Aneurysm & Pseudoaneurysm Embolization

Aneurysm and pseudoaneurysm embolization includes minimally invasive, image-guided procedures used to treat abnormal dilatations or defects in blood vessels. These interventions are performed to prevent rupture, control bleeding, or manage vascular complications based on imaging and clinical assessment.

Overview

Aneurysms and pseudoaneurysms can occur in visceral, peripheral, or central arteries due to degenerative changes, trauma, infection, or iatrogenic injury. Pseudoaneurysms differ from true aneurysms in that they involve a breach in the vessel wall rather than uniform dilation.

Embolization techniques allow targeted exclusion of the abnormal vessel segment while preserving blood flow to surrounding tissues, avoiding open surgery in appropriately selected patients.

Clinical Indications

Aneurysm and pseudoaneurysm embolization may be considered in patients with:

Visceral arterial aneurysms
Peripheral arterial aneurysms
Pseudoaneurysms following trauma or procedures
Vascular bleeding related to aneurysmal rupture
Incidental aneurysms with risk of progression

Iatrogenic vascular injuries

Procedures Performed

Embolization of visceral arterial aneurysms
Embolization of peripheral arterial aneurysms
Pseudoaneurysm embolization using image guidance
Coil, plug, or liquid embolic techniques
Image-guided management of aneurysm-related bleeding
Diagnostic angiography for vascular mapping

Role of Interventional Radiology

Interventional radiology provides precise access to affected blood vessels using real-time imaging guidance. Embolization is performed through small vascular access points, allowing targeted treatment of aneurysms and pseudoaneurysms with minimal disruption to surrounding structures.

These techniques are often used as alternatives to open surgery or in patients where surgical risk is high.

Approach and Patient Care

Each case is evaluated with detailed imaging to assess aneurysm size, location, and vascular anatomy. Treatment planning is individualized, considering patient stability, risk of rupture, and associated medical conditions.

Patients are monitored before and after the procedure to ensure procedural safety and appropriate post-intervention care.

Frequently Asked Questions

What is the difference between an aneurysm and a pseudoaneurysm?

An aneurysm involves dilation of all layers of the vessel wall, while a pseudoaneurysm results from a defect in the vessel wall with blood contained by surrounding tissue.

When is embolization recommended?

Embolization is considered when imaging shows an aneurysm or pseudoaneurysm that carries a risk of rupture or bleeding.

Is embolization an alternative to surgery?

In selected patients, embolization may be used instead of or in addition to surgical treatment.

Is hospitalization required after embolization?

Hospital stay depends on the procedure performed and the patient’s overall condition.
