A Study on the Effects of the Use of Propofol in Experimental Model Inferior Epigastric Island Flap on Ischemia-Reperfusion Injury.

Problems concerning vascular blood flow are the most frequently encountered ones after flap applications. The flap tissue starts to develop ischemia in patients with a vascular blood flow insufficiency. And reperfusion starts in those patients in whom the ischemia is temporary, triggering an ischemia-reperfusion injury depending on the duration of the ischemia. The aim of this study was to evaluate the effect of propofol, which is an anesthetic agent known to have an antioxidant effect and a free radical scavenging feature on the ischemia-reperfusion injury created on an experimental epigastric island flap.Thirty Sprague-Dawley rats were used in the study. The rats were divided into 3 groups of 10 rats each. Inferior epigastric artery-based abdominal flaps were prepared in all the groups. In group 1 (sham), the flap was elevated but no ischemia was applied. In groups 2 (control) and 3 (propofol), the flap was exposed to ischemia for 2 hours after it was elevated. All the rats were sacrificed and biochemical and histopathological assessments were made on the tissue samples taken on the 14th day. As a result of a comparison between the groups, the flap viability rates and the superoxide dismutase, total antioxidant capacity, and catalase values were found to be significantly higher (P < 0.001) in the propofol group while the malondialdehyde and total oxidative stress values were lower (P < 0.001). Based on the data obtained from the present study, the use of propofol was observed to have a protective effect against ischemia-reperfusion injuries in flap surgeries.

Opioids Inhibit Angiogenesis in a Chorioallantoic Membrane Model.

BACKGROUND: Angiogenesis is an important characteristic of cancer. Switching from the avascular phase to the vascular phase is a necessary process for tumor growth. Therefore, research in cancer treatment has focused on angiogenesis as a drug target. Despite the widespread use of opioids to treat pain in patients with cancer, little is known about the effect of these drugs on vascular endothelium and angiogenesis. OBJECTIVES: We aimed to investigate the efficacies of morphine, codeine, and tramadol in 3 different concentrations on angiogenesis in hens' eggs. STUDY DESIGN: This is a prospective, observational, controlled, in-vivo animal study. SETTING: Single academic medical center. METHODS: This study was conducted on the chorioallantoic membrane (CAM) of fertilized hens' eggs. The efficacies of morphine, codeine, and tramadol in 3 different concentrations were evaluated on angiogenesis in a total of 165 hens' eggs. RESULTS: Statistically significant differences were found between drug-free agarose used as a negative control and concentrations of morphine of 10 µM and 1 µM, a concentration of tramadol of 10 µM, and concentrations of codeine of 10 µM and 1 µM. Concentrations of morphine of 10 µM and 1 µM showed strong antiangiogenic effects. While codeine had strong antiangiogenic effects at high concentrations, at 0.1 µM it was shown to have weak antiangiogenic effects. However, tramadol at a concentration of 10 µM had only weak antiangiogenic effects. LIMITATIONS: This is just a CAM model study. CONCLUSION: In this study, we tested the effects of 3 different opioid drugs on angiogenesis in 3 different concentrations, and we observed that morphine was a good anti-angiogenic agent, but tramadol and codeine only had anti-angiogenic effects at high doses.Key Words: Morphine, codeine, tramadol, opioid, bevacizumab, chorioallantoic membrane (CAM), angiogenesis.

The use of thymoquinone in nephrotoxicity related to acetaminophen.

AIM: We aimed to investigate efficacy of intraperitoneally administered Thymoquinone (TQ) in acetaminophen (APAP) induced renal toxicity. MATERIAL AND METHOD: Forty Wistar Albino rats were randomly divided into 4 groups of ten rats each. Control group was untreated group while rats in TQ group were treated with single dose TQ. In APAP group rats were treated with single dose acetaminophen. In TQ + APAP group TQ and APAP were administered respectively. Rats were sacrificed at 24th hour; urea, creatinine and nitric oxide levels were measured also malondialdehyde activity were assessed in renal tissue specimens. Tissue damage scores were recorded in histopathological assessment. RESULTS: Urea and creatinine levels were found significantly higher in APAP group than control group (p < 0.003). Urea and creatinine levels in APAP + TQ treated group were significantly lower than APAP treated group (p < 0.01). Serum NO activity and tissue MDA levels were higher in APAP group than control group (p ≤ 0.002). In contrast to APAP treated group serum NO activity and tissue MDA levels were found significantly lower in TQ + APAP group (p ≤ 0.03). In APAP group significant histopathological change was found compared with control group (p ≤ 0.001) where there was no significant change between control and TQ treated groups (p > 0.05). In APAP group we found significantly higher tissue damage scores than control group (p ≤ 0.001). In APAP + TQ group lower tissue damage scores were found compared with APAP group (p ≤ 0.001) while higher scores were found compared with control group (p ≤ 0.001). CONCLUSION: We can conclude that TQ treatment has therapeutical effect in APAP induced nephrotoxicity in rats.

