Objective To compare Vecchietti′s and Davydov′s laparoscopic techniques for vagino-plasty in patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. Methods From January 2010 to December 2013, 13 patients underwent the Vecchietti′s laparoscopic procedure (Vecchietti group), and 15 patients underwent the Davydov′s laparoscopic procedure (Davydov group). Intraoperative parameters and postoperative results were compared. Results Both of the two groups were successfully treated. The neovagina in both groups were wide with good elasticity, softness and smoothness. The operation time [(39± 7) versus (73 ± 11) minutes], the intraoperative blood loss [(21 ± 6) versus (63 ± 10) ml], the anal exsufflation time after surgery [(19 ± 5) versus (28 ± 6) hours] and the recovery period of body temperature after surgery [(35 ± 10) versus (46 ± 10) hours] of the Vecchietti group were less than those of the Davydov group (all P<0.05). But the neovagina length [(8.8±0.5) versus (9.6±0.5) cm] was shorter and the Female Sexual Function Index scale score [26.8 ± 2.0 versus 28.5 ± 1.7] was lower in the Vecchietti group than those in the Davydov group (all P<0.05). The postoperation hospital duration didn′t reached statistical difference between the two groups [(7.5 ± 0.9) versus (7.1 ± 0.7) days, P>0.05]. No intraoperative complication occurred. After surgery, 2 patients were found vaginal polyps and 8 patients were suffered from pain in the Davydov group, while all patients were suffered from pain in the Vecchietti group. Conclusions Both Vecchietti′s and Davydov′s laparoscopic techniques are simple, safe and effective surgical methods for vaginal reconstruction. In contrast, the Vecchietti′s procedure is more time efficient and minimally invasive, while the Davydov′s procedure can get less pain, longer vagina and higher sexual satisfaction.

Objective:To study on the association between vasoactive-inotropic score(VIS) and mortality of total arch replacement in Stanford type A aortic dissection(TAAD) patients.Methods:Data of TAAD patients admitted from January 2018 to November 2018 were analyzed retrospectively. According to the inclusion and exclusion criteria, 187 patients were finally included in the analysis. 30-day mortality was calculated and the patients were divided into death group(18 cases) and non-death group(169 cases). The VIS at each time point and perioperative indexes of the two groups were compared. The value of VIS in predicting mortality was analyzed.Results:The 30-day mortality was 9.63%(18/187). The operation time, cardiopulmonary bypass time, ventilator assistance time, the incidence of tracheotomy and major postoperative complications in the death group were significantly higher than those in the non-death group( P<0.05). VIS of death group was significantly higher than that of non-death group( P<0.05). At each time point, the area under ROC curve(AUC) of VIS was greater than 0.500( P<0.05), among which AUC of ICU 48 h VIS was the largest(0.817), and the best cut-off point of ICU 48 h VIS was determined to be 9, sensitivity 61.1%, specificity 92.3%. Logistic regression analysis showed that ICU 48 h VIS was an independent risk factor for predicting the death of total arch replacement in TAAD patients( OR=1.465, 95% CI: 1.194-1.796, P<0.001). Conclusion:When ICU 48 h VIS≥9, the risk of death was increased in patients with total arch replacement of TAAD. VIS may be a useful reference index for predicting the mortality of total arch replacement in TAAD patients in the early postoperative period.

