Retrograde Femoral Access Flipped Antegrade Technique and its Effect on Patient Outcomes Following Lower Extremity Angiography.

Background: Common femoral artery access is a critical step in the endovascular treatment of peripheral artery disease. Traditionally, access is obtained either by a retrograde approach from the contralateral leg with an "up-and-over" aortic bifurcation technique, or in an antegrade fashion in the ipsilateral leg. Retrograde arterial access flipped antegrade in the ipsilateral femoral artery incorporates the technical ease of retrograde access (RA) with mechanical advantages of antegrade access (AA).

Analysis of Presentation and Outcomes in Acute Limb Ischemia Patients During COVID-19 State of Emergency.

Background: During the COVID-19 pandemic, cardiovascular patients were found to be presenting to hospitals with myocardial infarctions and cerebrovascular accidents at progressed disease states. We noticed a parallel in acute limb ischemia (ALI) patients presenting during Massachusetts' COVID-19 State of Emergency declaration. We question whether patients developed a hesitancy to seek medical attention at hospitals due to fear of COVID-19.

Peak systolic velocity and color aliasing are important in the development of duplex ultrasound criteria for external carotid artery stenosis.

Objective: The external carotid artery (ECA) serves as a major collateral pathway for ophthalmic and cerebral artery blood supply. It is routinely examined as part of carotid duplex ultrasound, but criteria for determining ECA stenosis are poorly characterized and typically extrapolated from internal carotid artery data. This is despite the fact that the ECA is smaller in diameter, with a higher resistance and lower volume flow pattern.

Blunt traumatic celiac artery avulsion managed with celiac artery ligation and open aorto-celiac bypass.

Traumatic celiac artery injuries are rare and highly lethal with reported mortality rates of 38-62%. The vast majority are caused by penetrating trauma with only 11 reported cases due to blunt trauma (Graham et al., 1978; Asensio et al.

Eversion Femoral Endarterectomy for Iliofemoral Occlusive Disease: A Description of Technique and Series of Cases.

Background: Eversion endarterectomy (EE) is a well-described technique for the treatment of extracranial cerebrovascular disease. Longitudinal arteriotomy and closure with patch angioplasty is the standard for infrainguinal arterial occlusive disease in the iliofemoral segment. A potential drawback of this technique is the introduction of exogenous material into the field.
