Nitinol Stents

This is a carotid artery stent (CAS) case report, which avoids post-stent deployment angioplasty (Post-SDA), with duplex confirmed continued stent expansion at 1, 3 and 30-day post deployment. This report confirms that self-expanding nitinol stents in the carotid artery may not require Post-SDA. We believe CAS can be performed without Post-SDA, which helps reduce the occurrence of intraoperative hemodynamic depression.

Background To prevent ischemic complications during carotid artery stenting, accurate detection of plaque protrusion and appropriate additional treatment are essential. Here, we introduce a novel method for the detection of plaque protrusion under distal balloon protection using three-dimensional rotation angiography—“retrograde 3DRA.” We evaluated the safety and efficacy of this method. Materials and methods We retrospectively analyzed 28 consecutive carotid artery stenting procedures under distal balloon protection at our hospital between July 2017 and August 2019. The first line of protection was dual balloon protection (proximal and distal balloon). After stent deployment, balloon dilatation, and subsequent blood aspiration, 3DRA was performed with the injection of diluted contrast medium from the aspiration catheter positioned just proximal to the distal protection balloon. The stent lumen was analyzed by obtaining the reconstruction maximum intensity projection image. Results Among the 28 cases, all cases could be assessed for in-stent plaque protrusion using “retrograde 3DRA.” We were able to evaluate the stent lumen clearly. There were three cases (10.7%) in which plaque protrusion could be confirmed. Since additional balloon dilatation was performed for all protrusion cases under continuing balloon protection, no ischemic complications occurred. Conclusion Retrograde 3DRA could be safe and useful for the detection of plaque protrusions and to avoid ischemic complication for tolerable cases of internal carotid artery transient balloon protection.

Abstract OBJECTIVE: Endovascular coil embolization of saccular intracranial aneurysms is safe and effective, but long-term results are dissatisfying. Reconstructive treatments using stents improve occlusion rate and protect parent vessels. We present data on our experience with a new self-expanding stent manufactured with braided nitinol wires. METHODS: Twenty-five saccular, complex, and broad-necked intracranial aneurysms in 21 patients were treated electively. They were located at the internal carotid artery (10), basilar trunk (5), cavernous carotid artery (4), basilar tip (2), anterior cerebral artery (2), anterior communicating artery (1), and middle cerebral artery (1). Eleven aneurysms exhibited recanalization after primary endovascular treatment without stent. RESULTS: Stent deployment was successful in 24 lesions, and additional coil embolization was performed in 23. No permanent neurological deficits were encountered consequent to endovascular procedure. Complete or partial occlusion immediately after stent deployment was achieved in 19 aneurysms, whereas no immediate coil embolization was chosen in 6 cases. There were two thromboembolic events related to the deployment of the Leo stent, one failure of stent deployment, difficulties in stent positioning in three cases, and one asymptomatic parent artery occlusion after 7 months. Follow-up (available in 18 patients and 21 aneurysms and obtained at 3–12 mo; average, 5 mo) revealed patent stents in the remaining cases. Angiographic recurrences arose in three lesions, which were retreated without complications. CONCLUSION: Primary and recurrence treatment of saccular and broad-necked intracranial aneurysms using the Leo stent is feasible and effective. No permanent neurological deficits were associated with stent placement. Short-term follow-up identified intact parent arteries and stable occlusion rates in the majority of cases.
