In this study, we report a case of catastrophic propeller brain injury with large scalp defect treated with omental flap reconstruction.A 62-year-old man was accidentally caught in a powered paraglider propeller during maintenance. The rotor blades impacted the left part of his head. On arrival at the hospital, he presented with a Glasgow Coma Scale score of E4V1M4. On some areas on his head, skin was noticeably cut off, and the brain tissue out-slipped through an open skull fracture. Continuous bleeding from the superior sagittal sinus (SSS) and the brain surface was observed during emergency surgery. Massive bleeding from the SSS was controlled using a number of tenting sutures and hemostatic agents. We evacuated the crushed brain tissue and coagulated the severed middle cerebral arteries. Dural plasty using the deep fascia of the thigh was performed. The skin defect was closed using an artificial dermis. The administration of high-dose antibiotics has failed to prevent meningitis. Moreover, the severed skin edges and fasciae were necrotic. Plastic surgeons performed debridement and vacuum-assisted closure therapy to promote wound healing. Follow-up head computed tomography revealed hydrocephalus. Lumbar drainage was performed; however, sinking skin flap syndrome was observed. After removing the lumbar drainage, cerebrospinal fluid leakage occurred. We then performed cranioplasty with a titanium mesh and omental flap on day 31. After the surgery, perfect wound healing and infection control were achieved; however, severe disturbance of consciousness remained. The patient was transferred to a nursing home. Primary hemostasis and infection control are mandatory. An omental flap has been determined to be effective in controlling infection by covering the exposed brain tissue.

Posterior inferior cerebellar artery (PICA) aneurysms often require cerebral vascular reconstruction for surgical treatment because of their characteristic morphology. Despite its potential complications, the occipital artery-to-posterior inferior cerebellar artery (OA-PICA) bypass is a typical treatment because of its versatility. Although a few cases of intracranial-to-intracranial bypass have been reported, this type of vascular reconstruction is only regarded as an alternative to the OA-PICA bypass because of the uncertainty of bypass feasibility and potential risk of ischemic complications. In this article, we report a case of proximal PICA ruptured aneurysm that was treated with a PICA-to-PICA (PICA-PICA) bypass. A 79-year-old man presented with a chief complaint of sudden, severe headache and disturbances in consciousness. Radiological examination revealed a right proximal PICA fusiform aneurysm. The patient had many systemic disorders such as microscopic polyangiitis and steroid-induced diabetes mellitus that could have caused wound dehiscence and cerebrospinal fluid (CSF) leakage. We performed the PICA-PICA bypass and trapping surgery rather than the OA-PICA bypass to avoid skin problems and CSF leakage. The postoperative course was uneventful, and the patient was discharged on day 64 without any neurological disorders. In comparison with the OA-PICA bypass, the PICA-PICA bypass is less likely to cause CSF leakage and skin complications, although it carries the risk of specific ischemic complications and requires advanced surgical techniques. For some patients with systemic disorders, the PICA-PICA bypass could be an optimal treatment option for proximal fusiform PICA aneurysms rather than as an alternative to the OA-PICA bypass.
