Abdominal Aortic Aneurysm Repair Requiring Left-Sided Inferior Vena Cava Interposition.

Background: Left-sided inferior vena cava (IVC) is a rare congenital venous anomaly. We describe a case of open repair of a nonruptured abdominal aortic aneurysm (AAA) in a patient with left-sided inferior vena cava requiring IVC transection and reconstruction with interposition graft.

Case Report: A 56-year-old man presented for elective repair of a 6.

Technical complications of endovascular abdominal aortic aneurysm repair.

Purpose: Results from 34 endovascular repairs of abdominal aortic aneurysms are reviewed to identify technical complications and relate them to anatomic and technical features of the operation.

Methods: Twenty-one patients underwent attempted tube graft repair (mean follow-up, 13 months). Thirteen patients underwent placement of a bifurcated graft (mean follow-up, 7.

Limb ischemia: surgical therapy in acute arterial occlusion.

Mortality and amputation rates from acute arterial occlusion are reported from 7 to 37 per cent and 10 to 30 per cent, respectively. Recent data from thrombolysis or peripheral arterial surgery suggest no significant differences between initial management with surgical or thrombolytic therapy. Mortality and amputation rates were in the above ranges.

Resource utilization and pathways: meeting the challenge of cost containment.

The 1990s will bring sweeping changes with managed care and capitation. To address this cost/quality paradox, selective intensive care utilization is coupled with clinical pathways as an innovative change for all patients having cerebral revascularization (CVR) or femoral revascularization (FR). From January 1, 1991 through June 30, 1995, data were accumulated on 2023 procedures in 1524 patients.

Case management in cerebral revascularization.

Purpose: We examined the clinical and financial outcomes of case management coupled with the initiation of selective use of the intensive care unit (ICU) in all cerebral revascularization procedures.

Methods: Three hundred eighty-four procedures in 331 patients were retrospectively reviewed. Morbidity and mortality rates, hospital length of stay, cost, and ICU or hospital readmissions were examined.

Subclavian revascularization. A quarter century experience.

Objective: Twenty-five years of experience with subclavian revascularizations were reviewed to determine the long-term patency rates of different extrathoracic approaches.

Summary Background Data: Although it is generally agreed that proximal subclavian stenosis should be treated by an extrathoracic route whenever possible, the optimum procedure is debated. Alternatives include subclavian carotid bypass, subclavian-to-subclavian or axillo-axillary bypasses, and the authors' preferred technique of subclavian carotid transposition (SCT).

Cryopreserved saphenous vein allografts for below-knee lower extremity revascularization.

Objective: Cryopreserved saphenous vein allografts have been offered as an alternative conduit for bypass in ischemic limbs. The authors examined the efficacy of this conduit for arterial bypass to the distal popliteal and tibial arteries in patients in whom autogenous vein was not available.

Summary Background Data: Previous experience with arterial and venous allografts has been unsatisfactory because of aneurysmal degeneration and poor patency.

Oral management of a patient with a plasminogen activator inhibitor (PAI-1) deficiency: case report.

Plasminogen activator inhibitor-1 (PAI-1) deficiency causes a rare bleeding disorder by allowing excessive fibrinolysis to occur. Knowledge of the specific type and severity of the bleeding disorder is crucial in planning a safe and appropriate treatment sequence in conjunction with a hemophilia team. This article reports the oral management of a 9-year-old female with PAI-1 inhibitor deficiency using tranexamic acid (Cyclokapron).

Recurrent aortic occlusion.

In a review of 134 aortic occlusions in 123 patients, there were 10 patients that suffered recurrent aortic occlusions (RAO). These patients developed RAO after revascularization for primary aortic occlusion and presented with signs and symptoms of acute lower extremity ischemia. The recurrent occlusions occurred in one native aorta and in 10 aortobifemoral grafts.

Cefamandole versus cefazolin in vascular surgical wound infection prophylaxis: cost-effectiveness and risk factors.

Purpose: Recent studies of perioperative antimicrobial prophylaxis have indicated an improved efficacy of beta-lactamase-stable cephalosporins compared with cefazolin, the most commonly used prophylactic agent. Previous studies in our institution have revealed a superiority of cefamandole to cefazolin in patients undergoing heart surgery, although there was no difference between cefazolin and cefuroxime in patients undergoing peripheral vascular surgery. This study was therefore designed to compare cefamandole with cefazolin in wound infection prophylaxis in clean vascular surgery.

Suprarenal aortic occlusion.

Purpose: This report was designed to elucidate the clinical manifestations of suprarenal aortic occlusion (SRAO) and determine the efficacy of surgical treatment.

Methods: A retrospective review of 135 patients with aortic occlusion was undertaken from which the 16 patients (12%) with SRAO were found.

Results: Analysis yielded two subsets of patients based on the time-frame over which SRAO developed.

Surgical treatment of common carotid artery occlusion.

