According to the World Health Organization, around 300 million people are affected by the pathological oedema of limbs. Lymphoedema is caused by partial or total obstruction of lymphatic collectors as a consequence of skin and deep soft tissue inflammation, trauma of soft tissues and bones, lymphadenectomy and radiation in cancer therapy.
Saphenous pulsation is the cyclical impulse of antegrade flow observed on colour duplex ultrasound after prolonged standing. It is a common observation in patients with saphenous reflux and is detected in the upper part of the great saphenous vein, remote from neighbouring arterial interference. Interest in pulsation has been renewed by its potential as a marker of severe chronic superficial venous insufficiency.
Eximo Medical has successfully completed a multicentre clinical trial for the purpose of obtaining CE approval for marketing in Europe. The results of the trial indicate that use of the Eximo system provides a safe, precise and highly efficacious solution in cases of partial blockage, complete blockage and severe calcification.
Use of dynamic flow reversal when performing transcervical carotid artery stent placement “demonstrated a significant reduction in embolisation to the brain” compared with transfemoral carotid artery stenting using distal filters, according to a Belgian study published in the Journal of Endovascular Therapy.
A study published in the Journal of Endovascular Therapy suggests that carbon dioxide flushing may be a solution for the “potentially underappreciated” problem of arterial air embolism in aortic endografting.
The Surfacer Inside-Out access catheter system (Bluegrass Vascular Technologies) has been successfully used in its first clinical case. The patient in question was facing life-threatening complications from end-stage renal disease.
Halfway through its Controversies, Challenges and Consensus cycle, the Charing Cross Symposium will examine this year the numerous and varied challenges currently facing the vascular and endovascular field. The Symposium will be held from 26 to 29 April 2016 at Olympia Grand, London, UK.
Studies have indicated that patterns of restenosis affect long-term outcomes following retreatment in the superficial femoral artery. Gary Ansel, OhioHealth/Riverside Methodist Hospital, Columbus, USA, presented results at the Leipzig Interventional Course (LINC; 26–29 January 2016, Leipzig, Germany) showing that, when in-stent restenosis occurs, it is more often focal with a drug-eluting stent (Zilver PTX, Cook Medical), whereas it is more diffuse with bare metal stents. The drug-eluting device, according to Ansel, yields less restenosis, less reintervention and reduced plaque burden.
The six-month results of the TOBA BTK (Tack optimised balloon angioplasty below the knee) study show that the Tack endovascular system (Intact Vascular) demonstrated high levels of primary patency, freedom from target lesion revascularisation and total freedom from amputation.
Hybrid operative thrombectomy achieves complete thrombus resolution in one operating room trip which results in reduced length of stay, bleeding complications and transfusions when compared with percutaneous treatments that use thrombolytic therapy. This can be achieved without sacrificing successful clinical or duplex results, according to data presented at the American Venous Forum (AVF; 24–26 February, Orlando, USA).
Deep vein thrombosis (DVT) refers to the formation of a blood clot (thrombus) in a deep vein in the leg. Deep vein thrombosis tends to occur in leg veins, such as the popliteal or femoral veins, as well as deep veins within the pelvis.
The formation of blood clots in the veins known as venous thromboembolism is the most common cause of preventable death in hospitals. A new study has now revealed that significant numbers of patients are not receiving recommended treatment to prevent these clots from forming - even after health care providers underwent educational programs.
One of the largest studies of its kind shows that stenting and surgery to reduce narrowing of the carotid artery and restore normal blood flow are equally effective at lowering the long-term risk of stroke.
Surgery for cardiovascular problems often requires the implantation of vascular grafts and stents to prop open failing or narrowed blood vessels. However, while this solves the immediate problem of restoring blood flow, it introduces the risk of blood clots.
Adding mechanical clot removal to clot-busting drugs could lower stroke survivors medical bills, decrease government healthcare as well as non-healthcare related costs, and increase the likelihood of the patient returning to work and participating in society, according to research presented at the American Stroke Associations International Stroke Conference 2016.
