  Hepatopulmonary syndrome (HPS) is characterized by the triad of abnormal arterial oxygenation caused by intrapulmonary vascular dilatations (IPVDs) in the setting of liver disease, portal hypertension, or congenital portosystemic shunts HPS is most commonly seen in patients with chronic liver disease, particularly those with portal hypertension ● Chronic liver disease  – Chronic liver disease (CLD) of virtually any etiology including congenital liver disease that limit venous flow to the lung (eg, cavopulmonary shunt ) and Abernethy malformation (congenital portosystemic shunt ) can be associated with HPS, particularly when CLD is complicated by portal hypertension. ● Portal hypertension  – HPS is most commonly seen in patients with portal hypertension in association with chronic liver disease but can also occur in those who have portal hypertension without underlying liver disease In patients with liver disease, no risk factors other than the presence of portal ...

  ischemia should always be considered in the differential diagnosis of acute hepatitis, along with more common causes such as viral infection, drugs, toxins, autoimmunity, and metabolic disorders. The typical pattern of liver biochemical tests consists of a rapid rise in serum aminotransferase levels associated with an early massive rise in lactate dehydrogenase ( LDH ) levels. Peak aminotransferase levels are typically 25 to 250 times the upper limit of normal and are reached within one to three days of the hemodynamic insult . In the absence of ongoing hemodynamic instability, aminotransferase levels subsequently decline steadily, usually returning to normal within 7 to 10 days . The serum bilirubin level infrequently rises above four times the upper limit of normal, usually beginning its rise after aminotransferase levels have begun to decline. Serum ALP levels are rarely higher than twice the upper limit of normal. Hepatic synthetic function usually remains normal or ...

 Hastanın öyküsünde  potansiyel hepatotoksin (alkol ve ilaçlar dahil) maruziyeti sorgulanmalıdır.   Önemli düzeyde alkol tüketimini, en az iki yıllık bir süre boyunca erkeklerde haftada ortalama >210 gram veya kadınlarda haftada >140 gram alkol tüketimi olarak tanımlıyoruz Hastalar  sağ taraflı kalp yetmezliği (konjestif hepatopati), diabetes mellitus, cilt pigmentasyonu, artrit, hipogonadizm ve dilate kardiyomiyopati (hemokromatoz) ve obezite (alkolsüz yağlı karaciğer hastalığı), hamilelik (safra kesesi taşları), inflamatuar barsak hastalığı (primer sklerozan kolanjit, safra kesesi taşları), erken başlangıçlı amfizem (alfa-1 antitripsin eksikliği), çölyak hastalığı ve tiroid hastalığı gibi tablolar yönünden sorgulanmalıdır. Son olarak, hastalar hepatotoksinlere mesleki maruziyet veya eğlence amaçlı kullanım (örneğin, mantar toplama) açısından  sorgulanmalıdır R faktörü  ,yüksek aminotransferaz ve alkalen fosfatazı olan hastalarda olası karaciğ...
