Summary: | Carotid stenosis is a complication of cervical radiotherapy. In these cases carotid angioplasty has been considered as the elective revascularisation treatment. Yet, the indication to treat is under discussion due to the high rate of restenosis and the scarcity of studies conducted on the long-term development.
To report on a series of patients with carotid stenosis following radiotherapy who were treated by means of angioplasty, the aim being to analyse their long- and short-term development.
Of a series of 426 patients with carotid stenosis treated by endovascular means, 12 of them (2.8%) had previously received radiotherapy in the neck. All of them were submitted to a clinical and imaging follow-up. Data were collected concerning the rate of complications during the first four weeks and in the long term, as well as the rate of restenosis in the follow-up.
The mean interval between radiotherapy and the detection of stenosis was 14.7 years. Ten patients (83.3%) were symptomatic. No complications occurred during the first four weeks following the angioplasty. The mean follow-up time was 45.09 months: 16.7% of patients presented a stroke, 8.3% suffered acute myocardial infarction and 33.3% died (16.6% due to cancer). At least six patients (50%) were diagnosed with restenosis, all equal to or greater than 50% and none of them were symptomatic.
Carotid angioplasty is a safe, effective technique in stenosis following radiotherapy, with few short-term complications. The rate of carotid restenosis is high. The main cause of death is cancer. |
