Endovascular aortic repair (EVAR) with fenestrated (F-EVAR) or branched (B-EVAR) endografts nowadays represents an indispensable tool of modern patient care in vascular surgery. The purpose of this retrospective study was to evaluate the center's initial experience of F/B-EVAR procedures performed under biplane angiography guidance compared to a historical control group.From January 2020 to March 2022, 80 consecutive patients underwent F/B-EVAR under general anesthesia at a single institution. As from January 2021, the deployment of complex stent grafts (SGs) was performed using an alternative intraoperative imaging modality - a biplane fluoroscopy and angiography. The cohort was divided into monoplane (MPA) and biplane (BPA) groups according to the imaging modality applied. The end points were operation time, fluoroscopy time, radiation exposure, dose of contrast agent and technical success.The MPA group included 59 patients (78% male; median age 74 years, interquartile range [IQR], 66-78 years) and the BPA group 21 patients (85.7% males; median age, 75 years; IQR, 69-79 years). Operation time (median 320 minutes; IQR, 266-376 minutes) vs. (median 275 minutes; IQR, 216-333 minutes) was significantly lower in the BPA group (P = 0.006). Median fluoroscopy time (median 82 minutes; IQR, 57-110 minutes vs. median 68 minutes; IQR, 54-92 minutes), contrast agent (CA) volume applied (median 220 mL; IQR, 179-250 mL vs. median 200 mL; IQR, 170-250 mL) and radiation dose (dose-area product, median 413 Gy x cmF/B-EVAR procedures performed under biplane angiography guidance were associated with a significant reduction of operation time. |