Therapeutic effects of thymoquinone in a model of neuropathic pain.

BACKGROUND: The goal of our study was to determine the therapeutic effects of thymoquinone in a dose-dependent manner in a model of neuropathic pain following an experimentally applied spinal cord injury (SCI). METHODS: Fifty female adult Wistar albino rats weighing between 220 and 260 g were included in the study and were divided into 5 groups as follows: Group S (sham), Group C (control), Group T100 (100 mg/kg thymoquinone), Group T200 (200 mg/kg thymoquinone), and Group T400 (400 mg/kg thymoquinone). To begin the experiment, SCI was applied to all groups (with the exception of the sham group) following a mechanical and heat-cold test. Two weeks later, the mechanical and heat-cold tests were repeated, and a single normal saline dose was given to the sham and control groups, whereas 3 varying doses of thymoquinone were given to the other groups. The mechanical and heat-cold tests were repeated at 30, 60, 120, and 180 minutes after receiving thymoquinone. Finally, the animals were put to death via the removal of intracardiac blood. The levels of nitric oxide, total oxidant status, total antioxidant status, paraoxonase, malondialdehyde, tumor necrosis factor-α, and interleukin-1ß were determined in all of the blood samples. RESULTS: The withdrawal threshold and withdrawal latency values recorded from the mechanical and heat-cold allodynia measurements for all 3 thymoquinone groups were higher than that of the control group at all time points (ie, 30, 60, 120, and 180 minutes). There were no differences in these results between the 3 thymoquinone groups. The paraoxonase and total antioxidant status serum levels of all 3 thymoquinone groups were higher than those of the control group, whereas total oxidant status, nitric oxide, malondialdehyde, interleuken-1ß, and tumor necrosis factor-α levels were lower in the 3 thymoquinone groups than in the control group. CONCLUSIONS: Thymoquinone is beneficial for decreasing experimental neuropathic pain following SCI. However, increasing the dose does not change the effect.

Magnetic resonance imaging in children under anesthesia: the relationship between the degree of information provided to parents and parents' anxiety scores.

BACKGROUND: We aimed to investigate the correlation between the anxiety scores of parents whose children are administered anesthesia for magnetic resonance imaging (MRI) and the level of information provided to them before the MRI. The study included 146 children and their parents. The demographic information of the children and their parents was recorded. The parents were divided into two groups. In Group I, the patient's medical history and physical exam findings were recorded on a standard consultation form by an anesthesiologist. In Group II, the parents were additionally provided with more detailed information on how the anesthesia would be administered and the drugs to be used and their side effects and complications. The anxiety scores of the parents were found to be lower in Group II. A higher level of education was associated with higher anxiety scores. Intergroup comparison detected lower anxiety scores for Group II parents whose education levels were up to high school. However, no change upon receiving detailed information was detected in the anxiety scores of parents with higher education levels. In conclusion, this may lower the anxiety scores in parents informed about details of anesthesia administration and may raise parents' sense of confidence in the doctor.

Thymoquinone treatment against acetaminophen-induced hepatotoxicity in rats.

