Treprostinil sodium (Remodulin), a prostacyclin analog, in the treatment of critical limb ischemia: open-label study.

The purpose of this study was to assess the safety of continuous subcutaneous therapy with treprostinil sodium (Remodulin), a prostacyclin analog, and its effect on ischemic rest pain and ischemic wound healing in subjects with critical limb ischemia (CLI) and no planned revascularization procedure. This was a 12-week, open-label, single-center pilot study enrolling 10 subjects (mean age 82.4 years) with Fontaine stage III to IV (Rutherford class 4-6) peripheral arterial disease and ankle brachial indices less than 0.

Surgical management of peripancreatic arterial aneurysms.

Peripancreatic artery aneurysms--gastroduodenal (GDA) and pancreaticoduodenal (PDA)--are highly unusual. We report 4 such aneurysms and have collated reports of true peripancreatic artery aneurysms based on an extensive review of the English literature. From this review, patient characteristics, clinical behavior, outcome and management strategies are assessed.

Surveillance venous duplex is not clinically useful after total joint arthroplasty when effective deep venous thrombosis prophylaxis is used.

The early detection of deep venous thrombosis (DVT) and treatment with systemic anticoagulation to prevent pulmonary embolism (PE) are essential in the management of patients undergoing total joint arthroplasty (TJA). However, improvements in prophylactic measures have significantly decreased the occurrence of DVT in these patients. The purpose of this study was to determine whether routine postoperative duplex surveillance for DVT remains clinically useful.

Endovascular exclusion of a postendarterectomy carotid pseudoaneurysm.

Carotid pseudoaneurysms are rare occurrences. They often result from trauma, but can also present following carotid endarterectomy. Treating such pseudoaneurysms can be difficult due to previous surgery and limited access to the high internal carotid artery.

Endovascular repair of external iliac artery occlusion after hip prosthesis migration.

Purpose: To report emergent endovascular intervention to restore lower extremity arterial patency after migration of a hip prosthesis caused thrombosis of the external iliac artery (EIA).

Case Report: Nine months following left hip revision arthroplasty, a 66-year-old woman presented to the Emergency Department with the complaints of an acutely painful left lower extremity for over 6 hours. Imaging showed the metallic acetabular portion of the hip prosthesis in the iliac fossa, with severe external compression of the EIA.

Pseudoaneurysm of the lateral plantar artery after foot laceration.

Two children with lateral plantar artery pseudoaneurysms are presented. Both cases were associated with a plantar laceration and were successfully treated with ligation. Only one other report of a lateral plantar artery pseudoaneurysm was found in the literature; no reports involving the medial plantar artery have been reported.

Are multiple objective measures of student performance necessary?

Background: This study examines the effect of using multiple modalities to evaluate medical students.

Methods: Thirty-four students were evaluated by a complex model utilizing National Board of Medical Examiners (NBME) shelf examination, Objective Structured Clinical Examination (OSCE), Computer Patient Simulation (CPS), faculty and peer evaluation. Results were compared with a traditional model based on NBME and faculty evaluation alone.
