The effect of phenylbutazone on acute hemorrhagic pancreatitis in the rat.

The effect of phenylbutazone on acute experimental pancreatitis was investigated in the rat. Severe necrotico-hemorrhagic pancreatitis was produced by intraductal injection of trypsin. Pretreatment by phenylbutazone did not alter the mortality rate but reduced the severity of pancreatitis as was demonstrated by histological quantification (total score 13.35 +/- 0.80 in treated rats versus 17.67 +/- 0.69 in the control group; P less than 0.01). The protective effect of phenylbutazone seems to be related to the specific anti-inflammatory properties of the drug and not to inhibition of prostaglandin synthesis.

[Arterial false aneurysm after total hip arthroplasty. A case report]. / Faux anévrysme artériel sur arthroplastie de hanche. A propos d'un cas.

Vessel damage during implantation of a total hip arthroplasty is exceptional (0.2-0.3% incidence). We observed a case of false aneurysm of the common femoral artery diagnosed in a pauci-symptomatic patient seven months after total hip arthroplasty. The vessel was damaged by a fragment of cement in contact with the artery. Treatment consisted in extraction of the cement fragment and insertion of a vascular prosthesis after dissection and ligature of the pseudoaneurysm. A review of the literature of vascular complications after prosthetic hip surgery was undertaken. Early complications include acute bleeding or ischemia while late complications include pseudoaneurysm or arteriovenous fistulization. Predisposing factors are: infection, repeated contact between the implants and arterial walls, overly medial reaming of the acetabulum, intrapelvic cement spikes, and use of Hohmann retractor. We detail here the clinical signs, diagnostic approach, and natural course of arterial false aneurysm resulting from intra-pelvic cement leakage.

[Interruption of the inferior vena cava by the DIL filter. Experience apropos of 34 cases]. / Interruption de la veine cave inférieure par le filtre DIL. Expérience à propos de 34 cas.

Endocaval filters are often used to prevent pulmonary embolism but they have a number of disadvantages. The DIL filter, made of a memory metal wire, is intended to male up for some of these disadvantages. It acts by modifying the shape of the inferior vena cava, which it filters through its meshed loops. It is inserted percutaneously, causes little trauma, and its release is progressive. However, it requires measuring the caliber of the inferior vena cava. This filter was inserted in thirty-four patients over a period of 13 months. One filter has migrated. No recurrence of pulmonary embolism and no thrombosis of the inferior vena cave occurred.

[Late diagnosis of a traumatic pseudo-aneurysm of the subclavian artery]. / Diagnostic tardif d'un pseudoanévrysme traumatique de l'artère sous-clavière.

The authors report a rare case of subclavian pseudoaneurysm diagnosed six months after a left clavicular fracture. The leading symptoms were pain and claudication in the left arm related to peripheral embolization. The essential diagnosis was made by selective arteriography followed by arterio-CT. Peripheral embolization or brachial nerve compression are the most common presentations of subclavian pseudoaneurysms. To avoid such late complications, the authors emphasize the importance of the initial vascular examination of the shoulder after blunt trauma with or without clavicular fracture. Surgery is imperative and the use of autologous vein graft is the method of choice.

[2 cases of giant aneurysm of the splenic artery: contribution of Doppler echography]. / Deux cas d'anévrisme géant de l'artère splénique: apports de l'écho-Doppler.

Excluding the extremely uncommon cases of completely thrombosed aneurysm, color Doppler US plays a leading part in establishing the diagnosis of splenic artery aneurysm. The color Doppler US patterns are typical, as illustrated in the two reported cases of splenic artery aneurysm larger than 5.0 cm.

[Adventitial cyst of the common femoral artery: computerized tomography demonstration of the articular origin of this disorder]. / Le kyste adventiciel de l'artère fémorale commune: démonstration tomodensitométrique de l'origine articulaire de cette pathologie.

Cystic adventitial disease is very rarely described in the common femoral artery, the usual location being the popliteal artery. CT in this patient shows the extension of an enlarged bursa of the psoas muscle reaching the cyst in the arterial wall.

Giant splenic artery aneurysm presenting as unusual cause of obstructive jaundice.

Giant splenic aneurysms larger than 8 cm (GSAA) are rare and often asymptomatic but present an increased risk of dramatic rupture, a life-threatening complication. The management of these aneurysms is especially challenging. We probably report the first case of GSAA revealed by clinical mechanical jaundice due to direct compression of the biliary tree. The lesion was diagnosed during abdominal ultrasound in a 68-year-old patient but determination of the specific splenic origin and extensive anatomic preoperative evaluation were achieved by MDCT. The case illustrates the new high quality performances of MDCT in the evaluation of complex vascular abdominal situations and is presented with a brief review of the relevant literature.

Colour duplex sonographic and multislice spiral CT angiographic diagnosis of ulnar artery aneurysm in hypothenar hammer syndrome.

We report a case of hypothenar hammer syndrome secondary to a thrombosed aneurysm of the ulnar artery in a 36-year-old patient presenting with pain due to compression of the ulnar nerve in the Guyon's canal. The initial diagnosis was made by colour Duplex sonography but complete assessment of the thrombosed aneurysm was performed by multislice spiral CT angiography (msCTa). This case illustrates the potential of msCT as an alternative to conventional arteriography.
