Abstract
In a retrospective analysis of 125 patients and a prospective evaluation of 83 patients with terminal uremia undergoing kidney transplantation, juvenile diabetes mellitus was found to be a significant risk factor for the development of postoperative thromboembolism. We found a high frequency of objectively verified thromboembolism despite the relatively young age of the patients. Besides diabetes, no other clinical risk factor differed between patients with and without thrombosis.

Abstract
Seventy-two patients, aged 6-69 years, were operated on because of presumed renovascular hypertension and subjected to follow-up studies for 4-60 months (mean 28). Unilateral renal artery stenosis was present in 47 patients. Surgery was followed by normalization of blood pressure (BP) in 28 and improvement in 7, whereas 12 showed no response. Sixteen were below the age of 40 and only one failed to respond to surgery. Peripheral venous plasma renin activity (PRA) was increased in 32 and urinary aldosterone elevated in 22 of 35 patients responding favourably to surgery. Renal vein PRA was higher from the kidney with the stenotic renal artery as compared to the contralateral side in all patients responding to surgery. Preoperative peripheral PRA difference was also found in 7 of 12 patients not responding to surgery. Preoperative peripheral PRA was increased in 26 of the patients becoming normotensive after surgery. In 20 of these patients normalization of BP was associated with a fall in peripheral PR. Twenty-five patients had bilateral renal artery stenosis. Four of them had severe hypertension, renal insufficiency and generalized atherosclerosis. They died in immediate connection with operation. Unilateral operation, performed in 11 of the remaining 21 patients, was followed by normalization of BP in 3 and no response in 8. Bilateral reconstructive surgery, performed in 10 patients, resulted in normotension in 2 and improvement in 7. Our studies indicate that determination of peripheral PRA and/or urinary aldosterone can serve as a useful prognostic indicator after surgery in hypertensive patients with renal artery stenosis.

Abstract
Coarctation of the abdominal aorta as a congenital disease is infrequent, the diagnosis mostly being made at an early age because of renovascular hypertension. Patients who reach the age of 40 more often tend to have the problems located distally to the renal arteries. A 66-year-old female is described, who developed an aortic occlusion, renovascular hypertension and uremia. She was cured with a bifurcation graft and a patch angioplasty of a stenotic renal artery and nephrectomy of the contralateral kidney with an occluded artery without refilling. A literature survey is made of patients older than 40 years.

Abstract
We have found 3 reports of fibromuscular hyperplasia (FMH) of the renal arteries with hypertension occurring in 2 siblings as well as a few instances of renal agenesis and unilateral renal aplasia occurring in the same family. In this paper we report on FMH of the renal arteries in 2 women, one giving birth to a child with renal agenesis, the other to a child with a focally dysplastic hypoplasia of the kidneys. A third family is reported, heavily loaded with hypertension and otosclerosis, in which 2 siblings with FMH and otosclerosis were found. Another 4 patients without known heredity for hypertension, but with FMH combined with renal or urinary tract anomalies, are also reported. The findings are discussed, particularly in relation to the findings in a large material of chronic non-obstructive pyelonephritis, where in those with well maintained renal function, hypertension below the age of 40 was found predominantly in females with a positive family history of hypertension and signs highly suggestive of infected hypoplasia or dysplasia of the kidney.

Abstract
Jean Martin Charcot was the first to give a detailed description of intermittent claudication, and a correct interpretation of the mechanism behind the symptoms. He borrowed the name of the syndrome from the veterinarian literature, where it had been described to occur in horses, and caused by inflammatory changes in aorta at the origin of the large vessels to the extremities. The case presented by Charcot was a man with a traumatic pseudoaneurysm in his common iliac artery. He had in addition an arterio-enteric fistula, a condition which probably had not been described before.

Abstract
OBJECTIVES To study renal function in patients with aortocaval fistula, before and after surgery. DESIGN Retrospective study. MATERIAL AND METHODS During the last 22 years nine male patients (median age 67, age range 50-72) with spontaneous aortocaval fistula in combination with AAA were operated upon. This constitutes 4% of the patients with ruptured AAA and 1.5% of all patients with AAA. RESULTS A preoperative diagnosis of aortocaval fistula was established in three of the nine cases. The medium duration of symptoms prior to surgery was 5 days (range 4 h-14 days). The fistula was combined with an extravasating ruptured AAA in only three patients. Seven of the patients had acute renal insufficiency, with creatinine levels of in median 292 mumol (IQR 218-342). Creatinine declined to 172 mumol/l (IQR 170-313) on the fifth postoperative day in uncomplicated cases and to 86 mumol at discharge. One patient died due to multi-organ failure, whereas the other left hospital well and alive with normal renal function. CONCLUSION Acute preoperative renal insufficiency due to an aortocaval fistula in patients with AAA is often due to venous congestion, and is normalised after successful surgery.

