Abstract
A 61-year-old man presented with an acute type B aortic dissection for which a stent-graft was introduced. He remains complication-free 4 years onwards and has since been diagnosed with Ehlers-Danlos syndrome type IV (EDS IV). His particular mutation is predicted to result in lesser levels of normal collagen and may explain his favourable outcome from endovascular intervention. Understanding the genotype-phenotype correlation may influence the choice of therapy offered to patients with EDS IV.

Abstract
PURPOSE We have evaluated the efficacy of endovascular repair of distal aortic arch aneurysms (DAAA) causing recurrent laryngeal nerve palsy. MATERIAL AND METHODS Eight patients (five male and three female) with median age of 72 years (range: 59-80) presented with left recurrent laryngeal nerve palsy associated with DAAA. All patients were considered unfit for open surgery. The median aneurysm size was 5.9 cm (range: 5-7.3). Thirteen stents were deployed: eight Gore, four Endofit and one Talent. Epidural anaesthesia was used in all patients. The left subclavian artery was covered in all and the left common carotid in three who had a preliminary right to left carotid-carotid bypass. Routine follow-up (FU) was with computed tomography (CT) at 3-6 months and yearly thereafter. RESULTS Exclusion of the aneurysm sac was achieved in all patients. Thirty-day mortality was 0%, with no paraplegia or stroke. Early complications included: rupture of the external iliac artery (one) and common femoral artery thrombectomy (one). One patient died of unknown cause at 17 months. The mean FU in the remaining seven patients was 21 months (range: 6-51). Aneurysm size decreased in five, was unchanged in one and increased in one. Three patients had improvement in voice quality postoperatively. One patient had a recurrent type 1 endoleak which was restented twice. No late deaths have occurred. CONCLUSION Though technically the procedures involved were more complicated, endovascular repair of DAAA causing aorto-vocal syndrome is safe and offers a realistic alternative to open surgery. Hoarseness of the voice can improve postoperatively and is associated with reduction in aortic sac diameter.

Abstract
BACKGROUND Retroperitoneal haematoma is a rare clinical entity with variable aetiology, which is increasing in incidence mainly due to complications related to interventional procedures. There is no general consensus as to the best management plan for patients with retroperitoneal haematoma. METHODS A literature review was undertaken using MEDLINE, all relevant papers on retroperitoneal haemorrhage or haematoma were used. RESULTS The diagnosis is often delayed as symptoms are nonspecific. Retroperitoneal haematoma should be suspected in patients with significant groin, flank, abdominal, back pain or haemodynamic instability following an interventional procedure. Spontaneous haemorrhage usually occurs in patients who are anticoagulated. Multi-slice CT and arteriography are important for diagnosis. Most haemodynamically stable patients can be managed with fluid resuscitation, correction of coagulopathy and blood transfusion. Endovascular treatment involving selective intra-arterial embolisation or the deployment of stent-grafts over the punctured vessel is attaining an increasingly important role. Open repair of retroperitoneal bleeding vessels should be reserved for cases when there is failure of conservative or endovascular measures to control the bleeding. Open repair is also required if endovascular facilities or expertise is unavailable and in cases where the patient is unstable. If treated inappropriately, the mortality of patients with retroperitoneal haematoma remains high. CONCLUSION There is a lack of level I evidence for the best management plans for retroperitoneal haematoma, and evidence is based on small cohort series or isolated case reports. Conservative management should only be reserved for patients who are stable. Interventional radiology with intra-arterial embolisation or stent-grafting is the treatment of choice. Open surgery is now rarely required.

