[Hypogastric artery embolization as a palliative treatment for bleeding secondary to intractable bladder or prostate...

Bleeding secondary to severe vesicoprostatic pathology (mainly neoplasic disease and radiation cystitis) may be a serious clinical management problem due to its morbidity and associated increased resources demand in the form of admissions, transfusions and other measures. We review a series of patients embolized for this purpose, its efficacy, tolerability and adverse events.

We review 8 patients who underwent hypogastric arteries embolization between July 1998 and December 2001, analyzing indications, efficacy and duration, tolerability, and consequences. Right femoral artery access was undertaken in all except one case that needed bilateral femoral accesses. Embolization was achieved by means of coils and particles. All procedures were performed under local anaesthesia.

9 procedures were performed in 8 patients. 3 patients presented with hematuria due to radiation cystitis, 3 from prostatic carcinoma, and 2 with urethrorragy from urethral relapses after cystectomy. 7/9 embolizations were effective achieving immediate complete or almost complete bleeding control; in one case control was partial; another one had limited or no effect. Selective embolization of distal arteries was performed in 3 cases; all the remainders underwent direct hypogastric trunk embolization sparing the superior gluteal artery. Effect lasted between 1 and 31 months. 4 patients died, 3 of them without haematuria, 1 because of an intercurrent disease, and the others from disease progression. 2 patients underwent posterior surgery, one due to recurrent haematuria, and the other, a case of urethral tumour, due to partial failure; partial cystectomy and urethrectomy were performed respectively. 2 patients needed administration of morphic derivatives after embolization, all the others were managed with magnesium metamizol. Only one patient referred mild transitory gluteal claudication.

Percutaneous arterial embolization is an effective instrument to treat patients with haematuria or urethrorragy and severe lower urinary tract pathology in whom curative treatments are not applicable due to their general status, life expectancy, or tumor status.
