Comparative Study
Clinical characteristics and surgical results of patients with cerebral arteriovenous malformations.
Cerebral arteriovenous malformation (AVM) is a common vascular disease in neurosurgery, and the indication for alternative treatments remains controversial. In a review of a series of 2086 patients with AVMs, the clinical characteristics and surgical results were assessed. ⋯ Cerebral AVM is one of the important reasons for spontaneous intracranial hemorrhage in patients younger than 40. Spetzler-Martin grading system is helpful to predict the surgical risk. Microsurgical technique has made surgical treatment safer and become the best choice for patients with cerebral AVM.

Early or ultra-early surgery for patients in poor neurological condition (Hunt and Hess grade IV or V) after ictus of aneurysmal subarachnoid hemorrhage is increasingly reported to prevent early rebleeding. To prevent any rebleeding after hospital admission, we have treated patients with poor-grade aneurysm during the same session as when diagnostic angiography is performed ("one-stage embolization"). The aim of the present study is to determine whether this treatment modality is a viable management option for this group of patients. ⋯ We achieved promising results by using one-stage embolization to prevent ultra-early rebleeding followed by aggressive resuscitation. The active involvement of the endovascular team from the stage of diagnostic angiogram is a prerequisite for this treatment strategy.

Resection of lesions in eloquent areas of the brain are sometimes best done with the patient awake. An awake patient provides neurological feedback as the lesion is resected. This increases the chances of a complete resection without leaving a patient neurologically devastated. Unfortunately, this procedure is not always well tolerated by the patient. ⋯ The addition of dexmedetomidine to our technique improves safety and comfort for patients undergoing awake craniotomy.

Tuberculosis of the craniovertebral junction (CVJ) is extremely rare. However, recent evidence suggests that the incidence of this condition may be increasing. The diagnosis is often difficult despite advances in imaging using magnetic resonance imaging. The transoral approach to the anterior CVJ provides excellent access to this region, has low mortality and morbidity, and enables biopsy of lesions and decompression of the neuraxis. Management of associated atlantoaxial instability, with regard to timing and method of stabilization, is controversial. ⋯ Although CVJ tuberculosis is a rare disease, the outcome of treatment is good. Antituberculous drug therapy remains the mainstay of treatment after confirming the diagnosis. The surgical management options include transoral decompression with or without posterior fusion, depending upon the presence and persistence of atlantoaxial instability.

Randomized Controlled Trial Comparative Study Clinical Trial
Superficial vs combined cervical plexus block for carotid endarterectomy: a prospective, randomized study.
The present study compares combined and superficial cervical plexus block in patients submitted to carotid endarterectomy (CEA) in terms of anesthetic efficacy, satisfaction of the patient and surgeon, complications resulting from the type of anesthesia, and final outcome. ⋯ Superficial cervical anesthetic block shows the same efficacy as combined block, with the surgical conditions being closely similar. The incidence of complications related to the anesthetic technique is higher for combined block. The type of block does not influence the final outcome of the patients.
