Open repair of pararenal aortic aneurysms: operative management, early results, and risk factor analysis.
Surgical treatment of pararenal aortic aneurysms, if compared to open surgical repair of infrarenal aneurysms, is technically more demanding and characterized by problems related to organ ischemia. To better define challenges, risks, and results, we analyzed our experience with the treatment of pararenal aortic aneurysms. Between January 1993 and March 2005, 119 consecutive patients underwent surgery for pararenal aneurysms at our institution. ⋯ One of the main risks of this surgery is renal morbidity. Preoperative renal insufficiency and long periods of renal ischemia are associated with a higher risk of postoperative deterioration of renal function that is often, but not always, reversible. Nowadays, pararenal aneurysm repair is a safe procedure, especially if performed electively.

This report describes two cases involving small-caliber gunshot wounds to the chest with embolization of the bullet (.22 long rifle). In the first patient, hemodynamic status permitted additional imaging before surgery. Findings demonstrated embolization of the bullet into the right external carotid artery after penetration into the left ventricle. ⋯ Bullet embolization into the left hypogastric artery through an acquired aortopulmonary fistula suspected during thoracic exploration was diagnosed after the procedure. Postoperative recovery was uneventful in both cases. The bullet in the hypogastric artery was not extracted, with no complications being observed after a follow-up period of 3 years.
