Abstract
Complex ventral hernia (CVH) describes large, anterior, ventral hernias. The incidence of CVH is rising rapidly due to increasing laparotomy rates in ever older, obese and co-morbid patients. Surgeons with a specific interest in CVH repair are now frequently referring these patients for imaging, normally computed tomography scanning. This review describes what information is required from preoperative imaging and the surgical options and techniques used for CVH repair, so that radiologists understand the postoperative appearances specific to CVH and are aware of the common complications following surgery. Key Points • Complex ventral hernia (CVH) describes large abdominal wall hernias (e.g. width ≥10cm). • CVH patients are being referred increasingly for preoperative and postoperative imaging. • Imaging is pivotal to characterise preoperative morphology and quantify loss of domain. • Postoperative imaging appearances are contingent on the surgical methods used for CVH repair. • Postoperative complications are depicted easily by imaging.
