Mesenteric blood flow and muscle sympathetic nerve activity during vasovagal syncope.

Purpose: Vasovagal syncope is thought to be mediated by a progressive fall in cardiac output secondary to venous pooling of blood in the splanchnic circulation. How and when this occurs before syncope has not been determined.

Methods: A total of 20 patients who became hypotensive during head-up tilt (age 40.

Segmental arterial mediolysis after fenestrated endovascular abdominal aortic aneurysm repair-A rare complication.

Segmental arterial mediolysis (SAM) is a rare, noninflammatory, nonatherosclerotic condition that occurs commonly in mesenteric vessels. There are no known predisposing risk factors to the development of SAM. We present a case of a 67-year-old woman who presented with abdominal pain 2 days following discharge after an elective endovascular abdominal aortic intervention.

Carnosine as a potential therapeutic for the management of peripheral vascular disease.

Aims: To evaluate the potential role of carnosine in the management of peripheral vascular disease.

Data Synthesis: Peripheral vascular disease is growing in its burden and impact; however it is currently under researched, and there are a lack of strong, non-invasive therapeutic options for the clinicians. Carnosine is a dipeptide stored particularly in muscle and brain tissue, which exhibits a wide range of physiological activities, which may be beneficial as an adjunct treatment for peripheral vascular disease.

Pseudoendoleak: A post-endovascular aortic repair ultrasound surveillance pitfall - Single institution case series.

Introduction: In the context of increasingly common endovascular treatment for abdominal aortic aneurysms, endoleak is a relatively common complication of (abdominal) EVAR, and ongoing multimodality surveillance programs are recommended by expert bodies including the Society for Vascular Surgery (SVS). We describe the colour doppler ultrasound (CDUS) finding defined as pseudoendoleak that may be misinterpreted as significant endoleak and may be resolved through the use of contrast-enhanced ultrasound (CEUS).

Methods: Retrospective review of cases at our institution identified five cases where apparent endoleak on CDUS was not evident on CEUS, performed immediately following CDUS.
