Anesthetic management of primary hyperparathyroidism during pregnancy: A case report

Primary hyperparathyroidism (PHPT) during pregnancy is rare. Nevertheless, hypercalcemia secondary to gestational PHPT may be masked by physiological changes in calcium homeostasis during pregnancy. Gestational PHPT constitutes a serious danger to mother and fetus. Surgery is the only curative treatment when conservative treatment could not control the condition. Due to the lack of guidelines concerning PHPT during pregnancy, the optimal anesthetic management of PHPT during pregnancy needs to be individualized. Patient concerns: We report a case of PHPT with successful surgical treatment under combined cervical plexus block and general anesthesia.

She was diagnosed with hypercalcemia, PHPT, a possible parathyroid adenoma, and a 19-week intrauterine pregnancy.

The patient underwent heparin-free hemodialysis before the surgery in the nephrology department in the presence of a cardiologist. She then received a successful parathyroidectomy under combined bilateral superficial cervical plexus block and general anesthesia in her 19th week of pregnancy.

She was released from the hospital with no maternal or fetal complications on postoperative day 9. A healthy baby boy was uneventfully born at 37 weeks of gestation.

We suggest that surgical removal of the lesion after lowering the blood calcium concentration in mid-pregnancy is currently the optimal treatment option for pregnant patients with PHPT. Furthermore, multidisciplinary perioperative management is particularly important.
