Repeated surgeries in primary hyperparathyroidism

: Surgery was performed in 161 patients with primary hyperparathyroidism (PHPT). Eight of 161 patients underwent repeated surgeries. In 6 patients persistent PHPT was associated with hyperplasia of parathyroid glands (PTG), in 1 -- with adenoma of PTG missed during the first surgery. In 4 of them hyperplastic PTG are located in anterior mediastinum, in 1 -- in posterior. In 2 patients with verified hyperplasia of PTG repeated surgeries were limited in the region of the neck. During repeated surgery in one patient recurrence of PTG cancer was diagnosed. Specific group consisted of 8 patients with non-severe disturbances of renal function which remained in early and long-term period after surgery. Levels of parathyroid hormone and ionized calcium were normal or insignificantly elevated. Dynamic observation was recommended for all patients of this group.
