BACKGROUND: Subarachnoid hemorrhage cases with multiple cerebral aneurysms frequently demonstrate a hemorrhage pattern that does not definitively delineate the source aneurysm. In these cases, rupture site is ascertained from angiographic features of the aneurysm such as size, morphology, and location. OBJECTIVE: To examine the frequency with which such features lead to misidentification of the ruptured aneurysm. METHODS: : Records of patients who underwent surgical clipping of a ruptured aneurysm at our institution between 2004 and 2014 and had multiple aneurysms were retrospectively reviewed...

Ventricular outpouching is a rare finding in prenatal sonography and the main differential diagnoses are diverticulum, aneurysm, and pseudoaneurysm in addition to congenital cysts and clefts. The various modes of fetal presentation of congenital ventricular outpouching include an abnormal four-chamber view on fetal two-dimensional echocardiogram, fetal arrhythmia, fetal hydrops, and pericardial effusion. Left ventricular aneurysm (LVA)/nonapical diverticula are usually isolated defects. Apical diverticula are always associated with midline thoracoabdominal defects (epigastric pulsating diverticulum or large omphalocele) and other structural malformations of the heart...

BACKGROUND: Although a rerupture after surgical clipping of ruptured intracranial aneurysms is rare, it is associated with high morbidity and mortality. The causes for retreatment and rupture after surgical clipping are not clearly defined. METHODS: From a prospectively maintained database of 244 patients who had undergone surgical clipping of ruptured intracranial aneurysms, we selected patients who experienced retreatment or rerupture within 30 days after surgical clipping...

We present two cases of Amplatzer® device deployment that exhibited long-term failure necessitating surgical correction. The first case illustrates recanalization of a ruptured Valsalva aneurysm with worsening aortic insufficiency after percutaneous repair with the Amplatzer Vascular Plugs and Amplatzer duct occluder, while the second case illustrates recanalization after deployment of the Amplatzer septal occluder in a patient with a pseudoaneursym in a bovine aorta after type I aortic dissection repair. These two cases illustrate the potential long-term complications and limitations in durability with these devices...

BACKGROUND: Multiple cerebral aneurysms are encountered in approximately 15% to 35% of patients harboring unruptured cerebral aneurysms. It would be of clinical value to determine which of them is most likely to rupture. OBJECTIVE: To characterize features of the ruptured aneurysm relative to other concomitant fellow aneurysms in patients with multiple cerebral aneurysms. METHODS: From a total of 5720 patients who were prospectively registered in the Unruptured Cerebral Aneurysm Study in Japan, a subgroup of patients with multiple cerebral aneurysms who developed subarachnoid hemorrhage was extracted for this post hoc analysis...

INTRODUCTION: Aneurysms of the carotid-ophthalmic segment are relatively rare, comprising only five percent of all intracranial aneurysms. There is no consensus regarding the optimal management for ruptured carotid-ophthalmic aneurysms, whether endovascular coiling or surgical clipping provide the most favourable patient outcome. The aim of this meta-analysis is to analyse these two treatment modalities for ruptured carotid-ophthalmic aneurysms with respect to independent clinical outcome...

Although endovascular aneurysm repair (EVAR) in the abdominal aorta has reduced the perioperative mortality when compared with open repair, the need for reintervention after complications such as endoleak may be presented in up to 20% of the cases. Type II endoleak from branch vessels is often benign but can potentially be associated with progressive abdominal aortic aneurysm growth and sac expansion. We present a rare case of a patient who presented with sac expansion and psoas hematoma due to Type II endoleak from "unusual" collaterals of IMA and was treated successfully with endoleak microembolization and percutaneous decompression of the hematoma...

Dural arteriovenous fistula(dAVF)is relatively rare, and its etiology remains uncertain. Generally, dAVF is thought to be acquired and has been reported to develop secondary to sinus thrombosis, head injury, infection, and surgery. We report a rare case of dAVF in the anterior cranial fossa that developed remote from the craniotomy site after surgery. A 52-year-old man underwent surgery for hypertensive intracerebral hemorrhage 4 years prior. Perioperative imaging modalities demonstrated no abnormal vascular malformation except for an un-ruptured anterior communicating artery aneurysm...
