Risk for surgical interventions following endovascular aneurysm repair with Endologix AFX or AFX2 Endovascular AAA Systems compared with other devices.

Objective: To evaluate the risk for 90-day returns to care and long-term subsequent surgical interventions after primary endovascular aneurysm repair (EVAR) with an Endologix AFX Endovascular AAA System compared with three other high-volume endograft devices.

Methods: We conducted a matched cohort study using data from Kaiser Permanente's Endovascular Stent Graft Registry. Patients aged ≥18 years who underwent primary EVAR for AAA in the health care system from January 1, 2011, to December 31, 2017, comprised the eligible study sample.

A framework for perioperative care for lower extremity vascular bypasses: A Consensus Statement by the Enhanced Recovery after Surgery (ERAS®) Society and Society for Vascular Surgery.

The Society for Vascular Surgery and the Enhanced Recovery After Surgery (ERAS) Society formally collaborated and elected an international, multi-disciplinary panel of experts to review the literature and provide evidence-based suggestions for coordinated perioperative care for patients undergoing infrainguinal bypass surgery for peripheral artery disease. Structured around the ERAS core elements, 26 suggestions were made and organized into preadmission, preoperative, intraoperative, and postoperative sections.

Perioperative care in open aortic vascular surgery: A consensus statement by the Enhanced Recovery After Surgery (ERAS) Society and Society for Vascular Surgery.

The Society for Vascular Surgery and the Enhanced Recovery After Surgery Society formally collaborated and elected an international, multidisciplinary panel of experts to review the literature and provide evidence-based recommendations related to all the health care received in the perioperative period for patients undergoing open abdominal aortic operations (both transabdominal and retroperitoneal approaches, including supraceliac, suprarenal, and infrarenal clamp sites) for aortic aneurysm and aortoiliac occlusive disease. Structured around the Enhanced Recovery After Surgery core elements, 36 recommendations were made and organized into preadmission, preoperative, intraoperative, and postoperative recommendations.

Outcomes of Wound Healing and Limb Loss After Transmetatarsal Amputation in the Presence of Peripheral Vascular Disease.

Transmetatarsal amputation (TMA) is the procedure of choice in treating forefoot gangrene and infection. Foot and ankle and vascular surgeons work closely together in limb salvage, but little is known about the timing of vascular intervention to achieve a healed amputation site. This study retrospectively looked at 153 patients with peripheral vascular disease who underwent TMA with a minimum of a 3-year follow-up.

Carotid endarterectomy in academic versus community hospitals: the national surgical quality improvement program data.

Background: Carotid endarterectomy (CEA) is among the most commonly performed vascular operations in both academic and community hospital settings. The excellent results of the large prospective studies (North American Symptomatic Carotid Endarterectomy Trial, Asymptomatic Carotid Atherosclerosis Study) have been criticized because of a widely held impression that community hospitals could not duplicate the excellent surgical results achieved in high volume university hospitals or clinics. The purpose of this study was to use the National Surgical Quality Improvement Program data to evaluate the outcomes of CEA in academic versus community hospitals.

Vascular complications of exposure for anterior lumbar interbody fusion.

Objective: The purpose of this study is to document the incidence of vascular complications during anterior lumbar interbody fusion (ALIF) in 212 consecutive patients treated at the Scripps Clinic and determine what factors adversely affected outcome.

Methods: We reviewed the prospectively maintained database of all ALIF procedures performed at Scripps Clinic between August 2004 and June 2009. All procedures were performed by a spine surgeon in conjunction with a vascular surgeon who performed the exposure portion of the operation, and protected the vessels from injury during the instrumentation phase of the operation.

Midterm results of a novel technique to salvage autogenous dialysis access in aneurysmal arteriovenous fistulas.

Purpose: Over the last decade, K-DOQI guidelines have increasingly emphasized the importance of autogenous arteriovenous fistulas (AVF) for dialysis access. A complication of AVF is aneurysmal dilatation with a subset developing massive diffuse aneurysm. Treatment of massive aneurysmal AVF generally involves either ligation or resection with use of prosthetic interposition.

Contemporary results of carotid endarterectomy for asymptomatic carotid stenosis.

Background And Purpose: The validity of carotid endarterectomy (CEA) for asymptomatic carotid stenosis has been questioned recently due to the increasing effectiveness of medical management. In this study, we evaluated how contemporary outcomes of CEA for asymptomatic carotid stenosis compare with published stroke rates for best medical management.

Methods: We identified all patients who underwent CEA for asymptomatic carotid stenosis from the 2005, 2006, and 2007 National Surgical Quality Improvement Program (NSQIP) database.

Pulmonary blood flow heterogeneity during hypoxia and high-altitude pulmonary edema.

Uneven hypoxic pulmonary vasoconstriction has been proposed to expose parts of the pulmonary capillary bed to high pressure and vascular injury in high-altitude pulmonary edema (HAPE). We hypothesized that subjects with a history of HAPE would demonstrate increased heterogeneity of pulmonary blood flow during hypoxia. A functional magnetic resonance imaging technique (arterial spin labeling) was used to quantify spatial pulmonary blood flow heterogeneity in three subject groups: (1) HAPE-susceptible (n = 5), individuals with a history of physician-documented HAPE; (2) HAPE-resistant (n = 6), individuals with repeated high-altitude exposure without illness; and (3) unselected (n = 6), individuals with a minimal history of altitude exposure.
