Spontaneous Dissection

✓ Spontaneous dissection of the internal carotid arteries, including those dissections resulting in total occlusion, may be a spontaneously reversible process. A patient who had angiographic evidence of bilateral complete internal carotid artery occlusions of different ages of onset illustrates this process. This case suggests certain considerations regarding the pathogenesis of these dissections.

✓ The authors report the case of a patient with transient ischemic attacks who was evaluated by duplex scanning, which demonstrated total carotid artery occlusion. Arteriography revealed what appeared to be a classic “string sign” in the cervical carotid artery, and a standard endarterectomy was planned. At surgery the internal carotid artery was found to be congenitally atretic, accounting for the string appearance of the arteriogram. The etiology, associated anomalies, differential diagnosis, and diagnostic evaluation of such lesions are discussed.

✓ A 44-year-old man experienced the sudden onset of horizontal diplopia and hemifacial numbness. Arteriography demonstrated a left intrapetrous carotid artery aneurysm. The patient was successfully treated with a left superficial temporal artery to middle cerebral artery bypass followed by balloon entrapment of the aneurysm. There have been at least 40 previously reported cases of aneurysms of the petrous portion of the carotid artery. These aneurysms can be mycotic, traumatic, or developmental in origin. They can present with massive otorrhagia or epistaxis from acute rupture or with decreased hearing and paresis of the fifth through eighth cranial nerves and, less frequently, of the ninth, 10th, and 12th cranial nerves caused by direct pressure. They can also produce pulsatile tinnitus, and sometimes they are discovered as a retrotympanic vascular mass during otological examination. The treatment of choice is carotid artery occlusion. Trapping of the aneurysm by detachable balloons eliminates immediately the risk of hemorrhage, offers the possibility of test occlusion of the internal carotid artery with the patient awake prior to permanent occlusion, and should also reduce the risk of thromboembolism. It should be preceded by a bypass procedure when preliminary evaluation indicates that the patient will not tolerate internal carotid artery occlusion.

Management Algorithm

Objectives Spontaneous recanalization of a chronic total occlusion of the extra-cranial internal carotid artery is an under-reported clinical entity. This paper reviews the different etiologies of internal carotid artery occlusion, its natural course, as well as the significance and our recommendations for the management of spontaneous internal carotid artery recanalization. Methods A review of literature on etiology, diagnosis, and treatment of internal carotid artery occlusion and recanalization was conducted. PubMed database was searched using the terms “internal carotid occlusion” and “recanalization”. Articles were reviewed and studies involving the management of internal carotid artery occlusion and spontaneous recanalization were included. We subsequently developed a management algorithm for chronic total occlusion of the internal carotid artery and spontaneous recanalization of such lesions based on the available evidence. Results Common etiologies of chronic total occlusion of the internal carotid artery include carotid atherosclerotic disease, cardioembolic, and carotid dissection. Progression of an asymptomatic to symptomatic occlusion is estimated at 2–8% annually. Well-compensated patients can be asymptomatic. In others, clinical symptoms range from ipsilateral or global hypoperfusion to embolic stroke in some cases of spontaneous recanalization. Spontaneous recanalization occurs in 2.3–10.3% of patients but rarely results in a cerebrovascular event. Conclusions Progression of an asymptomatic chronic total occlusion of the internal carotid artery to symptomatic is infrequent. The management algorithm of chronic total occlusion of the internal carotid artery and spontaneous recanalization of the internal carotid artery must be tailored to the patient based on symptoms, etiology of the lesion, imaging findings, surgical risk, and reliability for follow-up.

✓ The authors report a case of pituitary apoplexy occurring several hours after carotid angiography. The event was associated with stupor, focal headache, and left hemiparesis. Repeat angiography demonstrated intracranial occlusion of the right internal carotid artery. At surgery, a hemorrhagic pituitary adenoma was found to be compressing the internal carotid artery, and the removal of the tumor resulted in restoration of flow. The mechanism, presenting symptoms and signs, and treatment of pituitary apoplexy causing compression of a major vessel are discussed.

The Impact

The impact of ADAPT—“a direct aspiration first pass technique”—on intracranial vasculature is not well understood, since the change of arterial diameter is often not visible during aspiration. We present a unique case in which the impact of aspiration on the parent vessel was visualized due to a previously deployed Neuroform Atlas stent and a Pipeline embolization device. The patient presented with right internal carotid artery occlusion. An aspiration catheter was advanced over the microcatheter system and corked into the clot, located within the stents in proximal M1. The stents were seen to collapse both during electronic pump and hand aspiration with no evidence of stent migration. This demonstrates that it is crucial to engage the clot interface with the tip of the aspiration catheter while performing ADAPT. Placing the aspiration catheter remote from the clot may result in collapse of the artery proximal to the clot with subsequent ADAPT failure.(video 1)video 1.

Spontaneous Dissection

Internal carotid artery (ICA) dissection is an important cause of stroke in the younger population. Carotid stenting with or without angioplasty is usually the preferred treatment for symptomatic patients who have failed medical therapy. We report a case of a symptomatic internal carotid artery dissection at the petrous segment of the ICA initially treated conservatively with anticoagulation and antiplatlet agents. Due to early clinical deterioration from near complete carotid occlusion without adequate cross over flow, the patient underwent emergency stenting of the ICA. Post procedure angiography demonstrated no residual stenosis of the ICA. The patient progressively improved and at six months follow-up, the patient had no further symptoms, a normal neurological examination and improvement in the imaging findings. The successful clinical result in our case of ICA stenting for dissection as a ‘hemispheric rescue’ contributes to the growing literature of endovascular management of carotid dissection. The excellent mid term follow-up confirms the efficacy of this treatment for a dominant ICA.

✓ A patient with known internal carotid artery occlusion developed transient ischemic attacks in the distribution of the occluded vessel. Arteriography demonstrated a thrombus clearly originating from the internal carotid artery stump, which was unassociated with significantly stenotic atherosclerotic disease of the ipsilateral common or external carotid arteries. Stump angioplasty and endarterectomy led to complete and sustained cessation of further symptoms.

Current Guidelines

The efficacy of intravenous thrombolysis and endovascular therapy and their favorable treatment outcomes have been established in clinical trials irrespective of age. Current guidelines do not recommend an age limit in selecting eligible patients for reperfusion treatment as long as other criteria are satisfied. A 103-year-old woman was admitted at our hospital within 1 h of stroke onset secondary to a left internal carotid artery terminus occlusion. On admission, her National Institutes of Health Stroke Scale (NIHSS) score was 30, with a small left thalamic diffusion restriction lesion on MRI. Her medical history included paroxysmal atrial fibrillation, prior myocardial infarction, hypertension, chronic kidney disease, and diabetes mellitus. Her pre-stroke modified Rankin Scale score was 0, and she was fully independent before stroke. Once intravenous thrombolysis was started, the patient successfully underwent mechanical thrombectomy, and thrombolysis in cerebral infarction-3 recanalization was achieved 225 min after symptom onset. She showed dramatic recovery (NIHSS score of 5 after 48 h) and was discharged on day 7 with a modified Rankin Score of 1. To our knowledge, our patient is the second oldest documented patient who successfully underwent bridging therapy for stroke.