Abstract
Open surgery for thoracic aortic disease is associated with significant morbidity and the reported rates for paraplegia and stroke are 3%-19% and 6%-11%, respectively. Spinal cord ischemia and stroke have also been reported following endoluminal repair. This study reviews the incidence of paraplegia and stroke in a series of 186 patients treated with thoracic stent grafts. From July 1997 to September 2006, 186 patients (125 men) underwent endoluminal repair of thoracic aortic pathology. Mean age was 71 years (range, 17-90 years). One hundred twenty-eight patients were treated electively and 58 patients had urgent procedures. Anesthesia was epidural in 131, general in 50, and local in 5 patients. Seven patients developed paraplegia (3.8%; two urgent and five elective). All occurred in-hospital apart from one associated with severe hypotension after a myocardial infarction at 3 weeks. Four of these recovered with cerebrospinal fluid (CSF) drainage. One patient with paraplegia died and two had permanent neurological deficit. The rate of permanent paraplegia and death was 1.6%. There were seven strokes (3.8%; four urgent and three elective). Three patients made a complete recovery, one had permanent expressive dysphasia, and three died. The rate of permanent stroke and death was 2.1%. Endoluminal treatment of thoracic aortic disease is an attractive alternative to open surgery; however, there is still a risk of paraplegia and stroke. Permanent neurological deficits and death occurred in 3.7% of the patients in this series. We conclude that prompt recognition of paraplegia and immediate insertion of a CSF drain can be an effective way of recovering spinal cord function and improving the prognosis.

Abstract
Endovascular aneurysm repair (EVAR) has become an established alternative to open repair (OR). We present a consecutive series of 486 elective patients with large infra-renal aortic abdominal aneurysm, comparing OR with EVAR. Prospective data collected during an 8-year period from January 1997 to October 2005 was reviewed. Statistical analysis performed using SPSS data editor with chi(2) tests and Mann-Whitney U-tests. There were 486 patients with 329 OR (293 males, 36 females) with median age of 72 years with median diameter 6.3 cm and 157 EVAR (148 males, 9 females) with median age 75 years with median diameter 6.1 cm. Mortality was 13 (4%) for OR and 5 (3.2%) for EVAR (three of whom were in the UK EVAR 2 trial). Blood loss was significantly less for EVAR 500 ml vs. 1500 ml for OR. Sixty-five (19.8%) patients with OR had significantly more peri-operative complications compared with 14 (8.9%) with EVAR. The length of stay in hospital was significantly less for EVAR. This non-randomised study shows that although EVAR does not have a statistically significantly lower mortality, it does have statistically significantly lower complication rates compared with OR. EVAR can be achieved with good primary success, but long-term follow-up is essential to assess durability.

Abstract
Endovascular therapy has revolutionised vascular surgery. Complex open surgical procedures may be replaced with a combination of extra-anatomical reconstruction and endovascular treatment. This minimally invasive approach is associated with a lower peri-operative morbidity and mortality than open repair. We describe a novel 2-stage treatment in a patient with Type B thoracic aortic dissection with subsequent aneurysmal dilatation and the added difficulty of a concomitant aneurysmal aberrant right subclavian artery (Kommerell's diverticulum).

Abstract
PURPOSE To report the benefit of endoluminal repair of mycotic aortic aneurysms and highlight the need for a registry. METHODS Nine patients (five female) were identified over 5 years (1998-2003) as having presumed mycotic aortic aneurysms (12 in total) suitable for endoluminal grafting. A total of nine thoracic and three abdominal were grafted and followed up for a median of 36 months. RESULTS Six of the aneurysms have resolved and one was converted to an open repair. There was one early death from rupture of a second undiagnosed aneurysm and two late deaths from rupture due to persistent inflammation. Long-term antibiotics have not been mandatory to ensure survival. CONCLUSIONS Mycotic aortic aneurysms of the thoracic and abdominal aorta do benefit from endoluminal repair, particularly when arising in previously normal aortic tissue. Endoluminal grafting also has a role in the palliation of secondarily infected aortas and so to prove its efficacy in the treatment of all these rare cases a registry is required.

