Testes de Triagem Prevendo Metástase de Câncer na Etiologia do Derrame Pericárdico: HALP Score e PNI / Screening Tests Predicting Cancer Metastasis in the Etiology of Pericardial Effusion: HALP Score and PNI

Resumo Fundamento: A triagem do câncer é absolutamente necessária em pacientes com derrame pericárdico, pois o câncer é uma das doenças mais graves em sua etiologia. Estudos anteriores indicaram que o índice de inflamação imunológica sistêmica (IIS), o índice prognóstico nutricional (PNI) e o escore de hemoglobina, albumina, linfócitos e plaquetas (HALP) podem ser escores relacionados ao câncer. Objetivos: Este estudo foi iniciado considerando que esses sistemas de pontuação poderiam prever o câncer na etiologia de pacientes com derrame pericárdico. Métodos: Os pacientes submetidos à pericardiocentese entre 2006 e 2022 foram analisados retrospectivamente. A pericardiocentese foi realizada em um total de 283 pacientes com derrame pericárdico ou tamponamento cardíaco de moderado a grande no período especificado. Os índices de HALP, PNI e IIS foram calculados do sangue venoso periférico retirado antes do procedimento de pericardiocentese. O nível de significância estatística foi aceito em p<0,05. Resultados: O escore HALP foi de 0,173 (0,125-0,175) em pacientes com câncer. Detectou-se que em pacientes não oncológicos o escore foi de 0,32 (0,20-0,49; p<0,001). O escore de PNI foi de 33,1±5,6 em pacientes com câncer. Detectou-se que em pacientes não oncológicos o escore foi 39,8±4,8 (p<0,001). Conclusão: Os escores HALP e PNI são testes de triagem de câncer fáceis e rápidos que podem prever metástases de câncer na etiologia de pacientes com derrame pericárdico.

Abstract Background: Cancer screening is absolutely necessary in patients with pericardial effusion, given that cancer is one of the most serious diseases in the etiology of pericardial effusion. In previous studies, it was stated that the systemic immune-inflammation index (SII); the prognostic nutrition index (PNI); and the hemoglobin, albumin, lymphocyte, platelet (HALP) score can produce scores related to cancer. Objectives: This study began considering that these scoring systems could predict cancer in the etiology of patients with pericardial effusion. Methods: This study produced a retrospective analysis of patients who underwent pericardiocentesis between 2006 and 2022. Pericardiocentesis was performed in a total of 283 patients with moderate-to-large pericardial effusion or pericardial tamponade within the specified period. HALP, PNI, and SII scores were calculated according to the peripheral venous blood taken before the pericardiocentesis procedure. The statistical significance level was set at p<0.05. Results: The HALP score proved to be 0.173 (0.125-0.175) in cancer patients and 0.32 (0.20-0.49) in non-cancer patients (p<0.001). The PNI score proved to be 33.1±5.6 in cancer patients and 39.8±4.8 in non-cancer patients (p<0.001). Conclusion: The HALP score and PNI proved to be easy and fast cancer screening tests that can predict cancer metastasis in the etiology of patients with pericardial effusion.

Pharmaceutical care for rare ADR in a patient with ALK-positive non-small cell lung cancer induced by alectinib / 中国药房

OBJECTIVE To provide reference for safe drug use in patients with anaplastic lymphoma kinase （ALK）-positive non-small cell lung cancer （NSCLC）. METHODS Clinical pharmacists participated in the diagnosis and treatment of a patient with ALK-positive NSCLC who developed bilateral pleural effusion and hemolytic anemia after taking alectinib； regarding symptoms such as pleural effusion and hemolytic anemia in the patient， clinical pharmacists investigated the patient’s history of medication and disease， as well as potential drug interaction； to consider the correlation between the patient’s use of alectinib and the duration of pleural effusion and hemolytic anemia， clinical pharmacists suggested that clinical doctors discontinued alectinib and used reduced dose treatment after the pleural effusion improved， but the patient suffered from bilateral pleural effusion and hemolytic anemia again； after evaluating the correlation between alectinib and bilateral pleural effusion and hemolytic anemia using the Naranjo’s assessment scale， clinical pharmacists recommend permanent discontinuation of alectinib and jointly recommend replacement with ensartinib with clinical physicians. RESULTS Physicians adopted the suggestions of clinical pharmacists. The pleural effusion subsequently regressed and hemolytic anemia improved after replacing the drug. The correlation between alectinib and bilateral pleural effusion and hemolytic anemia was confirmed. CONCLUSIONS Clinical pharmacists participate in pharmaceutical monitoring of ALK-positive NSCLC patients， assist clinical doctors in developing personalized medication recommendations， and ensure the safety of patient medication.

