Effect of a One-session Versus Two-session Procedure on Different Parameters of Interventional Therapy for Peripheral Arterial Occlusive Disease: Results of a Retrospective Cohort Study
Received 16 May 2009; received in revised form 24 November 2009; accepted 18 December 2009. published online 26 February 2010.
Purpose
To compare the effects of a one-session procedure (ie, diagnostic angiography immediately followed by intervention) versus a two-session procedure (ie, diagnostic angiography and intervention in two separate sessions) on interventional therapy in patients with peripheral arterial occlusive disease (PAOD).
Materials and Methods
Interventional therapy was performed immediately after diagnostic angiography in one session in 228 patients (group 1) and in a chronologically separate, later session in another 43 patients (group 2). The retrospectively captured parameters were Fontaine stage, TransAtlantic InterSociety Consensus II criteria, angiographic severity, type, technical success and complication rates, examination times, volume of contrast media, radiation exposure, and fluoroscopy time for intervention.
Results
There were no between-group differences in clinical and interventional parameters. In group 1 there were 340 interventions performed, and there were 61 in group 2 with an interval before intervention of 1–55 days. The groups showed comparable success rates (92.6% vs 91.8%; P = .79) and complication rates (5.7% vs 4.65%; P = 1.0). The examination times were similar at 82.6 minutes ± 40.5 and 91.3 minutes ± 69.9, respectively (P = .92). Volume of contrast media (301.7 mL ± 81.3 vs 459.2 mL ± 123.7) and radiation exposure (140.5 Gy/cm2 ± 152.1 vs 304.7 Gy/cm2 ± 217.4) were significantly lower in group 1 (P < .001 each). Fluoroscopy times trended lower in group 1.
Conclusions
In patients with PAOD, interventional therapy of iliac and femoropopliteal artery lesions performed in the same session as diagnostic angiography yields technical success and complication rates comparable to those seen with a two-session procedure, but is associated with significantly less contrast media use and radiation exposure.
