ABSTRACT
Heart transplantation is the primary therapeutic option for patients with end-stage heart failure. The shortage of donors has been the main limiting factor for the increasing quantity of heart transplantation. With persistent updating and introduction of novel technologies, the donor pool has been increasingly expanded, such as using the heart from older donors, donors infected with hepatitis C virus, donors dying from drug overdose or donation after cardiac death (DCD) donors, etc. Meantime, the proportion of recipients with advanced age, multiple organ dysfunction, mechanical circulatory support and human leukocyte antigen antibody sensitization has been significantly increased in recent years. The shortage of donors, complication of recipients' conditions, individualized management of immunosuppressive therapy and prevention and treatment of long-term cardiac allograft vasculopathy are all challenges in the field of heart transplantation. In this article, novel progresses on donor pool expansion, improving the quality of recipients, strengthening the diagnosis and treatment of rejection, and preventing cardiac allograft vasculopathy were reviewed, aiming to prolong the survival and enhance the quality of life of patients with end-stage heart failure on the waiting list or underwent heart transplantation.
ABSTRACT
Objective To investigate the risk factors of central airway stenosis after lung transplantation. Methods Clinical data of 155 recipients undergoing lung transplantation in Wuxi People's Hospital Affiliated to Nanjing Medical University from July 2016 to December 2017 were retrospectively analyzed. According to the incidence of central airway stenosis following lung transplantation, all recipients were divided into the stenosis group (n=36) and control group (n=119). The incidence of central airway stenosis after lung transplantation was summarized. The risk factors of central airway stenosis after lung transplantation were assessed by univariate and multivariate logistic regression analyses. Results Among 155 lung transplant recipients, 36 cases (23.2%) developed central airway stenosis. The average incidence time was (53±13) d after lung transplantation. Univariate analysis demonstrated that bilateral lung transplantation, grade 3 primary graft dysfunction (PGD), airway fungal infection, long cold ischemia time, long mechanical ventilation time and long intensive care unit (ICU) stay were the risk factors for central airway stenosis after lung transplantation (all P < 0.05). Multivariate analysis showed that airway fungal infection, long cold ischemia time and long mechanical ventilation time were the independent risk factors for central airway stenosis after lung transplantation (all P < 0.05). Conclusions Airway fungal infection after lung transplantation, long cold ischemia time and long mechanical ventilation time probably lead to central airway stenosis after lung transplantation. Active preventive measures and intimate monitoring should be taken to improve the quality of life of the recipients after lung transplantation.
ABSTRACT
Lung transplantation is the ultimate treatment for many kinds of end-stage lung diseases. However, the perioperative management of lung transplantation is complicated with high fatality of patients. Extracorporeal membrane oxygenation (ECMO) is an effective method of extracorporeal respiration and circulation support. ECMO plays an important role in the perioperative support treatment of lung transplantation, which breaks the limitation of contraindications and promotes the development of lung transplantation. In this article, the indications, catheter placement strategies and application of ECMO in the perioperative period of lung transplantation were reviewed.
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.
