Prevention and treatment of complications of carotid angioplasty and stenting in the elderly / 中华老年医学杂志

ABSTRACT

ObjectiveTo summarize the prevention and treatment of complications of carotid angioplasty and stenting (CAS) in the elderly. Methods88 cases (≥60 years) who underwent carotid angioplasty and stenting were collected from our hospital. The prevention and treatment of complications were analyzed retrospectively. ResultsNinety-two self-expanding stents were placed in the 88 cases and the technical success rate was 100%. The degree of stenosis was significantly improved from 82.6% to 13.2%. All patients were followed up for 3-12 months. Carotid sinus reaction was observed in 23 cases (26.1%) and it was more often in ≥70 years group than in 60～69 years group (P＜0.05). Meanwhile, compared with the distance ＞10 mm, Carotid sinus reaition was more often in the distance ≤ 10 mm between carotid bifurcation and maximum stenotic lesion (P＜ 0.05). Hypertension occurred in 6 cases, cerebral hyperperfusion syndrome in 4 cases including 1 case of cerebral hemorrhage. There were cases with cerebral ischemia in 1 case, cerebralvaseular spasm in 4 cases, acute renal insufficiency in 3 cases and ecchymosis and hematoma at the puncture site in 7 cases. There were 3 cases of transient ischemic attack, 1 case of myocardial infarction, 1 case of cerebral hemorrhage, 2 cases of mild neurological deficits and no death occurred during the period of follow-up. ConclusionsThere is higher risk for elderly patients undergoing CAS, but careful preoperative preparation and properly treatment may avoid the occurrence of complications.
