Needle aspiration/biopsy of the spine in suspected disc infection.
Closed needle aspiration/biopsy was performed in 19 patients with suspected spinal disc space infection. A precise diagnosis was made, from the material obtained in 13 (68%); the infecting organism was isolated in 11 and malignant tumour diagnosed histologically in two. There were no important complications. The procedure which is described in detail is simple to perform and can be carried out early in the course of a patient's stay in hospital, thereby enabling prompt treatment.

Ascending lumbar venography in the diagnosis of lumbar disc lesions.
Fifty-five patients suffering from low back pain with or without sciatica were submitted to ascending lumbar venography. Six patients had anatomical variations which prevented adequate catheterization and 6 had equivocal radiographic appearances, which we could not assess. Fourteen patients had normal venograms but in 29 an abnormality was demonstrated. These 43 patients were then submitted to radiculography and, where appropriate, surgery. The 14 patients with normal venograms also had normal radiculograms; while the 29 with abnormal venograms had an abnormality confirmed on radiculography and/or surgery. However, in 10 of the patients the lesion was found to be one disc space lower than that demonstrated on venography; Side-effects were very few, and the procedure can be used on out-patients. This technique would appear to be a useful addition to the radiological investigation of the spine.

Emergency arteriography in acute gastrointestinal bleeding.
Emergency arteriography was carried out on 35 patients with acute gastrointestinal bleeding, in 31 of them within two hours of active bleeding (a haematemisis; a diagnostic change in central venous pressure, pulse rate, or blood pressure; or gastric aspiration of fresh blood). A definite site of bleeding was identified in 27 patients (77%)-this being a small-intestinal vascular abnormality in three--and a probable site in three. Confirmation of the bleeding site was obtained in 20 out of 23 patients treated surgically. An intra-arterial vasoconstrictor infusion was given as a temporary measure before surgery in seven patients, only one of whom showed active bleeding at operation. An intra-arterial vasoconstrictor infusion was tried as definitive treatment in an additional 10 patients, but in four out of seven with a chronic ulcer bleeding recurred after 5-68 hours and was therefore treated surgically. We recommend the diagnostic use of arteriography in patients with reliable evidence of active bleeding if its site cannot be determined by endoscopy. We do not recommend its therapeutic use in those with a chronic ulcer, except to facilitate resuscitation before surgery; further studies are needed to define its role in those with an acute lesion.

Vertebral trephine biopsy.
Vertebral trephine biopsy is a safe and swift method of diagnosis of vertebral abnormality. The procedure is no more disturbing for the patient than lumbar puncture, and saves the patient, radiologist and clinician, considerable time and effort.

Gianturco self-expanding stents: clinical experience in the vena cava and large veins.
Twenty-five patients with stenosis of the vena cava (21) and other large veins (4) have been treated with self-expanding Gianturco metallic stents. Eighteen patients had superior vena cava syndrome. In 17, the stricture was due to malignant superior vena cava compression recurrent after maximum tolerance radiotherapy and/or chemotherapy. In 16 of these patients there was early symptomatic relief. In 1 patient with a benign posttraumatic superior vena cava stricture, the stenosis was not relieved, and occlusion occurred after 1 month. Stenoses associated with dialysis shunts were relieved in 2 other patients. Two malignant and one benign inferior vena cava stenoses were relieved either until death, or in the benign case, for 30 months. One malignant subclavian vein obstruction occluded after 24 h due to stent misplacement and another with extrinsic mediastinal compression remained patent until death, extensive thrombus having been lysed prior to stent placement. The results of this short series suggest that the Gianturco self-expanding stent in the vena cava and large veins is easy and safe to place, and in most cases produces almost immediate palliation of the distressing effects of venous obstruction, often in a preterminal and inoperable patient.

Role of the Gianturco expandable metal stent in the management of tracheobronchial obstruction.
This paper reports our experience in treating localized airway obstruction with expandable metal stents. Nine patients were treated for malignant obstruction and 6 for benign obstruction. The main indications for treatment were imminent asphyxia, breathlessness and/or repeated chest infections. All but 2 patients had received other treatments before referral. Seven patients with malignant obstruction had extrinsically compressed airways and all derived a sustained symptomatic improvement. Two patients with recurrent tracheal obstruction caused by intraluminal tumor gained lasting relief with the use of a covered expandable metal stent. All 6 patients with benign strictures were improved, although 2 developed recurrent obstruction caused by granulation tissue growing within and beyond the stent. It is concluded that the expandable metal stent provides an effective and noninvasive method of relieving large airway obstruction. As the long-term tissue tolerance to this type of stent is not known, caution is advised in the management of benign strictures. In patients with malignant obstruction, however, the expandable metal stent would appear to have considerable potential as a palliative treatment.

Intra-arterial prostacyclin compared to Praxilene in the management of severe lower limb ischaemia: a double blind trial.
The effectiveness of a 72 h. intra-arterial prostacyclin infusion has been compared to that of naftidrofuryl oxalate (Praxilene) in a double blind study of 29 patients with ischaemic rest pain in 30 legs. Long-term relief of symptoms was achieved in 14 legs (47%) and major limb amputation avoided in 18 (60%). No significant difference was demonstrated between the results of prostacyclin infusion and those of Praxilene.

Transjugular intrahepatic portosystemic stent-shunt.
The transjugular intrahepatic portosystemic stent-shunt is a non-surgical method for creating a portosystemic shunt. Early reports suggest that it is effective for treating portal hypertension and variceal bleeding. This review describes the technique and discusses the indications and complications.
