Recanalization of a chronic occlusion flow-diverter device in a patient with a paraclinoid giant aneurysm recurrence. Clinical observation.

Paraclinoid internal carotid artery (ICA) aneurysms are associated with a high mortality rate, which gradually increases without intervention. Surgical clipping or coiling of large aneurysms with inadequate neck and adductor artery expansion will not guarantee a successful outcome. Carotid surgical trapping or endovascular occlusion of the adductor artery can help to isolate the aneurysm from circulation, but it comes at the expense of sacrificing a major blood vessel responsible for significant cerebral perfusion.

Transvenous embolization of indirect carotid-cavernous fistula via puncture of the cubital vein and distal radial artery.

Carotid-cavernous fistula (CCF) is a pathologic communication between carotid arteries and cavernous sinus. The goal of endovascular treatment is to completely interrupt the carotid-cavernous communication with preserving normal blood flow in carotid arteries. Embolization can be performed via transarterial or transvenous access depending on anatomy and angioarchitecture of fistula.

[Endovascular embolization of arteriovenous fistula in a patient with hand ischemia].

We present a case report of atypical hand ischemia probably caused by a combination of venous insufficiency and steal syndrome in patient with arteriovenous fistula for hemodialysis. Unclear clinical symptoms may be due to severe trophic disorders (delayed treatment) or combination of two complications (steal syndrome and venous insufficiency). At the same time, we did not get any diagnostic data confirming organic injury of the upper limb veins or central veins.

The role of the mLDL-induced activation of the complement system classical pathway and C3 expression stimulation in atherosclerosis.

The role of modified low density lipoprotein in the activation of the classical pathway of the complement system and increasing expression C3 gene in human macrophages is described, role of these processes on the progression of atherosclerotic vascular lesions is considering.

Retrograde transvenous balloon-assisted Onyx embolization of mandibular arteriovenous malformation after hemorrhage.

Mandibular arteriovenous malformation (AVM) is a rare lesion, but it often can be presented with life-threatening bleedings. Endovascular treatment of mandibular AVMs has multiple approaches including transarterial embolization, transvenous embolization, direct puncture, and sclerotherapy. In this case study, we present a patient with mandibular AVM complicated by hemorrhage.
