We assessed the distribution of secondary interventions after aortic stent grafting (EVAR) performed to treat infrarenal abdominal aortic aneurysm (AAA), and evaluated clinical success and survival in patients who underwent a secondary procedure (group 2) compared with patients who did not undergo a secondary procedure (group 1). ⋯ With close follow-up and a significant number of secondary operations, this 8-year experience has not included any aneurysm ruptures to date. Secondary operations did not lead to increased mortality, but were associated with more surgical conversions and with a higher clinical failure rate.

This study was undertaken to determine the effect of the preoperative diameter of abdominal aortic aneurysms on the midterm outcome after endovascular abdominal aneurysm repair (EVAR). ⋯ The midterm outcome of large aneurysms after EVAR was associated with increased rates of aneurysm-related death, unrelated death, and rupture. Reports of EVAR should stratify their outcomes according to the diameter of the aneurysm. Large aneurysms need a more rigorous post-EVAR surveillance schedule than do smaller aneurysms. In small aneurysms EVAR was associated with excellent outcome. This finding may justify reappraisal of currently accepted management strategies.

Ipsilateral vertebral artery injuries are a rare entity following trauma to the neck. We discuss the first case of an isolated right vertebral artery injury in a patient with a left stab wound. ⋯ We emphasize the importance for trauma surgeons to be familiar with basic but important vascular exposures. The anatomy, surgical exposure, and management of these rare injuries are discussed.

Established American Heart Association guidelines recommend the use of statin drugs, angiotensin converting enzyme (ACE) inhibitors, and antiplatelet agents in patients with systemic atherosclerosis, such as those undergoing operative intervention to treat peripheral atherosclerotic disease. Many of these patients have not received treatment of coronary heart disease and have not been prescribed these medications. Whether statin drugs and ACE inhibitors confer an improvement in graft patency, limb salvage, and operative mortality is unknown. ⋯ Patients undergoing infrainguinal bypass are undertreated with respect to cardioprotective medications. ACE inhibitor use is associated with lower mortality, and statin drug use is associated with improved graft patency and limb salvage. Institution of consensus guidelines concerning these medications should be considered by all vascular specialists, including vascular surgeons.

Deep thigh veins, including the superficial femoral, superficial femoropopliteal, and profunda femoris veins, are versatile autogenous conduits for arterial reconstruction. Although late venous complications are unusual, deep vein harvest may induce severe venous hypertension and predispose the limb to acute compartment syndrome. The purpose of this study was to define the frequency of fasciotomy in patients undergoing deep vein harvest and to identify clinical predictors of the need for fasciotomy after deep vein harvest. ⋯ One in four patients undergoing deep vein harvest for aortofemoral reconstruction may be expected to develop acute compartment syndrome and require fasciotomy. The risk appears to be greatest in patients with severe lower extremity ischemia and in patients undergoing simultaneous GSV and deep vein harvest. Prophylactic fasciotomy may be appropriate in patients with both risk factors, but vigilance for the development of compartment syndrome after deep vein harvest is required in all patients undergoing deep vein harvest for aortofemoral reconstruction.
