Myocardial perfusion scintigraphy

Gelişmiş ve gelişmekte olan ülkelerin çoğunda en sık ölüm nedeni kardiyovasküler hastalıklardır. Miyokard perfüzyon sintigrafisi (MPS) koroner arter hastalığı tanı ve prognoz belirlenmesinde, viabilite tanımlanmasında ve revaskülarizasyon sonrası iyileşmenin değerlendirilmesinde günümüzde nükleer kardiyolojide en sık uygulanan işlemdir. Bu yazıda MPS’nin tekniği, miyokardial radyofarmasötik ajanlar, stres protokolleri, yorumu etkileyen faktörler ve MPS’nin prognostik değeri incelenmiştir.Cardiovascular diseases remain the principal cause of death in the majority of developed and in developing countries. Myocardial perfusion scintigraphy (MPS) is currently most performed procedure in nuclear cardiology for diagnosis and prognosis of coronary artery disease, the characterisation of viability and the assessment of potential recovery after coronary revascularisation. This manuscript reviews the technique of MPS, myocardial radiopharmaceutical agents, stress protocols, the factors influencing the interpretation and the prognostic value of MPS

Hypocalcemia development in patients operated for primary hyperparathyroidism: Can it be predicted preoperatively?

ABSTRACT Objective: Primary hyperparathyroidism (PHP) is a common endocrine disease, and its most effective treatment is surgery. Postoperative hypocalcemia is a morbidity of parathyroid surgeries, and it may extend hospitalization durations. The purpose of this study is to determine the predictive factors related to the development of hypocalcemia and hungry bone syndrome (HBS) in patients who underwent parathyroidectomy for PHP. Materials and methods: Laboratory data comprising parathyroid hormone (PTH), calcium, phosphate, 25-OHD, albumin, magnesium, alkaline phosphatase (ALP), blood urea nitrogen (BUN), and thyroid stimulating hormone (TSH) of the patients were recorded preoperatively, on the 1 st and 4 th days postoperatively, and in the 6 th postoperative month, and their neck ultrasound (US) and bone densitometry data were also recorded. Results: Hypocalcemia was seen in 63 patients (38.4%) on the 1 st day after parathyroidectomy. Ten patients (6.1%) had permanent hypocalcemia in the 6 th month after surgery. Out of the patients who underwent parathyroidectomy for PHP, 22 (13.4%) had HBS. The incidence of postoperative hypocalcemia was higher in patients who underwent parathyroidectomy for PHP, who had parathyroid hyperplasia, and who had osteoporosis. Preoperative PTH, ALP, and BUN values were higher in those patients who developed HBS. Furthermore, HBS was more common in patients who had osteoporosis, who had parathyroid hyperplasia, and who underwent thyroidectomy simultaneously with parathyroidectomy. Conclusions: As a result, patients who have the risk factors for development of hypocalcemia and HBS should be monitored more attentively during the perioperative period
