“…ICG angiography has recently been used for the study of arterialized venous flaps, proving reliable in the study of the vascular tree of the venous flaps and allowing modification of the operative plan to avoid venous congestion and flap necrosis [ 9 ]. Similarly, in our clinical case, the use of indo-cyanine green angiography guided the surgical choice toward an arteriovenous anastomosis rather than regularization of the stump.…”

Patient: Male, 44-year-old Final Diagnosis: Amputated thumb Symptoms: Amputated thumb Clinical Procedure: — Specialty: Plastic Surgery • Surgery Objective: Unusual clinical course Background: The absence of valid vessels for the anastomosis constitutes a contraindication to replantation, but the need for arterial vessels in good condition has recently been questioned and some authors have proposed the arterialization of the veins with promising results. However, this method is not routine in replantation and it is unclear what conditions can establish venous congestion and loss of the replanted segment. Case Report: We detail a case where indocyanine green aids in evaluating arterialization of a vein during thumb replantation in a 40-year-old smoker following a crush injury. Multiple attempts to anastomose the princeps pollicis and its collateral vessel failed due to a thrombus formation, leaving the finger non-perfused despite urokinase treatment. To confirm the absence of reperfusion, we administered 0.3 mg/kg of indocyanine green through an upper limb peripheral vein. Observing no reperfusion, we located a suitable radial dorsal vein and performed an arteriovenous anastomosis at the proximal phalanx level. Indocyanine Green Angiography (IGA) revealed a slightly delayed reperfusion but a effective venous outflow. We did not consider it necessary to perform additional venous anastomoses other than the single dorsal radial venous anastomosis. Conclusions: This single case report shows the potential of indocyanine green as a valid aid to evaluate the perfusion of the replantation and also any early venous congestion, being able to modify the operative plan accordingly.

Objective Severe hand electrical injuries often occur in functional areas such as joints; the repair requires attention to both appearance and function due to the visibility of the hand. This study aimed to present the clinical experience of successfully repairing hand electrical injuries using improved forearm venous flaps. Methods From 2020 to 2022, 15 cases of severe hand electrical injuries were diagnosed, including 10 males and 5 females. Among them, 6 cases were repaired in the first web space, 4 in the thumb, 3 in the index finger, 2 in the middle finger, 2 in the ring finger, and 2 in the little finger. The size of venous flaps ranged from 2.0 cm × 1.8 cm to 12 cm × 4.0 cm. All patients underwent repair using improved forearm venous flaps. The follow-up period ranged from 5 to 8 months. Results All flaps survived without serious complications. All patients were satisfied with the postoperative aesthetics and function of their hands. Conclusion The improved forearm venous flap is a simple and reliable method for repairing hand electrical injuries.
