Fenestrated mini-clips have been reported as useful for treating dog ear-shaped remnant aneurysms, the small aneurysms to which the efferent artery adheres or is impeded by the surrounding neurovascular structure in the restricted operative corridor, because of the smaller clip head. Here, the alternative utility of fenestrated mini-clip was reported by mentioning the narrower clip blade. ⋯ In selected cases, application of a narrower bladed fenestrated mini-clip in the restricted space may be useful to preserve tightly adhering branch arteries, as well as efferent arteries.

Schizencephaly is a rare congenital central nervous system malformation characterized by linear, thickened clefts of the cerebral mantle. Recently, germline mutations in collagen type IV alpha 1 (COL4A1) have been reported to be a genetic cause of schizencephaly as a result of prenatal stroke. Patients with COL4A1 mutation demonstrate a variety of disease phenotypes. However, little is known about the potential complications of patients with COL4A1 mutations before and after neurologic surgery. ⋯ To our knowledge, malignant hyperthermia and cerebral venous thrombosis have not been reported in the literature in patients with COL4A1 mutations after surgery. Schizencephaly arising from COL4A1 mutations might be a disease prone to these adverse effects because this mutation is known to be associated with venous tortuosity, venous vulnerability, and muscle spasms due to basement membrane protein abnormalities. We need to better understand the wide spectrum of clinical phenotypes of COL4A1 mutations and potential complications in order to better manage surgery of patients with schizencephaly.

In clipping surgery, it can be advantageous to dissect an adherent artery from the aneurysmal dome to achieve complete clipping. Bypass surgery can be useful to reconstruct an adherent artery when dissection of the artery is technically difficult or risky. We report the effectiveness of tailor-made intracranial (IC)-IC bypass to reconstruct an adherent artery in clipping surgery for middle cerebral artery (MCA) aneurysms. ⋯ During clipping surgery for MCA aneurysms, tailor-made IC-IC bypass is one of the useful options to reconstruct tightly adherent branch arteries, especially when an external carotid artery graft has not been prepared in advance.

To investigate the position of the aorta relative to the spine in patients with de novo lumbar scoliosis (DLS). ⋯ Although the position of the aorta relative to the spine showed no significant difference between patients with DLS and normal subjects, great attention should still be paid to prevent DLS-induced aorta injury.

To develop and validate a risk-scoring model for predicting recurrent hypertensive cerebral hemorrhage (RHCH) occurring within 1 year after initial hypertensive cerebral hemorrhage and to facilitate preemptive clinical intervention for the prevention of secondary hemorrhage. ⋯ This model will help identify high-risk groups for RHCH in order to facilitate and improve preemptive clinical intervention.
