Surgical drain induced subgaleal hematomas and skin necrosis in pediatrics: a case report.

introductionSubgaleal drainage is often being used in craniotomy procedures. It's not only offers advantages but also carries a risk of life-threatening complications. Here, we present a rare case of subgaleal hematoma and skin necrosis caused by placement of subgaleal drainage in a pediatric patient after a craniotomy procedure. CASE REPORT: We reported a 6-months-old child who came to our institution complaining of uncontrolled eye movements which occurred 4 months earlier. From the CT scan and MRI, it was found that the patient had a mass in his suprasellar region, which suggested a suprasellar tumor. She underwent a mass resection procedure, but unfortunately, 3 days after the surgical procedure, the wound appeared necrotic, with a blackish color around the drain. The necrotic wound was suspected due to vacuum subgaleal drain placement. The wound was cleaned and the suture removed, but the necrotic area was still there. Four days after the surgery, the patient clinical condition got worse. After 17 days of treatment with no significant improvement, unfortunately, the patient died. DISCUSSION: The mechanism of subgaleal hematoma and skin necrosis induced by the Redon drain possibly related to mechanical compression by the drain, which damage perforating vessels and subsequently disrupt skin vascularization, combined with vascular stasis as given by negative pressure of the drain. This induced skin ischemia lesion which later contributes the necrotic formation.

conclusionThe subgaleal hematoma and skin necrosis as a complication of subgaleal redon drain in pediatric are rare phenomenon and likely under reported. The possible underlying mechanism was that drain's negative pressure disrupt subgaleal tissue and induce necrotic formation. Even the complication is rare compared to older children, yet it has been linked to an increased risk for infection, morbidity, and mortality.
