血栓Thrombus · 腺胃 · 消化系统 · NTP ntp-0284
诊断要点：无论何时出现，血栓均应诊断并分级。血栓的严重程度分级取决于发生血栓的血管数量及血栓大小。
病变描述
供应胃壁的血管内血栓形成（Figure 2、Figure 4）可导致出血和坏死（Figure 1、Figure 3）。血栓可能起源于血管壁，也可能是来自其他部位（如心房或瓣膜）的血栓栓子所致。
诊断与分级建议（NTP 共识）
无论何时出现，血栓均应诊断并分级。血栓的严重程度分级取决于发生血栓的血管数量及血栓大小。在炎症和坏死区域血管内发现的小血栓，若看来是局部炎症过程所致，通常不予记录。继发于血栓的坏死区域内的出血，除非是显著病变，通常不予记录。若血栓导致组织坏死（梗死），则血栓和坏死均予记录并分级。

Comment：
Thrombosis in vessels ( Figure 2 and Figure 4 ) supplying the stomach wall can result in hemorrhage and necrosis ( Figure 1 and Figure 3 ). Thrombosis may originate in the vessel wall or may be the result of thromboemboli originating elsewhere, such as the atrium or valves.
Recommendation：
Whenever present, thrombi should be diagnosed and graded. The severity grade for thrombi depends on the number of vessels thrombosed and the size of the thrombi. Small thrombi found in vessels in areas of inflammation and necrosis are not usually recorded if they appear to have formed as result of the local inflammatory process. Hemorrhage in an area of necrosis secondary to a thrombus is not usually recorded unless it is a prominent lesion. If a thrombus results in necrosis (infarction) of the tissue, both the thrombus and the necrosis are recorded and graded.
