Article: Prediction of evolution toward brain death upon admission to ICU in comatose patients with spontaneous intracerebral hemorrhage using simple signs.
[show abstract] [hide abstract]
ABSTRACT: The aim of the study was to identify the predictors of brain death (BD) upon admission to the intensive care unit (ICU) of comatose patients with spontaneous intracerebral hemorrhage (ICH). Patients admitted in our ICU from 2002 to 2010 for spontaneous ICH and placed under mechanical ventilation were retrospectively analyzed. Of the 72 patients, 49% evolved to BD, 39% died after withdrawal of life support, and 12% were discharged alive. The most discriminating characteristics to predict BD were included in two models; Model 1 contained ≥3 abolished brainstem responses [adjusted odds ratios (OR) = 8.4 (2.4, 29.1)] and the swirl sign on the baseline CT-scan [adjusted OR = 5.0 (1.6, 15.9)] and Model 2 addressed the abolition of corneal reflexes [unilateral/bilateral: adjusted OR = 4.2 (0.9, 20.1)/8.8 (2.4, 32.3)] and the swirl sign on the baseline CT-scan [adjusted OR = 6.2 (1.9, 20.0)]. Two scores predicting BD were created (sensitivity: 0.89 and 0.88, specificity: 0.68 and 0.65). Risk of evolution toward BD was classified as low (corneal reflexes present and no swirl sign), high (≥1 corneal reflexes abolished and swirl sign), and intermediate. Simple signs at ICU admission can predict BD in comatose patients with ICH and could increase the potential for organ donation.Transplant International 03/2013; · 2.92 Impact Factor -
Article: MR features of inflammatory hepatic adenoma.
[show abstract] [hide abstract]
ABSTRACT: Hepatocellular adenomas are a group of benign tumors forming three molecular pathological subgroups. Inflammatory hepatic adenomas have typical MR findings, which help for diagnosis: hypersignal on T2W sequences, hyperintense peripheral signal band, strong arterial enhancement, with persistent enhancement in delayed phase.Gastroentérologie Clinique et Biologique 12/2012; · 0.80 Impact Factor -

Article: Femoral venous catheter: a misleading cause of gas in the liver.
[show abstract] [hide abstract]
ABSTRACT: The presence of a femoral venous catheter could be associated with gas presence in the hepatic veins. This entity should be recognized to avoid a misdiagnosis of gas presence in the portal veins or in the biliary tract. Objectives are to assess: 1) the incidence of gas presence in the hepatic veins in intensive care unit patients explored by abdominal computed tomography scan; 2) the rate of gas presence in the liver in intensive care unit patients with a catheter inserted in the femoral vein; and 3) the specific imaging features. A retrospective study in a medical intensive care unit in a teaching hospital in France. All consecutive abdominal computed tomography scans performed in intensive care unit patients between 2008 and 2010 were retrospectively reviewed independently by an intensivist and a radiologist. Presence of gas in the liver was noticed and its location was specified using multiplanar reconstruction. We analyzed 235 computed tomography scans (performed in 207 patients). Gas was identified in the liver on 10.2% of computed tomography scans. Gas was located in the hepatic veins in 12 cases (50%), in the biliary tract in ten cases (41.7%), and in the portal veins in two cases (8.3%). All patients with gas in the hepatic veins had a femoral venous catheter. Characteristics of gas location within the hepatic veins on computed tomography scan axial views were not different from those of gas located in the biliary tract or in the portal venous system. Gas was present in the hepatic veins in 12 of 83 (14.5%) of the computed tomography scans with a femoral venous catheter and was associated with gas presence in other vessels of the inferior vena cava system in five of 12 (41.7%) cases. Gas located in the hepatic veins related to femoral venous catheter is a frequent cause of gas in the liver in intensive care unit patients. This imaging feature could be misleading. Multiplanar reconstruction should be performed to differentiate this aspect from those of gas in the biliary tract or in the portal venous system.Critical care medicine 06/2011; 39(11):2447-51. · 6.37 Impact Factor -
Article: Relapse of Crohn's disease following ileal pouch-anal anastomosis: MDCT and MR features.
[show abstract] [hide abstract]
ABSTRACT: OBJECTIVE: The purpose of our study is to use MDCT and MR imaging to describe the normal ileal pouch and to identify features of Crohn's disease (CD) relapse in patients after ileal pouch-anal anastomosis (IPAA). CONCLUSIONS: After total colectomy followed by IPAA, features, optimally evaluated with pelvic MRI, such as fistulas, abscesses, pouch inflammation, and stenoses, indicate CD relapse. Although uncommon, radiologists should be aware that these imaging features strongly favor this diagnosis.Abdominal Imaging 05/2011; 37(1):53-60. · 1.73 Impact Factor -
Article: CT and MRI features of ileostomies.
[show abstract] [hide abstract]
ABSTRACT: OBJECTIVE: The purpose of this article is to describe CT and MRI features of normal anatomy, variants, and pathologic conditions of different ileostomies. CONCLUSION: Multiplanar imaging techniques are useful to identify the complications related to stoma construction and preexisting disease. Understanding the indications for ileostomy construction, surgical techniques, and postoperative anatomy is important for differentiating normal and abnormal imaging features.American Journal of Roentgenology 03/2011; 196(3):577-84. · 2.78 Impact Factor -
Article: [Imaging of acute pancreatitis].
[show abstract] [hide abstract]
ABSTRACT: The radiological management of acute pancreatitis is well codified. The positive diagnosis of acute pancreatitis is based on clinical and biological signs. However, imaging helps for in diagnosing severity and complications. The etiological diagnosis should strive to detect gallstones by an abdominal ultrasound to be performed within 24 hours of onset of symptoms. The severity is assessed at 48-72 hours per scanner after contrast media injection, according to the classification CTSI. It is important to avoid the two following pitfalls: realising the scanner too early, which could be falsely reassuring because necrosis of the pancreatic parenchyma appears at least 48 to 72 hours after onset of clinical signs, and dispense with ultrasound at 24 hours, because the gallstones are visible only in 50% of the scanner. Imaging helps to manage some complications of acute pancreatitis: in case of infectious complications, remember to perform a needle aspiration or percutaneous drainage of fluid collections; in case of haemorrhage from rupture of a false aneurysm, the treatment of choice is embolization for hemostasis under radiological guidance.La Revue du praticien 02/2011; 61(2):214-21. -
