Abstract
OBJECTIVE A suitable ipsilateral great saphenous vein (GSV) autograft is widely considered the best material for arterial reconstruction of a popliteal artery aneurysm (PAA). There are, however, cases in which such a GSV is absent, diseased, or of too small diameter for this use. Alternatives to GSV are synthetic conduits, but with a reduced long-term patency, in particular for infragenicular bypass; other venous autografts of marginal use; and stent grafts still in the first stages of their evaluation. However, a sufficiently long segment of the ipsilateral superficial femoral artery (SFA) is often preserved in patients with a PAA. Such a segment may be used as an autograft for popliteal reconstruction. Moreover, the morphometric characteristics of the SFA often optimally match those of the distal native popliteal bifurcation. SFA autografts (SFAAs) have therefore become our choice when the ipsilateral GSV is not suitable. We herein present the long-term results of SFAA for the treatment of PAA in the absence of a suitable GSV. METHODS Within this single-center study, all cases during the last 26 years were retrospectively reviewed. Demographics, risk factors, comorbidities, morphometrics of the PAA, and preoperative and follow-up data were intentionally sought. RESULTS From 1997 to 2017, there were 67 PAAs treated with an SFAA. The mean age of the patients was 67.67 ± 12 years, and 98% were male. Symptoms included intermittent claudication in 25% (17), critical limb ischemia in 7% (5), and acute ischemia in 10% (7) of the patients; 51% (34) of the patients were asymptomatic. The mean aneurysm diameter of the treated PAA was 29 ± 11 mm (12-61 mm). The mean operative time was 254.8 ± 65.6 minutes (140-480 minutes), with a mean cross-clamp time of 64.5 ± 39 minutes (19-240 minutes). The median length of stay was 9 ± 6.4 days (5-42 days). There were no early amputations or deaths in the series. During a mean follow-up of 47.91 ± 48.23 months, there were 2 anastomotic stenoses, 11 thromboses, 1 infection, and 1 aneurysmal degeneration of the graft; 6 patients died of unrelated causes. The 1-, 3-, 5-, and 10-year primary and secondary patency rates were 93% and 96%, 85% and 90%, 78% and 87%, and 56% and 87%, respectively. CONCLUSIONS These data suggest that SFAA use to treat PAA is a safe and durable option. A prospective and comparative work is necessary to confirm these results and to determine the interest of this technique as a first-line strategy.

Abstract
OBJECTIVE Most patients requiring vascular surgical reconstruction are at high risk for major morbidity and mortality, with certain vascular procedures at particularly high risk for complications. Although numerous comorbid conditions are precisely the risk factors that determine outcome, we review particular factors for each surgery that may be optimized to alter outcome and minimize postoperative complications. DESIGN Literature review. RESULTS Certain aspects of care are common to all vascular surgery procedures, including thoracoabdominal aortic aneurysm repair, pararenal and ruptured abdominal aortic aneurysm repair, mesenteric and renal revascularization, and carotid endarterectomy. Some factors that are important include careful preoperative assessment and optimization of cardiac, pulmonary, and renal function and volume status. In addition, the use of experienced teams during and after the procedure, as well as clear and continuous communication between all surgical team members, may improve outcome. Particular attention to procedural details is also crucial to achieving excellent results. CONCLUSIONS Patients needing vascular surgery often possess management challenges that increase the risk of perioperative complications. Meticulous attention to details during all phases of care, including preoperative optimization as well as intraoperative procedural conduct and communication, helps achieve optimal results and thus minimize the risk of complications.

Abstract
Although the treatment of atherosclerotic renal artery stenosis with use of percutaneous angioplasty, stent placement, and surgical revascularization has gained widespread use, there exist few prospective randomized controlled trials (RCTs) comparing these techniques to each other or against the standard of medical management alone. To facilitate this process as well as help answer many important questions regarding the appropriate application of renal revascularization, well-designed and rigorously conducted trials are needed. These trials must have clearly defined goals and must be sufficiently sized and performed so as to withstand intensive outcomes assessment. Toward this end, this document provides guidelines and definitions for the design, conduct, evaluation, and reporting of renal artery revascularization RCTs. In addition, areas of critically necessary renal artery revascularization investigation are identified. It is hoped that this information will be valuable to the investigator wishing to conduct research in this important area.

Abstract
Renovascular hypertension represents a form of correctable hypertension and preventable renal failure. Such patients need to be identified early so that specific therapy can be instigated. Patient identification requires a high index of suspicion in patients with certain clinical features. Subsequent non-invasive imaging may result in angiography which is required for diagnostic purposes and for planning intervention. Correctable therapy takes one of two forms, namely percutaneous transluminal renal angioplasty, with or without stenting, or surgical revascularisation, together with modification of underlying risk factors.

