【Abstract】ObjectiveTo evaluate the efficacy of whole body hyperthermia (WBH) in the treatment of advanced hepatic carcinoma and its effect on liver function. MethodsFrom 2001 to 2004, 39 cases of advanced hepatic carcinoma were treated with WBH. The effect of WBH on liver function was assessed by liver function test before and after treatment. Results①The effective rate of WBH was 61.5%（24／39） in the treatment of advanced hepatic carcinoma with declined AFP in 60.0%（9/15） of patient and 100% of patients had pain relieve. The survival rates of 6 months, 1 year and 2 years were 76.9%（30/39）, 59.0%（23/39） and 12.8%（5/39）, respectively. ②Alanine aminotransferase (ALT) elevated obviously in 1-3 d after treatment (Plt;0.05), and then approached to its baseline in 7 d. Aspartate aminotransferase (AST) increased significantly 1 d after treatment (Plt;0.05),and then back to its baseline in 3-7 d. Albumin (ALB) appeared dropped 1 d after treatment (Plt;0.05), and restored normally in 3 d. The levels of total bilirubin (TBIL) and gamma glutamyl transpeptidase (GGT) had no evident significant change with the WBH treatment in abnormal liver function group, but TBIL increased 1-3 d after treatment in normal liver function group (Plt;0.05). ConclusionIn the treatment of advanced hepatic carcinoma, WBH can improve the patients’ life quality and prolong their life expectancy. Meanwhile, it could also result in reversible impairment of liver function.
ObjectiveTo compare the impact of cardiopulmonary coronary artery bypass grafting (CCABG) and off-pump coronary artery bypass grafting (OPCAB) on the incidence of postoperative acute kidney injury (AKI) in the elderly patients (age≥70 years). MethodsThe clinical data of the isolated coronary artery bypass grafting (CABG) patients (age≥70 years) in our center from January 1, 2009 to December 31, 2017 were collected and retrospectively analyzed. The patients with long-term dialysis, missing serum creatinine data, emergent surgery or CABG combined with other cardiac procedures were excluded. Totally there were 3 346 patients undergoing isolated CABG, and finally 1 405 patients (age≥70 years) entered the study. The elderly patients were divided into a CCABG group (956 patients) and an OPCAB group (449 patients) according to whether they used extracorporeal circulation. The incidence and severity of postoperative AKI in the two groups were compared. Results AKI occurred in 306 (32.0%) patients in the CCABG group and in 138 (30.7%) patients in the OPCAB group with no significant difference (P=0.677). According to the acute kidney injury network (AKIN) criteria, the severity of AKI in the CCABG vs. OPCAB was as followings, AKIN stage Ⅰ: 211 (22.1%) vs. 93 (20.7%); AKIN stage Ⅱ: 51 (5.3%) vs. 23 (5.1%); and AKIN stage Ⅲ: 44 (4.6%) vs. 22 (4.9%) with no significant difference (P=0.579, 1.000 and 0.788). There was no significant difference in the new onset of dialysis between the CCABG group (31 patients, 3.2%) and the OPCAB group (10 patients, 2.2%, P=0.376). Conclusion AKI is a common complication in the elderly CABG patients, with AKIN stage Ⅰ accounting for the most proportion, but rate of postoperative renal replacement therapy is low. Compared with CCABG, OPCAB is not associated with a significantly low rate or reduced severity of AKI in elderly patients.
ObjectiveTo explore the experience of surgical repair for congenital aortic stenosis (AS) in our center.MethodsWe retrospectively reviewed the clinical data of 145 children diagnosed with AS, who underwent aortic repair from 2008 to 2019, with or without aortic insufficiency (AI), including 104 males and 41 females with a median age of 2.9 (0.6, 7.8) years. The preoperative and intraoperative data, early and long-term valvular function, long-term survival rate and freedom from reoperation and aortic valve replacment (AVR) were analyzed.ResultsThere were 120 patients receiving commissurotomy, 15 valvuloplasty with extra pericardium patch, and 25 AVR. The mean follow-up time was 0.25-11.20 (4.2±2.8) years. Survival rate at 10 years was 92.3%. Freedom from reoperation and AVR was 63.2% and 60.4% respectively. Multivariate analysis revealed that using a patch during surgery (P=0.036) was an independent risk factor for reoperation. A history of preoperative balloon dilation (P=0.029) and significant preoperative AI (P=0.001) contributed to AVR.ConclusionSurgical treatment of congenital aortic valve stenosis in children is a safe and effective method that provides enough time to achieve a more definitive solution. Using a patch during surgery increases reoperation hazard. A history of previous balloon dilation and significant preoperative AI may result in AVR during the follow-up.
