ABSTRACT
Objective To compare the clinical efficacy of transdorsal-to-plantar (TDP) or transplantar-to-dorsal (TPD) retrograde endovascular angioplasty in treating below-the-knee arterial occlusion diseases, and to compare it with conventional anterograde endovascular angioplasty. Methods A total of 96 patients with below-the-knee arterial occlusion diseases (112 diseased lower extremities in total), who were admitted to authors’ hospital during the period from Oct. 2009 to July 2011 to receive conventional anterograde endovascular angioplasty, were enrolled in this study. The clinical data were retrospectively analyzed. Among the 112 diseased lower extremities, conventional anterograde endovascular angioplasty failed in 27, and TDP or TPD retrograde endovascular angioplasty had to be carried out. A total of 71 patients (85 diseased lower limbs) were successfully treated with conventional anterograde endovascular angioplasty (routine group), while 20 patients (22 diseased lower limbs) were successfully treated with retrograde endovascular angioplasty (retrograde group). The preoperative ankle-brachial index(ABI), the coronary angiography-based thrombolysis in myocardial infarction (TIMI) flow score, the dorsal or plantar arterial pulse score, the postoperative limb salvage rate and target vessel patency rate were calculated, and the results were compared between the two groups. Results The technical success rate in the retrograde group and the routine group was 75.9% and 74.0%respectively (P>0.05). Preoperative ABI value of the retrograde group and the routine group was 0.55± 0.21 and 0.56±0.14 respectively, after the treatment which increased to 0.93±0.19 and 0.89±0.18 respectively (P>0.05). Preoperative TIMI score of the retrograde group and the routine group was 0.1 ±0.5 and 0.8 ±0.8 respectively, which significantly increased to 2.5±0.6 and 1.8±0.8 respectively (P0.05). Twenty-four months after endovascular angioplasty Kaplan-Meier analysis indicated that the limb salvage rate of the retrograde group and the routine group was 95.5%and 96.5%respectively (P>0.05). Conclusion Compared with conventional anterograde endovascular angioplasty for the treatment of below-the-knee arterial occlusion diseases, retrograde endovascular angioplasty via TDP or TPD path can immediately improve the blood flow with obvious improvement of ABI score, primary target vessel patency rate as well as the limb salvage rate. Therefore, retrograde endovascular angioplasty should be regarded as an effective supplementary technique when anterograde angioplasty fails.
