Background In cases of acute ischemic stroke, manual aspiration of the thrombus is commonly performed with a balloon guiding catheter placed in the cervical segment of the internal carotid artery (ICA). However, most manual aspirations using a balloon guiding catheter are combined with inner catheters, as in the direct aspiration first pass technique (ADAPT). We experienced some cases of acute ischemic stroke with proximal ICA occlusion due to cardiogenic thrombus where we obtained sufficient recanalization by simple manual aspiration from inflated Optimo 9F balloon catheters (Tokai Medical Products, Japan) placed in the origin of the cervical segment of the ICA without any inner catheter or stent retriever. We perform by preference this procedure, named the simple Aspiration with Balloon Catheter (simple ABC) technique. Herein, we report two recent cases and discuss this procedure. Case presentation Case 1: An 80-year-old man with paroxysmal atrial fibrillation developed left ICA occlusion. We performed the simple ABC technique and obtained a large amount of dark red and white thrombus. Puncture-to-reperfusion time was 14 minutes with Thrombolysis in Cerebral Infarction (TICI) grade 3. Case 2: A 69-year-old man with chronic atrial fibrillation developed left internal carotid occlusion. We performed the simple ABC technique and obtained a large amount of dark red thrombus. Puncture-to-reperfusion time was 15 minutes with TICI grade 2b. Conclusion The simple ABC technique is useful to deal with a large amount of thrombus, shortens procedure time, enables less invasive thrombectomy, and can shift immediately to subsequent procedures such as delivering a stent retriever or ADAPT.
