Abstract:
Splenic venous hypertension or left-sided portal hypertension is a rare condition caused by an obstruction of the splenic vein. Usually, it presents with upper gastrointestinal bleeding in the absence of liver disease. Etiologies can be classified based on the mechanism of development of splenic vein hypertension: compression, stenosis, inflammation, thrombosis, and surgically decreased splenic venous flow. Diagnosis is established by various imaging modalities and should be suspected in patients with gastric varices in the absence of esophageal varices, splenomegaly, or cirrhosis. The management and prognosis vary depending on the underlying etiology but generally involve reducing splenic venous pressure. The aim of this review was to summarize the etiologies of splenic venous hypertension according to the mechanism of development.
摘要:
脾静脉高压或左侧门静脉高压是由脾静脉阻塞引起的罕见疾病。通常,在没有肝病的情况下,它表现为上消化道出血。病因可以根据脾静脉高压的发展机制进行分类:压迫,狭窄,炎症,血栓形成,手术减少脾静脉流量。诊断通过各种影像学方式确定,并且在没有食管静脉曲张的胃静脉曲张患者中应怀疑。脾肿大,或肝硬化。治疗和预后因潜在病因而异,但通常涉及降低脾静脉压。这篇综述的目的是根据发展机制总结脾静脉高压的病因。
