Implication

Rare spontaneous collaterals may preserve perfusion in chronic iliac occlusion; hypothesis-generating for mechanisms and prevalence.

Key Points

To describe a rare presentation of spontaneous collateral vessel formation bridging the left internal mammary artery to the left common iliac artery in a patient with chronic vascular occlusion.
Invasive diagnostic angiography performed on a 57-year-old female presenting with suspected subacute myocardial infarction.
Angiographic assessment of systemic and pelvic collateral blood pathways following the discovery of chronic arterial occlusion.
Angiography confirmed an extensive spontaneous collateral network originating from the left internal mammary artery and reconstituting the chronically occluded left common iliac artery.
The compensatory collateral circulation maintained adequate distal perfusion to the lower extremity despite long-standing complete pelvic arterial obstruction.

Population

1 57-year-old female patient referred for invasive diagnostics with urgent suspicion of subacute myocardial infarction as the first manifestation of coronary heart disease and chronic occlusion

Outcome

Spontaneous collateral formation of the left mammary artery to the left common iliac artery
