The development of postcraniotomy hematoma (PCH) after surgery for acute traumatic subdural hematoma (aSDH) has been associated with an increased risk of a poor outcome. The risk factors contributing to PCH remain poorly understood. Our aim was to study the potential risk factors for PCH in a consecutive series of surgically evacuated patients with aSDH. ⋯ The results suggest that alcohol inebriation at the time of injury and hypocapnia during hospitalization are risk factors for the development of PCH.

The Pipeline Embolization Device (PED) has been increasingly used for the treatment of posterior circulation aneurysms. The purpose of the present study was to examine the clinical and angiographic outcomes of patients with vertebrobasilar aneurysms treated with the PED. ⋯ Our results show that Pipeline embolization of vertebrobasilar aneurysms is associated with acceptable occlusion and complication rates.

Takotsubo cardiomyopathy (TCM) and neurogenic pulmonary edema (NPE) are rare complications of an acute ischemic stroke. In particular, TCM and NPE following carotid endarterectomy (CEA) are extremely rare. In general, TCM- and NPE-associated ischemic strokes are caused by excess catecholamine release after sympathetic nervous stimulation following stroke onset, but the mechanism triggering this stimulation is still unknown. ⋯ We described a very rare case of TCM and NPE following CEA. The mechanisms of TCM and NPE involve excess catecholamine release after sympathetic nervous stimulation. Our findings suggest that surgery-associated transient ischemia and reperfusion injury to the left insular cortex stimulate sympathetic nerves.

Neurovascular training models include animal models, synthetics, or computer simulation. In vivo models are expensive and require significant resources. Synthetic/computer models do not reflect the elasticity of fresh vessels. We describe an endovascular and microsurgical training model using a chicken thigh/leg. ⋯ The chicken thigh/leg model provides training opportunities in microsurgical suturing, endovascular techniques for aneurysm obliteration, and microsurgical reconstruction of aneurysms. It combines affordability, time efficiency, and reproducibility. Further studies measuring improvement in technical aneurysm management and comparison with other training models are warranted.

To determine association between electrolyte disturbances and mortality in patients with severe traumatic brain injury. ⋯ Hypochloremia could be an important prognostic factor to determine mortality risk and to improve treatment in patients with severe traumatic brain injury.
