Re-operative surgery for recurrent or persistent primary hyperparathyroidism.

BACKGROUND: While initial surgery for primary hyperparathyroidism, in experienced hands, will result in a cure in 98% of cases, re-operative surgery remains a significant challenge. Because attitudes as to who should perform initial exploration for hyperparathyroidism are significantly different around the world, the approach to re-operative surgery may also vary. The aim of the present study was to examine a local experience of re-operative surgery for recurrent or persistent primary hyperparathyroidism. METHODS: Information on indications for surgery, the procedure performed, pathology and complications of all re-operative procedures for primary hyperparathyroidism in the period January 1962 to December 1996 were obtained from a prospective database. RESULTS: Sixteen patients with persistent (n = 12) or recurrent (n = 4) primary hyperparathyroidism were treated in the unit over the study period. Eight patients had their initial operation within the unit at Royal North Shore Hospital and eight were referred from elsewhere for re-operation. Nine of the 12 patients with persistent hyperparathyroidism were cured by re-operation with failures due to spillage at first operation (n = 1) or failure to find any additional pathology (n = 2). All four patients with recurrent hyperparathyroidism were cured. All the failures occurred early in the learning phase of the unit, with a 100% cure rate for re-operative procedures performed in the last 15 years. The most common finding in patients referred from elsewhere with a failed initial operation was a missed inferior adenoma in association with the thymus. Localization studies had a variable sensitivity, with sestamibi scintigraphy, selective venous sampling and ultrasonography providing the most reliable information. CONCLUSIONS: Re-operative surgery for persistent or recurrent hyperparathyroidism is an uncommon procedure in Australia when compared to major centres in the USA. Successful surgery depends upon experience and an accurate knowledge of the embryology and anatomy of the parathyroid glands.

The predictive value of troponin T in patients who underwent an extracardiac surgery operation.

UNLABELLED: Purpose of the study is the research of the diagnostic value of the determination of Troponin T in relation with the other cardiac enzymes in patients who underwent extracardiac surgery operation. METHODS: 42 pts (M = 24, F = 18, mean age 51.7 +/- 17 years) who underwent a surgery operation were studies. For all pts serum enzyme CPK, CPK MB, SGOT and Troponin T was determined 24 hours before and after the operation. RESULTS: increased value of CPK was observed in all patients. In 14.3% of pts was found abnormal value of CPK. In 1 pt CPK MB was found increased. In no one of the above pts was observed an increased value of Tr-T. No one of the pts had ECG changes and clinical symptoms indicative of ischemic heart disease. CONCLUSIONS: these results suggest that the determination of Tr-T in serum is more useful diagnostic index for myocardial cell injury in pts who underwent an extracardiac surgery because is not detected in skeletal muscle injury.

Coronary artery surgery. Operative technique and patient education.

Coronary artery surgery, the preferred technique for myocardial revascularization in patients with ischemic heart disease, promptly increases blood flow to areas of the myocardium distal to the coronary obstruction. CAS completely relieves angina in 90% of patients. The risk of 1 to 5% is decreasing as operative technique and patient selection improve. Patients having CAS need comprehensive preoperative and discharge teaching to restore them to normal, active, optimistic lives.

[The dynamics of the more important indices of the external respiration following heart surgery operations].

A retrospective study comprising patients undergone cardiac surgery is done. In the study some measurable parameters of external breathing are followed up. The measurements are carried out by portable respiratory monitor. The following parameters are included in the study: FVC, FEV1, PEF and FEF 25-75%. The lowering values of these parameters is taken into account and the degree and way to restore these values is discussed.

[The morphological characteristics of the circulating blood after massive reinfusion in operative surgery].

Intraoperative autologous blood extravasation represents an adequate biogenic medium for prompt and complete blood volume compensation following acute hemorrhage. The efficiency of the procedure is closely related to the functional characteristics of the ATS applied and its potential adaptation to the operative field. Over a 5-year period, autologous blood reinfusion is done in 151 patients with acute intraoperative hemorrhage associated with various types of operative interventions. The hemogram is analyzed in 32 cases undergoing reconstructive surgery of arterial vessels, with massive intraoperative hemorrhage and reinfusion (exceeding 25 per cent of the circulating volume). The quantity of AB represents 92.7 per cent of the blood loss volume; reinfusion is effected using the patient's own ATS. The circulating erythron level (its binding portion) remains within reference limits throughout the full post-reinfusion period; a tendency towards complete correlative dependence between the values of Hb, Er, Ht and the volume of reinfusion done intraoperatively is outlined (r = 0.84-0.92; p < 0.05-0.001). Free hemoglobin concentration in the transfusion product is low (66.8 +/- 24.2 mg/100 ml blood), while in the post-reinfusion circulating blood it quickly returns to normal, at 2 hours--in 87.5 per cent of the samples, and at 6 hours--in 100 per cent (r = 0.66-0.80; p > 0.001). The minimal morphologic changes in AB upon its deposition and reinfusion warrant the assumption that it is the most suitable transfusion medium, contributing to normalization of the hematologic indicators of acute hemorrhage during operative surgery.
