Management of refractory hepatic hydrothorax: a report of two cases and review of the literature / Manejo de hidrotórax hepático refractario: reporte de dos casos y revisión de la literatura

ABSTRACT Hepatic hydrothorax is a transudative pleural effusion in patients with cirrhosis. A 56-yearold cirrhotic patient presented with dyspnea and desaturation; his chest images showed a right pleural effusion. Another 66-year-old woman with cirrhosis, developed during her hospitalization acute respiratory failure, and her chest X- ray showed left pleural effusion. Initially, both patients were prescribed a dietary sodium restriction and diuretics. Nevertheless, they didn't have a good response so a chest tube was placed, and an octreotide infusion partially reduced the volume of the pleural drainage allowing a pleurodesis. We report two cases of refractory hepatic hydrothorax with multiple treatments including octreotide and pleurodesis.

RESUMEN El hidrotórax hepático se define como una efusión pleural de tipo trasudado en pacientes con cirrosis hepática. Un paciente cirrótico de 56 años se presentó a nuestro servicio de emergencias con disnea y desaturación. La radiografía de tórax reveló una efusión pleural derecha. Otra paciente de 66 años, también diagnosticada con cirrosis, desarrolló insuficiencia respiratoria aguda durante su hospitalización, presentando una efusión pleural izquierda en la radiografía de tórax. Inicialmente, ambos pacientes fueron sometidos a una dieta hiposódica y se les administraron diuréticos. Sin embargo, debido a la falta de respuesta adecuada, se les colocó un tubo de drenaje torácico y se les administró una infusión de octreótide, lo cual redujo parcialmente el volumen pleural y permitió la realización posterior de una pleurodesis. Presentamos dos casos de hidrotórax hepático refractario tratados con múltiples intervenciones terapéuticas.

Transjugular intrahepatic portosystemic shunt in decompensated cirrhotic patients in a tertiary hospital in southern Brazil

SUMMARY OBJECTIVE: The aim of the present study was to evaluate the outcomes of cirrhotic patients undergoing transjugular intrahepatic portosystemic shunt. METHODS: A retrospective longitudinal observational study was carried out evaluating 38 cirrhotic patients undergoing transjugular intrahepatic portosystemic shunt. The outcomes were evaluated in an outpatient follow-up period of 3 months. The assumed significance level was 5%. RESULTS: The indications for transjugular intrahepatic portosystemic shunt were refractory ascites in 21 (55.3%), variceal hemorrhage in 13 (34.2%), and hydrothorax in 4 (10.5%) patients. There was development of hepatic encephalopathy in 10 (35.7%) patients after transjugular intrahepatic portosystemic shunt. From the 21 patients with refractory ascites, resolution was observed in 1 (3.1%) patient, and in 16 (50.0%) patients, there was ascites control. Regarding transjugular intrahepatic portosystemic shunt after variceal bleeding, 10 (76.9%) patients remained without new bleeding or hospitalizations in the follow-up period. The global survival in the follow-up period in patients with and without hepatic encephalopathy was 60 vs. 82%, respectively (p=0.032). CONCLUSION: Transjugular intrahepatic portosystemic shunt can be considered in decompensated cirrhotic patients; however, the development of hepatic encephalopathy which can shorten survival should be focused.

¿Cuál es el rol actual de la toracocentesis en el hidrotórax fetal severo? Presentación de caso

Se llama hidrotórax a una efusión pleural primaria que ocurre durante la vida prenatal (denominado 'quilotórax primario' después del nacimiento). En ciertos casos, esta efusión es severa y produce compresión pulmonar y cardiaca, por lo cual, la mortalidad perinatal sigue siendo alta. Los recién nacidos con hidrotórax requieren, muchas veces, de drenaje, nutrición parenteral total y medicación específica para su recuperación. Sin embargo, las intervenciones prenatales, principalmente con derivaciones toraco-amnióticas, pueden mejorar estos resultados. Reportamos el caso de un feto con hidrotórax severo a quien se le realizó una toracocentesis y revisamos la literatura acerca de su rol en el tratamiento prenatal actual.

Hydrothorax is a primary pleural effusion that occurs during prenatal life (called "primary chylothorax" after birth). In certain cases, this effusion is severe and produces pulmonary and cardiac compression, and perinatal mortality remains high. Newborns with hydrothorax often require drainage, total parenteral nutrition and specific medication for their recovery. However, prenatal interventions, mainly with thoraco-amniotic shunts, can improve these results. We report the case of a fetus with severe hydrothorax who underwent thoracentesis and review the literature on its role in current prenatal management.

One-year outcome of patients with cirrhosis who developed spontaneous bacterial empyema: A cohort study.

