Abstract

Purpose

The aim of the study was to investigate the prevalence of the noncardiac collateral findings during multislice computed tomography coronary angiography (MSCT-CA).

Materials and methods

Six hundred and seventy patients undergoing MSCT-CA with 16-slice and 64-slice CT scanners for suspected atherosclerotic disease of the coronary arteries were retrospectively reviewed. All data sets obtained with a large field of view (FOV) were analysed by two radiologists using standard mediastinal and lung window settings. Collateral findings were divided according to clinical importance into nonsignificant, remarkable and compulsory to be investigated.

Results

Eighty-five percent of patients revealed coronary artery disease (CAD). Only 138/670 (20.6%) were without any additional finding. An additional 1,234 findings were recorded: nonsignificant 332 (26.9%), mild 821 (66.53%), compulsory for study 81 (6.56%). A total of 81 patients (12.08%) had significant noncardiac pathology requiring clinical or radiological follow-up. Among these, newly discovered pathologies were revealed in two patients (2.46%).

Conclusions

A significant number of noncardiac findings might have been missed in MSCT-CA scans; the appropriate approach should be as a team trained in cardiology and radiology.

Riassunto

Obiettivo

Scopo dello studio è valutare la prevalenza dei reperti collaterali non cardiaci durante l’esecuzione di angiografia coronaria mediante TC multistrato (AC-TCMS).

Materiali e metodi

Sono stati valutati retrospettivamente seicento e settanta pazienti sottoposti ad AC-TCMS con apparecchio a 16 e 64 strati per sospetta coronaropatia. Due radiologi hanno valutato separatamente tutti i datasets ottenuti con un ampio campo di vista utilizzando le finestre di vista mediastinica e polmonare. I reperti collaterali identificati sono stati divisi a seconda dell’importanza clinica in non significativi, significativi e in obbligo di ulteriori accertamenti.

Risultati

Nell’85% dei pazienti è stata riscontrata una malattia aterosclerotica delle arterie coronarie. Solamente 138/670 (20,6%) dei pazienti è risultata priva di reperti collaterali. Sono stati riscontrati 1234 rilievi accessori, divisi in 332 (26,9%) non significativi, 821 (66,53%) significativi e 81 (6,56%) in obbligo di ulteriori accertamenti. In 81 (12,08%) sono state riscontrate patologie che hanno comportato ulteriori accertamenti o un follow-up radiologico. In 2 di questi pazienti l’esame ha permesso di diagnosticare due neoplasie (2,46%).

Conclusioni

Un numero significativo di reperti accessori potrebbe essere stato perso nella lettura delle angiografic coronariche mediante TCMS. L’approccio appropriato dovrebbe prevedere la lettura degli esami da parte di un team esperto in Cardiologia e Radiologia.
