Gabapentinoids-Related Delirium Adverse Events: A Real-World Study from 2004 to 2022 Based on FAERS.

Purpose: This study comprehensively describes and evaluates the correlation between gabapentinoids and all types of delirium. Methods: We used AERSMine to select all adverse reaction data from 2004 Q1 to the 2022 Q4 in the FDA Adverse Event Reporting System (FAERS) database, and delirium events reported by gabapentinoids drugs were included in this study. Collected and analyzed the clinical details of these reports. We have developed four models. Among the four models, reporting odds ratio (ROR) and proportional reporting ratio (PRR) were used to evaluate the potential association between and delirium. We undertook a subgroup analysis for the age and sex cohorts. Results: A total of 2950 reports of gabapentinoids-related delirium was collected. Excluding cases with a history of delirium (Model 2), opioid drugs (Model 3), and other adverse events related to gabapentinoids drugs (Model 4), pain cases with gabapentin drugs as the main suspected drug were selected. In model 1, the reporting rates of delirium at the delirium and delirium tremens levels were higher in the gabapentinoids group than in the non-gabapentinoids group (ROR 1.09(1.05,1.13); ROR 1.54(1.16,2.04)). In model 2.3 the delira and the delirium level were higher in the gabapentinoids group (ROR 1.42(1.29,1.56), ROR 1.44(1.31,1.59); ROR 1.43(1.30,1.58), ROR 1.46(1.33,1.61)). There is no difference in delirium levels in Model 4. Delirium levels were higher in the gabapentinoids group than in the non-gabapentinoids group in ≥65 years old. The delirium and deliria levels were higher in the male group than in the female group. Conclusion: The delirium adverse reactions of the gabapentinoids group were significantly higher than those of non-gabapentinoids group in the first three models. However, with the removal of confounding factors, there was no significant difference in this type of adverse reaction in Model 4. In elderly and male patients, the incidence of delirium with gabapentinoids was significantly increased.

Application of arterial infusion ports in hepatic arterial infusion chemotherapy and embolization for advanced hepatocellular carcinoma.

OBJECTIVES: To investigate the safety and feasibility of subcutaneous implantable infusion ports in repeated hepatic arterial infusion chemotherapy (HAIC) for advanced hepatocellular carcinoma (HCC) in China. METHODS: A total of 237 patients who were clinically diagnosed with advanced HCC (CNLC III a/III b) in our hospitals from December 2020 to October 2022 were retrospectively analyzed. The approaches of HAIC were divided into 2 groups: arterial infusion port implantation (group A) and one-time femoral artery catheterization (group B) based on the physicians' suggestion and the patients' intention. The comfort level (evaluated with the General Comfort Questionnaire), complications and average inpatient expenditure were compared between the 2 groups. RESULTS: 116 patients were finally enrolled in the study (group A: 69; group B: 47) and completed HAIC (FOLFOX-4 regimen) according to the dosing schedules (mean: 6±1 cycles). The comfort level of group A was greater than that of group B (p<0.05). The average inpatient expenditure of group A was lower than that of group B (5.4±2.4 vs 10.4±1.9 thousand yuan RMB/cycle, p<0.05). No patients developed port incision infection, hematoma or catheter-related thrombosis in group A, whereas four patients had groin hematomas, one had femoral artery dissection and four had deep vein thrombosis in group B. CONCLUSION: Hepatic arterial infusion chemotherapy via arterial infusion ports for advanced HCC decreased complications and medical expenditures and improved patient comfort levels compared with indwelling catheters.

Acute lower extremity arterial thrombosis associated with nephrotic syndrome in adults: case series and literature review.

