografts and allografts in pigs 4 weeks after angioplasty of the carotid arteries. Porcine or bovine aortic endothelial cells were cultured within Gelfoam matrices and implanted in the perivascular space of 42 injured arteries. Both porcine and bovine endothelial cell grafts reduced the restenosis index compared with control by 54% and 46%, respectively. Perivascular heparin release devices, formulated to release heparin at twice the rate of release of heparan sulfate proteoglycan from endothelial cell implants, produced no significant reduction in the restenosis index. Endothelial cell implants also reduced occlusive thrombosis compared with control and heparin release devices. Host immune responses to endothelial implants were investigated by immunohistochemical examination of explanted devices and by immunocytochemistry of serum samples. The bovine cell grafts displayed infiltration of leukocytes, consisting primarily of lymphocytes, and caused an increase in antibodies detected in serum samples. Reduced cellular infiltration and no humoral response were detected in animals that received allografts. Despite the difference in immune response, the biological effects of xenografts or allografts did not differ significantly.  (+info)

Long-term functional status and quality of life after lower extremity revascularization. (4/1210)

OBJECTIVE: The objective of this study was to assess the longer term (up to 7 years) functional status and quality of life outcomes from lower extremity revascularization. METHODS: This study was designed as a cross-sectional telephone survey and chart review at the University of Minnesota Hospital. The subjects were patients who underwent their first lower extremity revascularization procedure or a primary amputation for vascular disease between January 1, 1989, and January 31, 1995, who had granted consent or had died. The main outcome measures were ability to walk, SF-36 physical function, SF-12, subsequent amputation, and death. RESULTS: The medical records for all 329 subjects were reviewed after the qualifying procedures for details of the primary procedure (62.6% arterial bypass graft, 36.8% angioplasty, 0.6% atherectomy), comorbidities (64% diabetics), severity of disease, and other vascular risk factors. All 166 patients who were living were surveyed by telephone between June and August 1996. At 7 years after the qualifying procedure, 73% of the patients who were alive still had the qualifying limb, although 63% of the patients had died. Overall, at the time of the follow-up examination (1 to 7.5 years after the qualifying procedure), 65% of the patients who were living were able to walk independently and 43% had little or no limitation in walking several blocks. In a multiple regression model, patients with diabetes and patients who were older were less likely to be able to walk at follow-up examination and had a worse functional status on the SF-36 and a lower physical health on the SF-12. Number of years since the procedure was not a predictor in any of the analyses. CONCLUSION: Although the long-term mortality rate is high in the population that undergoes lower limb revascularization, the survivors are likely to retain their limb over time and have good functional status.  (+info)

Economics of myocardial perfusion imaging in Europe--the EMPIRE Study. (5/1210)

BACKGROUND: Physicians use myocardial perfusion imaging to a variable extent in patients presenting with possible coronary artery disease. There are few clinical data on the most cost-effective strategy although computer models predict that routine use of myocardial perfusion imaging is cost-effective. OBJECTIVES: To measure the cost-effectiveness of four diagnostic strategies in patients newly presenting with possible coronary artery disease, and to compare cost-effectiveness in centres that routinely use myocardial perfusion imaging with those that do not. METHODS: We have studied 396 patients presenting to eight hospitals for the diagnosis of coronary artery disease. The hospitals were regular users or non-users of myocardial perfusion imaging with one of each in four countries (France, Germany, Italy, United Kingdom). Information was gathered retrospectively on presentation, investigations, complications, and clinical management, and patients were followed-up for 2 years in order to assess outcome. Pre- and post-test probabilities of coronary artery disease were computed for diagnostic tests and each test was also assigned as diagnostic or part of management. Diagnostic strategies defined were: 1: Exercise electrocardiogram/coronary angiography, 2: exercise electrocardiogram/myocardial perfusion imaging/coronary angiography, 3: myocardial perfusion imaging/coronary angiography, 4: coronary angiography. Primary outcome measures were the cost and accuracy of diagnosis, the cost of subsequent management, and clinical outcome. Secondary measures included prognostic power, normal angiography rate, and rate of angiography not followed by revascularization. RESULTS: Mean diagnostic costs per patient were: strategy 1: 490 Pounds, 2: 409 Pounds, 3: 460 Pounds, 4: 1253 Pounds (P < 0.0001). Myocardial perfusion imaging users: 529 Pounds, non-users 667 Pounds (P = 0.006). Mean probability of the presence of coronary artery disease when the final clinical diagnosis was coronary artery disease present were, strategy 1: 0.85, 2: 0.82, 3: 0.97, 4: 1.0 (P < 0.0001), users 0.93, non-users 0.88 (P = 0.02), and when coronary artery disease was absent, 1: 0.26, 2: 0.22, 3: 0.16, 4: 0.0 (P < 0.0001), users 0.21, non-users 0.20 (P = ns). Total 2-year costs (coronary artery disease present/absent) were: strategy 1: 4453 Pounds/710 Pounds, 2: 3842 Pounds/478 Pounds, 3: 3768 Pounds/574 Pounds, 4: 5599 Pounds/1475 Pounds (P < 0.05/0.0001), users: 5563 Pounds/623 Pounds, non-users: 5428 Pounds/916 Pounds (P = ns/0.001). Prognostic power at diagnosis was higher (P < 0.0001) and normal coronary angiography rate lower (P = 0.07) in the scintigraphic centres and strategies. Numbers of soft and hard cardiac events over 2 years and final symptomatic status did not differ between strategy or centre. CONCLUSION: Investigative strategies using myocardial perfusion imaging are cheaper and equally effective when compared with strategies that do not use myocardial perfusion imaging, both for cost of diagnosis and for overall 2 year management costs. Two year patient outcome is the same.  (+info)

