RESUMEN
Acute aortic dissection type A(AADA) has a critical condition and high mortality. One of the most severe complications is malperfusion syndrome. AADA with malperfusion syndrome affects almost all vascular beds, including the brain, coronary artery, viscera, limb branches, and so on. The incidence and severity of malperfusion vary from organ to organ. Clinically, malperfusion must be diagnosed and treated in time. At present, there is no consensus on the clinical management strategy of AADA complicated with malperfusion syndrome. In this review, we discussed the related research progress of AADA involved with malperfusion syndrome to provide some guidance for clinical practice.
RESUMEN
Objective To analyze and compare of regional citrate anticoagulation (RCA),low molecular weight heparin and hep-arin-free in severe sepsis patients with thrombocytopenia CRRT treatment effect and complication of the situation.Methods Retro-spective analysis of 3 6 patients admitted to ICU CRRT therapy of severe sepsis in patients with thrombocytopenia was made.Nine patients were given RCA,1 4 patients were given low-molecular-weight heparin calcium and 1 3 patients were given no heparin anti-coagulation programme.And then observation of three groups of CRRT treatment of coagulation function in patients with platelet depletion,blood,bleeding conditions,filter effects,filter usage time,and 15-day,30-day mortality were made.Results In RCA group and heparin-free group,coagulation blood features was significantly superior to low-molecular liver pigment calcium group (P0.05)between RCA group and heparin-free group coagulation in blood features. Bleeding rate and platelet consumption in RCA group were significantly lower than that in heparin-free group and low molecular liv-er pigment group(P0.05).Conclusion Severe sepsis in patients with thrombocytopenia in CRRT applications of regional citrate anticoagu-lation could reduce the risk of hemorrhage,reduced platelet consumption and longer filter usage time.
