Median arcuate ligament syndrome is rare, and as a diagnosis of exclusion, diagnosis and treatment paradigms can be unclear. Based on previously published studies, symptom relief can be achieved with a variety of interventions including celiac ganglionectomy as well as open, laparoscopic, or robotic intervention.

The following research examines the creation of a new small-diameter bypass graft. It is clinically relevant to patients who need distal arterial bypass, coronary artery bypass, or hemodialysis access, but who do not have adequate autologous vein for their surgeries. Future investigations will involve further tissue engineering of this vascular scaffold (eg, autologous endothelial seeding of its lumen) and testing the clinical usefulness of the completed graft.

Background-Adipose tissue is a readily available source of multipotent adult stem cells for use in tissue engineering/regenerative medicine. Various growth factors have been used to stimulate acquisition of endothelial characteristics by adipose-derived stem cells (ASC). Herein we study the effects of endothelial cell growth supplement (ECGS) and physiologic shear force on the differentiation of ASC into endothelial cells.

This study suggests that negative pressure therapy significantly reduces the major wound complication, reoperation, and readmission rates for patients at high risk for groin wound complications. Furthermore, this therapy may lead to a reduction in hospital costs. Negative pressure therapy for all groin incisions considered at high risk for wound complications is recommended.

May-Thurner syndrome is a rare clinical entity involving venous obstruction of the left lower extremity. Obstruction occurs secondary to compression of the left common iliac vein between the right common iliac artery and the underlying vertebral body. Current management largely involves endovascular therapy. A review was conducted of six studies containing at least five patients with May-Thurner syndrome treated by endovascular therapy. We compiled data on 113 patients, analyzing patient demographics, treatment details, and outcome. An 18-year-old female presented 1 week after the onset of left lower extremity pain and swelling. Duplex ultrasonography revealed extensive left-sided deep venous thrombosis (DVT). Thrombolysis followed by iliac vein stent placement restored patency to the venous system, with subsequent resolution of symptoms. Review of 113 patients revealed that the majority were females (72%) presenting with DVT (77%), most of which was acute in onset (73%). Therapy consisted of catheter-directed thrombolysis and subsequent stent placement in the majority of patients, resulting in a mean technical success of 95% and a mean 1-year patency of 96%. Endovascular therapy is the current mainstay of treatment for May-Thurner syndrome. Review of the current literature supports treatment via catheter-directed thrombolysis followed by stent placement with good early results.
