Intraoperative rupture of blood blister-like aneurysm: a case report and review of literature

Blood blister-like aneurysms (BBLAs) are aneurysms from the non-branching sites of the internal carotid artery (ICA).Though rare lesions,they pose a high risk of intraoperative aneurysmal rupture.Definite treatment of these types of aneurysms has been debatable,but surgical approach is the ultimate rescue treatment.Microsuture of the intraoperative ruptured BBLA has been reported scarcely in literature,but no review of these cases has ever been reported.We here present our experience of a case of BBLA intraoperative rupture requiring microsuture of the ICA and conduct meticulous review of all similar cases.

Intracranial foreign body through the sagittal sinus: case report and review of literature

Objective:To investigate therapeutic effect of surgery that removes an intracranial foreign body through the intracranial sagittal sinus with help of intraoperative navigation and intraoperative fluorescein angiography.Methods:We performed operation on a patient with intracranial foreign body.Under guidance of intraoperative navigation,combined with intraoperative fluorescein angiography to avoid sagittal sinus damage,we opened the dura mater and removed the foreign body with minimally invasive technique.Results:Surgical positioning was very accurate with neuronavigation,intraoperative fluorescein angiography displayed the venous drainage along the sagittal sinus in order to prevent its rupture;the intracranial foreign body was removed successfully without any post-operative complications.Conclusion:Intraoperative navigation and intraoperative fluorescein angiography technologies to guide the removal of the foreign metal body inserted through the sagittal sinus have the following advantages:Accurate positioning,minimally invasive,reliable curative effect,quick postoperative recovery and overall fewer complications.
