MiscellaneousRelation of Baseline Renal Dysfunction With Outcomes in Patients Undergoing Popliteal and Infrapopliteal Percutaneous Peripheral Arterial Interventions
Section snippets
Methods
For the present study, we used data from patients in the Laser in Infra-popliteal and Popliteal Stenosis (LIPS) study. The details of this study have been previously published.8 In brief, LIPS was a retrospective study examining angiographic and short-term clinical outcomes of patients receiving percutaneous PVI for popliteal and infrapopliteal stenosis.8 All patients received either laser-assisted balloon angioplasty or balloon angioplasty alone. Data for LIPS were collected through
Results
Patients in the CKD group were older, whereas those on dialysis were younger compared with subjects with normal renal function (Table 1). Blacks accounted for significantly higher proportion of patients in the dialysis group. The prevalence of co-morbid conditions was higher in the CKD and dialysis groups. A history of previous limb amputation was fourfold greater in the dialysis group compared with the normal renal function group.
Postprocedural residual stenosis and procedural success were
Discussion
Our study suggested that in patients undergoing PVI, those with baseline renal dysfunction had worse long-term mortality and morbidities compared with those with normal renal function. Co-morbid conditions were greater in patients with CKD and dialysis. Nonetheless, adjusted long-term mortality remained significantly higher in CKD and worst in the dialysis group, suggesting that these factors were independently associated with worse outcomes. Similarly, baseline angiographic features were worse