Investigation and Ethical Consideration of Perioperative Complications in Patients with Liver Transplantation / 中国医学伦理学

To explore the prevention and treatment of perioperative complications of adult liver transplantation patients from the perspective of ethics, and carry out ethical thinking in order to provide theoretical support. Through a cross-sectional study, 189 patients selected by strict admission criteria who received liver transplantation in the department of hepatobiliary surgery of the First Affiliated Hospital of Xi’an Jiaotong University from January 2018 to May 2019, to explore the incidence and ethical problems of perioperative complications in adult liver transplantation. The results showed that 87 patients had complications among 189 patients, the incidence was 46.03%. Among them, 28 patients with pleural effusion, the incidence was 14.81%; 15 patients with biliary complications, the incidence was 7.94%; 14 patients with diabetes mellitus, the incidence was 7.41%. The incidence of complications after liver transplantation is high, mainly including pleural effusion, biliary complications and diabetes mellitus. Thus, the prevention and intervention from the perspective of nursing ethics is worth exploring.

A bleeding heart: case report and review of pericardial angiosarcoma

Abstract Primary cardiac tumors are rare. The cardiac sarcomas are the most common malignant cardiac tumors. These tumors have a dismal prognosis with an overall median survival of 25 months. Clinical features include dyspnea, arrhythmias, pericardial effusions, heart failure, and sudden cardiac death. The diagnosis is often challenging. Therefore, the cardiac imaging workup plays a central role in addition to a high clinical suspicion in the setting of atypical presentations that do not respond to standard therapies. The echocardiography, computed tomography, and cardiac MRI are crucial in clinching the diagnosis. Multimodal treatment with surgery, chemotherapy, and radiotherapy has been shown to improve outcomes, as opposed to using either of these modalities alone. We describe the case of a 30-year-old gentleman with COVID-19 infection who developed recurrent hemorrhagic pericardial effusions refractory to standard treatment and was eventually diagnosed as a case of pericardial angiosarcoma after his biopsy revealed the diagnosis and staging was performed using PET-CT-FDG scan. Our case re-emphasizes the importance of considering a malignant etiology early in the course of the disease presentation, especially in recurrent hemorrhagic effusions despite an inflammatory cytologic diagnosis of fluid. It also highlights the place for cardiac CT and MRI to ascertain the location and spread and to plan the further course of treatment. If diagnosed early, the estimated survival time can be prolonged by instituting a multimodal approach.

Evaluation of the RAPID score as a predictor of postoperative morbidity and mortality in patients undergoing pulmonary decortication for stage III pleural empyema

Abstract Objective: This study aims to correlate the RAPID score with the 3-month survival and surgical results of patients undergoing lung decortication with stage III pleural empyema. Methods: This was a retrospective study with the population of patients with pleural empyema who underwent pulmonary decortication between January 2019 and June 2022. Data were collected from the institution's database, and patients were classified as low, medium, and high risk according to the RAPID score. The primary outcome was 3-month mortality. Secondary outcomes were the length of hospital stay, readmission rate, and the need for pleural re-intervention. Results: Of the 34 patients with pleural empyema, according to the RAPID score, patients were stratified into low risk (23.5 %), medium risk (47.1 %), and high risk (29.4 %). The high-risk group had a 3-month mortality of 40 %, while the moderate-risk group hada 6.25 % and the low-risk group had no deaths within 90days, confirmingagood correlation with the RAPID score (p < 0.05). Sensitivity and specificity for the primary outcome in the high-risk score were 80.0 % and 79.3%, respectively. The secondary outcomes did not reach statistical significance. Conclusions: In this retrospective series, the RAPID score had a good correlation with 3-month mortality in patients undergoing lung decortication. The morbidity indicators did not reach statistical significance. The present data justifies further studies to explore the capacity of the RAPID score to be used as a selection tool for treatment modality in patients with stage III pleural empyema.

