Influence of Different Diagnostic Procedures on Radiation Dose During Peripheral Interventions

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 CTor 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. *Corresponding author: Magnus Baumhäkel, Caritas Klinikum St. Theresia Saarbrücken, Department of Internal Medicine, D-66131 Saarbrücken, Germany, Tel: 0049-681-406-4243, Fax: 0049-681-406-1753; E-mail: [email protected] Received Date: March 14, 2017 Accepted Date: March 24, 2017 Published Date: March 30, 2017 Citation: Baumhäkel, M., et al.
