Objective To investigate methods and results of endovascular treatment in TASC (Ⅱ) D-type femoral artery occlusion. Methods From January 2012 to May 2013, 26 cases (26 branches) of superficial femoral artery occlusion with endovascular treatment of TASC (Ⅱ) D-type superficial femoral artery occlusion were retrospectively reviewed. The effi-cacy was evaluated through ABI, CTA, DSA and symptoms improved. Results 26 branches were treated with endovascular methods. Technical success rate was 80.7%(21/26), including 13 branche with stent implantation, 6 branches with Silver-hawk atherectomy and 2 branches with Viabahn stent implantation. All patients were followed up for a mean period of (10.3 ± 1.2)months, primary patency rates at 6 months were 69.2%in stent group, 66.7%in Silverhawk atherectomy group and 100%in Viabahn stent group. Conclusion Endovascular treatment of TASC (Ⅱ) D-type femoral artery occlusion can lead to satisfactory short term patency rates, and Viabahn stent is the latest treatment.

Objective:To explore the clinical efficacy of posterior femoral muscle flaps combined with posterior femoral cutaneous nerve nutrient vessel flap and closed lavage in the treatment of stage Ⅳ ischial tuberosity pressure ulcers.Methods:This study was a retrospective observational study. From March 2021 to March 2022, 15 patients with stage Ⅳ ischial tuberosity pressure ulcers who met the inclusion criteria were admitted to Dezhou Dongcheng Hospital, including 11 males and 4 females, aged 31 to 72 years. The pressure ulcer wound size ranged from 6.0 cm×4.5 cm to 10.0 cm×6.0 cm, with cavity diameters of 10-14 cm. Five cases were complicated with ischial tuberosity bone infection. After clearing the lesion, the biceps femoris long head muscle flap with an area of 10.0 cm×4.0 cm-18.0 cm×5.0 cm and the semitendinosus muscle flap with an area of 8.0 cm×4.0 cm-15.0 cm×5.0 cm combined with the posterior femoral cutaneous nerve nutrient vessel flap with an area of 6.5 cm×5.5 cm-10.5 cm×6.5 cm was transplanted to repair the pressure ulcer wound. The flap donor area was directly sutured, and the closed lavage with tubes inserted into the wound cavity was performed for 2-3 weeks. The postoperative survival of the muscle flaps and skin flaps, the wound healing of the donor and recipient areas were observed. The recurrence of pressure ulcers, the appearance and texture of flaps, and scar conditions of the donor and recipient areas were followed up.Results:All the muscle flaps and skin flaps in the 15 patients successfully survived after surgery. Two patients experienced incisional dehiscence at one week after surgery due to improper turning over, during which the incision in the recipient area was pressed on, and the wounds healed after dressing changes of 3 to 4 weeks; the wounds in the donor and recipient areas healed well in the other patients. All patients received follow-up after surgery. During the follow-up period of 6 to 12 months, none of the patients experienced pressure ulcer recurrence, and the texture, color, and thickness of the skin flaps closely resembled those of the surrounding skin at the recipient site, with only linear scar left in the donor and recipient areas.Conclusions:When using the posterior femoral muscle flaps combined with the posterior femoral cutaneous nerve nutrient vessel flap and closed lavage to treat stage Ⅳ ischial tuberosity pressure ulcers, the tissue flap can be used to fully fill in the dead space of the pressure ulcers. After treatment, the wound heals well, the appearance of the donor and recipient areas is better, and the pressure ulcers are less prone to reoccur.

