The Third

Partial oculosympathetic palsy followed by ischemic manifestations in brain or retina are the main symptoms of extracranial internal carotid artery (ICA) dissection. Unusually, cranial nerves may be affected. Isolated oculomotor nerve palsy is found only rarely. CASE: We present a 50-year-old nondiabetic man who experienced acute onset of right occipital headache which spread to the right retro-orbital region. Five days later he noticed diplopia and right blurred vision sensation. Neurologic examination disclosed only impaired adduction and upward gaze of right eye, slight ipsilateral pupillary dilatation, without ptosis. Brain MRI was normal. Angiography showed right internal carotid artery dissection with forward occlusion to the base of the skull. Intravenous heparin followed by warfarin was prescribed. The headache and the oculomotor nerve deficit gradually resolved in the next three weeks. DISCUSSION: Isolated oculomotor nerve palsy is underrecognized as a clinical presentation of extracranial ICA dissection. If the angiographic evaluation is incomplete without careful study of extracranial arteries, misdiagnosis may lead to failure to initiate early treatment to prevent thromboembolic complications. For this reason we draw attention to the need for careful evaluation of cervical arteries in patients with oculomotor nerve palsy. Mechanical compression or stretching of the third nerve are possible mechanisms, but the direct impairment of the blood supply to the third nerve seems to be the most plausible explanation.

Microsurgical Clipping

Objectives: Internal carotid artery (ICA) aneurysm often leads to oculomotor nerve palsy (ONP) that impairs eye movement. Currently, microsurgical clipping and endovascular coiling are the two major options to treat ONP. The purpose of the current study is to compare the clinical outcomes of the two methods in patients with ONP caused by ICA aneurysm.Patients and Methods: In the present study, we assessed the prognostic factors and recovery outcomes of a total of 90 ICA aneurysm-induced ONP patients, where 50 of them were treated with microsurgical clipping and 40 of them were treated with endovascular coiling. Within the endovascular coiling group, 20 of the patients were treated with balloon-assisted coiling and the other 20 were treated with stent-assisted coiling.Results: Overall, we achieved a 59% (53 out of 90) full recovery rate. Both surgical clipping and endovascular coiling treatment methods achieved similar recovery outcomes in the tested patients. However, within the endovascular coiling group, balloon-assisted coiling treatment demonstrated a significantly higher full recovery rate (17 out of 20) compared to stent-assisted coiling treatment (eight out of 20).Conclusion: In general, no significant difference was identified between the surgical and coiling treatments, and both procedures were considered as beneficial for ICA aneurysm-induced ONP.
