Characteristics of atherosclerosis in femoropopliteal artery and its clinical relevance.

Atherosclerosis 2021 Sep 11;335:31-40. Epub 2021 Sep 11.

Department of Vascular Diseases, University Medical Centre Ljubljana, Zaloška c. 7, 1525, Ljubljana, Slovenia; Division of Internal Medicine, Faculty of Medicine, University of Ljubljana, Slovenia.

Atherosclerosis is a systemic disease with different faces. Despite identical or similar pathogenetic mechanisms, atherosclerotic lesions and their clinical manifestations vary in different parts of the vascular system. Peripheral arterial disease (PAD) represents one of the most frequent clinical manifestations of atherosclerosis with predominant location in the superficial femoral artery (SFA). Read More

Wall shear stress mapping for human femoral artery based on ultrafast ultrasound vector Doppler estimations.

Med Phys 2021 Sep 15. Epub 2021 Sep 15.

Department of Biomedical Engineering, National Cheng Kung University, Taiwan.

Purpose: Wall shear stress (WSS), a type of friction exerted on the artery wall by flowing blood, is considered a crucial factor in atherosclerotic plaque development. Currently, achieving a reliable WSS mapping of an artery noninvasively by using existing imaging modalities is still challenging. In this study, a WSS mapping based on vector Doppler flow velocity estimation was proposed to measure the dynamic WSS on the human femoral artery. Read More

Endovascular therapy for severely calcified plaque at the superficial femoral artery using myocardial biopsy forceps.

CVIR Endovasc 2021 Sep 15;4(1):69. Epub 2021 Sep 15.

Department of Cardiovascular Medicine, Toho University Faculty of Medicine Graduate School of Medicine, Tokyo, Ota-ku, Japan.

Background: Currently, the success rate of EVT for treating CTO of the SFA is high; however, EVT is still found to be insufficient in treating CTOs with severely calcified lesions. Even if the guidewire crosses the lesion, the calcifications may still cause difficulties during stent expansion.

Main Text: A 78-year-old male had been reported to have intermittent claudication with chronic total occlusion (CTO) of the right superficial femoral artery (SFA). Read More

Effects of selective breeding for voluntary exercise, chronic exercise, and their interaction on muscle attachment site morphology in house mice.

J Anat 2021 Sep 14. Epub 2021 Sep 14.

Department of Evolution, Ecology, and Organismal Biology, University of California, Riverside, Riverside, California, USA.

Skeletal muscles attach to bone at their origins and insertions, and the interface where tendon meets bone is termed the attachment site or enthesis. Mechanical stresses at the muscle/tendon-bone interface are proportional to the surface area of the bony attachment sites, such that a larger attachment site will distribute loads over a wider area. Muscles that are frequently active and/or are of larger size should cause attachment sites to hypertrophy (training effect); however, experimental studies of animals subjected to exercise have provided mixed results.

Surgical and oncologic outcomes following arterial resection and reconstruction for advanced solid tumors.

J Surg Oncol 2021 Sep 8. Epub 2021 Sep 8.

Division of Surgical Oncology, UC Davis Comprehensive Cancer Center, Sacramento, California, USA.

Background And Objectives: Although arterial involvement for advanced tumors is rare, vascular resection may be indicated to achieve complete tumor resection. Given the potential morbidity of this approach, we sought to evaluate perioperative outcomes, vascular graft patency, and survival among patients undergoing tumor excision with en bloc arterial resection and reconstruction.

Methods: From 2010 to 2020, we identified nine patients with tumors encasing or extensively abutting major arterial structures for whom en bloc arterial resection and reconstruction was performed. Read More

Endovascular recanalization of chronic total occlusions of the native superficial femoral artery after failed femoropopliteal bypass in patients with critical limb ischemia.

CVIR Endovasc 2021 Sep 7;4(1):68. Epub 2021 Sep 7.

Radiology Division, Department of Experimental and Clinical Medicine, Magna Graecia University of Catanzaro, University Hospital Mater Domini, Viale Europa, 88100, Catanzaro, Italy.

Background: Femoropopliteal bypass occlusions are a significant issue in patients with critical limb ischemia and chronic total occlusion of the native superficial femoral artery, which challenges vascular surgeons and interventional radiologists. Performing a secondary femoropopliteal bypass is still considered the standard of care, although it is associated with a higher complication rate and lower patency rate in comparison with primary bypass. Over the past few years, angioplasty has been commonly used, with the development in endovascular technologies, to treat chronic total occlusions of the native superficial femoral artery, with a good technical success rate and clinical prognosis.

Case report: End of life care via a mid-thigh femoral midline catheter.

J Vasc Access 2021 Aug 31:11297298211043410. Epub 2021 Aug 31.

PICC Excellence, Inc, Chief Executive Officer, Hartwell, GA, USA.

Maintaining peripheral vascular access represents a major challenge for medical providers and patients leading to the emergence of ultrasound guided vascular access teams. Upper extremity peripheral vascular access options are often limited in the chronically ill patient population with end stage cancer, patients with severe contractures, tracheostomies, and feeding tubes and patients referred for palliative care are just some examples of patients who live with difficult access. The following is a case description of a mid-thigh superficial femoral vein midline catheter for comfort care medications in a patient with exhausted peripheral vasculature on hospice. Read More

Feasibility of using the balloon backed-up microcatheter technique to treat superficial femoral artery occlusion under extra-vascular ultrasound guidance via radial access.

Cardiovasc Revasc Med 2021 Aug 16. Epub 2021 Aug 16.

Department of Cardiology, Saiseikai Yokohama City Eastern Hospital, 3-6-1 Shimosueyoshi, Tsurumi-ku, Yokohama City, Kanagawa 230-0012, Japan. Electronic address:

Background: Endovascular treatment (EVT) of superficial femoral artery (SFA) lesions that can be reached through transradial access (TRA) has often been performed due to its low invasiveness. For complex lesions such as chronic total occlusion (CTO) treated via TRA, EVT is still challenging due to poor device backup and guidewire operability. However, TRA might be preferred in patients with a high risk of bleeding or restricted access sites. Read More

Implications of zonal architecture on differential gene expression profiling and altered pathway expressions in mandibular condylar cartilage.

Sci Rep 2021 Aug 19;11(1):16915. Epub 2021 Aug 19.

Division of Paediatric Dentistry and Orthodontics, Faculty of Dentistry, The University of Hong Kong, 34 Hospital Road, Hong Kong, SAR, China.

Mandibular condylar cartilage (MCC) is a multi-zonal heterogeneous fibrocartilage containing different types of cells, but the factors/mechanisms governing the phenotypic transition across the zones have not been fully understood. The reliability of molecular studies heavily rely on the procurement of pure cell populations from the heterogeneous tissue. We used a combined laser-capture microdissection and microarray analysis approach which allowed identification of differential zone-specific gene expression profiling and altered pathways in the MCC of 5-week-old rats.
