PS96. Screening for Carotid & Renal Stenosis in Patients Undergoing Tesio Catheter Placement

An earlier report demonstrated that if the prevalence of significant carotid disease to be greater than 4.5%, screening may be cost-effective. Many factors associated with carotid artherosclerosis are shared with those of chronic renal disease, and those patients who have severe renal artery disease may eventually require Tesio catheter placement. Therefore, we postulate performing carotid/renal duplex scans in this high-risk population may be of benefit. Between July 2005 and August 2009, 641 patients underwent tesio catheter placement. Of these, 136 patients underwent carotid duplexes perioperatively. 13 patients (9.6%) had≥60% stenosis, 8 patients (5.9%) had 70-99% stenosis, and 5 patients (3.7%) had prior CEA procedure, each mutually exclusive. Sex was not a significant factor in the outcome of the carotid duplex scans. Of the 109 patients who underwent renal artery duplex, renal artery stenosis was noted in 4.9% of the patients and 2 AAA's were noted. Our results indicates a significant prevalence of carotid and renal artery stenosis for patients who will also receive Tesio catheter placement, espescially for those with history of coronary artery disease and >60 years of age.Tabled 1> 60 %50-70%70-99%s/p CEAno DM10.9%18.8%6.3%1.6%DM8.3%22.2%5.6%5.6%no CAD3.4%8.6%3.4%0CAD14.1%29.5%7.7%6.4%p value.042.0028.467.071no HTN020%010%HTN8.7%30.2%6.3%3.2%DM & CAD12.5%30%7.5%10%<60 y.o.07.1%0061-80 y.o.13.2%27.9%5.9%2.9%>81 y.o.10%17.5%10%7.5% Open table in a new tab
