ABSTRACT

Surgical technique of lung transplantation exerts significant impact on clinical prognosis of the recipients. Choosing an appropriate surgical incision determines the exposure of intraoperative visual field, which is the first step of surgical success and directly affects subsequent surgical procedures. Lung transplantation incision is usually considered as primary closure. Nevertheless, for patients with high-risk factors such as oversized lung allografts and primary graft failure after lung transplantation, primary closure cannot be achieved. Hence, delayed chest closure is an effective strategy. The selection of incisions and the adoption of delayed chest closure of lung transplantation exert profound impact upon perioperative prognosis, long-term quality of life and surgical complications of the recipients. Therefore, the development and research status of Clamshell incision, anterolateral incision, posterolateral incision and median sternal incision in lung transplantation were reviewed, highlighting the effect of incision patterns on clinical prognosis of lung transplantation and providing reference for the selection of incisions in clinical lung transplantation.

ABSTRACT

The current organ allocation rules prioritize elderly and urgent patients on the lung transplantation (LT) waiting list. A steady increase in the threshold at which age is taken into consideration for LT has been observed. This retrospective cohort study recruited 166 lung transplant recipients aged ≽ 65 years between January 2016 and October 2020 in the largest LT center in China. In the cohort, subgroups of patients aged 65-70 years (111 recipients, group 65-70) and ≽ 70 years (55 recipients, group ≽ 70) were included. Group D restrictive lung disease was the main indication of a lung transplant in recipients over 65 years. A significantly higher percentage of coronary artery stenosis was observed in the group ≽ 70 (30.9% vs. 14.4% in group 65-70, P = 0.014). ECMO bridging to LT was performed in 5.4% (group 65-70) and 7.3% (group ≽ 70) of patients. Kaplan-Meier estimates showed that recipients with cardiac abnormalities had a significantly increased risk of mortality. After adjusting for potential confounders, cardiac abnormality was shown to be independently associated with the increased risk of post-LT mortality (HR 6.37, P = 0.0060). Our result showed that LT can be performed in candidates with an advanced age and can provide life-extending benefits.

ABSTRACT

Objective To explore the efficacy and prognosis of lung transplantation from donors combined with pulmonary contusion on the treatment of patients with end-stage lung disease. Methods Clinical data of 73 cases of donors and recipients were collected. The donors and recipients were divided into contusion group (23 cases of donors and recipients, with a maximum diameter of contusion in 5-8 cm) and standard group (50 cases of donors and recipients) depending on combined pulmonary contusion. Major clinical indicators [postoperative oxygenation index, duration of mechanical ventilation and chest tube drainage and incidence of primary graft dysfunction (PGD)] and prognosis of the recipients in both groups were compared. Results The recipients in both groups presented no significant difference in postoperative oxygenation index, duration of mechanical ventilation and chest tube drainage and incidence of PGD (all P>0.05). The postoperative 1-year survival of the recipients in standard group and contusion group was 74% and 83%, which presented no statistically significant difference (P>0.05). Conclusions The efficacy and prognosis of lung transplantation from donors combined with pulmonary contusion (with a maximum diameter of 5-8 cm) are comparable to those of lung transplantation from standard donors.

ABSTRACT

Objective To study the influence of pulmonary artery hypertension (PAH) on survival of patients with advanced chronic obstructive pulmonary disease (COPD) on the waiting list of lung transplantation.Methods The characteristics of 143 patients with COPD receiving lung transplantation evaluation from January 2014 to August 2016 were queried.Mild PAH was defined as mean pulmonary artery pressure (mPAP) ≥25 mmHg and severe ≥35 mrnHg by right heart catheterization measurements.The incidence of PAH was studied,and the patients were divided to different groups to determine the effect of PAH on survival prior to transplantation on the basis of different definitions of PAH.Kaplan Meier method was used to draw survival curves,and a log-rank test was used to analyze the effect of PAH on survival of COPD patients on the waiting list of pulmonary transplantation.Univariate and multivariate Cox proportional hazard models were performed to test the relationship between each main covariate and the hazard of mortality.The waiting time was tracked from wait list entry date until death or censoring,and the censoring issues were as follows:receiving lung transplantation,removing from the waiting list without transplant,and still wating for donor until the last follow-up day (2016-08-30).Results Of 143 COPD patients,there were 119 males and 24 males,with mean age of 61.73 years old;46 patients received lung transplantation,and the remaining 97 not;50 had mPAP ≥25 mmHg and 21 had mPAP ≥35 mmHg.A total of 23 cases (22.88%) died on the waiting list.Thirty-eight patients were removed from the list prior to transplantation,and 36 were still on the waiting list.Kaplan-Meier survival function showed suvival of patients with mild PAH or severe PAH was significantly shorter than that of patients without PAH (P<0.001).Using Cox proportional hazards models,univariate analysis revealed significant differences in survival for mild PAH (HR =2.147,95%CI 1.429-3.157,P< 0.001) and severe PAH (HR =3.458,95 % CI 2.518-4.859,P<0.001).Multivariate Cox models identified significant risk for death for mild PAH (HR=2.518,95%CI 1.728-3.364,P<0.001) and severePAH HR=4.027,95% CI 3.257-4.703,P<0.001).Conclusion The incidence of PAH among COPD patients waiting for lung transplantation was high.PAH is associated with significantly increased risk of death among COPD patients waiting for lung transplantation.