BACKGROUND: Nephrotic syndrome (NS) is a condition associated with hypercoagulability. Thromboembolic events are a well-recognized complication of NS. Venous thrombosis is well known, while arterial thrombosis, which is more severe, occurs less frequently and is mainly reported in children in the literature. The aim of this study was to understand these rare adult cases of NS associated with acute lower extremity arterial thrombosis and draw attention to them to prevent misdiagnosis and delayed treatment. METHODS: From January 2011 and October 2022, we conducted a retrospective study of patients with NS and arterial thrombosis. Their clinical manifestations, imaging characteristics, treatments and outcomes were analyzed and compared, and a literature review was performed. RESULTS: Nine adults with NS and acute lower limb arterial thrombosis were described. In seven of these patients, six had fresh thrombi that preceded the NS diagnosis, while one had a history of NS for 14 years and previously underwent an emergency thrombectomy. Three of the seven patients eventually underwent above-knee amputations, and the other four underwent arterial revascularization with satisfactory recovery of lower-extremity perfusion. In addition to the seven patients mentioned above, the other two received successful anticoagulant treatment, as the thrombosis was present only in the popliteal artery. CONCLUSION: Acute lower extremity arterial thrombosis is a rare but serious and potentially lethal complication in patients with NS, and early recognition and appropriate management are crucial for good patient outcomes.

Preliminary application of three-dimensional venography and fusion navigation technique in May-Thurner syndrome.

OBJECTIVE: The purpose of this study was to report a technique for intraprocedural guidance of endovascular iliac vein stenting procedures using three-dimensional (3D) venography images as an overlay on live biplanar fluoroscopy. METHODS: Using 3D venography and a fusion navigation technique, percutaneous transluminal angioplasty and stent placement were performed to evaluate the feasibility of using 3D venography images and the fusion navigation technique to treat MTS compared with traditional digital subtraction angiography. The general epidemiologic data (ie, age, gender), clinical manifestations (ie, major symptoms, affected extremity, CEAP [clinical, etiology, anatomy, pathophysiology] classification, comorbidity, stenosis rate), intraoperative findings (ie, stent type, stent count, stent to inferior vena cava distance, procedure time, radiation dose, contrast agent dosage), and postoperative recovery were obtained and analyzed. RESULTS: A total of 30 consecutive patients with symptomatic MTS from our institution were enrolled in the present study. Of the 30 patients, 12 (group A) were treated using 3D venography images and fusion navigation and 18 (group B) were treated with two-dimensional venography images during endovascular management. Significant differences were observed between the two groups with respect to the procedure time (64.42 ± 4.35 minutes vs 76.61 ± 3.47 minutes; P = .04), radiation dose (2152 ± 124.7 mGy vs 2561 ± 105.6 mGy; P = .02), and contrast agent dosage (71.42 ± 4.87 mL vs 86.17 ± 4.14 mL; P = .03). CONCLUSIONS: 3D venography and its fusion navigation technique can improve prediction of the coverage area of the stent. Its use can also shorten the procedure time and reduce the contrast agent dose and radiation exposure, making it a valuable tool for both the diagnosis and the treatment of symptomatic MTS.

Exploration of risk factors for hemoglobinuria and acute kidney injury following iliofemoral venous mechanical thrombectomy.

Objective: To evaluate the risk factors for hemoglobinuria and acute kidney injury (AKI) after percutaneous mechanical thrombectomy (MT) with or without catheter-directed thrombolysis (CDT) for iliofemoral deep vein thrombosis (IFDVT). Methods: Patients with IFDVT who had MT with the AngioJet catheter (group A), MT plus CDT (group B), or CDT alone (group C) from January 2016 to March 2020 were retrospectively evaluated. Hemoglobinuria was monitored throughout the treatment course, and postoperative AKI was assessed by comparing the preoperative (baseline) and postoperative serum creatinine (sCr) levels from the electronic medical records of all patients. AKI was defined as an elevation in the sCr level exceeding 26.5 â€‹µmol/L within 72 â€‹h after the operation according to the Kidney Disease Improving Global Outcomes criteria. Results: A total of 493 consecutive patients with IFDVT were reviewed, of which 382 (mean age, 56 â€‹± â€‹11 years; 41% of them were females; 97 in group A, 128 in group B, and 157 in group C) were finally analyzed. Macroscopic hemoglobinuria was evident in 44.89% of the patients of the MT groups (101/225, 39 in group A, and 62 in group B), with no significant difference between the groups (P â€‹= â€‹0.219), but not in the patients in group C. None of the patients developed AKI (mean sCr difference -2.76 â€‹± â€‹13.80 â€‹µmol/L, range â€‹= â€‹-80.20 to 20.60 â€‹µmol/L) within 72 â€‹h after surgery. Conclusions: Rheolytic MT is an independent risk factor for hemoglobinuria. A proper aspiration strategy, hydration, and alkalization following thrombectomy are particularly favorable for preventing AKI.

