Negative pressure wound therapy with a fenestrated penrose drain for refractory seroma following ischial flap: A case report

Figure 1 Schematic depiction of negative pressure wound therapy combined with a fenestrated Penrose drain. A: A cylindrical 6 mm Penrose drain, fenestrated to enhance fluid evacuation, was inserted with its distal end placed at the base of the dead space; B: A portion of the negative pressure wound therapy foam dressing was cut to create a space where the opposite end of the fenestrated Penrose drain was positioned.
