Infratentorial Cerebral Cavernous Malformation May be a Risk Factor for Symptomatic Bleeding and Precocity of Symptoms: A Multicenter, Propensity Score Matched, Case-Control Study.

Background: Cerebral Cavernous Malformation (CCM) is one of the most common types of vascular malformation of the central nervous system. Intracerebral hemorrhage, seizures, and lesional growth are the main clinical manifestations. Natural history studies have tried to identify many risk factors; however, the clinical course remains highly unpredictable.

Superficial vs combined cervical plexus block for carotid endarterectomy: a prospective, randomized study.

Background: 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.

Methods: A total of 125 patients submitted to elective CEA were randomized into 2 groups: the first group was submitted to superficial cervical block and the second group to combined (superficial plus deep) cervical block.

Results: No significant difference in anesthetic quality was observed between the 2 types of blocks.

Unilateral pterional approach to bilateral aneurysms of the middle cerebral artery.

Background: The aim of the present study was to evaluate the technical viability of the unilateral pterional approach to simultaneously treat symmetrical bilateral aneurysm (mirror image) of the middle cerebral arteries (SBAMCA) and to determine the morbidity and mortality rates of this approach.

Methods: Forty-six patients with SBAMCA underwent unilateral pterional craniotomy within a period of 9 years. Most patients were women (24, 80.

Multifocal osteoclastoma of the skull: case report.

We describe the case of a 35 years old man with a nonspecific complaint of a slow growing solid mass in the frontal region. Radiological exams evidenced two more lesions : in the superior and lateral walls of the orbit. Treated with total excision of the lesions and a cranioplastic procedure at the same act, with favorable outcome.

[Occlusion of the common carotid artery treated with a subclavian-internal carotid artery bypass].

We describe the case of a 62 years old woman with several transient isquemic attacks. The neuroradiological study demonstrated occlusion of the common carotid artery with revascularization of the internal carotid artery by anastomosis with the inferior thyroid artery and an aneurysm of internal carotid artery at the emergency of the anterior choroidal artery. The patient was treated with a bypass between the subclavian artery and the internal carotid artery with complete regression of the symptoms.