Evaluation of 3-dimensional rotational venography for the diagnosis of non-thrombotic iliac venous lesion.

Background: The purpose of this study was to determine the technical feasibility and safety of 3D rotational venography (3D-RV) in the diagnosis of non-thrombotic iliac vein lesions compared with traditional 2D-digital subtraction angiography (2-DSA). Methods: The general epidemiological data (including age, gender), clinical manifestations (including major symptom, affected extremity, CEAP classification, comorbidity, stenosis rate), and intra-operative findings (iliac vein indentation position, collateral circulation, procedure time, X-rays dose, contrast agent dosage) of 61 NIVL patients who were assessed by 3D-RV and traditional 2-DSA between October 2018 to October 2022 were obtained and analyzed. Results: A total of 61 consecutive patients with symptomatic NIVL from our institution were enrolled in this study. With the aggravation of iliac vein stenosis, the proportion of indicators such as contralateral formation and iliac vein compression indentation reflecting the severity of compression under 3D-RV reconstruction increased significantly. Also, significant differences were observed between the 3D-RV and 2-DSA groups concerning procedure time (10.56 ± 0.09 s vs. 12.59 ± 0.37 s; p < 0.01), X-ray dose (41.25 ± 0.21 mGy vs. 81.59 ± 1.69 mGy; p < 0.01) and contrast agent dosage (21.48 ± 0.24 mL vs. 33.69 ± 0.72 mL; p < 0.01). Contralateral iliac vein imaging (p = 0.002), pelvic collateral vein imaging (p = 0.03), and external iliac vein indentation (p = 0.001) were found to influence the severity of iliac vein compression. Conclusion: 3D-RV can display dynamic stereo image information of NIVL, augmenting the information obtained from traditional 2-DSA. Contralateral iliac vein imaging, pelvic collateral vein imaging, and external iliac vein indentation can be used to evaluate the severity of iliac vein compression to some extent.

Current status of spontaneous isolated celiac artery dissection.

BACKGROUND: This study aimed to evaluate the current status of spontaneous isolated celiac artery dissection (SICAD). METHODS: The English-language literature published in various databases before December 2020 was reviewed. All case reports and series were included. If multiple reports came from the same hospital and covered the same period, only the most recent report was considered. The clinical characteristics, imaging features, and treatment outcome were analyzed. RESULTS: The study enrolled 88 English language publications between January 1959 and December 2020, including 70 case reports, two case series, and 16 clinical studies. Overall, 316 cases of SICAD were reported in the studies, including 268 men and 44 women (unavailable for 4, men: women ratio: 6:1, p < 0.05). The median age was 50.5 years (range: 6-72) in men and 53.9 years (range: 41-67) in women. Most patients (83.54%, 264/316) complained about stomach pain, primarily in the epigastric region (38.61%, 122/316). The misdiagnosis rate in this study was 3.16% (10/316). The most commonly used imaging modality was computed tomography angiography (CTA), with 97.47% (308/316) cases reporting its use in diagnosis and/or management. The rate of symptom improvement with Conservative Management, with or without antithrombotic agents, was 92.45% (98/106) and 96.58% (141/146), respectively. The rate of symptom improvement after surgical recanalization was 100% (13/13). Moreover, endovascular management resulted in a 100% (50/50) symptom improvement rate. CONCLUSION: Conservative management is the first-line treatment for SICAD. The surgical or endovascular intervention had a high technical success rate, suggesting that it should be reserved for patients who have failed conservative treatment.

