In the last years, a new technique for pelvic fixation using 'sacral alar-iliac' screws has been proposed as an alternative to the classic 'iliac wing' screws and the old Galveston technique. ⋯ 'Sacral alar-iliac' screws provide several advantages in relation to pelvic fixation with iliac bolts such as: better alignment with the rods, use of a 'low-profile' screw, and fixation of the sacroiliac (SI) joint, which avoids postoperative SI joint-related pain.

Review Case ReportsSurgery for contralateral acute epidural hematoma following acute subdural hematoma evacuation: five new cases and a short literature review.
The occurrence of a contralateral acute epidural hematoma (AEDH) following removal of an acute subdural hematoma (ASDH) is a rare but nearly devastating postoperative complication. Here, we describe a series of five patients with contralateral AEDH and provide a review of the literature to elucidate the characteristics and improve management of these patients. ⋯ Lower preoperative GCS score is an independent risk factor for prognosis of contralateral AEDH after ASDH. Postoperative management should include assessment of AEDH in patients treated for contralateral skull fractures and who experienced intraoperative acute brain swelling. We recommend early decompression with a burr-hole craniotomy, immediately followed by a decompressive craniectomy. This strategy provides gradual decompression, while advancing the initial surgical time and preventing the suddle decreased tamponade effect. As such, it may help decrease the risk of contralateral AEDH associated with decompression.

Review Case ReportsSTA-ACA bypass using the contralateral STA as an interposition graft for the treatment of complex ACA aneurysms: report of two cases and a review of the literature.
Bypass surgery has been used as a remedy for the complex cerebral aneurysm, which was unsolved with the clipping method. However, little has been reported about bypass options for anterior cerebral artery (ACA) aneurysms. ⋯ To achieve complete obliteration of the aneurysm, we performed a superficial temporal artery (STA)-ACA bypass using contralateral STA as interposition grafts with endovascular trapping without any ischemic events. These cases show that STA-ACA bypass using contralateral STA interposition graft is a feasible option to maintain blood supply to the ACA territory if a proximal ACA lesion requires trapping.

ReviewVasospasm after spontaneous angiographically negative subarachnoid hemorrhage.
Vasospasm, delayed infarcts and clinical deterioration due to delayed cerebral ischemia (CD-DCI) following digital subtraction angiography (DSA)-negative, spontaneous subarachnoid hemorrhage (SAH) are infrequently and inconsistently described in the literature. ⋯ Although they are seen less frequently in patients with DSA-negative spontaneous SAH, vasospasm, delayed infarcts and CD-DCI do occur and may require endovascular therapy. Risk factors include a diffuse hemorrhage pattern and higher Hunt-Hess grade.

ReviewWhat is a reasonable surgical procedure for spinal extradural arachnoid cysts: is cyst removal mandatory? Eight consecutive cases and a review of the literature.
Spinal epidural arachnoid cysts (EAC) are rare and may present with myelopathy, which can be completely curable with surgery. The majority of investigators believe that the repairment of dural defect is important to treat EAC. However, the necessity of excising EACs remains controversial. The purpose of this study was to find a reasonable surgical technique for treatment of EACs after considering the clinical outcome, recurrence, and complications. ⋯ Total excision of EACs may have little benefit in terms of cyst recurrence and clinical outcome. The procedure for EAC resection carries a risk of complications such as kyphosis. If EAC resection is performed, we suggest that a tailored short-level laminotomy be used to allow for the repair of dural defects. Particularly in patients with small EAC, a partial hemilaminectomy with dural defect repair may be a possible method to reduce complications.
