This is a retrospective observational cohort study involving patients with suspected PPGLs who underwent 131I-MIBG scanning and surgical treatment between January 2020 and April 2023. The objective is to evaluate the correlation between MIBG imaging score and intraoperative hemodynamic fluctuations.

Difference of SBP ARV and MAP ARV in Different Groups
Mean arterial pressure (MAP) was calculated with the formula: MAP=1/3\*SBP+2/3\*DBP. ARV, which was defined as the average of absolute difference between successive BP values
Time frame: Intraoperative systolic blood pressure (SBP) and diastolic blood pressure (DBP) were recorded automatically in a 5 min interval from the beginning to the end of surgery.
