[Transradial percutaneous approach for cardiac catheterization in patients with previous brachial artery cutdown].

The percutaneous punction of the radial artery for catheterization procedures has gained acceptance lately. This was a consequence of achieving results similar to the femoral approach, with the benefits of a lower rate of complications and increased comfort for the patients post procedure. Recently it has gained an additional impulse with the better prognosis obtained in acute coronary syndromes.

[Contrast induced nephropathy in acute coronary syndrome].

Contrast induced nephropathy (CIN) is one of the most frequent causes of acute renal failure in hospitalized patients. It is associated with an increase in morbidity and mortality in patients hospitalized for acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). Risk factors and prevention strategies are not well defined.

[Repeated radial artery puncture for cardiac catheterization].

Repeated radial artery puncture for cardiac catheterization. The radial artery approach for percutaneous cardiac interventions has gained worldwide acceptance due to the similar results obtained by the femoral artery access. In this paper, we report our experience with repeated puncture of the radial artery.
