In MRA, the patient had stenosis of infrarenal aorta and the left renal artery
. The biopsy specimen showed a thickened intima, disruption of the internal elastic lamina, giant cells, and inflammatory changes consistent with Takayasu arteritis.
The lower pole of the kidney was supplied by the lower renal artery
(LRA) that was anastomosed to the external iliac artery during the original surgery.
Type I--Inferior segmental branch arises from the anterior division of renal artery
The locations of the seven treated TRAAs were on the renal artery
trunk proximal to the bifurcation (n=1), extrarenal on the bifurcation (n=2), extrarenal distal to the bifurcation point (n=3), and intrarenal on the branches distal to renal artery
thrombosis is a rare but very serious complication, which occurs in less than 1% of cases (Fig.
CE-MRA revealed 50% stenosis in the right subclavian artery and 55% stenosis in the left subclavian artery, with long-segment severe stenosis in the abdominal aorta extending into the proximal portion of the bilateral renal artery
Mural irregularities and thickening with significant contrast enhancement in the vascular walls were observed on performing CE-MRI, with black blood T1-weighted sequence strongly suggesting vasculitis.
(2-5) To the authors knowledge, no literature of any case demonstrating primary renal artery
aneurysm with duodenal and venocaval fistula exists, however secondary aneurysms with grafts in situ and intestinal fistula are found.
Atherosclerotic renal artery
stenosis (ARAS) is an important but often underestimated cause of hypertension.
This young patient had accidental findings of asymptomatic CHB, uncontrolled HTN with renal artery
stenosis, and complete thrombosis of the abdominal aorta.
Depending on clinical, electrocardiographic, biochemical, and angiographic evidence, the patient was diagnosed with the thromboembolic occlusion in the left renal artery
branches developing due to unknown origin.
An abdominal CT scan taken 3 weeks prior to admission showed a normal caliber left renal artery
(Figure 2(a)); however, an abdominal CT scan on admission revealed a 1.65 cm left renal artery
aneurysm (Figures 2(b) and 2(c)).
stenosis (RAS) is a cause of renovascular hypertension (RVHT) and ischemic nephropathy and has been demonstrated to be a predictor of future cardiovascular events .
