Brachial artery aneurysms are rare, mostly consisting of false ones secondary to infectious, traumatic, or iatrogenic arterial lesions. True aneurysms of the brachial artery are even more uncommon. Here, we report a case of a 40-year-old fisherman, without any pathological antecedent, who presented with a painful pulsatile mass of the left anterior arm. There was a slight edema with no ischemic signs. The computed tomographic angiography revealed a true 3.7 × 4.2 × 6 cm aneurysm of the distal brachial artery, partially thrombosed, which extended to the bifurcation. A surgical repair was indicated. Intervention consisted of an aneurysmectomy with interposition of an autologous reversed bifurcated saphenous vein graft. Early outcome was good and a 1-year follow-up showed a patent graft with no aneurysmal recurrence. A review of the literature on this rare location of true artery aneurysm and treatment options is outlined in this work.

Digital Ischemia Secondary to Ulnar Artery Puncture Successfully Treated by Brachial Plexus Block: A Case Report.

After vascular puncture and catheterization, arteries can have many complications that impede blood flow such as vasospasm, thrombosis, and emboli generation, among other complications. Treatment depends on severity of ischemic symptoms and can range from as mild as applying local heat packs to surgical thrombectomy. We present a case of digital ischemia secondary to vascular puncture that was successfully treated with a supraclavicular nerve block, resulting in the vascular surgery team canceling an emergent surgery.

Background: Arteriovenous fistulas (AVFs) in kidney transplant recipients are sometimes closed, either as a policy or due to complications. We collected data on the incidence of complications after AVF closure in a national cohort of transplanted patients.
Methods: Patients who received a kidney transplant between 2000 and 2015 and had a functional AVF that was later ligated or extirpated were included.
Association of Post-procedure Ankle-Brachial Index with Outcomes Following Drug-Coated Balloon Angioplasty in Femoropopliteal Artery Disease.

Endovascular treatment of femoropopliteal artery (FPA) disease with Drug-coated balloons (DCBs) may face complications such as arterial recoil, dissection, and residual stenosis. Angiography has limited accuracy for evaluating blood flow through revascularized target lesions. Thus, there is a need for post-procedure hemodynamic assessment in treated limbs.

Relationships between gonadotropins, sex hormones, and vascular structure and function in adolescents of varying weight statuses have not been fully investigated. In the present study, we examined associations among these in female and male adolescents with normal weight or obesity. We performed a cross-sectional analysis of adolescents ( = 58; 12-<18 years) grouped according to BMI percentile (BMI%) into normal weight (5th-<85th BMI%; = 25) and obesity (≥95th BMI%; = 33) categories.

Purpose: The present study aimed to compare the impacts of different exercise types on cardiovascular health and executive function in sedentary young individuals, and to determine the associations between cardiovascular function and executive function (EF) after exercise.
Methods: Sixty-three sedentary participants were randomly divided into high-intensity interval training (HIIT), moderate-intensity continuous training (MICT), resistance exercise (RE), and control groups. Macro- and microvascular endothelial function were assessed using brachial artery flow-mediated dilation and fingertip reactive hyperemia index, respectively.
