Coronary subclavian steal syndrome unamenable to angioplasty successfully managed with subclavian-subclavian bypass.

Purpose. Coronary-subclavian steal syndrome (CSSS) is defined as a reversal of flow in a previously constructed internal mammary artery (IMA) coronary conduit, producing myocardial ischemia. We present a case of CSSS which could not be ameliorated with endovascular therapy and necessitated a subclavian-subclavian bypass.

The role of anatomic factors in predicting success of endovascular repair of thoracic aortic aneurysms.

Objective: We evaluated the results of thoracic endovascular aneurysm repair (TEVAR) to determine what anatomic factors influenced the clinical outcomes.

Methods: Preoperative computed tomography (CT) angiograms of 65 patients who underwent TEVAR were analyzed using 3-dimensional imaging. The proximal and distal neck, thoracic aneurysm, and iliac arteries were measured for angulation, diameter, length, calcification, and tortuosity.

Single port access (SPA) cholecystectomy: a completely transumbilical approach.

We have seen substantial changes in minimally invasive surgery since its development in the early 1900s. Over the past 10 years, the addition of natural orifice transluminal endoscopic surgery and robotics has turned our attention to improved cosmesis and advancements in instrumentation. We have developed a new technique-single port access (SPA) surgery-and have applied it to the cholecystectomy.

Venous ulcers: new options in treatment: minimally invasive vein surgery.

Venous disease has a spectrum of presentations. The most advanced state of chronic venous insufficiency (CVI) managed by wound care specialists being ulceration of the lower extremity. The goal of all treatments for advanced venous disease is to decrease ambulatory venous hypertension.

Incidence and outcome of filter occlusion during carotid artery stent procedure.

Recent reviews of device-specific complications using neuroprotection have addressed technical difficulties during delivery as well as adverse outcomes, intraoperative and 30-day. Little has been written, however, regarding the relevance of filter occlusion during the carotid stent procedure. A retrospective review was conducted of patients undergoing carotid artery stent procedures using a variety of neuroprotection devices from 2003 to 2007.

In vivo pulmonary tissue engineering: contribution of donor-derived endothelial cells to construct vascularization.

Intrapulmonary engraftment of engineered lung tissues could provide a potential therapeutic approach for the treatment of pediatric and adult pulmonary diseases. In working toward this goal, we report here on in vivo generation of vascularized pulmonary tissue constructs utilizing the subcutaneous Matrigel plug model. Mixed populations of murine fetal pulmonary cells (FPCs) containing epithelial, mesenchymal, and endothelial cells (ECs) were isolated from the lungs of embryonic day 17.
