  • Progress of perioperative pain management in patients with lower limb vascular diseases

    ObjectiveTo summarize the progress of perioperative pain management in patients with lower limb vascular diseases. MethodRetrieved the literature about pain management in patients with lower limb vascular diseases both at home and abroad in recent years and reviewed the literature. ResultsLower limb vascular diseases were very common in elderly patients. Whether it was limb ischemic pain or surgery-related pain, it often increased the stress response and activation of the autonomic system, which was not conducive to the recovery of the disease. Good analgesic management was important for these patients. Perioperative pain management could be performed by intravenous analgesics, oral analgesics, local anesthesia, neuraxial anesthesia and peripheral nerve block. Acute and chronic pain should be actively managed during perioperative period. Pre-emptive analgesic strategies could be implemented in patients with severe peripheral vascular disease. ConclusionsGood perioperative analgesia management is necessary. Pain management which employes one or more analgesic methods is important in maximizing pain relief, function, and quality of life for this patient group.

  • Progress of gene research for chronic venous ulcer

    ObjectiveTo understand progress of gene research for chronic venous ulcer (CVU) so as to seek for the best treatment strategy for it.MethodThe literatures about studies on gene polymorphism and variability that leaded to the occurrence and development of CVU in recent years were reviewed and analyzed.ResultsThe CVU was mainly caused by the chronic venous insufficiency (CVI). Many changes in the gene expression had been found in the curable CVU and incurable CVU. The expressions of regulated inflammatory genes, encoding extracellular peptide genes, and encoding different cellular pathways genes in the incurable CVU patients had remarkable differences as compared with the healthy individuals. Although there were more studies on incurable CVU than curable CVU, it was still unable to accurately predict the healing time of CVU. At the same time, genome-wide associations study had not been performed to find single nucleotide polymorphism related to the risk of CVU.ConclusionsAlthough CVU is mainly caused by CVI, not all patients with CVI have ulcer. At present, parts of risk factors of CVU have been known, such as age, iliofemoral vein embolism, deep vein insufficiency, hypertension, obesity, and so on. However, there are fewer studies on heredity, so it is necessary to strengthen its research. Gene expression and gene polymorphism have increasingly become focus of research on causes of chronic inflammation. Genome-wide association study is a gold standard of complex disease genetics, so it is neccessary to further search so as to better understand genetic basis and genetic background of CVU and find the best treatment strategy for improving ulcer healing.

  • Diagnosis, treatment and prevention of venous thromboembolism after discharge of COVID-19 infection

    Inpatients after COVID-19 infection, especially those admitted to intensive care unit (ICU), may encounter a series of coagulation dysfunction, which may lead to thrombosis, such as pulmonary embolism (PE), deep vein thrombosis (DVT) or arterial thrombosis (AT). Although there are many literatures on the incidence rate, prevention and treatment of venous thromboembolism (VTE) in hospitalized patients with COVID-19 infection, there are few data on the symptomatic and subclinical incidence rate of VTE after COVID-19 infection discharge. Therefore, there are no specific recommendations or guidelines for the prevention of VTE after discharge from hospital due to COVID-19 infection, and the current guidelines are controversial. In this study, we reviewed and summarized the existing literature on the incidence rate, prevention, diagnosis and treatment of venous thromboembolism in patients with COVID-19 infection, in order to provide guidance for VTE prevention in patients with COVID-19 infection after discharge.

  • Analysis of litigation cases of medical injury liability disputes related to inferior vena cava filters

