Since the era of the widespread introduction of antibiotics into the human sphere of activity, the problem of antimicrobial resistance has become an urgent and very important topic around the world. Recently, coagulasonegative staphylococci (CoNS), which are representatives of opportunistic microorganisms of the microbiome of the skin and mucous membranes of healthy people, have made a certain contribution to its progression. For a long time, they did not pose a threat to patients, but in recent decades among microorganisms they have been seeded in more than two-thirds of patients with postoperative mediastinitis, catheter-associated infections, as well as from wounds of the neck vessels and the inguinal region separated by pacemaker beds.

Arterial variations in the upper limb are of significant clinical importance, especially in procedures such as venepunctures, coronary artery bypass grafts, trauma reconstructive surgeries, brachial plexus nerve blocks, and breast reconstructions. This report presents previously undocumented arterial variations in the upper limbs in a 95-year-old female cadaveric donor. We observed bilateral superficial ulnar arteries originating at the cubital fossa, deviating from the previously reported origin at the proximal brachial artery.

Spontaneous thrombosis of intracranial aneurysms is rare. Spontaneous regression of unruptured small saccular aneurysms is even more rare. A 76-year-old woman with a history of hypertension and dyslipidemia was referred for evaluation of an unruptured intracranial aneurysm.

As the number of cerebral aneurysms treated with flow diverters continues to increase, it is important to understand what factors influence not only thrombus formation within the aneurysm cavity but also fibrin accumulation across the device and its associated disruption and blockage of the inflow stream. Both processes contribute to the eventual occlusion of the aneurysm or its continued patency and incomplete occlusion which may require future re-treatment. To investigate fibrin accumulation on flow diverters placed across the neck of cerebral aneurysms, a previously developed computational model that couples flow and fibrin dynamics is used in combination with experimental in vitro models of cerebral aneurysms treated with flow diverters.