AIM: In this study, we aimed to examine the efficacy of thymoquinone (TQ) treatment in acetaminophen-induced liver toxicity in rats. METHODS: Forty Wistar Albino rats were used for the study (four groups, with 10 rats for each group). Animals in the control group were not given any medication. In the thymoquinone (TQ) group, animals were given three times 5 mg/kg oral thymoquinone for every six hours, which equals to a total dose of 15 mg/kg. In the acetaminophen (APAP) group, animals were given APAP at a single dose of 500 mg/kg orally. In the APAP + TQ group, animals were given 500 mg/kg APAP orally followed by three doses of TQ at a 15 mg/kg total dose in an 18-h time interval. All animals were sacrificed at the 24th hour. Alanine amino transferase (ALT), aspartat amino transferase (AST), superoxide dismutase (SOD), oxidized glutathione (GSSG), glutathione peroxides (GSH-Px), and malondialdehyde (MDA) activities were measured in rat blood. Histopathological examination was also performed. RESULTS: Serum ALT, AST levels, GSSG, and SOD activity as well as the serum and tissue MDA levels were found to be higher in the APAP group than in the control group (p ≤ 0.001). Likewise, serum GSH-Px activity was found to be lower in the APAP group (p ≤ 0.001). In contrast, in the APAP + TQ group, serum ALT, AST levels, GSSG, SOD activity and the serum and tissue MDA levels were found to be lower compared to that of the APAP group. This difference was statistically significant (p ≤ 0.001). In the APAP + TQ group, the GSH-Px activity was found to be significantly higher compared to the APAP group (p < 0.05). In contrast to this finding, the GSH-Px activity in the APAP + TQ group was found to be lower than that of the control group (p ≤ 0.001). Histopathological analysis revealed significant liver necrosis and toxicity with a high dose of APAP where TQ treatment was related with significantly lower liver injury scores. CONCLUSION: TQ treatment may have an important therapeuthic effect via the upregulation of antioxidant systems in the APAP-induced liver hepatotoxicity in rats.

Protective role of caffeic acid phenethyl ester on serum cholinesterase inhibition by acute exposure to diazinon in rats.

AIM: To evaluate whether caffeic acid phenethyl ester (CAPE), a flavonoid-like natural compound plentifully found in beeswax, has a protective effect on diazinon-induced serum cholinesterase (ChE) inhibition in rats. MATERIALS AND METHODS: Animals were divided into 4 groups. The first animal group was not treated with any substance. The second animal group was orally given a 200 mg/kg body weight (bw) sublethal dose of diazinon. The third animal group was injected intraperitoneally with 2.84 mg (10 micromol)/kg bw of CAPE 1 day prior to administration of 200 mg/kg bw of diazinon orally. The fourth animal group was intraperitoneally injected with 2.84 mg (10 tmol)/kg bw of CAPE 30 min after 200 mg/kg bw of diazinon was orally administered. RESULTS: Analysis of the animal blood samples obtained 48 h after diazinon administration revealed that diazinon decreased serum ChE activity by 75%, while CAPE administration 24 h prior to and 30 min following diazinon application improved serum ChE activity by 25%-32% as compared to levels with diazinon administration only. In silico studies suggest that CAPE prevents diazinon from binding to butyryl ChE due to a higher binding affinity than that of diazinon. CONCLUSION: Our laboratory findings suggest that CAPE plays a protective role against butyryl ChE inhibition by diazinon.

Infraclavicular brachial plexus block in Wilson's disease.

Wilson's disease (WD) is characterized by progressive copper accumulation with hepatic and neurological impairment. Anesthesia and surgical practices may exacerbate WD and liver damage, and even cause life-threatening liver failure. Due to this existing liver damage, anesthetic management is important in WD cases in terms of drug choice, dose, and technique used. This study reports an emergency surgical procedure for trauma in a 24-year-old WD patient suffering the disease for 18 years. The operation was planned under infraclavicular brachial plexus block because of a right supracondiller/proximal humerus fracture. The selected type of anesthetic technique and agents in WD is specific. The pharmacokinetic changes in these cases are difficult to predict and require attention to drug choice and dose.

Inhalation anesthesia with sevoflurane during intravitreal bevacizumab injection in infants with retinopathy of prematurity.

BACKGROUND: To investigate the anesthetic management in premature infants with retinopathy of prematurity (ROP) treated with intravitreal bevacizumab (IVB) injections. METHODS: A retrospective chart review was performed for the patients with ROP who had IVB injection. Clinical characteristics, demographic variables, anesthetic medications, operation techniques, time intervals, and complications were recorded. RESULTS: Sixty-six eyes of 33 patients (23 males, 10 females) with type 1 ROP who were treated with IVB were included. A total of 66 anesthetic applications were performed. Mean gestational age at birth was 28.3 weeks (range 25-33). Mean birth weight was 1,300 g (range 600-1850). Serious ocular and systemic complications were not observed in any infant. CONCLUSION: Inhalation anesthesia with sevoflurane during IVB treatment in premature infants with ROP may be appropriate for anesthetic management.

