Abstract
The effects of pheochromocytomas and paragangliomas (PPGLs)-induced catecholamine overproduction on vascular and cardiac function are generally thought to be reversible after PPGLs removal. However, a sizable proportion of patients who were free of the recurrent disease still faced high risks of cardiovascular problems after successful surgery. We aim to identify incidence and risk factors for long-term cardiovascular complications in PPGLs patients after surgery. We retrospectively reviewed 602 patients who underwent surgery for sporadic PPGLs at three centers between January 2012 and October 2022. Demographic characteristics and perioperative data were recorded. Multiple logistic regression was used to determine the risk factors for postoperative long-term cardiovascular complications. Finally, a total of 602 patients were included in the analysis, comprising 460 (76.4%) patients with pheochromocytomas and 142 (23.6%) patients with paragangliomas. After a median follow-up of 64 months, 76 (12.6%) patients had developed long-term cardiovascular complications. Independent risk factors included pheochromocytomas (odds ratio [OR] = 4.13, 95% confidence interval [CI]: 1.425-11.965, p = 0.009), had low preoperative left ventricular ejection fraction (LVEF, OR = 5.659, 95% CI: 2.141-14.955, p < 0.001), experienced intraoperative hemodynamic instability (HDI, OR = 2.498, 95% CI: 1.423-4.385, p = 0.001), suffered from postoperative in-hospital cardiovascular complications (OR = 5.723, 95% CI: 2.078-15.758, p = 0.001) and long-term persistent hypertension (OR = 3.552, 95% CI: 1.580-7.988, p = 0.002). Long-term cardiovascular complications commonly occur in patients with surgical-cured PPGLs. Pheochromocytomas, had low preoperative LVEF, experienced intraoperative HDI, suffered from postoperative in-hospital cardiovascular complications, and persistent hypertension were determined as the risk factors for long-term cardiovascular complications. These findings may help to improve follow-up management.
