“…In the previous literature and this study, cerebral infarctions related to procedure did not occurred, but how to prevent the complication is crucial. During the procedure, proximal embolic protection (MOMA or Parodi system) may prior to distal embolic protection for protecting the brain from distal embolization [27].…”

To investigate the feasibility and efficacy of angioplasty and stenting for symptomatic occlusion of carotid artery. From December 2004 to June 2009, 17 patients with progressive or reoccurred ischemic stroke or repeated transient ischemic attack resulted from the total occluded carotid artery underwent angioplasty and stenting were reviewed. All patients with successful procedure were followed up. Clinic and angiography data were documented prospectively. The median time from symptoms onset to procedure was 23 days (range 3-94 days). Twelve of the 17 patients (70%) were obtained technique success. Eight patients were observed the collapse of internal carotid artery between occluded location to origin of ophthalmic artery after the occlusion was patent. Two patients had clots which were solved with urokinase. The collapsed internal carotid artery was improved markedly in the compute tomography angiograph 7 days after the procedure. No any complications related procedures occurred. One patient died from myocardial infarct and one suffered from ischemic minor stroke in brainstem for a median follow-up of 346.5 days. One of 9 patients (11.1%) was observed in-stent stenosis in the follow-up angiography. Angioplasty and stenting was a potential alternative therapy for symptomatic occlusion of carotid artery. Further study is required to determine the safety of this treatment.

“…Second, vascular complications in endovascular recanalization for occluded ICA are common, including stroke, carotid pseudoaneurysm formation, iatrogenic carotid-cavernous fistula, and cervical extravasation. 23,24 Third, balloon dilatation and stent deployment in ICA occlusion could result in ECA stenosis exacerbation and occlusion. 23,25 Our study findings indicated that no severe complications occurred within the perioperative period of ECA stenting, despite 77.8% of our study patients having been diagnosed with severe coronary artery disease.…”

Objectives: This study aimed to evaluate the safety and clinical efficacy of external carotid artery (ECA) stenting in patients with ipsilateral internal carotid artery (ICA) occlusion.Background: In patients with ICA occlusion, severe ipsilateral ECA stenosis may exacerbate pre-existing cerebral ischemia and cognitive impairment. It remains unclear whether ECA stenting to normalize ECA collaterals to the cerebralis alleviates cerebral ischemia and improves cognitive function. Methods: From January 2008 to June 2019, we retrospectively collected clinical data of 36 consecutive patients with ipsilateral ICA occlusion who had undergone ECA stenting (mean age, 66.7 ± 8.3 years; males, n = 26 [72.2%]). Neurocognitive test results, including Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MOCA) tests, symptom assessment, and adverse events were recorded.Results: ECA stenting was successful in all 36 patients. Intra-operatively, six (16.7%) patients experienced hemodynamic depression during balloon dilation and recovered completely within 2 days. Within a 12-month follow-up period, two patients experienced a transient ischemic attack, one patient had a contralateral minor stroke, and 33 patients remained asymptomatic. No other adverse events occurred in the perioperative or follow-up periods. Compared with baseline, significant MMSE (25.3 ± 1.3 vs. 23.6 ± 1.7; p < .05) and MOCA (24.1 ± 1.3 vs. 22.8 ± 1.7; p < .05) test score improvements were observed 3 months post-operatively and were maintained throughout follow-up.Conclusions: ECA stenting may improve cerebral ischemia and cognitive function in patients with severe ECA stenosis and ipsilateral ICA occlusion; however, further research is required to support our findings.
