Ruptured aneurysm of the splenic artery associated with fibromuscular dysplasia.

Rupture of a splenic artery aneurysm is a rare event associated with high mortality rates. Aneurysm of the splenic artery associated with fibromuscular dysplasia (FMD) is even rarer, with only 3 previously reported cases. We report a patient with previously undiagnosed FMD who required emergent intervention because of a ruptured splenic aneurysm.

Primary endoanchoring in the endovascular repair of abdominal aortic aneurysms with an unfavorable neck.

Purpose: To investigate the feasibility and early results of endoanchoring (endostapling) using a new commercially available device as an adjunctive procedure during endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAAs) with an unfavorable proximal neck.

Methods: Between June 2010 and May 2012, 13 consecutive patients (all men; median age 73 years, range 62-82) were prospectively enrolled in a 2-center registry to follow outcomes of adjunctive primary endoanchoring (Aptus HeliFX Aortic Securement System) of the proximal endograft to enhance proximal graft fixation and sealing during EVAR. Indications for proximal neck endoanchoring included at least one of the following: neck angulation 45° to 90°, length 8 to 15 mm, diameter 29 to 33 mm, conical neck configuration, or an irregularly shaped neck.

Endovascular retrieval of a dislodged femoral arterial closure device with Alligator forceps.

The Angio-Seal (St. Jude Medical, Minnetonka, Minn) is a frequently used percutaneous femoral artery closure device to obtain hemostasis after arterial catheterization. Separation and migration of the device, leading to distal embolization and limb-threatening ischemia necessitating emergency surgery, is reported but extremely rare.

Superior mesenteric artery stent fracture leading to recurrent mesenteric ischemia.

We report 2 cases of patients with recurrent symptoms of mesenteric ischemic disease after percutaneous transluminal angioplasty (PTA) and stenting due to superior mesenteric artery stent fracture. Both patients were treated by redo PTA and stenting successfully. Stent fractures, their complications, and management are discussed.

Fentanyl-fluanisone-midazolam combination results in more stable hemodynamics than does urethane alpha-chloralose and 2,2,2-tribromoethanol in mice.

Near-physiologic hemodynamic conditions for several hours were needed to study cardiovascular physiology in a murine model. We compared two commonly used anesthetic treatments, urethane alpha-chloralose (U-alphaCh; 968 mg U and 65 mg alphaCh/kg) and 2,2,2-tribromoethanol (TBE; 435 mg/kg) and fentanyl fluanisone midazolam (FFM; 3.313 mg fentanyl, 104.
