Abstract
INTRODUCTION AND IMPORTANCE: Pseudoaneurysms are abnormal arterial dilations that pose a significant risk of rupture, often arising from trauma or iatrogenic interventions. Endovascular embolization using coils is the preferred treatment; however, its high cost and limited availability in certain healthcare settings can hinder optimal management. This report explores the adjunctive use of guidewire-derived coils as a cost-effective solution for pseudoaneurysm embolization, particularly in resource-limited settings where conventional coils alone may be insufficient to achieve complete occlusion. CASE PRESENTATION: We describe three patients with arterial pseudoaneurysms who were successfully treated using guidewire-derived coils alongside conventional coil embolization. Patient 1: A 53-year-old male with a pseudoaneurysm in the right inferior gluteal artery. Patient 2: A 30-year-old male with a traumatic pseudoaneurysm of the left axillary artery. Patient 3: A 28-year-old pregnant female with a pseudoaneurysm in the uterine branch of the right internal iliac artery. In all cases, conventional coil embolization was initially performed but remained incomplete due to limited availability of additional coils. Guidewire-derived coils were then utilized as an adjunctive embolic agent, successfully achieving complete occlusion of the pseudoaneurysms and yielding favorable clinical outcomes. CLINICAL DISCUSSION: Endovascular coil embolization is a standard treatment for pseudoaneurysms, but financial and logistical constraints can limit access to commercial coils. Guidewire-derived coils, previously reported as an alternative, proved feasible, safe, and effective adjunct to the conventional coils in our cases. This approach broadens therapeutic options in resource-limited settings by reducing dependence on costly commercial coils. CONCLUSION: Guidewire-derived coils offer a cost-effective adjunct for pseudoaneurysm embolization, providing a practical solution in settings where standard coils are limited or unavailable.
