摘 要:目的分析亚临床嗜铬细胞瘤(PHEO)的临床特点。方法回顾性总结并分析北京协和医院1997年-2007年收治的22例亚临床PHEO的病例资料。结果患者均无明显临床症状,测定24hN儿茶酚胺正常10例,增高12例。16例患者用仅受体阻滞剂进行术前准备,手术中切瘤前挤压瘤体患者血压升高的最高值、切瘤后血压下降的最低值及术中血压波动分别为(163±34)/(86±20)mmHg、(105±12)/(61±10)mmHg及(58±37)/(25±21)mmHg;而6例未用药物准备的患者上述指标分别为(169±36)/(104±20)mmHg、(97±18)/(56±13)mmHg及(71±48)/(48±29)mmHg,术前用药准备组的切瘤前DBP最高值和术中DBP波动值比未用药准备组均明显减少(均P〈0.05)。结论大部分亚临床PHEO患者尿儿茶酚胺升高,并且术中血压波动较大,对患者用仪受体阻滞剂进行术前准备非常必要,可以减少手术风险。Objective To analyze the clinical features of patients with subclinical pheochromocytoma (PHEO). Methods Review of clinical features of 22 patients with subclinical PHEO treated in PUMC hospital from 1997 to 2007. Results All patients were asymptomatic. 24hr-urinary catecholamine excretion was detected normal in 10 of 22 cases, while increased in the others. Sixteen patients were prepared with a-receptor blocker before operation.During the operation, BPmax (maximal blood pressure) before tumor resection, BPmin (minimal blood pressure) after resection and △BP(BPmax-BPmin) were ( 163 ± 34)/(86 ± 20)mmHg, ( 105 ± 12)/(61 ± 10) mmHg and ( 58 _± 37 ) / ( 25 ± 21 ) mmHg, Respectively, in the prepared group. They were ( 169 ± 36 ) / ( 104 ± 20) mmHg, ( 97 ± 18)/(56 ± 13)mmHg and (71 ± 48 )/(48 ± 29)mmHg in the other 6 cases without a-blocker preparation.DBPmax and ADBP in the prepared group were significantly lower than the unprepared group. Conclusion Most patients with subclinical PHEO have increased catecholamine secretion. Blood pressure is fluctuant greatly during operation in some patients . Patients should be treated with α - receptor blocker preoperatively in order to decrease the operation risk.