ABSTRACT

Objective To investigate the institution of extracorporeal membrane oxygenation(ECMO) for primary graft dysfunction( PGD) after lung transplantation and analysis its clinical outcome. Methods From September 2002 to December 2013, 286 patients with end-stage lung disease underwent lung transplantation(LTx) in Wuxi People's Hospital. Among them, there were 22 patients occured grade 3 PGD in early stage after LTx. In which there were 2 cases with chronic obstructive pulmonary disease, 12 with idiopathic pulmonary fibrosis, 4 case with primary pulmonary hypertension, 1 case with lung tuber-culosis, 1 case with silicosis, 2 cases with bronchiectasis. There were 7 patients with single LTx(3 cases with ECMO support) and 15 patients with bilateral LTx(2 cases with CPB support and 6 cases with ECMO support). According to the severity levels of PGD, different treatment measures were used, such as reinforce ventilatory support, negative fluid balance, extending the treatment time of the ventilator, the use of pulmonary vasodilators, such as prostaglandin E1 and ECMO. Results Six patients were treated by adjusting low volume, high frequency and high positive end expiratory pressure ventilation( PEEP) mode, and 2 cases reversed, 4 cases died of respiratory failure. 16 cases accepted ECMO support, among them 10 cases apply venous-ve-nous mode, 6 cases venous-artery mode, the average flow time was 5. 5 days. 10 cases dismantled from ECMO successly and 6 cases died of multiple organ failure, infection and cardiac arrest. 30-day, 1-year and 5-year survival of PGD recipients post-op-eratively were 55%, 40%, 25%, respectively. Conclusion The high incidence of PGD causes high mortality peri-operative-ly after LTx. Preventing PGD can improve the survival rate of the lung transplant patients. Once PGD happens, appropriate treatment should be given as soon as possible. ECMO can effectively promote the transplanted lung function recovery, reduce the perioperative mortality. If the indications of ECMO use was reached, the institution of ECMO should as soon as possible.

ABSTRACT

ObjectiveTo evaluate the security and effectiveness of raffinose-low potassium dextran solution (RLPDs) for donor lung preservation.MethodsFrom Sep.2002 to Dec.2011,131patients underwent lung transplantation in our institution,including 81cases of single lung transplantation and 50 cases of bilateral lung transplantation.There were 95 males and 36 females.A total of 129 donors were used for organ harvest.Two donors denoted their lungs to four patients receiving single lung transplantation. All the donors were flushed, perfused antegradely and retrogradely,and preserved with hypothermal RLPDs.The repeated reperfusion was necessary when the cold ischemic time was fairly long and the function of donor was poor.During operation,the blood gas analysis,mean pulmonary artery pressure (mPAP) and breathing mechanics were monitored.Postoperatively,all the recipients received re-examination of cardiac ultrasonography,pulmonary function,blood gas analysis and chest imaging.ResultsAll lung transplantations were performed successfully,with a mean cold ischemic time of (193±21) min (range,65-630 min).There was a significant relationship between postoperative pneumonedema and donor lung cold ischernic time (P<0.05),which was also observed between postoperative pneumonedema and primary graft dysfunction (P<0.01). The blood gas analysis and oxygenation index were significantly improved postoperatively,with the mPAP and parameters of breathing mechanics being descended to a normal level.There were 24 early deaths in the first month post-transplant,with a mortality of 18.3% (24/131),including 11cases of sepsis,7 cases of primary graft dysfunction,3 cases of heart failure,1case of bronchial stomal leak,1case of acute rejection,and 1case of pulmonary infarction.The pulmonary function was improved significantly 3 months postoperatively.Conclusion RLPDs is efficient in the preservation of donor lung,with the ability to alleviate ischemic reperfusion injury and improve pulmonary function.

ABSTRACT

Objective To explore the perioperative application of extracorporeal membrane oxygenation (ECMO) in lung transplantation. Methods Thirty patients with primary and end-stage pulmonary disease accompanied by pulmonary hypertension were subjected to operation under the accessory of ECMO. Eighteen patients received single-lung transplantation and 12 patients bilateral sequential lung transplantation without sternal division in our hospital from November 2005 to July 2009. In 2 patients ECMO was given before operation and maintained for 19 days and 6 days respectively. In the remaining patients, ECMO pipeline was placed after anesthesia. After lung trarnsplantation,ECMO was removed after the recipients' oxygen saturation and hemodynamics were stable. Results In all recipients lung transplantation was successfully done. ECOM was removed in 27recipients after operation, and the rest 3 recipients were supported by ECMO after operation: the ECMO was removed at 36th h and 7th day after lung transplantation in two patients respectively,and another one was supported by ECMO for 5 days after operation and suffered acute kidney failure, and died of multiple organ failure 2 weeks post-transplantation. Two recipients were infected in thigh arteriovenous cut and one suffered femoral artery thrombosis, but all of them got better and discharged from hospital after treatment. Conclusion ECMO can be used for lung transplantation on patients with primary and secondary pulmonary hypertension. The complications may be associated with patients'serious condition and unstable hemodynamics. Early detection and active and effective treatment can improve patient's prognosis.

ABSTRACT

Objective To evaluate the effects of ambroxol on prevention of bronchopulmonary complications after thoracotomy in patients with chronic obstructive pulmonary disease(COPD).MethodsTotal 161 elderly patients aged ≥70 years with COPD undergoing thoracotomy were randomly allocated to two groups:ambroxol group (300 mg/d,6 d) and placebo group as control.Pulmonary complications were evaluated by clinical symptoms,radiographic changes,and blood gas analysis. Results The incidence rates of atelectasis were 8.6% in ambroxol group and 28.8% in placebo group,respectively.The PaO2 values after surgery in ambroxol group decreased more than in placebo group (P<0.05) compared with the preoperative values.Side effects were not found in all patients.Conclusions Ambroxol should be considered as an alternative pharmacologic approach for the prevention of post-thoracotomy pulmonary complications in the elderly patients with COPD.
