Outcomes after Transverse-Incision 'Mini' Carotid Endarterectomy and Patch-Plasty.

Purpose: Traditional exposure for carotid endarterectomy (CEA) involves making a longitudinal incision parallel to the anterior border of the sternocleidomastoid. Such incisions can be painful, aesthetically displeasing, and associated with a high incidence of cranial nerve injury (CNI). This study describes the outcomes of CEA performed through small (<5 cm long), transversely oriented incisions located directly over the carotid bifurcation, as identified by color-enhanced Duplex ultrasound.

Materials And Methods: Patient demographics and operative data were collected retrospectively from an in-house database of consecutive vascular patients undergoing CEA with a small transversely oriented incision for both symptomatic and asymptomatic carotid artery stenoses.

Results: A total of 52 consecutive patients underwent CEA between 2012 and 2016 (median age, 73.5 years; interquartile range, 67-80.3; male/female ratio, 40:12). CEA was performed under regional/local anesthesia (LA) in 48 (92.3%) patients, with 4 (7.7%) being performed under general anesthesia. One patient under LA experienced neurological dysfunction intraoperatively (manifesting as an inability to count out loud) that resolved with insertion of shunt. One patient experienced a transient neurological event (expressive dysphasia) within the immediate postoperative period, which resolved within 6 hours. No in-hospital death or perioperative major adverse cardiovascular events were noted. No persistent CNIs nor bleeding complications necessitating re-exploration were reported. Follow-up data were available for a median period of 3.1 years and for all patients. Three patients experienced strokes following discharge (2 strokes contralateral to and 1 transient ischemic attack ipsilateral to the operated side).

Conclusion: Small, transversely orientated incisions, hidden within a neck skin crease can be safely performed in the majority of patients undergoing CEA.
