INTRODUCTION: The relationship between the intra-operative concentration of parathyroid hormone (IOPTH) and the long-term outcome of @entity1 intervened due to @entity459 ( @entity459 ). @entity1 AND METHODS: A prospective observational study was performed with 120 @entity1 . Three determinations were made of @entity461 in blood: baseline, when the diseases gland was located, and 10 minutes after its extirpation. The @entity460 , @entity461 and @entity560 ( @entity14282 ) levels were measured during follow up. RESULTS: A decrease in IOPTH > 50% was observed in 96 (80%) @entity1 , and the post-extirpation value returned to the normal range (Group I), in 18 (15%) a decrease of > 50% but the final value remained higher than normal (Group II) and in 6 (5%) the decrease was<50% (Group III). Persistent @entity459 was detected during follow up in 6 @entity1 (5%): one in Group I (1%), 3 (16.7%) in II and 2 (33.3%) in group III (P<.001). The risk of persistent @entity459 was higher in Group II (odds ratio: 19; 95% CI: 1.85-194) and in Group III (odds ratio: 47; 95% CI: 3.53-639). There were no cases of recurrent @entity459 . A normal @entity460 with an increased @entity461 was detected in 20 @entity1 of Group I (20.8%), 11 (61.1%) in II and 3 (50%) in III (P<.001). These @entity1 had a lower concentration of post-operative @entity560 (17 ng/ml, range: 24; compared to 28 ng/ml, range: 21) (P=.008) and higher frequency of hypovitaminosis D (70.6% compared to 26.2%) (P>.001). CONCLUSION: The risk of persistent @entity459 is higher when the IOPTH decreases more than 50% but still remains high.
