Abstract
We have experienced 4 patients who had aneurysms lacerated iatrogenically at their necks. In all cases, too steep shearing forces to the neck was the cause of neck lacerations, and closure of torn aneurysmal necks with 1 to several stitches under the complete occlusion of the parent arteries was effective.
One of the causes of neck lacerations is thought to be intraaneurysmal thrombosis of the aneurysm as well as the bursting of aneurysms that were plugged by thrombus at their rupture point. We experienced 11 such unusual aneurysms that the initial angiogram indicated did not exist or were small. Lowering the intraaneurysmal pressure by temporary clipping is necessary to prevent neck laceration.