Abstract
PURPOSE To determine whether gadodiamide is a safe and useful angiographic contrast agent for help in diagnosis and percutaneous treatment of renal artery stenosis in patients with renal insufficiency. MATERIALS AND METHODS Diagnostic renal angiography and percutaneous renal interventions were performed by using gadodiamide (total dose, 0.3 mmol/kg) and CO2 as intraarterial contrast agents in 25 procedures in 24 patients with renal insufficiency. Serum creatinine levels were obtained within 24 hours before and at 24 and 48 hours after the procedure. Increases in serum creatinine of more than 44 mumol/L were considered clinically important. Gadodiamide-enhanced angiograms were compared with CO2-enhanced angiograms. RESULTS In 23 (92%) of 25 procedures, there was no increase in serum creatinine level at 48 hours. One patient with acute and chronic rejection of a renal transplant and one with evidence of cholesterol embolization had a clinically important increase in serum creatinine level at 48 hours. No marked increase in creatinine level was observed in patients with relatively low baseline levels (n = 19). Gadodiamide-enhanced angiograms appeared to be better than CO2-enhanced angiograms for help in identifying renal artery occlusions, visualizing renal vessels incompletely filled with CO2, and determining the progress of intervention. CONCLUSION Gadodiamide appears to be a safe and useful intraarterial contrast agent in patients with renal insufficiency and can be used to supplement or confirm CO2-enhanced angiographic findings.

Abstract
Ischemic renal disease (IRD) is defined as a clinically important reduction in glomerular filtration rate or loss of renal parenchyma caused by hemodynamically significant renal artery stenosis. IRD is a common and often overlooked clinical entity that presents itself in the setting of extrarenal arteriosclerotic vascular disease in older individuals with azotemia. Eleven to 14% of end-stage renal disease (ESRD) cases are attributable to chronic IRD. A high percentage of patients entering ESRD programs are hypertensive. Many patients with a presumed diagnosis of hypertensive nephrosclerosis actually have undiagnosed ischemic nephropathy as the etiology of their ESRD. It is important for the clinician to identify IRD, because IRD is a potentially reversible cause of chronic renal failure in a hypertensive patient. Atherosclerotic renal artery disease is common among patients with coronary artery disease and aortic and peripheral vascular disease. Atherosclerotic renal artery disease is a progressive disorder, and its progression is associated with loss of renal mass and functioning. A decrease in glomerular filtration rate sufficient to cause an elevation of the serum creatinine concentration requires injury to both kidneys. Consequently, IRD can arise from one of two main clinical situations: bilateral hemodynamically significant renal artery stenosis leading to bilateral renal ischemia; and hemodynamically significant renal artery stenosis in a solitary functioning kidney, or in a kidney that is providing the majority of a patient's glomerular filtration. The primary reason for establishing the diagnosis of IRD is the hope that correction of a renal artery stenosis will lead to improvement of renal function, or a delay in progression to ESRD. There are six major clinical settings in which the clinician could suspect IRD: acute renal failure caused by the treatment of hypertension, especially with angiotensin converting enzyme inhibitors; progressive azotemia in a patient with known renovascular hypertension; acute pulmonary edema superimposed upon poorly controlled hypertension and renal failure; progressive azotemia in an elderly patient with refractory or severe hypertension; progressive azotemia in an elderly patient with evidence of atherosclerotic disease; and unexplained progressive azotemia in an elderly patient. Noninvasive testing modalities that have been used recently include the angiotensin converting enzyme inhibitor renal scan, duplex Doppler sonography, magnetic resonance angiography, and the spiral computed tomography. Treatment methods include percutaneous transluminal angioplasty, endovascular stenting, and surgical revascularization. The results of treatment for preservation of renal function have been encouraging, with stabilization or improvement in renal function observed in a significant proportion of cases.

Abstract
Over the past decade, ischemic nephropathy has gained recognition as a distinct and treatable clinical entity. Atherosclerotic renal artery stenosis is the leading cause of ischemic renal disease. Among the aging population entering renal replacement programs, both renal artery and systemic atherosclerosis are common. Over recent years, patients with ischemic renal disease are presenting later and have diffuse atherosclerosis and other comorbid conditions. Improved screening techniques, patient selection, and interventional approaches have resulted in better outcomes in most centers. Percutaneous transluminal renal angioplasty has emerged as the treatment of choice in some centers for nonostial renal artery stenosis. Both percutaneous transluminal renal angioplasty and surgical repair have proven beneficial for renal function salvage. Many studies have elegantly demonstrated the pathophysiologic consequences of acute ischemia to the kidney. The concepts derived from acute studies have served as a springboard for considering the adaptive and maladaptive renal responses to chronic ischemia.

