[Therapeutic embolization for traumatic renal haemorrhage. 11 cases (author's transl)].

Therapeutic embolization by means of autologous clots or fragments of gelatin sponge was carried out in 11 patients suffering from renal haemorrhage of traumatic origin (5 needle biopsies, 3 surgical operations, 2 external traumas, 1 penetrating wound). Arterio-venous fistulae were present in 6 cases and arterial lesions in 5. Performed with a fine catheter, embolization was highly selective for the segmental arteries involved. The clinical symptoms disappeared within less than 12 hours in three patients, within 2 to 4 days in five and within 15 days in one. In two patients haematuria was only temporarily arrested ; a second embolization could be performed in one of these, but nephrectomy was required in the other.
