Coagulation of aneurysms by direct percutaneous thrombin injection
AJR. American Journal of Roentgenology
|August 1, 1986
Summary
A novel technique uses direct thrombin injection to effectively clot aneurysms. This minimally invasive approach showed no significant complications in four patients with various arterial aneurysms.
Area of Science:
- Vascular Surgery
- Interventional Radiology
Background:
- Aneurysms pose significant risks requiring effective treatment.
- Current treatments may involve complex surgical interventions.
Observation:
- A new method involves direct injection of diluted thrombin into aneurysms.
- Four patients with pseudoaneurysms (iliac, femoral, peroneal arteries) and one true aneurysm (accessory hepatic artery) were treated.
Findings:
- 500-1000 units of thrombin were injected into the aneurysmal sac.
- Injection was performed during blood stasis, either spontaneous or induced.
- No significant complications were observed in the treated patients.
Implications:
- Direct thrombin injection offers a promising, minimally invasive option for aneurysm treatment.
- This technique could potentially reduce the need for open surgery.
- Further research may validate this approach for a wider range of aneurysms.