Abstract
This report describes the clinical course, diagnostic evaluation and management of six children with bilateral renal artery stenosis (RAS) and concurrent narrowing of the abdominal aorta. Except for one child with active arteritis, the others were asymptomatic. There were no clinical or laboratory features suggesting the etiology of hypertension in four of six patients, and diagnostic procedures, including Doppler duplex ultrasound and captopril scintigraphy, were unreliable in screening for such hypertension. Abdominal aortography and selective renal angiography confirmed the diagnosis of bilateral RAS and associated anatomical alterations of the aorta and its branches. The hypertension was severe and minimally responsive to antihypertensive agents. It was cured or improved after percutaneous transluminal angioplasty (PTA) of three vessels in two children with mid-vessel stenoses, while hypertension persisted after PTA of two mid-vessel stenoses in a third child and one vessel with ostium stenosis in a fourth child. Autotransplantation of seven kidneys in four children resulted in cure of significant improvement of the hypertension. Renal function was preserved in all children during a mean follow-up time of 41 months. Based on illustrative data from these six children, as well as information from a review of the literature, this report discusses the key diagnostic issues and stresses the potential advantages of renal autotransplantation in selected children with this disorder.

Abstract
PURPOSE Thoracic aortorenal bypass is a new technique for surgical renal revascularization in patients with severe atherosclerosis of the abdominal aorta. In such cases, the thoracic aorta is often free of disease. METHODS From 1989 to 1992, thoracic aortorenal bypass was performed in 23 patients with hypertension, abdominal aortic atherosclerosis, and celiac artery stenosis; in 21 patients, renal artery stenosis was present bilaterally or in a solitary kidney. RESULTS There was one operative death. Among the remaining 22 patients, hypertension was cured or improved after operation in 19 (86%), and renal function was improved or stable in 21 (95%). CONCLUSIONS Thoracic aortorenal bypass has several advantages and is a useful alternative to abdominal aortic replacement in selected older patients who require renal arterial reconstruction.

Abstract
The management of patients with renal artery disease has changed in recent years. This has occurred due to the advent of PTA as an effective method of treatment for certain patients, an enhanced appreciation of advanced atherosclerotic renal artery disease as a correctable cause of renal failure, and improved results of surgical revascularisation in both older patients with severe aortic atherosclerosis and younger patients with branch renal artery disease. PTA currently yields excellent results and is the treatment of choice for patients with fibrous dysplasia of the main renal artery and non-ostial atherosclerotic lesions. Most reports in the literature indicate that surgical revascularisation provides more effective therapy for patients with ostial atherosclerotic lesions. Surgical revascularisation also remains the treatment of choice for the majority of patients with branch renal artery disease, a renal artery aneurysm, renal artery occlusion, and recurrent renal artery stenosis after failed PTA or surgery. Excellent clinical results can be achieved with both PTA and surgical revascularisation in properly selected patients.

Abstract
Since 1981, eight children have been treated at this hospital for hypertension due to bilateral renal artery stenosis (RAS). Useful diagnostic studies were DTPA renal scan following pretreatment with captopril, and selective renal angiography. All patients underwent attempted surgical revascularization of the RAS and three had aortoaortic bypass of an abdominal aortic narrowing. Of the 14 kidneys that had repair of RAS, a successful outcome was obtained in 11 (80%). Three patients required unilateral nephrectomy. Five of eight patients are normotensive and off all medications, and three are normotensive on reduced medication doses.

Abstract
Between January 1979 and December 1986, a total of 74 renal revascularizations were performed in 68 patients using the reinforced expanded polytetrafluoroethylene prosthetic graft. These 74 revascularizations represent 29% of 251 surgical renal revascularizations performed during the same period of time. Eight patients had a total of nine revascularizations in the emergency setting (group I) for ruptured suprarenal aneurysm or acute thrombosis of the renal arteries. Only one patient survived and six years later, his anatomic and functional results are satisfactory. Sixty-five revascularizations were performed electively in 60 patients (group II). This group consisted of 19 renal revascularizations alone, and 46 combined aortic and renal revascularizations. One patient died of respiratory complications two months after operation after his thoracoabdominal aneurysm was cured. Early repeat postoperative arteriography showed that six reconstructions had occluded (three major renal arteries, three polar arteries). One patient was lost to follow-up. The remaining patients were followed for a mean of 41 months. Follow-up arteriograms obtained during 1987 showed that there were two late occlusions and two distal anastomotic stenoses. Actuarial patency was 85 +/- 10% at 72 months. Polytetrafluoroethylene prosthetic grafts constitute a reliable material for renal revascularization and combined aortic and renal reconstruction in certain anatomic conditions.
