BACKGROUND AND PURPOSE: The role of corticosteroids in the treatment of patients with aneurysmal subarachnoid haemorrhage (SAH) has remained controversial for decades. Recent studies have suggested that the administration of corticosteroids in SAH patients is associated with favourable outcomes. Given their significant adverse effects, it is essential to identify those patients who will benefit from treatment with corticosteroids. METHODS: A retrospective analysis of a prospectively collected cohort (n = 306) with SAH who were treated by microsurgical clipping or endovascular intervention was performed...

Background Autologous breast reconstruction has been noted in the literature to provide superior aesthetic outcomes and patient satisfaction. Additionally, free perforator flap tissue transfer has the potential for lower abdominal donor site morbidity. However, it has been noted that the percentage of women who are undergoing autologous breast reconstruction in the United States is decreasing. Factors related to the technical difficulty, prolonged operative times, and decreasing reimbursement have been implicated as the causes...

BACKGROUND: Pilocytic astrocytomas (PAs) are slow growing neoplasms and usually located at the cerebellum. There has been certainty regarding the truthful benefit of surgical resection for patients with PA. Gross total resection (GTR) of PAs, especially those being situated in deep regions, remains a surgical challenge. Generally, they are considered as benign and usually develop in young patients. PAs, belonging to WHO I can be cured by radical resection. The patients with PA have excellent prognosis if complete resection can be conducted...

BACKGROUND AND OBJECTIVES: Prior radiotherapy leads to increased wound complication rates for microsurgical reconstruction of pharyngolaryngeal (PL) defects. Incorporating vastus lateralis muscle together with anterolateral thigh flap (ALT) skin in defect reconstruction is useful in protecting vital structures and reinforcing irradiated neck skin and suture lines. This study shows the utility of the musculocutaneous ALT (MC ALT) in PL reconstruction in previously irradiated patients. METHODS: A single-surgeon, retrospective chart review of all patients with defects of the PL region where an MC ALT was used for reconstruction from February 2014 to May 2016...

BACKGROUND: Induced hypotension (IH) had been used for decades in neurosurgery to reduce the risk for intraoperative blood loss and decrease blood replacement. More recently, this method fell out of favor because of concerns for cerebral and other end-organ ischemia and worse treatment outcomes. Other contributing factors to the decline in its popularity include improvements in microsurgical technique, widespread use of endovascular procedures, and advances in blood conservation and transfusion protocols...

The giant, single-celled organism Stentor coeruleus has a long history as a model system for studying pattern formation and regeneration in single cells. Stentor [1, 2] is a heterotrichous ciliate distantly related to familiar ciliate models, such as Tetrahymena or Paramecium. The primary distinguishing feature of Stentor is its incredible size: a single cell is 1 mm long. Early developmental biologists, including T.H. Morgan [3], were attracted to the system because of its regenerative abilities-if large portions of a cell are surgically removed, the remnant reorganizes into a normal-looking but smaller cell with correct proportionality [2, 3]...

INTRODUCTION: Optimal acoustic neuroma (AN) management involves choosing between three treatment modalities: microsurgical excision, radiation, or observation with serial imaging. The reported in-hospital mortality rate of surgery for AN in the United States is 0.5%. However, there has yet to be a nationwide examination of the AN surgery mortality rate encompassing the period beyond initial hospital discharge. METHODS: The National Cancer Data Base (NCDB) from 2004 to 2013 identified AN patients receiving surgery...

OBJECTIVE Fusiform cerebral aneurysms represent a small portion of intracranial aneurysms; differ in natural history, anatomy, and pathology; and can be difficult to treat compared with saccular aneurysms. The purpose of this study was to examine the techniques of treatment of ruptured and unruptured fusiform intracranial aneurysms and patient outcomes. METHODS In 45 patients with fusiform aneurysms, the authors retrospectively reviewed the presentation, location, and shape of the aneurysm; the microsurgical technique; the outcome at discharge and last follow-up; and the change in the aneurysm at last angiographic follow-up...

OBJECTIVE Advanced microsurgical techniques contribute to reduced morbidity and improved surgical management of meningiomas arising within the cerebellopontine angle (CPA). However, the goal of surgery has evolved to preserve the quality of the patient's life, even if it means leaving residual tumor. Concurrently, Gamma Knife radiosurgery (GKRS) has become an acceptable and effective treatment modality for newly diagnosed, recurrent, or progressive meningiomas of the CPA. The authors review their institutional experience with CPA meningiomas treated with GKRS, surgery, or a combination of surgery and GKRS...

INTRODUCTION: A patient with a small (<3cm) intracranial meningioma can be either observed or treated. Treatment can be either radiosurgery or microsurgery if and when progression of the tumor occurs. We have compared the local tumor growth control and recurrence-free survival (RFS) of microsurgical resection and radiosurgery in small intracranial meningiomas, and we have identified the predictors of unfavorable outcome. MATERIALS AND METHODS: Retrospective review (2005-2016) of 90 consecutive patients with intracranial meningiomas who underwent either microsurgery (n=31) or gamma knife radiosurgery (GKRS, n=59) was done...

PURPOSE: Giant pediatric intracranial tumor (GPIT) remains to be a challenging disease with high morbidity and mortality. METHODS: The clinical data of 60 patients under 18 years of age operated on with GPIT (≥5 cm in diameter) were retrospectively analyzed. RESULTS: Gross total resection was achieved in 46 cases (77%) and subtotal resection was obtained in 14 cases (23%). Ninety percent (47/52) of the cases with obstructive hydrocephalus were resolved remarkably and only 10% (5/52) of the patients needed a ventriculoperitoneal shunt after tumor resection...
