Intraoperative argatroban vessel irrigation during microsurgical anastomosis in heparin-induced thrombocytopenia patients: About two cases.

Patients with heparin-induced thrombocytopenia or confirmed allergies to heparin have a contraindication to heparin therapy, which poses a problem for intraoperative free flap irrigation in reconstruction. The use of argatroban as an alternative to heparin allowed us to perform a free flap for leg salvage and a deep inferior epigastric perforator flap for breast reconstruction without microvascular complication, with a 0.01 mg/mL solution. We reported two cases of using an alternative treatment to heparin in an emergency and planned surgeries for vessel irrigation during microsurgical anastomosis reconstruction without microvascular complications, suggesting the reliability and effectiveness of its use in case of contraindication to heparin.
