Abstract Details


To evaluate the renal arteries and abdominal aorta by color Doppler ultrasonography in patients with pseudoexfoliation syndrome


Department of Radiology and Ophthalmology, School of Medicine, Namik Kemal University, Tekirdag, Turkey


This propective case-control study involved 49 patients with pseudoexfoliation (PEX) syndrome and 42 control subjects. Abdominal aorta and renal arteries were examined by color Doppler sonography (Acuson X 300 ultrasound imaging system, siemens, mountain view, CA, USA). In both renal arteries (proximal and distal portions) and abdominal aorta, the peak systolic velocity (PSV) were measured. Measurement of the maximum diameter of the abdominal aorta was recorded. Renal artery stenosis was defined as a renal artery PSV >150 cm/sec or renal-to-aortic ratio (RAR) >3.0. Computed tomographic angiography was performed to confirm these findings in patients with renal artery stenosis.


The mean PSV in the proximal renal artery was 88.3 cm/sec in PEX group and 79.5 cm/sec in control group (P = .314); in distal renal artery was 91.7 cm/sec in PEX group and 93.0 cm/ sec in control group (P = .794); in abdominal aorta was 76.0 cm/sec in PEX group and 65.2 cm/ sec in control group (P = .046). Renal artery stenosis was observed in nine patients with PEX syndrome and in only one patient without PEX syndrome. Four of the patients in PEX group had abdominal aorta aneurysm.


Pseudoexfoliation syndrome may account for renal artery stenosis as a cause of hypertension and abdominal aorta aneurysm. FINANCIAL DISCLOSURE?: No