Percutaneous Left Atrial Appendage Occlusion Therapy: Evolution and Growing Evidence.

Atrial fibrillation (AF) is the most common cardiac arrhythmia and if untreated, significantly increases both the risk of intracardiac thrombus formation and ischemic stroke. In patients with nonvalvular AF (NVAF), the left atrial appendage (LAA) has been estimated to be the source of thrombus development in 91% to 99% of cases. Consequently, oral anticoagulation (OAC) to provide stroke prevention has become the standard of care for most AF patients; however, OACs are associated with a risk of bleeding and their efficacy depends on optimal patient compliance. In terms of alternative approaches to preventing embolic events, surgical LAA excision was attempted as early as in the late 1940s in patients with valvular AF; LAA excision remains a recommendation in surgical guidelines for NVAF patients who need open-heart coronary bypass or valvular replacement/repair surgeries. However, due to its invasive nature surgical LAA intervention has limited clinical application in present cardiology practice. Percutaneous LAA occlusion (LAAO) is increasingly being performed as an alternative to OAC for stroke prevention; this is particularly the case in patients at increased bleeding risk. Substantial progress has been made in percutaneous LAAO therapy since its inception some twenty years ago. Herein we systematically review both the critical literature that led to the development of LAAO, and the increasing clinical evidence supporting the application of this treatment strategy in NVAF. To this end we focus on recently published critical evaluations of United States Food and Drug Administration (US FDA) and Conformité Européenne (Commercial Sale of Licensed Product in the EU) (CE-Mark) approved LAAO devices, summarize the current status of LAAO therapy, and discuss the future perspectives regarding the knowledge and technology gaps in this area by recognizing the potential contributions of many ongoing but likely transformative clinical trials.

Case report: Cement entrapped in the inferior vena cava filter after pedicle screw augmentation.

Background: Cement leakage into the inferior vena cava (IVC) is one of the most common complications associated with cement vertebroplasty, and can lead to potentially life-threatening complications such as pulmonary cement embolism (PCE). Implantation of an IVC filter is effective in the prevention of fatal pulmonary embolism. Here, we present an extremely rarely case of cement entrapped in an IVC filter after pedicle screw augmentation, and discuss all similar cases reported in the literature. Case presentation: A 70-year-old female presented with significant back and lower extremities pain and was unable to walk. MRI of the lumbar spine revealed an osteoporotic compression fracture of the L1-L3. She underwent cement-augmented pedicle screws implanted at the L1 and L3 vertebral bodies. A retrievable IVC filter was implanted due to the presence of calf vein thrombosis before cement vertebroplasty. Cement leaked into the IVC and was trapped by the filter, rendering the filter unretrievable using a conventional method. The asymptomatic patient received rivaroxaban 20 mg daily for anticoagulant postoperatively and lifelong anticoagulation was administered to prevent secondary IVC and cemented filter thrombosis. Methods: A literature search was conducted utilizing the PUBMED/MEDLINE using the following terms: "vertebroplasty," "complication," "bone cement," and "inferior vena cava (IVC)," or "inferior vena cava (IVC) filter." All relevant articles published in English or in other languages with English abstracts since 1962 were included. Results: A total of 36 articles were retrieved according to the search strategy. Only 6 out of these 36 studies contained information regarding the inferior vena cava filter and cement. Of the patients, 85.7% (36/42) reported in the literature whose gender was known were female and 14.3% were male. 28.5% (45/158) patients with pulmonary arterial and cardiovascular complications. Conclusion: Cement embolization occurring in the IVC filter is rare. Accurate knowledge about the lumbar vertebral venous anatomy and skillful operation during vertebral cementoplasty should be required in clinical practice.

The Influence of School Atmosphere on Chinese Teachers' Job Satisfaction: The Chain Mediating Effect of Psychological Capital and Professional Identity.

