ABSTRACT
Objective Experimentally to investigate the changes in vasospastic canine basilar arteries. Methods Vasospasm of basilar arteries was induced by double-injecting autologous blood into the brain cisterns. 28 adult mongrel dogs of both genders served as the subjects, of them 20 involved in experimental group and accepted the PTA treatment and the other 8 doges were in negative control group without any treatment. PTA was performed by a single inflation of balloon for 10 seconds at a peak pressure of 2.0 atmospheres. Angiography was re-performed at 30 day, 90 day and 300 day following PTA, respectively. The histologic changes were then evaluated using light and electron microscopy. Results Caliber of basilar arteries of all canines decompressed obviously, from 1.3 mm to 0.8 mm. In test group, PTA succeeded in 15 ones, with caliber of vasospastic basilar arteries enlarged obviously after PTA ( P
