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.

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.

Internal Carotid Arteries

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.

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.

Abstract We report the case of a patient with a large left subfrontal arteriovenous malformation (AVM) that was supplied by the right internal carotid artery. The anomalous blood supply developed because of complete occlusion of the left internal carotid artery. When the AVM was removed, the patient experienced a hemorrhage into the right basal ganglia. The possibility that this hemorrhage was related to a defect of autoregulation in blood vessels that lie proximal to a large AVM is discussed. Even though this is a unique case, the pathophysiological events that are documented are relevent to the preoperative preparation and surgical management of all patients with AVMs.

Transvenous Approach

Introduction. Dural carotid cavernous fistula is acquired, relatively rare, condition comprising of numerous smallcaliber meningeal arterial branches, draining directly into cavernous sinus. Endovascular therapy is the treatment of choice, preferably by a transvenous approach. In the case of inaccessible inferior petrosal sinus, other alternative routes are considered. We presented a case of dural carotid cavernous fistula completely occluded with Guglielmi detachable coils, using a transvenous approach through facial and superior ophthalmic vein. Case report. A 62-year-old man was referred with a gradual worsening proptosis, red eye, and decreased visual acuity, on the right side. Digital subtraction angiography revealed the presence of a right dural carotid cavernous fistula, predominantly supplied from dural branches of the right internal carotid artery siphon, with minimal contribution from the right middle meningeal artery and contralateral dural branches of the left internal carotid artery siphon. The fistula was drainaged through the dilated superior ophthalmic vein, and via the facial to the internal jugular vein. There was neither pacification of pterygoid and petrous sinuses, nor cortical venous reflux. Endovascular treatment was performed by a transvenous approach. A guiding catheter was placed in the right facial vein. A microcatheter was advanced through the dilated angular and superior ophthalmic vein, and its tip positioned into the right cavernous sinus. Coils were deployed, until a complete angiographic occlusion of the fistula had been achieved. The patient experienced rapid improvement in the symptoms, with complete normalization of his condition one month after the treatment. Conclusion. Coil embolization of dural carotid cavernous fistula by transvenous catheterization, through the facial and superior ophthalmic vein, can be considered as safe and effective treatment option in the presence of marked anterior drainage.