Abstract
Intervention is currently reserved in acute aortic dissection for Stanford Type A and for complications of Type B. Endovascular techniques such as fenestration of the intimal flap and stenting of vessel origins have been used to alleviate end-organ ischaemia due to compromised branches. The introduction of stent grafts has offered a realistic alternative to surgery for Type B dissections. Closure of the primary entry tear encourages thrombosis of the false lumen, which is associated with good long-term outcome. Many questions remain unanswered and randomised controlled trials need to be performed to establish the role of stent grafts in uncomplicated Type B dissections, and the use of bare stents to encourage thrombosis of the more distal false lumen. Improvements in the design and engineering of stent grafts may help to establish endoluminal repair as the first line treatment of aortic dissection.

Abstract
Abstract
Background
Symptomatic stenosis of the supra-aortic trunks (subclavian, innominate and common carotid arteries) can be treated by angioplasty/stenting or surgical bypass. The aim of this study was to compare the initial success and outcome of these two types of treatment.
Methods
A prospective database was used to collect information on the presentation, initial success, complications and outcome in 76 patients treated in a single centre between 1983 and 2003.
Results
Thirty-five surgical extra-anatomic bypasses were performed, 13 carotid to carotid, 14 carotid to subclavian, two carotid to axillary, three axillary to axillary, one subclavian to axillary and two subclavian to subclavian. One graft occluded after 19 years. No limbs were amputated and no patient had a stroke. The secondary patency rate was 97 per cent at a mean follow-up of 5 years. Forty-one angioplasties were attempted, 34 of the left subclavian, six of the right subclavian and one of the innominate artery. Angioplasty for six subclavian occlusions was unsuccessful. Twenty-seven of 33 arteries remained patent at a mean follow-up of 4 years after a successful endovascular procedure.
Conclusion
Extra-anatomic bypass for supra-aortic trunk disease has a better patency than angioplasty, with a comparable complication rate.

Abstract
BACKGROUND Thoracic stent grafts offer an alternative to open surgery for thoracic aortic disease, but their long-term durability is unknown. This report includes mid-term follow-up for commercially available thoracic devices. METHODS Data were collected prospectively for a series of endoluminal grafts used to treat thoracic aortic pathology. RESULTS Between July 1997 and October 2002, 67 patients received thoracic stent grafts. Elective procedures incurred a 30-day mortality rate of 2 per cent (one of 42 patients) and urgent repair 16 per cent (four of 25). Paraplegia affected three (4 per cent) of 67 patients and three patients had a stroke. The median follow-up was 17 (range 2-64) months; four patients were lost. There were six late deaths, two from aneurysm rupture (rupture of a mycotic aneurysm at 5 months and stent migration at 28 months). Other device-related complications comprised three proximal endoleaks, one of which required open surgical correction with removal of the stent graft, and two distal endoleaks, which were successfully treated with distal extension cuffs. CONCLUSION In the mid term, endoluminal repair of thoracic aortic pathology appears to be a safe alternative to open surgery, but continued surveillance is essential.

Abstract
INTRODUCTION emergency surgery on the thoracic aorta is associated with a high mortality. Endovascular treatment for these patients may offer a realistic alternative to open surgery. METHOD between 1997 and 2002 data was collected prospectively on all patients who underwent urgent or emergency endoluminal repair for thoracic aortic pathology. All patients had ruptured or were at risk of rupture, and had been assessed as high risk for open surgery. RESULTS twenty-four patients required urgent/emergency stent grafts. The median age was 74 (range 17-90). Indications included: trauma (transection in 3 and traumatic dissection in 1), acute symptomatic type B dissection (4), symptomatic degenerative aneurysms (7), false aneurysms associated with infection (6), Takayasu's vasculitis causing rupture of the descending thoracic aorta (1), symptomatic aneurysm associated with chronic dissection (1) and a secondary aorto-oesophageal fistula (1). The 30-day survival was 83.3% (20/24) and the survival at 1 year was 70.8% (17/24). The median follow-up was 13.5 months (range 2-57). The complications included: transient paraplegia (1), non-disabling stroke (1), distal endoleak treated with an extension cuff (1) and a proximal endoleak (1) which required removal of the graft at open surgery. CONCLUSION endoluminal repair of thoracic aortic disease requiring urgent/emergency treatment has encouraging results with low morbidity and mortality rates compared with open surgery. Long-term follow-up is required to assess the durability of the grafts.

