Intraoperative Blood Flow Analysis of DIEP vs. ms-TRAM Flap Breast Reconstruction Combining Transit-Time Flowmetry and Microvascular Indocyanine Green Angiography

Abstract: Background: Vascular patency is the key element for high flap survival rates. The purpose of this study was to assess and compare the blood flow characteristics of deep inferior epigastric perforator (DIEP) and muscle-sparing transverse rectus abdominis musculocutaneous (ms-TRAM) flaps for autologous breast reconstruction. Methods: This prospective clinical study combined Transit-Time Flowmetry and microvascular Indocyanine Green Angiography for the measurement of blood flow volume, vascular resistance, and in… Show more

“…Therefore, CT angiography can be used preoperatively to provide detailed information about the vessel anatomy [ 41 ]. Moreover, imaging techniques such as indocyanine green angiography or blood flow analysis can be used intraoperatively to further ameliorate reconstruction safety and prevent flap loss [ 42 , 43 ].…”

“…Laser Doppler flowmetry, which has been used in other studies [ 41 , 42 ], can record the tissue perfusion continuously, while the measurements in our study were only taken at specific timepoints. Indocyaningreen angiography is used predominantly to assess tissue perfusion in flap surgery [ 43 , 44 ]. The differences between well-perfused, mal-perfused and non-perfused areas of the flaps are clearly shown.…”

“…Utilization of ICG fluorescence angiography is a well-standardized laser-driven technology for real-time perfusion analysis of tissue perfusion in various fields to differentiate between viable and nonviable tissue (20,21). In reconstructive surgery, ICG has been mostly investigated in the perioperative assessment of soft tissue perfusion, e.g., in autologous and alloplastic breast reconstruction surgery (22). However, little is known about the value of ICG angiography in free vascularized bone grafts (23).…”
