Multiple arterial aneurysms in association with aberrant brachial arterial anatomy and hemodialysis fistulas.

This work describes two cases of multiple aneurysms of aberrant brachial arterial supply in association with ipsilateral hemodialysis fistulas. In the first case, a 38-year-old man presented with acute thrombosis of an aneurysmal left brachioradial artery. In the second case, a 34-year-old man was referred with the diagnosis of aneurysmal left brachiocephalic fistula.

Meta-Analysis of Genome-Wide Association Studies for Abdominal Aortic Aneurysm Identifies Four New Disease-Specific Risk Loci.

Rationale: Abdominal aortic aneurysm (AAA) is a complex disease with both genetic and environmental risk factors. Together, 6 previously identified risk loci only explain a small proportion of the heritability of AAA.

Objective: To identify additional AAA risk loci using data from all available genome-wide association studies.

Endovascular repair of a mycotic thoracic aortic aneurysm in a patient with aortic coarctation.

This report describes the management of a 28-year-old female patient who presented with septicemia and mediastinal mass-effect secondary to a proximal mycotic aneurysm of the descending aorta. The patient had an infected bicuspid aortic valve, aortic coarctation, and a left vertebral artery arising directly from the aortic arch. Evidence of disseminated embolization affecting her posterior cerebral circulation, the left axillary, and the superior mesenteric arteries was noted.

Quantitative Determination of three Angiotensin-II-receptor Antagonists in Presence of Hydrochlorothiazide by RP-HPLC in their Tablet Preparations.

Losartan potassium, Valsartan , Telmisartan and Irbesartan are angiotensin-II-receptor antagonists (ARA II) group which used in treatment of hypertension alone or in combination with other drugs mainly Hydrochlorothiazide. RP- HPLC method was developed for the assay of three angiotensin-II-receptor antagonists (ARA-IIs) in presence of Hydrochlorothiazide. The method was performed by reversed phase high performance liquid chromatography using a mobile phase which is consisted of 0.

A variant in LDLR is associated with abdominal aortic aneurysm.

Background: Abdominal aortic aneurysm (AAA) is a common cardiovascular disease among older people and demonstrates significant heritability. In contrast to similar complex diseases, relatively few genetic associations with AAA have been confirmed. We reanalyzed our genome-wide study and carried through to replication suggestive discovery associations at a lower level of significance.

Abdominal aortic aneurysm is associated with a variant in low-density lipoprotein receptor-related protein 1.

Abdominal aortic aneurysm (AAA) is a common cause of morbidity and mortality and has a significant heritability. We carried out a genome-wide association discovery study of 1866 patients with AAA and 5435 controls and replication of promising signals (lead SNP with a p value < 1 × 10(-5)) in 2871 additional cases and 32,687 controls and performed further follow-up in 1491 AAA and 11,060 controls. In the discovery study, nine loci demonstrated association with AAA (p < 1 × 10(-5)).

Transverse minilaparotomy for open abdominal aortic aneurysm repair.

Introduction: Traditional open surgical repair for abdominal aortic aneurysm (AAA) is a major procedure with a relatively high risk of perioperative morbidity. This article describes the results of minimally invasive open AAA repair through a transverse left upper quadrant minilaparotomy.

Methods: Between January 2007 and June 2010, 83 consecutive patients (77 men) underwent elective or urgent repair of a nonruptured AAA through a horizontal transperitoneal left upper quadrant minilaparotomy.

An analysis of drug modulation of abdominal aortic aneurysm growth through 25 years of surveillance.

Background: A modest (41%) reduction in abdominal aortic aneurysm (AAA) growth rate is likely to delay AAA-related events (surgery or rupture) by 5 years, making the notion of AAA medical treatment very appealing. Randomized controlled trials of commonly used existing medications are expensive and ethically questionable. This study reviewed the independent associations of commonly used medications and AAA growth during a 25-year period of AAA surveillance.

Assessment of the association between genetic polymorphisms in transforming growth factor beta, and its binding protein (LTBP), and the presence, and expansion, of Abdominal Aortic Aneurysm.

Objectives: Abdominal Aortic Aneurysm (AAA) has a strong genetic predisposition. Transforming growth factor beta 1 (TGF-beta1) is a causal factor in ascending aortic dilatation; however, a role in AAA pathology is unclear. The aim of the study was to determine whether genes coding TGF-beta and its binding protein are associated with the presence and expansion of AAA.

Sequence variant on 9p21 is associated with the presence of abdominal aortic aneurysm disease but does not have an impact on aneurysmal expansion.

Abdominal aortic aneurysm (AAA) is among a number of vascular disorders to be recently associated with a common allelic variant situated on chromosome 9p21. To further assess the significance of this region of the genome in AAA development, we genotyped the sequence variation tagged by rs10757278 in two geographically independent cohorts of patients and compared them to matched controls. We also assessed the impact of this variant on AAA growth rate in cohorts with a median surveillance period of 3.

Angiotensin II type 1 receptor 1166C polymorphism is associated with abdominal aortic aneurysm in three independent cohorts.

Objective: Although polymorphic variations in genes of the RAS system have previously been associated with susceptibility to AAA, such studies have been significantly limited by small sample sizes. This study was undertaken, using the largest case series yet reported, to determine whether common genetic variants of the RAS are associated with either susceptibility or severity of AAA.

Methods And Results: The frequencies of 4 common genetic variants of genes related to the renin-angiotensin system were investigated in 3 geographically distinct, but ethnically similar, case-control cohorts, resulting in comparison of 1226 AAA cases with 1723 controls.

Screening and ultrasound surveillance of large abdominal aortic aneurysms do not improve suitability for endovascular repair.

Objective: The effect of population screening for abdominal aortic aneurysm (AAA) disease on morbidity and mortality has been comprehensively studied and reported. However, the effect of early AAA detection on suitability for endovascular aneurysm repair (EVAR) remains unknown. Considering the importance of such an effect on future health economics, we sought to assess the possible effect of AAA ultrasound surveillance on suitability for EVAR.
