Previous studies of venous anatomy lack the detail of their arterial counterparts due to (i) the technical challenge of retrograde perfusion against competent valves and (ii) anterograde venous perfusion that fails to capture significant portions of the area of interest. A novel technique, retrograde hydrogen peroxide (H2O2) priming, dilates veins ...

Cutaneous polyarteritis nodosa (CPN) is a rare vasculitis affecting the small-and medium-sized arteries in the reticular dermis and subcutaneous tissue. CPN should be distinguished from systemic polyarteritis nodosa (PAN), which is an aggressive systemic vasculitis with internal organ involvement. Extracutaneous findings of CPN include fever, myalgia, arthralgia, and neuropathy.(1) In ...

As neuroendovascular interventions for both ruptured and unruptured intracranial aneurysms have come to the forefront, careful follow-up and strategies for retreatment of aneurysmal recurrences have become increasingly important. Endovascular approaches have also proven to be valuable adjuncts for managing recurrent aneurysms previously treated by open microsurgical approaches. Fortunately, retreatment of ...

The availability of intra-arterial hepatic therapies (radio and/or chemo-embolisation, intra-arterial hepatic chemotherapy) has convinced radiologists to perfect their knowledge of the anatomy of the liver arteries. These sometimes, complex procedures most often require selective arterial catheterization. Knowledge of the different arteries in the liver and the peripheral organs is therefore ...

Traditionally abdominal aortic calcification (AAC) has received less intensive study than coronary artery calcification. The widespread use of abdominal imaging has however encouraged recent investigation of this problem. Human association studies suggest that older age, chronic kidney disease and osteoporosis are the most important risk factors for AAC. AAC severity ...

Arterial calcification (AC) is a hallmark of many serious diseases, including atherosclerosis, chronic kidney disease, and diabetes. AC may also develop as a side-effect of therapy with anticoagulants, such as warfarin which is widely used for prophylaxis of thrombosis. In our studies, we established the relation between warfarin-induced AC and ...

Paraplegia remains the most devastating complication after thoracic and thoracoabdominal aortic aneurysm (TAA/A) repair. The collateral network (CN) concept of spinal cord perfusion suggests segmental artery (SA) occlusion to mobilize redundant intraspinal and paraspinal arterial sources and ultimately trigger arteriogenesis, leading to spinal cord blood flow restoration within 96 to ...
