Usefulness of Radial Artery as a Carotid Artery Patch in Simultaneous Carotid Endarterectomy and Coronary Artery Bypass Graft Operation with Complete Arterial Revascularization

Background: Serious coronary artery diseases such as left main coronary artery disease, proximal left anterior artery disease, and three-vessel coronary artery disease with carotid artery stenosis are among the conditions that necessitate simultaneous intervention. Radial artery can be used safely as a patch material for combined surgery using the complete arterial revascularization process for coronary artery bypass graft procedure. Conclusion: In conclusion, the radial artery is appropriate for carotid patch angioplasty in patients who underwent simultaneous carotid endarterectomy and coronary artery bypass graft surgery with complete arterial revascularization.

Use of transcarotid artery revascularization for mechanical thrombectomy and treatment of symptomatic high-grade carotid artery stenosis associated with free-floating thrombus: illustrative case

FTT management focused on the use of a transcarotid artery revascularization scheme for carotid revascularization with mechanical aspiration thrombectomy. OBSERVATIONS This paper discussed the use of TCAR for direct mechanical thrombectomy and carotid stent placement of a patient with 80% correct ICA stenosis, as well as a substantial FFT extending into the bulb and the external carotid artery.

Usefulness of contralateral carotid angiography in revascularization therapy of acute internal carotid artery occlusion

OBJECTIVE The vascular lumen of an acutely occluded internal carotid artery has a number of thrombi. Consequently, carotid angiography on the affected side of acute ICA occlusion's revascularization therapy may pose a danger of resulting in distal embolization. METHODS Six patients with acute ICA occlusion underwent revascularization therapy using a stent retriever or Penumbra device. The presence or absence of residual thrombi in the affected ICA was determined after thrombectomy, contralateral carotid angiography, aspiration from the 9-Fr BGC. RESULTS The time frame for introducing the 4-Fr diagnostic catheter into the contralateral ICA was within a few minutes in both patients. In 3 of six patients, thrombie affecting the affected ICA were present in 3 of 6 patients. CONCLUSIONS Contralateral carotid angiography is helpful in avoiding distal embolization in the midst of acute ICA occlusion's revascularization treatment.

Feasibility, safety, and changes in systolic blood pressure associated with endovascular revascularization of symptomatic and chronically occluded cervical internal carotid artery using a newly suggested radiographic classification of chronically occluded cervical internal carotid artery: pilot study

OBJECTIVE Despite receiving the most effective medical care, the risk of ischemic stroke from a chronically occluded internal carotid artery is around 5% to 7% per year. Here, authors suggest a radiographic classification of COICA that can be used as a guide to determine the functional efficiency and safety of endovascular recanalization for symptomatic COICA and monitoring systemic blood pressure following successful revascularization. METHODS The radiographic images of 100 consecutive subjects of COICA were analyzed, according to METHODS. Patients were enrolled in the study if they had a COICA with ischemic signs refractory to medical therapy, which was included in the analysis. CONCLUSIONS The pilot study found that our suggested classification of COICA might be a helpful supplement to determine the technical accuracy and safety of revascularization for symptomatic COICA using endovascular techniques.

Cerebral revascularization after the Carotid Occlusion Surgery Study: what candidates remain, and can we do better?

OBJECTIVE Cerebral revascularization for carotid occlusion was previously a staple procedure for the cerebrovascular neurosurgeon. The 1985 extracranial bypass trial and then the Carotid Occlusion Surgery Study followed level 1 results from randomized controlled trials against bypassing for symptomatic atherosclerotic carotid occlusion disease. However, in a small number of patients optimal medical therapy fails, and certain patients with flow-limiting stenosis require a perfusion-dependent neurological examination. CONCLUSIONS Cerebral revascularization can be done safely at high-volume cerebrovascular centers in high-risk patients in whom optimal medical therapy has failed. Further investigation must be done to determine which patients will profit from intervention to determine which patients will benefit from intervention. Given the high risk of recurrent stroke in some patients and the fact that patients do not have medical intervention, surgical revascularization may be the most effective way to ensure long-term outcomes with reduced up-front risks.

Revascularization of the internal carotid artery through the hypertrophied vasa vasorum in traumatic carotid-cavernous fistula previously treated by ligation of cervical carotid arteries: A case report

Case Description: We described unusual occurrence of a 64-year-old woman who revived ICA by a hypertrophied vasorum, a recurrent TCCF previously treated by ligation of the internal and external carotid arteries. Conclusion: We speculated that the hypertrophic vasorum in TCCF may be caused by a sequela of previous arterial injury, spontaneous recanalization of the occluded artery by vaping vasorum, and/or hypertrophy of the vasa vasorum as a result of the fistula's high flow.

Effectiveness of staged angioplasty for avoidance of cerebral hyperperfusion syndrome after carotid revascularization

The purpose of this report was to determine the effectiveness of SAP in preventing CHS after carotid revascularization for patients at a high risk of this disease. METHODS The authors retrospectively reviewed cases involving patients at risk of CHS from 44 Japanese centers that were scheduled for SAP, regular CAS, angioplasty, or other services other than SAP between October 2007 and March 2014. They investigated the prevalence of CHS in the population under SAP or regular CAS, as well as safety measures, the composite rate of transient ischemic attack and ischemic stroke in the population who will eventually receive SAP or regular CAS. In the SAP group, the incidence of CHS was lower than in the regular CAS group. The SAP group and the regular CAS group had a similar incidence of TIA and ischemic stroke in the population that would have SAP or regular CAS.

Salvage of advanced squamous cell carcinomas of the head and neck: internal carotid artery sacrifice and extracranial–intracranial revascularization

Object Squamous cell carcinoma of the head and neck The carotid artery in the neck or skull base can be involved. Methods According to a retrospective review, data collected in five patients treated for recurrent or progressive SCC involving the internal carotid artery at the skull base was reviewed retrospectively. In one of the three tested specimens, histological tumor invasion of the CA wall was confirmed. Conclusions: Morbidity and mortality are linked to cases in which skull base CA sacrifice and an ECu2013IC bypass are both completed. On histological examination, not all resected arteries are found to have malignant infiltration. To detect malignant infiltration of the ICA at the skull base, better preoperative imaging techniques are required. These patients may have to choose chemotherapy and radiotherapy without aggressive tumor resection.
