Insights
This study evaluated a scoring protocol for carotid stenosis treatment, finding it effective in guiding decisions between endarterectomy and stenting. The protocol demonstrated high adherence and positive patient outcomes with minimal complications.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Neurosurgery
Background:
- Carotid stenosis management requires careful selection between endarterectomy and stenting.
- A previously described protocol aids in decision-making for these interventions.
Purpose of the Study:
- To report experiences using a scoring protocol for selecting between carotid endarterectomy and stenting.
- To assess the protocol's effectiveness in a real-world clinical setting.
Main Methods:
- A scoring protocol was applied to 105 consecutive patients with carotid stenosis (October 2014 - March 2018).
- Patients included symptomatic stenosis ≥50% (n=80) and asymptomatic stenosis ≥80% (n=25).
- Treatment decisions (stenting or endarterectomy) were compared against protocol recommendations.
Main Results:
- The protocol was followed in 93.3% of cases; 58.1% of treatments were protocol-dictated.
- Stenting was performed in 73 patients, endarterectomy in 32.
- No major strokes or restenoses occurred during 12-month follow-up; 2.8% experienced minor strokes.
Conclusions:
- The scoring protocol effectively guides the selection of endarterectomy versus stenting for carotid stenosis.
- Simultaneous consideration of both procedures, guided by the protocol, is recommended.
- The protocol is applicable in clinical practice with high adherence and favorable patient outcomes.
Abstract:
Previously we described the protocol-based decision for choosing the proper surgical treatment option for carotid stenosis. The objective of this study is to describe our experiences of using this scoring protocol in the selection of endarterectomy or stenting for carotid stenosis. Between October 2014 and March 2018, the scoring protocol was applied to a total of 105 consecutive patients. Eighty (76.2%) patients had symptomatic stenosis ≥ 50%, and 25 (23.8%) patients had asymptomatic stenosis ≥ 80%. We also speculated about how effectively the protocol worked in the real clinical setting. Stenting was performed in 73 patients and endarterectomy in 32 patients. Overall, 98 (93.3%) patients were treated according to the protocol, while the protocol was violated in seven (6.7%) patients. Sixty-one (58.1%) patients received treatments that were decided by the protocol. There were 37 (35.2%) patients who had the same score for both treatment options. Among these patients, 28 patients underwent stenting and nine patients underwent endarterectomy. In the stenting cases, 90.4% of the patients followed the protocol and violations occurred in 9.6%. In the endarterectomy cases, all of the patients followed the protocol. Overall, one patient had a procedure-related complication without morbidity. During the 12-month follow-ups, there were no restenoses or major strokes. Minor strokes were diagnosed in three (2.8%) patients. In patients with carotid artery stenosis, stenting and endarterectomy should be considered simultaneously together, not against each other. Our scoring protocol can be used to weigh these options and applied in clinical practice.
