Carotid stenoses ≥50% are associated with increased risk for stroke that can be reduced by prophylactic carotid endarterectomy (CEA). Calcifications in arteries can be detected in panoramic radiographs (PRs). In a cross-sectional study, we analyzed (1) extirpated plaques for calcification, (2) how often PRs disclosed calcified plaques, (3) how often patients with stenoses ≥50% presented calcifications in PRs, and (4) the additional value of frontal radiographs (FRs).
Patients (n = 100) with carotid stenosis ≥50% were examined with PRs and FRs before CEA. Extirpated carotid plaques were radiographically examined (n = 101).
It was found that 100 of 101 (99%) extirpated plaques were calcified, of which 75 of 100 (75%) were detected in PRs; 84 of 100 (84%) patients presented carotid calcifications in the PRs, in 9.5% contralateral to the stenosis ≥50%.
Carotid calcifications are seen in PRs in 84% of patients with carotid stenosis ≥50%, independent of gender. FRs do not contribute significantly to this identification.
颈动脉狭窄≥50%与中风风险增加相关，预防性颈动脉内膜切除术（CEA）可降低该风险。动脉钙化可在全景X线片（PR）中检测到。在一项横断面研究中，我们分析了：（1）切除斑块中的钙化情况；（2）PR显示钙化斑块的频率；（3）狭窄≥50%的患者PR中出现钙化的频率；（4）额部X线片（FR）的附加价值。
对100例颈动脉狭窄≥50%的患者在CEA术前进行PR和FR检查。对切除的颈动脉斑块进行X线检查（n = 101）。
发现101个切除斑块中有100个（99%）有钙化，其中100个中的75个（75%）在PR中被检测到；100例患者中有84例（84%）PR显示颈动脉钙化，其中9.5%在狭窄≥50%的对侧。
84%的颈动脉狭窄≥50%的患者PR中可见颈动脉钙化，与性别无关。FR对这种识别没有显著贡献。
