Complications Infection Scarring, due to unrelieved tension on the laceration Cross-hatching (train tracks) due to pressure on the skin surface caused by the wide-deep loop Cutting of skin by sutures, particularly by the narrow-shallow loop, particularly if this loop is placed prior to the wide-deep loop Ischemia and necrosis, which occur more often than with simple interrupted or continuous sutures Equipment Wound hygiene and closure techniques need not be sterile procedures.