Objective:To compare the early and mid-term results of hybrid coronary revascularization (HCR) and minimally invasive multivessel coronary artery bypass grafting (MICS-CABG) in coronary artery disease patients with low left ventricular ejection fraction and non diabetes mellitus, and to explore the indication of HCR and MICS-CABG.Methods:A retrospective cohort analysis of HCR and MICS-CABG cases with preoperative left ventricular ejection fraction less than 0.40, and without diabetes mellitus were conducted in Xijing Hospital from January 2015 to December 2019. 36 cases in HCR group and 17 cases in MICS group were included in this study. For HCR procedure, minimally invasive left internal mammary artery(LIMA) to the left anterior descending artery (LAD) bypass surgery were performed, and followed by percutaneous coronary intervention (PCI) to treat non LAD lesion 1 to 4 weeks later. MICS-CABG procedure was performed through left anterior small thoracotomy minimally invasive direct coronary artery bypass grafting for multiple diseased vessels.Results:The preoperative SYNTAX score in MICS group was significantly higher than that in HCR group ( P<0.05). There was no perioperative death in both groups. Troponin I, postoperative drainage volume, blood transfusion volume and ventilator ventilation time in MICS group were significantly higher than those in HCR group ( P<0.05). After 12 months follow-up, no patient died in both groups. Furthermore, all LIMA grafts were patency. The stenosis rate of drug-eluting stents in HCR group was similar to that of great saphenous vein grafts in MICS group. LVEF and left ventricular end diastolic diameter of both groups were significantly improved 12 months after operation ( P<0.05). Conclusion:HCR and MICS-CABG are minimally invasive and safe treatment for multivessel coronary artery disease patients with low ejection fraction and non diabetese mellitus. The early and mid-term therapeutic effects are satisfactory. If coronary artery lesions other than LAD are suitable for PCI, HCR should be the preferred treatment.

Objective    To discuss the diagnosis and treatment of culture-negative aortic infective endocarditis. Methods    The clinical data of 73 patients with infective endocarditis of the aortic valve whose results of bacteria culture were negative from January 2013 to January 2018 were retrospectively analyzed, including 59 males and 14 females aged 14-71 (39.2±14.8) years. Results    Sixty seven (91.8%) patients received aortic valve replacement, 2 (2.7%) patients received the second operation in hospital, and 12 (16.4%) patients had concomitant mitral valvuloplasty. In-hospital death occurred in 8 (11.0%) patients. Postoperatively, 11 (20.7%) patients had a low cardiac output and 4 (11.0%) patients had heart block, and 1 patient required implantation of a permanent pacemaker. The 1- and 5- year survival rates were 92.3%±2.3% and 84.5%±4.5%, respectively. Conclusion    There are difficulties in the diagnosis and treatment of culture-negative infective endocarditis. Most of the affected patients are in a healed status, which could be a cause of negative culture results. In-hospital mortality in the patients is associated with a history of previous cardiac surgery, whereas the long-term survival rate is good for the patients after surgery.

Objective    To investigate the therapeutic effect, safety and effectiveness of multiple valvular surgery through right anterolateral intercostal thoracotomy, as well as the mid-term follow-up results and surgeon's learning curve. Methods    The clinical data of 154 patients with multiple valvular disease were performed minimally invasive cardiac surgery in the Department of Cardiovascular Surgery, The First Affiliated Hospital of Air Force Medical University, from 2015 to 2019 were retrospectively analyzed. There were 103 males and 51 females, aged 23-68 years. Closed cardiopulmonary bypass was established through femoral artery and femoral vein, and the thoracic cavity was entered through a 6 cm transverse incision in the fourth intercostal space on the right side of sternum. Baseline and perioperative characteristics and postoperative outcomes were reviewed. Results    There was no perioperative death. The average cardiopulmonary bypass time was 159.3±39.4 min, and the aortic clamping time was 102.3±20.3 min. One patient underwent thoracotomy during the operation, and two patients underwent second thoracotomy for hemostasis. During the follow-up period of 10-55 months, 1 patient died, 2 patients developed mild perivalvular regurgitation, 6 patients developed moderate tricuspid regurgitation, and no serious cardiovascular events occurred in the rest of the patients. Conclusion    Our findings demonstrate that multiple valvular surgery through right anterolateral intercostal thoracotomy is safe, and in an acceptable risk of complication. The early and middle follow-up results are satisfactory. The minimally invasive cardiac surgery can also meet the requirements of cosmetology, and is conducive to the recovery of patients' mental and physical health. This method is worthy of application in medical centers with rich experience in routine cardiac surgery.
