Objective To investigate the therapeutic effect of the meso-cavo-atrial shunt (MCAS) in the treatment of combined Budd-Chiari syndrome (BCS). Methods The clinical data of 17 cases of combined BCS with all or bilateral hepatic vein occlusion and long range occlusion or obstruction of inferior vena cava (IVC) were admitted to the Qilu Hospital from February 2000 to May 2004. All patients were treated by MCAS with artificial blood vessels. The pre- and postoperative clinical symptoms, the IVC and portal venous (PV) pressures, the incidence of postoperative complications and the patency rate of the artificial vessels were analyzed. The survival of patients was analyzed using the Kaplan-Meier analysis, and the data were analyzed using the chi-square test and t test. Results No patient died during the perioperative period, and the symptoms of 15 patients disappeared or were relieved after operation, with a significant difference compared with those before operation (χ2 =9.78, P <0. 05 ). Three patients had complications after the operation. The postoperative PV and IVC pressures were decreased by 1.2 cm H2O (1 cm H2O =0.098 kPa) and 18.5 cm H2O, respectively. There were significant differences in the decrease of IVC and PV pressures ( t = 2.38, 3.06, P < 0.05 ). The 1-, 3-, 5-year survival rates were 16/17, 15/17 and 14/17, respectively, and the 5-year patency rate of the artificial vessels was 14/17.Conclusions MCAS can simultaneously relieve IVC and PV hypertension for patients with combined BCS. The postoperative complication rate was decreased, the 5-year survival rate and the patency rate of the artificial vessels were improved after the treatment, so MCAS is an optional surgical method for treating combined BCS.

Objective To summarize clinical experience of one-station therapy for infected seriouslyischemic diabetic foot.Methods The clinical data of 15 patients (15 diseased limbs in total) with infected seriously-ischemic diabetic foot,who were admitted to authors' hospital during the period from June 2015 to April 2016 to receive treatment,were retrospectively analyzed.For all patients,one-station sequential therapy was carried out,which included endovascular revascularization (EVR) to open occluded vessel,surgical debridement and closed negative pressure wound drainage and antiseptic moisturizing wound dressing.The healing rate of infected wound and the limb salvage rate were evaluated.Results The 15 patients included 10 males and 5 females,with a median age of 77 years old.Lower extremity angiography showed that multiple segmental lesions of lower limb were detected in 13 patients and simple leg lesions in 2 patients.According to TASC Ⅱ update classification,leg artery disease of grade D was observed in 13 patients and artery disease of grade C in 2 patients.After EVR therapy,at least one branch of leg arteries was reopened in 14 limbs.Intact arterial arch of pedal-plantar loop (PPL) was seen in 6 patients,semi-arterial arch in 7 patients,and absent of arterial arch in 2 patients.After surgical debridement,the wound was washed by using negative pressure wound therapy (NPWT) device as well as serf-made washing equipment.The time to control wound infection was (7.85±2.84) days.After discharge,the patients were followed up every 3-4 days,at the same time wound dressing exchange with antibacterial moisturizing sulfadiazine silver lipid hydrogel was conducted.Wound healing was achieved in 12 patients,and the mean healing time was (3.70±0.87) months.The wound failed to heal in 3 patients,among them below knee amputation had to be performed in 2 patients (13.3%,both patients showed absent of arterial arch of PPL),and the remaining one patient died of cardiovascular event.Statistically significant difference in PPL pathological changes existed between wound healing group and wound un-healing group (P=0.006 7).Conclusion The treatment of infected seriouslyischemic diabetic foot is rather complicated.Being one-station therapy,the sequential managements,which include EVR,NPWT device together with washing equipment and use of antibacterial moisturizing wound dressing,can effectively increase the blood supply to the affected limb,shorten the time to control infection and lower amputation rate.Therefore,one-station therapy should be regarded as the preferred method for infected seriously-ischemic diabetic foot.
