The angiographic incidence of the HFA is more common than previously reported. The delayed and persistent opacification of the HFA on hepatic angiograms caused by its slow blood flow is considered the key to its identification.

Percutaneous transcatheter embolization of the testicular vein was performed on 28 patients with angiographically proven varicocele testis. In 2 patients bilateral and in 26 only the left vein was embolized using 3-, 5-, or 8-mm stainless steel coils. All patients had clinically palpable varicoceles and male infertility. The grade of varicoceles improved after embolization in 23 of 28 cases (82%). Effective sperm count increased significantly from 34.5 ± 44.6 to 65.1 ± 71.0 following embolization. However, pregnancy was achieved only in one of 28 cases. Technically, the basilic vein approach was felt to be superior to the femoral vein or jugular vein approach for this procedure.

The postcontrast CT scans and angiography of 26 lesions in 23 patients with hepatomas who underwent transcatheter arterial embolization therapy were reviewed. Newly developed low density and high density areas and gas were noted on CT scans of the tumors after embolization in 100, 8 and 58% of the lesions, respectively. The CT findings of residual tumors correlated well with those of follow-up angiography. When discrete smooth round low density zones were observed on CT, there was no residual neovascularity on follow-up arteriography. When there were nodular or thick septum-like structures in low density lesions, arteriography revealed residual tumor vascularity in the lesions. CT proved useful not only in evaluating the effects of embolization, but also in providing important information about residual tumors.

A series of 185 patients, 133 males and 52 females, were treated by ileal conduit urinary diversion in the past 17 years. The patients ranged in age from 7 months to 81 years with an average of 59 years. Diversions were performed for malignant diseases in 174 patients, 85% of whom underwent a simultaneous radical surgery. The follow-up covered the postoperative period from 4 months to 16 years 8 months with an average of 4 years 8 months. Six patients (3%) died within 1 month of operation, and 43 of a total of 58 mortal cases died of cancer thereafter. The survival rates of 143 patients with bladder cancer were 84% for 1 year, 72% for 3 years, 67% for 5 years, 62% for 10 years and 54% for 15 years. Early complications were noticed in 38% of the patients. Delayed wound healing due to local infection (20%) and intestinal obstruction (10%) were the two major complications in this period. Late complications were encountered in 51% of the patients. Mild peristomal dermatitis (22%) and gradually developing renal complications (22%) are two major problems in the standard ileal conduit urinary diversion. The latter was significantly more frequent in patients who underwent the operation between 1973 and 1981 than in those who had the surgery between 1982 and 1989. Postoperative hydronephrosis was observed in 15 (13%) of 117 patients who showed normal urograms preoperatively. Ileoureteral reflux was observed in 50% of the cases with nonobstructing conduits, while it increased up to 70% along with obstruction of the conduit.(ABSTRACT TRUNCATED AT 250 WORDS)
