To determine the clinical accuracy of combined CT venography (CTV) and spiral CT angiography (SCTA) in patients suspicious of acute pulmonary thrombo-embolism.
278 consecutive patients referred for SCTA for suspicion of acute pulmonary embolism (APE) underwent subsequent evaluation of the veins of the lower limbs and abdomen (CTV) within one examination without additional injection of contrast medium. Sixty-nine patients had no further study. Two hundred and nine patients were included in the study, 199 had US and 51 phlebography (PG) within 48 hours from SCTA-CTV. The investigators were blinded to the results of CT. When results of CTV and US were discordant, phlebography was indicated.
SCTA was positive in 89 patients, negative in 119 and indeterminate in 1. CTV was positive in 99 patients, negative in 103 and indeterminate in 7. US was positive in 87 patients, negative in 97 and indeterminate in 15. PG was positive in 21 patients, negative in 29 and indeterminate in 1. Excellent correlation was found between CTV and US (k = 0.84) and moderate correlation between CTV and PG, and US and PG (k = 0.53).
Combined SCTA and CTV is a rapid and accurate one-session examination in patients suspicious of acute pulmonary thrombo-embolism.
确定联合CT静脉造影（CTV）和螺旋CT血管造影（SCTA）对疑似急性肺血栓栓塞患者的临床诊断准确性。
278例因疑似急性肺栓塞（APE）而接受SCTA检查的连续患者，在一次检查中后续对下肢和腹部静脉进行了评估（CTV），无需额外注射造影剂。69例患者未进一步检查。209例患者纳入研究，其中199例在SCTA-CTV检查后48小时内接受了超声检查（US），51例接受了静脉造影（PG）。研究人员对CT结果不知情。当CTV和US结果不一致时，则进行静脉造影检查。
SCTA检查结果为阳性的有89例，阴性的有119例，不确定的有1例。CTV检查结果为阳性的有99例，阴性的有103例，不确定的有7例。US检查结果为阳性的有87例，阴性的有97例，不确定的有15例。PG检查结果为阳性的有21例，阴性的有29例，不确定的有1例。发现CTV与US之间具有良好的相关性（k = 0.84），CTV与PG、US与PG之间具有中等相关性（k = 0.53）。
对于疑似急性肺血栓栓塞的患者，联合SCTA和CTV检查是一种快速且准确的一站式检查方法。
