即使具有可达性，异位静脉曲张也不可能完全闭塞，因为存在与全身或肠系膜静脉系统的交通支。
Moreover, variceal embolization has the risk of inherent complications, such as propagative thrombus or paradoxical systemic embolization.
此外，静脉曲张栓塞有发生固有并发症的风险，如传播性血栓或矛盾的全身性栓塞（进入肺动脉还是周围动脉？）。
Although a recent meta-analysis showed a trend favoring variceal embolization along with TIPS for ectopic variceal bleeding, the evidence is insufficient to recommend the same routinely[57].
虽然最近的一项荟萃分析显示，有利于静脉曲张栓塞和TIPS治疗异位静脉曲张出血的趋势，但证据不足以推荐相同的常规[57]。
However, when the target PSPG could not be achieved after TIPS stent placement and in whom the ectopic varices continue to be opacified on completion splenoportogram, concomitant variceal embolization may be appropriate.
然而，当TIPS支架放置后无法实现目标PSPG，并且异位静脉曲张在完成后继续显影时，同时进行静脉曲张栓塞可能是合适的。
Variceal embolization alone can be offered to patients in whom TIPS is contraindicated due to advanced cirrhosis or overt HE (Figure (Figure55).
对于晚期肝硬化或明显HE导致TIPS禁忌的患者，可单独进行静脉曲张栓塞（下图）。
