Literature case study paclitaxel popliteal pseudoaneurysm.It was reported that the patient developed pseudoaneurysm post treatment with this device, requiring an additional device.This 4.0 x 60mm ranger paclitaxel-coated pta balloon catheter was selected for use in an endovascular therapy (evt) procedure to treat a right popliteal artery occlusion.During the index procedure, a 6-fr sheath was inserted into the right common femoral artery via the ipsilateral approach.Control angiography revealed an occlusion of the distal aspect of the popliteal artery.In addition, a linear contrast agent leakage was observed.A distal puncture was subsequently performed, and the occlusion was crossed via a retrograde approach with a 0.014 inch guidewire.After five minutes of inflation with 2.5mm balloon, the contrast agent leakage disappeared.Although subintimal wiring was detected by intravascular ultrasound (ivus), the wires could not cross the true lumen in the middle part of the lesion.Stent placement was not performed because of the lesion location, vessel size, and the reasonable angiographic result after the balloon angioplasty.The vessel diameter of the lesion was measured to be approximately 4mm by ivus, and additional dilation with this 4.0 x 60mm ranger paclitaxel-coated pta balloon catheter was performed.The final angiography revealed vessel dilation without contrast agent leakage.After evt, the residual pain disappeared.Three months post procedure, the patient presented with right knee pain and was subsequently hospitalized.Computed tomography was performed which revealed a right popliteal pseudoaneurysm.An evt procedure was therefore performed and ivus revealed a vessel wall defect at the site of the pseudoaneurysm.A stent graft was implanted, and post-balloon dilation was performed.Final angiography of the second evt revealed exclusion of the popliteal pseudoaneurysm.After stent graft implantation, the pain in the right knee improved.
