Management of secondary hemorrhage from early graft failure in military extremity wounds.

Background: Secondary hemorrhage after a dehisced vascular reconstruction is a dreaded complication, yet few reports describe the initial management and outcome of casualties with ruptured grafts from military wounds. We aimed to report a single-center experience of graft ruptures after evacuation of casualties to a tertiary hospital in the continental United States.

Methods: Trauma records of US combat casualties were retrospectively reviewed from April 2005 to August 2007.

Advances in resuscitation in the setting of vascular injury.

Damage control surgery with the principles of expeditious control of hemorrhage and contamination, followed by predominant crystalloid resuscitation in the intensive care unit has saved the lives of many severely injured trauma patients. Unfortunately, crystalloid resuscitation has too often led to worsening of coagulopathy in the setting of vascular injury. The recent conflicts in Iraq and Afghanistan have created injured patients with severe vascular injury and massive soft tissue destruction creating early and profound coagulopathy associated with high rates of mortality.

The role of anatomic factors in predicting success of endovascular repair of thoracic aortic aneurysms.

Objective: We evaluated the results of thoracic endovascular aneurysm repair (TEVAR) to determine what anatomic factors influenced the clinical outcomes.

Methods: Preoperative computed tomography (CT) angiograms of 65 patients who underwent TEVAR were analyzed using 3-dimensional imaging. The proximal and distal neck, thoracic aneurysm, and iliac arteries were measured for angulation, diameter, length, calcification, and tortuosity.

Hybrid repair of bilateral subclavian artery aneurysms in a patient with Marfan syndrome.

A 32-year-old man with Marfan syndrome presented with enlarging, asymptomatic bilateral subclavian artery aneurysms. He has an extensive surgical history including aortic arch and descending thoracic aorta replacement. The L aneurysm was treated first with an L carotid-vertebral artery vein bypass, aneurysm debranching, and stent-graft repair of aneurysm via the L brachial artery approach.

Carotid artery pseudo-occlusion: does end-diastolic velocity suggest need for treatment?

Objective: We reviewed our institution's experience with carotid artery pseudo-occlusion (CAPO), to investigate whether internal carotid artery (ICA) end-diastolic velocity (EDV) as measured by duplex ultrasonography, was a predictor of need for further intervention.

Methods: From February 2003 to January 2008, 7478 patients underwent duplex ultrasonographic evaluation of their carotid arteries. Diagnosis of CAPO included the appearance of a narrow flow jet (string sign) on power doppler images, low velocities in the ICA and additional criteria listed below.

Successful repair of popliteal artery pseudoaneurysm after tibial lengthening osteotomy in a 7-year-old boy.

Popliteal artery injury is a known but rare complication of elective orthopedic procedures. This case report describes the diagnosis and treatment of a popliteal artery pseudoaneurysm and arteriovenous fistula after a tibial lengthening osteotomy in a 7-year-old boy.
