Objective To investigate the application and clinical efficacy of orthotopic autologous renal transplantation combined with inferior vena cava (IVC) resection and reconstruction in retroperitoneal tumor. Methods The clinical data of a patient with complex retroperitoneal tumor was analyzed retrospectively. Abdominal CT examination showed that the tumor originated from IVC and invaded the retrohepatic IVC and bilateral renal vein trunks. Intraoperative ultrasound exploration revealed mechanized thrombosis in the IVC and bilateral renal vein trunks. After blocking the left renal vein, no significant hemodynamic changes were seen before and after intraoperative ultrasound exploration and contrast-enhanced ultrasound. Results After complete removal of the left renal vein and suture of the severed end, the right renal vein was successfully reconstructed with an orthotopic autologous right kidney graft combined with IVC resection after removal of the mechanized thrombus. The patient recovered well after surgery, and a repeat CT showed that the reconstructed artificial IVC was patent, and the color Doppler ultrasonography of both kidneys showed good perfusion and no obstruction of return. The patient was given oral rivaroxaban anticoagulant therapy after operation, and discharged at 19 days after operation. The postoperative pathological findings suggested inferior vena cava smooth muscle sarcoma. Conclusion Orthotopic autologous renal transplantation combined with IVC resection and reconstruction for complex retroperitoneal tumor is safe and feasible, and the left renal vein can be ligated and dissected intraoperatively, but a comprehensive evaluation with intraoperative ultrasound (imaging) is required.
Objective To analyze the quantitative relationship between respiratory effort and inferior vena cava (IVC) diameter variability in healthy adults, and explore the effects of respiratory effort on the fluid responsiveness with IVC diameter variability. Methods From October 2022 to May 2023, a cross-sectional study was conducted in healthy young subjects who met the criteria. Respiratory effort was evaluated by using portable pulmonary function to measure the subjects’ inspiratory conditions in three states (quiet breathing, moderate inspiration, and maximal inspiration). At the same time, the IVC internal diameter was measured by bedside ultrasound and the IVC diameter variability was calculated. The correlation between inspiratory volume and IVC diameter variation was analyzed, and the receiver operator characteristic (ROC) curve was drawn. The sensitivity and specificity of fluid responsiveness induced by inspiratory effort were predicted according to the area under the ROC curve (AUC). Results A total of 95 subjects were screened, aged 27.13±5.77 years, of whom 30 (32%) subjects were males. During quiet breathing, 41.1% of subjects had IVC inner diameter variation ≥50%. For moderate inspiration, it was 68.4%. At maximum inspiration, this proportion is more than 85%. Inspiratory volume was moderately positively correlated with IVC diameter variation, and the correlation coefficient r=0.45. With the IVC diameter variation ≥50% as the positive criterion for fluid responsiveness, the AUC of fluid responsiveness induced by inspiratory effort was 0.73 (95% confidence interval 0.67 - 0.78, P<0.001), and the inspiratory volume threshold was 13 mL/kg ideal body weight when the maximum Youden index was 0.41. That is, moderate force breathing can induce fluid responsiveness, with sensitivity of 79.57% and specificity of 61.62%. Conclusion The degree of respiratory effort significantly affects the IVC inner diameter variation, and there may be false positives in the evaluation of fluid responsiveness according to IVC inner diameter variation in the case of spontaneous breathing.
