A 53-year-old woman was referred for ventricular fibrillation with resuscitation. A CT-angiography showed signs of a right ventricular enlargement without obvious cause. A cardiac MRI demonstrated a dilated and hypokinetic right ventricle with extensive late gadolinium enhancement. Arrhythmogenic right ventricular dysplasia (ARVD) was suspected according to the "revised ARVD task force criteria". An endomyocardial biopsy was inconclusive. The patient developed purulent pericarditis after epicardial ablation therapy and died of toxic shock syndrome. The post-mortem pathologic examination demonstrated sarcoidosis involving the heart, lungs, and thyroid gland.

This case report shows the full spectrum evolution of type B intramural hematoma under conservative treatment, with initial progression into a true aortic dissection, followed by extremely rare near-complete healing of the dissection at followup.

Experiencia preliminar en el tratamiento combinado de metástasis vertebrales mediante radiofrecuencia y cifoplastia en sesión única G. Buitrago, E. Castro, J. C. Garrido, P. Fernández-García, J. ABSTRACTObjectives: Describe our preliminary experience in the treatment of vertebral metastases by radiofrequency and Kyphoplasty combined in one single session.Material and methods: Four patients with histologically confirmed single spinal metastasis (breast, prostate, lung and myeloma in L1, L5, D12, D12, respectively) were treated. The indication in all cases was pain with a poor response to medical treatment. All patients had pain in the range 6-7 visual analogue scale (VAS). In two cases there was a lytic lesion of the spinal posterior wall. After obtaining informed consent, and under sedation and local anesthetic the procedure took place. The transpedicular approach took place with a 11 G bone puncture system. Two radiofrequency needles were coaxially inserted to carry out an ablation cycle through each pedicle. During the ablation cycle the tip of the ablation neddle stood between the anterior and middle third of the vertebral body, while the second needle was used as thermal sensor with its end to the height of the vertebral posterior wall. The duration of each cycle of ablation was 8 minutes reaching intratumoral temperatures of 70-80 °C. Transpedicular Kyphoplasty was performed subsequently.Results: No complications were reported during or after the procedure and patients were discharged in the first 24 hours. There was an immediate improvement in pain after the procedure (with a VAS 1-2 intensity pain) in all patients. During follow up, analgesic medication was withdrawn in three patients, and there was no evidence of disease progression or recurrence of pain (pain intensity 1 (VAS) in a follow-up in the range of 8-14 months). Clinical and radiological follow-up after discharge could not be performed on a patient.Conclusion: The use of radio-frequency associated with Kyphoplasty in vertebral metastatic disease can contribute to the management of refractory pain to medical treatment.Key words: Vertebral metastases. Radiofrequency. Kyphoplasty. RESUMENObjetivos: Describir nuestra experiencia preliminar en el tratamiento de metástasis vertebrales mediante radiofrecuencia y cifoplastia combinadas en sesión única.Material y métodos: Se trataron cuatro pacientes con metástasis vertebral única confirmada histológicamente (mama, próstata, pulmón y mieloma en D12, L1, L5 y D12, respectivamente). La indicación en todos los casos fue el dolor con una mala respuesta al tratamiento médico habitual. Todos los pacientes presentaban dolor en el rango 6-7 de la escala visual analógica (EVA). En dos casos existía lesión lítica del muro posterior. Tras la obtención del consentimiento informado se realizó el procedimiento bajo sedación e infiltración anestésica local. Se efectuó abordaje transpedicular bilateral con sistemas de punción ósea 11G. Se insertaron de forma coaxial dos agujas de radiofrecuencia para efectuar un ciclo...
