Carotid Artery Stenting in Patients at Surgical High Risk: Clinical and Ultrasound Findings
Angioplasty and stenting (A/S) provide an alternative for patients with simultaneous severe cardiac and cerebrovascular disease, or with medical illnesses which carry a high perioperative risk.

Zusammenfassung: | Angioplasty and stenting (A/S) provide an alternative for patients with simultaneous severe cardiac and cerebrovascular disease, or with medical illnesses which carry a high perioperative risk. We conducted A/S in 20 high-risk patients (15 males, 5 females, mean age = 64.5 years, range = 49–83 years) with symptomatic (n = 16) and asymptomatic (n = 4) high-grade stenosis (>70%, NASCET criterion) of the internal carotid artery. Patients had neurological examinations before, during and after the procedure. Color-coded duplex sonography was performed before and 24 h and every 3 months after the procedure; the 3-month examination also included cerebral angiography. The mean degree of stenosis was reduced from 85.75 ± 7.47 to 8.0 ± 22.09% in angiography. In an 18-month follow-up with color-coded duplex sonography the effects of the A/S could be visualized effectively: 2 with local, transient vasospasms, 1 with asymptomatic occlusion, 2 carotid arteries with remaining stenosis of 50% and 2 with minimal hyperplasia within the stent. In conclusion, in patients with a high perioperative risk, A/S is a therapeutic alternative to surgery. |