ObjectiveTo understand the characteristics of patients who have undergone the removal of the inferior vena cava (IVC) filter, so as to provide a reference for optimizing the clinical application strategy of IVC filters. MethodThe demographic and clinical characteristics of patients underwent IVC filter removal in the Division of Vascular Surgery, Department of General Surgery, West China Hospital, Sichuan University from December 2016 to December 2023 were retrospectively collected. ResultsA total of 102 patients were enrolled, including 48 (47.1%) males and 54 (52.9%) females. The age of the patients was (46.75±16.72) years old, and 75 (73.5%) patients were aged between 20 and 59 years old. The proportion of patients underwent retrieval after IVC filter placement due to combined central deep vein thrombosis was highest, accounting for 48.0% (49/102). Of the 102 patients, 72 (70.6%) patients underwent IVC filter removal within 90 d and 6 (5.9%) patients underwent IVC filter removal after more than one year. The median duration of filter placement for all patients was 35 d (ranging from 5 to 7 300 d). The filter was removed via interventional method in 92 (90.8%) patients and via open surgery in 10 (9.8%) patients. The endovascular retrieval failed in one of 92 patients and then the follow-up observation was selected. Compared with the interventional treatment, the patients who had the filter removal by open surgery had a longer placement time of the filter in the IVC (median: 136.5 d vs. 32.5 d, P=0.002). ConclusionsFrom the analysis results of this cases data, patients with IVC filters don’t show obvious gender characteristics. The majority of them are young and middle-aged, and interventional method is mostly used for the removal of IVC filters. Patients who receive open surgery to remove the filter have a longer placement time in the IVC, suggesting the necessity of early removal of the IVC filter.
ObjectiveTo investigate therapeutic method, curative effect, and prognosis of inferior vena cava (IVC) blocking Budd-Chiari syndrome (BCS) with thrombosis. MethodsClinical data of 128 BCS patients with membranous or short-segment occlusion of IVC as well as IVC thrombosis, who accepted interventional treatment in The Affiliated Hospital of Zhengzhou University from Apr. 2004 to Jun. 2012, were retrospectively analyzed. Comparison of the difference on effect indicators between predilation group and stent filter group was performed. ResultsThereinto, 9 patients with fresh IVC thrombosis were treated with agitation thrombolysis (agitation thrombolysis group), 56 patients were predilated by small balloon (predilation group), for the rest 63 patients, a stent filter was deployed (stent filter group). Besides 1 stent filter fractured during the first removal attempt and had to be extracted surgically in the stent filter group (patients suffered with sent migration), in addition, the surgeries of other patients were technically successful without procedure-related complication. effect indicators were satisfactory in all patients, and there were no statistical differences between predilation group and stent filter group in dosage of urokinase, urokinase thrombolysis time, hospital stay, and incidence of complication (P > 0.05), but the cost of predilation group was lower than that of stent filter group (P < 0.01). All of the 128 patients were followed-up postoperation, and the duration range from 18 to 66 months with an average of 44.2 months. During the follow-up period, reobstruction of the IVC was observed in 13 patients without thrombosis, of which 1 patient in agitation thrombolysis group, 6 patients in predilation group, and 6 patients in stent filter group. There was no significant difference in recurrence rate between predilation group and stent filter group (P > 0.05). Patients with recurrence got re-expansion treatment, and no stenosis or thrombogenesis recurred. ConclusionsAgitation thrombolysis for fresh IVC trombosis in the patients with BCS is safe and effective. Predilation and stent filter techniques are all effective in the treatment of BCS with chronic IVC thrombosis, but the former technique seems to be more economic.
【Abstract】ObjectiveTo report the author’s experience with the first case of an adult-to-adult living donor liver transplantation (LDLT) for Budd-Chiari syndrome (BCS) using cryopreserved vena cava graft in postheptic vena cava reconstruction. MethodsA 35-year-old male patient with a diagnosis of BCS complicated with inferior vena cava (IVC) obstruction received medical treatment and radiologic intervention for nine months, no relief of the symptoms could be achieved. Finally, the patient underwent LDLT, which required posthepatic vena cava reconstructed using cryopreserved vena cava graft. ResultsThe patient has had an uneventful course since the LDLT. ConclusionWe believe that LDLT combined with posthepatic IVC reconstruction using cryopreserved vena cava graft is considered to be a sound modality for IVC obstructed BCS.
