Coiling of a vulvar arterio-venous malformation.

The authors report the case of a 13-year-old girl with a painful vulvar swelling and abnormal vaginal bleeding, increasing in size after trauma. With MRI (GE Signa HDx 1.5 Tesla), it is diagnosed as an arterio-venous malformation arising from the left superior femoral artery.

A multicentre evaluation of the Medtronic AVE Flexible Iliac Bridge Stent in the iliac arteries (the first study).

Purpose: To investigate the short term and 6 month outcomes of a recently introduced iliac stent (the Medtronic AVE Flexible Iliac Bridge Stent).

Method: One hundred and sixteen patients, 122 limbs from 6 European sites with atherosclerotic occlusive disease were included if they either had a full occlusion or there was a residual gradient >10 mmHg following PTA. Clinical, haemodynamic and Duplex outcomes were recorded to 6 months.

Splenic abscess caused by Peptostreptococcus species, diagnosed with the aid of abdominal computerized tomography and treated with percutaneous drainage and antibiotics: a case report.

We describe herein a 63-year-old patient with a splenic abscess due to Peptostreptococcus spp., diagnosed with the aid of abdominal computerised tomography and treated with ultra-sound guided percutaneous drainage and antibiotics. The bacteriological characteristics of splenic abscesses are discussed.

Progression of atherosclerosis at one-year follow-up seen with volumetric intravascular ultrasound in femoropopliteal arteries.

Volume measurements derived from intravascular ultrasound (IVUS) images assessed with an automated contour analysis system are accurate and reproducible. However, it is unknown to what extent plaque volume may change at follow-up. Therefore, the purpose of this longitudinal study is to examine whether IVUS is a sensitive means to identify progression of atherosclerosis and its derived primary end point plaque volume at 1-year follow-up.

Reproducibility of volumetric quantification in intravascular ultrasound images.

The reproducibility of volume measurements in intravascular ultrasound (IVUS) images derived from separate pull-back manoeuvres remains to be elucidated. Patients (n = 23) were imaged with IVUS prior to (first series) and following percutaneous transluminal angioplasty (PTA) (second series). In 15 patients, one matched vascular segment (3-4 cm in length), not subjected to PTA, was used for analysis of lumen, vessel and plaque volume using an automated contour analysis system.

Intravascular ultrasound predictors of restenosis after balloon angioplasty of the femoropopliteal artery.

Objectives: To determine intravascular ultrasound parameters related to restenosis following percutaneous transluminal balloon angioplasty (PTA) of the femoropopliteal artery.

Design: Prospective study.

Materials And Methods: Patients were studies with intravascular ultrasound before and after angiographic successful PTA (n = 114).

Effect of balloon angioplasty in femoropopliteal arteries assessed by intravascular ultrasound.

Objective: To study the effects of balloon angioplasty (PTA) of the femoropopliteal artery with intravascular ultrasound (IVUS).

Materials And Methods: Corresponding IVUS cross-sections (n = 1033) obtained before and after PTA from 115 procedures were analysed. Vascular damage including plaque rupture, dissection and media rupture was assessed.

High failure rate of cementless threaded acetabular cups: a radiographic and histologic study in the goat.

We studied the fixation of the Mecron cementless titanium screw cup radiographically and histologically in 20 dwarf-goats after periods of 0, 6, 26 and 52 weeks. In only 3 goats did histology show good bone-implant contact, whereas in the other 17 goats a fibrous membrane interface was seen. This high failure rate is caused by the poor primary fixation and should be a warning against the use of this implant.

Radiographic loosening of cementless threaded acetabular cups. No additional diagnostic value of arthrography in 30 patients.

We compared arthrography with plain radiographs in 30 consecutive patients having a clinical diagnosis of loosening of a smooth-threaded acetabular prosthesis (Mecron, Berlin). Leakage of contrast at the interface between the ring and the bone on the medial side of the prosthesis was seen in 21 patients. Loosening of the cup was also visible on the plane radiographs and loosening was confirmed in all these patients at revision surgery.

Radiographic evaluation of developing instability of the Mecron cementless, threaded acetabular prostheses.

Purpose: To evaluate radiographically the history of the Mecron acetabular prosthesis.

Material And Methods: The pelvic radiographs of 350 consecutive patients with a smooth threaded acetabular prosthesis type Mecron were retrospectively evaluated (follow-up 1 to 6 years, mean 4 years). A demarcation zone seen at the medial side of the prosthesis was graded from 0 (absent) to 3 (severe).

Failure of the Mecring screw-ring acetabular component in total hip arthroplasty. A three to seven-year follow-up study.

We prospectively studied the results of 411 consecutive total hip arthroplasties with a Mecring screw-ring acetabular component inserted without cement combined with a Stanmore femoral stem inserted with cement. The duration of follow-up ranged from three to seven years (mean, four years and six months). Three hundred and thirty-one patients (378 hips) were available for physical examination and had a complete set of radiographs.

Reproducible radiographs of acetabular prostheses. A method assessed in 35 patients.

35 patients with a smooth, threaded acetabular Mecron type prosthesis were examined with the aid of a table top with wiremarkers and a fixed 30-degree wedge to allow for reproducible positioning. Under fluoroscopic control, pelvic and spot films were made. The inter- and intraobserver variability of anteversion and inclination angle measurements of the prostheses had a standard deviation of less than 1 degree.

Eosinophilic enteritis presenting as acute abdomen: US features of two cases.

Eosinophilic enteritis is a rare disease which may mimic acute abdominal emergency. Two sonographically documented cases are presented, which were subsequently proven at operation. Although the sonographic features of severe echolucent bowel wall thickening were not specific, combination with clinical and laboratory data may suggest the correct diagnosis.

[Bacterial ileocecitis: a "new" disease].

In cases of clinical suspicion of an acute appendicitis sonography uncovers another disease as the real cause of the symptoms in about one-quarter of such cases. Bacterial ileocaecitis is most frequently diagnosed (11.6% of N = 786).

Changes in appearance of amniotic fluid during pregnancy - the macroscore.

During the first two trimesters of pregnancy the amniotic fluid is clear and yellow; during the third trimester the amniotic fluid becomes colourless; then, approximately from the 33rd-34rd week on, cloudiness and flocculation occur, at first very slowly, after the 36th-37th week steadily faster (Tab. I). At term, the amniotic fluid is moderately cloudy and contains a moderate number of flakes of vernix.