ObjectiveTo discuss outcomes of arch reintervention for post-repair recoarctation in children.MethodsFrom 2009 to 2019, 48 patients underwent reintervention for post-repair recoarctation in Shanghai Children’s Medical Center. Of the 48 patients, 22 patients had surgical repair, 25 patients had balloon angioplasty (BA), and 1 patient had a stent implantation. The clinical data were analyzed, and the difference in time-to-event distribution between the surgical group and the BA group was determined by a log-rank test.ResultsThe median age at reintervention was 15.0 months (range, 3.0 months-15.1 years). The median weight at reintervention was 9.8 kg (range, 3.0-58.0 kg). The time to reintervention after initial repair was 12.5 months (range, 2.0 months-7.8 years). One patient (2.1%) died in hospital and 1 patient (2.1%) experienced arrhythmia after surgical repair. One late mortality (2.1%) occurred after surgical reintervention. One patient (2.1%) experienced aortic dissection after BA. No patient died after BA. Freedom from residual coarctation or new recurrences was 66.7%, 61.3%, and 56.9%, respectively, at 1, 2, and 5 years after reintervention. Freedom from residual coarctation or new recurrences was 90.0%, 81.8%, and 70.1%, respectively, at 1, 2, and 5 years after surgical repair. Freedom from residual coarctation or new recurrences was 52.0%, 48.0%, and 48.0%, respectively, at 1, 2, and 5 years after BA. Compared with BA, surgery-based reintervention had a lower incidence of residual coarctation or recurrences (χ2=4.400, P=0.036).ConclusionReintervention for recoarctation has favorable early outcomes. Compared with balloon angioplasty, surgical repair has a more lasting effect in relieving the recoarctation.
ObjectiveTo explore the effect of LeCompte maneuver on in-hospital mortality and mid-to-long term reintervention after single-stage arterial switch operation in children with side-by-side Taussig-Bing anomaly. Methods Clinical data of patients diagnosed with side-by-side Taussig-Bing anomaly and undergoing single-stage arterial switch operation in Shanghai Children’s Medical Center from 2006 to 2017 were retrospectively analyzed. Patients were divided into two groups based on whether LeCompte maneuver was performed: a LeCompte maneuver group and a non LeCompte maneuver group. The clinical data of two groups were compared. ResultsFinally 92 patients were collected. LeCompte maneuver was performed in 32 out of 92 patients with a median age of 65.0 days and an average weight of 4.3 kg, among whom 24 (75.0%) were male. Fifteen (46.9%) patients received concomitant aortic arch repair while 12 (37.5%) patients were associated with coronary artery malformation. LeCompte maneuver was not performed in 60 patients with a median age of 81.0 days and an average weight of 4.8 kg, among whom 45 (75.0%) were male. Twenty-two (36.7%) patients received concomitant aortic arch repair while 35 (58.3%) patients were associated with coronary artery malformation. The average cardiopulmonary bypass duration of the LeCompte maneuver group showed no statistical difference from the non LeCompte maneuver group (179.0±60.0 min vs. 203.0±74.0 min, P=0.093). The in-hospital mortality of the two groups were 6 (18.8%) and 7 (11.7%), respectively, which also showed no statistical difference (P=0.364). The median follow-up period was 4.1 (1.6, 7.5) years for 79 patients with 8 lost to follow-up, and no death was observed. Kaplan-Meier curve and log-rank test showed no statistical difference in overall mid-to-long term reintervention rate (P=0.850) as well as right ventricular outflow tract and pulmonary artery reintervention rate (P=0.240) with or without LeCompte maneuver. ConclusionWhether or not to perform LeCompte maneuver shows no statistical impact on in-hospital mortality and mid-to-long term reintervention rate of single-stage arterial switch operation for side-by-side Taussig-Bing anomaly.
ObjectiveTo explore growth pattern of neo-aortic root as well as development of neo-aortic regurgitation after arterial switch operation (ASO) for Taussig-Bing anomaly. MethodsFrom 2002 to 2017, the patients who received ASO, and were discharged alive from Shanghai Children’s Medical Center and followed up for more than 3 years were retrospectively involved in this study. ResultsA total of 127 patients were enrolled. There were 98 (77.2%) males, the median age at ASO was 73.0 d and the average weight was 4.7 kg. Forty-five (35.4%) children were complicated with mild or mild-to-moderate pulmonary insufficiency (PI) before ASO. The average follow-up time was 7.0 years. During the follow-up, 14 (11.0%) children presented moderate or greater neo-aortic regurgitation (neo-AR). The diameter of neo-aortic annulus and sinus of Valsalva was beyond normal range during the entire follow-up. The average diameter of neo-aortic annulus was 18.0 mm at 5 years and 20.5 mm at 10 years. The average diameter of sinus of Valsalva was 25.9 mm at 5 years and 31.1 mm at 10 years. Neo-AR continued to develop over time. The diameter of children who developed moderate or greater neo-AR was constantly larger than that of children who did not (χ2=18.3, P<0.001). Preoperative mild or mild-to-moderate PI was an independent risk factor for the development of moderate or greater neo-AR during mid-to-long term follow-up (c-HR=3.46, P=0.03). ConclusionThe diameters of neo-aortic annulus and sinus of Valsalva of Taussig-Bing children who receive ASO repair continue to expand without normalization. The dilation of annulus correlates with the development of neo-AR. PI before ASO repair increases the risk of neo-AR development.
