CT-guided percutaneous ethanol ablation of parathyroid adenoma / 介入放射学杂志

ABSTRACT

Objective To validate the theraputic efficacy of percutaneous ethanol injection(PEI) for hyperparathyroidism caused by parathyroid adenoma.Methods One case of parathyroid adenoma underwent PEI whose diagnosis was comfirmed by biopsy. The 22 gauge needle was punctured into the adenoma under CT guidance and ethanol was injected into the lesion at multiple points. Results The CT images obtained 6 months after 2 times of CT guided PEI revealed that the volume of the adenoma decreased markedly together obviously with decrease of enhancement after the injection of contrast media. The level of serum parathyroid hormone, calcium and phosphorous returned normal 2 days to 12 months after the management. The clinical manifestations improved markedly.Conclusions CT guided PEI is a minimally invasive and highly effective theraputic modality for hyperparathyroidism. It can serve as an important supplement to surgery.
