Key result
Transfemoral angiography is linked to non-puncture site platelet deposition in ~44% of patients.
Why the study?
The incidence and distribution of thromboembolitic events following transfemoral angiography were not well characterized using indium-111 labeled platelets.
What is the incidence and location of platelet deposition in patients undergoing transfemoral angiography?
Comparison
Platelet deposition sites before and after angiography
Design
Observational study using indium-111 labeled autologous platelets and gamma camera imaging
Follow-up
1-2 days

Subclinical platelet deposition may occur during angiography; hypothesis-generating for indium-111 imaging in thromboembolic risk assessment.
Observational (n=27)
What is the incidence and location of platelet deposition in patients undergoing transfemoral angiography?
Transfemoral angiography frequently causes subclinical platelet deposition along the catheter path and at the puncture site, highlighting the potential need for improved catheter materials or antithrombotic therapy.
O’Connor et al. (1986) conducted an observational in Patients undergoing transfemoral angiography (n=27). Transfemoral angiography was evaluated on Platelet deposition at sites other than the puncture site. Transfemoral angiography resulted in indium-111 labeled platelet deposition at sites other than the puncture site in 44% of patients.