Abstract
Abstract
Background
The Endovascular Aneurysm Repair trial of infrarenal aortic aneurysm repair requires 20 operations to be performed at each centre to eliminate learning curve errors. An analysis was undertaken of the authors' learning curve experience of commercially made thoracic stent grafts.
Methods
Stent grafting was attempted in 26 patients. Aortic pathology included 13 atheromatous aneurysms, six dissections, one coarctation, three false aneurysms and three transections. Successful deployment was performed in 24 patients (92 per cent), but failed in two women due to small iliac arteries. Stent grafts used were Gore Excluder (16 patients), AneuRx (six), Vanguard (one) and Stenford (one). Four patients required two stents, two needed three stents, and 18 had a single stent.
Results
Thirteen elective procedures were uneventful. Two deaths occurred in 11 urgent procedures, from pulmonary embolism and aortic rupture of an unsuspected false aneurysm. The overall in-hospital mortality rate was 8 per cent (two of 24 patients). One graft with a persistent endoleak was removed at open repair at 6 weeks. The subclavian artery origin was covered in three elderly patients, resulting in minor distal ischaemia. No spinal cord problems were seen. One patient died from pneumonia at 8 weeks, and another died from rupture at 28 months as a result of prolapse of the stent into the aneurysm sac.
Conclusion
Assessment of the diameter of the iliac arteries is important, especially in women, to ensure that they accommodate the size of the sheath. Patients with false aneurysms have a poor outcome, and treatment by stent grafting may not be durable. Covering the origin of the left subclavian artery can be undertaken in elderly patients with transient minor symptoms. The use of stent grafts in acute type B dissection should be the subject of a randomized trial. Continued surveillance is essential.

Abstract
Abstract
Background
Open surgical intervention for aneurysms of the distal arch and descending thoracic aorta is associated with high morbidity and mortality rates. Stent grafts offer an attractive alternative treatment for these aneurysms.
Methods
Thirteen patients were treated from July 1997 to August 1999. Eight patients had atheromatous aneurysms; five were elective and three urgent for dysphagia, stridor and back pain. The mean age of these patients was 77 (range 64–90) years. Another five urgent cases comprised transection (two), traumatic dissection (one), acute dissection (one) and secondary aorto-oesophageal fistula (one). The mean age of these patients was 43 (range 18–77) years. The types of stent graft used were Excluder (six), AneuRx (five), Vanguard (one) and Stenford (one). Additional surgical procedures included carotid-to-carotid bypass, exposure of the common iliac artery (as the device was too short to reach the proximal descending thoracic aorta) and repair of a symptomatic infrarenal aortic aneurysm.
Results
One patient with acute aortic dissection 1 month after myocardial infarction died from pulmonary embolus and myocardial reinfarction (mortality rate 8 per cent). One patient who suffered a stroke with good recovery was discharged on day 21 but died from pneumonia at 8 weeks. All aneurysms were excluded on computed tomography apart from the traumatic dissection in which perfusion of the false lumen continued retrogradely. No patient suffered paraplegia or renal failure. No ward patient required admission to the intensive care unit.
Conclusion
Thoracic stent grafts offer a realistic alternative to open surgery, but long-term follow-up is required to assess durability.

PURPOSE To describe a case of secondary aortoesophageal fistula that was treated with an endoluminal stent-graft. CASE REPORT A 58-year-old woman presented with hematemesis and melena. In 1974 she had an interposition graft repair of an aortic transection sustained during a traffic accident. At the examination in 1998, angiography demonstrated a mechanical disruption of the proximal anastomosis forming an aortoesophageal fistula. A 28-mm x 3.75-cm AneuRx stent-graft was introduced via a right femoral arteriotomy and deployed across the defect. Follow-up CT scans at 18 months showed exclusion of the false aneurysm with no evidence of infection; the patient remains well at >2 years after stent-graft implantation. CONCLUSIONS Endoluminal repair can be successful in achieving a satisfactory midterm outcome in cases of secondary aortoesophageal fistula.

