Percutaneous transhepatic cholangiography (PTC) and selective visceral angiography (SVA) were performed in 50 patients with suspected or known obstructive jaundice.
In 3 cases (1 tumor) both examinations failed to reveal the correct diagnosis.
In most of the cases each examination yielded important information, often complementary to that of the other.
Transhepatic cholangiography is suitable for revealing the site of obstruction and the anatomy of the bile ducts. Selective angiography provides information of the origin and extent of the lesion as well as possible hepatic metastases and involvement of nearby structures. Both examinations can give information, often complementary, on the nature of the lesion.
The authors recommend the combined use of PTC and SVA in all patients with known or suspected obstructive jaundice not evidently due to choledocholithiasis, provided that the general condition of the patient allows laparotomy.
