The authors report on an 81-year-old woman with a pathologic hangman's fracture secondary to a complex arteriovenous fistula (AVF). The patient presented with severe, unremitting neck pain and was found to have fractures bilaterally through the pars interarticularis of C-2 with significant anterior subluxation of C-2 over C-3 along with widening of the left transverse foramen. Due to an abnormally appearing left vertebral artery (VA) on CT angiography, the patient underwent conventional angiography, which revealed a complex AVF stemming from the left VA at the level of C-2 with dilated posterior cervical veins and a large venous varix...

We report a coil embolization -assisted thoracic endovascular aortic repair technique successfully applied to multiple saccular descending aortic aneurysms in a 74-year-old man. Due to the most distal aneurysm being located at the celiac trunk level and the distance between the superior mesenteric artery and the aneurysm being only 10mm, a coil embolization of the distal saccular aneurysm was performed prior to stent delivery to secure a sufficient landing zone. Postoperative computed tomography showed an appropriate positioning of the endovascular devices without endoleak...

Posterior cerebral artery (PCA) aneurysms are rare, and direct surgery of these is considered difficult. Coil embolization of PCA aneurysms is becoming popular. However, it is difficult to completely obliterate the aneurysm while preserving the flow of the parent artery in large or giant PCA aneurysms with a wide neck with this technique. We report a case of a large and wide-necked PCA aneurysm with multiple recurrences following successful surgical clipping and coil embolization.A 77-year-old man with a large unruptured right PCA (P2) aneurysm was successfully treated by surgical clipping...

Pseudoaneurysm is a rare complication of ankle sprain, with 18 case reports published in the current literature. In the vast majority of the cases, they were treated surgically. We present three cases of pseudoaneurysm following ankle sprain, treated by non-surgical methods in two cases, and spontaneously healed in another. The diagnosis was made between two and four weeks after the traumatism, by ultrasonography and arteriography in two cases, and only by ultrasonography in a third case. The pseudoaneurysms originated respectively from the perforating fibular artery, the dorsal pedis artery, and a lateral malleolar artery...

A 24-year-old male presented with classic features of the nephrotic syndrome. An initial renal biopsy revealed minimal change disease and thereafter, a second biopsy showed features of focal and segmental glomerulosclerosis. There was no response to conventional immunosuppression, and the patient had to be given rituximab; in spite of this, he went on to develop end-stage renal disease. He continued to have heavy proteinuria leading to severe hypoalbuminemia, thrombosis, infections, and malnutrition, placing the patient in a life-threatening situation...

In the present report, we describe a case of a patient with an asymptomatic aneurysm in the arc of Bühler (AOB), which was successfully treated by transcatheter arterial embolization. The patient presented with severe stenosis of the celiac trunk, which was suspected to be due to median arcuate ligament syndrome. Arteriography of the superior mesenteric artery indicated a rapid stream in an aneurysm in the AOB. Hence, embolization was carefully performed using detachable coils and microcoils. An arteriography performed after embolization did not show any aneurysm, and the hepatic artery and splenic artery could be detected via the pancreatic arcade, originating from the superior mesenteric artery...

Cardiac catheterization is commonly performed in patients being supported by extracorporeal membrane oxygenation (ECMO). We aimed to evaluate the safety, benefit, and outcomes of catheterization in pediatric patients supported by ECMO. Retrospective review of cardiac catheterizations performed in patients ≤18 years of age while on ECMO at a large tertiary care center between January 2000 and May 2015. A total of 55 catheterizations were performed on 51 patients during 53 unique ECMO courses. Indications for ECMO include ventricular dysfunction (22), cardiac arrest (20), inability to wean from cardiopulmonary bypass (7), and persistent cyanosis (4)...

Aneurysms of the anterior cerebral artery (ACA) located distal to the anterior communicating artery complex (ACOM) remain challenging to treat with surgical clip reconstruction as well as with endovascular coil-embolization strategies. We have treated five complex geometry distal ACA aneurysms with endoluminal reconstruction using the Pipeline Embolization Device (PED). Two aneurysms were of the dysplastic fusiform type. Three aneurysms were of complex saccular configuration. Three aneurysms were treated electively at the outset with PED...

Subintimal angioplasty of lower limb arterial occlusion carries a relatively higher risk of vessel perforation compared to transluminal angioplasty. Vessel perforation is a potentially life threatening complication which requires prompt recognition and management. They are usually managed by endovascular techniques such as low-pressure balloon tamponade, covered stents, and coil embolization of the ruptured artery. We describe a technique of treating vessel perforation following balloon angioplasty. Patient developed a large perforation of the proximal superficial femoral artery (SFA) after balloon inflation during subintimal angioplasty of complete SFA occlusion...

Improved endovascular embolization of vascular conditions can generate better patient outcomes and minimize the need for repeat procedures. However, many embolic materials, such as metallic coils or liquid embolic agents, are associated with limitations and complications such as breakthrough bleeding, coil migration, coil compaction, recanalization, adhesion of the catheter to the embolic agent, or toxicity. Here, we engineered a shear-thinning biomaterial (STB), a nanocomposite hydrogel containing gelatin and silicate nanoplatelets, to function as an embolic agent for endovascular embolization procedures...