Until today, the impact of organizational atmosphere on job satisfaction has still attracted the attention of researchers in the field of education to help decision-makers and school leaders improve the teachers' commitment, professional identity, and job satisfaction through the construction of the school environment. This study explored the impact of school atmosphere on the teachers' job satisfaction and examined the chain mediating role of psychological capital and professional identity. The school atmosphere, psychological capital, professional identity, and job satisfaction scales were used to investigate 648 primary and secondary school teachers in China. The bootstrap method was used to test the mediating effect. The results showed that school atmosphere had a positive predictive effect on the teachers' job satisfaction; psychological capital does not play a mediating role between school atmosphere and job satisfaction; professional identity plays a mediating role between school atmosphere and job satisfaction; psychological capital and professional identity play a chain mediating role between school atmosphere and job satisfaction. Therefore, this study proposes that schools adopt more effective school management strategies to build a positive school atmosphere to improve the teachers' psychological capital and professional identity to solve the practical problem of low job satisfaction among primary and secondary school teachers.

Metformin protects against abdominal aortic aneurysm by Atg7-induced autophagy.

BACKGROUND: Abdominal aortic aneurysm (AAA) is a pathological dilation of the abdominal aorta. It is often asymptomatic, yet it has a high susceptibility to rupture. Our previous study showed that metformin protected against the pathophysiology of AAA by reducing the activation of the PI3K/AKT/mTOR pathway. OBJECTIVES: To investigate the potential involvement of the autophagy-related pathways in AAA and the ability of metformin to modulate these effects. MATERIAL AND METHODS: The expression of autophagy-related proteins was detected with western blot in patients with AAA. Angiotensin II (Ang-II) was also used to construct an AAA model in mice and in vascular smooth muscle cells (VSMCs). The expression of Atg7 and Atg4 was determined using western blot assay. The Atg7 expression was regulated by overexpressed plasmid, siRNA (small interfering RNA), or metformin, and cell proliferation, migration, apoptosis and autophagy caused by Ang-II were examined. RESULTS: Autophagy-related proteins were increased in patients with AAA. The Ang-II also induced the expression of Atg7, and metformin reversed this effect both in vivo and in vitro. The suppression of Atg7 inhibited cell proliferation and cell migration, and reduced cell apoptosis and autophagy, while the overexpression of Atg7 enhanced cell proliferation and migration, and induced cell apoptosis and autophagy. Furthermore, Atg7 regulated the expression of the autophagy-related protein in Ang-II treated VSMCs. The Atg7-mediated autophagy was also attenuated by metformin. CONCLUSIONS: Metformin reduced autophagy in AAA and this effect was mediated by Atg7, suggesting that Atg7 is a potential downstream effector of metformin in protecting against the pathophysiology of AAA.

Irradiation stent insertion for distal biliary obstruction secondary to primary common biliary cancer.

PURPOSE: To assess the effectiveness and safety of irradiation stent insertion for patients with distal biliary obstruction (DBO) secondary to primary common biliary cancer. MATERIAL AND METHODS: Eighty-two consecutive patients with DBO secondary to primary common biliary cancer were treated via either normal (n = 45) or irradiation stenting (n = 37) between January 2013 and December 2019. The instant and long-term outcomes were compared. RESULTS: Technical success rates of normal and irradiation stenting were both 100%. Clinical success rates of normal and irradiation stenting were 91.1 and 100%, respectively (p = .179). Stent reobstruction was observed in 13 and 7 patients in the normal and irradiation stenting groups, respectively (p = .295). The median stent patency was 162 and 225 days in the normal and irradiation stenting groups, respectively (p < .001). The median survival was 178 and 250 days in the normal and irradiation stenting groups, respectively (p < .001). Cholangitis was, respectively, observed in 8 and 12 patients in normal and irradiation stenting groups (p = .124). CONCLUSION: Irradiation stenting is effective and safe for patients with DBO secondary to primary common biliary cancer and can prolong stent patency and survival.

