[Percutaneous vertebroplasty in the treatment of osteoporotic vertebral compression fractures: first short term results].

OBJECTIVE: To describe the technique of percutaneous vertebroplasty and the short-term results in patients with symptomatic, osteoporotic vertebral compression fractures. DESIGN: Prospective follow-up study. METHOD: In a pilot-study to evaluate the short-term safety and effectiveness of percutaneous vertebroplasty, 18 consecutive patients with a total of 33 osteoporotic thoracic or lumbar vertebral compression fractures were treated from October 2001 to June 2002 with a follow-up of 3-6 months. The indication for treatment was a symptomatic, therapy-resistant osteoporotic vertebral compression fracture. Percutaneous vertebroplasty was performed under radiographic control, after previous intraossal venography, using bone cement mixed with barium sulphate. Post-procedural follow-up consisted of radiological evaluation with conventional thoracolumbar X-rays and MRI scans, and interviews of the patients. RESULTS: Percutaneous vertebroplasty was technically successful in 31 of 33 vertebral fractures (94%), and in 16 of 18 patients (89%). One patient with extreme venous contrast leakage could not be treated. Sixteen patients had less or no pain after treatment. One patient retained thoracolumbar back pain after inadequate cementations and refused further treatment. None of the patients reported aggravation of symptoms following the procedure. Contrast leakage was absent in 18 vertebrae. In 8 vertebrae there was contrast leakage to paravertebral veins. In three of these cases the leakage was so severe that embolisation was performed, with success in one case. In 13 vertebrae, cement leakage to intervertebral and paravertebral spaces and pedicular cement spurs were seen, without clinical consequences. Immediately after the procedure and during follow-up there were no clinically relevant complications. CONCLUSION: Percutaneous vertebroplasty was a technically feasible treatment in these patients with symptomatic, therapy-resistant, osteoporotic vertebral fractures. The first short-term results were comparable with results in the literature. A prospective randomised intervention study will be needed to compare percutaneous vertebroplasty with optimal conservative treatment.

[Embolization as treatment for symptomatic uterus myomata].

Selective percutaneous embolisation of the uterine arteries was carried out on three women with hypermenorrhea caused by uterine myomata. Two of the patients experienced resumption of the normal menstrual pattern. In the first case the myoma became 30% smaller and in the second case, the fibroid was expelled into the vagina six months later. The third patient suffered a fever one week after the treatment due to an infected necrotic myoma, after which a hysterectomy was carried out. The embolisation of myomata can offer an alternative to medicinal treatment, myomectomy or hysterectomy. The advantages of embolisation compared to a hysterectomy are a shorter hospital admission time, quick recovery after the procedure and retention of the uterus.

[Embolization as treatment for postpartum hemorrhage].

A 33-year-old woman suffered from an early postpartum bleeding (15 hours after delivery) and a 29-year-old patient from a late one (nine days postpartum). Both women were treated with conservative methods including curettage and surgical evacuation of the haematoma in one case. However, blood loss didn't stop. Instead of hysterectomy it was decided to embolize the appropriate cervicouterine branch of the A. uterina in these young women, which appeared to be effective. In case of non-effective treatment of postpartum bleeding, hysterectomy is not the only remaining therapy. Gynaecologists and radiologists together may consider embolization therapy. This has proved to be a minimally invasive and successful treatment. Unlike hysterectomy, the uterus will be preserved, making an additional pregnancy possible.

Stenting in the femoral superficial artery: an overview.

Stenting in the superficial femoral artery is still a controversial treatment in case of occlusive disease. Although the results of percutaneous treatment especially in the Hunter canal region are moderate, balloon angioplasty is nowadays an established technique. Many investigators tried to improve their results with additional stenting of the superficial femoral arteries after inappropriate results of balloon angioplasty and/or stenting. Although the figures of results after stenting are not consistent in literature even when using stent graft material I still feel that especially in the superficial femoral artery stenting procedures should not be performed on a routine basis. The main issue in stent failure is the extensive intima hyperplasia. Many investigators are working on this problem but as long as no real solution is available I feel that we have to act reluctantly in treating superficial femoral arteries with stents.

False aneurysm of the right internal mammary artery.

False aneurysms of the internal mammary artery are extremely rare. A case of false aneurysm of a branch of the right internal mammary artery after median sternotomy is reported. A large right-sided mediastinal mass was seen on the thoracic radiogram. A false aneurysm was suspected on CT-scan and confirmed by angiography. In the same setting percutaneous embolization was performed.

Haemorrhage due to laceration of an aberrant inferior epigastric artery during femoropopliteal PTA in an obese patient; a rare complication of a high antegrade femoral puncture.

Haemorrhage due to laceration of the proximal inferior epigastric artery during femoro-popliteal PTA in an obese 79-year-old woman is reported as a rare complication of a high antegrade femoral puncture. The post procedural haemorrhage was caused by a high antegrade puncture lacerating a low overriding inferior epigastric artery.

Embolization therapy in haemoptysis.

Massive haemoptysis is a serious clinical condition to be treated with transcatheter embolotherapy of bronchial and/or other systemic arteries to the lungs. Lung bleeding frequently originates from sites other than bronchials alone. It is important to consider the extensive collateral network between bronchial, intercostal and pulmonary arteries and veins. Between 1980 and 1991, 70 patients were embolized. Fifty individuals were controlled with a mean follow-up time of 62 months. Most frequently pathology was seen in vessels originating from the right upper middle lung region. The embolization agents we used were IBC, NIBC, dura mater particles, and Ivalon+IBC. Recurrent bleeding was noticed in five patients, but not from embolized vessels. No major complications were encountered. Selective embolotherapy with tissue adhesives resulted in good short-term (90%) and long-term (100%) results. In 10% of cases, two or more embolization sessions were needed to cure the patient of haemoptysis.

Low-dose streptokinase in the treatment of arterial graft occlusions.

During the past 24 months, 19 infrainguinal bypass graft occlusions occurring in 17 patients were treated with local infusions of streptokinase. The treated grafts included three venous femorocrural grafts and four venous and 13 Goretex femoropopliteal grafts. Infusion managed to restore flow completely in 10 grafts. Partial clot lysis occurred in three and no lysis in six grafts. All successful recanalisations occurred within 120 hours of the initiation of thrombolytic therapy. Despite three major complications and the development of two minor haematomas, with an overall success rate of 55% our results support the use of streptokinase in the management of occluded bypass grafts.

Deep venous thrombosis of the leg: US findings.

In a prospective study, 121 consecutive patients with a clinical diagnosis of deep venous thrombosis of the leg were examined with real-time ultrasonography. The findings were correlated with the results of venography. The common femoral vein and the popliteal vein were evaluated for intraluminal echoes and compressibility, and the common femoral vein was also evaluated for an increase in diameter in response to the Valsalva maneuver. The superficial femoral vein and the calf veins were not evaluated. The results indicate that compressibility of the common femoral and popliteal veins is the best indication of deep venous thrombosis, with a sensitivity of 96% and a specificity of 97%. The accuracy of detection was not improved by including data from thrombus visualization or the response of the common femoral vein to the Valsalva maneuver.
