Abstract
Bronchial artery embolization (BAE) is a well-accepted method technique to control hemoptysis. In recent years, superselective embolization with a coaxial microcatheter system has been reported as a way to avoid spinal injury. Between April 1994 and July 1997, superselective BAE using gelatin sponge and metallic coils as occlusive material was performed in 41 patients. They included 27 men and 14 women aged 31-76 years (average 58.3). Immediate control of hemoptysis was achieved in 37 of 41 patients (90.4%) by BAE. On longterm follow period (average 36.1 month) of 35 patients with immediate successful BAE, 5 patients (14.3%) had bloody sputum but not hemoptysis. 8 patients (23.9%) had hemoptysis and underwent embolization therapy again.
