Blood flow in the pancreatic segment before and after transplantation.

Background: Blood flow in the pancreas before and after transplantation has not been studied sufficiently. Blood flow in the pancreatic transplant as a function of type vascular anastomosis used has not been explored.

Aim: The objective of our study was to study blood flow in the intact pancreas prior to harvesting and at different time periods after transplantation.

Endograft limb occlusion and stenosis after ANCURE endovascular abdominal aneurysm repair.

Objective: The purpose of this study was to define the incidence and treatment of endograft limb stenosis or occlusion (endograft limb dysfunction [ELD]) in a single center with the ANCURE unsupported bifurcated or aortouniiliac endograft by using intraoperative completion angiography and postoperative color duplex ultrasound scanning (CDU).

Methods: Sixty-seven endografts (58 bifurcated, 9 uniiliac) were implanted between February 1996 and July 2000. Intraoperative completion aortography was performed in every patient.

The incidence and natural history of type I and II endoleak: a 5-year follow-up assessment with color duplex ultrasound scan.

Purpose: The purpose of this study was the demonstration of the value of color duplex ultrasound (CDU) scanning in the detection of type I endoleak (T1EL) and type II endoleak (T2EL), the correlation of Doppler scan waveform pattern to endoleak persistence or seal, and the description of the natural history of endoleak.

Methods: The study was a retrospective review of 83 patients who underwent periodic CDU scan and computed tomographic (CT) scan surveillance of the endograft and aneurysm sac after insertion of an aortic endograft for abdominal aortic aneurysm (AAA). Forty-one patients (49%) with an endoleak at anytime in the follow-up period form the basis of this report.

Endotension after endovascular aneurysm repair: the Ancure experience.

Purpose: The expansion of aneurysms after endovascular repair is a consequence of persistent sac pressure, usually resulting from an endoleak. Several authors have suggested that sac expansion can occur even in the absence of endoleak, referring to this phenomenon as endotension. This study undertakes a review of the largest US endograft trial data to better define the significance of aneurysm expansion in the absence of endoleak.

Cyclic guanine monophosphate (cGMP) an intracellular mediator of cavernosal smooth muscle relaxation following penile vascular surgery.

Background: We describe a new surgical method for treatment of male impotence. This procedure allows preservation of erectile tissues and avoids the need for implantable devices. It was demonstrated, that after this procedure sustained and reproducible erections were feasible.
