Abstract

Aim: Interventional radiology procedures using ionizing radiation were frequent and become more and more complex. While determinants of radiation exposure during coronary angioplasty have been examined intensively during the last decade, available data regarding peripheral interventional procedures and especially the influence of pre-interventional diagnostic procedures on radiation exposure are limited.
Materials and Methods: Procedural data of 289 consecutive patients who underwent peripheral were included in this study. Radiation exposure was analysed using the dose area product (DAP, Gy*cm²) and total time of fluoroscopy dependent on region of intervention and type of diagnostic procedure prior to intervention.
Results: Information about vascular status of patients before the intervention led to a significant decrease of the dose area product irrespective of the region of intervention (iliac, femoro-popliteal, crural, multi-vessel, p < 0.05). Reduction of radiation exposure was highest with prior angiography or a CT- or MR-angiography (p < 0.01), whereas a diagnostic vascular ultrasound tended to decrease radiation exposure of patients (n.s.). Fluoroscopy time was not affected by the kind of diagnostic procedure (n.s.).
Conclusions: Patients´ radiation dose during peripheral interventional procedures is strongly dependent on vascular region, precise information about vascular status and previous vascular imaging. Thus, physicians should emphasize accurate vascular diagnostic procedures prior to peripheral intervention.
