Abstract:
Objective To discuss the therapeutic efficacy of bidirectional subintimal angioplasty in the treatment of atherosclerotic occlusive of lower limbs.Methods Five patients with long segment of obstructed artery in lower limb were enrolled in the study.Of five patients,occlusion of the lower segment of abdominal aorta and bilateral iliac artery was seen in one,occlusion of iliac artery in 2 and occlusion of superficial femoral artery in the remaining two.Antegrade subintimal angioplasty procedure was unsuccessful in all five patients as the wire could not be placed into the true lumen,so retrograde subintimal angioplasty by puncturing the distal segment of the occlusive artery was employed.Through the newly created channel the retrograde guide wire was manipulated to be pulled out of vessel through the antegrade catheter.The subintimal tract was dilated with angioplasty balloon and the stent implantation was performed.Results Bidirectional subintimal angioplasty was successfully accomplished in all five patients,with a total of nine stents being implanted.Conclusion Bidirectional subintimal angioplasty is a safe and effective procedure for bringing the subintimal recanalization to success,this technique can be regarded as a remedial measure when unidirectional subintimal angioplasty ends up in failure.