Comparison between use of a pleural drainage system with flutter valve and a conventional water-seal drainage system after lung resection: a randomized prospective study

ABSTRACT BACKGROUND: There is still a debate regarding the most appropriate pleural collector model to ensure a short hospital stay and minimum complications. OBJECTIVES: To study aimed to compare the time of air leak, time to drain removal, and length of hospital stay between a standard water-seal drainage system and a pleural collector system with a unidirectional flutter valve and rigid chamber. DESIGN AND SETTING: A randomized prospective clinical trial was conducted at a high-complexity hospital in São Paulo, Brazil. METHODS: Sixty-three patients who underwent open or video-assisted thoracoscopic lung wedge resection or lobectomy were randomized into two groups, according to the drainage system used: the control group (WS), which used a conventional water-seal pleural collector, and the study group (V), which used a flutter valve device (Sinapi® Model XL1000®). Variables related to the drainage system, time of air leak, time to drain removal, and time spent in hospital were compared between the groups. RESULTS: Most patients (63%) had lung cancer. No differences were observed between the groups in the time of air leak or time spent hospitalized. The time to drain removal was slightly shorter in the V group; however, the difference was not statistically significant. Seven patients presented with surgery-related complications: five and two in the WS and V groups, respectively. CONCLUSIONS: Air leak, time to drain removal, and time spent in the hospital were similar between the groups. The system used in the V group resulted in no adverse events and was safe.

Características clínicas, diagnóstico e tratamento de mulher com síndrome de Meigs: relato de caso e revisão narrativa / Clinical characteristics, diagnosis and treatment of a woman with Meigs syndrome: case report and narrative review

O objetivo deste estudo é descrever o caso de mulher com síndrome de Meigs e apresentar a revisão narrativa sobre o tema. Paciente do sexo feminino, 30 anos, nulípara, encaminhada ao hospital por massa anexial e história prévia de drenagem de derrame pleural. Evoluiu com instabilidade hemodinâmica por derrame pleural hipertensivo à direita, sendo submetida a drenagem torácica, com citologia do líquido negativa. Após, foi submetida a laparotomia: realizada salpingo-ooforectomia esquerda. A congelação e a análise histopatológica diagnosticaram fibroma ovariano. A citologia ascítica foi negativa. CA-125 elevado, presença de derrames cavitários e exame de imagem suspeito podem mimetizar um cenário de neoplasia maligna de ovário em estágio avançado. Entretanto, na síndrome de Meigs clássica, o tratamento é cirúrgico, sendo o diagnóstico obtido por meio da análise histopatológica do tumor ovariano. O manejo da síndrome de Meigs clássica é cirúrgico e, após a remoção do tumor, o derrame pleural e a ascite desaparecem.

To describe a case of Meigs syndrome and present a narrative review of the condition. Female patient, 30 years old, nulliparous, referred to the hospital due to an adnexal mass and a previous drainage of pleural effusion. She developed hemodynamic instability due to a hypertensive right pleural effusion being submitted to chest drainage, with negative cytology of the fluid. She underwent laparotomy: Left salpingo-oophorectomy was performed and frozen section and histopathological analysis diagnosed an ovarian fibroma. Ascites cytology was negative. Elevated CA-125, presence of cavitary effusions, suspicious imaging exam can mimic a scenario of ovarian cancer at an advanced stage. However, in classical Meigs syndrome, treatment is surgical, and the diagnosis is obtained through histopathological analysis of the ovarian tumor. Classical Meigs syndrome' management is surgical. After tumor removal, pleural effusion and ascites resolve.

