Objective To study the effective surgical methods for the sequela of deep vein thrombosis(DVT) of lower extremity . Methods The clinical data of 32 patients with the sequela of DVT of lower extremity in 36 limbs treated by surgery since 1992 were analysed retrospectively. Results Diagnosis accuracy rate of angiography in sequela of DVT was 100%. There were type I in 5 limbs, type IIA in 4, type IIB in 12,and type III in 15. External constriction valvuloplasty of superficial fomoral vein(SFV) was performed on 16 limbs,valvuloplaasly of SFV on 3 limbs,great saphenous vein popliteal vein anastomosis in situ in 6 limbs,muscular loop plasty on popliteal vein in 4 limbs,common iliac vein SFV anastomosis with artificial vessel interposition in 3 limbs,great saphenoas vien ansatomosed to opposite SFV in 4 limbs. After treatment,symptoms totally disappeared in 28 limbs ( 77.8% ), and improved in 8 limbs. Conclusions The vasography is diagnostic chrysindicatrix of the DVT sequela. Different operations based on the damage of valves should be chosen.

Objective To investigate the clinical efficacy of laparoscopic-assisted linea alba reconstruction for postpartum diastasis recti.Methods The retrospective cross-sectional study was conducted.The clinical data of 14 patients with postpartum diastasis recti who were admitted to Ruijin Hospital of Shanghai Jiaotong University School of Medicine between June 2016 and June 2018 were collected.Patients underwent laparoscopic-assisted linea alba reconstruction.Observation indicators:(1) intra-and post-operative recovery situations;(2) follow-up.Follow-up using outpatient examination and telephone interview was performed to detect postoperative long-term complications,diastasis recti and umbilical hernia recurrence up to September 2018.Measurement data with normal distribution were represented as (x)±s and measurement data with skewed distribution were described as M (P25,P75).Results (1) Intra-and post-operative situations:14 patients underwent successful laparoscopic-assisted linea alba reconstruction and 8 complicated with umbilical hernia area of (6± 3) cm2 were sutured and closed.The mesh area,operation time,visual analogue score for pain at the first day after operation,time of postoperative drainage-tube removal and duration of postoperative hospital stay were respectively (214±26) cm2,(74 ± 14) minutes,3.7 ± 0.6,(3.3 ± 0.7) days and (4.1 ± 1.2) days.No patient required administration of analgesics and had postoperative complication.(2) Follow-up:14 patients were followed up for 17 months (5 months,21 months).During the follow-up,1 patient returned visit at postoperative day 10 due to surgical incision drainage and cured after dressing change.The other patients had no complications,without diastasis recti and umbilical hernia recurrence.Conclusion Laparoscopic-assisted linea alba reconstruction for postpartum diastasis recti is safe and effective.
