ObjectiveTo compare mid-to long-term outcomes of selective coronary venous bypass grafting (SCVBG) using internal mammary artery (IMA) grafts and great saphenous vein (GSV) grafts for surgical treatment of diffuse right coronary artery atherosclerosis. MethodsWe retrospectively analyzed clinical data of 75 patients undergoing SCVBG in Beijing Anzhen Hospital from January 2003 to December 2012. GSV was used as grafts for SCVBG in 54 patients (GSV group), and IMA was used as grafts for SCVBG in 21 patients (IMA group). All the patients were followed up in November 2013. Their survival condition, recent relapse rate of angina, recent echocardiographic results and coronary CT angiography (CTA) were analyzed. ResultsOverall survival rate of IMA group was slightly higher than that of GSV group (100.0% vs. 83.3%), but survival curves showed no statistical difference in survival rate between the 2 groups (P=0.055). Coronary CTA showed significant blockage in GSV grafts and middle cardiac vein in patients in GSV group (n=39), while IMA grafts and middle cardiac vein in patients in IMA group (n=18) were mostly visible and patent (P < 0.001). Left ventricular ejection fraction (LVEF) of the 2 groups were significantly higher than preoperative values, but there was no statistical difference between the 2 groups. ConclusionCompared with SCVBG using GSV, SCVBG using IMA can significantly improve mid-to long-term patency of the grafts and middle cardiac vein, and is an efficacious procedure for diffuse right coronary artery atherosclerosis.
Objective To evaluate long-term outcomes of surgical closure of atrial septal defect (ASD) and combined surgical radiofrequency ablation for atrial fibrillation (AF). Methods A total of consecutive 15 patients with ASD undergoing surgical closure of ASD and combined surgical radiofrequency ablation in our department between March 2003 and April 2015. There were 7 males and 8 females at an average age of 47.1±10.8 years ranging from 16 to 62 years. Retrospective analysis and follow-up were performed to evaluate long-term success rate freedom from AF after surgery. Results All patients recovered and discharged, and no patient suffered death or stroke. The duration of follow-up was from 3 to 136 months for all patients. Success rate freedom from AF at 1, 3, 5 and 10 years was 81.3%, 75.0%, 68.8% and 61.1%, respectively. During follow-up, there was no death or stroke. One patient required permanent pacemaker implantation. Conclusion Concomitant surgical closure of ASD and biatrial radiofrequency ablation is safe and effetive with better long-term outcomes. It is necessary to perform the two procedures together for ASD patients.
Objective To compare long-term outcomes following mitral valvuloplasty (MVP) and mitral valve replacement (MVR) for native valve endocarditis (NVE). Methods Between November 1993 and August 2016, consecutive 101 patients with NVE underwent mitral surgery in our department, MVP for 52 patients and MVR for 49 patients. There were 69 males and 32 females at age of 38.1±14.9 years. The mean follow-up was 99.4±75.8 months. Results There was no statistical difference in cardiopulmonary bypass time, aortic cross-clamp time, in-hospital mortality, duration of mechanical ventilation, ICU stay or hospital stay after surgery between the two groups. Survival rate at 1, 5, 10, 20 years after surgery was 100.0%, 97.6%, 97.6%, 97.6% for MVP, and 93.5%, 84.3%, 84.3%, 66.2% for MVR with a statistical difference between the two groups (P=0.018). There was no stroke in the patients with MVP during follow-up periods. However, stroke-free survival rate at 1, 5, 10, 20 years after surgery was 100.0%, 93.9%, 89.4%, 70.2% for MVR patients with a statistical difference between the two groups (P=0.023). There was no statistical difference in recurrence of infection, perivalvular leakage and reoperation between the two groups. Composite endpoint-free survival rate at 1, 5, 10, 20 years after surgery was 100.0%, 97.6%, 92.9%, 92.9% for MVP, and 91.3%, 79.6%, 75.8%, 51.0% for MVR with a statistical difference (P=0.006). Conclusion MVP is associated with better outcomes than MVR in the patients with NVE; generalizing MVP technique in the patients with NVE is needed.