Pleural empyema after COVID-19: A delayed presentation

Globally, the number of coronavirus disease-2019 (COVID-19) cases and deaths shows a declining trend since a peak in January 2022. For now, the pandemic phase looks to be ended, until a severe new variant may trigger another wave. At present, in India, small pockets of COVID-19 cases and post-COVID complications are still being reported. Therefore, physicians should remain vigilant about the atypical presentations and potential delayed or long-term complications of SARS-CoV-2 infection, even in individuals who had a mild COVID-19 infection. Here, we present the case of a 52-year-old male patient with a history of hypertension, who is a non-smoker and developed culture-negative pleural empyema 7 months after a mild COVID-19 infection. The patient was successfully treated with antibiotics and early video-assisted thoracoscopic surgery

A comparative study of conventional cytology and cell block in the diagnosis of pleural effusion with special reference to immunohistochemistry

Background: Body cavity fluids are evaluated by cell block (CB) technique. In conventional cytological smears (CS), appropriate identification of the cells as either reactive mesothelial cells or malignant cells is a diagnostic problem. In CB method, there is increase in cellularity, so it gives more morphological details of cells and improving the sensitivity of diagnosis. Sections obtained by CB method are also can be stored for future study like immunohistochemistry (IHC). Aims and Objectives: The aim of the study was to determine the diagnostic efficacy of CB technique over conventional CS and to study of IHC in CB of malignant pleural effusion. Materials and Methods: This will be institution-based, cross-sectional, and observational study. The pleural fluid (except blood and pus) obtained by thoracocentesis from both male and female patient (>18 years of age) 100 cases was included in the study. Pleural fluid mixed with blood/pus, fluid from cystic lesion, and inadequate sample (<15 ml vol.) were excluded in the study. Results: Association between architectural pattern in CB versus architectural pattern in cytology smear showed statistically significant value Chi-square: 201.7417, P < 0.0001. Conclusion: We may conclude that CB technique is better than conventional cytology smear technique especially in case of malignant pleural effusion. It increases true positive cases and decreases false negative cases. It also increases cellularity, maintain architectural pattern, and cellular morphology.

Surgery for Otitis Media with Effusion: A Survey of Otolaryngologists Who Treat Children in Brazil

Abstract Introduction Myringotomy and ear tube placement (MTP) is the surgical treatment for otitis media with effusion (OME), and it is the most common surgery performed in children. Several guidelines have been developed to assist in the care of patients who become candidates for MTP. Objectives To evaluate the practice of Brazilian otorhinolarynogologists when performing MTP according to the years of clinical experience. Secondarily, we also want to assess if their practice regarding MTP varied according to the percentage of children treated and the location of their practice. Methods A 30-question survey was sent to otolaryngologists affiliated with the Brazilian Academy of Pediatric Otorhinolaryngology (Academia Brasileira de Otorrinolaringologia Pediátrica, ABOPe, in Portuguese) and/or the Scientific Department of Otorhinolaryngology of the Brazilian Society of Pediatrics (Sociedade Brasileira de Pediatria, SBP, in Portuguese). The questions included were carefully chosen to provide a profile about the practices adopted in the pre-, peri- and postoperative periods of MTP. Results The questionnaire was sent to 208 otolaryngologists, and there were 124 (59.6%) respondents. Of those, 59.7% use antiseptics before surgery. Only 54 otolaryngologists, less than half of the subjects in this study (43.5%), always place a tube during the procedure. More physicians who practice in small cities recommend water precautions after MTP when compared to other physicians (p < 0.001). Conclusions The present study reveals that many respondents do not follow some of the recommendations of the current guidelines of the American Academy of

Profile of Cardiac Involvement in Children After Exposure to COVID-19

Objective: To evaluate the incidence and pattern of cardiac involvement in children postCOVID (coronavirus disease) infection in a tertiary care referral hospital in India. Methods: A prospective observational study was conducted including all consecutive children with suspected MIS-C referred to the cardiology services. Results: Of the 111 children with mean (SD) age 3.5 (3.6) years, 95.4% had cardiac involvement. Abnormalities detected were coronary vasculopathy, pericardial effusion, valvular regurgitation, ventricular dysfunction, diastolic flow reversal in aorta, pulmonary hypertension, bradycardia and intracardiac thrombus. The survival rate post treatment was 99%. Early and short-term follow-up data was available in 95% and 70%, respectively. Cardiac parameters improved in the majority. Conclusion: Cardiac involvement post COVID-19 is often a silent entity and may be missed unless specifically evaluated for. Early echocardiography aids in prompt diagnosis, triaging, and treatment, and may help in favorable outcomes.

