Summary

Carotid endarterectomy (CEA), an important surgical approach for managing carotid plaque, has evolved over more than 70 years but still cannot be applied to all tandem carotid lesions (TCLs) because of the wide range of these lesions. Herein, the investigators introduce an innovative CEA, Gao's triple eversion CEA (GTE-CEA), for the treatment of TCLs.

Detailed description

The investigators retrospectively reviewed the charts of patients who underwent GTE-CEA performed by the same group of vascular surgeons since 17 September, 2021. Patients who did not meet the diagnostic criteria for carotid artery stenosis (CAS); those with asymptomatic CAS \< 50%, preoperatively confirmed by digital subtraction angiography (DSA) or computed tomography angiography (CTA); and those with stenosis at the opening of the common carotid artery (CCA) were excluded from our study.

Conditions

• Carotid Artery Stenosis

Interventions

Type	Name	Description
PROCEDURE	Gao's triple eversion carotid endarterectomy	The carotid sheath is dissected in front of the sternocleidomastoid muscle to expose sufficient lengths of the CCA, ECA, and ICA. After raising the systolic blood pressure to 180 mmHg and intravenously injecting 1 mg/kg heparin, the superior thyroid artery is lapped and severed, and the CCA is occluded proximally to the CCA plaque, based on the plaque location shown by preoperative CTA and by intraoperative arterial exploration. Subsequently, the ECA and ICA are blocked individually. The ICA is cut diagonally at the CCA fork and the ECA is transected approximately 5 mm above its beginning. The plaque is removed with tweezers after eversion of the ICA. This process is repeated for the ECA. Finally, the long segment of plaque in the CCA is stripped proximally, followed by thorough removal of the debris on the peeling surface using heparin irrigation.
