BACKGROUND: Gastroduodenalartery (GDA) pseudo-aneurysms are very rare. Their clinical importance lies in the eventuality of rupture, causing bleeding and ultimately exsanguination. CASE PRESENTATION: We report the case of a man, with prior history of biliary surgery, presenting with haemobilia secondary to a rupture of GDA pseudo-aneurysm eroding the main bile duct. The patient was treated with coil embolization. This technique is considered to be safe. However, on the long term, some complications may occur...

BACKGROUND: Approximately 17% of ruptured anterior communicating artery (ACoA) aneurysms were deemed unsuitable for coil embolization during the Barrow Ruptured Aneurysm Trial (BRAT), most commonly due to unfavorable dome-to-neck ratio or small size. OBJECTIVE: To compare patients treated by coil embolization for ruptured ACoA aneurysms during the trial to those treated after the trial to determine whether advances in endovascular techniques have allowed for effective treatment of these lesions...

Vertebral artery (VA) aneurysms in the paediatric population are a rare but a serious condition. However, the epidemiology of paediatric VA aneurysms is poorly understood and there is little consensus on what constitutes the appropriate treatment. Although multiple treatment options are available, including surgery, endovascular approaches, coil embolization and parent artery occlusion, there is limited clinical evidence regarding which approach is most optimal. This review outlines the current literature and evidence outlining the epidemiology, presentation, pathogenesis and treatment of paediatric VA aneurysms...

Blood-blister like aneurysms (BBAs) are challenging lesions because of their wide fragile neck. Flow-diverting stents (FDSs), such as the Pipeline Embolization Device (PED), have been applied to treat BBAs less amenable to more established techniques of treatment. However, the use of FDSs, including the PED, in acute subarachnoid hemorrhage (SAH) still remains controversial. We report a case of aneurysm regrowth following PED application for a ruptured BBA that overlapped the origin of the dominant posterior communicating artery (PCoA), which was successfully treated after coil trapping of the origin of the fetal-type PCoA...

In endovascular coil embolization of intracranial aneurysms, very soft coils, often called "finishing coils," are usually selected in the final stage of coil embolization. The authors developed a radiolucent coil made of thin nylon thread to evaluate the performance of coils under a situation simulating the course of embolization. The characteristics of various types of finishing coils were investigated using radiolucent coils. Experimental embolization was performed with a silicone aneurysm filled with radiolucent coils simulating the final stage of embolization...

The horizontal stenting technique facilitates endovascular treatment of wide-necked bifurcation intracranial aneurysms. Previous literature shows, however, that subsequent coil embolization at initial treatment results in incomplete obliteration in many cases. The authors present two consecutive cases of wide-necked large bifurcation aneurysms to describe an additional coil embolization technique following horizontal stenting. The patients were a 53-year-old female with an unruptured internal carotid artery terminus aneurysm and a 57-year-old female with a recurrent basilar artery tip aneurysm...

OBJECTIVE Treatment of wide-necked intracranial aneurysms is associated with higher recanalization and complication rates; however, the most commonly used methods are not specifically designed to work in bifurcation lesions. To address these issues, the authors describe the evolution in the design and use of the eCLIPs (Endovascular Clip System) device, a novel hybrid stent-like assist device with flow diverter properties that was first described in 2008. METHODS A registry was established covering 13 international centers at which patients were treated with the second-generation eCLIPs device...

OBJECTIVE Intracranial bifurcation aneurysms are complex lesions for which current therapy, including simple coiling, balloon- or stent-assisted coiling, coil retention, or intrasaccular devices, is inadequate. Thromboembolic complications due to a large burden of intraluminal metal, impedance of access to side branches, and a high recurrence rate, due largely to the unmitigated high-pressure flow into the aneurysm (water hammer effect), are among the limitations imposed by current therapy. The authors describe herein a novel device, eCLIPs, and its use in a preclinical laboratory study that suggests the device's design and functional features may overcome many of these limitations...

BACKGROUND: Mixed intracranial aneurysms are vascular lesions appearing in the ruptured saccular aneurysms whose blood is contained by perivascular tissues forming another cavity called pseudoaneurysm. All cases until now have been reported in the literature with subarachnoid hemorrhage. CASE DESCRIPTION: A 65-year-old woman presented with multiple brain aneurysms with no history of subarachnoid hemorrhage. Endovascular treatment was chosen for left-sided aneurysms [lateral carotid wall (LCW) and posterior communicating (PCom)]...

