OBJECTIVE The Agency of Healthcare Research and Quality (AHRQ) has defined Patient Safety Indicators (PSIs) for assessments in quality of inpatient care. The hypothesis of this study is that, in the treatment of unruptured cerebral aneurysms (UCAs), PSI events are less likely to occur in hospitals meeting the volume thresholds defined by The Joint Commission for Comprehensive Stroke Center (CSC) certification. METHODS Using the 2002-2011 National (Nationwide) Inpatient Sample, patients treated electively for a nonruptured cerebral aneurysm were selected...

Segmental arterial mediolysis is a rare vascular disease that leads to spontaneous intra-abdominal haemorrhage, which causes shock and bowel ischaemia, and is associated with a high mortality rate. Here, we present a case of spontaneous intra-abdominal haemorrhage due to segmental arterial mediolysis in a patient who underwent oesophagocolojejunostomy for synchronous triple primary cancer, which was treated successfully by coil embolization. We conclude that a preoperative angiogram is necessary to detect vascular abnormalities, and in cases with severe haemorrhage, an urgent endovascular procedure is the treatment of choice...

Although Terson's syndrome is a well-known cause of vision loss due to intracerebral aneurysm rupture, optic nerve neuropathy can also occur because of other causes. Here, we report such a case, i.e., a ruptured anterior communicating artery aneurysm accompanied by vision loss and visual field disturbances due to a cause other than Terson's syndrome. A 47-year-old man presented with right superior altitudinal hemianopia. Computed tomography (CT) showed subarachnoid hemorrhage (SAH), and three-dimensional CT angiography revealed an anterior communicating artery aneurysm...

BACKGROUND: Rupture of a persistent trigeminal artery associated with development of a cavernous sinus fistula in a traumatic setting is rare. They are typically treated with coil embolization of the cavernous sinus. CASE DESCRIPTION: We present the case of a 42-year-old woman who developed a direct cavernous carotid fistula after a motor-vehicle accident. Angiographic imaging revealed a rupture point of a persistent trigeminal artery as it connected with the cavernous segment of the internal carotid artery (ICA), causing a cavernous sinus fistula...

A 74-year-old man with hoarseness was diagnosed with a right-sided aortic arch and Kommerell's diverticulum by computed tomography (CT). The diverticulum had a maximum diameter of 33 mm, and surgical intervention was chosen because of the possibility of rupture. A right common carotid to right subclavian artery bypass was constructed, stent-graft was placed after the branching of the right common carotid artery, and coil embolization of the diverticulum was performed via left brachial artery. No leaks were found on postoperative CT...

A 78-year-old woman was admitted with benign biliary stenosis. A plastic stent was placed at the left branch to prevent obstructive cholangitis. Two weeks after the procedure, the patient was readmitted with cholangitis caused by hemobilia. However, computed tomography (CT), endoscopic retrograde cholangiopancreatography (ERCP), peroral cholangioscopy, and abdominal angiography failed to establish the bleeding source. At the seventh bleeding, CT revealed a hepatic artery pseudoaneurysm for which coil embolization was successfully performed...

A man aged 61 years with a history of a ruptured basilar fenestration aneurysm underwent unassisted coiling in 1997 and repeat intervention for a recurrence at the aneurysm mouth in 2011. At repeat intervention, the decision was made to intentionally leave some filling at the base to preserve the parent vessels. Stent-assisted coil embolization, although technically feasible, was not pursued given the relative risks of the procedure. In 2017, the patient returned for repeat surveillance and further coil compaction was found at the aneurysm base...

Endoscopic third ventriculostomy (ETV) is a common treatment for noncommunicating hydrocephalus. Although rare, vascular injury and traumatic pseudoaneurysm development during ETV have been reported. The authors present the case of a 13-year-old boy who underwent repeat ETV (rETV) for shunt and ETV failure, and who suffered an intraoperative subarachnoid hemorrhage due to iatrogenic injury to the basilar tip, with subsequent development of a pseudoaneurysm. Despite initial primary coil embolization, the aneurysm recurred and was definitively treated with flow diversion...

BACKGROUND: Bronchopulmonary sequestration is a congenital abnormality of the primitive foregut. In adults, the typical age at presentation is 20-25 years. CASE REPORT: A 64-year-old female was referred for evaluation of an 8 × 6-cm right lower lobe cystic lesion. Her medical history was significant for recurrent right lower lobe pneumonia requiring multiple hospitalizations. Her physical examination was significant for crackles at the right lung base. Computed tomography (CT) of the chest with contrast showed cystic changes with thickened septation of the medial segment of the right lower lobe lacking distinct visceral pleura and with arterial supply from the anomalous branch of the thoracic aorta arising near the celiac trunk...

