Coronary arteriography: prevention of thromboembolic complications using a pressure-drip flushing technique
Insights
Modifying percutaneous femoral artery puncture techniques significantly reduced mortality and morbidity in coronary arteriography. The new pressure-drip flushing method lowered complication rates, especially thromboembolic events.
Area of Science:
- Cardiology
- Interventional Radiology
- Medical Device Technology
Background:
- Coronary arteriography is a crucial diagnostic tool.
- Traditional techniques like Sones (brachial cutdown) and Judkins (percutaneous femoral puncture) have associated risks.
- Thromboembolic complications are a significant concern in these procedures.
Purpose of the Study:
- To evaluate the impact of modified percutaneous femoral artery puncture techniques on mortality and morbidity.
- To compare complication rates between classic and modified coronary arteriography methods.
- To assess the effectiveness of a pressure-drip flushing technique.
Main Methods:
- Analysis of 1,833 selective coronary arteriograms performed between 1970 and 1974.
- Comparison of outcomes using classic brachial arteriotomy and percutaneous femoral puncture versus modified techniques with pressure-drip flushing.
- Categorization of complications into mortality and morbidity, specifically noting thromboembolic events.
Main Results:
- Overall mortality decreased from 1.01% (589 patients) to 0.16% (1,244 patients) after introducing the pressure-drip flushing technique.
- Morbidity incidence dropped from 3.0% (18/589) to 1.2% (total), with significant reductions in percutaneous femoral puncture complications.
- Modified percutaneous techniques showed a marked decrease in thromboembolic complications, while local arteriotomy complications remained similar.
Conclusions:
- Modification of percutaneous femoral artery puncture techniques, particularly with pressure-drip flushing, substantially reduces mortality and morbidity.
- The pressure-drip flushing technique is highly effective in mitigating thromboembolic complications associated with coronary arteriography.
- These advancements represent a significant improvement in the safety profile of coronary arteriography procedures.
Abstract:
All selective coronary arteriographic examinations (1,833) performed in the authors' laboratory during a five-year period (1/1/70 to 12/31/74) were analyzed for mortality and total morbidity according to method used. During the first two years, the control period, the classic brachial artery cutdown (Sones) and percutaneous femoral artery puncture (Judkins) techniques were utilized. Mortality rate for the total 589 patients was 1.01%. This included a mortality of 0.26% (1/386) for the brachial arteriotomy method, and 2.5% (5/203) for the percutaneous femoral puncture approach. After introduction of the pressure-drip flushing technique, the subsequent three-year mortality rate for a total of 1,244 patients was 0.16%. This included an incidence of 0.17% (1/585) for brachial arteriotomy and 0.15% (1/659) for modified percutaneous puncture techniques. The morbidity incidence during the initial two-year period was 3.0% (18/589). This included an incidence of 2.0% for brachial arteriotomy and 5.0% for percutaneous puncture techniques. After institution of the new pressure-drip flushing technique the total incidence fell to 1.2% equally divided between arteriotomy and percutaneous techniques. Modification of the classic percutaneous femoral artery puncture techniques has resulted in major reduction of mortality and morbidity complications which are chiefly thromboembolic in nature. It has not significantly influenced local thrombotic complications of arteriotomy.
