Abstract

Objective Surgery is the primary strategy for treating phaeochromocytoma (PCC), but it can lead to severe hypertension and heart failure. Although valsartan is effective in reducing high blood pressure, clinical data on the potential role of valsartan in PCC are currently limited. Therefore, the aim of this study was to investigate the effects of pretreatment with terazosin and valsartan on patients with PCC.

Methods In this retrospective cohort study, 50 patients who underwent laparoscopic resection of PCC were enrolled. During preoperative preparation, the patients (n=25) in the control group were treated with terazosin, while those (n=25) in the combination treatment group were treated with terazosin and valsartan. The levels of catecholamine hormones before and after surgery were determined, and the intraoperative blood pressure and the incidence of complications were compared between the two groups.

Results The results showed no significant differences in baseline patient characteristics or surgical conditions between the two groups (p>0.05). However, on the third day after surgery, the levels of catecholamine hormones in the two groups were significantly lower than those before surgery (p<0.05), while the levels in the combination treatment group were notably lower than those in the control group (p<0.05). The patients in the combination treatment group showed lower intraoperative blood pressure fluctuations and incidence of perioperative complications compared with the control group (p<0.05).

Conclusions Terazosin combined with valsartan can effectively improve perioperative haemodynamic instability and reduce postoperative complications in the preoperative management of PCC.
