Acute kidney injury (AKI) after surgery or intervention is an important complication that may impact mortality, morbidity, and health care costs. Endovascular procedures are now performed routinely for a variety of pathologies that were traditionally treated with open surgery because randomized trials comparing endovascular and open surgery have shown at least equally good results and reduced complication and hospitalization rates with endovascular techniques. However, endovascular procedures have been associated with an increased risk for postoperative AKI, predominantly owing to contrast nephrotoxicity...

Accurate estimation of peak wall stress (PWS) is the crux of biomechanically motivated rupture risk assessment for abdominal aortic aneurysms aimed to improve clinical outcomes. Such assessments often use the finite element (FE) method to obtain PWS, albeit at a high computational cost, motivating simplifications in material or element formulations. These simplifications, while useful, come at a cost of reliability and accuracy. We achieve research-standard accuracy and maintain clinically applicable speeds by using novel computational technologies...

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)...

We describe the case of a 23-year-old white female, 10-12 weeks pregnant, with a history of intravenous drug use and a recently diagnosed pneumonia, who was found deceased in her bed after a night of sleep. Although postmortem serum toxicology tested positive for alprazolam, tetrahydrocannabinol, and morphine, the ultimate cause of death was determined to be cardiac tamponade secondary to an isolated abscess in the ascending aorta. The patient had several risk factors for aortic rupture and cardiac tamponade including intravenous drug use, pneumonia, and pregnancy...

Open repair for infra-renal abdominal aortic and iliac artery aneurysms (AAAs) is a robust treatment. On the other hand, endovascular aneurysm repair (EVAR) has been widespread because of its less invasiveness. However, patients after EVAR frequently require postoperative radiographic examinations and may feel anxiety for their endoleaks. We prospectively evaluated Health-related Quality of Life of the patients with these two fashions using the 8-item Short Form (SF-8). From 2011 to 2013, 89 consecutive elective cases of AAAs were treated...

Background Loeys-Dietz syndrome (LDS) is a recently recognized autosomal dominant connective tissue disease. The manifestations of LDS include vascular tortuosity, scoliosis, craniosynostosis, aneurysm and aortic dissections. Clinical presentation A 35-year-old woman treated with Stanford type B aortic dissection and breast cancer was referred to us for Borden type II dural arteriovenous fistula (dAVF) draining to the vein of Galen, involving the midline of tentorium cerebelli. The dAVF was treated successfully by combined transarterial and transvenous embolization...

Abdominal aortic aneurysm (AAA) is a permanent expansion of the vessel wall with a high prevalence in those 65 years of age and older. Aneurysms are prone to dissection and rupture that carry a mortality rate of over 85%. Currently, surgical repair is the only option to treat this disease. The need to intervene prior to these events has set off a flurry of basic studies in an effort to understand the cellular and molecular mechanisms that govern AAA formation, progression and rupture. In the present study, the role of myeloid cells in contributing to AAA development has been confirmed...

BACKGROUND: Percutaneous endovascular aneurysm repair (PEVAR) has been increasingly employed in the endovascular treatment of abdominal aortic aneurysms. Furthermore, the percutaneous approach can be used with minimal sedation and local anesthesia in the majority of cases. The purpose of this study is to assess the safety and effectiveness of a "percutaneous first" approach to femoral access for EVAR. METHOD: From 2012 to 2014, PEVAR has been the preferred approach to femoral access for EVAR at our institution...

OBJECTIVE Thyroid disorder has been known to affect vascular function and has been associated with aortic aneurysm formation in some cases; however, the connection has not been well studied. The authors hypothesized that hypothyroidism is associated with the formation of cerebral aneurysms. METHODS The authors performed a retrospective case-control study of consecutive patients who had undergone cerebral angiography at an academic, tertiary care medical center in the period from April 2004 through April 2014...

Abdominal aortic aneurysm (AAA) is the progressive dilation of the abdominal aorta. Nicotine is reported to be associated with the development and rupture of AAA, but the pathological effects of nicotine on normal rat aorta have not been determined. We investigated pathological changes in the aortic wall of rats caused by the administration of nicotine. Nicotine administration weakened the vascular wall, increased gelatinolytic activity and promoted the destruction of elastin and collagen in the rat abdominal aorta...

Aneurysms of the sinus of Valsalva (ASV) are rare, with an incidence ranging from 0.1% to 3.5% of all congenital cardiac defects and a prevalence of 0.009% in an autopsy series.ASVs occur much more frequently in the right coronary sinus of Valsalva. Previous reports, based on necropsy and cardiac surgery findings, estimated that 20% of ASVs are unruptured. Patients with an unruptured ASV may remain asymptomatic for a long period of time until rupture. They may also presented with dyspnea, palpitation, and angina-like chest pain...

Aortic dissection is a life threatening cardiovascular catastrophy. Its incidence estimated to 5-6 cases per 100,000 patients/year. The intimal tear happens at the ascending aorta in Type A, meanwhile at the aortic isthmus in Type B, but entry point may develop anywhere alongside the entire aorta. All types may affect a short aortic segment resulting in a localized false aneurysm, others separate the intimal layer at longer extension down to the visceral segment and far beyond to the femoral arteries. Dissection of orifices of side branches may lead to cerebral, upper extremity, spinal, visceral, renal and lower extremity malperfusion...
