The Role of Physician-Directed Duplex after Brachial Plexus Block in Arteriovenous Fistula Creation.

Background: Best practice guidelines for dialysis access creation emphasize distal sites and autogenous tissue before more proximal sites and synthetic shunts. Pre-operative vein mapping is a useful modality to evaluate optimal access location; however, vein size is often underestimated secondary to patient hypovolemia, room temperature, and basal vascular tone. Supraclavicular brachial plexus blocks (BPB) are routinely performed to provide surgical anesthesia but also have known vasodilatory effects.

Initial Post-Operative Visit Absenteeism is Associated With Worse Amputation-Free Survival after Tibial Angioplasty.

Objectives: Tibial revascularization is often performed in the setting of critical limb ischemia and tissue loss requiring close patient monitoring in the early post-operative period for worsening gangrene and/or ischemia. Multiple studies have shown loss to follow-up is an independent risk factor for poor outcomes in several vascular procedures. Therefore, we evaluated the risk factors relating to loss to follow up against outcomes in patients undergoing tibial endovascular procedures with the hypothesis that poor post-operative visit compliance is associated with decreased amputation-free survival rates.

Late Open Repair of a Massive Common Iliac Artery Aneurysm after Endovascular Failure.

Giant Common Iliac Artery Aneurysms (CIAA) are an uncommon pathology that may present as a late complication after endovascular aortic repair secondary to aneurysmal degeneration with endoleak. We present an unusual case of a patient presenting 9 years after index endovascular CIAA exclusion with a painless abdominal mass found to be a 20+ cm CIAA secondary to type II endoleak from a recanalized coil embolized hypogastric artery. The patient underwent open aneurysmorrhaphy with ligation of the hypogastric artery.

Clinically occult amyloidosis derived from leukocyte chemotactic factor 2 (ALECT 2) with cardiac involvement complicating renal transplantation: case report and literature review.

Introduction: Amyloidosis derived from leukocyte chemotactic factor 2 (ALECT2) may be associated with slowly progressive renal failure that is clinically unsuspected at the time of transplantation. While this is typically clinically insignificant, we report a case with extensive systemic ALECT2 amyloidosis that also involved the myocardium, contributing to perioperative death post renal transplantation.

Case Description: A 72-year-old Hispanic woman presented for renal transplantation due to end-stage renal disease secondary to hypertension.

Complex endovascular repair of type B aortic dissection and predicting left arm ischemia: a case report.

Background: Thoracic endovascular aortic repair (TEVAR) is the gold standard for surgical management of descending thoracic aortic pathology. Depending on the anatomy, TEVAR often requires deployment across the origin of the left subclavian artery (LSA) to obtain a proximal seal, thus potentially compromising perfusion to the left upper extremity (LUE). However, in most patients this is generally well tolerated without revascularization due to collateralization from the left vertebral artery (LVA).

Frailty is a Poor Predictor of Postoperative Morbidity and Mortality After Ruptured Abdominal Aortic Aneurysm.

Background: Frailty has gained prominence as a predictor of postoperative outcomes across a number of surgical specialties, vascular surgery included. The role of frailty is less defined in the acute surgical setting. We assessed the prognostic value of frailty for patients undergoing surgery for a ruptured abdominal aortic aneurysm (rAAA).

Extravascular reconstruction of a congenitally absent inferior vena cava.

Congenital absence of the inferior vena cava is an uncommon venous anomaly with treatment algorithms consisting of predominately medical management. We present a case of a 36-year-old man with venous ulcers who had failed conservative treatment for recurrent venous ulcers. From a catheter directed approach, we were able to develop an extravascular retroperitoneal space and perform an iliocaval reconstruction with Wallstents.

Concomitant Aorto-Caval Reconstruction for Inferior Vena Cava Leiomyosarcoma.

Background: Leiomyosarcoma of the inferior vena cava (IVC) is a rare smooth muscle neoplasm typically presenting in the fifth to sixth decades of life with both intraluminal and extraluminal growth patterns. Surgical resection remains the gold standard for nonmetastatic disease and often requires vascular reconstruction. We present an atypical case of leiomyosarcoma involving both the IVC and infrarenal abdominal aorta necessitating reconstruction with intraoperative veno-venous bypass.

Anesthesia Type is Associated with Decreased Cranial Nerve Injury in Carotid Endarterectomy.

Background: Anesthesia modalities for carotid endarterectomy continue to vary nationally. We evaluated and compared short-term outcomes after carotid endarterectomy with general anesthesia (GA) and regional anesthesia (RA) in both symptomatic and asymptomatic patients.

Methods: The 2011-2015 American College of Surgeons National Surgical Quality Improvement Program Participant Use Data Files (PUFs) with merged Vascular Procedure-Targeted PUFs for carotid endarterectomy were queried for patients undergoing carotid endarterectomy.

Intraoperative transradial angiography augments safe hysterectomy for uterine fibroids in the setting of ambiguous arterial anatomy: a case report.

Background: Transfemoral access is the traditional gold standard for uterine artery angiography; however, transradial access is gaining in popularity because of its decreased complication profile and patient preference. We present a case of a patient who underwent successful total abdominal hysterectomy for symptomatic uterine fibroids with ambiguous pelvic vasculature that would have been otherwise aborted if it were not for intraoperative transradial access angiography.

Case Presentation: A 52-year-old Caucasian woman presented to her gynecologist for an elective total abdominal hysterectomy and bilateral salpingo-oophorectomy.

Use of liposomal bupivacaine in the postoperative management of posterior spinal decompression.

OBJECTIVE The aim in this paper was to evaluate the efficacy of long-acting liposomal bupivacaine in comparison with bupivacaine hydrochloride for lowering postoperative analgesic usage in the management of posterior cervical and lumbar decompression and fusion. METHODS A retrospective cohort-matched chart review of 531 consecutive cases over 17 months (October 2013 to February 2015) for posterior cervical and lumbar spinal surgery procedures performed by a single surgeon (J.J.

Scavenger receptor class A member 5 (SCARA5) and suprabasin (SBSN) are hub genes of coexpression network modules associated with peripheral vein graft patency.

Objective: Approximately 30% of autogenous vein grafts develop luminal narrowing and fail because of intimal hyperplasia or negative remodeling. We previously found that vein graft cells from patients who later develop stenosis proliferate more in vitro in response to growth factors than cells from patients who maintain patent grafts. To discover novel determinants of vein graft outcome, we have analyzed gene expression profiles of these cells using a systems biology approach to cluster the genes into modules by their coexpression patterns and to correlate the results with growth data from our prior study and with new studies of migration and matrix remodeling.
