A 73-year-old woman had undergone hemiarch replacement with primary entry resection for treating acute type A dissection 6 years ago. Postoperative computed tomography (CT) showed a patent false lumen (FL) in the aortic arch and a reentry tear in the right subclavian artery. The remaining aortic arch enlarged, which resulted in formation of a 55-mm-diameter aneurysm. We performed reentry occlusion using embolization with glue and coil. The patient's clinical course after the procedure was uneventful, and subsequent CT showed that FL was thrombosed and had decreased in size...

During aneurysm clipping, ischemic complications may occur and require a rescue treatment, usually surgical. We present two such cases that required urgent rescue treatment, performed through an endovascular route. Our first case presented with a non-ruptured right posterior inferior cerebellar artery (PICA) aneurysm. After permanent clip positioning, occlusion of the PICA occurred. An unsuccessful attempt of clip repositioning was performed. We therefore positioned a stent obtaining complete flow restoration...

Objective: Paraclinoid aneurysms are a group of aneurysms arising at the distal internal carotid artery. Due to a high incidence of small, wide-necked aneurysms in this zone, it is often challenging to achieve complete occlusion when solely using detachable coils, thus stent placement is often required. In the present study, we aimed to investigate the effect of stent placement in endovascular treatment of paraclinoid aneurysms. Methods: Data of 98 paraclinoid aneurysms treated by endovascular approach in our center from August 2005 to June 2016 were retrospectively reviewed...

BACKGROUND AND IMPORTANCE: Fusiform intracranial aneurysms remain challenging lesions to treat. These aneurysms have historically required bypass procedures or clip remodeling constructs for cure. Recently, endovascular specialists have reported experience with flow diversion for complex fusiform aneurysms of the vertebrobasilar system, with mixed results. Vascular anatomy for anterior circulation fusiform aneurysms may make these lesions more amenable to flow diversion and embolization procedures; however, published experience with these techniques is lacking...

Congenital renal artery aneurysm is uncommon. Moreover, renal artery aneurysm concomitant with a congenital renal arteriovenous fistula is extremely rare. Transarterial embolization is the first-line treatment for these conditions. We report a case of a patient with congenital renal artery aneurysm concomitant with a congenital renal arteriovenous fistula of the upper polar left renal artery which was successfully treated by transarterial embolization with coil, glue, and Amplatzer vascular plug.

In this report, we describe a male patient who presented with recurrent life-threatening hemoptysis due to the sequential formation of multiple pulmonary aneurysms. Both pulmonary artery coil embolization and right lower lobectomy were performed, with limited success. The patient experienced extensive bilateral femoral DVT extending into the inferior vena cava, with massive hemoptysis, fulfilling the diagnosis of Hughes-Stovin syndrome. A final diagnosis of Behçet disease was made following extensive investigation, and the patient responded well to prednisone 20 mg orally and azathioprine 100 mg orally...

OBJECTIVE Intracranial stenting and flow diversion require the use of dual antiplatelet therapy (DAPT) to prevent in-stent thrombosis. DAPT may significantly increase the risk of hemorrhagic complications in patients who require subsequent surgical interventions. In this study, the authors sought to investigate whether DAPT is a risk factor for hemorrhagic complications associated with ventriculoperitoneal (VP) shunt placement in patients with aneurysmal subarachnoid hemorrhage (aSAH). Moreover, the authors sought to compare VP shunt complication rates with respect to the shunt's location from the initial external ventricular drain (EVD) site...

Background In cases of subarachnoid hemorrhage due to aneurysm rupture, the administration of an anticoagulant or antiplatelet agent involves the risk of rebleeding from the aneurysm. There is a possibility of inducing thromboembolic events during the endovascular embolization of ruptured cerebral aneurysms. Patients and methods From April 2006 to March 2017, we treated a total of 70 patients with ruptured cerebral aneurysms with an endovascular technique. Among them, five patients (7.1%) showed intra-arterial thrombus formation...

BACKGROUND: Endovascular coil embolization is an accepted treatment option for intracranial aneurysms. However, the coiling of aneurysms with an incorporated artery (IA) poses a high risk of IA occlusion. Here we report our experience of endovascular coil placement using a technique that avoids IA occlusion in aneurysms with IAs. METHODS: Over a 6-year period, 185 patients harboring 206 intracranial aneurysms underwent endosaccular coiling. Forty-two of these patients with 45 aneurysms were treated by coil placement to avoid IAs occlusion...

BACKGROUND: Posterior cerebral artery aneurysms are uncommon, with an occurrence rate of less than 1% of intracranial aneurysms. They have various shapes, including saccular and fusiform. Dissecting aneurysms may occur in distal posterior cerebral artery and they may affect the whole artery. Endovascular therapy is considered as a safe method of treatment and there are different techniques for endovascular therapy. SUMMARY: Posterior cerebral artery aneurysms are uncommon...

Low-profile stents seem to be associated with a higher incidence of thromboembolic events compared with preexisting stents. We conducted a systematic review of 11 eligible reports and a meta-analysis of 7 reports with respect to the clinical efficacy and safety of low-profile stents. There were 217 intracranial aneurysms reported; 22% were ruptured aneurysms. In all, 72% were treated using single stenting, 19% were treated using overlapping stenting, and 6% were treated using balloon angioplasty followed by stenting; 3% were used to assess the flow diverter effect in a dissecting aneurysm or were treated using unexpected subtotal coil packing...

Background: Postsurgical clipping aneurysm recurrences or residuals can be difficult to manage with either traditional open microsurgical approaches or endosaccular coiling. Endoluminal parent vessel reconstruction with flow diversion may be an ideal method for treating these recurrences by avoiding reoperative surgery or intraprocedural aneurysm rupture with aneurysm access. Method: We retrospectively reviewed a single-center aneurysm database identifying all anterior communicating artery (ACom) region aneurysms with recurrences after microsurgical clipping...

Introduction: The pipeline embolization device (PED) is increasingly used in the endovascular management of cerebral aneurysms. Longitudinal data regarding safety and benefit of the PED in anterior communicating (ACOM) artery aneurysms are limited and particularly lacking in residual ACOM artery aneurysms. We report the use of the PED in 3 patients with ACOM artery aneurysms who were previously coiled. Methods: Three patients with ACOM artery aneurysms, all previously treated with coiling and with recurrence of the aneurysm neck, were treated with the PED...
