DermaClose external tissue expander device

Case contributed by Jerry Jiang


Previously healthy male with history of large traumatic ventral hernia status post abdominal reconstruction.

Patient Data

Age: 50 years
Gender: Male

Mild diffuse bilateral peribronchial thickening and streaky bibasilar atelectasis. Two Harrington rods and pedicle screws transfixed between T7 and T11 vertebral bodies in this patient with posterior spinal fusion demonstrate no evidence of hardware failure or loosening.

A plate and multiple screws are seen transfixed at the left clavicular shaft without evidence of hardware failure or loosening on this one-view exam. 

Six anchors/suture-like densities and the expander are seen projecting in the upper abdomen in this patient with a known history of abdominal wall defect reconstruction with placement of a DermaClose external expander device with 6 sutures.

Case Discussion

The patient had suffered an MVA with multiple severe intra-abdominal injuries. After stabilization, the patient had 13 cm x 9 cm abdominal wall diastasis extending from 9 cm above the pubis to the xiphoid process, with a skin graft overlying the abdominal contents. The patient underwent a multi-stage abdominal wall reconstruction and is now status post placement of DermaClose device for tissue expansion.

This case demonstrates the radiographic appearance of the DermaClose device to aid diagnosis and prompt recognition on imaging.
