Ruptured aneurysm

Vaner Koksal, Selim Kayaci
INTRODUCTION: The treatment of giant intracranial aneurysms is one of the most challenging cerebrovascular problems of neurosurgery. We report the rupture of a giant, lobulated, and almost completely thrombosed middle cerebral artery (MCA) aneurysm that is the ninth such report in the literature. We also investigated additional solutions used in the treatment of this patient. CASE PRESENTATION: A 58-year-old man had been admitted with headache 8 years previously (in 2005), and a giant MCA aneurysm was detected...

We report a contained rupture of a right coronary sinus of Valsalva aneurysm, in which repair resulted in symptomatic improvement. Patients often present with symptoms secondary to rupture of the sinus of Valsalva aneurysm into one of the cardiac chambers, or secondary to the compression of adjacent structures. Whereas sinus of Valsalva aneurysms and their rupture are well reported in the literature, contained ruptures have been described only rarely. In those cases, symptoms often arose from compression of adjacent structures...

Behcet disease (BD) is a chronic systemic vasculitis and considered as an autoimmune disease. Although rare, BD can be fatal due to ruptured vascular aneurysms or severe neurological complications. To date, no known biomarker has been reported for this disease, making it difficult to diagnosis in the clinics. To undertake this challenge, we employed the HuProt arrays, each comprised of~20,000 unique human proteins, to identify BD-specific autoantibodies using a Two-Phase strategy established previously. In Phase I, we profiled the autoimmunity on the HuProt arrays with 75 serum samples collected from 40 BD patients, 15 diagnosed autoimmune patients who suffer from Takayasu arteritis (TA; N=5)), ANCA associated vasculitis(AAV; N=5), and Sjogren's syndrome(SS; N=5), and 20 healthy subjects, and identified 20 candidate autoantigens that were significantly associated with BD...

INTRODUCTION: Cerebral vasospasm following subarachnoid hemorrhage (SAH) is the single most important cause of neurological decline following successful treatment of the ruptured aneurysm. Here, we report safety and efficacy of non-compliant balloon angioplasty for the treatment of cerebral vasospasm. METHODS: Three major academic institutions in the United States provided data on cerebral vasospasm treated with non-compliant balloon angioplasty between October 2004 and February 2016...

OBJECTIVE: Rupture of an intracranial aneurysm usually presents with an acute onset, requires multidisciplinary intensive care treatment, and the overall death and disability rates are high. The ABO blood type is known to play an important role in hemostasis, thrombosis and vascular NO response. The aspect of ABO blood type in onset, clinical progress and outcome after SAH are to date largely unexplored. We conducted this study to elucidate the association of ABO blood type on the occurrence and outcome of aneurysmal SAH...

BACKGROUND: Recent studies have reported the use of stent-assisted coiling (SAC) for wide-necked aneurysms in patients with acute subarachnoid hemorrhage (SAH). This study attempted to determine whether it is safe and efficient to use SAC for wide-necked aneurysms during post-SAH days 4-10. METHODS: We reviewed 126 consecutive patients with ruptured wide-necked aneurysms who underwent SAC. The patients were classified into the early cohort (SAC was performed within post-SAH days 0-3) and late cohort (SAC was performed within post-SAH days 4-10)...

BACKGROUND: True aneurysms of the gastroduodenal (GDA) and pancreaticoduodenal (PDA) arteries have been attributed to increased collateral flow due to tandem celiac artery stenosis or occlusion. While GDA/PDA aneurysm exclusion is recommended because of the high reported risk of rupture, it remains uncertain whether simultaneous celiac artery reconstruction is necessary to preserve end-organ flow. STUDY DESIGN: A retrospective analysis of consecutive patients admitted 1996-2015 with true aneurysms of the GDA or PDA...

OBJECTIVE: To study the beneficial place for the treatment of ruptured abdominal aortic aneurysms (RAAAs). METHOD: A retrospective chart review of consecutive RAAA patients was performed. Patients were divided into two groups: direct group and transfer group. We retrospectively reviewed patients' hospital charts and recorded various clinical factors apparent on presentation. The primary consequence was mortality during hospitalization, and some other parameters such as duration of intensive care unit (ICU)...

