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.

A: Wound dehiscence with refractory seroma on left ischium and right trochanter sore; B: Insertion of a fenestrated Penrose drain though flap margin into dead space on left ischium; C: Negative pressure wound therapy combined with a fenestrated Penrose drain to remove the fluid collection and press the dead space; D: Two months after inferior gluteal artery perforator fascio-cutaneous transposition flap surgery on left ischium and V-Y musculocutaneous flap on right trochanter.
