Collateral Formation

Portosystemic collateral formation in cirrhosis plays an important part in events that define the natural history in affected patients. A detailed understanding of collateral anatomy and hemodynamics in cirrhotics is essential to envisage diagnosis, management, and outcomes of portal hypertension. In this review, we provide detailed insights into the historical, anatomical, and hemodynamic aspects to portal hypertension and collateral pathways in cirrhosis with emphasis on the various classification systems.

AbstractCervical carotid and vertebral artery traumatic injuries can have a devastating natural history. This article reviews the epidemiology, mechanisms of injury, clinical presentation, and classification systems pertinent to consideration of endovascular treatment. The growing role of modern endovascular techniques for the treatment of these diseases is presented to equip endovascular surgeons with a framework for critically assessing patients presenting with traumatic cervical cerebrovascular injury.

Comprehensive List

A comprehensive list of the taxons dedicated to Grigore Antipa by collaborators, science personalities who appreciated his work was constituted from surveying the natural history or science museums or university collections from several countries (Romania, Germany, Australia, Israel and United States). The list consists of 33 taxons, with current nomenclature and position in a collection. Historical aspects have been discussed, in order to provide a depth to the process of collection dissapearance during more than one century of Romanian zoological research. Natural calamities, wars and the evictions of the museum’s buildings that followed, and sometimes the neglection of the collections following the decease of their founder, are the major problems that contributed gradually to the transformation of the taxon/specimen into a historical landmark and not as an accessible object of further taxonomical inquiry.

Background/Aims: One hallmark of chronic liver disease in patients with portal hypertension is the formation of portal-systemic collaterals in which angiogenesis has a fundamental role. We studied patients with chronic liver disease undergoing liver transplantation to correlate levels of circulating angiogenic factors in portal and peripheral circulation with portal pressure and portal-systemic collaterals. Methods: Sixteen patients who underwent liver transplantation were enrolled. During transplant surgery, we determined portal venous pressure and portal-systemic collateral formation. We determined angiogenics mediator levels in systemic and portal plasma. Peripheral plasma from healthy donors was measured as controls. Results: Vascular endothelial growth factor (VEGF)-R1 and 2, Ang-1 and 2, Tie2, FGF- 1 and 2, CD163, PDGFR-β, PDGFsRα, PDGF-AB and BB, CD163, TGF-β VASH-1 levels were significantly different in the controls in comparison to cases. Significantly decreased portal venous levels of Ang-1, FGF-1, PDGF-AB/BB, and CC were observed in patients with higher portal pressure. Peripheral VEGF, Ang-1, pPDGF-AB, BB, and CC were significantly decreased in patients with more severe collateral formation. While peripheral VEGF-R1 was higher in patients with severe collateral formation. For portal circulation, VEGF, Ang-1, ­pPDGF-AB, BB, and CC were significantly decreased in patients with more severe collateral formation Conclusions: Angiogenesis factors correlated with portal pressure and collateral formation and different patterns of circulating angiogenesis mediators were found in peripheral and portal blood of patients with chronic liver disease. These results support the importance of angiogenic pathways in cirrhosis and portal hypertension and highlight areas for further study to identify clinically useful noninvasive markers of portal pressure and collateral formation.