Angiogenesis and inflammation are implicated in aortic aneurysm and atherosclerosis and regulated by angiopoietin-2 (Angpt2). The effect of Angpt2 administration on experimental aortic aneurysm and atherosclerosis was examined. Six-month-old male apolipoprotein E deficient (ApoE(-/-)) mice were infused with angiotensin II (AngII) and administered subcutaneous human Fc-protein (control) or recombinant Angpt2 (rAngpt2) over 14 days. Administration of rAngpt2 significantly inhibited AngII-induced aortic dilatation and rupture of the suprarenal aorta (SRA), and development of atherosclerosis within the aortic arch...

Mitral valve aneurysms are rare and occur most commonly in association with aortic valve endocarditis. Transesophageal echocardiography is the most sensitive imaging modality for the diagnosis of this entity and its potential complications, such as leaflet rupture and mitral regurgitation, which mandate prompt surgical intervention. We present the case of a 70-year-old male patient with aortic valve endocarditis complicated with a ruptured aneurysm of the anterior mitral valve leaflet and associated severe mitral regurgitation, diagnosed by transesophageal echocardiography, with impressive images...

Abdominal aortic aneurysms (AAAs), which commonly occur among elderly individuals, are accompanied by a risk of rupture with a high mortality rate. Although eicosapentaenoic acid (EPA) has been reported to prevent AAA formation, the mechanism by which EPA works on vascular smooth muscle cells is unknown. This study aimed to investigate the mechanism by which orally-administered EPA prevents the formation of severe AAAs that develop in Osteoprotegerin (Opg) knockout (KO) mice. In the CaCl2-induced AAA model, EPA attenuated the enhanced progression of AAAs in Opg-KO mice, including the increase in aortic diameter with destruction of elastic fibers in the media...

The use of live attenuated intravesicular Bacillus Calmette-Guerin (BCG) therapy is a generally accepted safe and effective method for the treatment of superficial transitional cell carcinoma (TCC) of the bladder. Although rare, < 5% of patient's treated with intravesicular BCG therapy may develop potentially serious complications, including localized infections to the genitourinary tract, mycotic aneurysms and osteomyelitis. We present here a case of a 63-year-old male who developed left coronary and multiple peripheral M...

BACKGROUND AND IMPORTANCE: As the use of flow-diverting stents (FDSs) for intracranial aneurysms expands, a small number of case reports have described the successful treatment of blister aneurysms of the internal carotid artery with flow diversion. Blister aneurysms are uncommon and fragile lesions that historically have high rates of morbidity and mortality despite multiple treatment strategies. We report a case of rebleeding after treatment of a ruptured blister aneurysm with deployment of a single FDS...

In adult the patent ductus arteriosus is a rare condition associated sometimes with lethal complications. We describe the case of a 44-year-old woman with a history of systemic lupus erythematosus admitted to our hospital with hoarseness and severe dyspnea. Clinical imaging examinations indicated a saccular aneurysm within a persistent ductus arteriosus with signs of impending rupture. Patient was not considered suitable for transcatheter closure and therefore she underwent open aortic repair. The procedure was uneventful and any significant complications occurred during postoperative course...

Abdominal aortic aneurysm (AAA) rupture is a local event in the aneurysm wall that naturally demands tools to assess the risk for local wall rupture. Consequently, global parameters like the maximum diameter and its expansion over time can only give very rough risk indications; therefore, they frequently fail to predict individual risk for AAA rupture. In contrast, the Biomechanical Rupture Risk Assessment (BRRA) method investigates the wall's risk for local rupture by quantitatively integrating many known AAA rupture risk factors like female sex, large relative expansion, intraluminal thrombus-related wall weakening, and high blood pressure...

RATIONALE: Atherosclerosis and aneurysms are leading causes of mortality worldwide. MicroRNAs (miRs) are key determinants of gene and protein expression, and atypical miR expression has been associated with a number of cardiovascular diseases; although their contributory role to atherosclerotic plaque and abdominal aortic aneurysm (AAA) stability are poorly understood. OBJECTIVE: To investigate whether miR-181b regulates TIMP-3 expression and affects atherosclerosis and aneurysms Methods and Results: Here, we demonstrate that miR-181b was over-expressed in symptomatic human atherosclerotic plaques and abdominal aortic aneurysms, and correlated with decreased expression of predicted miR-181b targets, TIMP-3 and elastin...
