A 73-year-old female was referred to our hospital with a diagnosis of advanced transverse colon cancer with severe anemia and body weight loss. Preoperative evaluations, including colonoscopy, gastroduodenoscopy, and computed tomography, revealed not only a transverse colon cancer massively...

The efficiency of the new Yasargil titanium fenestrated mini-clips for ideal clipping of a cerebral aneurysm.

Surgical neurology international
