FIGUEREDO MORENO, Antonio et al. Three-year impact of experience with pulmonary thromboendarterectomy. Rev. Colomb. Cardiol. [online]. 2016, vol.23, n.4, pp.305-312. ISSN 0120-5633.  https://doi.org/10.1016/j.rccar.2015.11.006.

Motivation: To describe clinical experience of a series of cases of adult patients with chronic thromboembolic pulmonary hypertension who underwent pulmonary thromboendarterectomy. Methods: Descriptive retrospective study of eight adults who underwent pulmonary thromboendarterectomy at the Fundación Cardiovascular de Colombia between February 2010 and April 2013. Results:5 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 ± 3.4 mmHg, average pukmonary pressure of 53 ± 11 mmHg and pulmonary vascular resistance (PVR) of 999 ± 414 dyn/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 ± 27 mmHg (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. Conclusions: Institutional results were adequate in the short and medium term. Cases with reperfusion edema, the alternative of ECMO as an extracorporeal life support is imperative.
