甲状腺手术后併发甲状旁腺机能不足,大多为手术时误将甲状旁腺与甲状腺一併切除,或由于手术时钳夹结扎甲状旁腺而致甲状旁腺机能不足。至于因甲状腺下动脈被结扎使甲状腺血液供给不足而引起之甲状旁腺机能不足,值得怀疑,因为甲状腺后壁有气管动脈、喉上动脈、咽升动脈及食管动脈等分支与甲状腺均有交通支相通,不易引起血供不足。甲状旁腺 Thyroid surgery complicated by parathyroid hypothyroidism, mostly parathyroid surgery with the thyroid gland removed together, or due to surgery when the clamp ligating the parathyroid parathyroid hypoplasia. As hypothyroidism is ligation of the thyroid blood supply caused by inadequate parathyroid, is suspected, because the posterior wall of the thyroid tracheal, laryngeal, pharyngeal and esophageal arteries and other branches and Thyroid traffic support, are not easy to cause lack of blood supply.