Health-related quality of life after angioplasty and stent placement in patients with iliac artery occlusive disease: results of a randomized controlled clinical trial. The Dutch Iliac Stent Trial Study Group. (6/1210)

BACKGROUND: To assess the quality of life in patients with iliac artery occlusive disease, we compared primary stent placement versus primary angioplasty followed by selective stent placement in a multicenter randomized controlled trial. METHODS AND RESULTS: Quality-of-life assessments were completed by 254 patients in a telephone interview. Assessment measures consisted of the RAND 36-Item Health Survey 1.0, time tradeoff, standard gamble, rating scale, health utilities index, and EuroQol-5D. The interviews were performed before treatment and after 1, 3, 12, and 24 months. When the 2 treatments were compared, no significant difference was observed (P>0.05). All measurements showed a significant improvement in the quality of life after treatment (P<0.05). The RAND 36-Item Health Survey measures physical functioning, role limitations caused by physical problems, and bodily pain and the EuroQol-5D were the most sensitive to the impact of revascularization. CONCLUSIONS: Health-related quality of life improves equally after primary stent placement and primary angioplasty with selective stent placement in the treatment of intermittent claudication caused by iliac artery occlusive disease.  (+info)

Isolated inferior mesenteric artery revascularization for chronic visceral ischemia. (7/1210)

PURPOSE: Complete visceral artery revascularization is recommended for the treatment of chronic visceral ischemia. However, in rare cases, it may not be possible to revascularize either the celiac or superior mesenteric (SMA) arteries. We have managed a series of patients with isolated revascularization of the inferior mesenteric artery (IMA) and now report our experience gained over a period of three decades. METHODS: Records were reviewed from 11 patients with chronic visceral ischemia who underwent isolated IMA revascularization (n = 8) or who, because of failure of concomitant celiac or SMA repairs, were functionally left with an isolated IMA revascularization (n = 3). All the patients had symptomatic chronic visceral ischemia documented with arteriography. Five patients had recurrent visceral ischemia after failed visceral revascularization, and two patients had undergone resection of ischemic bowel. The celiac or the SMA was unsuitable for revascularization in five cases, and extensive adhesions precluded safe exposure of the celiac or the SMA in five cases. IMA revascularization techniques included: bypass grafting (n = 4), transaortic endarterectomy (n = 4), reimplantation (n = 2), and patch angioplasty (n = 1). RESULTS: There was one perioperative death, and the remaining 10 patients had cured or improved conditions at discharge. One IMA repair thrombosed acutely but was successfully revascularized at reoperation. The median follow-up period was 6 years (range, 1 month to 13 years). Two patients had recurrent symptoms develop despite patent IMA repairs and required subsequent visceral revascularization; interruption of collateral circulation by prior bowel resection may have contributed to recurrence in both patients. Objective follow-up examination with arteriography or duplex scanning was available for eight patients at least 1 year after IMA revascularization, and all underwent patent IMA repairs. There were no late deaths as a result of bowel infarction. CONCLUSION: Isolated IMA revascularization may be useful when revascularization of other major visceral arteries cannot be performed and a well-developed, intact IMA collateral circulation is present. In this select subset of patients with chronic visceral ischemia, isolated IMA revascularization can achieve relief of symptoms and may be a lifesaving procedure.  (+info)

