Example of evoked potential monitoring for a neurogenic tumor positioned high in the mediastinum.

Excision of a neurogenic tumor of the brachial plexus positioned high in the mediastinal space could potentially result in a functional disorder of the arm. We report on a case in which we performed evoked potential monitoring on a tumor located high in the mediastinum. We found large potential changes in the median and ulnar nerve areas and had a concern that the excision might injure the brachial plexus.

Repair of ventricular septal perforation with asymmetrical conical patch exclusion.

We report a case of repair of the postinfarction ventricular septal perforation (VSP), using an equine pericardium tailored in an asymmetrical conical shape for exclusion (modified sack technique) and an additional direct patch closure of VSP. An asymmetrical conical patch is easily sutured to the normal septum away from the VSP edge by using the longer part of the cone border. The postoperative left ventriculogram 1.

Isolated iliac artery aneurysmocolonic fistula with pericolic abscess.

We report the successful management of a 66-year-old man who had common iliac aneurysmosigmoid colon fistula. The initial presentation was abdominal pain, fever, and melena. Digital subtraction angiography showed no evidence of rupture.
