✓ Intracranial anastomosis between the distal anterior cerebral arteries (ACA's) was performed on two patients. One patient had isolated occlusion of the proximal ACA on one side causing monoparesis in the leg, and the other patient suffered from occlusion of the internal carotid artery and a small anterior communicating artery. The weakness of the legs improved immediately after surgery and cerebral angiography revealed a good filling of the bilateral ACA's. Technical aspects and indications for the procedure are discussed.

Fine Print

✓ The angiographic and anatomical features of an anomalous communication between the intradural internal carotid artery and the anterior cerebral artery are described. Essential features of the anastomosis include an origin at, or close to, the origin of the ophthalmic artery, a course ventral to the ipsilateral optic nerve and anterior to the optic chiasm, and a termination near the anterior communicating artery. Although rare, the condition should be considered as an entity. The incidence of associated berry aneurysm and other congenital vascular anomalies is high.

✓ Six patients with intracranial mycotic aneurysms of extravascular origin are reported. Four had aneurysms of the intracavernous portion of the internal carotid artery associated with thrombophlebitis of the cavernous sinus, and two had aneurysms of the cerebral arteries associated with meningitis. An aneurysm of this type may rupture, producing subarachnoid hemorrhage, or it may become thrombosed and decrease in size or spontaneously disappear. In some patients it may persist and develop calcification in the wall.

✓ Saccular cerebral aneurysms were successfully induced in two monkeys treated with ligation of the common carotid artery, experimental hypertension, and β-aminopropionitrile feeding. The cerebral aneurysms developed on the large arteries at the base of the brain, such as the anterior communicating artery and the internal carotid artery at the origin of the posterior communicating artery. Because of the similarity of the monkey to man as a species, the present results strongly suggest the significance of postnatal aggravating factors in the development of cerebral aneurysms in man.

✓ The effect of removal of the left superior cervical ganglion on the contractile response to norepinephrine (NE) and 5-hydroxytryptamine (5-HT, serotonin) was studied in isolated segments of the middle cerebral artery (MCA) and posterior communicating artery (PCoA) of the cat. Fifteen days after the excision, each dose of NE elicited a potentiated response in both the MCA and the PCoA, whichever side they originated. By contrast, 5-HT induced enhanced vasoconstriction at each dose only in the MCA and PCoA from the left side. When segments of MCA and PCoA from the right side were challenged against 5-HT, a significantly increased response was found only at the first three doses. On the other hand, the NE content of pools made of MCA, PCoA, and anterior cerebral artery from each side was reduced to the same level on both sides after ganglion removal. These results indicate that the excised superior cervical ganglion innervated the MCA and PCoA from both sides of the circle of Willis.

✓ A ruptured anterior cerebral artery (ACA) aneurysm is reported in a patient in whom an anomalous ACA arose from the internal carotid artery at the bifurcation. The aberrant artery coursed anteriorly along the ipsilateral olfactory tract and made a hairpin turn posterior to the olfactory bulb, supplying the circulation of the ACA. Persistence of the primitive olfactory artery is suggested as an embryological origin of this vascular anomaly.

Endovascular Approach

✓ Cavernous internal carotid artery (ICA)—anterior cerebral artery (ACA) anastomoses are unusual anomalies in which a duplicated A1 segment of the ACA arises from the infraoptic ICA. The authors report on a 30-year-old woman who presented with subarachnoid hemorrhage from an anterior communicating artery (ACoA) aneurysm associated with an extremely rare variant of this anastomosis. The extra A1 segment emerged from the ICA within the cavernous sinus rather than at or above the level of the ophthalmic artery. The presence of the anomalous vessel provided a straightforward endovascular approach to the ACoA and allowed the use of coil placement rather than surgical clipping to treat the aneurysm successfully.

✓ A 17-year-old girl died from the rupture of a large fusiform aneurysm of the terminal internal carotid artery. Autopsy revealed three other fusiform aneurysms originating from major cerebral arteries clearly within the ports of previously administered telecobalt radiation therapy. Five years prior to her death, a suprasellar germinoma was partially removed and the area was treated by radiation therapy via three ports. The original arteriograms showed a normal vascular tree. Repeat arteriograms, 3 years and 8 months before her death, demonstrated the aneurysms. The development of aneurysms following radiation damage of the arteries has been reported previously, but not in intracranial vessels.

Anomalous Branch

✓ Angiographic and operative investigations revealed an anomalous branch of the internal carotid artery (ICA) in a patient with an anterior communicating artery (ACoA) aneurysm. The anomalous vessel originated from the right ICA at the level of the ophthalmic artery, and pursued an infraoptic and prechiasmatic path to supply both pericallosal arteries. The clinical features and possible genesis of this anomaly are discussed. This irregularity is frequently associated with intracranial aneurysms, especially those of the ACoA, and with other anomalies.
