We report a case of tentorial dural arteriovenous fistula (DAVF) with a severe intracranial hemorrhage occurring after Onyx embolization. A 40-year-old man presented with an asymptomatic tentorial DAVF on angiography. Transarterial embolization with Onyx was performed via the middle meningeal artery, and the cast filled the fistula itself and its proximal draining vein. Postoperative angiography confirmed complete occlusion of the DAVF. A computed tomography scan performed immediately after the procedure demonstrated an acute subdural hematoma with the temporal hemorrhage...

Background Ureteral arterial fistulas are rare but potentially life threatening. We present a female who developed a ureteral arterial fistula following a right robotic nephrectomy. After several endovascular interventions to control the bleeding had failed, we approached the fistula through the right ureteral stump with coil embolization. Methods Coil embolization of the right ureteral stump was performed. We utilized a 6Fr × 45 cm sheath inserted through one of the cystoscope channels to cannulate the right ureteral orifice...

BACKGROUND AND PURPOSE: Chronic hypoperfusion from athero-stenotic lesions is thought to lead to better collateral recruitment compared to cardioembolic strokes. It was sought to compare collateral flow in stroke patients with atrial fibrillation (AF) versus stroke patients with cervical atherosclerotic steno-occlusive disease (CASOD). METHOD: This was a retrospective review of a prospectively collected endovascular database. Patients with (i) anterior circulation large vessel occlusion stroke, (ii) pre-treatment computed tomography angiography (CTA) and (iii) intracranial embolism from AF or CASOD were included...

BACKGROUND: This study was aimed to determine risk factors for the recurrence of an intracranial saccular aneurysm (ISA) following endovascular treatment. The findings will help medical professionals to identify patients having a high risk of ISA recurrence and assist them in developing appropriate follow-up plans. RESULTS: During the follow-up period, 12.6% of the patients (83/658) experienced recurrent ISAs. An analysis of related factors, including gender, age, hypertension, diabetes mellitus, smoking, tumor size, width of the aneurysm neck, the presence or absence of a rupture, the volume embolization ratio (VER), the application or nonapplication of a stent, and follow-up time, revealed that a tumor size > 10 mm in diameter, wide-necked aneurysms, an anterior communicating or middle cerebral artery aneurysm, an aneurysm rupture, a VER < 20%, the absence of stent assistance, and follow-up time were high-risk factors for the recurrence of ISAs...

Spinal cord ischemia(SCI) has been devastating complication of endovascular thoracic and thoracoabdominal aortic repair. Spinal cord blood supply arises from not only segmental artery, subclavian artery, hypogastric artery and these branches, but also perivertebral vasculature and paravertebral muscle and small arterial network, and risk factors of SCI were multifactorial. There are several adjuncts/strategies which are utilized to minimize the incidence of SCI: cerebrospinal fluid drainage, perioperative management of high mean arterial pressure, intraoperative evoked potential monitoring, and staged thoracoabdominal aortic repair...

Background and importance Intraorbital arteriovenous fistulas (IOAVFs) are rare and cause eye redness, exophthalmos, blurry vision and bruit. Whereas in the past they were treated conservatively, surgically or transarterially, recent developments in transvenous embolization have improved their treatment. In this paper the authors report three cases of IOAVFs treated endovascularly and review the evolution of treatment options. Methods Three cases of purely IOAVF enrolled in our center were reported and a PubMed literature search was performed using "pure intraorbital arteriovenous fistula" and "arteriovenous fistula of the optic nerve sheath...

OBJECTIVE Small acute epidural hematomas (EDHs) treated conservatively carry a nonmeasurable risk of late enlargement due to middle meningeal artery (MMA) lesions. Patients with EDHs need to stay hospitalized for several days, with neurological supervision and repeated CT scans. In this study, the authors analyzed the safety and efficacy of the embolization of the involved MMA and associated lesions. METHODS The study group consisted of 80 consecutive patients harboring small- to medium-sized EDHs treated by MMA embolization between January 2010 and December 2014...

Tissue plasminogen activator (tPA) is currently used in combination with endovascular procedures to enhance recanalization and cerebral reperfusion and is also currently administered as standard-of-care thrombolytic therapy to patients within 3-4.5 h of an ischemic stroke. Since tPA is not neuroprotective or cytoprotective, adjuvant therapy with a neuroprotective or an optimized cytoprotective compound is required to provide the best care to stroke victims to maximally promote clinical recovery. In this article, we describe the use of a sensitive standardized protease assay with CH3SO2-D-hexahydrotyrosine-Gly-Arg-p-nitroanilide•AcOH, a chromogenic protease substrate that is cleaved to 4-nitroaniline (p-nitroaniline) and measured spectrophotometrically at 405 nm (OD405 nm), and how the assay can be used as an effective screening assay to study drug-tPA interactions...

Isolated internal iliac artery aneurysms (IIIAAs) are extremely rare. We present the case of a 75-year-old white Caucasian male patient admitted for right lower limb deep venous thrombosis and low-risk pulmonary embolism due to the compression of the external iliac vein from an IIIAA. A review of the literature was also performed to identify the epidemiologic, clinical characteristics and diagnostic and operative strategies of this disease. At present, a recommendation for the best operative strategy in the presence of an IIIAA is difficult...

Congenital vascular malformation (CVM) between the external carotid artery and the internal jugular vein is a rare disease, it originates as a consequence of arrested development during various stages of embryogenesis. The natural history of CMVs is progressive growth, it can remain clinically silent until it progresses causing local swelling accompanied by symptoms and signs of arteriovenous shunting, mass effect, ischemic insult with ulceration of skin or bleeding. In literature only few cases of CMVs have been reported, therefore there is still no consensus about the correct surgical approach to this pathology...

Ultrasound-assisted catheter-directed thrombolysis therapy has emerged more recently as a management strategy for patients with intermediate risk pulmonary embolism and has shown promising results in clinical trials by early reversal of right ventricle dilation, reduced pulmonary hypertension, and decreased anatomic thrombus burden. This therapeutic strategy requires a small fraction of the systemic fibrinolytic dose and is therefore associated with a reduced bleeding risk. Although intracranial hemorrhage has not been reported in clinical trials, it is a possible complication...

True visceral artery aneurysms (VAAs) are a rare entity with an incidence of 0.01-2%. The risk of rupture varies amongst the different types of VAAs and is higher for pseudo aneurysms compared with true aneurysms. Size, growth, symptoms, underlying disease, pregnancy and liver transplantation have all been associated with increased risk of rupture. Mortality rates after rupture are around 25%. The splenic artery is most commonly affected and the etiology is predominantly atherosclerosis. Open repair can be done by simple ligation or reconstruction of the artery, while endovascular options include embolization or using a stent graft...

The modern treatment of acute mesenteric ischemia (AMI) requires seamless collaboration of gastrointestinal surgeons, vascular surgeons, and interventional radiologists. The treatment strategy is straightforward aiming at rapid restoration of blood flow to the intestine. Bowel resection is performed on demand. The first thing to consider is the patient's clinical condition at presentation, whether there are signs of peritonitis or not, and whether the patient is hemodynamically stable or not. Second, there are four etiologies of AMI that need to be distinguished as they differ in treatment: superior mesenteric artery embolism, mesenteric arterial occlusive disease, mesenteric venous thrombosis, and non-occlusive mesenteric ischemia...
