Experience with pulmonary endarterectomy: Lessons learned across 17 years

Background Pulmonary endarterectomy is potential curative therapy for chronic thromboembolic pulmonary hypertension patients. Here, we present our experience with pulmonary endarterectomy spanning 17 years and detail our management strategy. Methods This is a single-centre retrospective study conducted on chronic thromboembolic pulmonary hypertension patients who underwent pulmonary endarterectomy at our centre across 17 years. Results Between 2004 and 2020, 591 patients underwent pulmonary endarterectomy. Amongst them 429 (72.4%) were males with a male to female ratio of 2.6:1, the median age was 38 (range, 14–73) years. The median length of hospital stay was 11 days (IQR, 8–16). Extra corporeal membranous oxygenation was used in 82 (13.9%) patients during/after surgery, out of whom 28 (34.1%) survived. There were 70 (11.8%) in-hospital deaths. Female gender (p 100 mmHg (p
