Clinical Value

Objective: To explore the clinical value of carotid artery stent implantation (CAS) and carotid endarterectomy (CEA) in the treatment of patients with severe internal carotid artery stenosis. Methods: 88 patients with severe carotid artery stenosis who underwent CAS and CEA in the First People’s Hospital of Changde City (hereafter referred as “our hospital”) from January 2018 to December 2020 were selected as the research objects and divided into CAS group (n = 43) and CEA group (n = 45). To understand the clinical application value and feasibility of the two surgical schemes by comparing the general situation, cerebral blood flow, MMSE scale, MOCA scale score and serum miR-145, IGF1R levels of the two surgical schemes. Conclusions: CAS and CEA in the treatment of patients with severe internal carotid artery stenosis, have good curative effect, can effectively improve the patient's cerebral blood flow, regulate serum miR-145, IGF1R levels, promote the recovery of cognitive function, but relatively speaking, the incidence of stroke and hypotension after CAS is higher, and the incidence of hypertension after CEA is higher.

Diameter reductions in the internal carotid artery (ICA) and vertebral artery (VA) contribute to the decline in brain blood with hypotension. The decline in vertebral blood flow with hypotension was greater when carbon dioxide was low; this was not apparent in the ICA.

Probe Holder

SUMMARY:Regional cerebral blood flow (rCBF) during internal carotid artery (ICA) occlusion for endarterectomy can be measured without inconvenience using the probe holder illustrated.When mean ipsilateral hemispheric CBF exceeds 20 ml/100 gm/min, an intraluminal bypass is not necessary (63% of patients), except in patients with extensive cerebrovascular disease in whom rCBF should also exceed 20 ml/100 gm/min in all areas. ICA “stump” pressure is falsely high in about 20% of patients, and is therefore not a dependable criterion for selecting patients who need shunting.While intraoperative shunting is capable of restoring pre-occlusion CBF levels, it does not eliminate the risk of intraoperative ischemic neurological deficit of probable embolic origin.
