  • EFFECTIVENESS COMPARISON BETWEEN ENDOVASCULAR RECANALIZATION AND OPEN SURGICAL REVASCULARIZATION TO TREAT PERIPHERAL PSEUDOANEURYSM

    Objective To compare the effectiveness, complications, and follow-up results between endovascular recanalization (EVR) and open surgical revascularization (OSR) in the treatment of peripheral pseudoaneurysm, so as to provide a reference for choosing a appropriate surgical procedure. Methods Clinical data of 62 cases of peripheral pseudoaneurysm between January 2001 and January 2012 were analyzed retrospectively. EVR was performed in 28 patients (EVR group) and OSR in 34 patients (OSR group). There was no significant difference in gender, age, cause of injury, tumor location, and diameter of tumor between 2 groups (P gt; 0.05). Results The operation time, blood loss, ICU monitoring time, and hospitalization time in EVR group were significantly shorter than those in OSR group (P lt; 0.05). In OSR group, 12 cases (35.29%) had early postoperative complications, including 2 deaths due to acute respiratory distress syndrome, 5 cases of pulmonary infection, 3 cases of wound infection, and 2 cases of deep vein thrombosis; in EVR group, 2 cases (7.14%) had early postoperative complications, including 1 case of hematoma at puncture site and 1 case of thrombosis in stent. There was significant difference in early postoperative complication incidence between 2 groups (χ2=6.691, P=0.008). The patients were followed up 12-39 months (mean, 26 months). In OSR and EVR groups after operation, the patency rates of the reconstructed vessels were 96.88% (31/32) and 92.86% (26/28) respectively at 12 months, showing no significant difference (χ2=0.014, P=0.905); the patency rates were 89.29% (25/28) and 84.00% (21/25) respectively at 24 months, showing no significant difference (χ2=0.322, P=0.570). Conclusion Compared with OSR, EVR is a minimally invasive, safe, and effective therapy for peripheral pseudoaneurysm with the advantages of less bleeding, shorter hospitalization time, and less complications. Long-term effectiveness still needs further observation, and patients have to take antiplatelet drugs for long time after EVR.

  • PRELIMINARY APPLICATION OF ANTERIOR UNCOVERTEBRAL JOINT RESECTION IN CERVICAL SPONDYLOTIC TERATMENT

    Objective To investigate the effect and safety of the anterior uncovertebral joint resection in treatment of cervical spondylotic myelopathy accompanied by radiculopathy. Methods From March 2002 toJuly 2004, 9 patients (5 males, 4 females; aged 38-66) with cervical spondylotic myelopathy accompanied by radiculopathy underwent the anterior uncovertebral joint resection and discectomy using the titanium cage implantation. There were 6 unilateral and 3 bilateral compressed nerve roots. Results During the follow-up for 3-16 months, CT scanning or X-ray films revealed thatall the patients improved with an enlargement of the intervertebral foramen, and MRI demonstrated that compression of the spinal cord and nerve roots vanished.Seven patients had a relief in the radicular pain although the other 2 still had a residual pain. All the patients improved to some extent in symptoms of myelopathy. No patient suffered vertebral artery injury during the operation. Conclusion The uncovertebral joint resection can directly decompressthe nerve roots. The key to avoidance of an injury to the vertebral artery is agood understanding of the regional anatomy and a good performance of the operation. 

