We present two cases of traumatic aneurysms developing during aneurysmal surgery. The aneurysms were clipped without difficulty in both anterior communicating aneurysmal cases. To prevent the vasospasm, bypervolemic theraphy was begun and hypertension was induced postoperatively. The postoperative rebleeding occured within two weeks after initial aneurymal clipping in both cases. New aneursms developed near the clipped anterior communicating aneruysms ; A1 in one case, A2 in the other case. Minor arterial injury was considered to be the main cause of theses new aneurysmal formation and the hemodynamic stress induced by hypertension and hypervolemic therapy might contribute to the development of new aneurysms.
Key Words: Traumatic aneurysm; Hemodynamic stress; Therapy clipping; Minor arterial injury