Comparison of different embolic particles for superior rectal arterial embolization of chronic hemorrhoidal bleeding: gelfoam versus microparticle.

BACKGROUND: Whether different embolic particles with comparable diameter lead to similar beneficial effects in endovascular embolization of hemorrhoidal disease remains to be established. We sought to evaluate the efficacy and safety of different types of agents for superior rectal arterial embolization (SRAE) in patients with bleeding hemorrhoids. METHODS: Patients with recurrent episodes of internal hemorrhoidal bleeding and chronic anemia treated by SRAE in three tertiary hospitals between March 2017 and June 2020 were retrospectively evaluated. The patients were divided into two study groups based on the embolic materials: embolization with coils (2-3 mm) + gelfoam particles at 350-560 µm (Group A, n = 23), embolization with coils (2-3 mm) + microparticles at 300-500 µm (Group B, n = 18). The technical success, preliminary clinical efficacy (percentage of patients without hematochezia), postoperative complications and short-term follow-up outcomes were analysed. RESULTS: A total of 41 patients (27 males) with symptomatic hemorrhoids were included in the study, mean age was 47 ± 12 years (range 25-72). 39% (16) patients with grade II hemorrhoids while 61% (25) patients with grade III. The technical success rate of the embolization procedure was 100%, and the preliminary clinical efficacy (87.0% vs 88.9%) showed no significant difference between the 2 groups (p = 0.098). No patients reported post-procedural and short-term serious complications, such as infection, intestinal ischemia or massive hemorrhage during the follow-up period (range 6-15 months). CONCLUSIONS: Both gelfoam particles and microparticles with comparable diameter in the endovascular treatment of hemorrhoidal bleeding demonstrated similarly good short-term efficacy and safety profile.

Endoscopic metal stenting for malignant hilar biliary obstruction: an update meta-analysis of unilateral versus bilateral stenting.

INTRODUCTION: Malignant hilar biliary obstruction (MHBO) can arise in patients with malignant hilar hepatobiliary tumors or lymph nodules. Most MHBO patients are not suitable for surgical resection due to the advanced tumor stage. The only palliative treatment available is provided by endoscopic or percutaneous stenting. AIM: To compare the efficacy of endoscopic unilateral versus bilateral metal stent insertion for treating MHBO. MATERIAL AND METHODS: A search of the PubMed, Embase, and Cochrane Library databases identified all relevant studies published until June 2020. The meta-analysis was undertaken using RevMan v5.3. RESULTS: We identified 154 studies initially, eight of which were used in our meta-analysis. The eight studies included 818 MHBO patients treated using either endoscopic unilateral (n = 396) or bilateral (n = 422) metal stenting. No significant differences were observed between the two groups in clinical success rate (OR = 2.64; p = 0.18), complication rate (OR = 0.63; p = 0.46), or OS (HR = 1.03; p = 0.53). The bilateral group had a lower stent dysfunction rate without significance (OR = 1.43; p = 0.09). Significantly longer stent patency was observed in the bilateral group (HR = 1.28; p = 0.01). Technical success rate was significantly higher in the unilateral group (OR = 0.26; p = 0.04). Funnel plot analysis indicated an absence of publication bias related to the selected study endpoints. CONCLUSIONS: Our meta-analysis indicated that endoscopic unilateral stenting had a greater technical success rate for MHBO patients than bilateral stenting. However, the bilateral stenting could achieve longer stent patency.

Five-Year Outcomes and Cardiac Remodeling Following Left Atrial Appendage Occlusion.

