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 investigate the clinical characteristics and treatment to improve the prognosis of liver abscess after liver transplantation. MethodsEight cases of liver abscess after liver transplantation who were treated in our hospital from Apr. 1999 to Sep. 2013 were retrospectively analyzed, including clinical presentation, predisposing factors, treatment, and prognosis of outcomes. ResultsIn our group, the incidence of liver abscess after liver transplantation was 2.07% (8/387), and main predisposing factors included biliary complications, hepatic artery complications, and so on. The treatments included sensitive antibiotics therapy, reducing or deactivating immunosuppressant, aspiration and drainage of abscess by the ultrasound guiding, balloon valvuloplasty for biliary stenosis, percutaneous transhepatic cholangial drainage (PTCD), indwelling biliary stents, endoscopic nasobiliary drainage (ENBD), and hepatic resection. All of the 8 cases were followed-up for 3-59 months (median of 23 months), during the follow-up period, 4 cases were cured, 1 case improved, and 3 cases died. ConclusionsHepatic arterial and biliary complications are the most common predisposing factors for liver abscess after liver transplantation. Active prevention and treatment of biliary and hepatic arterial complications after liver transplantation are the key to reduce the occurrence of liver abscess and improve the prognosis of it.