Giant Left Atrial Appendage Aneurysm or Pericardial Effusion: A Misleading Appearance on Echocardiography and a High Risk of Rupture

Left atrial appendage (LAA) aneurysm or giant LAA is an uncommon condition. It could be discovered incidentally during echocardiography examination or in symptomatic patients presenting with tachycardia or embolic events. The giant LAA is a serious condition with a high embolic risk that can cause respiratory distress and even cardiac arrest in children. A conservative surgical approach based on resection of the LAA is recommended and is mostly safe. We report the case of a four-year-old girl presenting with a symptomatic giant LAA removed successfully. The echo-cardiographer must be aware of its appearance mimicking a pericardial effusion and focus on its possible association with other congenital lesions. There are several therapeutic strategies, all with proven efficacy and safety.

A rare case of tuberculous polyserositis � A case report

Polyserositis is defined as chronic inflammation of several serous membranes with effusions in serous cavities like Pericardial, Pleural and Peritoneal membranes, resulting in fibrous thickening of the serous membranes and sometimes constrictive pericarditis. There are various causes of polyserositis which include autoimmune diseases, neoplasia, endocrine diseases, drug � related causes and infectious diseases such as tuberculosis. Polyserositis in disseminated TB is a very rare presentation. Diagnosis is often delayed due to the non-specific presentation like polyserositis and its unusual nature. We herewith report a rare case of TB polyserositis, involving pleura, pericardium and peritoneum.

Thymoma: A rare presentation as recurrent pericardial effusion

Recurrent pericardial effusion is always complicated for the primary care physician to diagnose, and it often goes undiagnosed. Thymoma is rare cancer, but it is the most common tumor in the anterior mediastinum. It can present in a variety of ways; it can be asymptomatic for an extended period of time and only rarely as pericardial effusion. A 68‑year‑old male presented to us with two episodes of pericardial effusion in the previous 2 years and was later diagnosed with thymoma.

Prevalence of middle ear effusion among children with adenoid hypertrophy at a national referral hospital in Tanzania

Introduction: Middle ear effusion (MEE) is a common childhood disorder that causes hearing impairment due to the presence of fluid in the middle ear which reduces the middle ear's ability to conduct sound. Temporary or persistent hearing loss as a result of MEE causes speech, language and learning delays in children. There are few studies on MEE in Tanzania despite the huge burden of hearing loss among children with adenoid hypertrophy which is a known risk factor for MEE. Method: A cross-sectional study was conducted among 420 children aged nine years and below having adenoid hypertrophy with or without MEE. The diagnosis of adenoid hypertrophy was confirmed with a lateral view x-ray of the nasopharynx and tympanometry for cases with MEE. The primary objective of the study was to assess the prevalence of MEE among children with adenoid hypertrophy. Results: The prevalence of MEE among children with adenoid hypertrophy was 61.7%, with 218 (51.9%) males and 202 (48.1%) females. The most affected age group was 2-4 years with an incidence 193 (46%) and in this age group, males (53.9%) were more affected than females (46.1%). Generally, males, 134 (51.7%) were more affected by MEE than females, 125 (48.3%) of all 259 children with MEE. In terms of age group predominance by MEE, children aged 3-4 years, 107(41.3%) were more affected than all other age groups. Additionally, 4 (1.5%) children with MEE presented with hearing loss. Conclusion: There is a high prevalence of MEE among children with adenoid hypertrophy but no significant association with hearing loss.

