Introduction: The use of percutaneous coronary intervention (PCI) to treat coronary artery disease (CAD) has expanded with PCI being the preferred revascularization method. Data regarding intra-procedural changes to peripheral perfusion are limited. With this increasing trend of trans-radial procedures, recognition of risks for complications is important.
Method: This was a cross-sectional study including patients 30 years and older, have a negative Allen's test, undergoing coronary angiography or PCI, via the trans-radial approach. Pulse wave oximetry was done on the involved arm during the procedure and data was recorded as wave form changes and saturation readings.
Result: A total of 99 patients undergoing coronary angiography or PCI were included in the study. A decrease in peripheral perfusion was observed in 4 subjects and a decrease in peripheral oxygenation was observed in only 2 subjects, all of whom underwent coronary angiography. No statistically significant difference was noted between the two groups in all parameters. Only 1 patient presented with decrease in both peripheral pressure and oxygen saturation.
Conclusion: In those undergoing trans-radial coronary angiography or PCI, there are no predictive factors that determine decrease in peripheral perfusion or oxygen saturation. Patients with a normal Allen's test have a low occurrence of clinical sequelae after radial artery occlusion
