Summary

Laparoscopic port insertion is a potential cause of trauma to the inferior epigastric artery, resulting in pseudo-aneurysm formation. Treatment of pseudo-aneurysms includes thrombin injection, coil embolisation, embolisation with N-butyl cyanoacrylate, compression therapy or surgical excision and ligation. The authors present a case of pseudo-aneurysm caused by port insertion during laparoscopic sigmoid colectomy. The pseudo-aneurysm was identified using CT and Doppler ultrasound scans, but underwent spontaneous resolution with cessation of flow prior to intervention. The patient was therefore discharged, but he presented again as an emergency with rupture of a clinically infected pseudo-aneurysm and needed emergency surgical intervention.
