Differential Visualization of Arterial and Venous Flow in Deep Inferior Epigastric Perforator Imaging with Vector-Flow Perforator Phase Contrast Angiography (pPCA)

Perforator flaps are commonly used in reconstructive surgery, with decreased donor site morbidity and increased flexibility in flap design cited as advantages over traditional techniques.1 Vascular imaging is often obtained preoperatively in order to facilitate flap design and execution.2-3 Computed tomographic angiography (CTA) is widely used in a variety of different perforator flaps, but possesses a number of drawbacks. CTA utilizes ionizing radiation, which is of particular concern to the patient population receiving perforator flap surgery as many of them are young and with greater than usual susceptibility to radiation induced neoplasia due to risk factors such as BRCA gene mutations and Li-Fraumeni Syndrome.
