To review facial fractures and their medical and surgical outcomes. 2. To discuss relevant imaging findings of facial for correct management. 3. To evaluate the Le Fort classification. CONTENT ORGANIZATION 1. Trauma mechanism of facial fractures. 2. CT Appearance of facial fractures. a. MDCT 64-channels. 3. Sample cases of Emergency Hospital. 4. Evaluation of post-operative cases. SUMMARY The major teaching points of this exhibit are: 1. MDCT 64-channel can provide accurate diagnosis through imaging and help surgical management to prevent severe functional disability and cosmetic deformity. 2. Emphasize the common fracture patterns and the surgical relevance in order to aid the communication between radiologists and surgeons to improve the management of facial fractures.

CONTENT ORGANIZATION - Causes os traumatic and non-traumatic hemoperitoneum; - Sites and pathways of hemoperitoneum; - Pathogenesis, clinical features, radiologic findings associated; - Imaging and pathological changes in different etiologies of hemoperitoneum and its appearances. - Possible conducts, surgical or clinical, related to its causes. SUMMARY The major teaching points of this exhibit are: 1. Possible causes of hemoperitoneum; 2. Hemoperitoneum signs, with possible pathogenesis, clinical features, radiologic findings associated. 3. Imaging / pathology changes in different etiologies of hemoperitoneum. 4. Possible conducts, surgical or clinical, aided by radiologist to its best ...

Methods: Twenty-three patients with femoral pseudoaneurysms were treated with ultrasound- guided thrombin injection, between September 2003 and October 2007. Pseudoaneurysm size, dose of thrombin used, result of therapy and complications were prospectively documented. Other aspects analyzed included the type of procedure that caused the pseudoaneurysm (diagnostic catheterization, angioplasty, stent placement), size of endovascular introducer, use of hemostatic device and body mass index (BMI) of patients. results: A total of 27 injections of thrombin were performed. The mean transverse diameter was 3.5 cm. The mean dose of thrombin injected was 666.7 IU. The primary success rate ranged from 19 to 23 (83%). Reperfusion occurred in one pseudoaneurysm. The rate of secondary thrombosis was four in four (100%). No thromboembolic, infectious or alle...

Methods: Series of cases referred from outpatient’s clinic for biopsy of pancreas transplant, between December 2006 and March 2008. Data were collected from medical electronic records for age, sex and histopathology. The indication for the procedure was obtained from medical and laboratory records. Doppler ultrasonography was performed for control and to guide biopsy in real time. Rresults: Twenty patients referred for biopsy of their transplanted pancreas over a one-year period were evaluated. In one patient, biopsy was not performed for having no safe access for ultrasound. It was used 18 gauge needles, mostly automatic-cut type. The main indications were increased blood glucose and pancreatic enzyme levels as well as reduction of urinary amylase. The sonographic aspect of the pancreatic graft was normal in 18 cases. In all 19 biopsies performed, satisfactory samples for ...

Métodos: Vinte e três pacientes com pseudo-aneurismas femorais foram tratados com injeção percutânea de trombina guiada por ultra-som com Doppler, entre Setembro de 2003 e Outubro de 2007. O tamanho do pseudo-aneurisma, a dose de trombina utilizada, o resultado da terapia e as complicações foram documentados prospectivamente. Outros aspectos analisados foram o tipo de procedimento que causou o pseudo-aneurisma (cateterismo diagnóstico, angioplastia, colocação do stent), o tamanho do introdutor endovascular, a utilização dos dispositivos hemostáticos e o índice de massa corpórea (IMC) do paciente. resultados: Um total de 27 injeções de trombina foram realizadas. O diâmetro transverso médio foi de 3,5 cm. A dose média de trombina injetada foi de 666,7 UI.

The rate of secondary thrombosis was four in four (100%). No thromboembolic, infectious or allergic complications occurred. conclusions: Ultrasound-guided percutaneous thrombin injection is the best method for treating femoral pseudoaneurysms caused by endovascular procedures. It presents high rates of success, low recurrence rates and almost no complications.
