A case of scalp avulsion with prolonged ischemic time: indocyanine green angiography can aid in predicting replant survival

BACKGROUND: Microsurgical replantation has become the most favorable treatment option for scalp avulsion. However, the accurate prediction of postoperative replant viability remains challenging. CASE PRESENTATION: In this article, we showed that (indocyanine green angiography, ICGA) can provide a much more precise prediction of replant necrosis than conventional clinical assessment in a rare case of complete scalp avulsion with prolonged ischemia time. CONCLUSION: Clinical assessment of replant survival may be misleading in cases of complex tissue injuries and prolonged ischemic stress. This case provides insight into the promising utility of ICGA as an important adjuvant tool to better assess tissue perfusion and viability in scalp avulsion and possibly other types of replantation.