Objective To analyze the application of serological test results in the diagnosis and treatment of anti-M-in-duced hemolytic disease of the fetus and newborn(HDFN),and to explore HDFN prevention strategies.Methods The se-rological test results of 12 cases of HDFN caused by anti-M diagnosed in our laboratory from January 2017 to December 2023 were retrospectively analyzed,including blood group identification of mothers and children,serum total bilirubin/hemoglo-bin/antibody titer test,and three hemolysis tests in newborns.Clinical data of the children and mothers were collected,in-cluding pregnancy history,blood transfusion history,prenatal antibody testing,history of intrauterine blood transfusion and gestational week of delivery,and the prognosis of the children was followed up.Results All 12 cases of fetal neonatal he-molytic disease due to anti-M were RhD+MN phenotype newborn born to RhD+NN mother,with maternal-fetal incompati-blility in MN blood groups.In the ABO blood group system,ABO incompatibility between mother and child accounted for 41.7%(5/12).None of the mothers had a history of blood transfusion,and the median titer of the test at 4℃was 32,and the median titer at 37℃was 4.The mothers of 3 cases had a history of multiple intrauterine blood transfusions,with an inci-dence of 25%(3/12).One case had an abnormal first pregnancy,with an incidence of 8.3%(1/12),and seven cases had an abnormal pregnancy with a miscarriage,with an incidence of abnormal pregnancy and birth history of 58.3%(7/12).There were 6 cases of premature labor,with an incidence of 50%(6/12).The mothers in three cases underwent regular ob-stetric examination and the specificity of the antibodies was determined,accounting for 25%(3/12).Twelve children had free antibodies with a median titer of 6 at 4℃and 2 at 37℃.Two children had anti-M antibodies that were not reactive at 37℃,with a negative rate of 16.7%(2/12).The positive rate of DAT and elution test was respectively 8.3%(1/12)and 16.7%(2/12)in the children.The median minimum hemoglobin value was 75 g/L,and all 12 children received blood transfusions.The median peak total bilirubin value was 157.5 μmol/L,and none of them reached the threshold for blood ex-change.The rate of delayed anemia was16.7%(2/12),the postnatal mortality rate was8.3%(1/12),and 11 children was free of growth and neurodevelopmental delay in prognosis.Conclusion Anti-M can cause severe HDFN,which can also oc-cur in primigravida.The intensity of antibody titer does not correlate with the severity of the disease,and it is prone to cause delayed anemia,which should be monitored regularly according to the serological characteristics of anti-M and clinical symp-toms,and should be treated timely.

OBJECTIVETo evaluate the safety and efficacy of the perineal rectosigmoidectomy (Altemeier procedure) in the treatment of full thickness rectal prolapse.

METHODSClinical and follow-up data of 52 patients with full thickness rectal prolapse undergoing Altemeier procedure in 9 hospitals from September 2010 to July 2016 were analyzed retrospectively. Of which 38 cases were from Zhongnan Hospital of Wuhan University, 1 case from Suizhou Central Hospital of Hubei province, 1 case from Jingzhou Second People's Hospital of Hubei province, 3 cases from Wuxue First People's Hospital of Hubei province, 1 case from Jingmen First People's Hospital of Hubei province, 1 case from Tuanfeng County Hospital of Hubei province, 4 cases from Jingzhou Central Hospital of Hubei province, 2 from PLA Rocket Army General Hospital, 1 case from the Affiliated Hospital of Xuzhou Medical University in Jiangsu province. Altemeier operation steps: The line shaped teeth, the prolapsed rectum is first exposed to the anus. In the dentate line proximal 1-3 cm with ultrasonic knife or Ligasure ring outer rectal incision, using electric knife to mark pre resection line in rectal mucosa. Open down in front of the pelvic peritoneum. Incision of the outer intestine and the reduction of the internal rectum and part of sigmoid colon. To free and remove excess pelvic retroperitoneal, pelvic peritoneum and be at the top of the colon or rectum anterior pelvic reconstruction suture. The rear of the levator ani muscle forming rectum. Pull gently to the anus and rectum and sigmoid, in the absence of tension, 2-3 cm outside the anus was selected as the proximal inner bowel pre resection line, along the line of pre transection of proximal bowel resection, again the broken end of intestine full-thickness end-to-end anastomosis. Postoperative complication and recurrence were summarized. Gastrointestinal quality of life index (GIQLI), Wexner constipation score and Wexner fecal incontinence score were used to evaluate the efficacy.

RESULTSAll the 52 patients were beyond moderate full thickness rectal prolapse. Thirty-one were male and 21 were female with age ranging from 22 to 83 (average 53) years. The length of prolapsed rectum was 6 to 20 (average 9) cm and course of disease was 0.5 to 46(average 19.5) years. No perioperative death. Five patients (9.6%) had postoperative complications, including 2 anastomotic bleeding, 1 wall portion dehiscence of anastomosis, 1 anastomotic stenosis, and 1 malnutrition. Recurrence rate was 9.6%(5/52) within the long-term follow-up of 5 to 71 (median 40) years. Compared with the preoperative results, Wexner constipation score and Wexner fecal incontinence score decreased obviously (2.1±1.4 vs. 4.6±3.4, 4.8±4.1 vs. 6.8±4.1), and GIQLI significantly increased from 99.6±8.0 to 103.0±9.1 (all P<0.05) at 6-month after operation. Above 3 scores were sustained and continuously improved at 12-, 24-, and 36-month during the follow-up (all P<0.05).

CONCLUSIONAltemeier procedure possesses good efficacy with low morbidity of complication and recurrence in the treatment of full thickness rectal prolapse.
