A 21-year-old female patient who complained of a sunapping hip for several years was treated by z-figure incision of the iliotibial band. While the suapping phenomenon disappeared, the surgical wound did not heal and skin closure was performed three times thereafter, with a pin hole sinus, subcutaneus bleeding and secretion remaining. Neither infection nor allergic reation against nylon suture material were found.
Laboratorly data consistent with von Willebrand's disease was found, but there was no bleeding tendency in her past history. Wound closure finally succeeded following currettage of the wound and administration of Vit. K (i. v., 1g×7 days) and Vit. C (p. o., 1g×18 days).
The subcutaneus bleeding was thought to be due fo a deficiency of Vit. K caused by several intravenous and parenteral antibiotics (CEZ, CTM, CLL).