Aneurysm formation is a potential complication of granulomatosis with polyangiitis (GPA), previously known as Wegener's granulomatosis. It is a very rare complication, but immediate diagnosis and therapy should be performed because an aneurysm can be life-threatening if it ruptures. An accessory left gastric artery (ALGA) is also a rare variant gastric artery that may obtain its blood supply from the left hepatic artery and left gastric artery. We herein describe a 57-year-old Japanese man who was diagnosed with GPA complicated by aneurysm rupture in an ALGA...

OBJECTIVE The Barrow Ruptured Aneurysm Trial (BRAT) is a prospective, randomized trial in which treatment with clipping was compared to treatment with coil embolization. Patients were randomized to treatment on presentation with any nontraumatic subarachnoid hemorrhage (SAH). Because all other randomized trials comparing these 2 types of treatments have been limited to saccular aneurysms, the authors analyzed the current BRAT data for this subgroup of lesions. METHODS The primary BRAT analysis included all sources of SAH: nonaneurysmal lesions; saccular, blister, fusiform, and dissecting aneurysms; and SAHs from an aneurysm associated with either an arteriovenous malformation or a fistula...

OBJECTIVE Outcome analysis of comatose patients (Hunt and Hess Grade V) after subarachnoid hemorrhage (SAH) is still lacking. The aims of this study were to analyze the outcome of Hunt and Hess Grade V SAH and to compare outcomes in the current period with those of the pre-International Subarachnoid Aneurysm Trial (ISAT) era as well as with published data from trials of decompressive craniectomy (DC) for middle cerebral artery (MCA) infarction. METHODS The authors analyzed cases of Hunt and Hess Grade V SAH from 1980-1995 (referred to in this study as the earlier period) and 2005-2014 (current period) and compared the results for the 2 periods...

BACKGROUND AND PURPOSE: We have previously demonstrated that the local delivery of monocyte chemotactic protein-1 (MCP-1) via an MCP-1-releasing poly(lactic-co-glycolic acid)-coated coil promotes intra-aneurysmal tissue healing. In this study, we demonstrate that interleukin-6 (IL-6) and osteopontin are downstream mediators in the MCP-1-mediated aneurysm-healing pathway. METHODS: Murine carotid aneurysms were created in C57BL/6 mice. Drug-releasing coils (MCP-1, IL-6, and osteopontin) and control poly(lactic-co-glycolic acid) coils were created and then implanted into the aneurysms to evaluate their intra-aneurismal-healing capacity...

INTRODUCTION: Diminished pelvic arterial flow as a result of intentional coverage/embolization of internal iliac arteries (IIA) during isolated endovascular common iliac artery aneurysm (CIAA) repair or endovascular repair of abdominal aortic aneurysms (EVAR) may result in symptomatic pelvic ischemia. While generally well tolerated, in severe cases pelvic ischemia may manifest as recalcitrant buttock claudication, vasculogenic impotence, or perineal, vesicle, rectal, and/or spinal cord ischemia...

Large celiac artery aneurysms are associated with a high rupture and mortality risk. Traditionally, open surgical repair has been the mainstay of treatment. Endovascular alternatives have been increasingly described, ranging from coil embolization to exclusion with covered stent grafts. However, certain features such as a short wide neck, small vessel diameters, and significant vessel tortuosity can limit these two options. We describe a 75-year-old man with a splenic and celiac trunk aneurysm that was treated using a combination of coil embolization to occlude the outflow artery and aneurysm sac, and an aortic stent graft cuff to block the inflow...

Intracranial infectious aneurysm (IIA) is a rare form of cerebrovascular malformation for which obliteration may be undertaken after rupture or non-response to targeted antibiotic therapy. We discuss the case of a 19-year-old man who presented with acute neurologic decline (Glasgow Coma Scale of 8) and endocarditis. CT images demonstrated subarachnoid haemorrhage, hydrocephalus and a mycotic aneurysm on the left posterior cerebral artery. Conservative management was initially decided due to the high risk of stroke and hemianopia...

PURPOSE: Spontaneous dissection of iliac arteries, without involvement of the aorta, is rare. Only few cases of endovascular treatment of this condition are reported in the current literature. We report false-lumen embolization strategy as an adjunct to stent-grafting of the true lumen. CASE REPORT: A 68-year-old male patient was admitted to our institution with the incidental finding of an isolated iliac dissection with a false lumen aneurysm. He was electively treated with successful segmental iliac stent-grafting to cover the primary entry tear in the common iliac artery...
