Complications of percutaneous transfemoral coronary arteriography
Insights
Selective coronary angiography complications significantly decreased over six years. Improved techniques reduced myocardial infarctions, cerebral vascular accidents, and femoral thrombosis, enhancing patient safety in cardiac procedures.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Surgery
Background:
- Coronary angiography is a crucial diagnostic procedure.
- Judkin's technique is a common method for selective coronary angiography.
- Complications associated with coronary angiography necessitate ongoing safety improvements.
Purpose of the Study:
- To analyze complication rates following selective coronary angiography using Judkin's technique.
- To identify trends in major complications including death, myocardial infarction, cerebral vascular accidents, and femoral thrombosis.
- To evaluate the impact of procedural refinements on patient safety over a six-year period.
Main Methods:
- Retrospective analysis of complication statistics from 1625 patients.
- Data collected over a six-year period (1967-1973).
- Categorization of complications into death, myocardial infarction, cerebral vascular accidents, and femoral thrombosis.
Main Results:
- Overall complications decreased significantly over the study period.
- Myocardial infarctions reduced from 2.4% to 0.44%.
- Cerebral vascular accidents and femoral thrombosis decreased to zero in the final year.
- Death rate remained stable between 0.3% and 0.6%.
Conclusions:
- Procedural modifications, including catheter flushing, guidewire techniques, pressure monitoring, and careful patient assessment, have substantially reduced major complications in selective coronary angiography.
- These improvements enhance patient safety without significantly altering the mortality rate.
- Judkin's technique, with refined methods, remains a safe and effective procedure for coronary angiography.
Abstract:
Complications statistics in 1625 patients undergoing selective coronary angiography by Judkin's technique have been analysed for four major areas-death, myocardial infarction, cerebral vascular accidents, and femoral thrombosis. Over a six-year period, considerable decrease in the number of complications has occurred. Myocardial infarctions have decreased from 2.4% (1967-71) to 0.44% (1973), an improvement related to careful catheter flushing, guidewire insertion technique and careful pressure monitoring within the coronary arteries. Cerebral accidents have decreased from a maximum of 1.3% (1972) to none (1973). This is also related to catheter guidewire techniques, and to avoidance of entering the cerebral vessels inadvertently when crossing the aortic arch with the coronary catheter. Femoral artery thromboses have decreased from 2.7% (1967-71) to none (1973). This is due to monitoring the dorsalis pedis pulse when compressing the femoral artery and avoiding complete femoral arterial obstruction with the associated lack of flow ultimately leading to thrombosis. Death rate has remained essentially unchanged (0.3-0.6%).
