ABSTRACT
BACKGROUND:
Surgical manipulation of pheochromocytomas and paragangliomas (PPGLs) may induce large hemodynamic oscillations due to catecholamine release. Little is known regarding hemodynamic instability during percutaneous ablation of PPGLs. We examined intraprocedural hemodynamic variability and postoperative complications related to percutaneous ablation of extra-adrenal metastases of PPGL.METHODS:
From institutional PPGL registry we identified patients undergoing ablation of extra-adrenal PPGL metastases from January 1, 2000, through December 31, 2016. We reviewed medical records for clinical characteristics and hospital outcomes. Tumors were categorized as functional or nonfunctional based on preprocedural fractionated catecholamine and metanephrine profiles.RESULTS:
Twenty-one patients (14 female [67%]) underwent 38 ablations. Twenty-four ablations were performed in patients with functional metastatic lesions, and 14 were in nonfunctional lesions. Intraprocedural use of potent vasodilators for hypertension was higher for patients with functional tumors (P = 0.02); use of vasopressors for hypotension was similar for functional and nonfunctional tumors (P = 0.74). Mean (±SD) intraprocedural blood pressure range (maximum-minimum blood pressure) during 38 procedures was greater for functional than nonfunctional tumors [systolic 106 (±48) vs 64 (±30) mm Hg, P = 0.005; diastolic 58 (±22) vs 35 (±14) mm Hg, P = 0.002; mean arterial 84 (±43) vs 47 (±29) mm Hg, P = 0.007]. Complications included 5 unplanned intensive care unit admissions (3 for precautionary monitoring, 1 for recalcitrant hypotension, and 1 for hypertensive crisis), 1 case of postoperative bleeding, and 1 death.CONCLUSIONS:
Substantial hemodynamic instability may develop during ablation of functional and nonfunctional PPGL metastases. When anesthesia is provided for ablation of metastatic PPGLs in radiology suites, preparation for hemodynamic management should match standards used for surgical resection.Key words