Abstract
OBJECTIVES open surgical intervention for aneurysms of the distal arch and descending thoracic aorta is associated with high morbidity and mortality. Stent grafts offer an attractive alternative treatment for these aneurysms. The aim of this study was to assess the morbidity and mortality of endovascular treatment for these aneurysms with stent grafts. DESIGN, PATIENTS AND METHODS a prospective observational study was performed of 37 consecutive patients treated from July 1997 to October 2000 (30 at Guy's and St. Thomas' and 7 at Sheffield). Indications included degenerative aneurysms (n=18), false aneurysm (5), acute dissection (4), aortic transection (4), aneurysm related to previous surgery for coarctation (3), chronic dissection (2) and traumatic dissection (1). Nineteen were performed as elective and 18 as non-elective procedures. RESULTS three non-elective patients died in hospital (in-hospital and 30-day mortality 8%) and one suffered a stroke with spontaneous full recovery. No elective patient died. One patient with a persistent proximal endoleak required conversion to open repair at 6 weeks. Two patients with persistent flow into the sac at 24 h spontaneously thrombosed at subsequent 3 month follow-up. Two further patients developed new distal endoleaks at 3 months and required distal extension cuffs. One patient died at 28 months of aortic rupture. Serial CT scans had shown prolapse of the stent graft into the aneurysm sac and the patient died just before planned endovascular repair. No patient suffered paraplegia or renal failure. Intensive care facilities were only required for patients who needed them preoperatively. CONCLUSIONS thoracic stent grafts can be performed with low morbidity and mortality. They offer a realistic alternative to open surgery. Long term follow up is required to assess their durability.

Abstract
The availability of large diameter stent-grafts is now allowing the endovascular treatment of thoracic aortic aneurysms. Most aneurysms are closely related to the distal arch and it is thus necessary to pass the delivery systems into the arch to effectively cover the proximal neck. Even with extra-stiff guidewires in position, it may still be difficult to achieve this, as a result of tortuosity at the iliac arteries and the aorta. We detail a technique where a stiff guidewire is passed from a brachial entry point through the aorta and out at the femoral arteriotomy site. This allows extra-support and may enable the delivery system to be passed further into the aortic arch than it could with just the regular guidewire position.

Abstract
OBJECTIVES The aim of this study was to develop a scoring system to predict the outcome of long femorocrural and femoropedal bypass grafts performed for critical limb ischaemia. SETTING Teaching hospital. METHODS An analysis of 109 consecutive femorodistal bypass grafts performed for critical lower limb ischaemia between June 1991 to December 1994. Factors shown to affect the outcome were: inflow, number of patent calf vessels, graft material, straight flow to the foot and patent pedal vessels. These variables were weighted according to their relative significance (multivariate Cox regression) and a scoring system (ranging from 0 to 10) was developed. RESULTS Patients with a preoperative score of 0-4 (n = 35) showed a secondary patency of 36% at 1 month, 12% at 3 months and 0% at 10 months (Cum SE = 6.90/0.0). Secondary patency rates for the 46 patients with score 5-7 were 88.7% at 3 months, 56.3% at 12, and 45.1% at 2 and 3 years (Cum SE = 9.82), while the respective values for the 28 patients with score 8-10 were 92.7%, 88.5% and 81.7% (Cum SE = 8.08). The difference was highly significant (p = 0.000) in all tests of equality. In addition, the median total hospital cost was 12,600 Pounds for the group 0-4 compared with 8100 Pounds (group 5-7) and 4400 Pounds (group 8-10) (p = 0.0085). CONCLUSIONS This preoperative scoring system appears to correlate well with the outcome of distal revascularisation to single calf or pedal vessels. If applied to patient selection, it could significantly reduce the total hospital cost per leg saved. A prospective testing of its predictive ability is needed and is in progress.

