Abstract
MotivationTo describe clinical experience of a series of cases of adult patients with chronic thromboembolic pulmonary hypertension who underwent pulmonary thromboendarterectomy. MethodsDescriptive retrospective study of eight adults who underwent pulmonary thromboendarterectomy at the Fundación Cardiovascular de Colombia between February 2010 and April 2013. Results5 women and 3 men were assessed, with an average age of 45±18 years, with avergae baseline data of SpO2 92±2%, PaO2/FiO2 244±82, PaCO2 28.8±3.4mmHg, average pukmonary pressure of 53±11mmHg and pulmonary vascular resistance (PVR) of 999±414dyn/s/cm−5. On the third postoperative day one patient required veno-arterial extracorporeal membrane oxygenation (ECMO) during 11 days. At 4±1 days after pulmonary thromboendarterectomy, PVR decreased 71±21% with regards to baseline value (p=0.002, IC 95%) and pulmonary pressure was reduced to 32±27mmHg (p=0.001). Baseline SpO2 increased 96±3%. Survival rate was 100% after 24 months of follow-up, without readmissions or recurrence of pulmonary thromboembolism. ConclusionsInstitutional results were adequate in the short and medium term. Cases with reperfusion edema, the alternative of ECMO as an extracorporeal life support is imperative.
