Parathyroidectomy for secondary hyperparathyroidism in chronic renal failure Background: Parathyroidectomy is indicated in patients with chronic renal failure and secondary hyperparathyroidism that is persistent and refractory to treatment. Aim: To assess the effects of parathyroidectomy in patients with chronic renal failure and symptomatic hyperparathyroidism. Patients and Methods: Prospective evaluation of 33 patients (20 females), aged between 23 and 78 years, with chronic renal failure and secondary hyperparathyroidism that were subjected to a total parathyroidectomy and autotrasplantation. Patients were followed for six months measuring parathormone (PTH), calcium and phosphorus. Results: In the postoperative period, one patient had a cervical hematoma that had to be operated. Mean serum PTH levels at the moment of hospital discharge and at six months, were 832 and 212 pg/ml respectively. All patients that had bone pain experienced a notable reduction of this symptom on the morning after surgery. One patient had a relapse of her hyperparathyroidism. Conclusions: Parathyroidectomy is safe and effective for secondary hyperparathyroidism in patients with chronic renal failure.
RESUMENLos quistes broncogénicos son malformaciones congénitas del árbol traqueobronquial que se ubican preferentemente en pulmones y mediastino, siendo excepcional su aparición en el cuello. Esta situación conlleva que ante una masa cervical de esta naturaleza se postulen diferentes diagnósticos clínicos de lesiones cervicales que son más corrientes, tales como quiste tiroideo, tirogloso, branquial y tímico, entre otros. La imagenología informa sobre el carácter quístico de la lesión pero no proporciona hallazgos específicos. Durante la intervención quirúrgica tampoco es posible establecer el diagnóstico, puesto que la masa simula los quistes cervicales congénitos más frecuentes. El diagnóstico definitivo se establece mediante la biopsia al constatar en la pared del quiste epitelio respiratorio. Comunicamos el caso de una mujer que presentó un quiste broncogénico de ubicación cervical y discutimos algunos aspectos de esta interesante condición.PALABRAS CLAVE: Quiste broncogénico, quiste congénito, cuello.
SUMMARYBronchogenic cysts are congenital malformations of the tracheobronchial tree that are mainly located in the lungs and mediastinum. Occasionally, they can appear in the neck, generating a cervical mass. Pathology gives the definitive diagnosis. We report a 19 years old female that consulted for an asymptomatic central cervical mass. On examination, a 4 cm diameter painless suprasternal nodule was palpated. Cervical ultrasound and CAT scan showed a cystic lesion. The cyst was completely excised surgically and the pathological report disclosed a bronchogenic cyst.