Impact of race on the treatment for peripheral arterial occlusive disease. (8/1210)

PURPOSE: The purpose of this study was to determine the impact of race on the treatment of peripheral artery occlusive disease (PAOD) and to examine the role of access to care and disease distribution on the observed racial disparity. METHODS: The study was performed as a retrospective analysis of hospital discharge abstracts from 1992 to 1995 in 202 non-federal, acute-care hospitals in the state of Florida. The subjects were patients older than 44 years of age who underwent major lower extremity amputation or revascularization (bypass grafting or angioplasty) for PAOD. The main outcome measures were incidence of intervention, incidence per demographic group, multivariate predictors of amputation versus revascularization, multivariate predictors of amputation versus revascularization among those patients with access to sophisticated care (hospital with arteriographic capabilities), and multivariate predictors of surgical bypass graft type (aortoiliac vs infrainguinal). RESULTS: A total of 51,819 procedures (9.1 per 10,000 population) were performed for PAOD during the study period and included 15,579 major lower extremity amputations (30.1%) and 36,240 revascularizations (69.9%). Although the incidence of a procedure for PAOD was comparable between African Americans and whites (9.0 vs 9.6 per 10, 000 demographic group), the incidence of amputation (5.0 vs 2.5 per 10,000 demographic group) was higher and the incidence of revascularization (4.0 vs 7.1 per 10,000 demographic group) was lower among African Americans. Furthermore, multivariate analysis results showed that African Americans (odds ratio, 3.79; 95% confidence interval [CI], 3.34 to 4.30) were significantly more likely than whites to undergo amputation as opposed to revascularization. The secondary multivariate analyses results revealed that African Americans (odds ratio, 2.29; 95% CI, 1.58 to 3. 33) were more likely to undergo amputation among those patients (n = 9193) who underwent arteriography during the procedural admission and to undergo infrainguinal bypass grafting (odds ratio, 2.00; 95% CI, 1.48 to 2.71) among those patients (n = 27,796) who underwent surgical bypass grafting. CONCLUSION: There is a marked racial disparity in the treatment of patients with PAOD that may be caused in part by differences in the severity of disease or disease distribution.  (+info)

Angioplasty and stenting is a procedure to improve the blood flow in an artery or vein. It involves threading a thin tube with a balloon at its tip through the artery to the blocked portion. The balloon is inflated opening up the artery. A stent is placed to prop it open. A stent is a mesh tube.
Subintimal recanalization is a key intervention for the treatment of CTO given the high technical success rate.[8] The most difficult aspect of this method of recanalization is reentry into the true lumen distal to the diseased vessel segment. The SAFARI method serves to increase technical success in this regard and has proven to be an effective intervention for CTOs through the subintimal plane.[6] If both wires are in the subintimal plane, a technique to increase technical success of connecting the antegrade and retrograde accesses includes the confluent balloon technique in which inflation of kissing antegrade and retrograde balloons creates one or more tears in the intima that allows communication between the two accesses.[9] If one wire is in the true lumen and the other in the false lumen, the targeted reentry technique is a method that involves placement of a snare in the true lumen as a target for a reentry device in the false lumen.[10] Another method to increase technical success of ...
Influence of stent-assisted angioplasty on cognitive function and affective disorder in elderly patients with symptomatic vertebrobasilar artery stenosis - Order reprints #890592
PCB has been used for BMS-ISR because previous studies have shown that PCB angioplasty is safe and effective in treating BMS-ISR (1). Although PCB is now widely used, there are few reports on intracoronary imaging of the drug-coated neointima after PCB angioplasty. In the current report, slow-flow phenomenon after PCB angioplasty was observed, and OCT and CAS nicely revealed drug-coated neointimal plaque after PCB angioplasty. To our knowledge, this is the first report of the case that slow-flow phenomenon occurred after PCB angioplasty and drug-coated neointimal plaque was evaluated by OCT and CAS. It was reported that PCB angioplasty was associated with diminished endothelial-dependent vasomotor function (2) and acute decrease in coronary flow reserve (3). In these cases, the slow-flow phenomenon after PCB angioplasty was partly caused by an impaired microvascular response as a result of drugs. In addition, CAS revealed white granular materials that might indicate undissolved drugs on the ...

