BACKGROUND: To predict wound healing in patients with critical limb ischemia(CLI) is ongoing issue. Currents methods like ankle-brachial index (ABI), color doppler and transcutaneous oxygen pressure (TCPO2 ), CT angiography are lacking in demonstrating regional perfusion. Indocyanine green angiography (ICGA) has the potential to provide regional perfusion information lacking in other methods. To demonstrate successes of revascularization procedure in CLI patients based on ICGA data this study was conducted...

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA), which has been increasingly used for the management of hemorrhagic shock, is a less invasive strategy for the management of patients with very severe hemorrhage. However, its effectiveness remains controversial. METHODS: This retrospective case series included trauma patients who underwent REBOA for hemorrhagic shock due to trauma in four Japanese tertiary care emergency centers from January 2013 to March 2017...

We aimed to analyze the effects of percutaneous transluminal angioplasty (PTA) of the superficial femoral artery (SFA) on arterial pulse waves (PWs). Altogether 24 subjects i.e. 48 lower limbs were examined including 26 treated lower limbs having abnormal ankle-to-brachial pressure index (ABI) (ABI<0.9 or ABI>1.3) and 22 non-treated lower limbs. The measurements were conducted in pre-, peri- and post-treatment phases as well as in follow-up visit after 1 month. Both ABI and toe pressures measured by standard equipment were used as reference values...

Critical limb ischemia (CLI) is a terminal stage of peripheral arterial disease that, in the absence of intervention, may lead to lower extremity amputation or death. Endovascular interventions have become a first-line approach to the management of CLI and have advanced considerably within the past decade. This review summarizes the types of percutaneous devices and the techniques that are available for the management of CLI and the data supporting their use. These include devices that establish and maintain vessel patency, including percutaneous transluminal angioplasty, drug-coated balloons, bare metal stents, drug-eluting stents, bioresorbable vascular scaffolds, and atherectomy; devices that provide protection from embolization; and, cell-based therapies...

BACKGROUND: Hemodialysis (HD) has been shown to be an independent predictor of poor outcomes after femoropopliteal revascularization procedures in patients with chronic limb-threatening ischemia. However, HD patients tend to have isolated infrageniculate disease, an anatomic risk factor for inferior patency. We aimed to compare outcomes for HD versus non-HD patients after infrageniculate open lower extremity bypass (LEB) and endovascular peripheral vascular interventions (PVIs). METHODS: Data from the Society for Vascular Surgery Vascular Quality Initiative database (2008-2014) were analyzed...

Despite recent advances in the treatment of Deep Vein Thrombosis (DVT) provided by Direct Oral Anticoagulants (DOAC), a substantial proportion of lower limb DVT patients will develop some degree of post-thrombotic syndrome (PTS) within 2 years. Systemic thrombolysis, although effective in reducing the risk of PTS and leg ulceration, is associated with a high risk of major bleeding, making it unsuitable for the vast majority of patients. A local approach, aimed at delivering the fibrinolytic drug directly into, or near to, the thrombus surface, is attractive because of the possibility of lowering of the administered drug dose, thus reducing the bleeding risks...

BACKGROUND AND PURPOSE: The thyrocervical trunk (TCT) is the second ascending branch of the subclavian artery. It is considered a 'border territory' between interventional vascular radiology and interventional neuroradiology because it gives rise to branches both cervical and to the upper limbs. We describe the TCT branches anatomy, the most frequent variants, and expose eight endovascular procedures performed through the thyrocervical trunk. METHODS: A retrospective review of all the interventional radiology procedures carried out through the TCT in our tertiary care center from August 2014 to January 2017 is presented...

The pathophysiology of atherosclerosis involves a diseased endothelium, lipid accumulation and low-grade inflammation. In later stages of coronary artery disease (CAD) and peripheral arterial disease (PAD), plaque rupture may induce atherothrombosis caused by fibrin formation and platelet activation, leading to vessel occlusion with subsequent organ damage such as myocardial infarction, stroke or limb ischaemia. Because of the high disease burden associated with CAD and PAD, there is a need for continuous vascular protection beyond currently available treatments including antiplatelet agents...
