破裂性出血乃由心脏或血管壁破裂所致。破裂可发生于心脏（如心壁瘤的破裂），也可发生于动脉，其成因既可为动脉壁本身的病变（如主动脉瘤），也可因动脉旁病变侵蚀动脉壁（如肺结核空洞对肺血管壁的破坏，肺癌、胃癌、子宫颈癌的癌组织侵蚀局部血管壁，胃和十二指肠慢性溃疡的溃疡底的血管被病变侵蚀）。静脉破裂性出血的原因除创伤外，较常见的例子是肝硬变时食管静脉曲张的破裂。毛细血管的破裂性出血发生于局部软组织的损伤。
脑瘤的破裂相对罕见，但因其会引发脑出血，所以是致命性的。
The rupture of a brain aneurysm is a relatively rare event but, as it causes bleeding in the brain, that event is a potentially devastating one.
病程越长，发生粘连、破裂、出血、坏死和感染的可能性越大。
The longer the course of disease, the more possibleadhesion, rupture, hemorrhage, necrosis and infection may happen.