PURPOSE: LAAO has been an alternative therapy to oral anticoagulants (OACs) for stroke prophylaxis in patients with nonvalvular atrial fibrillation (NVAF) with elevated CHA2DS2-Vasc score, but the long-term outcomes of LAAO and its impacts on cardiac electrical and mechanical remodeling remain to be learned. We aimed to describe the impact of left atrial appendage occlusion (LAAO) on atrial remodeling and cardiovascular outcomes within 5-year follow-up. PATIENTS AND METHODS: A total of 107 patients with nonvalvular atrial fibrillation (NVAF) undergoing LAAO in the Shanghai Tenth People's Hospital between January 2014 and July 2017 were included. All participants were followed for ECG, transthoracic echocardiography (TTE), and clinical outcomes (including cardiovascular death, heart failure, ischemic stroke/systemic embolism, and pericardial effusion) at 6 and 12 months, and thereafter every 12 months after LAAO discharge until 5 years. RESULTS: After LAAO, the left atrial diameter significantly increased at 6 months (48.6 ± 6.7 vs 46.5 ± 7.0 mm); heart rate decreased immediately after the procedure (78.5 ± 14.7 vs 85.3 ± 21.7 bpm) when compared with the pre-procedure level. The QTc interval prolongated to the highest value of 460.7 ± 46.8 ms at 6 months (pre-procedure level of 433.7±49.0 ms). All these changes return to the pre-procedure level within the follow-up. For clinical outcomes, 51 patients suffered the composite of cardiovascular death (n=4, 3.7%), heart failure (n=25, 23.4%), ischemic stroke/systemic embolism (n=22, 20.6%), and pericardial effusion (n=26, 26.2%). CONCLUSION: LAAO did not change ECG or TTE characteristics and nonprocedure-related pericardial effusion is common during long-term follow-up. Further studies are warranted to investigate the optimal time frame of anticoagulation in patients undergoing LAAO.

Outcome of AngioJet mechanical thrombus aspiration in the treatment of acute lower extremities deep venous thrombosis.

OBJECTIVES: The objective of this study was to evaluate the efficacy and safety in patients with acute lower extremity deep venous thrombosis who underwent pharmacomechanical thrombectomy (PMT, AngioJet mechanical thrombus aspiration). METHODS: In this retrospective, 424 consecutive patients with acute lower extremity deep venous thrombosis from three institutions were enrolled in the study from January 2015 to December 2018. Of these, patients were divided into two groups, AngioJet group (n = 186) and catheter-directed thrombolysis (CDT) group (n = 238). Evaluation indexes including limb circumference difference, length of stay (LOS), urokinase dosage, periprocedural complications, follow-up imaging findings and villalta scores were analyzed from the medical records. RESULTS: A total of 424 patients diagnosed with acute lower extremity deep venous thrombosis were collected in this study. These patients were categorized into AngioJet group and CDT group. Significant differences were observed between the two groups with respect to the thigh circumference difference (5.32 ± 1.85 cm vs. 4.69 ± 2.15 cm; p = 0.04), calf circumference difference (2.79 ± 1.54 cm vs. 2.35 ± 1.25 cm; p = 0.01), thigh detumescence rate (72.19 ± 19.55% vs. 65.35 ± 17.26%; p = 0.00) and calf detumescence rate (62.79 ± 18.56% vs. 55.75 ± 17.27%; p = 0.00). The mean dose of urokinase in AngioJet group was 95.16 ± 45.89 million IU significantly less than that in the CDT group 293.76 ± 42.71 million IU (p = 0.00). The overall bleeding complication rate was 9.91% (19 patients in AngioJet group and 23 patients in CDT group), which included three major (0.71%, 3/424) and 39 minor (9.2%,39/424) events. In the AngioJet group, serum creatinine (sCr) concentration and urine erythrocyte from the hemolysis caused by the mechanical process were higher than baseline data at admission (p = 0.00, p = 0.00). The postoperative red blood cell and hemoglobin in two groups were lower than baseline data (p = 0.00, p = 0.00). Compared with CDT, AngioJet thrombectomy has significantly lower estimated incidence of PTS in the follow-up. CONCLUSION: AngioJet thrombectomy has stronger clearance ability for acute lower extremity deep venous thrombosis leading to significant reduction in the consumption of hospital resources, total dose of thrombolytic agents, and infusion time, thereby preventing adverse bleeding events, but patients with renal insufficiency should be careful. Ideal short-term and medium-term efficacy and safety are certain.
