Eight carotid stented lesions were analyzed, of which 4 (50%) presented failures. Stent failures in iliac arteries were due to delayed healing, in femoral arteries due to intimal calcifications and stent integrity, and in carotid arteries due to underlying lipid-rich necrotic core causing ulceration; delayed healing (bare struts) was a common reason for stent failure in every type of peripheral bed.</p><p><strong>Conclusion: </strong>Our review showed that we have minimal data on the actual behavior of stents in humans, although it is fundamental to understand their performance.

Sensitivity, specificity, Dice similarity coefficient (DSC), and volumetric similarity were calculated to evaluate the performance of both methods.

A simple planning program was designed, and an automated laser fenestration machine was built to assist in planning and modification of endograft in cases with complex aortic aneurysm anatomy requiring repair. The planning program generates a patient's template based on computerized tomography angiography. The endograft is un-sheathed in a sterile environment and then scanned to generate an endograft template. The 2 templates are used to identify the optimal positions of fenestrations on the endograft. The laser machine then cuts fenestrations automatically and shortens the endograft if needed. The fenestrations are reinforced with nitinol wire and diameter-reducing ties are added to the endograft.

Our study provides evidence in support of PMEGs for primarily medically urgent cases of this nature. We report limited complications, including endoleak or aortic related mortality, with a median follow up of over 7 months.

Recent advancements in Wharton's jelly-derived mesenchymal stem cells (WJ-MSCs) fundamental research have produced promising data in the context of PAD management. As recent pilot studies have suggested WJ-MSCs efficacy in patients with end-stage PAD who lack alternative treatment option, WJ-MSCs may offer a novel therapeutic strategy for managing end-stage PAD. The abundance, ease of isolation, and absence of ethical concerns associated with WJ-MSCs facilitate their potential clinical use. However, randomized, appropriately powered clinical trials are necessary to comprehensively assess their safety and effectiveness. This review aims to summarize the molecular and cellular mechanisms underlying the emerging role of WJ-MSCs in critical limb ischemia.Clinical ImpactThis review establishes Wharton's Jelly MSCs (WJ-MSCs) as a paradigm-shifting therapy for end-stage critical limb ischemia (CLI).This review pioneers a translational roadmap for WJ-MSCs in CLI by integrating molecular mechanisms, preclinical models, and clinical outcomes.
