摘　　要：目的 探讨超声引导下热消融治疗继发性甲状旁腺功能亢进症术后严重低钙血症的危险因素。资料与方法 采用回顾性病例对照研究,选取2019年5月—2023年5月玉林市第一人民医院91例尿毒症合并继发性甲状旁腺功能亢进症患者,均行超声引导下热消融术,根据术后血钙水平,分为严重低钙血症组与非严重低钙血症组。比较两组临床资料差异,采用多因素Logistic回归分析探讨严重低钙血症的独立危险因素。结果 91例患者中,实施微波消融49例,射频消融42例,共消融317个腺体,术后发生严重低钙血症57例(62.64%)。两组术前全段甲状旁腺激素(iPTH)、iPTH 1 d下降率、术前血清碱性磷酸酶、甲状旁腺腺体≥4个比例和腺体总体积差异有统计学意义(P均<0.05)。对iPTH 1 d下降率使用受试者工作特征曲线分析获取最佳截点为74.59%,曲线下面积为0.866(95%CI 0.787~0.945,P<0.05),敏感度为84.2%,特异度为78.1%。多因素Logistic回归分析显示术前血清碱性磷酸酶(OR=1.015,95%CI 1.005~1.025,P=0.030)、iPTH 1 d下降率≥74.59%(OR=30.423,95%CI 5.938~155.858,P<0.001)、甲状旁腺腺体≥4个(OR=4.355,95%CI 1.027~18.469,P=0.046)是术后发生严重低钙血症的独立危险因素。结论 术前血清碱性磷酸酶、iPTH 1 d下降率≥74.59%、甲状旁腺腺体≥4个是热消融术后发生严重低钙血症的独立危险因素。Purpose To investigate the risk factors of severe hypocalcemia after ultrasound-guided thermal ablation for secondary hyperparathyroidism.Materials and Methods A retrospective case-control study was used to study 91 patients with uremia complicated with secondary hyperparathyroidism in the First People's Hospital of Yulin from May 2019 to May 2023.All patients underwent ultrasound-guided thermal ablation and were divided into severe hypocalcemia group(SH)and non-SH group according to postoperative blood calcium levels.The difference of clinical data between the two groups was compared,and the independent risk factors of SH were investigated by multivariate Logistic regression analysis.Results A total of 317 glands were ablated in 49 cases of microwave ablation and 42 cases of radiofrequency ablation.SH occurred in 57 cases(62.64%)after ablation.The comparison of clinical data between the two groups showed that there were significant differences in the preoperative intact parathyroid hormone(iPTH),decline rate of iPTH 1 d,preoperative serum alkaline phosphatase,the proportion of parathyroid glands≥4 and the total gland volume between the two groups(all P<0.05).Receiver operating characteristic curve analysis was used to obtain the best cut-off point of iPTH 1 d decline rate,the result was 74.59%,the area under the curve was 0.866(95%CI 0.787-0.945)(P<0.05),the sensitivity was 84.2%,and the specificity was 78.1%.Multivariate Logistic regression analysis showed that preoperative alkaline phosphatase(OR=1.015,95%CI 1.005-1.025,P=0.030)and decline rate of iPTH 1 d≥74.59%(OR=30.423,95%CI 5.938-155.858,P<0.001)and parathyroid glands≥4(OR=4.355,95%CI 1.027-18.469,P=0.046)were independent risk factors for postoperative SH(all P<0.05).Conclusion Preoperative alkaline phosphatase and decline rate of iPTH 1 d≥74.59%and the number of parathyroid glands≥4 are independent risk factors for SH after thermal ablation.
