Surgical treatment of a vertebral artery aneurysm in the acute stage using temporary clipping of vessels is reported in this paper. The results in twenty-nine cases, including some cases of chronic stage surgery, were 20 excellent, six good, one fair, none poor and two deaths. On the other hand, the results in 13 cases operated on within one week after the onset of symptoms were nine excellent, three good, one fair, none poor and no deaths. Among these, there was no mortality but one case of morbidity. In the morbidity case, motor paresis, caused by the vasospasm in anterior circulation appeared one week after surgery.
In patients with a posterior circulation aneurysm, the incidence of vasospasm, which is the course of unfavorable outcome with severe ruptured aneurysms, is lower. These date are thought to indicate that surgery using temporary clipping may avoid premature rupture during surgery, which is the biggest trouble in acute stage surgery, and bring about favorable surgical result.
