Does diabetes protect the femoral artery against atherosclerosis?

Aim: To compare the extent of angiographically detected stenoses in different segments of the lower leg arteries in diabetics and nondiabetics.

Methods: The study group consisted of 60 nondiabetic and 38 diabetic patients with lower extremity disease and no previous vascular interventions. Arterial lesions were analysed by digital subtraction angiography (DSA).

The radial artery is larger than the ulnar.

Background: The radial artery is presently widely used as a bypass graft for coronary artery reconstruction. However, the traditional opinion that the ulnar artery is the larger forearm artery has been questioned.

Methods: The internal diameters of the radial and ulnar arteries were measured at the wrist in postmortem angiograms of 24 cadavers.

Imaging of experimental end-to-side anastomoses in a cast model.

Objective: To evaluate cast models in the imaging of experimental end-to-side anastomoses.

Design: Experimental study.

Setting: Teaching hospital, Finland.

Carotid stenosis and abdominal aortic aneurysm at the follow-up examination in patients treated for acute extremity ischaemia.

Background: To evaluate survivors treated for acute extremity ischaemia as a risk-group for carotid stenosis and abdominal aortic aneurysm at the follow-up examination.

Experimental Design: Clinical study with median follow-up of 14 (8-32) months.

Setting: Central Hospital of Central Finland.

DNA flow cytometry in surgically treated lung cancer--prognostic significance.

Although DNA aneuploidy and high proliferative activity (S-phase fraction, SPF) of tumour cells, measured by flow cytometry, have proved to be indicators of poor prognosis in most solid tumours, there have been conflicting results in lung cancer studies. During a four-year period we studied the prognostic significance of DNA ploidy and SPF in 99 surgically treated lung cancer patients. Flow cytometric analysis was done from archival, formalin-fixed, paraffin-embedded tumour specimens.
