RESUMO

BACKGROUND AND PURPOSE: The thyrocervical trunk (TCT) is the second ascending branch of the subclavian artery. It is considered a 'border territory' between interventional vascular radiology and interventional neuroradiology because it gives rise to branches both cervical and to the upper limbs. We describe the TCT branches anatomy, the most frequent variants, and expose eight endovascular procedures performed through the thyrocervical trunk. METHODS: A retrospective review of all the interventional radiology procedures carried out through the TCT in our tertiary care center from August 2014 to January 2017 is presented. RESULTS: A total of eight endovascular procedures through the TCT including six preoperative embolizations: three paragangliomas, a cervical vertebral metastasis, a cervical vertebral aneurysmal bone cyst, and a very rare case of nerve root extradural cervical hemangioblastoma, as well as two emergency embolizations: a patient with a cervical traumatic active bleeding hematoma and a recurrent hemoptysis in a single ventricle patient. CONCLUSIONS: A correct knowledge of the vascular anatomy, anatomical variants, and anastomosis (especially with the anterior spinal artery) of the TCT is essential for a safe embolization, both preoperatively and on an emergency basis. In cases of recurrent hemoptysis and severe lower-neck injuries, the TCT should always be reviewed.

RESUMO

OBJECTIVE: Review of the experience of a tertiary care centre for almost 10 years in the CT diagnosis of non-occlusive mesenteric ischaemia (NOMI). Analysis of CT findings, correlation with clinical outcomes and evaluation of the usefulness of measuring the superior mesenteric artery (SMA) diameter for the diagnosis of NOMI. METHODS: 106 patients were diagnosed with NOMI in a biphasic CT examination from 2008 to 2017 in our hospital. Clinical outcomes and CT findings were reviewed. In 55 patients, the diameter of the SMA was compared with a previous CT scan where NOMI was not the diagnosis, and statistical analysis using paired t-test was performed. RESULTS: 81 patients (76%) had findings consistent with small bowel ischaemia and the ileum was the segment most commonly involved (47%). Lack of wall enhancement, pneumoperitoneum, pneumatosis intestinalis and portal venous gas were all considered signs of bowel necrosis and surgery was performed promptly. 70 patients had signs of vascular narrowing of the SMA branches and in the 55 cases with a previous CT scan, there were statistically significant differences regarding the SMA diameter with a mean reduction of the artery calibre and standard deviation of 1.93 ± 1.1 mm between the NOMI and non-NOMI scans (p < 0.001). CONCLUSION: Acknowledgment of characteristic bowel necrosis CT findings is crucial for determining the therapeutic attitude and the use of previous CT scans to compare the SMA diameter may help the radiologist to achieve an early diagnosis of NOMI in an often critically ill patient population. Advances in knowledge: Diagnosis of NOMI can be difficult in cases of partial mural ischaemia, thus objective data (diameter of the SMA) should be useful for the radiologist to include NOMI as the first diagnostic option in the differential diagnosis.

RESUMO

OBJETIVO: Se realiza un repaso de la litotricia renal percutánea comenzando con una pequeña introducción histórica, revisando la evolución de la técnica desde sus comienzos. MÉTODOS: En el apartado de indicaciones de la NLP analizamos, empezando por las grandes masas litiásicas, todas las indicaciones que hemos ido encontrando en los últimos 15 años de desarrollo de la técnica y su vigencia actual. Exponemos la metodología actual de la NLP en nuestra Unidad de Litotricia, haciendo un recorrido paso a paso de la técnica tal como nosotros la realizamos. Comentamos detalles técnicos, aparataje, trucos y complicaciones, así como sus posibles soluciones. RESULTADOS Y CONCLUSIONES: La NLP sigue siendo en nuestra opinión la técnica de elección para la mayoría de las litiasis que superen los 2 cm. Consideramos fundamental el aprendizaje de todas las técnicas endourológicas por las nuevas generaciones de urólogos ya que el desarrollo tecnológico actual nos permite actual en todos los puntos de la vía urinaria por métodos endoscópicos (AU)

RESUMO

OBJETIVO: Valorar y revisar en nuestra serie la incidencia de los diferentes tipos de hipospadias, así como el porcentaje de complicaciones sufridas mediante el empleo de diferentes técnicas y materiales. MÉTODOS: 130 pacientes afectos de hipospadias e intervenidos quirúrgicamente durante los últimos 6 años. Sección de Urología Pediátrica. RESULTADOS: H. Glandares (13). H. BalanoPrepuciales (56). H. Peneano Distales (42). H. Peneano Medios (9). H. Peneano Proximales (2). H. Penoescrotales (8).Con respecto a las técnicas empleadas: Meatotomía Mickulitz (6). MAGPI (24). Mathieu (77). Crawford (5). Onlay (7). Duckett (3). Retik (4). Duplay (1). Denis-Brown (2). Transposición penoescrotal (1). Con respecto a las principales complicaciones: Fístulas (20). Hematomas (4). Estenosis Meato Uretral (4). Infección (3). Megauretra (3). Necrosis Cutánea (1). CONCLUSIONES: Realizamos la intervención aproximadamente hacia los 18 meses de edad, teniendo un porcentaje de complicaciones, en cuanto a fistulización cercano al 15 por ciento, comparable al de otras series de la literatura, aunque desde que utilizamos material reabsorbible monofilamento, el número de fistulizaciones se ha visto reducido notablemente, del 20 por ciento acerca del 5 por ciento, y aunque influyen otros factores, creemos que la menor reacción de cuerpo extraño sobre el tejido es responsable en gran medida de este descenso (AU)
