[Doppler ultrasound and aortic regurgitation. Evaluation of the sensitivity and specificity of Doppler findings].

Purpose: The purpose of this study was to determine the sensitivity and specificity of arterial Doppler findings of aortic regurgitation to assess if the amplitude of changes of Doppler tracings can accurately quantify the degree of regurgitation.

Patients And Methods: We analysed and compared the arterial Doppler tracings and echocardiograms of 250 patients.

Results: Even if the obvious pitfall of vascular stenoses is avoided, the global sensitivity of arterial Doppler findings for aortic regurgitation remains weak (30%).

[Screening for hepatocarcinoma in a cohort with cirrhosis mainly of alcoholic origin].

Objectives: To assess the feasibility and efficiency of the screening for hepatocarcinoma in a cohort of cirrhoseis mainly of alcoholic origin.

Patients And Methods: 293 patients with cirrhosis, among them 186 (63.5%) from alcoholic origin, were included in a surveillance programme for hepatocarcinoma by carrying out liver ultrasonography and alpha-foetoprotein dosage every 6 months.

[Continent urinary diversion and calculus].

The continent urinary diversion is the technique usually used to replace the urinary bladder after total cystectomy The formation of calculi in the pouch is a frequent late complication. We have treated successfully with extra corporeal wave shock lithotripsy (ESWL) two patients who have developed calculi in their pouch two years after realisation of an ileal urinary diversion (Indiana pouch). E.

[Insidious growth of peritoneal cysts several years after pelvic surgery. Ultrasonographic and x-ray computed tomographic aspects].

Introduction: The aim of the present study is to call the radiologist's attention to peritoneal cysts (PC) when making the diagnosis of cystic masses in patients with a history of long-standing abdominal surgery.

Material And Methods: Four cases of histologically proven peritoneal cysts, discovered 2 to 21 years after abdominal surgery were studied with ultrasonography (US) and computed tomography (CT). The symptoms leading to the diagnosis of PC included abdominal pain, discomfort and palpable mass.

Colour Doppler imaging of an ascending pharyngeal artery arising from the internal carotid artery.

We present two cases of an extracranial collateral of the internal carotid artery. The descriptions include Doppler recording and colour flow-mapping. The report underlines the epidemiological, embryological and anatomic features (including Doppler characteristics) of the variant, with a view to helping sonographers whenever the carotid examination proves difficult.

Screening for hepatocellular carcinoma: a regained enthusiasm due to new therapeutic options?

Screening for hepatocellular carcinoma arising in cirrhosis has been recommended for a long time. However, the results of this screening have been disappointing mainly because of poor health status and liver function in patients with cirrhosis. Indeed, when an hepatocellular carcinoma is discovered by screening, surgical resection can rarely be performed.

The density, contour, and thickness of the pancreas in diabetics: CT findings in 57 patients.

Insulin has a trophic effect on pancreatic acinar tissue, so the pancreas might be expected to atrophy in persons who have diabetes. Accordingly, we analyzed the density, contour (smooth or lobulated), and thickness of the pancreas on CT scans of diabetic patients and compared the results with those in control subjects. The prevalence of pancreatic lobulation (incisurae deeper than 2 mm) and its correlation with age in diabetic and control subjects were determined.

Klebsiella pneumoniae liver abscess with septic endophthalmitis. The role of computed tomography.

Klebsiella pneumoniae liver abscess associated with septic endophthalmitis is a rare observation. To our knowledge, only 10 cases have been reported in the international literature. We report a further case of complication occurring in an adult woman with hypothyroidism, and comment on the role of CT for the work-up.

[Pancreatitis and choledochal cyst].

A six years old girl was rushed to hospital with an acute abdomen. Because of the age of the patient, the clinical examination and the usual biology we diagnose an acute appendicitis. The fortuitous measuring out of the pancreatic enzymology allows us to correct our first diagnostic into the one of pancreatitis with angiocholitis.
