Correção endovascular de pseudoaneurisma toracoabdominal em paciente com Doença de Behçet / Endovascular repair of a thoracoabdominal pseudoaneurysm in a patient with Behçet’s disease

A Doença de Behçet é uma doença inflamatória caracterizada por úlceras genitais e orais recorrentes, uveítes e lesões cutâneas. O envolvimento arterial é raro, sendo mais comuns as degenerações aneurismáticas do que as oclusivas. Neste caso clínico, paciente do sexo feminino, em tratamento de doença de Behçet havia 20 anos, iniciou com dor abdominal progressiva por dois meses, com piora súbita importante, foi submetida à tomografia computadorizada, que mostrou pseudoaneurisma toracoabdominal. A paciente foi submetida a tratamento endovascular com sucesso.

Behçet’s disease is an inflammatory disease characterized by recurrent oral and genital ulcers, uveitis and skin lesions. Arterial involvement is rare, but when present aneurysmal degeneration is more common than occlusive disease. This report describes the clinical case of a female patient who had been receiving treatment for Behçet’s disease for twenty years before presenting with abdominal pain that progressed for 2 months before suddenly worsening significantly. A CT scan revealed a thoracoabdominal pseudoaneurysm. She was successfully treated with endovascular repair.

Intracranial pseudoaneurysm after intracranial pressure monitor placement.

Traumatic intracranial pseudoaneurysms are a rare but severe complication following arterial injury. Pseudoaneurysm formation can occur secondary to blunt or penetrating trauma or iatrogenic injury. We report a case of traumatic pseudoaneurysm secondary to placement of an intracranial pressure (ICP) monitor. A 27-year-old man was involved in a motorcycle accident resulting in multiple intracranial hemorrhages. The patient underwent craniectomy and placement of an ICP monitor. 17 days later he developed dilation of his left pupil, with imaging demonstrating a new hemorrhage in the vicinity of the previous ICP monitor. A cerebral angiogram confirmed a left-sided distal M4 pseudoaneurysm which was treated by n-butyl cyanoacrylate embolization. Intracranial pseudoaneurysm formation following neurosurgical procedures is uncommon. Delayed intracranial hemorrhage in a region of prior intracranial manipulation, even following a procedure as 'routine' as placement of an ICP monitor, should raise the suspicion for this rare but potentially lethal complication.
