“…Ohara and colleagues reported spontaneous resolution of severe BP fluctuation within 2 weeks after the onset, with normalization of plasma catecholamine levels and no uptake of MIBG into the tumor, secondary to completion of the extensive necrosis [11] . Otherwise, particularly when emergent surgery and medical control using alpha-1 blockade bear high risk, treatment might comprise mechanical circulatory support with a cardiopulmonary device or intra-aortic balloon pump and/or removal of catecholamines by continuous hemodiafiltration [28] , [29] , [30] , [31] , [32] . Alternatively, we chose to perform emergent TAE, which swiftly controlled the critical BP fluctuation, and ultimately performed elective surgical tumor resection.…”
