ObjectiveTo summarize the effects of endovascular intervention and artificial graft bypass for the occlusive superficial femoral artery disease.
MethodsThe clinical data of 122 patients (136 limbs) with superficial artery occlusive disease underwent endovascular intervention or artificial graft bypass from January 2008 to April 2011 in this hospital were collected retrospectively. Age, TASCⅡgrading, condition of outflow tract, complications before and after procedures, hospital stay, primary patency rate, rate of amputation, and death rate were recorded.
Results①Seventy-four limbs of 64 patients were accepted percutaneous transluminal angioplasty and stent graft (PTA/S group), 62 limbs of 58 patients were accepted femoral popliteal artery artificial graft bypass (artificial graft bypass group). Compared with the artificial graft bypass group, the age was significantly older (P < 0.05), TASCⅡA or B lesions were more (P < 0.05), TASCⅡC or D lesions were less (P < 0.05), the limbs with one or three outflow tracts were more (P < 0.05) in the PTA/S group. The limbs with two outflow tracts, and the patients combined with diabetes or hypertension or diabetes and hypertension had no significant differences between these two groups (P > 0.05).②There was no perioperative mortality in two groups. Compared with the artificial graft bypass group, the average hospital stay was sifnificantly shorter (P < 0.05), the 3-year death rate after procedure was higher (P < 0.05), the rate of postoperative incision infection was lower (P < 0.05), the primary patency rate of 36-month after operation was lower (P < 0.05) in the PTA/S group. The rate of amputation, the primary patency rates of 6-, 12-, and 24-month after operation had no significant differences between these two groups (P > 0.05).
ConclusionsManagement of occlusive superficial femoral artery disease with femoral popliteal artery artificial bypass grafting exhibits a higher long term patency as compared with percutaneous stent graft. However, the hospital stay is longer than that in PTA/S group, and postoperative infection also occurres individually in artificial graft bypass group. Percutaneous transluminal angioplasty and stent graft has little trauma, faster recovery, shorter hospital stay, which is an important significance for the patients with too old or weak to accept femoral popliteal artery artificial graft bypass. But its long term patency rate needs to be improved.
ObjectiveTo evaluate the effect of percutaneous mechanical thrombectomy (PMT) with AngioJet mechanical thrombus aspiration system for the acute deep venous thrombosis (DVT) of lower extremities. MethodsThe clinical data of 72 patients (72 limbs) with acute DVT who underwent PMT with AngioJet system from December 2015 to June 2018 in our hospital were analyzed retrospectively. ResultsOf the 72 cases, 30 cases underwent PMT alone, while 42 cases underwent PMT combined with catheter directed thrombolysis (CDT). Thrombus clearance rate of grade Ⅲ was obtained in 49 cases (68.05%), grade Ⅱ in 20 cases (27.78%), and grade Ⅰ in 3 cases (4.17%). Thirty-five cases were found with May-Thurner syndrome, and 34 cases were treated with stenting while 1 case complicated with iliac bleeding. The rates of PTS were 1.41% (1/71), 3.57% (2/56), 4.55% (2/44), and 20.00% (3/15) at 3-month, 6-month, 1-year, and 2-year after intervention, respectively. The deep vein patency rates were 86.36% (38/44) and 80.00% (12/15) at 1-year and 2-year after intervention, respectively. The iliac stent patency rates were 100% (23/23) and 87.50% (7/8) at 1-year and 2-year after intervention, respectively. ConclusionThe effect of PMT assisted with CDT for the acute DVT of lower extremities is satisfactory, but its long-term efficacy needs to be further observed.
