[Helical CT compared to ERCP in obstructive biliary pathology].

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is the examination of choice in the diagnosis of biliary tract pathology although newer, less invasive techniques with high diagnostic sensitivity should be evaluated. The aim of this study was to evaluate the diagnostic efficacy of helical computed tomography (CT) in bile duct obstruction, particularly in choledocholithiasis. PATIENTS AND METHODS: Forty-four patients with suspected bile duct obstruction were prospectively evaluated. Helical TC was carried out 12 hours before ERCP and patients were grouped according to risk of choledocholithiasis. RESULTS: Choledocholithiasis was found in 20 patients (45.4%). Helical TC identified this pathology in 17 and correctly ruled it out in 18 of 24 patients (S: 85%, E: 75%, positive predictive value 74%, negative predictive value 85.7%. Of the patients with choledocholithiasis, bile duct dilatation was found in 18. Helical TC correctly diagnosed this pathology in 16 of the 18 patients (88.8%). Helical TC correctly diagnosed one of two patients (50%) with choledocholithiasis and normal bile ducts. CONCLUSIONS: Helical TC is effective in the diagnosis of choledocholithiasis but is not sufficiently accurate to be used in the screening of this entity.

[Idiopathic brain herniation in the middle ear and mastoid].

Idiopathic brain herniation into the middle ear and the mastoid process is a rare clinico-pathological entity, with only 41 cases described in the literature. It should be suspected in presence of spontaneous otoliquorrhea/rhinoliquorrhea, refractory serous otitis media, or meningitis following acute otitis media in an adult. A new case is presented, with a brief review of the pathogenesis, clinico-pathological, and radiological characteristics of these lesions.

Transvenous coil embolization of an intrahepatic portosystemic shunt in a dog.

To treat an intrahepatic portosystemic shunt in a young dog, thrombogenic material was placed into the vessel lumen (transvenous coil embolization) under fluoroscopic control. One coil was placed into the shunt, followed one month later by two additional coils. Transvenous embolization may become a useful method in the treatment of some portosystemic shunts.

[Carotid stenosis and lacunar infarct].

INTRODUCTION: Perforating artery disease is still the main cause of lacunar infarcts (LI), while the relationship between this type of ischemia and carotid stenosis (CS) is controversial. OBJECTIVE: To assess the association between CS and LI in patients with criteria of localized ischemia in the carotid territory separately analyzing isolated LI and multiples LIs. PATIENTS AND METHODS: Three hundred and thirty patients with a first episode of cerebral infarct in the area supplied by the carotid artery were registered prospectively. There were 205 LI (135 isolated and 70 multiple) which could be differentiated from 125 non-lacunar infarcts (NLI). The vascular risk factors were determined and the degree of carotid stenosis measured by duplex-colour ultrasound exploration. RESULTS: In the isolated LI group the frequency of presentation of CS greater than 50% was 22% for the artery ipsilateral to the LI and 8% for the contralateral artery. For significant CS (> 70%) frequencies of 14% (ipsilateral) and 8% (contralateral) were observed. On comparative analysis with the NLI group, the presence of stenosis greater than 50 to 70% was significantly higher in these for both ipsilateral and contralateral arteries. In the LI group, isolated CS was significantly more frequent on the side which was homolateral to the ischemia as compared to its isolated presence on the contralateral side (22/30 vs 4/12; OR: 5.5 [95% CI: 1.2-23]). Ipsilateral CS greater than 70% behaved as a factor which was significantly associated with the multiple LI subtype with a unilateral pattern. CONCLUSION: CS should be considered a risk factor for LI.

[Arteriosclerotic aneurysms isolated from the internal iliac artery].

A case of an isolate, symptomatic, atherosclerotic aneurysm of the left internal iliac artery is presented. A review from this very rare type of pathology reveal that clinical symptoms depends on the comprised anatomical structures. Diagnosis was made by rectal or vaginal touch, ultrasonography and CT. The operatoire mortality rate is high when aneurysms are ruptured.

[Inflammatory aneurysm of the abdominal aorta. Apropos of a case].

The presentation of a case of inflammatory aneurysm in abdominal aorta and its bibliographic revision, makes evident the short knowledge of its etiopathogenesis and the need of TAC for its differential diagnosis and its treatment and correct follow up.
