Endovascular abdominal aortic aneurysm repair in a patient with Ehlers-Danlos syndrome.

Ehlers-Danlos syndrome is a connective tissue disorder caused by abnormal collagen synthesis. Vascular complications, including aneurysm formation and spontaneous arterial perforations, are difficult to manage surgically and result in significant operative mortality due to blood vessel fragility. We describe the first reported successful endovascular abdominal aortic aneurysm repair in a patient with Ehlers-Danlos syndrome.

Lower extremity revascularization based on intraoperative arteriography.

The traditional approach to patients with lower extremity ischemia involves "diagnostic" arteriography performed in a radiology angiography suite prior to a separate revascularization in an operating room suite. This time-honored and staged approach has the disadvantage of an associated significant angiographic complication rate. Furthermore, in view of the accuracy of noninvasive testing and the capacity for intraoperative arteriography, this separation of diagnostic and reparative techniques may be outdated and cost-ineffective.

Vascular injuries during gynecological laparoscopy--the vascular surgeon's advice.

Context: Iatrogenic vascular problems due to laparoscopy are a well recognized problem and lead to significant repercussions. In this context, a ten-year review of cases topic is presented, based on experience gained while heading two important vascular surgery services.

Cases: Five patients with vascular injuries during elective laparoscopy are described.

Prenatal methylazoxymethanol exposure alters evoked responses in fetal rats.

Although there is considerable interest in identifying methods to detect central nervous system impairment early in development, few behavioral assessment tools are available for detecting CNS deficits in the fetus. In the present study, methylazoxymethanol [MAM; Midwest Research Institute, (MRI)] was used to induce deficits in CNS development in fetal rats to assess effects on coordinated fetal behavior. Fetuses were exposed by administering MAM to pregnant rats on E17 of gestation via intraperitoneal injection and then were prepared for behavioral testing 3 days later on E20.

Surgical thrombectomy and transluminal balloon angioplasty for failed above-knee femoropopliteal polytetrafluoroethylene bypass grafts.

Endovascular therapy offers an alternative to redo bypass or surgical graft revision for failed above-knee femoropopliteal PTFE bypass grafts. We evaluated the outcome of surgical thrombectomy and balloon angioplasty for the treatment of thrombosed bypass grafts. Thirty selected patients with thrombosed above-knee femoropopliteal PTFE bypass grafts were treated.
