the division of the aorta into right and left common iliac arteries; it occurs at the level of the fourth lumbar vertebral body.

D-1, Male, 67-year-old, CT scan of abdomen showing pseudoaneurysm formation at the abdominal aortic bifurcation and the initial segment of the right iliac artery.
Therefore, although most physicians' preference support the use of ultra-low profile endografts in such cases, we would strongly advocate the routine use of a balloon-expandable stent support to avoid compression of the iliac limbs in cases of tight aortic bifurcation or severe iliac angulation/tortuosity, as illustrated in the example (Fig.).
CT abdominal aortogram showed large thrombus seen in the abdominal aorta starting at the level of renal arteries completely occluding the aorta and common iliac arteries with no blood flow seen beyond the renal artery level up to the aortic bifurcation; moderate to severe stenosis is noted at the origin of both renal arteries because of thrombus (Figures 2(a) and 2(b)).

To determine PWVao, the Arteriograph uses the physiological behaviour of the wave reflection; the ejected direct (first systolic) pulse wave is reflected back mostly from the aortic bifurcation. The device measures the time interval between the peaks of the direct (first) and reflected (late) systolic wave (return time).
Two balloon expandable (BE) covered stents (Bentley Innomed GmbH, Germany, 10 x 57 mm (right side) and 9 x 57 mm (left side)) were initially advanced and deployed at aortic bifurcation. An aortography was performed, which showed residual thrombus at the distal end of both common iliac arteries.
A computerized tomography angiogram (CTA) scan demonstrated a 6.5 cm Crawford type III TAAA extending from the midthoracic aorta to the aortic bifurcation with no evidence of any leak.
The pulse wave at the radial artery is the superposition of the forward wave, produced by the heart, and the reflected wave from the aortic bifurcation at the iliac artery [15].
Contrast-enhanced CT abdomen and pelvis revealed a lobulated soft tissue lesion extending from the aortic bifurcation to the anterior margin of L5 that measured up to 8 cm in craniocaudal dimension, and contained peripheral ring like foci of calcification.
In this study, we aimed measuring the values of the morphometric data, such as distance and location of the IVC according to the lumbar vertebra, the aortic bifurcation (AB) and the AA and comparing with the demographic values ol sex, height, body weight and age.
The contrast-enhanced CT of the abdomen demonstrated a rind of soft tissue covering the lateral and posterior margins of the aorta extending from below the level of the renal arteries down to the aortic bifurcation and proximal right common iliac artery (Figure 10).
Utilizing the umbilicus as the initial entry point--often desirable in minimally invasive surgery--is frequently not possible in morbidly obese patients because as BMI increases, the umbilicus migrates toward the pubic bone and away from the aortic bifurcation. In patients who were overweight (BMI greater than 25), Dr.
