Digitale Bilddiagn. 1989 Mar;9(1):42-7.
33 CT-studies of 26 patients with alloplastic vascular prostheses were evaluated and compared with postoperative digital subtraction-angiography in 16 cases. 13 patients had no pathologic findings confirmed by further clinical development. In 4 cases bypass infection was diagnosed, which CT findings were perigraft gas (2/4), perigraft fluid (4/4), cm-enhancement (4/4) and fistulas (2/4). 10-21 d. post.-op. sterile hematomas were found in 3 patients. Further 3 cases had 5 weeks-2 post.-op. perigraft seromas. CT was method of first choice for diagnostic of perivascular alterations after bypass surgery. DSA was complementary to CT and should be performed to detect vascular complications.
对26例使用异体血管移植物患者的33项CT研究进行了评估,并与16例患者术后数字减影血管造影结果进行了比较。13例患者经进一步临床发展证实无病理发现。4例诊断为旁路感染,CT表现为移植物周围气体(2/4)、移植物周围液体(4/4)、增强扫描(4/4)和瘘管形成(2/4)。术后10 - 21天,3例患者发现无菌性血肿。另外3例患者术后5周 - 2个月出现移植物周围血清肿。CT是旁路手术后血管周围改变诊断的首选方法。DSA是CT的补充检查,用于检测血管并发症时应进行该项检查。
