An iatrogenic internal carotid artery (ICA) pseudoaneurysm is an extremely rare complication of cervical spine surgery. Here we report an extraordinary case of massive hematemesis due to a ruptured ICA pseudoaneurysm caused by the laminoplasty plate 10 years after cervical spine surgery. Computed tomography angiography revealed a ruptured 4×10-mm left extracranial ICA pseudoaneurysm probably connected to the pharynx. Emergent surgery was performed because of the uncontrolled massive bleeding. After complete resection of the injured segment, an interposition graft with a 6-mm polytetrafluoroethylene graft was placed and the fistula tract to the pharynx was repaired.

The rupture of a popliteal artery aneurysm is very rare, and can lead to serious complications if untreated. Any reports of a huge pseudoaneurysm, following rupture of the popliteal artery aneurysm could not be found in a review of the literature. A pulsatile huge mass leading to a deep venous thrombosis, was observed in a 74 years old male patient who for 2 months had had a progressively swollen and painful left leg. On angiographic evaluation, the mass was found to be a pseudoaneurysm originating from a ruptured true aneurysm of the popliteal artery. There was also a small true aneurysm in the contralateral extremity at the same localization. Both the false, and true aneurysms were resected surgically and arterial continuity was established with a synthetic polytetrafluoroethylene graft.
