Unlabelled: An aneurysm of the medium arteries is one of the major complications of Kawasaki syndrome. Eleven cases of giant coronary aneurysm have been reported.
Case Report: We report a new case in a nine-month-old child. Ischemia of the left hand was the first symptom. Diagnosis was made 30 days later. Anticoagulant and fibrinolytic treatments did not prevent necrosis of four fingers.
Conclusion: The prognosis of Kawasaki disease depends on early diagnosis and management. Infants younger than seven months of age are more susceptible to developing coronary and midartery aneurysms, which therefore justifies a close observation during the acute phase and later on. In the case of a coronary artery aneurysm, Doppler echography of the upper and lower limbs is mandatorily recommended. Anticoagulant therapy should be started once the diagnosis of mid-artery aneurysms is made. Ischemia of the extremities can lead to necrosis and amputation. Until now, anticoagulants, vasodilators and fibrinolytic agents were not proven to be effective.

Spontaneous true brachial artery aneurysm: A case report from Somalia.
Int J Surg Case Rep
January 2025
Introduction And Importance: True brachial artery aneurysms are rather uncommon, due to their number of etiological factors. Besides inducing symptoms such as hand or digit ischemia, they may present as pulsative tumefactions and cause pain or paresthesias through nerve impingement. The diagnosis is based on duplex ultrasonography, CTA in the operational planning phase, and a physical examination.

Remote Ischemic Preconditioning (RIPC) is a therapy characterized by repeated bouts of limb ischemia and reperfusion. RIPC protects against ischemia-reperfusion injury (IRI), and preclinical studies suggest that this is mediated through release of endogenous opioids. We aimed to interrogate the role of endogenous opioids in RIPC-signaling in humans, using an arm model of IRI.

We aimed to test whether angiotensin II infusion during intermittent hemodialysis is safe, feasible, and effective in the attenuation of muscle cramps.
Methods: We performed a pilot, single-blinded, randomized crossover trial of patients receiving intermittent hemodialysis who frequently experience intradialytic muscle cramps.

Objective: Brachial artery aneurysms are rare entities that have typically been associated with trauma, infection, arterio-venous fistula creation or connective tissue disorders. These aneurysms are often asymptomatic, but they can also cause local tenderness or thrombo-embolic events. Due to the very low incidence of true brachial artery aneurysms, there are no standardized guidelines on their optimal management.

Introduction/aim: The partial deployment technique (PDT) is an unconventional option of T-branch deployment to allow target arteries (TAs) cannulation/stenting from the upper arm access, in case of narrow (NPA: <25mm) or severely angulated (APA: >60°) aorta. Aim of this study was to report outcomes of the endovascular repair of complex aortic (c-AAAs) and thoracoabdominal (TAAAs) aneurysms by T-branch and PDT.
Methods: All consecutive patients underwent urgent endovascular repair of c-AAAs and TAAAs by T-branch (Cook-Medical, Bloomington, IN, US) and PDT from 2021 to 2023 were analyzed.
