A proximal occluded vertebral artery (VA) with reconstitution by muscular collateral vessels is a relatively common finding. However, due to inadequate intracranial anastomosis and hypoplasia or stenosis of the opposite VA, a number of patients develop symptoms of brain ischemia. In the current case, a 63-year-old man presented with repeat neurological symptoms such as dizziness, nausea, vomiting, dysarthria, left hemiparesis, and right hemianopsia. Magnetic resonance imaging revealed multiple posterior infarctions. Angiography revealed the VA to be occluded and reconstituted by collateral vessels. Considering the above results, we performed vertebral carotid artery transposition. However, several technical difficulties were encountered due to space limitations in the operative field and the limited length of the vessels to be anastomosed. To overcome such situations, we introduced a modified posterior wall end-to-side anastomosis technique.

Unusual presentations of Giant Cell Arteritis (GCA) can sometimes delay the diagnosis and its prompt treatment. An 83-year-old male patient was admitted in the emergency department with a few hours evolution of tongue swelling, dysphagia and dysarthria. He also complained of a bitemporal headache with about 4 months of evolution and resistant to all treatment prescribed, including ergotamine, that he had started one week before. Upon examination, the patient presented a bilateral temporal pain and reduced mobility of the tongue which evolved to complete cyanosis. The blood tests revealed normocytic normochromic anaemia, an erythrocyte sedimentation rate of 62 mm/h, and C-reactive protein of 23,6 mg/dl. Cranial CT scan was normal and the cervical CT angiogram showed reduced vascularization of the left submandibular gland and of the base of the tongue. The cervical doppler ultrasound was compatible with arterial inflammation. Given the high suspicion of GCA, the patient was immediately put on a high dose of corticosteroid, resulting in a big improvement of the symptoms, which continued in the following weeks. In conclusion, the clinical suspicion of GCA is fundamental for an early diagnosis. The authors consider that ergotamine might have triggered tongue ischemia in this case.

Head and neck injuries are common and can be associated with cervical vessel injury. In some cases, the cor-rect diagnosis of artery dissection can be a real challenge given the nonspecific signs. We present the case of a spinal cord-injured patient with neurological sequelae and delayed posterior circu-la-tion stroke caused by bilateral vertebral artery dissection. The signs of cerebellar and occipital lobe ischemia were masked by manifestations of spinal cord injury. The patient was unconscious and in a serious condition, but, despite no proper stroke treatment, only residual dysarthria and upper limb ataxia were seen after reha-bilitation. Any clinical suspicion based on the combination of head or neck trauma with atypical or evolving neuro-logical symptoms should be verified for the possibility of a vertebral artery dissection.
