✓ A case of coexisting proatlantal intersegmental artery and primitive trigeminal artery is described. These anomalies were incidental findings in a patient with hemiparesis due to occlusion of the middle cerebral artery. The primitive trigeminal artery had an asymptomatic aneurysm at its origin from the internal carotid artery.

✓ Experience with surgical clipping of 16 large and nine giant aneurysms of the intradural internal carotid artery (ICA) is described. Reconstruction of the parent artery with part of the aneurysmal wall was necessary in the majority of cases. Multiple clips were required for satisfactory clipping in 20 cases. Complications related to the clipping procedure comprised occlusion and stenosis of the parent carotid artery in isolated cases. Straightening of the parent carotid artery with consequent kinking of the middle cerebral artery was seen in three cases of an aneurysm with a dome directed ventrally in the proximal segment of the ICA. The factors that caused straightening of the ICA are analyzed. It was observed that an excessive change in the direction of the ICA can cause cerebral infarction.

✓ This report covers a series of four patients with acute cervical carotid occlusion and profound neurological deficits who were treated with intracranial intraarterial thrombolysis. All of the patients presented with arm plegia with variable leg involvement and two of them had global aphasia. Angiography identified occlusion of the proximal internal carotid artery (ICA) in each case and intracranial thromboembolus of the supraclinoid ICA and/or its branches. Catheter navigation through the occluded ICA segment was straightforward in three patients and somewhat difficult in one patient with an 80% ICA stenosis. Intraarterial urokinase infusion along with mechanical clot disruption was performed at the clot site in the middle cerebral artery, supraclinoid ICA, and/or anterior cerebral artery. All patients had recanalization of the treated artery after urokinase infusion. Antegrade flow through the ICA was reestablished in two patients, and good collateral filling across the anterior communicating artery was established in the other two. All patients had major pretreatment deficits (mean National Institutes of Health (NIH) Stroke Score 24 ± 4) with significant improvement noted at 3 months posttreatment (NIH Stroke Score 7 ± 6; p = 0.03). Two patients made a dramatic early recovery. Postprocedure computerized tomography revealed no abnormality in one and asymptomatic basal ganglia high density from repeated local contrast injections in two patients. On the basis of their findings in this small study group the authors suggest that catheter navigation through a presumably occluded carotid artery is feasible and possibly effective in thrombolytic therapy of intracranial thrombolysis. Further study with clinical trials is necessary to determine the safety and efficacy of this technique.

Temporary Occlusion

✓ Balloon test occlusion of the internal carotid artery (ICA) is useful in preoperatively assessing the risk of temporary occlusion or permanent sacrifice of the carotid artery. The incidence of symptomatic complications from this procedure is 1.7%. The case is reported of a 57-year-old woman in whom a balloon test occlusion of the left ICA was attempted. She developed a left ICA dissection/occlusion with subsequent embolization to the left middle cerebral artery, leading to right-sided hemiplegia and expressive aphasia. She was successfully treated by an emergency embolectomy followed by surgical repair of the left ICA, with an excellent outcome. This case represents the most serious complication encountered by the authors in more than 300 balloon test occlusions. Means of avoiding this complication during balloon test occlusion as well as the important factors in managing this problem are emphasized.

✓ 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.

✓ A case of giant traumatic false aneurysm of the intracranial internal carotid artery (ICA) with a concomitant carotid-cavernous fistula is reported. The fistula and the aneurysm persisted after ipsilateral cervical ICA ligation was performed elsewhere. Successful obliteration of the aneurysm and the fistula, with preservation of cross filling of the ipsilateral middle cerebral artery system, was accomplished by ligation of the intracranial ICA proximal to the origin of the posterior communicating artery with a 7–0 prolene suture, followed by transaneurysmal packing of the fistula.

Abstract OBJECTIVE AND IMPORTANCE A variant type of the primitive trigeminal artery (PTA) is a rare anomalous vessel that originates from the internal carotid artery and directly supplies the territory of the anteroinferior cerebellar artery and/or the superior cerebellar artery. We report a case of trigeminal neuralgia associated with this PTA variant, and we discuss the characteristics of this vessel. CLINICAL PRESENTATION A 51-year-old woman presented with a 10-year history of left paroxysmal facial pain. Magnetic resonance angiography and cerebral angiography demonstrated that an aberrant vessel originating from the left internal carotid artery directly supplied the cerebellum, without a basilar artery anastomosis. INTERVENTION Surgical exploration was performed via a left retrosigmoid approach. A loop of the aberrant vessel, which entered the posterior fossa through the isolated dural foramen, was compressing the trigeminal nerve. This aberrant vessel was displaced medially from the nerve with a prosthesis, with care to avoid kinking and avulsion of the perforating arteries. The patient's neuralgia resolved postoperatively. CONCLUSION Although the PTA variant is frequently associated with intracranial aneurysms, it is extremely rare for the variant to lead to trigeminal neuralgia. During microvascular decompression surgery, surgeons should be careful to prevent injury of the perforating arteries arising from the PTA variant.