Pericardial-Peritoneal Window with a Subxiphoid Approach under Local Anesthesia for Refractory Pericardial Effusion / 日本心臓血管外科学会雑誌

Background: Pericardial effusion is a common finding with a wide spectrum of etiologies. Surgical management is recommended for a patient with intractable pericardial effusion which is resistant to medical treatment and causes cardiac tamponade. Various surgical approaches for pericardial effusion have been reported, for example thoracotomy, open abdominal surgery, video-assisted thoracic surgery, laparoscopic surgery, and subxiphoid approach. Objectives: We report the results of pericardial-peritoneal window using a subxiphoid approach under local anesthesia for refractory pericardial effusions. Methods: Five patients who underwent pericardial-peritoneal window surgery for refractory pericardial effusion between April 2011 to June 2022 were included in this study. The age of the patients was 61±14 years, and one (20%) was male. The comorbidities were four cases of autoimmune disease (two cases of scleroderma, one case of systemic lupus erythematosus, and one case of IgG4-related disease) (80%) and two cases of follicular lymphoma (40%). For comorbidities, steroids were administered in 2 patients (40%) and immunosuppressive drugs in 4 patients (80%). Colchicine was administered in 3 patients (60%) to treat pericardial effusions. Pericardiocentesis had been performed in 4 patients (80%) prior to surgery. Under local anesthesia in the supine position, a small incision was made at lower end of the sternum and the xiphoid process was resected. A pericardial-peritoneal window of more than 40 mm in diameter was created. In the past, only the diaphragmatic window was opened, but recently the diaphragmatic window and the anterior aspect of the pericardial sac membrane have been resected continuously to open the pericardial sac widely. Results: The operative time was 36±15 min. One complication was postoperative hemorrhage. There were no operative deaths or hospital deaths. Preoperative colchicine was discontinued in all patients after surgery. The mean postoperative follow-up was 2.7 years (0.5-5.9）, and no reaccumulation of pericardial effusion was observed in any of the patients. Conclusions: The pericardial-peritoneal window with a subxiphoid approach can be safely performed under local anesthesia, and if the window is created large enough, it could be a minimally invasive and effective treatment for refractory pericardial effusions.

Imbalance between myopic shift and the minimum amplitude of accommodation: a hypothesis for the pathogenesis of ocular hypertension secondary to drug-induced bilateral acute ciliochoroidal effusion / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To report 5 cases with drug-induced bilateral acute ciliochoroidal effusion(DBACE)and myopic shift, with or without ocular hypertension(OHT), summarize patients' clinical characteristics and recovery process of DBACE, and investigate the possible pathophysiological mechanism.METHODS:A retrospective observational case study conducted from June 2017 to February 2021. The included patients were subjected to a series of ocular examinations listed as follows: 1)best corrected visual acuity; 2)intraocular pressure(IOP); 3)slit-lamp microscopy; 4)fundus photography; 5)ultrasound biomicroscopy(UBM); 6)subjective optometry; 7)axial length and anterior chamber depth. All patients were followed up every 2d until the diopters were completely restored to the state before the disease onset.RESULTS:In total, 5 patients aged 10-45 years old, including 3 female and 2 male patients, were enrolled in this study. All patients were bilaterally involved(5/5), and had myopic shift(5/5), of whom 3 patients had OHT(3/5). With the increase of age, myopic shift decreased, while OHT increased. Based on OHT, the dynamic aggravation process of DBACE was subdivided into 2 stages, stage 1(myopic shift without OHT)and stage 2(myopic shift with OHT). With the deterioration of DBACE, when myopic shift approached or exceeded the minimum amplitude of accommodation(MAA), IOP gradually rose, and DBACE progressed from stage 1 to stage 2. With the recovery of DBACE after discontinuing the suspicious drugs, DBACE in stage 2 first returned to stage 1, and then returned to normal.CONCLUSION:Pathophysiological mechanism of DBACE was subdivided into 2 stages, including stage 1(myopic shift without OHT)and stage 2(myopic shift with OHT). The transition between the two stages depends on the imbalance between myopic shift and MAA.