Abstract
Deep venous thrombosis continues to be a frequent complication of surgery and trauma. The topic is controversial with regard to diagnosis, indication for prophylaxis, and suitable methods for prophylaxis and therapy. We review some of the highlights of the extensive literature in this field during the last few years. Particular emphasis is given to new trends in diagnostic methods, newly discovered genetic factors for thrombophilia, and the use of heparins for prophylaxis and therapy of thromboembolic disease.

Abstract
OBJECTIVES To define current practice regarding the use of pharmacological prophylaxis to prevent postoperative graft occlusion. DESIGN Prospective open questionnaire. MATERIALS AND METHODS Questionnaires regarding this subject were sent to vascular surgeons throughout the world to analyse current practice. RESULTS 651 questionnaires were returned with a response rate of 62% and form the basis for this report. Data from 100,334 vascular reconstructions were reported in this survey. Prophylaxis against postoperative graft occlusions was common. Treatment periods were usually greater than 1 year. Among carotid surgery patients, 82% received prophylaxis, consisting mainly of low-dose acetysalicylic acid (ASA). In Mid-Europe the use of oral anticoagulation was more common than in other regions (p < 0.001). Among aneurysm surgery patients, 38% received prophylaxis. For infrainguinal bypass, ASA in low dose was the most commonly used agent worldwide. However, oral anticoagulation was more frequent in Mid-Europe, in contrast to South America where the combination of ASA and dipyridamole was most common. Considerable geographical differences regarding patient selection, the frequency of specific procedures and operative techniques existed. CONCLUSIONS Important world-wide differences exist regarding prophylaxis for postoperative graft occlusion.

Abstract
It was the intent of this study to document, in general, the patterns and complications of heparin and protamine usage during carotid endarterectomy, aortic and femoral-popliteal-tibial reconstructions for occlusive disease, elective and emergent abdominal aortic aneurysmectomy, thromboembolectomy, and dialysis arteriovenous (AV) fistula placement by surgeons from North America and Europe. All vascular surgeons from the Society for Vascular Surgery (SVS) and the European Society for Vascular Surgery (ESVS) were surveyed by a voluntary, self-reported questionnaire. Six hundred and forty-six completed questionnaires (284 from SVS and 362 from ESVS), representing a 62% response rate, were returned for evaluation. Systemic and regional administration of heparin was common during vascular procedures performed by both SVS and ESVS surgeons. Use of protamine to reverse heparin anticoagulation varied among SVS and ESVS surgeons, respectively, during: carotid endarterectomy (54% vs. 26%, p < 0.01), elective aortic reconstruction for occlusive disease (58% vs. 23%, p < 0.001), elective aortic reconstruction for abdominal aortic aneurysm (63% vs. 27%, p < 0.001), and femoral-popliteal-tibial reconstruction (44% vs. 15%, p < 0.001). Adverse reactions to protamine among the 25,219 and 12,902 cases reported from SVS and ESVS surgeons, respectively, included: hypotension (1209 and 495 cases), pulmonary artery hypertension (65 and eight cases), anaphylaxis (52 and 10 cases), and death (seven and two cases). These adverse responses accounted for 5.3% and 4.0% of the SVS and ESVS cases, respectively. Although this study is subject to the known limitations of a retrospective survey, it is clear that heparin use is common. Protamine reversal of heparin anticoagulation is more common in North America.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Arterial reconstructive surgery for upper limb ischaemia of non-traumatic non-embolic origin is uncommon in comparison to that of the lower extremities and long-term follow-ups are rare. Forty-eight patients (27 females, 21 males) with a median age of 58 years (range 22-88) were retrospectively analysed for risk factors, survival and patency rates. Seventy-three per cent were smokers, 42% had hypertension and 33% had had previous vascular interventions. Diabetes was only seen in 4% of the cases. Effort fatigue was the dominant cause for surgery followed by micro-embolism and rest pain or gangrene. The left side was more frequently affected with 30 procedures compared to 18 on the right. Bypass with either Dacron, ePTFE or autologous vein was the most frequent procedure in 56% of the cases followed by thrombendarterectomy (23%) and subclavio-carotid transposition (11%). Arm-arm index rose from 0.63 (SD 0.28) preoperatively to 1.02 (SD 0.12) after 1 month and at the end of follow-up (median 75 months) it was 0.96 (SD 0.15). Cumulative survival rates were at 1 month 98%, 1 year 91%, 5 years 81% and at 10 years 73%. Cumulative primary patency rates at the same intervals were 96, 96, 88 and 80%, respectively. Thus the survival rate and patency rate are favourable in comparison with arterial surgical procedures of the lower extremity.