ObjectiveTo assess the therapeutic effect of catheter thrombolysis combined with inferior vena cava (IVC) filter placement in treatment of deep venous thrombosis (DVT) complicated with floating IVC thrombus. MethodsThe clinical data of 16 patients with DVT complicated with floating IVC thrombus from July 2013 to November 2014 in this hospital were collected. These patients were treated with the catheter thrombolysis combined with IVC filter placement, the IVC filter was placed via jugular vein, the catheter thrombolysis was performed by the side of the small saphenous vein, the amount of urokinase was (60-80) ×104 U/d. Results①The floating IVC thrombi of 13 patients were disappeared following catheter thrombolysis combined with IVC filter placement therapy, a small amount of visible thrombi were adhered on the recycled IVC filter, the lower limb swelling was relieved, the IVC could effectively open.②The IVC filters of 2 patients could not be recycled due to the adhesion of floating IVC thrombus and lumen of IVC resulting in luminal stenosis.③The floating IVC thrombus of 1 patient was disappeared, the IVC filter could not be recy-cled due to a large of thrombi adhered on the IVC filter. The lower limb swelling was slowly relieved. The complications such as severe pulmonary embolism didn't happen in all the patients during treatment and following-up. ConclusionThe limited data preliminarily shows that it is an effective and safe method by catheter thrombolysis combined with IVC filter placement in treatment of DVT complicated with floating IVC thrombus.

Methods Sixty-two patients treated with placement of inferior VCF from January 2008 to May 2010 were randomly divided into experimental group (n=32) and control group (n=30). Health education pathway and routine general way were adopted respectively to treat patients in the experimental group and the control group. Results Standard-achieving rate of the health education in the experimental group was significantly higher than that in the control group (Plt;0.05), and the incidence of anxiety was also lower in the experimental group. Conclusion Health education pathway for patients treated with placement of inferior VCF can increase the patients’ health care knowledge, lessen patients’ anxiety, and strengthen the nurse-patient communication and harmonious relations.
ObjectiveTo summarize short-term and long-term effects of ex vivo liver resection followed by autotransplantation (Abbreviation: autotransplantation) in treatment of advanced hepatic alveolar echinococcosis (HAE).MethodThe clinical data and follow-up data of 17 patients with advanced HAE who underwent autotransplantation from November 2016 to July 2019 in the Ganzi Tibetan Autonomous Prefecture People’s Hospital were retrospectively analyzed.ResultsThe autotransplantations were performed successfully in the 17 patients with advanced HAE. Ten patients underwent the inferior vena cava (IVC) reconstruction with autologous saphenous veins, 5 patients underwent the artificial revascularization, 1 patient underwent the direct anastomosis of the original IVC, and 1 patient didn’t reconstructed (the retroperitoneal collateral circulation was abundant). The mean liver graft mass was 681.3 g (365–1 350 g) and operation time was 11.5 h (9–16 h). The median anhepatic period was 312 min (175–450 min), blood loss was 2 000 mL(950–4 500 mL), red blood cell suspension transfusion was 6.4 U (1–20 U), and fresh frozen plasma was 1.1 L (0.8–2.0 L). The postoperative hospital stay was 5 to 45 d with an average of 25.6 d. There were 4 patients with the postoperative hepatic enveloping effusion, 1 patient with bile leakage, and 1 patient with bile duct stenosis. All of them were treated and cured, and no death occurred. The follow-up time of 17 patients was 3 to 35 months with an average of 9.5 months, no recurrence of HAE and distant metastasis were observed.ConclusionsIn highlands, autotransplantation in treatment of advanced HAE patients with different IVC reconstruction is satisfactory, but it has a higher risk and is difficult. Choice of intraoperative reconstruction materials, judgment of posterior peritoneal collateral circulation, presence or absence of tension in end-to-end anastomosis of the IVC require precise consideration. At the same time, anticoagulation therapy and complications management are difficult, and it is only suitable for plateau medical center with rich experience.
