BACKGROUND Midaortic syndrome (MAS) is a rare vascular anomaly characterized by segmental narrowing of the distal descending thoracic or abdominal aorta. Renal or visceral arteries may also be affected to varying degrees. MAS is often associated with renovascular hypertension, and requires early intervention. When medical therapy and percutaneous interventions fail to control hypertension, surg...

background: numerical study of angulation effects of renal arteries on blood flow has been of great interest for many researchers. objective: this paper aims at numerically determining the angulation effects of stenosed renal arteries on blood flow velocity and renal mass flow. method: an anatomically realistic model of abdominal aorta and renal arteries is reconstructed from ct-scan images and...

A 64-year-old woman was admitted to the hospital for an acute right leg pain. Clinical examination, revealing a slightly discolored foot with no pedal pulse, went in favor of a limb embolism. Her past medical history was relevant for an endometrial adenocarcinoma treated by radical surgery and adjuvant chemotherapy. The patient confessed being on a 6-week-long course of low-molecular-weight hep...

OBJECTIVE The pathogenesis of abdominal aortic aneurysm (AAA) formation is poorly understood. We investigated the relationship between carotid, femoral, and coronary atherosclerosis and abdominal aortic diameter, and whether atherosclerosis was a risk marker for AAA. METHODS AND RESULTS Ultrasound of the right carotid artery, the common femoral artery, and the abdominal aorta was performed in...

Background The best treatment of abdominal aorta aneurysms of the segments below the emergency of the renal arteries are still under discussion. In literature there are several studies that compare the retroperitoneal (R.P.) approach with the transperitoneal (T.P.) one or that suggest their possible variations. The R.P. approach offers the possibility of treating patients with hostyle abdomen (...

Type IV thoracoabdominal aortic aneurysms (TAAAs) affect the aorta between the diaphragm and aortic bifurcation (Fig. 1). For technical reasons, the aneurysms affecting only the part of aorta from which visceral arteries arise are also categorized as type IV. The level of difficulty of surgical treatment for type IV TAAAs lies between that of type II, which involve descending thoracic and abdom...

Abdominal aortic aneurysm, with its incidence approaching approximately 8% in the population, accounts for more than 8,000 deaths annually in the United States. It is a multifactorial disease associated with atherosclerosis. Age, male gender, smoking, and the family history of abdominal aortic aneurysm are thought to be the risk factors for the disease (Ashton et al., 2002, Fleming et al., 2005...

We present the case of a 29-year-old pregnant woman with Marfan syndrome who presented an aortic root diameter of <45 mm at the start of gestation with no other abnormalities. She had been diagnosed of Marfan syndrome 2 years previously as a result of a family study. The patient underwent a follow-up cardiologic examination before becoming pregnant. At that time, the aortic root diameter at the...

Introduction In the treatment of complex aneurysms, debranching is an extra-anatomical revascularization of visceral arteries followed by endograft coverage of the thoracoabdominal aorta. It eliminates the need for a thoracotomy and aortic clamping, but requires the performance of several technically demanding visceral anastomosis. In 2008, Lachat described visceral revascularization with the u...

“Atypical” aortic coarctation (AAC) is a rare clinical entity that includes involvement of the ascending thoracic aorta, the descending thoracic aorta distal to the aortic isthmus, and the abdominal aorta. Abdominal aortic coarctation is present in 1% to 2% of all patients with aortic coarctation and is an unusual cause of essential hypertension in adults. AAC is caused by focal stenosis or a h...
