Open repair of pararenal aortic aneurysms: operative

Surgical treatment of pararenal aortic aneurysms, if compared to open surgical repair of infrarenal aneurysms, is technically more demanding and characterized by problems related to organ ischemia, To better define challenges, risks, and results, we analyzed our experience with the treatment of para …

[Open repair for pararenal abdominal aortic aneurysm: the

Pararenal abdominal aortic aneurysm PRAAA includes two types of AAA : juxtarenal JRAAA and suprarenal SRAAA, JRAAA is defined as aneurysms that extend up to but do not involve the renal arteries, necessitating suprarenal aortic clamping for repair, SRAAA is defined as aneurysms that extend up to the superior mesenteric artery, involving one or both renal arteries to be repaired, The

Pararenal aortic aneurysms: The future of open aortic

Currently, endovascular repair is applicable to approximately 60% of all infrarenal abdominal aortic aneurysms AAAs, 1 The most common anatomic reason for unsuitability for endovascular AAA repair is lack of an adequate proximal implantation site as a result of aneurysm origin in the pararenal aorta, 1 Consequently, an increasing proportion of patients who undergo conventional open repair

Open Surgical Treatment of Pararenal and Suprarenal

Once the pararenal aorta has been exposed, isolating and occluding the renal and mesenteric arteries with microvascular clamps before proximal aortic clamping should decrease the risk of atheroembolic complications involving the kidneys and intestines, although this benefit has not been critically studied, A dominant cause of morbidity and a substantial cause of mortality following …

Hemodynamics and Oxygen Transport through Pararenal Aortic

Whenever the Sh number is smaller than the Damkholer number D a = K τ a/D, where K τ denotes the rate constant for the surface reaction 33 within the arterial wall, hypoxia occurs,22, 25, 33 Because the pararenal aorta lies close to thoracic aorta, D a is approximately 185, 25 Interestingly, the distribution of the Sh number is similar to that of the WSS , and previous studies have

Fenestrated Aortic Endografts: Juxtarenal and Pararenal Aortic Aneurysms, Fig, 18,1, Lowest renal artery—right renal, These aneurysms are most commonly due to degenerative atherosclerotic disease, Abdominal aortic aneurysms with short or absent infrarenal necks less than 10–15 mm are not suitable for treatment with standard “off-the

Anterior pararenal space

The anterior pararenal space is the portion of the retroperitoneum that lies between the posterior surface of the parietal peritoneum and the anterior reflection of the perirenal fascia,, Gross anatomy, It contains the duodenum D2 and D4, pancreas and retroperitoneal segments of the ascending and descending colon,It also contains the roots of the small bowel mesentery and …

Combined aortorenal reconstruction: is there an optimum

Objective: To determine the advantages and disadvantages of two different transabdominal approaches to expose the pararenal aorta; infacolic IC and medical visceral rotation MVR, Design: Retrospective study, Methods: We reviewed a consecutive series of concurrently treated patients undergoing combined aortorenal reconstruction using one of these two approaches IC n = 45; MVR n = 30,

Comparison of modern open infrarenal and pararenal

Pararenal aneurysm is defined as aneurysms that have no normal aorta between the upper extent of the aneurysm and the renal arteries, It can be classified into juxtarenal or suprarenal types, JAAA includes aneurysms that extend to just below the renal arteries without involving the renal arteries, whereas a suprarenal AAA includes that which involves at least one renal artery orifice, 10, A