A stent, or mesh tube, is usually inserted to keep the opening intact. By quickly locating and treating the site of the blockage, emergency angioplasty reduces the damage to heart muscle and helps the heart function better in the future ...
The latest version of the legislation (A-3769) is led by Assembly members Andrew Zwicker and Roy Freiman (both D-Hunterdon), and Joann Downey (D-Middlesex); a Senate version, sponsored by Sens. Joseph Vitale (D-Middlesex), the longtime health committee chairman, and Vin Gopal (D-Ocean), awaits a hearing. The proposal would update hospital licensing laws to enable certain qualified hospitals, without cardiac surgery centers, to apply for the elective angioplasty designation and, if they meet the state requirements, forces the DOH to approve their applications. To qualify, facilities would need to have been doing diagnostic and emergency angioplasty for at least six months, with a volume of at least 250 patients a year. They would also need to maintain a 200 patient-per-year volume going forward to maintain the expanded license, the bill notes. Hunterdon Healthcare is hopeful that this pending legislation will bring us one step closer in providing our community elective angioplasty. We already ...

Background and aim: Cerebral hyperperfusion syndrome (CHS) including intracranial hemorrhage (ICH) is a serious complication after carotid artery stenting (CAS). Staged angioplasty (SAP), undersized-balloon angioplasty followed by delayed CAS, was reported to be a potential preventable method against CHS. The aim of this study was to clarify the efficacy of SAP to prevent CHS after endovascular carotid revascularization for high-risk patients of CHS.. Methods: The STOP CHS study is a multicenter, retrospective study which registered 535 high-risk patients of CHS from 45 Japanese centers, who underwent regular CAS, SAP or angioplasty performed by board-certified neurointerventionists between October 2007 and March 2014. Selection of high-risk patients of CHS was based on imaging tests, such as single-photon emission computed tomography with acetazolamide.

TY - JOUR. T1 - Does stent placement improve the results of ineffective or complicated iliac artery angioplasty?. AU - Treiman, G. S.. AU - Schneider, P. A.. AU - Lawrence, P. F.. AU - Pevec, W. C.. AU - Bush, R. L.. AU - Ichikawa, L.. AU - Ahn, S. S.. AU - Freischlag, J.. AU - Baker, D.. PY - 1998. Y1 - 1998. N2 - Objective: This study was undertaken to determine the results and complications of stents placed for initially unsuccessful or complicated iliac percutaneous transluminal angioplasty (PTA), the effect of location (external iliac or common iliac) on outcome, and the influence of superficial femoral artery patency on benefit. Design: From 1992 through 1997, 350 patients underwent iliac artery PTA at the authors institutions. Of this group, 88 patients (88 arteries) had one or more stents placed after PTA (140 stents in total) for residual stenosis or pressure gradient (63 patients), iliac dissection (12 patients), long-segment occlusion (10 patients), or recurrent stenosis (3 ...
The results of this study suggest that carotid stenting is as effective as carotid endarterectomy for middle-term prevention of ipsilateral stroke, but the safety of carotid stenting needs to be improved before it can be used as an alternative to carotid endarterectomy in patients with symptomatic c …
Carotid angioplasty (kuh-ROT-id AN-jee-o-plas-tee) is a procedure that opens clogged arteries to prevent or treat stroke. The carotid arteries are located on each side of your neck and are the main arteries supplying blood to your brain. The procedure involves temporarily inserting and inflating a tiny balloon where your carotid artery is clogged to widen the artery.
Our aim was to determine whether CT angiography is suitable for the evaluation of in-stent restenoses in small vessel stents for intracranial angioplasty. Therefore, we simulated stenoses with degrees of 25, 50, 75 and 90% in a total of 12 stents with different designs (MEDTRONIC AVE; ABBOT BioDivYs …
Angioplasty, also known as balloon angioplasty and percutaneous transluminal angioplasty (PTA), is a minimally invasive, endovascular procedure to widen narrowed or obstructed arteries or veins, typically to treat arterial atherosclerosis. A deflated balloon attached to a catheter (a balloon catheter) is passed over a guide-wire into the narrowed vessel and then inflated to a fixed size. The balloon forces expansion of the blood vessel and the surrounding muscular wall, allowing an improved blood flow. A stent may be inserted at the time of ballooning to ensure the vessel remains open, and the balloon is then deflated and withdrawn. Angioplasty has come to include all manner of vascular interventions that are typically performed percutaneously. The word is composed of the combining forms of the Greek words ἀγγεῖον angeîon vessel or cavity (of the human body) and πλάσσω plássō form or mould. A coronary angioplasty is a therapeutic procedure to treat the stenotic ...

