AI Article Synopsis
- The study focuses on a new technique called balloon-assisted catheterization of occluded carotid artery (BOCA) that helps in treating acute ischemic strokes caused by tandem occlusions in the internal carotid artery (ICA).
- The method was retrospectively reviewed in 10 patients, showing high success rates with all patients achieving ICA recanalization and significant improvement in blood flow.
- Results indicated that BOCA reduced surgery time and effectively managed severe occlusions, making it a promising approach for acute stroke interventions.
Article Abstract
Background: Acute ischemic stroke from tandem occlusion of internal carotid artery (ICA) poses a technical challenge to neurointerventionalists.
Objective: To present a novel balloon-assisted catheterization of occluded carotid artery (BOCA) technique used for rapid and effective catheterization of occluded/critically stenosed ICA in tandem occlusion.
Methods: A retrospective review of 10 patients with tandem carotid occlusion, treated with BOCA technique for revascularization between July 2020 and June 2021, was performed. Clinical, radiographic, and procedural data; details of BOCA technique; complications; and outcomes were reviewed.
Results: Of the 10 patients, 8 (80%) had complete occlusion of the cervical ICA and the remaining 2 had high-grade stenosis with poor intracranial flow. The mean age was 63.2 years. The mean presenting NIH Stroke Scale was 13.4. The BOCA technique resulted in recanalization of ICA in all patients and allowed mechanical thrombectomy of middle cerebral artery. Thrombolysis in cerebral infarction grade 2b/3 was achieved in all 10 patients. The mean groin-to-reperfusion time was 41.4 minutes. The mean internal carotid artery stenosis was 99.7% preoperatively and 41.1% postoperatively. Only one patient needed stent at the end of the procedure because of dissection.
Conclusion: The BOCA technique can be used in distal first approach for acute stroke from tandem ICA occlusion. This technique allows direct guide catheterization of occluded ICA by tracking over a partially inflated balloon.

In this article, the authors aim to offer a perspective on self-compassion capable of becoming part of a unified psychology; however not "from scratch", but based on what Neff (2003a, b) proposed. This is through the analysis and refinement of her theory in two stages. First, they check whether the supposed six factors exist in the constitution of self-compassion using the exploratory factor analysis (EFA) technique in a collected sample for this study (249 participants, 69.

Bertolotti's Syndrome, a subset of lumbosacral transitional vertebrae (LSTV), is one cause of chronic low back pain (LBP), and a commonly overlooked differential diagnosis. The incidence of Bertolotti's Syndrome has been underestimated in the past and is common in those of younger ages around 30-40. Although diagnostics, imaging methods, and treatment algorithms have been improved in the past few years, there is no gold standard and more long-term, prospective research is needed.

Objective: Enhanced Recovery After Surgery (ERAS) clinical pathways have demonstrated improved perioperative outcomes after major surgery. However, its adoption within vascular surgery has been limited. In this study, we examined the impact of an ERAS protocol with multimodal anesthesia on open abdominal aortic aneurysm (AAA) repair by comparing early outcomes before and after its implementation.
