lication is associated with acute arterial ischemia which results in a high limb loss and mortality.
Although endovascular peripheral vascular interventions (PVI) are typically limited to vessels above the knee in intermittent claudication (IC), some patients have concomitant or isolated infrapopliteal disease with IC. The benefits and risks of undergoing tibial intervention remain unclear in IC patients. The purpose of this study is to evaluate the prevalence and outcomes of infrapopliteal PVI for IC.

The Vascular Quality Initiative was queried for PVI procedures performed for IC between 2003 and 2018. Patients were divided into 3 groups isolated femoropopliteal (FP), isolated infrapopliteal (IP), and combined above and below knee interventions (COM). Multivariable logistic regression models identified predictors of minor and major amputation, as well as freedom from reintervention. Kaplan-Meier plots estimate amputation-free survival.

We identified 34,944 PVI procedures for IC. There were 31,110 (89.0%) FP interventions, 1,045 (3.0%) IP interventions, and 2,789 (8.0%) COM interventions. Kaplan-Meier rates. This observation may suggest the need for more careful patient selection when performing PVI in patients with IC where disease extends into the infrapopliteal level.
Anecdotal experience demonstrates the existence of patients with superiorly located carotid stenosis, neoplasms, or aneurysms where the mandible obstructs effective surgical access using standard techniques. As carotid pathology extends anatomically beyond the limits of standard operative technique, additional exposure becomes paramount to safely and effectively address the lesion. Double mandibular osteotomy (DMO) is one of several techniques to obtain additional exposure to high-carotid pathology; however, there is no large series to address the outcomes of patients undergoing this procedure.

A retrospective case series was performed for all patients undergoing surgery for carotid pathology from 2011-2019 that could not be approached with standard cervical incision. The primary predictor variable was high-anatomic carotid pathology necessitating DMO. The primary outcome variable was early and late complications sustained by patients.

Fifteen patients met study criteria and underwent 16 DMOs to access ure and surgical access to the distal internal carotid artery for repair of vascular pathology with acceptable outcomes and long-term complications compared with previously reported techniques. Because of the early complications realized with the DMO, we recommend the procedure for symptomatic patients with a high risk of failing medical therapy alone and not appropriate for endovascular treatment as well as those patients with tumors requiring surgical intervention.
Vascular calcifications have been identified as predictors of mortality in several cardiovascular diseases but have not been investigated in context of acute mesenteric ischemia. The aim of this study was to investigate the impact of vascular calcifications in patients with acute mesenteric ischemia.

Patients admitted for an acute mesenteric ischemia were retrospectively included. The presence of calcifications in the visceral aorta, the celiac trunk, the superior mesenteric artery, and the renal arteries was assessed on computed tomography scan images at the arterial phase. The calcification volumes were measured using the software Aquarius iNtuition Edition®.

The all-cause mortality was 55 out of 86 patients (63.9%) for a median follow-up of 3.5days (1-243). The survival rate of patients with calcification in the superior mesenteric artery was significantly lower than that of those without calcification (22% vs. 55.6%, P=0.019). Patients who died had significantly a higher frequency of calcifications in the superior mesenteric artery, the visceral aorta, the celiac trunk, and the renal arteries.

The presence of vascular calcifications in the superior mesenteric artery is associated with increased mortality in patients diagnosed with acute mesenteric ischemia. Further studies are required to identify the mechanisms underlying this association.

Effective amputation prediction may help inform appropriate early limb salvage efforts in military lower extremity (LE) arterial injury. The Mangled Extremity Severity Score (MESS) is the most commonly applied system for early amputation prediction but its utility in military trauma is unknown.

Retrospective cohort study of Iraq and Afghanistan casualties with LE arterial injury who underwent a vascular limb salvage attempt. Retrospectively assessed MESS was statistically explored as an amputation predictor and MESS component surrogates (mechanism, vascular injury characteristics, tourniquet use, and transfusion volume) were used to characterize limb injuries by presenting characteristics and evaluated for amputation prediction.

A total of 439 limbs were included with 99 (23%) amputations, 29 (7%) within 48 hr of injury. Median MESS was 5 (interquartile range 4-6) among salvaged limbs and 7 (5-9) among amputations (P<0.0001). An MESS cutoff of ≥7 had a better receiver operating characteristic sensitixisting scoring systems or the presenting characteristics available in this registry. Limb loss is predominantly late and likely because of factors not projectable at initial presentation.
Emerging evidence suggests that severe form of coronavirus disease 2019 (COVID-19) is mediated, in part, by a hypercoagulable state characterized by micro- and macro-vascular thrombotic angiopathy. Although venous thrombotic events in COVID-19 patients have been well described, data on arterial thrombosis (AT) in these patients is still limited. We, therefore, conducted a rapid systematic review of current scientific literature to identify and consolidate evidence of AT in COVID-19 patients.

A systematic search of literature was conducted between November 1, 2019, and June 9, 2020, on PubMed and China National Knowledge Infrastructure to identify potentially eligible studies.

A total of 27 studies (5 cohort, 5 case series, and 17 case reports) describing arterial thrombotic events in 90 COVID-19 patients were included. The pooled incidence of AT in severe/critically ill intensive care unit-admitted COVID-19 patients across the 5 cohort studies was 4.4% (95% confidence interval 2.8-6.4). Most of the patients were male, elderly, and had comorbidities.
