Recently developed flow diverters, such as the pipeline embolization device (PED), allow for safe and efficacious treatment of giant intracranial aneurysms, with high occlusion rates and a low incidence of complications. However, incomplete obliteration after PED treatment may lead to aneurysm regrowth and delayed rupture. Herein, we report a case of a partially thrombosed giant aneurysm of the cavernous internal carotid artery that showed progressive recanalization at 1-3 months after application of a PED...

BACKGROUND: Treatment of ophthalmic segment aneurysms (OSA) remains challenging. Flow diverter stents (FDS) have evolved as a promising endovascular treatment option for aneurysms of the internal carotid artery and are associated with high occlusion rates and a favorable morbidity and mortality profile. OBJECTIVE: To determine safety and efficacy of FDS for OSA in a large, multicenter cohort. METHODS: A retrospective analysis of prospectively maintained databases of 127 consecutive patients harboring 160 OSA treated with FDS was performed...

BACKGROUND: Superior cerebellar artery (SCA) aneurysms are usually grouped with aneurysms that arise from the upper basilar artery or more broadly, the posterior circulation. However, the SCA aneurysm has distinctive anatomy that facilitates safe surgical management, notably few associated perforating arteries, and excellent exposure in the carotid-oculomotor triangle. OBJECTIVE: To demonstrate the outcomes of patients treated with microsurgery in a continuous surgical series...

Giant cell arteritis ( GCA) is an inflammatory vasculopathy affecting large and middle-sized vessels , specifically cranial arteries derived from carotid artery. Isolated extracranial vessel involvement can occur. Interest in extravascular manifestations is recently increasing because of diffusion of sensitive and specific imaging tools such as 18FDG PET TC . Patients have an increased relative risk of severe infection. Listeria monocytogenes infection risk is increased, and vascular system involvement and graft infection have been, even though rarely, reported...

Elevated homocysteine (Hcy) levels are predictors of cardiovascular disease (CVD). Hyperhomocysteinemia has also been associated with total and CVD mortality. However, whether Hcy is just a marker or plays a causal role in CVD remains to be elucidated. In this narrative review, we discuss the associations between Hcy and non-cardiac vascular diseases, namely stroke, peripheral artery disease (PAD), carotid artery disease, chronic kidney disease (CKD), atherosclerotic renal artery stenosis (ARAS), abdominal aortic aneurysm (AAA) and erectile dysfunction (ED)...

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...

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)]...

BACKGROUND: Extracranial carotid artery aneurysm (ECAA) is a rare clinical entity, and no standard treatment strategy has been established for this condition. METHODS: Data from three patients who underwent surgical treatment of enlarging giant ECAAs were retrospectively reviewed. Based on the collateral status, as evaluated by preoperative digital subtraction angiography (DSA), surgical strategy was stratified into (1) high flow bypass followed by cervical ICA (internal carotid artery) ligation, when the collateral status was judged as poor/fair or (2) direct cervical repair with patch application after aneurysmal wall resection when the collateral status was judged as robust...

OBJECTIVE Blood-blister aneurysms (BBAs) of the internal carotid artery (ICA) have a poor natural history associated with high morbidity and mortality. Currently, both surgical and endovascular techniques are employed to treat BBAs; thus, the authors sought to perform a meta-analysis to compare the efficacy and safety of these approaches. METHODS A literature search of PubMed, MEDLINE, and Google Scholar online databases was performed to include pertinent English-language studies from 2005 to 2015 that discussed the efficacy and safety of either surgical or endovascular therapies to treat BBAs...

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...

BACKGROUND: Alternative access for thoracic endovascular aortic repair (TEVAR) has been explored for patients with unsuitable femoral and iliac access, but few cases of transapical access have been described. We report our experience with transapical access for various aortic pathologies. METHODS: We reviewed six cases undergoing transapical access for endovascular repair of thoracic aortic pathology between December 2013 and August 2015. Five patients had an aortic arch aneurysm and 1 patient presented with Stanford type A subacute aortic dissection...

BACKGROUND: Aneurysms of the external carotid artery represent approximately 2% of cervical carotid aneurysms with the majority being traumatic pseudoaneurysms. The diagnosis, treatment, and follow-up of such lesions are completely individualized as there is a paucity of literature available for guidance. CASE DESCRIPTION: We report the case of an 83-year-old woman with an 8-week history of headache in the occipital region, transient episode of gait disturbance, and pulsatile tinnitus on the right...

Dissecting aneurysms in the anterior cerebral artery (ACA), although rare, can cause ischemic and/or hemorrhagic stroke. Hemorrhagic dissecting aneurysms in the A1 portion of the ACA are often associated with a poor prognosis. We retrospectively investigated three rare cases of hemorrhagic dissecting aneurysms in the A1 portion. Dissecting aneurysms were diagnosed by carotid angiography or computed tomography angiography to visualize morphological changes in the vessel. All patients presented with diffuse subarachnoid hemorrhage...

INTRODUCTION: Flow diversion has become a popular treatment option for a variety of cerebral aneurysms. We sought to compare conscious sedation and general anesthesia for flow diverter placement in a matched cohort study. MATERIALS AND METHODS: Patients who underwent flow diverter placement under conscious sedation were matched on the basis of age, sex, American Society of Anesthesiologists (ASA) classification, aneurysm location, and aneurysm size with patients who received general anesthesia...

Mycotic aneurysms and prosthetic graft infections are traditionally treated with excision of the infected tissue or graft, often requiring anatomical or extra-anatomical bypass, carrying significant morbidity and mortality. Currently, the role of endovascular repair without excision in this setting has yet to be defined. We present two case scenarios whereby mycotic pseudoaneurysms were successfully treated with endovascular stent graft coverage, and to present an in-depth review of endovascular in-situ revascularziation in the treatment of arterial and graft infections...

Cerebral artery aneurysm rupture is usually associated with significant subarachnoid hemorrhage; however, there are rare cases where there is a lack of hemorrhage into the subarachnoid space. While subdural hemorrhage can occur with ruptured aneurysms, isolated subdural hemorrhage is more often associated with trauma. In this case, a 51-year-old obese woman, who recently visited an Urgent Care Center for elevated blood pressure, was found dead roughly a month later. She had been complaining of headaches, and received medication for her blood pressure at the visit...

Fibromuscular dysplasia is a nonatherosclerotic and non-inflammatory vascular disease with primary lesion of renal and internal carotid arteries. We present a neonatal case of fibromuscular dysplasia who died on the second day of life. The newborn suffered from fibromuscular dysplasia of the coronary arteries and a congenital heart defect. The interesting feature of this case was the formation of aneurysms of the coronary arteries with pulmonary atresia. This case demonstrates a casuistically rare form of association between fibromuscular dysplasia of the coronary arteries and pulmonary artery atresia...
