Segmental arterial mediolysis is a rare disease characterized by idiopathic noninflammatory vasculopathy involving small to medium arteries. Here, we report a case of ruptured cerebral and abdominal aneurysms, which were successfully treated using emergency endovascular coil embolization. ⋯ It is extremely rare for a subarachnoid and an abdominal hemorrhage to occur simultaneously during hospitalization. Here, owing to the vulnerability of the unaffected vertebral artery during the initial procedure, segmental arterial mediolysis was diagnosed.

Persistent trigeminal artery is the most frequent embryonic communication between the vertebrobasilar and carotid systems. To the best of our knowledge, posttraumatic trigeminal-cavernous fistula is rarely reported in the literature. ⋯ Even though preservation of the parent artery is generally considered a desirable goal in fistula treatment, in special cases such as Salzmann type 2 anatomy plus a unique fistulous orifice accompanied by external carotid-cavernous fistula, it is required to embolize the persistent trigeminal artery and cavernous sinus.

Three-column spinal osteotomies were developed to address severe and stiff kyphoscoliosis. However, the optimal choice of osteotomy in these patients is still unclear. This retrospective study aims to compare the outcomes and complications between grade 4 and grade 5 osteotomies in patients with severe and stiff thoracic kyphoscoliosis. ⋯ Similar clinical outcomes can be achieved with grade 4 and grade 5 spinal osteotomies. This may enrich the basis on moving down to a lower osteotomy grade when treating patients with severe and rigid thoracic kyphoscoliosis.

To evaluate the impact of cigarette smoking on the development of wound complications, including wound dehiscence, superficial infection, deep infection, or organ space infection, within the first 30 postoperative days in patients undergoing surgery for spondylolisthesis. ⋯ The rate of wound complications was not higher in smokers undergoing PLF alone, but was significantly higher in smokers who underwent interbody fusion. However, multivariate analysis identified smoking as an independent predictor of organ/space infection irrespective of fusion technique used.

Case Reports
Delayed Intraventricular Pneumocephalus Following Shunting for Normal-Pressure Hydrocephalus.
Pneumocephalus is usually seen in trauma or cranial surgery. It is rarely reported as a delayed complication of ventriculoperitoneal shunt placement for hydrocephalus secondary to trauma, tumor, or aqueduct stenosis. We describe a case of intraventricular pneumocephalus manifesting 10 months after placement of a shunt for normal-pressure hydrocephalus. ⋯ Pneumocephalus after shunting for NPH is rare and described as a complication only during the first 2 postoperative months. This case is unique, as the pneumocephalus developed 10 months after shunting. The combination of an occult, possibly congenital, skull base defect and the insertion of a shunt resulted in delayed intraventricular and intraparenchymal pneumocephalus.
