INTRODUCTION Several studies have found an increased incidence of peripheral aneurysms in patients with an abdominal aortic aneurysm (AAA). The aim of this study was to determine whether screening for popliteal aneurysms should be part of an AAA screening programme. SETTING A community-based AAA screening programme. METHODS The diameters of the internal abdominal aorta and both popliteal ar...

OBJECTIVE Apoptosis of smooth muscle cells (SMCs) is a prominent pathological characteristic of abdominal aortic aneurysm (AAA). We have previously shown that SMC apoptosis stimulates proinflammatory signaling in a mouse model of AAA. Here, we test whether protein kinase C-δ (PKCδ), an apoptotic mediator, participates in the pathogenesis of AAA by regulating apoptosis and proinflammatory signal...

BACKGROUND Endovascular repair of aorta in comparison to open surgery has a low early operative mortality rate, but its long-term results are uncertain. OBJECTIVES The current study describes for the first time our initial four-year experience of elective endovascular aortic repair (EVAR) at Tehran heart center, the first and a major referral heart center in Iran, as a pioneer of EVAR in Iran...

Recent reviews state that a circulating biomarker predicting aortic rupture risk would be a powerful tool to stratify patients with small screen-detected abdominal aortic aneurysm (AAA). In a current proteomic pilot-study elevated levels of the enzyme Glycosylphosphatidylinositol-specific phospholipase D (GPI-PLD) was shown in patients with small AAA compared with controls without aneurysm. In ...

Acute thrombosis of an abdominal aortic aneurysm is a rare but devastating surgical emergency. We present the first case of a patient with sudden thrombosis of an AAA delayed (more than 24 h) after removal of an intra-aortic balloon pump. Treatment options include open surgical repair, axillobifemoral grafting or endovascular aortic repair. The patient received an aorto-bifemoral graft. The ass...

Renal artery aneurysm (RAA) is uncommon, and the coexistence of an abdominal aortic aneurysm (AAA) is an extremely rare condition with potentially high life-threatening mortality in case of rupture. Aneurysms can be treated by endovascular intervention or open surgery. Although most of aneurysms are treated by endovascular intervention, open surgery is often necessary for RAAs associated with t...

Abdominal aortic aneurysm (AAA) is a common disease among elderly individuals. However, the precise pathophysiology of AAA remains unknown. In AAA, an intraluminal thrombus prevents luminal perfusion of oxygen, allowing only the adventitial vaso vasorum (VV) to deliver oxygen and nutrients to the aortic wall. In this study, we examined changes in the adventitial VV wall in AAA to clarify the hi...

We report a rare case of mycotic abdominal aortic aneurysm associated with Campylobacter fetus. A 72-year-old male admitted to the hospital because of pain in the right lower quadrant with pyrexia. The enhanced abdominal computed tomography (CT) examination showed abdominal aortic aneurysm (AAA) measuring 50 mm in maximum diameter and a high-density area of soft tissue density from the right la...

BACKGROUND The majority of infrarenal abdominal aortic aneurysm (AAA) repairs in the United States are performed with endovascular methods. Baseline aortoiliac arterial anatomic characteristics are fundamental criteria for appropriate patient selection for endovascular aortic repair (EVAR) and key determinants of long-term success. We evaluated compliance with anatomic guidelines for EVAR and t...

In abdominal aortic aneurysm (AAA), the rupture of tissue is directly related to wall stress. Thus, investigation maximum stress a necessary procedure predict in AAA. this study, computational simulations were performed investigate correlation between peak (PWS) and AAA geometry. The Holzapfel model various orientations collagen fibers thicknesses layers aorta employed simulation. material cons...
