“…19 However thoroughly abdominal cleaning is carried out, the vascular graft is not close to the liver or spleen, and surgical incision uptake tends to decrease after the first week. 3,14 CT utility for graft infection has also been demonstrated previously. 3,7,20 CT is also able to detect other complications of vascular surgery such as retroperitoneal haematomas, aortoduodenal fistula, pseudoaneurism, vascular thrombosis, intestinal infarction, and postsurgical pancreatitis.…”

“…14,15 Although the Ga-67 scan has demonstrated a sensitivity of 78-100% and a specificity greater than 90% for graft infection, 3,15 it has excited little interest and received only limited attention from a few researchers. 6,16,17 In 1980, Causey et a1.…”

“…From these results, the authors recommend the CT as the initial choice for exploration, leaving the Ga-67 scan to those cases where the results of the CT scan are not conclusive. 3 In conclusion, vascular graft infection as a complication of vascular surgery is difficult to diagnose and may have dramatic consequences in terms of morbidity and mortality rates, and the need to carry out limb amputation. Several medical explorations are required to confirm its presence and extent.…”

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.

“…Compared with Indium-111 labelled WBC scan, Gallium-67 citrate scintigraphy is the preferred method because it is less expensive and does not require special preparation. According to previous reports [3][4][5][6], Gallium-67 citrate scintigraphy is a good tool to diagnose graft infection, with a sensitivity of 78-100% and a specificity of nearly 100%. The only obstacle to Gallium-67 citrate scintigraphy is the incision uptake of graft, which rapidly decreases after the first week of operation [3,4].…”