Eight patients with common carotid artery (CCA) occlusion underwent bypass with saphenous vein to either the carotid bifurcation (five), the internal carotid artery (two), or the external carotid artery (one). Indications included ipsilateral transient ischemic attack (two), recent nondisabling hemispheric stroke (two), and transient nonhemispheric cerebral symptoms (two). Two asymptomatic patients with CCA occlusion and contralateral internal carotid stenosis underwent prophylactic revascularization prior to planned aortic surgery.

The evolving surgical management of recurrent carotid stenosis.

The traditional approach to recurrent carotid stenosis has been repeat endarterectomy or patch angioplasty. Concern with the durability of repeat carotid endarterectomy has resulted in our use of carotid resection with autogenous graft interposition. This study was designed to determine the outcome and efficacy of carotid resection compared with repeat carotid endarterectomy in the management of recurrent carotid stenosis.

Juxtarenal aortic occlusion.

The authors' experience with 113 aortic occlusions in 103 patients during a 26-year period (1965 to 1991) is reviewed. The authors found three distinct patterns of presentation: group I (n = 26) presented with acute aortic occlusion, group II (n = 66) presented with chronic aortic occlusion, and group III (n = 21) presented with complete occlusion of an aortic graft. Perioperative mortality rates were 31%, 9%, and 4.

Surviving gastrointestinal infarction due to polyarteritis nodosa: a rare event.

Poly arteritis nodosa (PAN) is a systemic vasculitis with a male: female ratio of 2:1 and a peak incidence in the fifth decade. Small to medium-sized arteries are involved by focal transmural inflammatory necrosis. Aneurysms with inflammatory destruction of the media also occur.

Cefuroxime versus cefazolin as prophylaxis in vascular surgery.

Although cefazolin prophylaxis has proven efficacy in vascular surgery, Staphylococcus aureus wound infections are still an important postoperative complication. In cardiac surgery, cefazolin's susceptibility to hydrolysis by staphylococcal beta-lactamase has been proposed to account for some prophylaxis failures. To determine whether the incidence of vascular wound infections can be reduced by administering a more beta-lactamase-stable cephalosporin, we undertook a prospective, randomized trial of cefuroxime versus cefazolin.

Extended profundoplasty to minimize pelvic and distal tissue loss.

Multiple levels of aortoileofemoral occlusive disease may necessitate profundoplasty or extension of the outflow anastomosis to insure pelvic and distal arterial perfusion. During the period 1978 through 1988, 1637 patients underwent elective aortic reconstruction for aneurysmal or occlusive disease. One hundred forty-five had profundoplasty performed to ensure adequate outflow.

Recurrent carotid artery stenosis. Resection with autogenous vein replacement.

Recurrent carotid artery stenosis (RCAS) occurs in 10% to 15% of patients following carotid endarterectomy (CEA). A recurrent stenosis may occur as early as 6 months and will become symptomatic in 3% to 5% of patients. Early stenosis is myointimal hyperplasia, but with the passage of time may progress to the characteristic atherosclerotic lesion.

Analysis of a decade of carotid reconstructive operations.

Carotid artery reconstruction surgery for atherosclerotic lesions of the extracranial cerebral circulation has become the most common peripheral vascular operation. A better understanding of the indications for operative intervention, enhanced monitoring during surgery, and more precise management of intraoperative anesthesia have all decreased the risks associated with internal carotid endarterectomy (ICA). In an effort to evaluate the safety and efficacy of extracranial carotid reconstructive surgery, we reviewed 3028 operations performed in 2198 patients during the past decade (1977-1986).

Renal artery aneurysm: selective treatment for hypertension and prevention of rupture.

Thirty-nine patients with renal artery aneurysm (RAA) were seen over a period of 15 years. Among 20 women and 19 men, 31 were found to have solitary aneurysms, and eight had multiple RAA. Thirty-three patients had diastolic hypertension; nine of them proved to be of renovascular origin.

Ruptured abdominal aortic aneurysm: a 25-year experience and analysis of recent cases.

An 8-year experience with treatment of 58 patients with ruptured abdominal aortic aneurysm (RAAA) is reviewed with hospital mortality of 25.9 per cent. Added to a previously reported experience, 115 patients have been treated over 25 years with 33 per cent mortality.

Reflections from a decade of carotid reconstructive surgery.

Carotid artery reconstructive surgery for atherosclerotic lesions of the extracranial cerebral circulation has become the most common operation in peripheral vascular surgery. A better understanding of the indications for operative intervention, enhanced monitoring during surgery, and more precise management of intraoperative anesthesia have all helped decrease the risks associated with internal carotid endarterectomy. To evaluate the safety and efficacy of extracranial carotid reconstructive surgery, we reviewed 2,857 operations done on 2,087 patients from 1976 to 1985.

Prevention of stroke during carotid endarterectomy.

From 1976 through 1985, 2857 carotid reconstructive procedures were performed on 2087 patients. Postoperative neurologic deficit occurred in 59 patients (2.1%).
