Objectives: Superficial temporal artery (STA) to middle cerebral artery (MCA) bypass surgery is a common treatment for preventing cerebral ischemia in patients with intracranial artery stenosis. The aim of this study was to analyze the surgical outcomes of the STA-MCA bypass procedure, particularly with regard to the invasiveness of targeted bypass (TB) with preoperative planning using Amira software.
Methods: Consecutive patients with single STA-MCA bypass performed by a single neurosurgeon from January 2019 to May 2022 were included. The clinical parameters of seven TB patients were compared with those of 11 patients treated with the conventional method (CM).
Results: Compared with CM patients, TB using Amira software patients had a shorter scalp incision (median [interquartile range]=11.2 [9.7-12.7] cm vs. 16.9 [16.0-17.7] cm, respectively; =0.004], smaller craniotomy size (11.8 [11.5-14.4] cm vs. 20.9 [17.1-22.2] cm, respectively; =0.01], shorter surgery duration (201 [195-218] min vs. 277 [229-310] min, respectively; =0.003], and less intraoperative bleeding (10 [10-20] g vs. 23 [20-50] g, respectively; =0.033]. However, there were no differences in surgical complications between the two groups.
Conclusions: Detailed preoperative evaluation using Amira software can reduce the invasiveness of the STA-MCA bypass procedure.

The bifurcation of the middle cerebral artery (MCA) is one of the most common sites for the formation of cerebral aneurysms, presenting significant challenges for surgical management. A primary concern in this area is the recurrence of aneurysms following surgical clipping, which necessitates a thorough investigation of the contributing factors. This study examined all cases of rebleeding from previously clipped MCA aneurysms among 195 surgically treated patients over an 11-year period.

Revascularization surgery for moyamoya disease poses risks of complications, requiring appropriate management. Although precise prediction is difficult, the systemic immune-inflammation index is a calculable marker that reflects systemic inflammatory conditions. We aimed to investigate the association between postoperative complications and the systemic immune-inflammation index.

Pediatric patients with moyamoya disease frequently show rapid progression with a high risk of stroke. Indirect revascularization is widely accepted as a surgical treatment for pediatric moyamoya disease, but it does not augment cerebral blood flow immediately, which leaves patients at risk for stroke peri-operatively. This delay in flow augmentation may make adding direct bypass the better option.

Ischemic stroke is one of the major emergency diseases leading to death and disability worldwide, characterized by its acute onset and the urgent need for prompt medical intervention to reduce mortality and long-term disability. Chronic terminal internal carotid artery and/or middle cerebral artery occlusion (CTI/MCAO) is an important subtype of intracranial artery occlusive disease. The superficial temporal artery-to-MCA (STA-MCA) bypass has been proposed to improve cerebral blood flow (CBF) and cerebrovascular reserve (CVR), potentially enhancing neurological outcomes.

Background: Anemia is considered a risk factor for cardiovascular disease. However, there is little evidence regarding the relationship between hemoglobin (HB) and cerebral infarction after revascularization in patients with moyamoya disease (MMD). This study aimed to explore the relationship between postoperative cerebral infarction and HB in patients with MMD and to establish a predictive model.
