Left Common Iliac Artery Aneurysm Rupture to an Iliac Vein with a Venous Anomaly: A Case Report.

Ruptured iliac artery aneurysms are serious conditions with high mortality, occasionally perforating into the venous system. A 73-year-old male presented with left leg edema and a pulsatile left lower abdominal mass. Computed tomography revealed a ruptured left common iliac artery aneurysm with perforation into the left common iliac vein.

Contractile elements and their sympathetic regulations in the pig urinary bladder: a species and regional comparative study.

Contractile behaviour of the urinary bladder and its sympathetic inhibition during storage phases are not well understood. Here, we explore muscularis mucosae (MM) as a predominant mucosal contractile element and the capability of sympathetic nerves to relax detrusor smooth muscle (DSM) or MM. Distribution of α-smooth muscle actin (α-SMA)-immunoreactive cells was compared in pig, human, guinea pig, rat and mouse bladders by immunohistochemistry, while contractility of the bladder mucosa was compared in these species by isometric tension recordings.
