Abdominal aortic aneurysm (AAA) is most commonly defined as a maximal diameter of the abdominal aorta in excess of 3 cm in either anterior-posterior or transverse planes or, alternatively, as a focal dilation ≥ 1.5 times the diameter of the normal adjacent arterial segment. Risk factors for the development of AAA include age > 60, tobacco use, male gender, Caucasian race, and family history of AAA. Aneurysm growth and rupture risk appear to be associated with persistent tobacco use, female gender, and chronic pulmonary disease...

The most common primary cardiac tumor is myxoma, typically originating in the left atrium. Emboli to the central nervous system can cause cerebral infarction or, rarely, seed tumor growth within vessel walls, causing myxomatous aneurysms. Fewer than 60 myxomatous aneurysms have been reported, including 2 cases in children. Here, the authors describe 2 different growing myxomatous aneurysms in a child successfully managed using a combined multidisciplinary approach. A 12-year-old boy developed a sudden headache, diplopia, gait instability, and speech difficulty...

Internal jugular vein (IJV) aneurysm is a rare entity, and a thrombosed aneurysm poses diagnostic and management challenges. We came across a 53-year-old woman who presented with fever, vomiting and right neck swelling for a week. Laboratory investigations showed neutrophilic leucocytosis, raised acute phase reactant and blood culture yielded Klebsiella pneumoniae Ultrasound and contrast-enhanced CT neck revealed a large fusiform aneurysm of the right IJV with filling defect extending from the aneurysm into the right transverse sinus...

A 71-year-old woman presented with a sudden onset of headache and vomiting. Computed tomography(CT)showed diffuse subarachnoid hemorrhage(SAH)that was more severe on the right side. Three-dimensional CT angiography and right carotid angiography(CAG)demonstrated 2-mm microaneurysms at the middle cerebral artery(MCA)bifurcation and anterior communicating artery, with slight narrowing and dilatation of the M2 inferior trunk. Each microaneurysm was smooth, making it difficult to identify the bleeding source. Thus, surgery was postponed at the acute stage, and further investigation was planned...

Fenestration of a vertebral artery(VA)is a rare anomaly that has occasionally been associated with the formation of saccular aneurysms, whereas dissection of a limb of the fenestrated artery is an extremely rare occurrence. We report the case of a ruptured dissecting aneurysm of a fenestrated VA. A 56-year-old man presented with acute-onset headache followed by respiratory failure. Computed tomography(CT)revealed diffuse subarachnoid hemorrhage, and CT angiography(CTA)demonstrated fenestration of the left VA and a fusiform aneurysm of the dorsolateral limb of the fenestrated VA...

Isolated saccular compared to fusiform aneurysm is considered to be a rare entity with challenges of its own. A 62-year-old female was diagnosed with a case of saccular aneurysm and penetrating atherosclerotic ulcer of the aortic arch. Additionally, she also had one vessel coronary artery disease and type B abdominal aortic dissection. She was then managed with open aortic arch repair and coronary artery bypass grafting. If required, elective endovascular repair will be done for the abdominal aorta on a later date...

In the contemporary era of aneurysm management, large fusiform aneurysms presenting with subarachnoid hemorrhage (SAH) remain particularly challenging lesions to successfully manage. We describe a staged, multimodal treatment strategy for a 71-year-old patient who presented with a large ruptured fusiform aneurysm of the supraclinoid internal carotid artery (ICA) and a fetal posterior communicating artery which originated from the inferomedial aspect of the aneurysm. In the first stage, we performed a partial microsurgical clip reconstruction of the fusiform aneurysm and secured its rupture site, which was identified intraoperatively...

A 47-year-old man with HIV infection presented 10 years after initial secondary syphilis diagnosis and treatment for routine follow-up. His HIV was well controlled on antiretroviral therapy. Rapid plasma reagin was 1:1, and TP-PA was reactive. Physical examination revealed a wide pulse pressure, a systolic murmur, and an early diastolic decrescendo murmur. Echocardiogram revealed moderate to severe aortic regurgitation, and subsequent computed tomography angiogram showed a 6.8-cm fusiform aneurysm of the proximal ascending aorta...

Pure fusiform aneurysms without dissection are considered to have a low risk of rupture. Furthermore, aneurysm wall with atherosclerotic change tends to be less susceptible to rupture. We present a rare case of multiple atherosclerotic fusiform aneurysms associated with repeated subarachnoid hemorrhage(SAH)during a 9-year observation period. A 34-year-old woman was admitted to our hospital because of SAH. SAH with a temporal hematoma due to a fusiform aneurysm of the right middle cerebral artery(MCA)was detected using computed tomography(CT)...

The premammillary artery (PMA) is a branch of the posterior communicating artery (PCoA). While the PMA is known to originate from the PCoA as demonstrated by most anatomical studies, it originates directly from the internal carotid artery in approximately 1% of patients. Cerebral aneurysms associated with the PMA have rarely been reported. We report an extremely rare case of a ruptured PMA aneurysm that was managed using endovascular treatment.

BACKGROUND AND IMPORTANCE: Fusiform intracranial aneurysms remain challenging lesions to treat. These aneurysms have historically required bypass procedures or clip remodeling constructs for cure. Recently, endovascular specialists have reported experience with flow diversion for complex fusiform aneurysms of the vertebrobasilar system, with mixed results. Vascular anatomy for anterior circulation fusiform aneurysms may make these lesions more amenable to flow diversion and embolization procedures; however, published experience with these techniques is lacking...

BACKGROUND AND PURPOSE: Aneurysms in various arterial beds have common risk- and genetic factors. Data on the correlation of extracranial carotid artery aneurysms (ECAA) with aneurysms in other vascular territories are lacking. We aimed to investigate the prevalence of ECAA in patients with an intracranial aneurysm (IA). METHODS: We used prospectively collected databases of consecutive patients registered at the University Medical Center Utrecht with an unruptured intracranial aneurysm (UIA) or aneurysmal Subarachnoid hemorrhage (SAH)...

BACKGROUND: Posterior cerebral artery aneurysms are uncommon, with an occurrence rate of less than 1% of intracranial aneurysms. They have various shapes, including saccular and fusiform. Dissecting aneurysms may occur in distal posterior cerebral artery and they may affect the whole artery. Endovascular therapy is considered as a safe method of treatment and there are different techniques for endovascular therapy. SUMMARY: Posterior cerebral artery aneurysms are uncommon...

Objectives The Low-profile Visualized Intraluminal Support (LVIS) device is a flexible intracranial stent. The first generation of this system had significant challenges in consistently providing good wall apposition and aneurysm neck coverage. A new modified LVIS, LVIS Blue (Blue), has been developed to address these issues. The purpose of this study is to report a laboratory comparison of wall apposition and aneurysm neck coverage between the original LVIS and Blue. Methods In bench-top experiments, we noted the visual appearance of the devices and evaluated changes in stent cell angles, neck coverage surface area (%), and stent cell crossing profile for microcatheters using a fusiform aneurysm model...
