Percutaneous treatment of an intraorbital arteriovenous malformation using a transvenous approach: A case report.

Intraorbital arteriovenous malformations (AVMs) are extremely rare, and their actual prevalence is unknown. There is no consensus regarding the best treatment options, and the treatment is usually challenging, involving endovascular and other surgical procedures. Herein, we report the case of a patient diagnosed with an intraorbital AVM, presenting with thrombosis and hemorrhage, with rapidly progressive proptosis, chemosis, ophthalmoparesis, and vision loss.

The Dilemma of Anticoagulating Patients with Cerebral Venous Thrombosis Who Underwent Decompressive Craniectomy.

Background: Cerebral venous thrombosis is an uncommon subtype of cerebrovascular accident. The appropriate time interval between decompressive craniectomy and the onset of anticoagulation in patients with cerebral venous thrombosis is a controversial topic among neurosurgeons, neurologists, and intensivists.

Case Description: We present a brief clinical case report of a female patient who underwent decompressive craniectomy.

Cervical carotid pseudoaneurysm: A carotid artery stenting complication.

Background: As carotid artery stenting becomes increasingly used, more complications are likely to occur. We present a case of Staphylococcus septicemia and pseudoaneurysm arising in the neck portion of the carotid artery after stenting.

Case Description: A 51-year-old man was admitted with mild left hemiparesis.

Bridge-therapy with enoxaparin in the preoperative period of endarterectomy.

Cervical clot is one of the complications of endarterectomy. This risk may be higher in patients using aspirin or clopidogrel. On the other hand, stroke may occur if the medication is interrupted before surgery.

[Clinical and interventional revascularization in the acute ischemic stroke: national opinion].

The Brazilian Stroke Society constituted a committee composed by specialists from different areas of Brazil that emitted a viewpoint called "National Opinion," considering the interventional procedures and thrombolysis in the treatment of the acute ischemic stroke. This study presents the conclusions of this committee.

[Cerebral Aspergillus abscess in immunocompetent patient].

We report an unusual case of brain aspergillosis with multiple recurrent abscess in a 40 year-old immunocompetent woman, with good therapeutical outcome. The patient presented a subarachnoid hemorrhage caused by a ruptured pericallosal artery aneurysm and was submitted to a craniotomy for aneurysm surgery. Five months later, she developed multiple Aspergillus cerebral abscess.
