PURPOSE: To report hepatic arterial-related complications encountered during planning and treatment angiograms for radioembolization and understand any potential-associated risk factors. MATERIALS AND METHODS: 518 mapping or treatment angiograms for 180 patients with primary or metastatic disease to the liver treated by Yttrium-90 radioembolization between 2/2010 and 12/2015 were retrospectively reviewed. Intra-procedural complications were recorded per SIR guidelines...

PURPOSE: Long-term occlusion of coiled aneurysms frequently fails, probably because of poor intrasaccular healing and inadequate endothelialization across the aneurysm neck. The purpose of this study was to determine if attachment of autologous mesenchymal stem cells (MSCs) to platinum coils would improve the healing response in an elastase-induced aneurysm model in rabbits. MATERIALS AND METHODS: With approval from the institutional animal care and use committee, aneurysms were created in rabbits and embolized with control platinum coils (Axium; Medtronic) (n=6) or coils seeded ex vivo with autologous adipose-tissue MSCs (n=7)...

A 6-month-old intact male Standard Dachshund was referred for evaluation of a soft tissue swelling above the right eye. Examination of the right eye revealed mild lateral deviation of the globe, normal vision, and a dorsonasal soft tissue swelling. Examination of the posterior segment was normal. Dual-phase computed tomography angiography was consistent with an orbital varix of the angularis oculi and right dorsal external ophthalmic veins with no evidence of arterial involvement. Treatment involved fluoroscopically guided coil embolization of the venous outflow with nine platinum microcoils, followed by sclerotherapy of the varix using 1...

BACKGROUND: The present study is an evaluation of the efficacy of endovascular treatment in emergency setting for patients with acute peripheral and visceral arterial injury secondary to penetrating or blunt trauma. METHODS: Twelve patients (11 men) aged 35.8±11.3 years (range: 18-56 years) with penetrating or blunt trauma who underwent endovascular treatment in our department between March 2010 and June 2014 for peripheral and visceral arterial injury were retrospectively reviewed...

PURPOSE: The objective of this study was to evaluate the effect of substituting 50% Isovue (Bracco Diagnostics Inc, Monroe Township, NJ) for sterile water on the delivery of Y resin microspheres (SIR-Spheres [Sirtex Medical Limited, Sydney, Australia]). MATERIALS AND METHODS: The authors retrospectively reviewed all SIR-Spheres radioembolizations at the authors' institution from January 1, 2011, to February 10, 2014. From January 1, 2011, to April 30, 2013, all users performed SIR-Spheres radioembolization per the manufacturer's original instructions using sterile water in the B and D lines and intermittently checking the progress of the embolization by injecting contrast via the B line...

Hepatic aneurysms are rare, but can prove fatal once they rupture. Transcatheter arterial embolization (TAE) is performed as a prophylactic treatment. The position of the aneurysm determines the degree of difficulty of TAE. Maintaining blood flow to the liver can become difficult, particularly when the aneurysm is at an arterial junction. The patient was a 72-year-old man diagnosed with a hepatic aneurysm. The aneurysm was situated on the common hepatic artery at the junction of the gastroduodenal and proper hepatic arteries...

INTRODUCTION: Traumatic intracranial aneurysms in children are rare and may occur as the result of closed or penetrating head trauma. Their natural history seems to be more aggressive. Most traumatic aneurysms have complex shape, tending to have a large neck or even a fusiform morphology. CASE REPORT: We present a case of a traumatic carotid artery aneurysm in a 9-year-old girl that was successfully treated with pipeline embolization device. DISCUSSION: Due to its dissecting nature, wall friability and lack of a substantial neck can make surgical clipping and selective coiling difficult and risky...

BACKGROUND: Foreign body emboli during endovascular treatment (EVT) may cause delayed enhancing lesions (DELs). OBJECTIVE: To report our experiences of this complication in patients treated for cerebral aneurysms and to investigate the cause of the lesions by benchtop analyses. METHODS: Three patients with DELs on MRI after EVT were retrospectively investigated. Unusual friction had occurred in the midst of coil delivery in two patients. The imaging findings, cause of the lesions due to the devices used for the procedure, treatment, and follow-up results were assessed...

