Objective To investigate the impact of different modes of cardiopulmonary bypass （CPB） and cerebral perfusion on cerebral protection in patients with Stanford type A aortic dissection （AD）. Methods Clinical data of 117 patients with Stanford type A AD who underwent surgical therapy from April 2007 to March 2012 in the First Affiliated Hospital of Harbin Medical University were retrospectively analyzed. All the patients were divided into 3 groups according to different modes of CPB and cerebral perfusion they received. In group 1，45 patients received CPB perfusion through the femoral artery and unilateral or bilateral antegrade selective cerebral perfusion （ASCP） after circulatory arrest. In group 2，38 patients received CPB perfusion through the subclavian artery or innominate artery and unilateral or bilateral ASCP after circulatory arrest. In group 3，34 patients received antegrade and retrograde CPB perfusion through both subclavian artery or innominate artery and femoral artery，and unilateral or bilateral ASCP after circulatory arrest. Postoperative occurrence of transient neurological dysfunction （TND），permanent neurological dysfunction （PND） and influential factors were compared between the 3 groups. Results Incidence of postoperative cerebral complications of group 1 was significantly higher than those of group 2 and 3 （37.77% vs. 13.16% vs. 14.71%，P ＜0.05）. During CPB，cooling time of group 3 was significantly shorter than those of group 1 and 2 （35.56±4.35 vs. 40.00±5.63 and 39.58±6.03，P ＜0.05）. There was no statisticaldifference in other influential factors among the 3 groups （P ＞0.05）. Conclusion Antegrade and retrograde CPB perfusionin combination with ASCP has a smooth and quicker cooling rate，may provide better protection for the spinal cord，kidney and intraperitoneal organs and especially decrease the incidence of postoperative cerebral complications，therefore is proved current best method for organ protection.
ObjectiveTo explore the combined application of neutrophil to lymphocyte ratio (NLR) and systemic immune inflammation index (SII) on the prognosis of hepatitis B-related hepatocellular carcinoma after resection.MethodsRetrospectively collected data of 180 patients with hepatitis B-related hepatocellular carcinoma who were hospitalized in the Department of Infectious Diseases and Hepatobiliary Surgery of the Affiliated Hospital of Southwest Medical University and received surgical treatment from January 2013 to December 2019, including general information, laboratory examination and abdominal CT or MRI results. NLR and SII values were measured at one week before operation, and their critical values of NLR and SII were determined by ROC curve analysis. Univariate and multivariate analysis were performed to determine the risk factors to predict the survival status of patients with hepatitis B-related hepatocellular carcinoma after hepatectomy.ResultsUnivariate analysis showed that AFP, platelets, TNM staging, portal vein tumor thrombus, tumor differentiation, NLR, SII, and NLR+SII combined score were significantly correlated with the prognosis of patients with hepatitis B-related hepatocellular carcinoma (P<0.05). Multivariate analysis showed that PLT [HR=1.791, 95%CI (1.124, 2.854), P=0.014], NLR [HR=4.289, 95%CI (2.571, 7.156), P<0.001], SII [HR=5.317, 95%CI (3.016, 9.374), P<0.001], and NLR+SII combined score [HR=7.901, 95%CI (4.124, 15.138), P<0.001] were independently correlated with the survival of patients with hepatitis B-related hepatocellular carcinoma.ConclusionsThe preoperative NLR+SII combined score can be used to evaluate the postoperative prognosis of patients with hepatitis B-related hepatocellular carcinoma. The higher the score, the lower the postoperative survival rate.
ObjectiveTo investigate the clinical efficacy of AngioJet thrombectomy combined with iliac vein stenting for patients diagnosed with acute lower extremity deep venous thrombosis (DVT) with iliac vein compression. MethodsBetween January 2021 and October 2023, a total of 64 patients with acute lower extremity DVT which performed AngioJet thrombectomy combined with iliac vein stenting in Weifang People’s Hospital were retrospectively analyzed. The changes of clinical symptoms, signs, and thrombus burden between pre- and postsurgically were observed. The venous patency score, thigh circumference, calf circumference, venous clinical severity score (VCSS), and chronicvenous insufficienc questionnaire-14item (CIVIQ-14) scores were recorded pre- and postsurgically, and the patency of stent was statistically evaluated by a comprehensive assessment of the postoperative 12-month angiography. ResultsOperative success was achieved in all the 64 patients. The aspiration time was 300－480 s [(313±32) s], and the operative time was 80－120 min [ (97±21.5) min]. No complications such as bleeding and hematoma occurred after operation. The hospitalization time was 5－12 d [ (7.5±2.8) d]. After operation, the patency score of vein and stent and the difference of thigh circumference diameter decreased or reduced, and the difference were statistically significant (P<0.001). The score of VCSS and CIVIQ-14 decreased or increased significantly after the operation, and the difference were statistically significant (P<0.05). Color Doppler ultrasound was performed at the first, third and sixth months after operation, and anterograde venography of lower limbs was performed at at the 12th month. Only one patient had thrombosis recurrence at one month after operation, and finally developed into post-thrombosis syndrome of deep veins of lower limbs after anticoagulant conservative treatment. The veins and stents of the rest patients were unobstructed. ConclusionAngioJet thrombectomy, together with iliac vein stenting, could effectively expedited clot removal, reduced limb swelling; prevented post-thrombotic syndrome recurrence and significantly improved quality of life for patients with acute lower extremity deep venous thrombosis.
ObjectiveTo explorethe method and effectivenessofarthroscopically assisted treatmentof rotator cuff injury. MethodsBetween November 2009 and March 2011, 27 patients with rotator cuff injury were treated. There were 17 males and 10 females with a mean age of 43.6 years (range, 29-66 years). The disease duration was1 to 36 months (mean, 27months). The location was theleft shoulder in 11 cases and theright shoulder in 16 cases. Of them, 12 cases had a history of trauma and 15 caseshad no obvious predisposing causes. All patients had limitation of shoulder flexionandabduction. Anteroposterior and lateral X-ray films of the shoulder and the out-let X-ray films of the supraspinous muscle were taken. According to the acromion classification of Bigliani, there were 5 cases of type I, 13 cases of type II, and 9 cases of type III. MRI images showed all patients had rupture of the rotator cuff. The examination of shoulder arthroscope showed complete rupture of the supraspinatus muscle in 27 cases and acromion impingement in 23 cases. The patients without impingement underwent tear debridement, and the patients with impingement underwent acromioplasty and resection of subacromial bursa after tear debridement. The 3-4 cm incision was made with arthroscopically assisted positioning, and the metal suture anchorwas placed on the greater tubercle of humerus to repair rotator cuff. ResultsAll incisions healed primarily. All patients were followed up 13-27 months (mean, 19 months). No infection, loosening of internal fixation, and rotator cuffre-tearoccurred. Pain was relieved and the results was satisfactory after operation. The shoulder range of motion (ROM) at last follow-up was significantly improved when compared with preoperative ROM (P lt; 0.05). The visual analogue scale (VAS) score was significantly improved from 8.0 ± 1.8 at preoperation to 1.6 ± 0.7 at 2 weeks after operation and 0.8 ± 0.7 at last follow-up (Plt; 0.05); the University of California Los Angeles (UCLA) score of shoulder was significantly increased from 18.8 ± 6.6 at preoperation to 32.2 ± 3.3at 3months after operation and 33.6 ± 2.1 at last follow-up (P lt; 0.05). Conclusion The effectivenessofarthroscopically assisted treatmentof rotator cuff injury is satisfactory. However, long-termeffectiveness needs furtherfollow-up observation.
