Superficial temporal artery (STA) to middle cerebral artery (MCA) bypass is associated with several surgical problems. Despite the vascular patency and hemodynamic changes after the anastomosis, wound problems can be a major surgical complication. ⋯ These data suggest that the simple layering technique of the ITO dissection method can protect against contamination from bacteria and reduce postoperative surgical wound problems. Sealing of the galea aponeurotica (first protective barrier), including fibrous septa and loose areolar tissues, including the periosteal layer (second protective barrier), is an important factor to decrease the rate of scalp wound infection.

The development of secondary brain injury via oxidative stress after traumatic brain injury (TBI) is well known. Decorin (DC) inactivates transforming growth factor β1, complement system, and tumor necrosis factor α, which are related to oxidative stress and apoptosis. Consequently, the aim of the present study was to evaluate the role of DC on TBI. ⋯ The results of the present study showed that DC inactivates transforming growth factor β1 and protects the brain tissue and neuronal cells after TBI.

Incomplete repair of the dura mater may result in numerous complications such as cerebrospinal fluid leakage and meningitis. For this reason, accurate repair of the dura mater is essential. In this study, the effect of systemic and local supplementation of l-arginine on dural healing was evaluated. ⋯ The systemic supplementation of l-arginine may accelerate dural healing by increasing the level of granulation tissue formation, collagen deposition, and vascularization.
