ABSTRACT: Introduction:
Pseudoaneurysm is a dilatation of an artery with actual disruption of one or
more layers of its wall, rather than just expansion of wall layers.
Pseudoaneurysms are common vascular abnormalities. Computed Tomography (CT),
Magnetic Resonance Imaging (MRI), sonography, and angiography all are valuable
modalities in the imaging workup of pseudoaneurysms. Conventional angiography
remains the gold standard for diagnosis. Therapeutic options have evolved in
recent years from the traditional surgical option toward a less invasive
approach which includes procedures such as Ultrasound (US)-guided compression, US-guided
percutaneous thrombin injection, and endovascular management (embolization,
stent-graft placement and endovascular coiling). Objective: In this article, we
discuss pseudoaneurysms of various arteries, and available percutaneous and
endovascular treatment options. Materials and Methods: Sixteen patients diagnosed
with pseudoaneurysm involving visceral and peripheral arteries were included in
this study. The initial diagnosis was made with CDUS, CECT, and CTA followed by catheter angiogram for
therapeutic procedures. Results: All the 16 patients with pseudoaneurysms were
successfully treated with endovascular and percutaneous embolization to achieve
stasis. Conclusion: CT, MRI, sonography, and angiography may all be valuable in
the imaging workup of pseudoaneurysms. The use of minimally invasive treatment
has led to a marked decrease in the morbidity and mortality rates for
pseudoaneurysms.
