Coil embolization of an unruptured intracranial aneurysm associated with Behcet's disease: case report

Superior Mesenteric Artery Vasculitis in Behçet's Disease: A Case Report and Literature Review

A 55-year-old male presented with abdominal pain that had begun about 5 days ago. Physical examination revealed oral aphtha, genital aphthosis, and pseudofolliculitis, and the patient was diagnosed with incomplete Behçet's disease (BD). Contrast-enhanced computed tomography (CECT) showed dilation of the superior mesenteric artery and mesenteric infiltration of inflammation, indicating vasculo-BD. The symptoms were improved by 3-day of intravenous methylprednisolone pulse therapy followed by oral prednisolone. A literature review suggested that vasculo-BD should be included as a differential diagnosis in cases with unexplained abdominal pain, arterial dilation, and mesenteric invasion, and CECT examination and steroid therapy should be considered.

Surgical Outcome of Cerebral Aneurysm Clipping Treated with Immunosuppressants: Report of 11 Cases and Review of the Literature

There are no reports on the outcomes of clippings in patients who receive immunosuppressants, for example, due to connective tissue diseases or following organ transplantation. We thoroughly reviewed these cases focusing on the perioperative management phase. The study included 11 patients with intracranial aneurysms who were taking immunosuppressants; between 2007 and 2014. We performed 12 clipping surgeries. Their clinical records were reviewed for age and gender, aneurysms' location and size, perioperative management of the immunosuppressive drugs, and surgical complications. The study included nine females and two males, aged between 52 and 71 years (mean 60.1 ± 8.5 years). The clinical presentation in five cases was subarachnoid hemorrhage (SAH); the aneurysm was incidentally diagnosed in six patients (7 aneurysms). The reasons for taking immunosuppressants were autoimmune disorder in nine patients and liver transplantation in two patients. Daily intake of oral immunosuppressants for the patients with liver transplantation was discontinued for 2-4 days, and no infectious complications were evidenced. The weekly course of immunosuppressive drugs for the patients with autoimmune disorder was continued in eight of nine patients. Caution must be exercised when considering the suitability of clipping for patients taking immunosuppressants, but surgery outcomes are generally favorable; when operative treatment is required, we believe it to be comparatively safe, if the perioperative management is conducted in close collaboration with the relevant departments.

Spontaneous Intra-Abdominal Hemorrhage Due to Rupture of Jejunal Artery Aneurysm in Behcet Disease: Case Report and Literature Review

Rupture of jejunal artery aneurysm is a very rare event resulting in life-threatening hemorrhage in Behcet disease (BD). We report a case of ruptured jejunal artery aneurysm in a 35-year-old patient with BD. The patient had a 1-year history of intermittent abdominal pain caused by superior mesenteric artery aneurysm with thrombosis. Anticoagulation treatment showed a good response. Past surgical history included stenting for aortic pseudoaneurysm. On admission, the patient underwent an urgent operation due to sudden hemorrhagic shock. Resection was performed for jejunal artery aneurysm and partial ischemia of intestine. The patient was diagnosed with BD, based on a history of recurrent oral and skin lesions over the past 6 years. Treatment with anti-inflammatory medications showed a good response during the 8-month follow-up.An increased awareness of BD and its vascular complications is essential. Aneurysms in BD involving jejunal artery are rare, neglected and require proper management to prevent rupture and death. To our knowledge, this is the first reported case of jejunal artery aneurysm caused by BD.

Successfully treated isolated renal artery pseudoaneurysm in a patient with Behçet's disease

Renal artery aneurysms and pseudoaneurysms are an uncommon clinical problem with a low incidence rate. They are abnormal dilatations of the vessel lumen with some different natures. However, the rupture of an aneurysm and pseudoaneurysm is the most dreaded complication because it causes death of the patient. There are many causes of renal artery aneurysm and pseudoaneurysm, including Behçet's disease; however, renal involvement in Behçet's disease is less frequent. We report a case of renal artery pseudoaneurysm induced by Behçet's disease and treated successfully with coil embolization. A 56-year-old woman with Behçet's disease presented with an incidental left renal artery pseudoaneurysm measuring 18 mm. We successfully performed endovascular treatment with coil embolization instead of surgical treatment.

Rapidly evolving large extracranial vertebral artery pseudoaneurysm in Behçet's disease: Case report and review of the literature

Behçet's disease is a multisystem chronic autoimmune disease of unknown etiology with a wide spectrum of symptoms and organ system involvement. Arterial manifestations, particularly of the extracranial vertebral arteries, are rare. We report an unusual case of an African American patient with Behçet's disease, who presented with bilateral spontaneous vertebral artery pseudoaneurysms. The patient underwent successful endovascular parent vessel occlusion with detachable coils and on follow-up had complete clinical and angiographic signs of recovery.

Onyx Embolization of Ruptured Intracranial Aneurysm Associated with Behçet's Disease

Introduction. Intracranial aneurysms associated with Behçet's disease (BD) are a rare occurrence. They are fragile, thin-walled pseudoaneurysms, which have high tendency to rupture and present a therapeutic challenge. Case Presentation. We report a 26-year-old male with BD presented with subarachnoid hemorrhage due to ruptured middle cerebral artery aneurysm. Additionally, two unruptured aneurysms were identified. He underwent endovascular embolization using Onyx with successful obliteration of the ruptured aneurysm. Medical therapy resulted in regression of one and resolution of the other aneurysms. Conclusion. We describe the first report of the application of Onyx for obliteration of ruptured cerebral aneurysm in BD as a feasible and safe therapeutic option for patients who are not candidates for other techniques.

Recurrence of subarachnoid hemorrhage due to the rupture of cerebral aneurysms in a patient with Sjögren's syndrome. Case report

A 52-year-old woman with Sjögren's syndrome presented with multiple cerebral aneurysms, which resulted in recurrent subarachnoid hemorrhage (SAH) manifesting as severe headache. Computed tomography (CT) showed SAH. Cerebral angiography revealed aneurysms of the anterior communicating artery and the left middle cerebral artery. The necks of the aneurysms were successfully clipped. Postoperative course was uneventful and she was discharged without neurological deficit. Thirteen years later, she suddenly lost consciousness and was brought to our hospital. CT demonstrated recurrence of SAH. Cerebral angiography revealed cerebral aneurysms of the right internal carotid artery and the right middle cerebral artery. The clipped aneurysms were stable. The internal carotid artery aneurysm was successfully treated with endovascular coil embolization. However, she regained no neurological function and died. Patients with Sjögren's syndrome may develop cerebral aneurysm complicated with SAH.
