A 42-year-old female patient, who had been diagnosed with an occlusion of her left internal carotid artery (ICA) following Doppler ultrasonographic (US) and digitally-subtracted angiographic (DSA) examinations performed in an outer healthcare center in order to eliminate the underlying cause of her complaint of amorosis fugax, later applied to our hospital with the same complaint. At Doppler US performed in our hospital’s radiology department, her right common carotid artery (CCA) was normal, but her left CCA was hypoplastic. The right internal artery (ICA) was validated as normal. At the left side, however, the ICA was apparent only as a stump and it did not demonstrate a continuity. The diagnosis of ICA agenesis was confirmed by the utilization of Doppler US, CT, and DSA imaging, and it was concluded also that ipsilateral CCA hypoplasia could be evaluated as an important clue to the diagnosis of ICA agenesis.

✓ A 54-year-old woman was admitted with a complete occlusion of the right internal carotid artery and a 25% stenosis of the left internal carotid artery. Intracranial circulation on the right side was restored by taking a vein from the leg and anastomosing the vein of the intracranial carotid artery just distal to the anterior clinoid process. Prior to insertion the vein was turned inside out, the valves removed and then reinverted allowing the distal end of the vein to be anastomosed to the intracranial internal carotid artery. The blood flow was therefore reversed in the vein. The proximal end of the vein was anastomosed to the common carotid artery. Upon completion there was excellent circulation in the bypass graft and internal carotid artery.

Abstract The study of CT angiographies performed on a CT scanner GE LightSpeed VCT16 Slice CT revealed some morphological features of the ophthalmic artery related to origin, morphometry and the internal carotid arteries in the vicinity of this artery. The diameter of the left internal carotid artery under the origin of the ophthalmic artery was between 4.0-5.8 mm and that of the right ophthalmic artery at the same level was between 4.1-5.3 mm. Under the origin of the ophthalmic artery, the internal carotid arteries were larger in diameter on the leftside in 80% of cases, with differences of 0.1-0.3 mm, and on the right side these differences were between 0.1-0.2 mm, 20% of cases. The diameter of the left internal carotid artery above the origin of the ophthalmic artery was 3.7-5.0 mm, and the origin of the right carotid artery at the same level was 3.8-5.0 mm.

A mature specimen of the Australian cassowary (Casuarius australis Wallace) was dissected and a diagram of the main arteries in the neck region prepared. In the arrangement and distribution of these arteries, the cassowary differs from other species of birds previously studied. The left radix aortae and left ductus Botalli remain as a ligamentous vestige, the ligamentum aortae. The left internal carotid artery alone enters the hypapophysial canal. The right internal carotid artery is lacking or has become modified to form the ascending oesophageal artery of the adult, in the basal portion of the neck. The pattern of the arrangement of the main arteries in the neck and thorax shows a relatively primitive avian condition.

Background: We present a rare case of a left-sided carotid cavernous fistula (CCF) that presented 15 months post initial trauma with right-sided ophthalmic signs and symptoms. Highlighted is a contralateral endovascular approach to treating this traumatic CCF. Methods: Described is a case of a left-sided CCF caused by a self-inflicted gun shot wound to the head that was initially treated conservatively by neurosurgery and opthomology. The patient presented 15 months later with headache, acute right-sided periorbital swelling, severe right eye and facial pain. Results: Angiography confirmed the presence of a left-sided CCF with preferential drainage into the right cavernous sinus and right superior ophthalmic vein. The left internal carotid artery (ICA) was shown to be narrow and irregular. Multiple attempts to navigate the micro catheter through the vessel were unsuccessful. Instead, the fistula was embolized using a contralateral approach through the right internal carotid artery and across the anterior communicating artery. Imaging post-operatively confirmed successful occlusion of the CCF. Conclusions: This case is a rare example of a left-sided ICA occlusion secondary to trauma presenting 15 months after the initial injury with right-sided ophthalmic signs and symptoms. It is also one of only a few in the literature that describe successful treatment of traumatic CCF through a contralateral approach.

Supraclinoid Internal Carotid Artery

✓ The case of an aneurysm occurring at the site of fenestration of the supraclinoid portion of the left internal carotid artery (ICA) is reported. A 37-year-old woman presenting with subarachnoid hemorrhage was found to have bilateral ICA aneurysms at the level of the posterior communicating arteries (PCoA's). The patient underwent right-sided craniotomy with uneventful clipping of the right PCoA aneurysm, and attempted clip placement on the contralateral left ICA aneurysm. The follow-up angiogram revealed a residual dome on the left ICA aneurysm, which was noted to originate at the proximal end of a fenestration of the left supraclinoid ICA. This represents the third reported case of fenestration of the intracranial ICA associated with an aneurysm. Intracranial artery fenestrations and their embryological origins are also reviewed.

Limb Shaking

Nasopharyngeal carcinoma (NPC) is commonly treated with bilateral neck radiation, which is closely associated with the complication of carotid-occlusive disease. This leads to cerebral hemodynamic compromise and possible ischemic stroke. Another manifestation is limb-shaking transient ischemic attacks (LS-TIAs), characterized by rhythmic jerks which can be easily mistaken as a focal motor seizure. We describe a case of unilateral LS-TIAs from bilateral carotid occlusion that resolved with contralateral carotid revascularization. Our patient is a 65-year-old gentleman who had no significant co-morbidities other than a past history of bilateral neck irradiation for NPC 8 years before. He presented with left-sided limb weakness and subsequently left-sided limb involuntary movements whenever he sat up or stood. His symptoms did not respond to anti-epileptic therapy. Clinical and neurological examination was significant for a left pronator drift and weak left finger abduction. Computed tomography and magnetic resonance imaging of the brain revealed infarcts in the right periventricular and watershed areas; MR angiogram showed bilateral internal carotid artery occlusion. Single photon emission computed tomography showed reduced blood flow in the right frontal, temporal, and parietal regions, that reduced further after acetazolamide challenge. He was diagnosed as having LS-TIA secondary to carotid-occlusive disease. Attempts at endovascular opening the right internal carotid artery failed. Following successful left carotid angioplasty and stenting, his symptoms gradually resolved. The left internal carotid artery remained patent at the 3-month follow-up; the right side remained occluded. Our case supports the hypothesis that LS-TIAs are due to hemodynamic compromise and may respond to improved collateral cerebral blood flow.