ObjectiveTo explore our novel strategy of surgical treatment for ventricular septal rupture (VSR) and the long-term outcomes.MethodsAll the patients referred to the Center of Adult Surgery, Fuwai Hospital were treated with integration treatment of vasoactive agents, intra-aortic balloon pump, or left ventricular assist device. The timing of surgical treatment was individually customized. One hundred and five consecutive patients with VSR (63 males, 42 females ) presented at the mean age of 63 (range, 41 to 80) years. We retrospectively analyzed the results and followed up patients who survived the surgical procedure.Results They were divided into a hemodynamics stable group (25 patients, 2 received emergent operation and 23 received selective operation) and a hemodynamics unstable group (80 patients, 34 received vasoactive agents and selective operation, 4 received vasoactive agents and emergent operation, 20 received vasoactive agent, intra-aortic balloon counterpulsation (IABP), and selective operation, 16 received vasoactive agents, IABP, and emergent operation, 2 received vasoactive agents, IABP, ventilator support, and selective operation, 2 received vasoactive agents, IABP, and ventilator support and emergent operation, 2 received vasoactive agents, ventilator support, and selective operation). There were 3 in-hospital deaths. Ninety-nine patients were followed up, with a follow-up rate of 97.1%. The mean follow-up time was 76.56±47.78 months. There were 2 late deaths during follow-up.ConclusionThe timing of surgical treatment for ventricular septal rupture should be individually customized. The long-term outcomes of ventricular septal rupture patients who survived the surgery are satisfactory.
ObjectiveBased on the latest version of the Database from Colorectal Cancer(DACCA), this study analyzed the long-term effect of neoadjuvant therapy combined with intersphincteric resection (ISR) in patients with rectal cancer. MethodsAccording to the established screening criteria, clinical data of 944 patients with rectal cancer admitted from January 2009 to December 2020 were collected from the DACCA updated on March 21, 2022, to explore the influencing factors for overall survival (OS) and disease specific survival (DSS) of rectal cancer treated with neoadjuvant therapy combined with ISR, by Cox proportional hazard regression model. Results① The 3-year OS and DSS survival rates of neoadjuvant therapy combined with ISR for rectal cancer were 89.2% and 90.4%, respectively, and the 5-year OS and DSS survival rates were 83.9% and 85.4%, respectively. ② For different ISR surgical methods and neoadjuvant therapy plans, there were no significant differences in OS and DSS (P>0.05), but there were significant differences in OS and DSS among different ypTNM stage groups (P<0.001), patients with ypTNM 0–Ⅱ had better OS and DSS. ③ BMI, ypTNM stage and R0 resection were influencing factors for OS and DSS (P<0.05). ④ The overall incidence of postoperative complications was low, including 6.4% (60/944) within 30 days, 7.5% (71/944) within half a year and 3.3% (31/944) over half a year after operation. ConclusionsIn the comprehensive treatment of patients with low/ultra-low rectal cancer, neoadjuvant therapy combined with ISR can achieve relatively stable and good long-term oncological efficacy, and the incidence of short-term postoperative complications is not high, which is one of the options.
Objective To summarize the experience with median sternotomy ascending-descending thoracic aortic bypass grafting via median sternotomy for the treatment of complex coarctation of aorta (COA), and to present the intermediate to long-term follow-up outcomes. Methods A retrospective analysis was performed on patients with complex COA who underwent ascending-descending thoracic aortic bypass grafting through a median sternotomy in the First Hospital of Tsinghua University from August 2004 to May 2017. ResultsA total of 7 children were enrolled, including 4 males and 3 females, with an average age of (13.3±4.6) years and an average weight of (40.2±12.2) kg. Six (85.7%) patients had hypertension in the upper limbs. Among them four patients had coarctation associated with intracardiac anomalies, two with recurrent coarctation post-surgery, and one with both recurrent coarctation and intracardiac anomalies. All surgeries were performed under cardiopulmonary bypass, with no operative mortality or severe complications. The systolic pressure gradient between the upper and lower extremities decreased significantly from preoperative (51.4±13.5) mm Hg to postoperative (2.9±2.7) mm Hg (P<0.01). During a follow-up period of (14.9±5.9) years (ranging from 7 to 19 years), there were no late deaths or graft-related complications. Except for one patient who continued to have mild hypertension, the blood pressure of all other patients returned to normal. Conclusion The ascending-descending thoracic aortic bypass grafting via median sternotomy for complex COA is a safe and reliable procedure that effectively reduces upper limb blood pressure and the pressure difference between the upper and lower extremities. It has a low rate of complications and satisfactory intermediate to long-term outcomes.
