[Spiral computed tomography of the renal arteries].

With the recent advent of spiral or helical CT, the ability to acquire large volume of imaging has become possible. Fast scanning of both kidneys, the aorta and the renal vessels can be accomplished during one breathhold. Early reports of CT angiography in the evaluation of renal artery stenosis indicated a sensitivity of 92% utilizing the MIP projection method and 59% utilizing the shaded surface display method. Specificity for both method was approximately 82%. More recent articles reports for hemodynamically relevant renal artery stenosis a sensitivity/sensibility of 96/99%. The introduction of a new multidetector CT technology will probably increase those results and the indication of CT angiography.

[Intermittent claudication in a young patient. A case of isolated fibromuscular dysplasia of the external iliac artery].

Effort-linked intermittent claudication of arterial origin in sportsmen is often attributed to endofibrosis of the external iliac artery. Some knowledge of possible differential diagnoses, in particular the fibrodysplasia, is of importance regarding the therapy involved. Angioplasty treatment of external iliac endofibrosis may be controversial. However, the same does not apply to fibrodysplasia angioplasty, particularly if the latter is accomplished by inserting an endoprothesis. A case of fibromuscular dysplasia of external iliac artery in a 37 year old woman, treated with endoluminal angioplasty and stent, is reported.

Cerebral venous thrombosis and procoagulant factors--a case study.

Cerebral venous thrombosis is a polymorphic clinical entity for which diagnosis has become more frequent with the advent of neuroradiology. The superior sagittal and transverse sinuses are frequently involved, whereas cavernous sinus thrombosis is much less frequent. Inherited resistance to the anticoagulant action of activated protein C (APC resistance), antithrombin deficiency, protein C and S deficiencies, and hyperhomocysteinemia seem to represent major causes of thrombophilia when unusual thromboembolic events (ie, before the age of 45 years) are observed. The authors present the combined occurrence of protein C and protein S deficiencies in a 32-year-old woman, manifested by extensive cerebral venous thrombosis.

[Carotid dissection during childbirth].

A 33-year-old woman presented transient ischemic attach (hemiparesis of the left arm and right amaurosis), 14 days after childbirth, due to dissection of the right carotid that occurred probably during delivery as suggested by right earache at that time. Carotid dissection during pregnancy or after childbirth is rare an exceptional during delivery. Neurological symptoms and arterial lesions were followed by duplex ultrasound.

[Placing of a Nitiol Memotherm prosthesis: personal experience].

The authors report their experience in the placement of a new Nitinol stent. Thirty eight stents were placed in 28 iliac arteries, 3 superficial femoral arteries, 1 popliteal artery, 2 subclavian arteries, and 2 veins of hemodialysis fistulae. The primary success rate was 100%, but several angioplasty balloons have been ruptured due to the specific configuration of the stent. The mean follow-up period was 6 months. Memotherm placement is an easy procedure, but the specific structure of the device makes the manipulation of the angioplasty balloons delicate, especially in tortuous vessels.

[A unusual cause of acute pancreatitis: obstruction of the afferent loop after gastrectomy according to Bilroth II. Apropos of a case and review of the literature].

We report a case of afferent loop obstruction after Bilroth II gastrojejunostomy presenting as acute pancreatitis. This form of presentation is extremely rare; to our knowledge, only 19 cases of acute pancreatitis secondary to afferent loop occlusion in patients with prior Bilroth II gastrojejunostomy have been previously reported in the literature. Obstruction can be caused by kinking, internal herniation, adhesive bands or recurrence of gastric ulcer or cancer. Because conservative management is invariably fatal, diagnosis and surgical treatment must be performed as soon as possible. CT Scan is now considered to be the imaging method of choice for the diagnosis. A case report and review of the literature are presented.

[Agenesis of the right lobe of the liver. Apropos of a case].

The authors report a case of agenesis of the right lobe of the liver, only thirty two cases of which have been reported in the literature since 1870. The differential diagnosis consists of advanced cirrhosis, portal hypertension, neoplastic infiltration of the porta hepatis, gallstones or surgical resection. Agenesis is due to arrest of hepatic development during foetal life. It is generally symptomatic, but may sometimes present in the form of biliary type pain in the right hypochondrium or portal hypertension and may be associated with other anomalies (retrohepatic gallbladder, common bile duct cyst, aplasia of part of the diaphragm, intrathoracic kidney).

Impotence due to corporeal veno-occlusive dysfunction: long-term follow-up of venous surgery.

Corporeal veno-occlusive dysfunction is an important cause of organic impotence and is characterized by increased flow rates to create and to maintain erection during artificial erection produced by intracavernous saline infusion. Sixty-seven patients with this erectile insufficiency underwent penile ligature-resection of deep dorsal vein between 1982 and 1986, and were evaluated by nocturnal plethysmography, pharmacocavernometry as well as a questionnaire about their sexual life for long-term follow-up. The surgical procedure was controlled in the operating room by reduction of the erectile flow rates. Thirty-one patients were potent postoperatively and were able to have satisfactory intercourse. Results after resection were slightly better than after simple ligation of the deep dorsal vein. Four patients had penile glans insensibility resulting from the surgical dissection. There were 7 relapses several months after the procedure due to leakage through other deeper veins. Eight failures were due to additional psychogenic disorders or to neurologic disease not accurately diagnosed before the treatment because they all developed normal papaverine-induced erection after venous surgery while before it they only developed a slight tumescence. Reduction of the erectile flow rates within normal values was impossible during surgery in 3 patients. Eleven failures were due to concomitant arterial disease. Resection of the deep dorsal vein can restore penile erection in patients with cavernovenous leakage in about 50% of well-selected patients.

Role of the captopril test in renovascular hypertension: a case report.

This article reports the case of a rapidly severe stenosis of the right renal artery, causing uncontrolled hypertension. After failure of a percutaneous transluminal renal angioplasty, which provoked the thrombosis of the vessel, a surgical revascularization was performed after +/- eighteen hours of renal ischemia. Blood pressure, blood urea nitrogen and serum creatinine returned to normal values. A dramatic improvement of the right renal function was attested at the hippuran scintigraphy after a dose test of captopril. The results of renographic studies obtained in this clinical case underline the role of the captopril radionuclide test in detection and follow-up after treatment of renovascular hypertension.