OBJECTIVE: This study aimed to evaluate outcomes in cirrhotic patients diagnosed with spontaneous bacterial empyema (SBE) compared with those without this complication. METHODS: We performed a retrospective cohort study of cirrhotic patients from a tertiary care center. The primary outcome was time to death or liver transplantation (LT) within one year after diagnosis of infection. We integrated three groups: patients with SBE (group A), patients with spontaneous bacterial peritonitis (SBP; group B), and cirrhotic patients without SBP or SBE (group C), matched by age, model for end-stage liver disease-sodium (MELD-Na) score and year of infection. Outcomes were analyzed using a Cox regression model adjusted for cardiovascular risk factors and MELD-Na score. RESULTS: Between January 1999 and February 2019, 4829 cirrhotic patients were identified. Among them, 73 (1.5%) had hepatic hydrotorax, of whom 22 (30.1%) were diagnosed with SBE. Median age in group A was 58 years, 50% were men, and median MELD-Na was 21.5. Compared with group C, the hazard ratio of death or LT during the first year after infection was 2.98 (95% confidence interval [CI] 1.43-6.22, P = 0.004) for group A and 1.23 (95% CI 0.65-2.32, P = 0.522) for group B. CONCLUSIONS: Our results suggest that patients with SBE have a worse outcome during the first year after infection is diagnosed. Patients who develop SBE should be promptly referred for transplant evaluation. SBE may emerge as new indication that could benefit from MELD exception points.

Pleural Effusions Identified by Point-of-Care Ultrasound Predict Poor Outcomes in Decompensated Cirrhosis.

Chronic liver disease (CLD) may be associated with pleural effusions (PEs). This article prospectively evaluates whether detection of PEs on thoracic ultrasound (TUS) at the bedside independently predicts mortality and length of stay (LOS) in hospitalized patients with a decompensated CLD. A total of 116 consecutive inpatients with decompensated cirrhosis underwent antero-posterior chest radiographs (CXR) and TUS to detect PEs. Their median age was 54 y (interquartile range, 47-62), 90 (70.6%) were male, and 61 (52.6%) fell into the Child-Pugh class C categorization. TUS identified PEs in 58 (50%) patients, half of which were small enough to preclude thoracentesis. CXR failed to recognize approximately 40% of PEs seen on TUS. The identification of PEs by TUS was associated with a longer LOS (10 vs. 5.5 d, p < 0.001) and double mortality (39.7% vs. 20.7%, p = 0.021). In multivariate analysis, PEs were independently related to poor survival (hazard ratio 2.08, 95% confidence interval [CI] 1.02-4.25; p = 0.044). Patients with both Child-Pugh C stage and PEs had the lowest survival rate (70 vs. 317 d, p = 0.001). In conclusion, PEs identified by TUS in hospitalized patients with decompensated CLD independently predict a poor outcome and portend a longer LOS.

Preoperative Cervical Length Predicts the Risk of Delivery within One Week after Pleuroamniotic Shunt in Fetuses with Severe Hydrothorax.

OBJECTIVE: The objective of this study was to assess the predictive performance of preoperative cervical length (CL) for delivery within 1 week after pleuroamniotic shunting (PAS) in fetuses with severe hydrothorax. METHODS: A prospective cohort of fetuses with severe hydrothorax referred to our fetal surgery center in Querétaro, Mexico from January 2012 to July 2020. Severe fetal hydrothorax was diagnosed as an accumulation of fluid within the fetal pleural space accompanied with severe bilateral lung compression, mediastinal shift, polyhydramnios, and/or hydrops. Transvaginal CL was measured immediately before PAS, and a short cervix was defined as that <25 mm. The interval from fetal intervention to delivery, prevalence of preterm prelabor rupture of membranes (PPROMs), and associations with delivery within the first week after PAS according to a short or a normal CL, were evaluated. RESULTS: Thirty-five pregnancies with severe fetal hydrothorax treated with PAS were evaluated. Median gestational age at PAS was (weeks + days) 31+2 (range, 26+0-36+1). Two (5.7%) and 7 (20.0%) cases delivered within the first 24 h and 1 week after PAS, respectively. Ten (28.6%) women had a short cervix before PAS, while 25 (71.4%) had normal preoperative CL. Women with a short cervix showed lower mean interval between fetal intervention and delivery (2.4 vs. 5.5 weeks, p = 0.01), and higher prevalence of PPROM (50 vs. 12%, p = 0.01), as compared to women with a nonshort cervix. Preoperative short cervix was associated with significantly higher risk of delivery within the first 24 h (20.0 vs. 0%, respectively, p < 0.05) and 1 week after PAS (50.0 vs. 8.0%, respectively, p < 0.01) compared with pregnancies with normal preoperative CL. CONCLUSION: In pregnancies with severe fetal hydrothorax candidates for pleuroamniotic shunt, identification of a short cervix before fetal intervention can predict delivery within 1 week after the surgical procedure.

