Preoperative CT angiography reduces surgery time in perforator flap reconstruction

• The use of perforator flaps in breast reconstructions has increased considerably in the past decade. A disadvantage of the perforator flap is difficult dissection, which results in a longer procedure. During spring 2006, we introduced CT angiography (CTA) as part of the diagnostic work-up in perforator flap reconstructions to visualise each perforator more accurately. The main objectives were to reduce surgery time and the number of complications. A chart review was conducted 1 year after CTA introduction to investigate if these objectives were met. MATERIALS AND METHODS: Patients with a deep inferior epigastric perforator (DIEP) flap who underwent preoperative analysis through CTA were retrospectively evaluated. The population <0.001) than in the control group, 264 min (SD+/-62) versus 354 min (SD+/-83), respectively. There was a tendency for fewer complications in the CTA group compared with the control group. All flaps were successful in the CTA group. In the control group, one flap failed and partial necrosis occurred in three flaps. The differences were not statistically significant. CONCLUSIONS: Preoperative CTA in the assessment of vascular anatomy during perforator flap reconstruction was safe and reliable. It helped reduce surgery time, and may prevent the number of postoperative complications.
