[Therapeutic arterial embolization in hemobilia. Apropos of 3 cases].

Three patients with bleeding into the bile ducts were explored by angiography. Two of them (severe post-operative bleeding and following needle-biopsy of the liver) were completely cured by highly selective arterial embolus production. No definite diagnosis was established in the third case (liver angioma with large artero-portal fistula). It can be seen from these observations, that angiography is essential in patients with bleeding into the bile ducts. The reason is not to establish the diagnosis but to find the precise location of the lesion and, under certain conditions, to apply radical treatment by highly selective arterial embolus production.
