چکیده
OBJECTIVE To analyze the results of ten angioplasties of TASC C and D femoropopliteal lesions using CO2 as primary contrast in patients with no formal contraindication to iodine, aiming to decrease allergic reactions and potential nephrotoxicity in high-risk patients. METHODS We describe the results of ten angioplasties of TASC C and D femoropopliteal lesions using CO2 as primary contrast in patients with high risk for open revascularization and no formal contraindication to iodine. We analyzed feasibility of the procedures, complications, quality of the angiographic images, clinical and surgical outcomes, and costs of C and D lesions treated using CO2 as contrast medium. RESULTS The use of CO2 in C and D lesions needed iodine complementation in most of the cases (nine cases) but decreased the potential nephrotoxicity of iodine contrast medium by the reduction of its volume in this group of high-risk patients. The extension of the arterial lesions was the factor that most contributed to the need for iodine supplementation due to the difficulty to visualize the refill after a long arterial occlusion. CONCLUSION The use of CO2 as contrast in patients with C and D lesions with no restriction for iodine contrast medium was an alternative that did not dismiss the need of iodine supplementation in most of the cases, but could decrease the potential nephrotoxicity of iodine constrast medium. OBJETIVO Analisar os resultados de dez angioplastias de lesões fêmoro-poplíteas TASC C e D utilizando CO2 como meio de contraste primário em pacientes sem restrição ao meio de contraste iodado com o objetivo de diminuir reações alérgicas e potencial de nefrotoxicidade em pacientes de alto risco. MÉTODOS Descrevemos os resultados de dez angioplastias de lesões fêmoro-poplíteas TASC C e D utilizando CO2 como meio de contraste primário em pacientes de alto risco para revascularização aberta e sem contraindicação formal a iodo. Analisamos possibilidade de execução dos procedimentos, complicações, qualidade das imagens obtidas, desfechos clínicos e cirúrgicos e custos das lesões C e D tratadas com CO2 como meio de contraste. RESULTADOS O uso de CO2 nas lesões C e D necessitou de complementação de iodo na maioria dos casos (nove casos), porém reduziu o potencial de nefrotoxicidade do meio de contraste iodado, diminuindo seu volume nesse grupo de pacientes de alto risco. A extensão das lesões arteriais foi o fator que mais contribuiu para necessidade de suplementação de iodo, devido à dificuldade de visualizar o reenchimento após oclusão arterial longa. CONCLUSÃO O uso de CO2 como contraste em pacientes com lesões C e D sem restrição ao meio de contraste iodado foi uma alternativa que não excluiu a necessidade de suplementação com iodo na maioria dos casos, porém pôde diminuir o potencial de nefrotoxicidade do meio de contraste iodado.

BACKGROUND Open surgery is the preferred approach for the treatment of type D lesions according to the Trans-Atlantic Inter-Society Consensus (TASC) II guideline, but endovascular solutions also appear to be a valid option in selected patients. The study aimed to identify the risk factors of restenosis after open and endovascular reconstruction of symptomatic TASC II D aortoiliac occlusive lesi...

BACKGROUND Iodine contrast medium (ICM) is considered gold standard in endovascular revascularization procedures. However, nephrotoxicity and hypersensitivity to ICM are causes that limit its indiscriminate use. Carbon dioxide (CO2) contrast angiography has been used as an alternative in patients with formal contraindication to ICM. However, no studies to the present date have compared in a ran...