  • The distribution and drug-resistance of pseudomonas aeruginosa in Fuwai Hospital of Chinese Academy of Medical Sciences from 2013 to 2016

    Objectives To retrospectively analyze the isolation rate and drug-resistance of pseudomonas aeruginosa in Fuwai Hospital of Chinese Academy of Medical Sciences from 2013 to 2016. Methods The specimens were collected and cultured. If the isolated bacteria were from the same part of the same patient, the first isolated strains were only counted. The isolated pathogens were identified and the drug-resistance were analyzed. Results A total of 1 404 pseudomonas aeruginosa were isolated. The majority of them were from postoperative recovery room of surgery department (62.1%) and ICU of internal medicine (22.3%). The specimen source were mainly from respiratory tract (75.7%), followed by blood (10.0%) and venous catheter (5.5%). The resistance rate of piperacillin and piperacillin/sulbactam to pseudomonas aeruginosa was 0.6% to 10.4%. The resistance rate of ceftazidime and cefepime was 0.3% to 11.7%. The resistance rate of imipenem and meropenem was 7.6% to 20.1%. The resistance rate of amikacin, gentamicin, and tobramycin was 0.3% to 3.2%. The resistance rate of ciprofloxacin and levofloxacin was 0.6% to 5.2%. Conclusions The isolates of pseudomonas aeruginosa are mainly from postoperative recovery room of surgery department and ICU of internal medicine . Imipenem and meropenem are not the best choices for pseudomonas aeruginosa infection. It has great value to combine piperacillin, piperacillin/sulbactam, ceftazidime and cefepime with aminoglycoside or quinolone antibiotics for the treatment of pseudomonas aeruginosa infection which will reduce drug resistance.

  • Treatment of cervical ossification of posterior longitudinal ligament with titanium alloy trabecular bone three-dimensional printed artificial vertebral body

    Objective To evaluate the effectiveness of using titanium alloy trabecular bone three-dimensional (3D) printed artificial vertebral body in treating cervical ossification of the posterior longitudinal ligament (OPLL). Methods A retrospective analysis was conducted on clinical data from 45 patients with cervical OPLL admitted between September 2019 and August 2021 and meeting the selection criteria. All patients underwent anterior cervical corpectomy and decompression, interbody bone graft fusion, and titanium plate internal fixation. During operation, 21 patients in the study group received titanium alloy trabecular bone 3D printed artificial vertebral bodies, while 24 patients in the control group received titanium cages. There was no significant difference in baseline data such as gender, age, disease duration, affected segments, or preoperative pain visual analogue scale (VAS) score, Japanese Orthopaedic Association (JOA) score, Neck Disability Index (NDI), vertebral height, and C2-7 Cobb angle (P>0.05). Operation time, intraoperative blood loss, and occurrence of complications were recorded for both groups. Preoperatively and at 3 and 12 months postoperatively, the functionality and symptom relief were assessed using JOA scores, VAS scores, and NDI evaluations. The vertebral height and C2-7 Cobb angle were detected by imaging examinations and the implant subsidence and intervertebral fusion were observed. Results The operation time and incidence of complications were significantly lower in the study group than in the control group (P<0.05), while the difference in intraoperative blood loss between the two groups was not significant (P>0.05). All patients were followed up 12-18 months, with the follow-up time of (14.28±4.34) months in the study group and (15.23±3.54) months in the control group, showing no significant difference (t=0.809, P=0.423). The JOA score, VAS score, and NDI of the two groups improved after operation, and further improved at 12 months compared to 3 months, with significant differences (P<0.05). At each time point, the study group exhibited significantly higher JOA scores and improvement rate compared to the control group (P<0.05); but there was no significantly difference in VAS score and NDI between the two groups (P>0.05). Imaging re-examination showed that the vertebral height and C2-7 Cobb angle of the two groups significantly increased at 3 and 12 months after operation (P<0.05), and there was no significant difference between 3 and 12 months after operation (P>0.05). At each time point, the vertebral height and C2-7 Cobb angle of the study group were significantly higher than those of the control group (P<0.05), and the implant subsidence rate was significantly lower than that of the control group (P<0.05). However, there was no significant difference in intervertebral fusion rate between the two groups (P>0.05). Conclusion Compared to traditional titanium cages, the use of titanium alloy trabecular bone 3D-printed artificial vertebral bodies for treating cervical OPLL results in shorter operative time, fewer postoperative complications, and lower implant subsidence rates, making it superior in vertebral reconstruction.
