The middle fossa approach and extended middle fossa approach, also known as the anterior transpetrosal approach, are cranial base techniques for addressing small vestibular schwannomas, medial temporal bone lesions, midbasilar trunk aneurysms, and selected petroclival lesions. Objective: To provide an outline of a number of technical nuances that are important to correct application of these [...]

Various techniques of cerebral bypasses are used to treat aneurysms and tumors. OBJECTIVE: To study long-term clinical and radiological outcome of various bypass types and to analyze techniques used in the management of long-term graft problems. METHODS: A consecutive series of patients who underwent revascularization during a 5-year period were analyzed for indications, graft patency, [...]

Radiosurgery is widely used to treat deep eloquent arteriovenous malformations (AVMs). OBJECTIVE: To evaluate how anatomic location, AVM size, and treatment parameters define outcome. METHODS: Retrospective analysis of 356 thalamic/basal ganglia and 160 brainstem AVMs treated with gamma knife radiosurgery. RESULTS: Median volume was 2 cm3 (range, 0.02-50) for supratentorial and 0.5 cm3 (range, 0.01-40) [...]

Romani, Rossana MD, PhD*; Laakso, Aki MD, PhD*; Kangasniemi, Marko MD, PhD‡; Niemelä, Mika MD, PhD*; Hernesniemi, Juha MD, PhD* Various surgical approaches for the removal of tuberculum sellae meningiomas (TSMs) have previously been described. OBJECTIVE: To assess the reliability and safety of the lateral supraorbital (LSO) approach to remove TSMs. METHODS: We identified all [...]

Intravascular ultrasonography (IVUS) has been used for guiding intravascular stent placement in interventional cardiology. OBJECTIVE: To evaluate the feasibility of aneurysm embolization by using detachable coils under IVUS guidance. METHODS: IVUS-guided embolization in conjunction with fluoroscopic imaging and subsequently alone were performed in a silicone model with a side wall aneurysm. IVUS-guided embolization in conjunction [...]

Objective. We examined the risk factors for cage retropulsion after posterior lumbar interbody fusion (PLIF) performed for patients with degenerative lumbar spinal diseases. Summary of Background Data. Although PLIF is a widely accepted procedure, problems remain regarding perioperative and postoperative complications. There are few reported studies identifying specific risk factors for cage retropulsion, one of [...]

Chordomas of the skull base are locally aggressive neoplasms for which maximal surgical resection confers prolonged survival. OBJECTIVE: To present the largest consecutive surgical series of cranial base chordomas to date, including complications, functional outcome, and overall (OS) and recurrence-free survival (RFS) in early and late eras of our experience. METHODS: From 1988 to 2011, [...]
