RESUMO
Objectives: To report our experience and clinical results of neurosalvage techniques, performed by interventional cardiologists without moving the patient, to manage cerebral thromboembolic complications. Background: Iatrogenic emboli may be released during an endovascular procedure, causing permanent neurological complications and catastrophic outcomes. Methods: Between July 2013 and December 2017, a total of eight patients suffered from embolic complications during endovascular procedures (two radiofrequency catheter ablation, five coronary angiogram/angioplasty, and one subclavian artery angioplasty). Catheter-based neurosalvage was attempted by experienced interventional cardiologists promptly in the same catheterization room. Results: The embolized locations were the M1 segment of the middle cerebral artery in four patients, the M2/M3 segments in three, and the basilar artery in one. Access to the supra-aortic vessels was achieved. Local intra-arterial thrombolysis was given in five patients (63%) and balloon angioplasty in three (38%). Intra-arterial thrombectomy with a stent retriever was attempted in three patients but failed in one. A combination of different techniques was used in three patients (38%). Final thrombolysis in cerebral infarction grade 3 flow was achieved in seven patients (88%). Favorable clinical outcomes at 1-month follow-up (modified Rankin scale of 0-2) were observed in seven patients (88%), and none of the patients had died at 12 months. Conclusions: Our experience demonstrated that acute embolic complications during an endovascular procedure can be salvaged by interventional cardiologists with acceptable angiographic and clinical results.
