Manejo conservador de las lesiones esplénicas: experiencia en 136 pacientes con traumatismo esplénico cerrado / Conservative management of splenic lesions: experience in 136 patients with blunt splenic injury

Objetivo. Evaluar la eficacia de las pruebas de imagen en la selección del manejo terapéutico de los pacientes. Relacionar el grado de lesión esplénica con el tratamiento instaurado. Exponer los beneficios de la embolización en el trauma esplénico. Material y métodos. Se han estudiado retrospectivamente un total de 136 lesiones esplénicas. Se analizaron los principales mecanismos lesionales, los hallazgos de imagen obtenidos mediante ecografía FAST y TC, el espectro lesional, el manejo terapéutico y la evolución. Resultados. La edad media fue 34,81 años y el principal mecanismo lesional los accidentes de tráfico. El 39,70% de los casos (54 pacientes) mostraban signos de inestabilidad hemodinámica, y el 60,30% restante (82 pacientes) estaban estables o respondían a maniobras de resucitación. La ecografía FAST fue la técnica de imagen inicial y más utilizada en los pacientes inestables, mientras que la TC fue la técnica más empleada en los pacientes estables. El tratamiento fue quirúrgico en el 79,99% de las lesiones de alto grado y conservador expectante en el 55,69% de las lesiones de bajo grado. El 8,54% de los pacientes estables se manejó con arteriografía y embolización. Conclusión. La ecografía FAST demostró ser una técnica decisiva en la elección del tratamiento quirúrgico en los enfermos inestables. Las lesiones de alto grado se asociaron con mayor frecuencia a un tratamiento quirúrgico y las de bajo grado a un manejo no quirúrgico. La arteriografía con embolización demostró ser una terapia eficaz en el tratamiento de lesiones vasculares en enfermos estables (AU)

Objective. To evaluate the usefulness of imaging tests in selecting the treatment for patients with blunt splenic trauma. To relate the grade of splenic lesion with the treatment. To describe the benefits of embolization in splenic trauma. Material and methods. We retrospectively studied 136 splenic lesions. We analyzed the main mechanisms of injury, the imaging findings at focused assessment with sonography for trauma (FAST US) and CT, the spectrum of lesions, the therapeutic management, and the outcome. Results. The mean age of patients was 34.81 years and the most common mechanism of injury was traffic accidents. Signs of hemodynamic instability were observed in 54 (39.70%) patients; the remaining 82 (60.30%) patients remained stable or responded to resuscitation. FAST US was the initial imaging technique and the most commonly used technique in unstable patients, whereas CT was the most commonly used technique in stable patients. Surgical treatment was used in 79.99% of the high grade lesions and conservative treatment was used in 55.69% of the low grade lesions. Angiography and embolization were used to manage 8.54% of the stable patients. Conclusion. FAST US is decisive in choosing the surgical treatment in unstable patients. High grade lesions are associated with a higher frequency of surgery and lower grade lesions are associated with a higher frequency of nonsurgical management. Angiography with embolization is efficacious in the treatment of vascular lesions in stable patients (AU)

[Tumor thrombosis of the left renal vein and inferior vena cava secondary to renal cell carcinoma. Findings with ultrasonography, Echo-Doppler, and computerized tomography]. / Trombosis tumoral de la vena renal izquierda y vena cava inferior secundaria a carcinoma de células renales. Hallazgos en ecografía, ECO-doppler y tomografía computerizada.

Renal cell carcinoma represents a 2.5-3% of all neoplastic processes, usually seen un patients older than 50 years. 60-75% are resectable at diagnosis, representing local or metastatic advanced disease the rest of them. This tumor tends to spread intravascularly, leading to tumoral thrombosis within the inferior caval vein (ICV) and renal vein 4-10% and 21-35% of cases, respectively. As the only effective treatment is surgical resection, preoperative determining of the thrombus extension is crucial. Thus, an accurate radiological study including ultrasound, doppler sonography, computed tomography and/or Magnetic Resonance, is key for these patients. We present a 49 year-old patient with renal cell carcinoma and associated tumoral thrombosis in inferior caval vein and left renal vein; we provide the most significant figures, explaining its most characteristic radiological findings.

Hallazgos en ecografía, eco-doppler y tomografía computerizada / Tumoral thrombosis in both left renal vein and lower cava vein secondary to renal cell carcinoma. Ultrasonography, eco-doppler and computerized tomography findings

El carcinoma de células renales representa un 2,5-3 por ciento de todos los cánceres, siendo más frecuente en pacientes mayores de 50 años. De ellos, el 60-75 por ciento son resecables al momento del diagnóstico, presentando el resto de los casos enfermedad avanzada local o metastásica. Este tumor tiende a extenderse intravascularmente, produciendo trombosis tumoral en la vena cava inferior y vena renal en un 4-10 por ciento y 2135 por ciento de los casos, respectivamente. Dado que el único tratamiento efectivo es la resección quirúrgica, resulta prioritario determinar la extensión de la trombosis tumoral previamente a la cirugía. Por tanto, en estos pacientes es fundamental un cuidadoso estudio radiológico que incluya, al menos, ecografía, eco-doppler, TC y/o RM abdominal. Presentamos el caso de un paciente de 49 años con carcinoma renal y trombosis tumoral secundaria de la vena renal izquierda y de la VCI, aportando las imágenes más significativas y comentando sus principales hallazgos radiológicos (AU)
