The occurrence of ischaemic changes, arterial occlusion, and other complications which may follow percutaneous arterial cannulation was assessed in a survey of 155 patients. No patient complained of or had signs of ischaemic damage though signs of arterial occlusion were found in 33 patients (22%). These signs were significantly more common after periods of cannulation greater than six hours (43%) than after less than six hours cannulation (17%). During recovery from occlusion all patients had palpable pulsation over the artery even though blood flow seemed to be absent. By the end of follow-up blood flow had returned in 19 of the 33 occluded arteries.
在一项对155名患者的调查中,评估了经皮动脉插管后可能出现的缺血性改变、动脉闭塞及其他并发症。尽管在33名患者(22%)中发现了动脉闭塞的迹象,但没有患者抱怨或出现缺血性损伤的体征。插管时间超过6小时后出现这些体征的情况(43%)明显比插管时间少于6小时后(17%)更为常见。在动脉闭塞恢复过程中,所有患者的动脉上均可触及搏动,即使血流似乎已消失。到随访结束时,33条闭塞动脉中有19条恢复了血流。
