[Angiography in thoracic outlet syndrome].

The thoracic outlet syndrome is a changeable clinical syndrome caused by compression of the neurovascular bundle of the upper extremity, within the cervicoaxillary channel. From April 1980 through May 1995, 24 patients with clinical thoracic outlet syndrome were evaluated by selective arteriography. The diagnosis was confirmed in seven patients, in 14 the exam was normal and in the last three cases another arterial pathology was detected--subclavian artery occlusion, subclavian artery kinking and vertebral steal syndrome. The authors' aim is to emphasize arteriography as a diagnostic exam for thoracic outlet syndrome, very useful in the detection and localization of arterial compression. It also allows the diagnosis of other arterial entities.

[The use of endoprosthesis in superior vena cava syndrome caused by lung neoplasms].

We present six cases of superior vena cava syndrome caused by a malignant tumor that were treated by percutaneous endoprostheses. The technique is described and the results evaluated. In one case there was acute thrombosis of the endoprosthesis that was treated by urokinase. No other complications were observed. A patient died one month later due to progression of the tumor. The remaining cases were asymptomatic for longer than 6 months. It was concluded that endoprostheses for superior vena cava syndrome are efficient, with quick improvement of the symptomatology.

[Hemangiopericytoma].

A case of hemangiopericytoma located in the left upper thigh is presented. The literature is reviewed, particularly the clinical aspects and reference is made to arteriography and preoperative embolization.

[The transjugular intrahepatic portosystemic shunt].

The case of a 66-year-old woman with several episodes of hemorrhage by esophageal varices and ascites due to portal hypertension is presented. Despite 4 sessions of endoscopic sclerotherapy bleeding recurred. A transjugular intrahepatic portosystemic shunt was performed. In the 10 months following the intervention, there was no further hemorrhage, the ascites disappeared and the shunt is open.

[Renal artery angioplasty].

In the 59 hypertensive patients submitted to percutaneous transluminal angioplasty (PTA) of the renal artery, there was an immediate success in the blood pressure in 91.5% and a later one of 79.6%. In these patients we obtained better results: 81.4% in the unilateral lesions, more than in the bilateral ones--72.7%; 82.5% in the renal artery trunk lesions, more than in the ostium ones--71.4%; 88.9% in the lesions of fibromuscular origin, more than in the aterosclerotic ones--75%; 84.4% in up to 55 years old patients, more than in older ones--71.4%. These differences were not significant. The results of renal angioplasty in renovascular hypertension suggest this type of intervention as an alternative treatment.

[Angioplasty of the arteries of the aorto-iliac region].

Percutaneous transluminal angioplasty (PTA) of the aorto-iliac arteries was performed in 92 patients with atherosclerotic lesions. The initial success was 87.8% and the late one was 69.4%. The late results were evaluated objectively in 58 patients, 36 of which were studied by angiography and the remaining by Doppler. There were 6.6% of complications, in 2.8% of which surgery was performed. There was no mortality. The good initial and late results and the low morbility suggest that PTA is a good revascularization procedure. The best results were obtained in symptomatic patients with a short and significant stenosis or occlusion.

[Angioplasty of the arteries of the femoro-popliteal region].

Percutaneous transluminal angioplasty (PTA) of the femuro-popliteal arteries with atherosclerotic lesions, was performed in 66 patients. There was an initial clinical success in 80.3% and a late one in 60.7%. Better results were obtained when there was good distal circulation, and the differences were significant. There was no mortality. These results show that PTA is an useful procedure in the treatment of obstructive lesions of femuro popliteal arteries.

Percutaneous sclerotherapy of varicocele.

Percutaneous sclerotherapy of varicocele was considered in 21 patients with left sided varicocele, 16 of whom had recurrences after left spermatic vein ligation in the past. Percutaneous sclerotherapy was possible in 17 patients (80.9%). There were no serious complications with venography or sclerotherapy, and the recurrence rate was 17.6%. Percutaneous sclerotherapy is therefore a simple, safe and effective treatment of testicular vein insufficiency.

Percutaneous placement of inferior vena cava filters.

Pulmonary embolism is a serious and difficult problem. Many approaches for the prevention of recurrent pulmonary embolism have been tried. Percutaneous placement of inferior vena cava filters is an easy, safe, available and well established procedure for the prevention of pulmonary embolism. The authors review the indications for use of IVC filters, and they review the main filters available in terms of ease of use, the physical characteristics, the technique of introduction, the efficacy and morbidity, and the potential complications associated with their use. Insertion of IVC filters by percutaneous approach was successfully performed in 6 patients with recurrent pulmonary embolism. Following the intervention procedure without complication there were no further pulmonary emboli.

Pulmonar vascular changes in the plain chest film of cardiac patients.

The correct interpretation of chest film on cardiac patients is very important. The most important feature is the radiographic appearance of the pulmonary vascularity. Four different patterns of pulmonary vascularity are considered: normal, decreased, increased and uneven. The different diseases associated with each type are mentioned. From the pulmonary vascular pattern one can deduct hemodynamic data which are important for the diagnosis, grade of severity and follow-up.

Internal iliac artery: embolization to control hemorrhage from pelvic neoplasms.

The control of the massive and often fatal hemorrhage from pelvic neoplasms is a major therapeutic problem. Transcatheter embolization of the internal iliac arteries was performed in 108 patients with uncontrollable hemorrhage due to pelvic neoplasms (urinary bladder in 50, uterus in 39, ovary in 16, and prostate in three). Complete control of the hemorrhage was achieved in 74 patients, partial control in 23, and no control in 11. Seventy patients experienced postembolization syndrome (nausea, vomiting, gluteal pain, and fever due to tissue necrosis), and three had transient acute tubular necrosis caused by the contrast medium. It is important for success that the embolization be bilateral and that the embolic agent used be a permanent one.