Current attitudes of Turkish anesthesiologists to radiation exposure.

PURPOSE: The aim of this study was to investigate the attitudes of anesthesiologists to radiation exposure and current safety practice in Turkey. METHODS: The study enrolled anesthesiologists from all over Turkey, including all levels of academic degrees and all types of different institutions. Questionnaire forms were sent via e-mail to 505 anesthesiologists. The survey collected demographic data such as age, gender, position, and the institution at which the participant worked, and data about the frequency of radiation exposure during procedures and the participant's attitudes concerning radiation safety measures during these procedures. RESULTS: The questionnaire forms were delivered to 491 anesthesiologists, and 301 (61.3 %) of these were returned. Of these, 9 had not completed the questionnaire because of a lack of exposure to radiation. Among the remaining 292 personnel, the weekly frequencies of radiation exposure were more than five times (36.7 %), one to five times (50.3 %), and less than once (13 %) per week, respectively. Only a few anesthesiologists regularly wore a lead apron (30.11 %) and a thyroid shield (11.3 %) during procedures involving radiation exposure. CONCLUSIONS: This study demonstrated that nearly all anesthesiologists are regularly exposed to radiation and that few anesthesiologists in Turkey wear protective clothing, which is essential for radiation protection. Therefore, if it is not, increasing awareness about radiation protection should be an integral part of medical training and education.

The protective effect of dexmedetomidine on bupivacaine-induced sciatic nerve inflammation is mediated by mast cells.

PURPOSE: This study was designed to assess the correlation between the neuroprotective effect of dexmedetomidine and oxidative stress, neural inflammation and mast cell stability in rats with bupivacaine-induced sciatic nerve toxicity. METHODS: Forty adult Wistar Albino rats, eight rats per group, were used. Saline (0.3 ml of 0.9%), dexmedetomidine (20 µg/kg), 0.5% bupivacaine or 0.5% bupivacaine+dexmedetomidine (20 µg/kg) was injected into the sciatic nerve. A control group of rats received no injection. Fourteen days after injection, the sciatic nerves were harvested and total oxidant status, total anti-oxidant status, paraoxonase-1, galectin-3 and matrix metalloproteinase 2 and 9 levels were measured in the sciatic nerves. In addition, the presence and status of inflammation, edema, and mast cells were evaluated histopathologically. RESULTS: The combination of dexmedetomidine and bupivacaine alleviated oxidative stress. In addition, it decreased matrix metalloproteinase 9 and galectin-3 levels and increased matrix metalloproteinase 2 levels. Moreover, it stabilized recruited mast cells at the injury site; however, it did not significantly decrease inflammation or edema. CONCLUSION: Dexmedetomidine may ameliorate bupivacaine-induced neurotoxicity by modulating mast cell degranulation. The neuroprotective effect of dexmedetomidine may make it a suitable adjuvant agent to local anesthetics in peripheral nerve blocks.

The comparison of neuroprotective effects of intrathecal dexmedetomidine and metilprednisolone in spinal cord injury.

BACKGROUND: The purpose of this study is the investigation of the effects of intrathecally injected dexmedetomidine and methylprednisolone and their dominancy over one another in rats with generated Spinal Cord Injury (SCI). METHODS: 40, female, adult Wistar Albino rats weighing 220-260 g were included in the study. The rats were fixed with Intrathecal catheter (IT) and divided into four groups. All subjects were applied T7-10 laminectomy after catheter. Group S (n:10) was injected with IT 10 µL isotonic saline; Group C (n:10) with IT 10 µL isotonic saline after SCI; Group D (n:10) with IT one doze 10 µL of dexmedetomidine after SCI; Group M (n:10) IT one dose 10 µL of methylprednisolone. The subjects were sacrificed 72 h after this operation. The damaged area was removed biochemically and histopathologically examined. RESULTS: Antioxidant and inflammatory parameters searched for in all damages tissue were statistically different in all groups from group S. They were different in group M and group D than group C (p < 0.001). After the comparison of group D and group M, PON and IL6 values were higher in group D (p = 0.003, p = 0.035) while the other two biochemical parameters were similar in both groups (Table 1). After histopathologic trials, edemas, bleeding and necrosis were found less in group S while at the most in group C (p < 0.001). In group M and group D, however, they were higher than group S and lower than group C (p < 0.001). After the comparison of group D and group M, while there was no difference in terms of edema necrosis, the amount of bleeding was lower in group D (p < 0.001) (Table 2). CONCLUSIONS: It has been discovered that intrathecal use of dexmedetomidine caused neuroprotective effects similar to methylprednisolone.

