Association of anaesthesia technique with 30-day primary graft patency after open lower limb revascularization: retrospective cohort study.

Background: The relationship between anaesthetic technique and graft patency after open lower limb revascularization is unclear. The aim of this study was to evaluate the association between 30-day graft patency after elective infrainguinal bypass and anaesthetic technique (regional anaesthesia (RA, i.e.

Vascular Access Complications and Clinical Outcomes of Vascular Surgical Repairs Following Transcatheter Aortic Valve Implantation (TAVI).

Background: Transcatheter aortic valve implantation (TAVI) procedures have revolutionized the treatment of aortic stenosis. However, due to large sheaths, improperly deployed closure devices, and the comorbidities and challenges innate to this population, vascular access complications can be devastating. The objective of this study is to evaluate vascular access complications in one of the largest TAVI sites in North America.

Tailoring intermolecular interactions to develop a low-temperature electrolyte system consisting of 1-butyl-3-methylimidazolium iodide and organic solvents.

Ionic liquids (ILs) exhibit remarkable properties and great tunability, which make them an attractive class of electrolyte materials for a variety of electrochemical applications. However, despite the promising progress for operating conditions at high temperatures, the development of their low-temperature viability as electrolytes is still limited due to the constrains from thermal and ion transport issues with a drastic decrease in temperature. In this study, we present a liquid electrolyte system based on a mixture of 1-butyl-3-methylimidazolium iodide ([BMIM][I]), γ-butyrolactone (GBL), propylene carbonate (PC), and lithium iodide (LiI) and utilize its molecular interactions to tailor its properties for extremely low-temperature sensing applications.

A comparison of revision using distal inflow and distal revascularization-interval ligation for the management of severe access-related hand ischemia.

Objective: Access-related hand ischemia (ARHI) is a potentially limb-threatening complication of arteriovenous access for dialysis. The distal revascularization-interval ligation (DRIL) and revision using distal inflow (RUDI) procedures both allow treatment of ischemic symptoms while maintaining fistula patency. Although outcomes with the DRIL are well established, experience with the RUDI for ARHI remains preliminary.

Antegrade balloon occlusion of inferior vena cava during thrombectomy for renal cell carcinoma.

Nephrectomy with inferior vena cava (IVC) thrombectomy for advanced renal cell carcinoma (RCC) is a challenging and morbid surgical case. We describe the use of a simple endoluminal technique to occlude the suprahepatic IVC during thrombectomy. A 60-year-old male presented with a large right-sided RCC and IVC tumour thrombus.

Endovascular aortic aneurysm repair via the left ventricular apex of a beating heart.

An elderly man presented with a ruptured aortic arch, left lung compression, and hemoptysis. Multiple comorbidities and inadequate aortoiliac access disqualified him from conventional open repair or hybrid retrograde transarterial thoracic endovascular aortic repair (TEVAR). Because our center has recently reported that a thoracic aortic endograft can be successfully placed through the apex of the LV of a beating heart in a pig model, we received approval for the compassionate use of antegrade transapical TEVAR (TaTEVAR) with bilateral femoral-carotid revascularization to repair the aortic arch.

Successful ventricular transapical thoracic endovascular graft deployment in a pig model.

Purpose: Aortoiliac occlusive disease may preclude retrograde thoracic endovascular aortic repair. This study evaluated the physiologic and anatomic feasibility of introducing an aortic endograft in an antegrade manner into the descending thoracic aorta of a pig through the left ventricular apex.

Methods: Twelve adult pigs were to undergo antegrade endograft deployment.

Percutaneous closure of a para-anastomotic abdominal aortic graft leak.

Para-anastomotic graft leaks are a potential complication following surgical repair of an aortic aneurysm. Reoperation may be associated with significant morbidity and mortality. We report successful percutaneous transcatheter closure of an anastomotic graft leak utilizing an occluder device.

Removing the infected aortofemoral graft using a two-stage procedure with a delay between the stages.

This study describes the results of a procedure for removing the infected aortofemoral graft using a two-stage procedure with a delay between the stages. The objective was to lessen the morbidity and mortality associated with removing an infected graft through a single operation. Eight consecutive patients were treated in this manner over a 6-year span.

Results of prosthetic-vein composite graft with remote popliteal arteriovenous fistula in infragenicular bypass.

Objective: The purpose of this study is to report the results of a novel procedure for femoral-distal bypass grafting using a composite graft with an adjunctive remote popliteal fistula distal to the prosthetic portion of the graft. This reconstruction was developed for use in limb salvage in the absence of satisfactory autogenous vein.

Method: Data were collected prospectively on all patients undergoing this procedure from January 1, 1993 to December 31, 1999.
