AI Article Synopsis
- - Segmental arterial mediolysis (SAM) is a rare vascular disease that can lead to serious conditions like subarachnoid hemorrhage (SAH), as highlighted in a unique case of a ruptured blood blister-like aneurysm (BBA) in the internal carotid artery.
- - The patient initially experienced SAH, treated with high-flow bypass, but later suffered an intraperitoneal hemorrhage due to a rupture of a vascular aneurysm, leading to death despite medical interventions.
- - This case underscores the importance of recognizing the potentially dangerous link between SAM and cerebral aneurysms, emphasizing the need for careful monitoring in affected patients.
Article Abstract
Background: Segmental arterial mediolysis (SAM) is a rare non-atherosclerotic, noninflammatory vascular disease, characterized by mediolysis. We report an extremely rare case of subarachnoid hemorrhage (SAH) due to a ruptured blood blister-like aneurysm (BBA) of the internal carotid artery associated with SAM-related arteriopathy.
Case Description: We experienced a case of SAH followed by intraperitoneal hemorrhage that occurred 12 days after the SAH onset. SAH was caused by a ruptured BBA of the internal carotid artery, which was treated by trapping with high-flow bypass. Intraperitoneal hemorrhage was caused by a rupture of a posterior inferior pancreaticoduodenal artery (PIPDA) aneurysm, which induced hypovolemic shock resulting in death in spite of endovascular internal trapping. Postmortem pathologic examination revealed that the PIPDA pseudoaneurysm was due to SAM.
Conclusions: We should pay attention to the association of SAM, which is a potentially life-threatening pathology when treating cerebral BBAs.