Background Intracranial pseudoaneurysm formation due to a ruptured non-traumatic aneurysm is extremely rare. We describe the radiological findings and management of pseudoaneurysms due to ruptured cerebral aneurysms in our case series and previously reported cases. Patients and methods Four additional and 20 reported patients presenting with subarachnoid hemorrhage (SAH) are included. Radiological findings and clinical features of these patients were reviewed. Results In our series, three-dimensional computed tomographic angiography (3D-CTA) and/or angiography showed an irregular- or snowman-shaped cavity extending from the parent artery...

An 85-year-old man complained of a 2-month history of pain on the left side of his face. Brain computed tomography (CT) and magnetic resonance imaging/magnetic resonance angiography did not clearly show any intracranial abnormality and only showed fluid effusion in his left sphenoid sinus. Filamentous fungi were detected from the left sphenoid sinus specimen. The isolate was Scedosporium apiospermum. He was empirically treated with voriconazole, to which the isolate was susceptible. His consciousness decreased rapidly...

Haemobilia is a rare cause of upper gastrointestinal bleeding that consists of haemorrhage within the biliary tree. Most cases of haemobilia are due to iatrogenic cause, laparoscopic or open cholecystectomy, abdominal trauma, gallstones, hepatic tumours, vascular aneurism. We present the case of a male patient admitted in the surgery department for epigastric and right hypochondria pain, nausea and vomiting. Open cholecystectomy was performed with a trans-cystic tube drainage. Postoperative outcome was favourable but with a continuous decrease in haemoglobin level...

PURPOSE: Intracranial aneurysms with an acutely angled parent vessel are difficult to enter using conventional techniques. This study examined the efficacy, safety, and technical aspects of the intraluminal, intra-aneurysmal, and in vitro microcatheter looping techniques. MATERIALS AND METHODS: Twenty-nine consecutive patients harboring intracranial aneurysms with an incorporated acute angle branch were treated with a microcatheter looping technique (MLT) after having failed treatment with conventional techniques...

This report aims to present an unusual case with isolated bilaterally located internal iliac artery aneurysms (IIAAs) that were incidentally detected. Owing to the high surgical risk of the patient and anatomical location of the aneurysms, an endovascular management was preferred. Initially, the patient underwent a percutaneous embolization of the right-sided aneurysm with coiling. A stent-graft deployment covering the orifice of the left-sided internal iliac artery and occluding the ipsilateral aneurysm followed 1 month later...

Objective In cerebral aneurysm clipping and embolization, blood pressure control and temporary parent artery blocking are common methods to prevent aneurysm rupture. Their influence on the prognosis is uncertain. In this study, we try to find out the association between methods above and prognostic indicators.Methods We held a retrospective analysis on patients' medical records of cerebral aneurysms surgical clipping and endovascular coiling , and recorded gender, age, diagnosis, Hunt-Hess grade, Glasgow coma scale score, treatment methods, a history of hypertension, preoperative systolic blood pressure, with or without controlled hypotension, systolic blood pressure difference before and after controlled hypotension, with or without temporary artery blocking, with or without hypertension after treated aneurysm, prognostic indicators including mortality after 1 month, intensive care unit (ICU) stay time of survivors, discharged Glasgow outcome scale (GOS) score...

BACKGROUND: Cervical hematomas can lead to airway compromise, a life threatening condition, regardless of the cause. The following case is the first presentation of cervical hematoma as a complication of endovascular treatment of middle cerebral artery aneurysm. CASE REPORT: A 49 year-old woman was scheduled for stent placement under general anesthesia for middle cerebral artery aneurysm. Few days before intervention, acetyl salicylic acid and clopidogrel treatment was started...
