Ultrasound guidance for urgent arterial and venous catheterisation: randomised controlled study.

Background: Haemodynamically unstable patients often require arterial and venous catheter insertion urgently. We hypothesised that ultrasound-guided arterial and venous catheterisation would reduce mechanical complications.

Methods: We performed a prospective RCT, where patients requiring both urgent arterial and venous femoral catheterisation were randomised to either ultrasound-guided or landmark-guided catheterisation.

A Thrombosed Popliteal Aneurysm Ruptured in the Setting of Chronic Limb Ischemia: A Rare Complication that Can Occur at Long Term.

Rupture of a chronic thrombosed or excluded popliteal arterial aneurysm is rare, but has been previously reported in the literature. The management of a ruptured thrombosed popliteal aneurysm, in a context of chronic limb ischemia, raises the problem of latent ischemia and its outcome. In this case report, we present the first case of a ruptured thrombosed popliteal aneurysm in a patient presenting chronic ischemia.