The protective effects of dexmedetomidine on the liver and remote organs against hepatic ischemia reperfusion injury in rats.

AIM: To investigate the protective effects of dexmedetomidine against hepatic ischemia/reperfusion (IR) injury and hepatic IR induced remote organ injury. METHODS: Forty Wistar albino rats were divided into the following four groups: sham, dexmedetomidine, IR, and IR + dexmedetomidine. Hepatic ischemia was created by the Pringle maneuver for 30 min followed by a 30 min reperfusion period in the IR and IR + dexmedetomidine groups. The dexmedetomidine and IR + dexmedetomidine groups were administered dexmedetomidine (100 µg/kg, single dose) intraperitoneally after the anesthesia insult. Blood samples and hepatic, renal, and lung tissue specimens were obtained to measure serum and tissue total oxidative activity (TOA), total antioxidant capacity (TAC), paraoxonase (PON-1), and oxidative stress index (OSI) after 60 min in all groups. RESULTS: According to the biochemical analyses of the samples taken from the serum and the liver, lung, and kidney tissues, when comparing the sham group and the IR group, TOA and OSI values were higher in the IR group, while TAC and PON-1 values were lower (p < 0.05). It was observed that TOA and OSI values were significantly lower, while TAC and PON-1 values increased with dexmedetomidine treatment (p < 0.05). In addition, dexmedetomidine ameliorated hepatic histopathological changes inducing IR, but there were no significant histopathological changes in the remote organs. CONCLUSION: This study demonstrated that dexmedetomidine markedly reduced the oxidative stress in serum, liver, and remote organs induced by hepatic IR injury, and ameliorated the histopathological damage in the liver.

Radiation-free percutaneous nephrostomy performed on neonates, infants, and preschool-age children.

AIM: The aim of this study was to evaluate the effectiveness and safety of high-frequency linear probe ultrasonographic (US) guidance percutaneous nephrostomy (PN) in terms of diagnostic and therapeutic approach in preschool-age children with urological problems. MATERIALS AND METHODS: PN was performed on 40 kidneys in 33 patients (13 girls, 20 boys) aged 3 days - 7 years (mean 4.1 years). All procedures were performed with US guidance utilizing a Shimadzu SDU 2200 Xplus 5-10 mHz probe. Complete blood count, urinalysis, bladder urine culture, blood urea, and creatinine values were obtained before PN placement on the same day. Urine cultures were obtained by nephrostomy tube and compared to bladder urine culture. RESULTS: PN procedures were technically successful in 39 kidney units (97.5%). Two major complications were macroscopic hematuria requiring blood transfusions (1 case) and sepsis (1 case). Minor complications were displacement of the catheter (4), urinary tract infection (4), urine extravasation (1), early dislocation of the catheter (1). In three cases, the catheter was replaced. Analysis of bladder urine showed that 13 patients (39.4%) had positive cultures, but analysis of PN urine showed that 25 patients (78.1%) had positive cultures. CONCLUSIONS: PN is an easy, safe and efficient diagnostic and therapeutic procedure with few complications even in preschool-age children. The antibiotic regimen should be revised in order to avoid sepsis and urinary tract infection.

The forgotten ureteral stent in children: from diagnosis to treatment.

PURPOSE: We conducted a multicenter pediatric study of ureteral stents unintentionally left in situ. MATERIALS AND METHODS: A total of 22 patients with encrusted Double-J® ureteral stents unintentionally left in situ were treated at 4 centers between January 2007 and March 2012. Stone burdens were estimated using plain radiography and computerized tomography. Treatment decision was made based on clinical and radiological findings or stone burden. RESULTS: Nine girls and 13 boys with a mean age of 9.5 years (range 2 to 16) were analyzed. Mean indwelling time of ureteral stent was 21.7 months (range 6 to 60). Stents were inserted for the indication of urolithiasis (17 patients) and reconstructive urological intervention (5). In 2 patients stents had been placed bilaterally. Mean stent stone burden was 184 mm(2) on plain radiography and 247 mm(2) on computerized tomography, a difference that was statistically significant (p = 0.002). Shock wave lithotripsy was done in 6 cases. Endoscopic procedures were performed in all patients, including ureteroscopy in 8, simple stent removal in 7, endoscopic cystolithotripsy in 6, percutaneous nephrolithotomy in 5, retrograde intrarenal surgery in 3 and percutaneous cystolithotripsy in 2. Surgical removal of each stent required a mean of 1.5 interventions and a mean hospital stay of 4.4 days. CONCLUSIONS: At experienced centers combined endourological techniques can achieve successful and safe management of forgotten stents even in the pediatric age group. Thus, routine preprocedural tomography is a must in children with forgotten ureteral stents.

