Title: Intra-arterial Ultra-low-Dose CT Angiography of Lower Extremity in Diabetic Patients

Abstract

PurposeTo image lower extremity arteries by CT angiography using a very low-dose intra-arterial contrast medium in patients with high risk of developing contrast-induced nephropathy (CIN).Materials and MethodsThree cases with long-standing diabetes mellitus and signs of lower extremity atherosclerotic disease were evaluated by CT angiography using 0.1 ml/kg of the body weight of contrast medium given via 10-cm-long 4F introducer by puncturing the CFA. Images were evaluated by an interventional radiologist and a cardiovascular surgeon. Density values of the lower extremity arteries were also calculated. Findings in two cases were compared with digital subtraction angiography images performed for percutaneous revascularization. Blood creatinine levels were followed for possible CIN.ResultsIntra-arterial CT angiography images were considered diagnostic in all patients and optimal in one patient. No patient developed CIN after intra-arterial CT angiography, while one patient developed CIN after percutaneous intervention.ConclusionIntra-arterial CT angiography of lower extremity might be performed in selected patients with high risk of developing CIN. Our limited experience suggests that as low as of 0.1 ml/kg of the body weight of contrast medium may result in adequate diagnostic imaging.

  • We report our experience with the use of intra-arterial chemotherapy and embolization before limb salvage surgery in patients with osteosarcoma of the lower extremity. We evaluated the effect of this procedure on the degree of tumor necrosis and on the amount of blood loss during surgery. We reviewed the medical records of all patients who received intra-arterial chemotherapy and embolization before undergoing limb salvage surgery for osteosarcoma of the lower extremity at our institution between January 2003 and April 2008. Patient demographic, tumor characteristics, treatment details, postembolization complications, and surgical and pathological findings were recorded for each patient. We evaluatedmore » the operative time, estimated blood loss (EBL), and volume of blood transfusion during surgery and in the postoperative period in all patients in the study group. The same parameters were recorded for 65 other patients with lower extremity osteosarcoma who underwent limb salvage operation at our institution without undergoing preoperative intervention. The study included 47 patients (25 males and 22 females). Angiography showed that the tumors were hypervascular. Intra-arterial chemotherapy and embolization were performed successfully, resulting in a substantial reduction or complete disappearance of tumor stain in all patients. No major complications were encountered. At the time of surgery, performed 3-7 days after embolization, a fibrous edematous band around the tumor was observed in 43 of the 47 patients, facilitating surgery. The goal of limb salvage was achieved successfully in all cases. Percentage tumor necrosis induced by treatment ranged from 70.2% to 94.2% (average, 82.9%). EBL during surgery, EBL from drains in the postoperative period, total EBL, and transfusion volumes were significantly lower in the 47 study patients compared to the 65 patients who underwent surgery without preoperative treatment with intra-arterial chemotherapy and embolization. The mean operative time was also significantly less in the intervention group compared to the nonintervention group (73.2 vs. 88.5 min; p < 0.05). In conclusion, intra-arterial chemotherapy and embolization performed 3 to 7 days before limb salvage surgery in patients with lower extremity osteosarcomas can cause substantial tumor necrosis, reduce the EBL and transfusion requirements during surgery, and induce formation of a false capsule around the tumor, thus facilitating surgical excision of the tumors.« less
  • Purpose: To exploit the potential benefits of percutaneous transluminal angioplasty (PTA) in patients with short obstructive lesions in the lower extremity, it is preferable to select patients suitable for PTA before proceeding to hospital admission and angiography. The aim of this prospective study was to evaluate the role of color-coded duplex scanning in the correct selection of patients for PTA and its influence on planning the approach to the lesion. Methods: On the basis of clinical history, physical examination, pressure indices, and ultrasound duplex scanning, 109 patients were scheduled for PTA. Results: The indication for PTA was correct in 103more » patients (94%), while the procedure was performed successfully in 98 patients (90%). The approach to the lesion was planned successfully in the majority of patients. Conclusion: This study shows that it is justifiable to plan PTA on the basis of information obtained by duplex scanning. Results of the duplex scan may guide the catheterization route.« less
  • As part of an ongoing study comparing digital subtraction angiography (DSA) with conventional film-screen angiography, 150 patients were examined with arterial contrast material injections and digital filming techniques alone or combined with conventional angiography. Of 247 injections, the DSA study was good or excellent in 236, approaching the quality of conventional angiography for visualization of vessels greater than 1 mm in size. Advantages included improved vascular detail in selected areas such as the skull base, visualization of minimal contrast concentration in diseased vessels or postoperatively, and imaging of vessels distal to stenoses without the hazards of selective catheterization. DSA permittedmore » rapid positioning under fluoroscopic control, instantaneous viewing of subtracted images, and reduced technologist time and film costs. Contrast material volume was reduced by 40 to 60%, allowing multiple studies in one sitting and study of patients with renal compromise.« less
  • Purpose: To assess the role of multislice computed tomography angiography (MCTA) in the evaluation of renal artery stents, using intra-arterial digital subtraction angiography (DSA) as the gold standard. Methods: Twenty consecutive patients (15 men, 5 women) with 23 renal artery stents prospectively underwent both MCTA and DSA. Axial images, multiplanar reconstructions and maximum intensity projection images were used for diagnosis. The MCTA and DSA images were each interpreted without reference to the result of the other investigation. Results:The three cases of restenosis on DSA were detected correctly by MCTA; in 19 cases where MCTA showed a fully patent stent, themore » DSA was also negative. Sensitivity and negative predictive value (NPV) of MCTA were therefore 100%. In four cases, MCTA showed apparently minimal disease which was not shown on DSA. These cases are taken as false positive giving a specificity of 80% and a positive predictive value of 43%. Conclusion: The high sensitivity and NPV suggest MCTA may be useful as a noninvasive screen for renal artery stentrestenosis. MCTA detected mild disease in a few patients which was not confirmed on angiography.« less
  • Induction of therapeutic angiogenesis by autologous bone marrow mononuclear cell transplantation has been identified as a potential new option in patients with advanced lower-limb ischemia. There is little evidence of the benefit of intra-arterial cell application in upper-limb critical ischemia. We describe a patient with upper-extremity critical limb ischemia with digital gangrene resulting from hypothenar hammer syndrome successfully treated by intra-arterial autologous bone marrow mononuclear cell transplantation.
