The Comparative Effects of Ticagrelor and Clopidogrel on Arterial Injury and In-Stent Restenosis and Thrombosis of Carotid Artery in Atherosclerotic Rabbits
Introduction - Carotid artery angioplasty and stenting (CAS) is expanding as a method to treat carotid artery disease worldwide. Until now a combination of aspirin and clopidogrel has been used pre and post CAS. Ticagrelor, a P2Y (12) inhibitor, has an important role in coronary artery angioplasty. There is lack of evidence about the impact of ticagrelor on carotid artery disease and CAS. Our aim was the comparative evaluation of ticagrelor and clopidogrel on carotid balloon-injury and in-stent restenosis (ISR) and thrombosis in rabbits.
We present a strategy to retrieve the extracranial thrombus using the "stent retriever assisted vacuum-locked extraction" (SAVE) method, which initially was described for the intracranial vasculature. The extracranial SAVE (eSAVE) method could be an additional tool for the treatment of acute tandem lesions. PMID: 31358489 [PubMed - as supplied by publisher]
CONCLUSIONS: Down-regulating miR-223 could be a potential therapeutic approach to prevent restenosis after angioplasty. PMID: 31284864 [PubMed - as supplied by publisher]
CONCLUSIONS: The result suggests that miR-140-3p regulates ASMC function via targeting C-Myb and BCL-2 in the process of ISR in PAD. The novel findings may offer a hopeful therapeutic target for human PAD. PMID: 29760303 [PubMed - as supplied by publisher]
Conclusion: Acute carotid stent thrombosis (ACST) can have devastating effects on the survival of the patient. For ACST when the stent does not fully adhere to the blood vessel, a mechanical approach should be a feasible solution to the problem.Intervent Neurol 2018;7:265 –270
[Image from unsplash.com]From the FDA’s clearance of Covalon’s film-drape to Bioventus launching its study, here are seven medtech stories we missed this week but thought were still worth mentioning. 1. FDA clears Covalon’s MediClear OTC surgical film-drape Covalon announced in a Sept. 21 press release that the FDA has cleared its MediClear PreOp to market in U.S. hospitals, clinic and directly to patients without a prescription. The MediClear PreOp is a breathable, transparent, self-adhesive, silicone barrier film-drape that can conform to a patient’s skin at a planned incision or insertion si...
CONCLUSIONS: These results indicate that CYGB is expressed in vessels primarily in differentiated medial VSM cells where it regulates neointima formation and inhibits apoptosis after injury. PMID: 28798140 [PubMed - as supplied by publisher]
Conclusion This is a technical note demonstrating the feasibility of a new device to deploy a flow diverter, aiming to improve wall apposition and stent configuration without the need of additional devices or exchange manoeuvres. PMID: 28604183 [PubMed - in process]
CONCLUSIONS: Our results demonstrate that JAK3 mediates SMC proliferation and survival during injury-induced vascular remodeling, which provides a potential therapeutic target for preventing neointimal hyperplasia in proliferative vascular diseases.

Objectives: Interventions such as balloon angioplasty can cause vascular injury leading to platelet activation, thrombus formation, and inflammatory response. This induces vascular smooth muscle cell activation and subsequent re-endothelialization with expression of αvβ3-integrin by endothelial cells and vascular smooth muscle cell. Thus, poly-N-butylcyanoacrylate microbubbles (MBs) targeted to αvβ3-integrin were evaluated for monitoring vascular healing after vessel injury in pigs using molecular ultrasound imaging. Materials and Methods: Approval for animal experiments was obtained. The binding spe...
CONCLUSION: This result shows that mechanical clot disruption, intrasinus thrombolysis and reconstruction of wall sinuses with stenting can be an endovascular option in the severe form of CVST with intracerebral hemorrhage and rapid worsening of neurological symptoms. Although this type of treatment can re-channel the occluded sinuses, further comparative and randomized studies are needed to clarify its efficacy versus other therapeutic modalities.
