Background: Embolic protection devices are commonly used to prevent cerebral embolism during carotid artery stenting (CAS). However, the PercuSurge Guardwire device, a distal balloon protection device, was discontinued in April 2021. We present a case of successful CAS using a new distal balloon protection system. The procedure, referred to as the jailbreak technique, was performed via transradial access.
Methods: A 67-year-old man underwent CAS, using the jailbreak technique, for right carotid stenosis with a vulnerable plaque. 6-French (Fr) and 4-Fr Simmons guiding sheaths were delivered into the right common carotid artery via the right and left transradial access, respectively. Distal balloon protection was provided using a 2.6-Fr dual-lumen balloon microcatheter (Pinnacle Blue 20, Tokai Medical Products, Aichi, Japan) via the 4-Fr Simmons guiding sheath. A 4.2-Fr catheter was coaxially delivered proximal to the balloon and distal to the lesion.
Results: After CAS was successfully performed via the 6-Fr Simmons guiding sheath, the Pinnacle Blue 20 was retrieved through the 4.2-Fr catheter without interfering with the distal stent flare and stent struts. Postprocedural neuroimaging revealed no evidence of ischemic stroke.
Conclusions: The jailbreak technique allows distal balloon protection during transradial CAS. This is a useful treatment option for patients with carotid stenosis.

Ingestion of foreign bodies is a prevalent issue in clinical practice, with fish bones being the predominant cause. While the upper gastrointestinal tract is commonly affected, small intestine impactions pose significant diagnostic challenges due to nonspecific symptoms and lack of awareness of foreign body ingestion. Herein, we describe a case presenting with recurrent, unexplained abdominal pain and hematochezia.

Background: The elderly population (≥80 years) were underrepresented in recent trials of endovascular thrombectomy (EVT) for anterior circulation large vessel occlusion acute ischemic stroke (LVO-AIS) with low Alberta Stroke Program Early CT Score (ASPECTS) (≤5).
Methods: This study analyzed data from a prospectively maintained database of 37 thrombectomy centers. The primary cohort of the study comprised patients with LVO-AIS aged ≥80 who underwent EVT with ASPECTS≤5 from 2013 to 2023.

Background And Purpose: Proximal protection devices, such as TransCarotid Artery Revascularization (TCAR, SilkRoad Medical, Sunnyvale), aim to yield better outcomes in carotid artery stenting (CAS) than distal protection devices by preventing plaque embolization to the brain. However, transfemoral catheters may not fully reverse flow from the external carotid artery (ECA) to the internal carotid artery (ICA). We assess a new balloon-sheath device, Femoral Flow Reversal Access for Carotid Artery Stenting (FFRACAS), for this purpose.

We present a case of a 60-year-old man with claudication in his right foot; the patient had received stent-graft implantation for the right superficial femoral artery (SFA) 1 year ago. Computed tomography angiography suggested stent occlusion of the right SFA, and a thrombus was considered to cause occlusion. To avoid distal embolization, we performed lesion recanalization via a trans-ankle intervention.

We describe a 54-year-old man with type 2 diabetes mellitus, ischemic myopathy, pulmonary hypertension, and end-stage renal disease who was admitted for heart failure and listed for a dual cardiac-renal transplantation. Extensive calcification in the iliac arteries prevented clamping. Proximal endovascular balloon control of the left iliac artery was achieved using contralateral access; distal control was established by passing a Fogarty catheter distally through an iliac arteriotomy, later used for anastomosis of the cadaveric conduit.
