Hemangioblastoma is a benign and highly vascular tumor. Complete surgical resection of highly vascular tumor such as hemangioblastoma may be challenging due to excessive bleeding. Preoperative embolization of these lesions may decrease the intraoperative blood loss and facilitate excision. We report three cases of cerebellar hemangioblastomas that were embolized using Onyx.

I read with interest the paper entitled, “Perioperative complications of intraventricular neuroendoscopy: a 7-year experience” by Ganjoo et al (3). They reviewed perioperative complications in patients who had undergone elective neuroendoscopic surgery. The intraoperative complications were as follows: tachycardia, bradycardia, hypertension and bleeding. Hypothermia, delayed awakening and elect...

We conducted a prospective, double-blind clinical trial to evaluate the differences in operating time, intraoperative blood loss, postoperative pain at 3 hours and 1 week, and delayed (>24 hr) bleeding associated with ultrasonic harmonic scalpel tonsillectomy and conventional tonsillectomy. The study was carried out on 28 patients with recurrent tonsillitis and/or adenotonsillar hypertrophy who...

A 39-y-old man, who had an episode of pancreatic bleeding due to chronic pancreatitis, received total pancreatectomy with islet autotransplantation (TP with IAT). Intraoperative ultrasound (US) examination was done to detect transplanted islets and evaluate the quality of US imaging. Islet isolation from the resected total pancreas was performed and approximately 230,000 islet equivalents (IE...

PURPOSE We sought to document the difference in the vitreoretinal configuration of Stage 4 retinopathy of prematurity (ROP) in photocoagulated and treatment naive eyes undergoing vitrectomy and to correlate it with surgical complexity. METHODS Consecutive eyes posted for vitrectomy with Stage 4 ROP were documented preoperatively using a RetCam for the presence of peripheral traction (PT), pre...

Although bleeding is a common complication of surgery, routine laboratory tests have been demonstrated to have a low ability to predict perioperative bleeding. Better understanding of hemostatic function during surgery would lead to identification of high-risk patients for bleeding. Here, we aimed to elucidate hemostatic mechanisms to determine perioperative bleeding. We prospectively enrolled ...

Background/Introduction Management of preoperative antiplatelet therapy in coronary surgery is still variable among surgeons. Guidelines collide with prejudices: replacement of aspirin with low molecular weight heparin (LMWH) is still performed in many Centers due to a presumed minor risk of intraoperative bleeding, even though supporting evidences are weak and detrimental effects are well-desc...

BACKGROUND Intentional lowering of blood pressure helps to produce a desirably clean surgical field. Many drugs can be used to induce a hypotensive state, but due to their high potency and rapid effect, drugs that more easily and safely control the induction of hypotension are desirable. OBJECTIVES To investigate the effects of premedication with oral clonidine on intraoperative bleeding and ...

BACKGROUND The aim of this meta-analysis was to compare the long-term survival, mortality, morbidity and the operation-related events in patients with periampullary and pancreatic carcinoma undergoing pylorus-preserving pancreaticoduodenectomy (PPPD) and pylorus-resecting pancreaticoduodenectomy (PRPD). METHOD A systematic search of literature databases (Cochrane Library, PubMed, EMBASE and W...