Abstract
Intraarterial thrombolysis is usually contraindicated after abdominal surgery because of the risk of bleeding. However, it is a highly effective treatment for embolic acute limb ischemia, particularly for clearing the distal vessels. We report a case in which intraarterial thrombolysis was safely used 4 days after laparoscopic cholecystectomy in a patient with an acutely ischemic leg due to embolus.

Abstract
Bilateral uterine artery embolisation was performed to treat eight women with symptomatic large fibroids requiring treatment. Uterine volume was quantitatively assessed by magnetic resonance imaging. Both uterine arteries were occluded effectively in all women, and the procedure was well tolerated, with a 24-36 hour admission for pain relief. The level of pain experienced was variable, but well controlled. Some women experienced intermittent vaginal discharge and pain following the procedure. Improvement of symptoms occurred in six of the seven women and the eighth woman conceived. There were no significant complications. At three months four women had a uterine volume of < 350 cm3. Embolisation appears to be a good alternative to surgery, but longer follow up is required to evaluate the long term effects and to determine those patients for whom the procedure is suitable.

Abstract
OBJECTIVE To assess the success of percutaneous transluminal angioplasty (PTA) in treating infrainguinal graft-related stenoses. DESIGN Retrospective analysis of stenoses undergoing PTA over 6 years. MATERIALS Fifty-seven stenoses in 42 grafts. METHODS Site, length and type of stenoses recorded. Follow-up till discharge, graft occlusion or death. RESULTS PTA was successful in 48/57 stenoses in 36 grafts (G), with a poor result in seven. Further PTA was required in seven stenoses (7 G). One graft occluded at PTA and one stenosis was inaccessible. Overall graft (G) patency (median 13 months) was 82% (1 year patency 84%). Of 48 successful PTAs (37 G), 36 remained patent (28 G), eight (4 G) occluded and four were lost to follow-up (4 G). Fourteen of thirty-six stenoses which remained patent required further intervention (seven PTA, six jump grafts, one vein patch). The four occlusions were associated with small veins (two), multiple stenoses (one) and a PTFE graft which occluded 10 days following PTA. Of the seven PTAs with a poor angiographic result, five remained patent, three after further intervention. CONCLUSION PTA is the best treatment for localised stenoses. Stenoses > 2 cm or multiple (three or more) stenoses are best treated surgically. Follow-up is essential, as 20% require further intervention.

Abstract
Recurrent hyperparathyroidism is rare following transcatheter ablation of mediastinal parathyroid adenomas. When it occurs it is usually early and resistant to further attempts at ablation. We present a patient with primary hyperparathyroidism in whom two surgical attempts at cure had been unsuccessful. Subsequently, a mediastinal adenoma was demonstrated angiographically and embolized with absolute alcohol. Hyperparathyroidism recurred 6 years later and the mediastinal adenoma was subsequently successfully ablated a second time by angiographic embolization with ionic contrast medium.