The authors present a case of a 39-year-old man with alcoholic chronic pancreatitis that was admitted in the emergency department after a car accident, complaining of abdominal pain and looking pale. The patient was hemodinamically unstable, requiring blood transfusions. He underwent computed tomography angiogram of the abdomen and pelvis, showing a pseudoaneurysm of the gastroduodenal artery and a hemoperitoneum. He was referred to our interventional radiology unit and submitted to endovascular treatment, consisting of 'backdoor' and 'frontdoor' embolization of the gastroduodenal artery and pseudoaneurysm neck with coils, with total exclusion in control angiography...

Isolated pulmonary arteriovenous malformations (PAVM) are rare, but can be responsible for paradoxical embolic events. It is important to recognise these situations early and intervene quickly to attain the best outcome. We describe the case of a 45-year-old woman with a long-standing history of migraines with aura who presented to the emergency department with left-sided weakness and slurred speech. Work-up was unclear and she was diagnosed with cryptogenic stroke. Follow-up transoesophageal echocardiogram was suggestive of an atrial septal defect, though no clear defect was evident...

Coronary artery aneurysms (CAA) represent an uncommon disease with yet unclear standards of treatment. Clinical and anatomic characteristics determine choice of treatment. Stent-assisted coil embolization has been described as a valuable option for management of patients with wide-neck coronary aneurysms. Choice of appropriate stent sizing can be challenging particularly when there is a large difference between proximal and distal diameters. We report a case of stent-assisted coil embolization of a coronary aneurysm using a self-expandable stent...

Systemic to pulmonary arterial collaterals (SPC) are commonly found in patients undergoing staged operative palliation for single ventricle heart disease. Occlusion of SPC as part of pre-Fontan catheterization has been shown to improve hemodynamics acutely. Anecdotally, the effect of this intervention appears to be transient, and to our knowledge there is no data supporting its durability in these patients. Between 1/1/2016 and 5/1/2017, 24 children underwent Glenn operations at our institution. Of these, 3 patients had signs and symptoms deteriorating clinical status suggestive of volume overload in the period between their Glenn operation and Fontan completion, prompting heart catheterization...

Late ocular manifestations of aneurysmal subarachnoid hemorrhage (SAH) have not been previously investigated except for one study which demonstrated that one half of patients subjected to aneurysm clipping suffer from symptoms of visual pathway impairment. We assessed ophthalmological status of patients after 1-4.5 years from SAH and aneurysm embolization to identify predictors of damage to the visual pathways. Complete ophthalmological examination, static perimetry, and visual evoked potentials (VEPs) were performed in 74 patients (26 men, 48 women, aged 19-76 years), who constituted a consecutive sample of 129 patients treated with aneurysm embolization in the years 2008-2010...

BACKGROUND: Pediatric intracranial aneurysms (IAs) are rare. Compared to adult IAs, they are more commonly giant, fusiform, or dissecting. Their treatment often proves more complex and recurrence rate and de novo aneurysmogenesis incidence is higher. A consensus regarding the most appropriate algorithm for following pediatric IAs is lacking. METHODS: We thus sought to generate recommendations based on the reported experience in the literature with pediatric IAs, through a thorough review of the Pubmed database, discussion with experienced neurointerventionalists, and our own experience...

CASE DESCRIPTION A 17-month-old neutered female Labrador Retriever with a 3- to 4-month history of abdominal distention was referred for evaluation and treatment. CLINICAL FINDINGS Evaluation of a peritoneal fluid specimen collected by the referring veterinarian indicated a pure transudate. At admission, transabdominal ultrasonography revealed microhepatica, dilation of the intrahepatic and mesenteric vasculature, peritoneal effusion, and multiple aberrant blood vessels. A large, high-flow hepatic arteriovenous malformation (HAVM) with secondary portal hypertension, peritoneal effusion, multiple acquired portosystemic shunts, and microhepatica was evident on CT angiography...

BACKGROUND: Stent assisted coil embolization (SACE) of bifurcation aneurysms is challenging. Heterogeneous results have been achieved to date, but largely for laser cut stents. While braided stents offer multiple technical advantages, their long term efficacy has yet to be validated. OBJECTIVE: To report the first long term 18 month results for the durability of bifurcation aneurysms treated with braided stents. MATERIALS AND METHODS: Over a 4 year period, 59 consecutive patients with 60 bifurcation aneurysms underwent elective braided SACE across three Australian neurovascular centers...