    Objective To identify and analyze all medical injury liability disputes lawsuits pertaining to inferior vena cava filters (IVCF) in “Lexis®China” database, the causes and outcomes of litigation of the cases were clarified with a view, and to provide suggestions for preventing potential medical patient dispute lawsuits and improving the clinical diagnosis and treatment level of doctors. Method The term “inferior vena cava filter” was searched in Lexis®China, and spanning from 2011-01-01 to 2022-12-31. Results A total of 221 cases of medical injury liability disputes were found, after screening and exclusion, a total of 179 relevant cases were included in this study for analysis. All first instance lawsuits were brought by patients against hospitals and had a high rate of compensation awarded (91.6%). Forty four cases were entered second instance litigation, and the proportion of maintaining the original judgment was high (68.2%). The main content involving the modification of the judgment was to increase the compensation amount (85.7%). In the 14 lawsuits related to the failure to place IVCF by the medical authority, the litigation points were all disputes arising from the hospital’s improper diagnosis and treatment of VTE patients, which led to the failure to place IVCF, with the highest proportion (92.3%) of improper diagnosis and treatment of pulmonary embolism (PE). For PE and deep vein thrombosis patients with clear indications for IVCF implantation but not placed, leading to litigation, the hospital bore different liability for compensation (18%–100%) depending on the fault factors of the hospital’s negligence in diagnosis and treatment. The hospital could also be held responsible for inadequate informed disclosure to affect patient judgment (23.1%). In 165 lawsuits related to the placement of IVCF, the vast majority of IVCF implants were for the diagnosis and treatment of VTE in patients (73.9%). However, such unplanned operations caused additional injuries and expenses to patients, and VTE occurred most frequently during hospitalization (76.2%). This type of embolism was most commonly secondary to fracture incision and fixation surgery (31.2%), and the average liability of hospitals for compensation varied due to different secondary factors. The occurrence of intraoperative and postoperative complications related to IVCF implantation could also lead to litigation (18.8%), and the proportion of dead patients in litigation was relatively high (32.3%). The most common complication leading to litigation was PE recurrence or exacerbation (22.5%), while intraoperative complications were vascular injury during interventional procedures (2/3). The overall trend of IVCF-related lawsuits reserves between 2011 and 2020 showed an overall upward trend, reaching a peak of 37 cases in 2020; the average amount of damages exceeded 100 000 yuan per case in 10 of the 12 years included in the statistics. Conclusions In China’s IVCF-related medical liability lawsuits, patients most often sue their doctors, who are often sued for failure to insert a filter due to untimely diagnosis and treatment of VTE, inadequate notification of informed consent for IVCF insertion, unplanned IVCF insertion due to the presence of VTE and IVCF-related complications, and the outcome is often unfavourable to the doctors. In addition, the number of IVCF related lawsuits and hospital compensation amounts have remained high in recent years.

  • Research progress of biomarkers related to deep vein thrombosis

    ObjectiveTo summarize the new biomarkers of deep venous thrombosis (DVT) and their research progress, so as to provide new ideas for the prevention, diagnosis and treatment of DVT. MethodThe literature about biomarkers of DVT in recent 5 years was reviewed and summarized. ResultsAccording to the results of literature review, a variety of common DVT biomarkers such as serum microrna, fibrin monomer, neutrophil capture net, and E-selectin were sorted out, but most of them had not been used in clinical DVT management. At present, the clinical diagnosis of DVT required the combination of positive D-dimer test and positive imaging examination, and there was no single biomarker for the diagnosis of DVT. ConclusionsBiomarkers are valuable in the diagnosis and treatment of DVT, but their sensitivity and specificity need to be optimized. Therefore, finding biomarkers with more diagnostic value is one of the future directions. At the same time, we also can consider fully combined with a variety of existing biomarkers, to improve the efficiency to the diagnosis of DVT.

  • The Surgical Management of Primary Peritoneal Tumor Involving Iliac Vessels

    Objective To discuss the surgical management in resection of primary peritoneal tumors involving iliac vessels. Methods The clinical data of 124 patients with primary peritoneal tumors involving iliac vessels, that underwent surgical procedures from December 2006 to December 2011 were analyzed retrospectively. There were 68 menand 56 women with an age raging from 16-72 years old (mean 44 years old). Results All patients underwent operative treatment. Fifty-two patients with tumors infiltrating or surrounding the major illiac vessels, 72 patients with tumors compressing the iliac vessels. Primary peritoneal tumors involving iliac vessels were completely resected in 90 patients, were incompletely resected in 31 patients, and were palliatively resected in 3 patients. Resectoin of primary peritoneal tumors and iliac vessel reconstruction were performed in 42 patients with tumors infiltrating or surrounding the major illiac vessels. There was no death during perioperative period. There were complications in 2 patients, that including urinary fistula in 1 patient and fat liquefaction of incision in 1 patient. Complications were not found in the rest of the patients. All patients were followed-up from 12-24 months (mean 16 months). Thirty-eight patients relapsed locally in 90 patients with tumor completely resected. Nine patients died in those tumor incompletely resected(6 patients died because of recurrence, 3 patients died because of cadiovasuclar and cerebrovascular accidents). Three patients follwing palliative resected were dead during the follow-up period (3 patients died because of recurrence). Among the 42 patients underwent the procedure of iliac vessels, recurrence occured in 3 patients without involving iliac vessels, 1 patient relapsed involving inferior vena cava (IVC) which resulted in IVC obstruction and deep venous thrombosis following 7 months after operation. Recurrence occured in 2 patients involving common iliac veins following 8 months after operation. Venous thrombus of common iliac vein graft occured in 1 patientin in 10 months after operation. Conclusion Resection completely and involved iliac vessel reconstruction would reduce recurrence of tumor and promote long term survival in patients with primary peritoneal tumors involving iliac vessels