Abstract
PURPOSE The purpose of this prospective randomized study was to compare percutaneous transluminal renal angioplasty (PTRA) and operation as initial therapy with regard to technical results, primary and secondary patency, and effects on blood pressure and renal function in patients with atherosclerotic unilateral renal artery stenosis. METHODS Fifty-eight patients who did not have diabetes, who were less than 70 years of age, and who had severe hypertension and significant stenosis were randomized to receive PTRA or operation. Angiography was performed 10 days, 1 year, and 2 years after treatment to verify patency, and blood pressure and renal function were simultaneously evaluated. RESULTS Technically, PTRA was successful in 83% and operation in 97% of patients. The primary patency rate after 24 months was 75% in the PTRA group and 96% in the operative group in technically successful cases. The secondary patency rate in the PTRA group was 90% and in the surgical group 97%. To achieve these results four patients in the PTRA group required operation, and one patient in the surgical group required PTRA. Hypertension was cured or improved after additional treatment in 90% of the patients after PTRA and 86% after operation. The corresponding figures for improved or unchanged renal function were 83% and 72%, respectively. After additional treatment, effects on blood pressure and renal function did not differ. Seventeen percent of the patients treated with PTRA required surgical intervention. CONCLUSIONS PTRA is recommended as first choice of therapy for atherosclerotic renal artery stenosis causing renovascular hypertension if combined with intensive follow-up and aggressive reintervention.

The aim of this study was to investigate the long-term results of percutaneous transluminal angioplasty of atherosclerotic renal artery stenosis (PTRA) in patients with renovascular hypertension with or without impending renal insufficiency who were followed up intensively with aggressive reintervention. Diagnostic work-up was based on angiography, pressure gradient and renal venous renin measurement. Patients were scheduled for regular follow-up after the PTRA and a deterioration in blood pressure or renal function was an indication for re-evaluation, and reintervention if necessary. Sixty-five patients had 71 renal artery stenoses where PTRA was attempted. It was technically successful in 59 stenoses and two occlusions and failed in ten (14%). At the end of follow-up (median 56 months [2-99]), the primary patency rate was 55%, 27 had restenosed and four were occluded, all but two within 12 months. Seventeen were treated by a further PTRA and eight by surgical reconstruction. At the end of follow-up the secondary patency after all interventions was 90%. One patient died 1 month after PTRA, and at the end of follow-up 21 patients (32%) had died, most of them (80%) from cardiovascular disease. Multivariate analyses showed a significantly reduced survival rate in patients with multiocular atherosclerosis, renal insufficiency, contralateral renal artery stenosis and ischaemic heart disease. At the end of follow-up 90% of the patients were cured or improved with regard to blood pressure. In patients with impending renal insufficiency renal function was improved in 50% and unchanged in 39%. With this strategy 55% of the patients needed only one treatment with PTRA, 25% needed a re-PTRA and 20% had to be operated on. PTRA can be recommended as initial treatment of atherosclerotic renal artery stenosis provided intensive follow-up and aggressive reintervention are performed when indicated.

