Purpose: First web space widening is crucial in the hand function. The skin on the dorsal side of the forearm can provide a thin and pliable skin suitable for first web space reconstruction. Although previous reports have described the use of the posterior interosseous artery (PIA) flap as a reverse-flow flap for treatment of first web space contracture, only a few have addressed its use as a free flap for this purpose. The caliber of the concomitant veins accompanying the PIA is usually small, which may give rise to a problem in the treatment. Methods: Seven patients with first web space contracture were treated with a free PIA flap and the details of the venous anastomosis method were elucidated. Results: Six of seven flaps survived. In a post-burn case, a flap was lost by late thrombosis. The PIA is anastomosed endto-end to the dorsal branch of the radial artery. There are two choices for the recipient venous pedicle: concomitant veins of radial artery and a tributary of the cephalic vein. In our cases, there were four types of venous anastomosis. An average postoperative increase of the thumb radial abduction was 36° and that of the palmar abduction was 35°. Conclusion: Since the caliber of the concomitant veins accompanying the PIA is small, a careful scheme for venous anastomosis is essential in the treatment of first web space contracture using the free PIA flap. Key Words: Free posterior interosseous artery flap, First web space contracture, Venous anastomosis Arch Hand Microsurg 2019;24(4):408-415.

Background Flap surgery, integral to various reconstructive procedures, necessitates accurate identification of perforator locations for optimal outcomes. While Color Doppler Sonography (CDS) has been a staple in preoperative planning, its limitations in providing a comprehensive overview of perforator relationships prompted exploration of alternative imaging modalities. This study introduces the application of a novel technique, three-dimensional computed tomography angiography fusion imaging (3D-CTA-FI), for precise dorsal interosseous artery perforator localization in forearm flap surgery. Method A retrospective investigation including 23 patients undergoing forearm flap surgery of posterior interosseous artery perforator was conducted, employing a two-phase computed tomography angiography (CTA) protocol. Utilizing Mimics software, 3D models of vascular structures were meticulously reconstructed. Surgical procedures were guided by the 3D-CTA-FI, and accuracy of CDS and 3D-CTA-FI was evaluated by comparing indicated and actual perforator positions. Results All flaps exhibited viability, with 3D-CTA-FI consistently portraying accurate depictions of vascular pedicles and perforators. The mean discrepancy between indicated and actual perforator positions was 2.9 ± 1.7 mm (Group 1) and 2.4 ± 1.7 mm (Group 2), accompanied by excellent accordance rates of 47.8% and 60.9%, respectively. Conclusions Three-dimensional computed tomography angiography fusion imaging (3D-CTA-FI) emerges as a valuable tool for forearm flap surgery. Its ability to provide detailed, accurate images of perforators enhances preoperative planning and intraoperative precision, making it a feasible and beneficial addition to clinical practice.
