Purpose: To establish whether segmental transcatheter arterial chemoembolization (TACE) treatment may improve the rates of survival in patients with compensated cirrhosis and inoperable hepatocellular carcinoma (HCC).
Materials And Methods: Fifty-six patients with compensated cirrhosis and inoperable HCC were treated with segmental TACE. One hundred forty treatments (mean, 2.
Priapism is a prolonged penile erection not associated with sexual arousal. Two types of priapism have been described: the more common one is the "veno-occlusive" priapism and can be frequently observed as the consequence of an intracavernosal injection of vaso-active drugs for the treatment of erectile dysfunction. The less common type of priapism is known as "high flow" priapism and usually follows perineal or direct penile trauma.

Urological vascular complications (UVC) are largely secondary to percutaneous procedures that are nowadays extensevely used by the urologists and the nephrologists. The major frequency of UVC is observed after the renal biopsy, in a percentage varying from 7 to 17% in different series; UVC are less frequent after a nephrostomic procedure (near 1-3%). UVC consist of artero-venous fistulas (AVF) and pseudoaneurysms (PA), that generally cause haemorrhage, particularly macroscopic hematuria.

Herein we report the results obtained with 305 PTRAs performed in 242 hypertensive patients, 144 of whom had atherosclerotic RAS, 69 fibromuscolar dysplasia, 15 Ras in transplanted kidneys, 6 restenosis in surgically revascularized kidneys, 4 Takayasu arteritis and 4 neurofibromatosis. Stents were implanted in 68 cases, mostly in atherosclerotic stenoses.

Echo-Doppler studies were performed in 63 hypertensive patients with 68 renal artery stenoses (39 atherosclerotic and 29 fibromuscular) prior to and within five days after the dilation procedures (55 angioplasties, 13 stent implantations), which resulted in an average reduction of arterial narrowing from 79% to 20%. In 24 patients, the velocimetric indices were also examined in relationship to the venoarterial differences of plasma renin activity and of angiotensin II across the stenotic kidneys.
