Arterial complications of hydatic disease are rarely encountered. We report a false hydatic aneurysm of the thoracoabdominal aorta revealed by ischemic embolism of the lower limbs. Surgical treatment included aorto-aortic prosthesis and albendazol for 6 months. Results at 18 months are excellent with negative hydatic serology. In endemic areas, hydatic disease is a possible cause of false aneurysms. Long-term surveillance is required after curative surgery and medical treatment.

Four new arterial lesions observed with Behçet's disease are reported: two popliteal aneurysms, one carotid aneurysm and one carotid stenosis. The clinical features, therapeutic modalities and postoperative complications of these uncommon lesions are reviewed briefly.

In Morocco, thromboangiitis obliterans (TAO) is the most common cause of obliterating arteriopathy in subjects under 40 years: 252 cases out of 291, versus 21 cases of diabetic arteritis and 18 miscellaneous causes. The anatomo-clinical appearance is in keeping with the criteria for Buerger's disease with the exception of superficial migratory thrombophlebitis. The absolute basis of treatment has been the total definitive discontinuation of smoking. Platelet anti-aggregant agents have also been used. Aside from limited resections of distal gangrenous regions (168 cases), surgery has been limited to lumbar sympathectomy without adrenalectomy (154 cases). Out of 133 patients regularly followed up for more than one year, results were good in 102 patients. The 39 poor results occurred exclusively in patients who continued or restarted smoking.

A personal series of 600 cases of vesicovaginal fistula is reviewed. Patients could be classified as a function of site of fistula into 3 groups: I. urethrovaginal fistula (31%); II. cervicovaginal fistula (22%); III. vesicovaginal fistula (46%). Etiology was mainly obstetrical (94%), as was multiparity (69%). An associated lesion was detected in 11% of cases (uterine, ureteral and rectal). Surgery was performed after a minimum period of 3 months with the following results. Type I fistulae, using a low approach and requiring urethral refection, showed good results in only 53% of cases. Type II fistulae, usually treated through a low approach (80%), were relieved in 80% of cases, with the reservation that reinforcement of bladder neck was often necessary. Type III fistulae, treated by a high (60%) or low (40%) approach were nearly always corrected (98%). In 2 cases of destroyed urethra unable to benefit from urethral plastic surgery, bladder repositioning with continent cystostomy was satisfactory. 72 cases with irrecuperable destroyed bladder received definitive high diversion: 34 Coffey, 5 Bricker, and since 1975, 33 continent ileocecal bladders using Benchekrouns' technique.
