AI Article Synopsis
- The study analyzed 792 lung transplant surgeries to evaluate surgical complications and their effects on mortality and survival.
- Out of 769 patients reviewed, 32% experienced complications, leading to a significant increase in 30-day mortality rates among those patients.
- Key factors influencing complications included the type of transplant, patient age, and the necessity for extracorporeal support, which contributed to poorer long-term survival outcomes.
Article Abstract
Objective: To assess the incidence of surgical complications after lung transplantation and its influence on early mortality and long-term survival.
Methods: Retrospective review of 792 lung transplants (LTs) performed from 1994 to 2022. Among them, 769 with complete data were selected. Patients with and without surgical complications were compared by univariable and multivariable analyses.
Results: There were 385 single LTs (50%), 371 double LTs (48%), 8 bilobar LTs (1%), and 5 combined liver LTs (1%). Two hundred forty-nine patients presented surgical complications (32%) as follows: bronchial (n = 61), vascular (n = 55), pneumothorax (n = 33), and phrenic nerve palsy (n = 22). Thirty-day mortality (noncomplicated vs complicated) was 57 (41%) vs 80 (59%), P < .001. Transplants for bronchiectasis (58%), pulmonary hypertension (50%), and re-transplants (78%) presented more surgical complications (P < .001). Double LT (40%), bilobar LT (88%), and combined liver LT (100%) presented more surgical complications (P < .001). Complicated recipients were younger (49 ± 15 vs 45 ± 17 years; P = .001), with longer ischemic times (429 ± 67 vs 450 ± 76 min [2nd graft]; P = .007), and required extracorporeal support (ECLS) more often (43% vs 57%; P < .001). Survival at 1, 5, 10, 15, and 20 years (noncomplicated vs complicated): 78%, 63%, 52%, 41%, 31% vs 52%, 42%, 35%, 26%, 22%; P < .001). Predictors of mortality were the need for ECLS (odds ratio [OR] 4.14; P < .001), postoperative ventilation (hours) (OR 1.01; P < .001), and vascular complications (OR 4.78; P < .001).
Conclusion: Surgical complications remain an important source of morbidity and mortality after lung transplantation. Complex surgical procedures requiring ECLS develop frequent surgical complications needing long postoperative ventilation that are associated with early mortality and poorer long-term survival.
