Inferior mesenteric arteriovenous fistula associated with portal hypertension and acute ischemic colitis. Successful occlusion by intraarterial embolization with steel coils.

The authors report a case of postoperative arteriovenous fistula between the inferior mesenteric vessels. This fistula was revealed by portal hypertension, with bleeding esophageal varices, ascites, and encephalopathy, and by acute ischemic colitis. Histologic examination of the liver was normal. All of the symptoms disappeared after transcatheter embolization of the fistula with stainless steel coils. This case report favors the reality of the so-called "forward" portal hypertension and suggests that inferior mesenteric arteriovenous fistula might be a factor predisposing to nonocclusive ischemic colitis.

Renovascular hypertension: easier diagnosis and treatment with intravenous renal arteriography and percutaneous transluminal dilatation.

For the diagnosis of renovascular disease, the authors propose the use of intravenous arteriography with photographic subtraction as the method of choice and advise the use of pyelogram wash-out to assess the functional significance of the stenosis. Furthermore they report their experience with percutaneous transluminal dilatation in 41 patients (10 fibrotic--31 atherosclerotic renal artery stenoses) and suggest that this method is valid alternative to surgery specially in poor risk patients. A controlled trial of this method versus surgery needs however to be undertaken to define the respective roles of these treatments.

Onset and offset of brain events as indices of mental chronometry.

Analysis of single-trial electroencephalogram waveforms in a reaction time task demonstrated that the onset and offset values of event-related potentials can be used as indices of the duration of information processing. Two negative waves have been identified which peak at different times in different regions of the scalp, with the second overlapping the last part of the first. These waves are related in different ways to the duration of perceptual processing.

[Intravenous pyelography with visualization of renal arteries and pyelogram wash-out, as the method of choice for the diagnosis of renovascular hypertension (author's transl)].

The authors review the various techniques of intravenous arteriography before an excretory urogram and discuss their role in the etiological diagnosis of hypertension. Detection of renovascular disease classically implied Seldinger arteriography, with its limited indications, because of side effects and cost. This classical approach should now be systematically replaced by the visualization of renal arteries during the intravenous pyelography procedure which appears to be a method more effective, as well as less expensive and hazardous. The pyelogram wash-out should still be performed when the visualization of the renal arteries is poor because of its value in the screening for renovascular hypertension. Furthermore, when a renal artery stenosis is clearly defined, the wash-out of the pyelogram should also be performed because of its prognostic value. As the classical approach for the etiological diagnosis of hypertension, this technique has limited indications. It is indicated in severe hypertension in the young, when medical treatment does not control blood pressure satisfactorily or when renal failure progresses rapidly. Furthermore, this technique allows a non traumatic follow up of operated or dilated stenoses.

Value of combined intravenous renal arteriography and pyelography in the diagnosis of renovascular hypertension.

1. The technique of combined intravenous renal arteriography and pyelography is described and results in 848 hypertensive patients are reported. 2. The procedure was tolerated better than Seldinger arteriography and the diagnostic accuracy for renal artery stenosis was 95%. 3. The prevalence of renovascular disease was 7%. 4. Cost-effectiveness calculations favour combined intravenous arteriography and pyelography rather than the usual approach based on assessment of the indications for Seldinger arteriography from clinical and urographic signs.

[Focal nodular hyperplasia of the liver discovered and biopsied during hysterectomy for fibroids secondarily treated by paramendian bisectoriectomy with cure for more than one year (author's transl)].

The authors emphasise the necessity for rigourous criteria of histological identification, the basis of the therapeutic decision; the risk on onset of hemoperitoneum suggests radical treatment before the compliction, considering the operative risk, in relation to the site of the lesions and their macroscopic appearance. The notion of rareness and the histogenesis of the disease are also considered.

Gastrointestinal bleeding due to chronic portal vein thrombosis in ulcerative colitis.

The authors report the case of a patient suffering from ulcerative colitis, who had several episodes of digestive hemorrhage due to portal hypertension. Portal hypertension was secondary to chronic portal vein thrombosis. This diagnosis was made on the venous phase of celiac and mesenteric angiography. The authors review the published cases of ulcerative colitis with portal vein thrombosis and discuss the possible etiologic factors: hypercoagulability, thrombocytosis, and intraabdominal sepsis.

[Segmentary bronchial atresia. One observation (author's transl)].

This study was done on a case of segmentary bronchial atresia of the left upper lobe. It is an exceptional congenital malformation, as only 47 observations have been so far recorded. Diagnosis was essentially radiological. The standard chest X ray and tomographies revealed an area of segmentary and lobar transparency surrounding a para-hilar lump. Diagnosis was confirmed by bronchography revealing the lack of injection into the atretic bronchus. Possible infectious complications and the evolution of bronchiectasis and obstructive emphysema justify the surgical exeresis.
