Intra-abdominal haemorrhages. A-B) In a 66-year-old man with severe peripheral artery disease (PA), shortly after percutaneous transluminal angioplasty (PTA) and stenting of the left femoral artery with ipsilateral vascular access, precontrast (A) CT images showed high-attenuation subperitoneal effusion (*) along the left iliac muscle, without active bleeding at CT-angiography (B), which was treated conservatively. C-F) In a 75-year-old woman with obliterating PAD, following PTA and stenting of the right superficial femoral artery via left CFA access, precontrast images (C, D) showed extensive, mass-like left retroperitoneal haematoma (*) with characteristic fluid-fluid levels (thin arrows), mild haemoperitoneum (+) in the pelvic cul-de-sac. CT angiography with maximum-intensity projection (MIP) images (E, F) showed extraluminal CM flowing from the site of arterial injury, indicative of active bleeding. Note displaced ipsilateral kidney. Emergency surgery including retroperitoneal decaillotage was required to seal the leaking femoral artery
