The effect of bilateral truncal ligation of the inferior thyroid artery on parathyroid function is prospectively analyzed in two homogeneous groups of 10 patients treated by total thyroidectomy, with (G1) and without (G2) truncal ligation, comparing immediately postoperative and late serum calcium levels. A significant decrease in mean calcemic levels (minimal ones 2.1, with n.v. 2.1-2.6 mmol/l) was observed in both groups no longer than in the first postoperative days. There was no significant difference in global (clinical + laboratory) hypocalcemia rate (G1 = 0-30% vs G2 = 10-40% respectively); nevertheless hypocalcemia was noted paradoxically to occur more frequently in G-2 patients, out of which one developed a permanent hypoparathyroidism.
对两组各10例接受全甲状腺切除术的患者进行前瞻性分析，比较甲状腺下动脉双侧主干结扎对甲状旁腺功能的影响。一组（G1）进行主干结扎，另一组（G2）不进行主干结扎，对比术后即刻及晚期血清钙水平。两组患者术后均在数天内出现平均血钙水平显著下降（最低降至2.1，正常范围为2.1 - 2.6 mmol/L）。两组总体（临床 + 实验室）低钙血症发生率无显著差异（G1分别为0 - 30%，G2分别为10 - 40%）；然而，矛盾的是，G2组患者低钙血症更频繁发生，其中1例发展为永久性甲状旁腺功能减退。
