Complications of angiography in children and means of prevention
Insights
Thromboembolic complications in pediatric angiography decreased significantly with technical advances. No complications occurred in the final 153 cases, highlighting improved safety in pediatric interventional procedures.
Area of Science:
- Pediatric cardiology
- Interventional radiology
- Vascular medicine
Background:
- Thromboembolic complications are a risk in pediatric angiography.
- Understanding thrombus origin is key to reducing complications.
Purpose of the Study:
- To evaluate the incidence of thromboembolic complications in pediatric angiography.
- To assess the impact of technical advancements on complication rates.
Main Methods:
- Retrospective analysis of 267 consecutive angiographic examinations in children.
- Categorization of complications based on procedural approach (surgical vs. percutaneous).
Main Results:
- 14 thromboembolic complications occurred in 267 examinations.
- 8 complications (57%) followed surgical exposure (14 cases), while 6 (2.4%) followed percutaneous angiography (253 cases).
- No complications occurred in the last 153 examinations, following implementation of technical improvements.
Conclusions:
- Technical advancements, including thin-walled catheters and heparinization, significantly reduced thromboembolic complications in pediatric angiography.
- Percutaneous angiography is associated with a lower complication rate than surgical exposure.
- Continuous improvement in techniques has made pediatric angiography safer.
Abstract:
In 267 consecutive angiographic examinations in children 14 thromboembolic complications occurred: following surgical exposure 8 complications in 14 cases and 6 complications in 253 percutaneous angiographies. The origin of thrombus during angiography has recently been clarified. Technical advances such as thin walled catheters, systemic heparinization and lately heparinized catheters decreased the complication rate significantly, no complication occurred among the last 153 examinations.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Imaging Studies for Cardiovascular System III: X-Ray
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
