Abstract:
BACKGROUND: Patients with vascular diseases commonly have coronary artery disease and associated cardiac problems. Therefore, their underlying heart diseases may be induced or exacerbated after vascular surgery. The effectiveness of SPECT imaging, which is a relatively simple and non-invasive imaging modality, for assessing these underlying heart diseases is still controversial. This study was performed to evaluate the clinical effect of tests and treatment based on SPECT imaging prior to vascular surgery on the development of post-operation cardiac complications. MATERIAL AND METHOD: Sixty three patients who were treated at Inje University Pusan Paik Hospital between April 2004 and September 2007 and who underwent adenosine infusion technetium-99m (Tc-99m) tetrofosmin SPECT imaging prior to vascular surgery were selected for this study and we retrospectively reviewed their records. RESULT: The sensitivity and specificity of detecting a perfusion defect on SPECT to predict the development of cardiac complications was relatively low at 41.2% and 52.2%, respectively. However when coronary angiographies were done on the patients with abnormal SPECT and this was followed by aggressive treatment such as coronary artery intervention and coronary artery bypass grafting based on the angiography results, there was a tendency for lower cardiac complication rates. CONCLUSION: SPECT imaging shows low effectiveness as a screening test for predicting cardiac complications after vascular surgery.