Abstract
Clinical outcome and health care costs related to investigation, treatment with either percutaneous transluminal renal angioplasty (PTRA) or reconstructive surgery, and follow-up of patients with renovascular hypertension with or without uraemia were analysed in 21 PTRA-treated and 16 operated patients. Most renal artery stenoses were atherosclerotic. Nineteen PTRAs were successful or partly successful and two failed; the patients were operated on without delay. All surgical reconstructions were successful. In the PTRA group six restenoses occurred after 4-24 months. Four were treated with re-PTRA and two were operated on. No recurrence occurred in the operated group. At the end of follow-up (median 48, range 9-84 months) primary patency in the PTRA group was 69 per cent and in the operated group 100 per cent. Secondary patency in the PTRA group was 100 per cent. With regard to hypertension, including primary and secondary results, 19 out of 21 (90 per cent) patients were improved in the PTRA group and 13 out of 16 (81 per cent) in the operated group. The diagnostic and preprocedure costs were the same in both groups, whereas the procedure and postprocedure costs were lower in the PTRA group. However, the follow-up costs were considerably higher because of recurrences and their treatment in the PTRA group. The total median cost of reconstructive surgery was 12 per cent higher than for PTRA, a non-significant difference.

Abstract
In the article we discuss our experience in dealing with visceral aneurysms at Malmö General Hospital during the period, 1971-85. Of the total of 25 patients diagnosed, eight had ruptured aneurysms, six underwent elective surgery, and 11 underwent no surgical intervention. Of the aneurysms found, nine were of the splenic artery, five of the superior mesenteric artery and its branches, three of the pancreaticoduodenal artery, two of the celiac artery, and one of the gastroduodenal artery. There was no mortality either among patients undergoing surgery, or from complications among those treated conservatively without surgery.

Abstract
A wide range of clinical symptoms and signs are observed with venous thrombosis. Nonetheless, clinical diagnosis has been found to be unreliable and accurate diagnostic methods must be used before potent therapy such as anticoagulation is instituted, since the complications of treatment themselves can be life-threatening. Phlebography is still the basic reference for evaluation of deep venous disease. While it is felt to be the most accurate, there are still limitations relative to difficulty in separating acute from chronic disease, and in obtaining adequate contrast in certain veins such as calf muscles and in the larger intraabdominal veins. Moreover, it is an uncomfortable invasive test, not without complications of its own. The 125I-fibrinogen uptake test is an excellent test for screening for forming thrombi. The sensitivity of this test is high, particularly in the detection of small calf vein thrombi. The primary drawbacks of this technique are that it is falsely positive in cases where there has been bleeding, inflammation, gross edema, arthritis, or leg ulceration. It is not accurate above mid-thigh because of the high blood flow at the level of the groin and pelvis. Radioactive labeled plasmin which will adhere to the surface of recently formed thrombi can also be used for diagnosis. The limitations are a very short half-life of the radioactive label so that repeated investigation of a patient cannot be performed unless new injections are given. The diagnostic accuracy is comparable to that of radioactive labeled fibrinogen and has the same advantages and disadvantages. Plethysmographic techniques have been used with various modifications.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Twenty-four patients, with an occluded renal artery diagnosed at angiography or operation, in whom previous angiography had demonstrated an atherosclerotic renal artery stenosis, were compared with a group of patients with a renal artery stenosis that remained patent after a similar interval. The risk of occlusion was found to increase with age, the degree of stenosis and advanced generalised atherosclerosis. At the presumed time of occlusion few patients had symptoms which when present were vague and easily overlooked. The most suggestive sign of occlusion was a rise in serum creatinine which was seen in the majority of the patients.

Abstract
We report a rare case of chyluria in a patient from an area not endemic to filariasis. Initial surgical treatment consisted of stripping of the renal pedicle, following which the patient was free of symptoms for 3 months. Recurrence was noted and renal autotransplantation was performed. Chyluria has not recurred 12 months after the second operation. The etiology and various treatments of chyluria are discussed.

Abstract
Solitary iliac artery aneurysms are rare, and most reports have been presented as case reports. By combining autopsy records and operating records, a total of 13 cases were found: during a 15-year period (1971 to 1985), 42,010 of the inhabitants of Malmö died (population 230,000) and 35,265 (including 9014 forensic autopsies) underwent autopsy (84%). Solitary iliac artery aneurysms were found in seven (0.03%) of the 26,251 patients who underwent autopsy at the hospital; six of those had been asymptomatic and one was ruptured. Among the 9014 persons who underwent forensic medical autopsy, there were two with ruptured solitary iliac artery aneurysms. Four patients had clinically detected solitary iliac artery aneurysms, three of which were ruptured. All patients underwent surgery, and two of the three patients with ruptured solitary iliac artery aneurysms left the hospital well. The rupture rate of iliac aneurysm among those found at autopsy was one of seven (14%) and among those clinically detected three of four.
