急性腹主动脉闭塞合并双肾动脉闭塞1例临床分析

目的探讨急性腹主动脉闭塞合并双肾动脉闭塞的病因与抢救措施.方法对突然出现腰腹痛和双下肢疼痛伴麻木4 h的患者行腹主动脉造影,造影证实该患者为腹主动脉合并双肾动脉完全闭塞,行介入治疗和清栓术治疗.结果清除部分血栓,患者恢复血流5 min后发生高血钾,引发心脏骤停死亡.结论急性腹主动脉闭塞合并双肾动脉闭塞死亡率高,主要死因是心脏毒性物质的吸收、高血钾、酸中毒、肾衰竭致心脏骤停,抢救成功的关键是尽早开通患者闭塞血管.

Clinical Analysis on One Case of Acute Occlusion of the Abdominal Aorta with Concomitant Bilateral Renal Artery Occlusion

Objective To investigate the cause and rescue measures of the acute abdominal aorta occlusion with bilateral renal artery occlusion. Method The patient suffered suddenly from lumbar and abdominal pain and the lower limbs pain with numbness lasting for 4 hours, and was confirmed to be the acute occlusion of the abdominal aorta and bilateral renal artery by abdominal aorta angiography. The patient was treated by interventional therapy. Results The part of blood clots were removed from the abdominal aorta lesions. The blood flow was restored after 5 mins, the patient died of hyperkalemia and cardiac arrest. Conclusion The mortality rate of the acute abdominal aorta occlusion with bilateral renal artery occlusion is very high. The main cause of death is the cardiac arrest caused by the absorption of toxic substances, hyperkalemia, acidosis and renal failure. It is the key of successful rescue to open the occluded blood vessels as soon as possible.
