Twenty-three cases of arterial injury after 8,208 arterial catheterizations for diagnostic or therapeutic indications at Glasgow Royal Infirmary are reviewed. Clinical presentation included haematoma formation, development of an acutely ischaemic limb or a false aneurysm. Patients with valvular heart disease are identified as a high risk group.

Arterial thrombus formation during clinical percutaneous catheterization.

Deposition of thrombotic material on catheters was observed following more than 50% of 93 diagnostic catheterizations. The incidence of deposition of thrombotic material on catheters remaining in the body for more than 1 day was 100%. Polyethylene and siliconized polyurethane catheters were less thrombogenic than Teflon end-occluded catheters. A definite time relationship between the thrombus f...

Percutaneous arterial catheterization for multiple sampling.

A modified technique for umbilical arterial catheterization.

A modified technique for umbilical artery catheterization was assessed in babies in whom conventional method failed or if the cord was dry. Success rate attained with the modified technique was 90% (19/21). This modified technique could provide an easier and faster method for successful umbilical arterial catheterization.
