Sudden supraclavicular pain is often associated with myocardial infarction but seldom due to a rupture of V1-segment vertebral artery aneurysm. A ruptured V1 segment of vertebral artery dissecting aneurysm making a fistula with the adjacent vein has rarely been described in literature. Here we present a case of a 29-year-old healthy woman with sudden supraclavicular pain and palpable mass that developed after pain. Initial ultrasound showed suspicion of large haematoma. CT angiogram showed a left-sided dissecting V1-segment vertebral artery ruptured aneurysm. Angiography showed an additional fistula between the aneurysm and the adjacent vein. The patient was treated successfully with coil embolisation. The vertebral artery occlusion was well tolerated without any complications. Endovascular coiling is a fast and effective treatment modality. However, a parent vessel occlusion can be sometimes dangerous if the contralateral vertebral artery supply is not sufficient. Surgical possibilities to reconstruct the parent vessel should also be considered in complex cases.
