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...

Endovascular repair of dissecting thoracoabdominal aneurysms (TAAA) is challenging and often requires multiple procedures. A 61-year-old man with a dissecting type-II TAAA treated first by placement of a thoracic endograft, and subsequently implantation of a fenestrated endograft. Six months postoperatively, a 10mm increase of the aorta was observed. A re-entry tear in left external iliac artery(EIA) was perfusing the false lumen in a retrograde fashion connecting with the endoleak caused by the inferior mesenteric artery and lumbar arteries...

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...

Chimney endovascular aneurysm repair provides an endovascular treatment for complex aortic aneurysms. However, type I gutter endoleaks can complicate this approach and prevent full aneurysm exclusion. Treatment of these leaks can be challenging. We report successful embolization of a type I gutter endoleak after (chimney endovascular aneurysm repair) via a transcaval approach.

This report describes perioperative hemodynamic monitoring of the common hepatic artery (CHA) during endovascular treatment of a pancreaticoduodenal arcade aneurysm, in a patient with celiac artery stenosis caused by the median arcuate ligament. Pressure monitoring was performed as a safety measure against critical complications such as liver ischemia. As the aneurysm was located in the anterior pancreaticoduodenal artery (APDA) and the posterior pancreaticoduodenal artery (PPDA) was small in caliber, the patient was considered to be at a high risk of liver ischemia...

PURPOSE: To compare results of simple coverage vs preemptive embolization to exclude the internal iliac artery (IIA) during endovascular repair of aortoiliac aneurysms. METHODS: A systematic review of the literature was conducted by searching MEDLINE, CENTRAL, and OpenGray databases until March 2016. Primary outcome measures were safety and efficacy of the 2 strategies. Safety was determined by 30-day mortality and the minor and major complication rates. Efficacy was determined by absence of endoleak from the target IIA...

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...

BACKGROUND: Hereditary hemorrhagic telangiectasia (HHT) is characterized by mucocutaneous telangiectasia and visceral vascular malformations (VMs). Liver involvement with VMs may lead to high-output cardiac failure, portal hypertension, and biliary disease. There is no curative treatment for the disease, and liver transplantation is indicated for life-threatening complications. Herein, we report a case of multiple hepatic artery aneurysms (HAAs) in a patient with HHT in which open arterial reconstruction was performed...

Type II endoleaks occur commonly following endovascular aneurysm repair (EVAR). Although they remain enigmatic, multiples studies have evaluated preoperative risk factors and strategies for prevention of type II endoleaks. Prophylactic treatment of type II endoleaks can include embolization of accessory arteries, as well as complete aneurysmal sac occlusion. Regular post-operative surveillance and screening for type II endoleaks with triple-phase CTA is the standard of care. Aneurysm size and growth rate are factors that predict whether a persistence type II endoleak is hemodynamically significant, and whether it requires treatment with percutaneous trans-lumbar or trans-arterial embolization techniques...

Renal artery aneurysms (RAAs) are rare with an estimated incidence of 0.1% in the general population, and they represent approximately 25% of all visceral aneurysms. The gold standard of treatment is open surgery, but it is associated with a high risk of nephrectomy, mortality, and morbidity. Less invasive endovascular therapies are becoming increasingly common for the treatment of RAAs. Here, we aimed to report three cases of wide-necked complex renal artery aneurysms treated endovascularly using stent-assisted coil embolization with self-expandable stent nitinol Solitaire AB and Concerto Axium coils...
