Acute buik- en rugpijn bij een aneurysma van de aorta, en een duodenumperforatie op de CT-scan

- An 82-year old man with a known aneurysm of the abdominal aorta (AAA) presented with a history of acute onset abdominal and back pain of a few hours. He was haemodynamically stable and had pain on pressure over the aneurysm. Ultrasound confirmed the AAA, but could not demonstrate or exclude rupture. Subsequent CT-scan confirmed a non-ruptured AAA and demonstrated a small, curvilinear, hyperdense structure thought to be a fish bone or chicken bone which had perforated the duodenum. On gastroduodenoscopy, a fish bone was found and removed. The patient’s symptoms resolved completely within two days. In patients with a possible ruptured AAA, echographic or CT-scan investigations can confirm or exclude the condition thus avoiding unnecessary surgery. These investigations also gather preoperative data for potential endovascular reconstruction. Before the introduction of new visualization techniques a duodenum perforation resulting from the unnoticed swallowing of a sharp object could only be diagnosed by explorative laparotomy. Delay in diagnosis leads to high mortality.
