Summary
Aortic stent graft implantation, while less invasive, carries a risk of deterministic radiation effects. This study found 2.3% of patients received skin doses potentially causing harm, necessitating patient awareness and support.
Area of Science:
- Interventional Radiology
- Medical Physics
- Cardiovascular Surgery
Background:
- Endovascular stent graft implantation is an alternative to surgery for aortic pathology.
- Limited data exist on deterministic radiation effects during these procedures.
Purpose of the Study:
- To analyze radiation dosimetry during aortic stent graft implantation.
- To assess the risk of deterministic radiation effects in patients.
Main Methods:
- Retrospective analysis of 179 patients undergoing aortic stent graft implantation.
- Dosimetric data (kerma area product, cumulative dose) analyzed for 172 patients.
- Dosimetric films used to verify automated measurements and correct readings.
Main Results:
- Median dose area product was 153 Gy cm², median entrance skin dose was 0.44 Gy.
- Dosimetric quantities predicted skin dose effectively.
- 4 patients (2.3%) received potentially harmful skin doses.
Conclusions:
- Deterministic effects can occur even with well-trained staff during aortic stent graft procedures.
- Patients should be informed about potential skin injuries from high radiation doses.
- Adequate support systems are crucial for managing radiation-induced skin injuries.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