Retrograde intubation in the patient with cystic tumor located at the base of tongue.

Retrograde intubation is one of the methods used to maintain an airway in the event of a difficult intubation. Retrograde intubation has been successfully carried out on patient for whom intubation was not possible with a direct laryngoscope and fiber optic bronchoscope. The central venous catheter needle and guide wire are the materials that are the most practical to prepare and access for the retrograde intubation. To conclude, In conclusion, retrograde intubation may be good alternative to invasive airway management such as surgical tracheostomy for difficult or impossible intubations because it can be performed easily, quickly, and successfully.

[Efficacy of transforaminal lumbar epidural steroid injections in patients with lumbar radiculopathy]. / Lumbar radikülopatili hastalarda transforaminal lumbar epidural steroid enjeksiyonlarinin etkinligi.

OBJECTIVES: This study looks into the efficacy and safety of the transforaminal lumbar epidural steroid injection (TLESI) applied to patients with radiculopathy due to lumbar disk herniation. METHODS: The patients' files which were applied TLESI, were retrospectively scanned. Patients who did not respond to one-month conservative treatment and who were detected to have bulging or protruding lumbar disk herniation as a result of imaging methods were included in the study. All applications were performed with C-arm fluoroscopy under local anesthesia by outpatient method. In all cases, a mix of 80 mg triamsinolone and 0.25% bupivacaine, was transforaminally injected to the anterior epidural area. Initial VAS pain scores were compared with the values of the 1, 3 and 6th months after the application. Patient satisfaction was determined through scoring. Furthermore, early and late term complications were collected for evaluation. RESULTS: A total of 222 patients were administered TLESI 460 times (average: 2.1, repeat interval: 1-6 times). The applications were carried out most frequently at the levels of L4-L5 and L5-S1. While the initial VAS score average was 8.2±0.7, after TLESI, it was 5.0±1.6, 4.8±1.5 and 5.1±1.5 in the 1, 3 and 6th months, respectively. 63.9% of the patients (n=142) defined the treatment as 'good and excellent'. No major complications were experienced and the overall minor complication rate was 11.1%. CONCLUSION: It was seen that TLESI was an efficient and safe method in the short and medium term.

[Our percutaneous vertebroplasty applications in vertebral compression fractures]. / Vertebra kompresyon kiriklarinda perkütan vertebroplasti uygulamalarimiz.

OBJECTIVES: We aimed to investigate the effectiveness and complications of the percutaneous vertebroplasty (PVP) applications in vertebral compression fractures. METHODS: Our study was carried out as a retrospective study in which PVP was conducted on patients with vertebral compression fractures due to benign or malignant causes between October 2006 and December 2009. The patients' pain was evaluated on a visual analog scale (VAS). In addition, the amount of cement injected, whether or not any leakage from the vertebrae corpus was seen, and any complications resulting from the application during or after the operation were recorded. The age and gender of the patients, duration of pain, number and location of fractured vertebrae, and the duration of follow-up were also collected for evaluation. RESULTS: A total of 15 patients were included in the assessment. Of the patients, 13 were female, and the mean age was 69.5±8.5 years. A total of 19 PVPs were applied to the 15 patients. While initial VAS scores were 7.9±1.6, at the end of an average of 10.3±3.8 (range: 4-18) months of follow-up, VAS scores had fallen to 2.6±2.7. 80% of the patients reported at least a 50% reduction in pain scores compared to initial scores, and 86.7% of them reported at least a 2-point decrease in VAS scores. In three patients, leakage of cement into the intervertebral disc occurred. CONCLUSION: PVP may be used successfully in symptomatic vertebral compression fractures not responding to medical treatment, with a low rate of complications.
