Zusammenfassung: | A hospital based prospective study was conducted from July 2001 to July 2015 at the Department of Radiology, Jordan University Hospital, Amman, Jordan. During that period, five cases of double inferior vena cava (DIVC) were discovered among a cohort of 7722 patients (3861 men and 3861 women, 49.5 [+ or -] 16.9 years, range 16-78 years). Cases were diagnosed by contrast-enhanced Spiral CT venography (CTV) and confirmed by turbo three-dimensional (3D) time- of-flight contrast-enhanced MR venography. The majority of patients 3166 (41 %) were referred for staging and follow-up of malignancy, postoperative complications 1777 (23 %), nonspecific abdominal pain 1467 (19 %), preoperative assessment 849 (11 %) and trauma 463 (6 %). Magnetic resonance venography showed higher sensitivity, diagnostic accuracy and noninvasive modality for assessment of IVC map. MRV is a more useful, noninvasive modality for assessment of IVC map. DIVC is a common anomaly, its incidence in our study found to be 0.064 %. The incidence, literature review, embryogenesis, and importance of this anomaly are discussed. In addition, sample figures of relevant cases are provided. KEY WORDS: Magnetic resonance angiogram; Inferior vena cava; Congenital anomalies. En el Departamento de Radiologia del Hospital de la Universidad de Jordania, Amman, Jordania, se llevo a cabo un estudio prospectivo entre el mes de julio de 2001 al mes de julio del 2015. Durante ese periodo se descubrieron cinco casos de vena cava inferior doble (VCID) en una cohorte de 7722 pacientes (3861 hombres y mujeres 3861, de 49,5 [+ or -] 16,9 anos, con un rango de edad de 16-78 anos). Los casos fueron diagnosticados por medio de venografia por tomografia computada espiral con contraste (TCV) y confirmados por medio de venografia por estudio tridimensional turbo. La mayoria de los pacientes (3166, 41 %) fueron remitidos para estadificacion y seguimiento de tumores malignos. Se presentaron complicaciones postoperatorias en 1777 pacientes (23 %), dolor abdominal no especificado en 1467 (19 %), evaluacion preoperatoria en 849 (11 %) y traumatismo en 463 pacientes (6 %). La venografia por resonancia magnetica (RMV) mostro una mayor sensibilidad, precision diagnostica, y resultando no invasiva para la evaluacion de la vena cava inferior (VCI). RMV es una modalidad mas util, no invasiva para la evaluacion de la VCI. VCID es una anomalia frecuente, encontrandose en nuestro estudio una incidencia de 0,064 %. Ademas se realizo una rev |
