[Percutaneous sacroplasty in sacral insufficiency fracture treatment].

Stress (insufficient) sacral bone fracture is a seriously painful disease with discussed and disunited therapy. Older women sufferig from osteoporosis create the main group in which this fracture occurs. Clinically, serious pain in sacral area is the most common symptome. This pain may last for a long time when treated conservatively and it can lead to pacient's immobilization with related comorbidity. In 2% of patients, neurological complications can be observed. Authors present summary of published studies and demonstrate an own case treated using percutaneous sacroplasty.

[Role of percutaneous vertebroplasty and kyphoplasty in the treatment of oncology disorders of the spine].

BACKGROUND: The aim of the study is to present results of a prospective uncontrolled clinical study. Percutaneous vertebroplasty or kyphoplasty are minimally invasive methods based on polymethylmethacrylate (PMMA) bone cement application into the damaged vertebra. This leads to decrease of the pain and vertebral body stabilisation. Oncology disorders of the spine are relatively common, having a wide alternative of various methods of treatment. Patients, according to their findings and indication criteria, are treated surgically or conservatively, oncological treatment is usually based on radiotherapy. Authors discuss the role of these invasive procedures in the treating algorithm of patients with spinal metasthases and multiple myeloma. METHODS AND RESULTS: From September 2003 to December 2005, 21 percutaneous vertebroplasties in 14 patients, mean age 68.7 (47-80) year, were performed in our department. During one treatment session 1-2 vertebrae (total of 21 vertebrae) in level Th9 - L5 were treated. Vertebroplasties and kyphoplasty were performed under fluoroscopy guidance. Transpedicular acces was used. Totally, 3 asymptomatic complications were proved. As first, a bone cement leaked paravertebrally during L5 body treatment, as second, a bone cement leaked into paravertebral veins, and as third, a bone cement leaked into the intervertebral space. Visual analog scale (VAS) was 8.9 points before procedure, 1.9 point 3 months after procedure and 2.6 points 6 months after procedure. We did not prove a symptomatic or total complication. CONCLUSIONS: According to our experience, percutaneous vertebroplasty is an effective alternative treatment of painful oncologic spine disease.

[Percutaneous vertebroplasty].

Percutaneous vertebroplasty is a therapeutic, interventional radiologic procedure originally developed in France by Galibert, Deramond et al. (1987). The technique consists of the percutaneous puncture of the affected vertebral body, followed by injection of bone cement into a vertebral body for the relief of pain, and the strengthening of the bone. The procedure was used initially to treat aggressive hemangiomas, but it then was extended to the treatment of osteolytic metastases, multiple myeloma and osteoporotic compression fractures refractory to medical therapy. In this article we review the current techniques, indications for this procedure, preoperative and postoperative evaluations.

[Long-term results after surgical treatment of head injuries].

It outflows from a survey of 174 cases operated during five years for skull injuries that the resulting state depends of preoperative level of consciousness. In injuries with the loss of consciousness, there is a close correlation between the type of motor-topain response and the resulting state. It was stated from the delay for up to 5 years after surgery that the independence from the day life has been achieved in 65% of injured patients which experienced preoperatively a mild loss of consciousness as they localized the pain stimulus or produced unintelligible sounds in response to pain. The similar condition has been achieved in only 14% cases of preoperatively deep loss of consciousness, which responded to pain or not with decerebrative extension, or unconsciously flexion of extremities. The resulting state is less dependent of operative diagnosis. Epidural hematomas show better results, where the independence of the day life has been achieved in 62% of cases. The majority of them was able to perform their previous working activities later on. In contrast, the worst results were achieved in association with brain contusions, where only 18% of injured patients sustained the independence of environs with no return to the previous work. Prognostically, the factor of age is the most important. In the age group over than 60 years, the mortality represented 58%, whereas in 20-40 years of age it was only 24%.

Vascular access monitoring evaluated from automated recirculation measurement.

Vascular access quality monitoring by means of vascular access blood flow (QVA) evaluated from automated thermodilutional measurement of recirculation with reverse needle position is described. This method provides significant advantages over conventional methods based on simple monitoring of pressures in the extracorporeal circuit and/or measurement of recirculation with normal needle position. AQVA evaluation protocol was developed and introduced into the system of primary nursing. The QVA values were found independent of the extracorporeal blood flow used during the recirculation measurement. QVA values from below 200 ml/min to over 2 l/min were seen. In general, lower values were found in diabetics compared to non-diabetics and in females compared to males. While blood flow below 600 ml/min is considered risky for synthetic vascular grafts, native AV-fistulae seem to remain stable and patent at a flow of 400 ml/min or even below. The method is able to detect erroneous needle placement in looped grafts, stenosis between needles, and is also well suited for effective evaluation of success/failure of interventions on access.
