[Clinical treatment experience of thyroid cancer with heart disease]

Objective: To explore the perioperative clinical treatment of thyroid cancer patients with heart disease. Methods: A retrospective analysis was conducted on 39 thyroid cancer patients with heart disease admitted to the Department of Otorhinolaryngology Head and Neck Surgery, Beijing Anzhen Hospital,Capital Medical University from April 2014 to February 2018,including 25 males and 14 females, the age ranged from 59 to 75 years,with an average age of 67.3±6.2 years. Perioperative clinical monitoring indicators included cardiac ultrasound left ventricular ejection fraction (LVEF), degree of vascular stenosis revealed by coronary CT, hypersensitive troponin I (TNI), b-type natriuretic peptide (BNP), fibrinogen degradation products,and coagulation indexes. This panel of patients comprised 26 cases with 50% ≤ LVEF<60%,10 cases with 40% ≤ LVEF<50%, 3 cases with 36% ≤ LVEF<40%, 27 cases with 0≤BNP<100 ng/L, 7 cases with 100≤BNP<400 ng/L, and 5 cases with 400≤BNP<700 ng/L. Coronary CT showed no coronary artery stenosis>75%. The vascular graft was patent and the coronary artery after stenting was unobstructed. For 3 patients with LVEF<40% and 5 patients with BNP>400 ng/L,cardiotonic,diuretic,and nutritional myocardial therapy were used for 1 week. SPSS 17.0 software was used to analyze the data. Results: All 39 patients successfully completed the operation under general anesthesia,including 32 cases of total thyroidectomy,7 cases of glandular lobe and isthmic resection,and 40 cases of lateral neck dissection. One patient developed heart failure three days after surgery and was discharged after two weeks of treatment. No other cardiac related events,cerebrovascular and pulmonary thrombosis occurred during the perioperative period. The anesthesia preparation time was significant different between the group with 0≤BNP<100 ng/L and 50%≤LVEF<60% and the group with 0≤BNP<100 ng/L and 36%≤LVEF<50%. Conclusions: Multi-indicators were utilized to adequately assess cardiac function before surgery. According to the results of cardiac ultrasound and coronary CT examination, the corresponding treatment should be conducted to improve the cardiac function. After the perioperative risk assessment and management of thyroid cancer patients with heart disease,standardized thyroid cancer surgery can be performed safely.
