Objectives:
To propose an original approach based on simultaneous dual vascular access site (DAS) using 2 small-size guiding catheters to easily perform complex 2-stent techniques for bifurcation coronary lesions (BL).
Background:
Simultaneous kissing stenting and classic crush technique require large 7 or 8Fr guiding catheters leading to large amounts of contrast medium, vascular access site complications, and sometimes frictions or criss-cross of the 2-stent delivery systems.
Methods:
DAS was used in 30 patients with BL (11 radio-radial, 16 radio-femoral, and 3 femoro-femoral). Among 60 guiding catheters, the size was 5Fr in 28, 6Fr in 30, and 7Fr in 2 cases of double adjacent BL. When 2 different size catheters were used, contrast medium injections were done using the smallest size catheter. DAS patients were compared with a group of 30 BL patients treated using a single femoral vascular access site (SAS) with 7 or 8Fr catheters.
Results:
Success rate was 100% in all patients. Contrast volume used was smaller in DAS than in SAS patients (277 ± 156 cc vs. 380 ± 165 cc,P = 0.01). No vascular access site complication occurred in the sub-group of the 11 DAS radio-radial patients. Postintervention hospitalization duration was shorter in DAS than in SAS (1.9 ± 2 vs. 2.8 ± 2 days,P = 0.048).
Conclusion:
DAS allows to successfully perform complex stenting technique of BL using small-size guiding catheters leading to decreased contrast medium volume, decreased vascular access site complications rates, and shortened hospitalization duration.
