The clinical utility of the Ga-67 scan has been studied in 9 patients with clinical suspicion of vascular graft infection. Eleven grafts were analyzed: 4 aortobifemoral, 2 iliofemoral, 3 femoropopliteal, 1 axillofemoral, and 1 axillobifemoral. The Ga-67 scan was positive in 8 grafts with bacteriological proof of infection and negative in 3 grafts in which infection was ruled out by clinical follow-up. A Ga-67 scan also demonstrated the spread of infection to the thigh in two patients and to the pelvis in another two patients. In 4 patients CT was performed. The CT findings included graft thrombosis, perigraft fluid collection and thickened graft wall. No discrepancies were found between the CT scan and Ga-67 scan. In three patients a control Ga-67 scan was carried out after specific antibiotic and surgical treatment. Two of these showed increased Ga-67 uptake and spreading of infection along the graft; in the other patient, a Ga-67 scan revealed normalization after resolution of an abdominal abscess. In conclusion, the Ga-67 scan proved useful in the diagnosis of vascular graft infection, the definition of location of the extent of the disease and in the evaluation of the efficiency of treatment.
对9例临床怀疑血管移植物感染的患者进行了镓-67扫描的临床效用研究。分析了11个移植物：4个主动脉双股移植物、2个髂股移植物、3个股腘移植物、1个腋股移植物和1个腋双股移植物。镓-67扫描在8个有细菌学感染证据的移植物中呈阳性，在3个经临床随访排除感染的移植物中呈阴性。镓-67扫描还显示，两名患者的感染扩散至大腿，另外两名患者的感染扩散至骨盆。4例患者进行了CT检查。CT表现包括移植物血栓形成、移植物周围积液和移植物壁增厚。CT扫描和镓-67扫描之间未发现差异。3例患者在接受特异性抗生素和手术治疗后进行了对照镓-67扫描。其中2例显示镓-67摄取增加且感染沿移植物扩散；另一例患者，腹部脓肿消退后镓-67扫描显示正常化。总之，镓-67扫描在血管移植物感染的诊断、疾病范围位置的界定以及治疗效果评估方面被证明是有用的。
