Right Ventricular Thrombus and Cerebral Artery Aneurysm in a Patient with Behçet's Disease

We report a 35-year-old woman referred to the Imam Ali Hospital, Kermanshah, Iran, in July 2014 for evaluation of postoperative dyspnoea after neurosurgery performed seven days previously for a ruptured cerebral artery aneurysm. She was known to have Behçet's disease with a history of recurrent oral and genital aphthous ulcers and uveitis. At referral, her symptoms included vertigo, dysarthria, palpitations and chest pain. Transthoracic echocardiography (TTE) revealed a large thrombus in her right ventricle outflow tract and open-heart surgery was performed eight days after the previous surgery to remove the clot. The postoperative period was complicated by transient acute renal failure, which resolved spontaneously. The patient was discharged 13 days after the cardiac surgery on warfarin, prednisolone, azathioprine and cyclophosphamide. Cyclophosphamide and azathioprine were discontinued after three months as the symptoms had completely resolved; however, prednisolone was continued due to recurrent uveitis. A 10-month follow-up TTE scan revealed no thrombus recurrence and treatment with warfarin and prednisolone was continued.