With regard to the generalizability of the conclusions of this combined analysis to other established or proposed primary PCI programs, it should be noted that the vast majority of patients underwent primary PCI at established angioplasty centers. Although in the DANAMI 2 study, 3 of the 5 PCI centers had not performed primary PCI before study participation, in the 5 other studies, the PCI centers, most often high-volume centers, were already experienced in primary angioplasty before the study. From the standpoint of the combined analysis, it cannot therefore be assumed that primary angioplasty in low-volume centers by low-volume operators, particularly without prior experience of the technique, could achieve the overall success seen in this analysis.. The present combined analysis has a number of limitations. Although the literature was thoroughly searched, all recent international cardiac conferences were scrutinized and foreign colleagues from other interventional centers were consulted, it ...
Patients who undergo bypass surgery for heart disease have better long-term survival rates than those who opt for less invasive procedures like angioplasty, a major US study showed on Tuesday.. The study looked at data from 190,000 US patients and found that those who had bypass surgery had a lower death rate in the first four years (16.4 percent) compared to those who had angioplasty (20.8 percent).. Bypass operations involve open heart surgery to create a detour around a blocked artery using a vein taken from somewhere else in the patients body.. The type of angioplasty examined in the study, known as percutaneous coronary intervention (PCI), involves a small incision to thread a balloon, a wire stent or a tube through the blocked artery to keep it open.. Our study is the most general one ever done because it uses data from across the whole country. It is also much larger than any other study, said William Weintraub, chair of cardiology at Christiana Care Health System and the studys lead ...
The goal of an angioplasty is to unblock the artery and get blood flowing to the heart again. Other names that you may hear for an angioplasty are Percutaneous Coronary Intervention (PCI) and Percutaneous Transluminal Coronary Angioplasty (PTCA).

The CARESS study from Milan and London has shown that for younger, high-risk patients experiencing a myocardial infarction there can be a clear benefit from performing angioplasty as soon as it is available after using lytics with anti-platelet therapy in situations where primary angioplasty is not available. This answers a huge un-met need of what is best to do for patients who are admitted initially to a centre where primary percutaneous intervention is not an immediate option. At the cardiology congress in Vienna Carlo Di Mario told Peter Goodwin that patients at lower risk of bleeding who can proceed to angioplasty should do so ...
What is balloon angioplasty and stent placement? During balloon angioplasty a long, thin tube called a catheter is inserted through an artery in your groin or forearm, and a thin wire known as a guidewire is used to guide the catheter into th
Since the mid 1990s wire mesh stents have become a standard part of the angioplasty procedure. Unfortunately, these wire cylinders (stents) irritate the smooth muscle cells of the artery walls causing these cells to grow aggressively (to proliferate). This growth is an effort by the body to cover up the foreign metal that has just been introduced into the artery by the surgeon. This should not be surprising. Whenever an irritating alien material is placed in the body, cells grow around it in order to isolate the unfamiliar substance, which the body perceives as potentially harmful. The growth of the muscle cells (and blood clots) eventually closes 20% to 41% of the arteries containing these metal mesh stents.8 Furthermore, the use of stents results in no better survival than angioplasty alone7,9-and remember angioplasty does not improve the chances of living longer.3,4 If only treatments could be developed to stop these cells from growing. Scientists had to look no further than cancer therapy to ...

Patients are wildly enthusiastic about these treatments. Thereve been focus groups with prospective patients who have stunningly exaggerated expectations of efficacy. Some believed that angioplasty would extend their life expectancy by 10 years! Angioplasty can save the lives of heart-attack patients. But for patients with stable coronary disease, who comprise a large share of angioplasty patients? It has not been shown to extend life expectancy by a day, let alone 10 years-and its done a million times a year in this country. Jones adds wryly, If anyone does come up with a treatment that can extend anyones life expectancy by 10 years, let me know where I can invest ...

Carotid angioplasty and stenting - When the location of the narrowing or blockage is too difficult for the surgeon to access directly or when you have other health conditions that make surgery too risky, your doctor may recommend a procedure called carotid angioplasty and stenting. While youre under local anesthesia, a tiny balloon is threaded by catheter to the area where your carotid artery is clogged. It is then inflated to widen the artery, and a small wire mesh coil called a stent is inserted to keep the artery from narrowing again. ...
