Abstract:
Traumatic pseudoaneurysms (TPA) were surgically produced in the right common carotid artery of 24 rabbits. Three to four weeks later the survived rabbits 16 were randomly divided into 3 groups: (1)control group; (2)treatment group with TPAs embolized with microcoils(MC); (3)treatment group with occlusion of the by parent artery with MC. Three months after embolizaton, the TPAs were examined by digital subtraction angiography (DSA). The results showed that the TPAs embolized with MC were proved to be completely occluded, and the parent artery remained patent. Histopathological examination showed that TPAs were replaced by a mass of scar tissues. In the rabbits with occlusion of the parent artery embolization with MC, the TPA also disappeared. However, all the untreated rabbits died of rupture of TPAs. Statistic analysis showed that both methods of treatment were effective in the treatment of TPA.