Analysis of risk factors associated with acute Stanford type B aortic dissection complicated with pleural effusion and observation of the curative effect after intracavitary repair / 中华内科杂志

Objective:To investigate the risk factors of acute Stanford type B aortic dissection (TBAD) complicated with pleural effusion (PE) and the short-term and long-term outcomes of thoracic endovascular aortic repair (TEVAR).Methods:A case-control study. The clinical and imaging data of 1 083 patients with acute TBAD admitted to the General Hospital of Northern Theater Command from April 2002 to December 2020 were retrospectively analyzed, including 211 cases with pleural effusion and 872 cases without pleural effusion. The baseline analysis of the two groups of patients was performed. The risk factors associated with pleural effusion were analyzed by binary logistic regression, and the results were expressed as odds ratio ( OR) and 95% confidence interval ( CI). According to the quantity of pleural effusion, they were simultaneously divided into small pleural effusion group and medium large pleural effusion group, to compare the short-term and long-term effects of TEVAR patients with different amounts of pleural effusion. Results:The incidence of pericardial effusion (17.5% vs. 3.8%, P<0.001), anemia (21.3% vs. 12.5%, P=0.001), aortic spiral tear (49.8% vs. 37.8%, P=0.002), dissection tear over diaphragm (57.8% vs. 48.1%, P=0.011), serum creatinine [85 (69, 111) vs. 81 (67, 100) μmol/L, P=0.011] and white blood cell levels[(11.3±4.2)×10 9/L vs. (10.3±4.2)×10 9/L, P=0.002] in acute TBAD pleural effusion group were significantly higher than those in non-pleural effusion group, and the hemoglobin level was significantly lower than that in non-pleural effusion group [(128±20) vs. (133±17) g/L, P<0.05]. Logistic stepwise regression analysis showed that pericardial effusion ( OR=5.038,95% CI 2.962-8.568, P<0.001), anemia ( OR=2.047,95% CI 1.361-3.079, P=0.001), spiral tear ( OR=1.551,95% CI 1.030-2.336 , P=0.002) and elevated white blood cell ( OR=1.059,95% CI 1.011-1.102, P=0.005) were independent risk factors for TBAD complicated with pleural effusion. The incidences of all-cause death (4/19 vs. 1.5% vs. 0.9%, P<0.001), aortogenic death (4/19 vs. 0.7% vs. 0.7%, P<0.001) and aortic related adverse events (4/19 vs. 1.5% vs. 1.1%, P<0.001) in patients with large pleural effusion during TEVAR operation were significantly higher than those in patients with small pleural effusion and those without pleural effusion, and the differences were statistically significant. At 1 month follow-up after TEVAR, the incidence of all-cause death (4/16 vs. 3.3% vs. 1.6%, P<0.001), aortogenic death (4/16 vs. 0.8% vs.0.7%, P<0.001), aorta related adverse events (4/16 vs. 4.1% vs. 4.7%, P=0.013) and overall clinical adverse events (4/16 vs.9.8% vs. 6.7%, P=0.014) in the medium and large thoracic group were significantly higher than those in the small pleural effusion group and no pleural effusion group, and the differences were statistically significant. At 1 year follow-up after TEVAR, the incidence of all-cause death (4/15 vs. 4.9% vs. 3.9%, P=0.004), aortogenic death (4/15 vs.2.5% vs. 2.1%, P<0.001), aorta related adverse events (5/15 vs. 11.5% vs. 9.4%, P=0.012) and overall clinical adverse events (5/15 vs. 18.9% vs. 13.1%, P=0.029) in the medium and large thoracic group were significantly higher than those in the small pleural effusion group and no pleural effusion group, and the differences were statistically significant. Conclusions:Single center data showed that pericardial effusion, anemia, spiral tear and elevated white blood cell were independent risk factors for acute TBAD complicated with pleural effusion; the early (1 month) and long-term (1 year) rates of all-cause death, aortic mortality, aortic adverse events and overall clinical adverse events were significantly higher in TBAD patients with moderate pleural effusion after TEVAR, and moderate and large pleural effusion was an independent risk factor for near and long-term aortic related adverse events after TEVAR surgery.
