Angiojet Thrombo-aspiration Guided by Trans-Oesophageal Ultrasound.

ABSTRACT: INTRODUCTION:A 59 year old woman presented with acute right leg ischemia. On the computed tomography scan, thrombi were seen in the brachiocephalic trunk, in the descending aorta, in the infrarenal aorta, in the right deep femoral artery, and in the right crural arteries. TECHNIQUE:To remove the risk of cerebral emboli, thrombo-aspiration of the brachiocephalic trunk was planned, with associated thrombectomy of the infrarenal aorta, the right deep femoral artery, and the right crural arteries. Because the brachiocephalic thrombus could not be visualized with angiography, the anesthetists, who were performing a trans-oesophageal ultrasound of the heart, were asked to locate the thrombus, which was easily seen on the trans-oesophageal ultrasound. The aspiration catheter Angiojet (Boston Scientific, Marlborough, MA, USA) could be positioned under ultrasound guidance. Complete aspiration of the thrombus was then confirmed with the ultrasound (see video). The thrombectomy of the infrarenal aorta and right leg was then performed by open surgery. The patient's recovery was uneventful. Despite extensive investigations no etiology was found for the thrombi. DISCUSSION:Pre-operative trans-oesophageal ultrasound is routinely performed by anesthetists in patients with acute ischemia, to search for a cardiac source of emboli. In this case it had the added advantage of helping to locate and aspirate a thrombus in the brachiocephalic trunk.

Project description:Aim:The aim of this study was to compare the diagnostic adequacy of computed tomography (CT)-ultrasound (US) fusion image-guided fine needle aspiration (FNA) and US-guided FNA in patients with suspected hepatic metastases. Methods:Thirty consecutive patients of either sex with known or unknown primary malignancy suspected of having liver metastases on both US and CT, whose multiphasic contrast-enhanced computed tomography was performed using a 64-slice or a higher slice CT scanner, and who were referred for percutaneous FNA were included in this prospective study approved by the institutional review board of the study institute. CT-ultrasound fusion image-guided FNA of the largest lesion using electromagnetic tracking and with freehand ultrasound-guided FNA were performed in the same sitting. Value of fitness, which is a rough estimate of how well the fusion has been achieved, was recorded. Diagnostic adequacy of smears was assessed by a scoring system based on cellular material, background blood/clot, degree of cellular degeneration or trauma, and retention of architecture. Results:The size of the lesions ranged from 1 to 10 cm, and the depth of location of the lesions ranged from 1.4 to 9.3 cm. The fusion fitness values ranged from 1.2 to 10 mm. The scores of the smears did not correlate with lesion size, depth of location, and fusion fitness value. Diagnostic adequacy was seen in 90% and 93.3% of lesions sampled by fusion image guidance and ultrasound guidance, respectively (p = 0.655). All the lesions that yielded inadequate smears by fusion guidance were deep-seated lesions (>5 cm). All the lesions that yielded inadequate smears by ultrasound guidance were small lesions (<3 cm). No complications were encountered in any of the patients. Conclusion:Fusion image-guided FNA is a safe procedure with a high diagnostic adequacy rate. Fusion image-guided FNA is not better than US-guided FNA for conspicuous hepatic lesions; however, it may be useful in inconspicuous lesions.