Abstract
OBJECTIVES There is continued controversy over whether a failed distal bypass influences the level of amputation. This issue is important as the number of arterial bypass grafts undertaken for critical ischaemia is increasing, followed by an increasing number of failed grafts. SETTING Teaching hospital. STUDY DESIGN AND MATERIALS: A prospective analysis of 109 consecutive femorocrural/pedal bypass grafts performed between June 1991 and January 1995 on patients presenting with severe critical lower limb ischaemia (CLI) to a single vascular unit. A further 43 amputations for non-reconstructible distal disease were also analysed. CHIEF OUTCOME MEASURES Mortality, amputation, rehabilitation, survival and knee salvage rates. The Kaplan-Meier method was used for comparison of factors associated with knee preservation. RESULTS Primary amputees had a higher in-hospital mortality (18% vs. 10%) but similar 3 year survival rates (30%) compared with secondary amputees (36.6%). Patients with successful grafts showed a trend towards better survival (61.9% at 3 years) compared to amputees (38.6% at 42 months, p = 0.061). Below- to above-knee amputation ratio was similar in the two groups (0.85 in secondary vs. 0.95 in primary amputees). Factors significantly associated with knee salvage at 3 years were shown to be: the condition of the inflow (81.9% for good vs. 43.1% for impaired, p = 0.000) the state of the profunda femoris artery (good 93%, impaired 71%, occluded 37% p = 0.0001) and the graft material (vein 81.8% vs. PTFE 59.8%, p = 0.033). The presence of tissue loss (p = 0.0523) and secondary procedures (p = 0.0879) showed a trend to become significant. Multivariate and Cox regression analysis showed that the most important factors were the inflow (p = 0.001), the state of the profunda (p = 0.001), the graft material (p = 0.034) and previous revascularisation attempts (p = 0.019). CONCLUSIONS The factors which determine knee loss are a compromised inflow state, the presence of an inadequate profunda femoris, previous revascularisation attempts and the use of synthetic graft material. Most of these factors (with the exception of infection related to revascularisation) are present before reconstructive arterial surgery is performed and this study shows that failure of a distal graft does not affect the final amputation level.

Abstract
BACKGROUND The past decade has seen an increase in the use of distal arterial bypass grafts for treating critical lower limb ischaemia. However, this surgical policy is associated with variable results. The aims of this study were to identify factors that affect outcome and to calculate the cost of such surgical interventions. METHODS A prospective analysis of femorocrural and femoropedal bypass grafts and primary amputations was performed between June 1991 and January 1995. A consecutive series of 109 limbs with critical lower limb ischaemia underwent a bypass graft to a single crural or pedal vessel shown on either preoperative intra-arterial digital subtraction angiography or at surgical exploration. Complete data were available for all patients during follow-up which ranged from 0 to 42 (median 12) months. The factors assessed were age, sex, diabetes, pedal arch, graft material, outflow vessel, number of calf vessels, number of vessels crossing the ankle, inflow state, previous revascularization procedures and foot gangrene and tissue necrosis. Chief outcome measures were survival, knee and limb salvage, patency rates and hospital cost. The Kaplan-Meier method was used to construct life tables and the log rank test for comparison of factors. Cost was measured according to National Health Service criteria, and comparisons were made by the Mann-Whitney U test. RESULTS At 36 months primary patency was 27 per cent, primary assisted patency 31 per cent and secondary patency 45 per cent; limb salvage was 54 per cent, knee salvage 73 per cent and survival 58 per cent. Significant factors in predicting outcome were graft material (P = 0.004), inflow state (P = 0.0001), number of calf vessels (P = 0.039), number of vessels crossing the ankle (P < 0.0001) and the condition of pedal vessels (P < 0.0001). Cost analysis showed that the median price for a successful bypass was 4320 pounds, that of a failed bypass leading to amputation 17,066 pounds and that of primary amputation in patients with non-reconstructable distal disease 12,730 pounds. CONCLUSION The patency rate of femorotibial and peroneal bypass depends on the inflow state, the availability of a venous conduit, the number of calf vessels, the presence of straight flow to the foot and the presence of patent pedal vessels. These factors can help in the selection of patients for femorodistal reconstruction and may explain the wide variation in published results. The low cost of revascularization compared with amputation justifies attempted reconstruction. However, repeated attempts to reconstruct patients with severe distal disease who may benefit more from primary amputation will significantly increase the cost.

Abstract
We describe an arteriovenous fistula (AVF) at the site of balloon dilatation immediately after percutaneous transluminal angioplasty (PTA) of the femoropopliteal artery. This occurred during an otherwise uncomplicated angioplasty with a good clinical result. The AVF closed spontaneously within 2 months as monitored by color duplex ultrasound. This uncommon complication of PTA is not widely recognized.
