Introduction. Carotid angioplasty and internal carotid artery stenting is the
therapeutic method of choice in the treatment of carotid restenosis, but when
it is not technically feasible (expressed tortuosity of supraaortic branches,
calcifications, presence of pathological elongation of very long lesions) a
redo surgery is indicated. Objective. The aim of our study was to examine the
benefits and risks of redo surgery in patients with symptomatic and
asymptomatic significant internal carotid artery restenosis and its impact on
early and late morbidity and mortality. Methods. The study included 45
patients who were surgically treated for a hemodynamically significant
internal carotid artery restenosis from January 2000 to December 2009.
Surgical techniques included redo endarterectomy with direct suture, redo
anderectomy with a patch plastic and resection with Dacron tubular graft
interposition. The patients were followed for postoperative neurological
ischemic events (transient ischemic attack (TIA), stroke), local surgical
complications and lethal outcome after one month, six months, one year and
after two years). Results. In the early postoperative period (up to 30 days)
there were no lethal outcomes. TIA was diagnosed in four patients (8.8%),
minor stroke in one patient (2.2%) and one patient (2.2%) also had cranial
nerve injury. After two years two patients died (4.4%) due to fatal
myocardial infarction, three patients (6.5%) had ipsilateral stroke and one
patient developed graft occlusion (2%). Conclusion. In the case of
symptomatic and asymptomatic carotid restenosis that cannot be treated by
carotid percutaneous angioplasty, redo surgical treatment is therapeutic
option with an acceptable rate of early and late postoperative complications.
