| Objective : To investigate the effect of PPL encapsulation technology on inferior knee atherosclerotic occlusive disease and its postoperative changesMethods:Prospective analysis of patients undergoing CT vascular reconstruction(computed tomographic arteriography,CTA)at????Hospital from March 2018 to December 2018,who were clearly diagnosed with inferior knee arteriosclerosis occlusive disease,with clinical symptoms such as resting pain,Intermittent claudication,ulcers,Fontaine classification,Rutherford classification,under the guidance of the Angiosome concept,concurrently performed percutaneous transluminal angioplasty(PTA)combined(Pedal-plantar Loop,PPL)surgery.According to the characteristics of specific symptoms,technical success rate,clinical success rate,preoperative and postoperative clinical symptom scores,comparative analysis of preoperative and postoperative ABI,the opening of different lesions with stenosis or occlusion,postoperative patency rate,and limb salvage rate Analyze and explore the symptoms of surgery.The results were statistically analyzed,and statistical analysis was performed using SPSS 21.0 statistical software.P<0.05 was considered statistically significant.Results : In this group of 66 patients(66 limbs),66 patients(66 limbs),with an average age of 68.53 ± 7.18 years,severe claudication 15.15%,resting pain 16.67%,mild ulcers 45.45%,severe ulcers or gangrene 22.72%,66 patients had 198 stenosis and(Or)occlusion.The technical success rate was 89.40% and the clinical success rate was 90.90%.The preoperative symptom score was 5.68 ± 1.49,2 weeks after operation was 1.14 ± 0.94,1 month after operation was 1.13 ± 0.91,6 months after operation was 1.05 ± 0.96,and 12 months after operation was 1.05 ± 0.93,P < 0.05,the difference was different.Statistical significance.The preoperative ABI average was 0.45 ± 0.07,and the postoperative 2 weeks was 1.06 ± 0.06,and the difference was statistically significant compared with the preoperative ABI value(P <O.O5).The average ABI at 2 weeks after surgery was 1.06 ± 0.06,ABI was 1.09 ± 0.06 at 1 month after surgery,1.10 ± 0.07 at 6 months after surgery,and 1.14 ± 0.07 at 12 months after surgery,which was significantly different from that before It has statistical significance(P <0.05).Comparing stenosis and occlusion,the former has a higher opening rate than the latter,and the difference is statistically significant.Multiple linear regression analysis of the efficacy showed that patients with lower symptom scores,shorter durations,lower total cholesterol,and shorter smoking history had better outcomes.The patency rate of 2 weeks after operation was 96.76%,the patency rate of 2nd stage was 96.76%,and the limb salvage rate was 100%.The patency rate of the first stage in January was 89.39%,the patency rate of the second stage was 89.39%,and the limb salvage rate was 100%.In June,the patency rate of the first phase was 83.33%,the patency rate of the second phase was 84.85%,and the limb salvage rate was 95.45%.In December,the patency rate of the first phase was 74.24%,the patency rate of the second phase was 80.30%,and the limb salvage rate was 84.85%.Complication analysis showed that the operation was safe and feasible.Conclusion :1.PPL opening technology is a feasible,safe,minimally invasive and less complication treatment for inferior knee arteriosclerosis occlusive disease.2.PPL opening technology is effective in the treatment of inferior knee arteriosclerotic occlusive disease,but long-term arterial patency needs further observation and research.3.Stenosis is easier to open than occlusive disease.Therefore,PPL should be performed early to avoid development of occlusive disease. |
