| Type | Description |
|---|---|
| Type A) | The OA arises from the anterior division of the IIA (most common). |
| Type B) | The OA arises from the IEA. |
| Type C) | The OA is a branch of the posterior division of the IIA. |
| Type D) | The OA arises from the IIA, above its final branching. |
| Type E) | The OA arises from the EIA. |
| Type F) | The OA arises from the femoral artery (least common). |
OA: obturator artery; IIA: internal iliac artery; IEA: inferior epigastric artery; EIA: external iliac artery.
