Effects of the type of embolization particles on carboplatin concentration in liver tumors after transcatheter arterial chemoembolization in a rabbit model of liver cancer.

Purpose: To study the effect of particle type used during transarterial hepatic chemoembolization (TACE) on carboplatin concentration after TACE in an animal model of liver cancer (VX2) and to determine the concentration of carboplatin within tumor, liver, and plasma.

Materials And Methods: The VX2 tumors were grown in the livers of 23 rabbits. Carboplatin (5 mg/kg) was selected because of its known potency against VX2 tumor.

Midterm survival after endovascular versus open repair of infrarenal aortic aneurysms.

Purpose: To report the midterm survival after endovascular repair (ER) of infrarenal aortic aneurysms and to compare the outcomes to contemporaneous patients treated with open repair (OR).

Methods: Between January 1995 and December 2001, 498 patients were treated for abdominal aortic aneurysm: 289 (52%) underwent OR and 209 (48%) underwent ER at a single center. Preoperative risk factors were graded according to the SVS/AAVS risk stratification.
