Abstract
Here we investigated the changes in utility and limits of combined microsurgical and endovascular treatment for complex cerebrovascular disease before and after the introduction of the hybrid operating room (HOR) in our department. Since 2006, a total of 17 patients (cerebral aneurysm in 12, cerebral arteriovenous malformation in 5) underwent integrated microsurgery with endovascular treatment. In 3 of 11 patients treated before the introduction of HOR, certain problems such as time consumption during patient transfer, disconnected workflow, and complicated operation due to poor quality of support equipment occurred. In contrast, all 6 operations in the HOR were uncomplicated. All therapeutic steps including anesthesia management were planned in a single session. In conclusion, HOR provides a safe and smooth workflow in combined microsurgical and endovascular treatment for complex cerebrovascular diseases.
