This study retrospectively analyzed the risk factors and outcomes of patients undergoing repeat pulmonary thromboendarterectomy and compared them with those undergoing the first surgery. The results showed that patients in the repeat surgery group were younger, more likely to have a hypercoagulable state, and had higher preoperative right atrial pressure. Despite an increased risk of postoperative complications, repeat pulmonary thromboendarterectomy surgery can still achieve significant hemodynamic improvement in experienced centers.
Objective: Chronic thromboembolic pulmonary hypertension is potentially curable via pulmonary thromboendarterectomy. A minority of patients experience recurrence of their symptoms and are eligible for repeat pulmonary thromboendarterectomy. However, little data exist regarding risk factors and outcomes for this patient population. Methods: We performed a retrospective review of the University of California San Diego chronic thromboembolic pulmonary hypertension quality improvement database, including all patients who underwent pulmonary thromboendarterec-tomy from December 2005 to December 2020. Of the 2019 cases performed during this period, 46 were repeat pulmonary thromboendarterectomy procedures. Demographics, preoperative and postoperative hemodynamics, and surgical complications were compared between the repeat pulmonary thromboendarterectomy group and 1008 first pulmonary thromboendarterectomy group. Results: Repeat pulmonary thromboendarterectomy recipients were more likely to be younger, to have an identified hypercoagulable state, and to have higher preoperative right atrial pressure. Etiologies of recurrent disease include incomplete initial endarterectomy, discontinuation of anticoagulation (noncompliance or for medical reasons), and anticoagulation treatment failure. Patients who received repeat pulmonary thromboendarterectomy had significant hemodynamic improvement, but less pronounced compared with patients who received first pulmonary thromboendarterectomy. Repeat pulmonary thromboendarterectomy was associated with an increased risk of postoperative bleeding, reperfusion lung injury, residual pulmonary hypertension, and increased ventilator, intensive care unit, and hospital days. However, hospital mortality was similar between the groups (2.2% vs 1.9%). Conclusions: This is the largest reported series of repeat pulmonary thromboendarterectomy surgery. Despite an increase in postoperative complications, this study demonstrates that repeat pulmonary thromboendarterectomy surgery can result in significant hemodynamic improvement with acceptable surgical mortality in an experienced center.
