A New Scoring System for the Prediction of Wound Healing After Endovascular Treatment in Critical Limb Ischemia: Wound Healing Prediction Score (WHPS)

Abstract

Background: Since a popliteal artery is located at the joint site, there is a possibility of stent fracture. As there is also a possiblity of vascular anastomosis when bypassing, the area is referred as non-stenting zone. Furthermore, Asians frequently sit with their knees bent deeply, and there is not much evidence. Here, we have evaluated the clinical results of 18 months of endovascular treatment for popliteal artery. Methods: A non-randomized, retrospective study was adopted at our hospital. Endovascular treatment was performed on 132 limbs (106 patients) with popliteal arteries from April 2007 until December2011. The age range was 72.5 10 years, including 84 limbs (63.6%) exhibiting critical limb ischemia. Artery patency was evaluated via angiography or vascular ultrasound. Have examined the technical success, primary patency, secondary patency.(follow up term 18.4 months) Results: 125 limbs (94.6%) were successful procedures, and stents were used for the 16 limbs (12.1%). The primary patency rate was 76% and secondary patency rete was 95%. Exacerbation of ischemia due to the procedure has not been observed. Conclusion: The results of endovascular treatment in the area of endovascular popliteal artery for the 12 months were within the acceptable range.