Fetal anesthesia for twin-to-twin transfusion syndrome and fetal hydrothorax drainage: case report / Anestesia fetal para síndrome de transfusión gemelar y drenaje de hidrotórax fetal: reporte de caso

Abstract Fetal surgery in utero is an alternative for treatable congenital malformations. Prognosis will improve with early correction. Once the surgical technique is planned, the anesthetist's knowledge of maternal and fetal physiology is crucial for the selection of the ideal anesthetic technique for each individual case, considering the type of surgical procedure and the expected degree of fetal stimulation. In this way, the optimal surgical field with maternal and fetal safety will be ensured. This article describes 1 case of twin-to-twin transfusion syndrome under spinal anesthesia and sedation, and a second case of hydrothorax drainage under sedation.

Resumen La cirugía fetal in útero es una alternativa para las malformaciones congénitas tratables, su intervención temprana mejora el pronóstico del feto. Una vez planeada la técnica quirúrgica el conocimiento del anestesiólogo sobre la fisiología materna y fetal es fundamental, puesto que deberá determinar la técnica anestésica ideal acorde al contexto de cada caso considerando el tipo de procedimiento quirúrgico a realizarse y el grado de estimulación fetal esperado. De esta manera se asegura un campo quirúrgico óptimo ofreciendo seguridad materno fetal. En este artículo se describen dos casos: el primero síndrome de transfusión gemelar se realizó bajo anestesia raquídea y sedación, en el segundo caso de drenaje de hidrotórax bajo sedación.

Describimos su evolución, diagnóstico y resolución

A case of right acute hydrotorax is reported in a 13 years old boy with terminal chronic renal failure in CPD (chronic peritoneal diálysis); it is a rare complication and in our experience in the chronic peritoneal dialysis program in Hospital del niño Jesus, Tucuman, in 12 years of duration is the first case. We inform the evolution, diagnosis and resolution.

Hidrotórax hepático: presentación de 3 casos con diferentes enfoques terapéuticos / Hepatic hydrothorax: presentation of 3 cases with different therapeutic approaches

El hidrotórax hepático (HH) se define como un derrame pleural mayor de 500 ml en pacientes con cirrosis e hipertensión portal. Representa una complicación infrecuente por lo general asociada con ascitis y su origen se relaciona con el paso de líquido ascítico a través de pequeños defectos en el diafragma de predominio en el hemitórax derecho. Una vez establecido el diagnóstico por imágenes, la toracentesis diagnostica permite confirmar un trasudado. La terapia inicial está basada en la restricción de sodio y el uso combinado de diuréticos. El 20-25% de los pacientes desarrolla un HH refractario, el cual requiere intervenciones invasivas tales como la derivación percutánea portosistémica intrahepática (DPPI), la reparación de los defectos diafragmáticos por videotoracoscopia asistida asociada a pleurodésis química y el uso de un catéter pleural tunelizado. No se recomienda la inserción de un tubo de tórax por su elevada morbilidad y mortalidad. El tratamiento definitivo del HH es el trasplante hepático el cual alcanza una excelente sobrevida. Presentamos tres casos de hidrotórax hepático con diferentes enfoques terapéuticos que incluyeron el manejo conservador con dieta y diuréticos, la inserción fallida de un tubo de tórax con pleurodesis y una DPPI.

Hepatic hydrothorax is uncommon transudative pleural effusion greater than 500 ml in association with cirrhosis and portal hypertension. Ascites is also present in most of the patients and the pathophysiology include the passage of ascites fluid through small diaphragmatic defects. After diagnostic thoracentesis studies, the first line management is restricting sodium intake and diuretics combination including stepwise dose of spironolactone plus furosemide. Therapeutic thoracentesis is a simple and effective procedure to relief dyspnea. Hepatic hydrothorax is refractory in approximately 20-25% and treatments options include repeated thoracentesis, transjugular intrahepatic portosystemic shunts (TIPS) placement, chemical pleurodesis with repair diaphragmatic defects using video-assisted thoracoscopy surgery (VATS), and insertion of an indwelling pleural catheter. Chest tube insertion carries significant morbidity and mortality with questionable benefit. Hepatic transplantation remains the best treatment option with long term survival. We present three cases of hepatic hydrothorax with different therapeutic approach including first line management, failed chest tube insertion and TIPS placement.

Derivación toracoamniótica en hidrotórax fetal: reporte de un caso / Thoracoamniotic shunt for fetal hydrothorax: A case report

We report a case of massive unilateral hydrothorax diagnosed in an 18-weeks-old fetus with a normal karyotype. The fetus was severely affected by hydrops and bradycardia since week 24. Initially, we performed pleurodesis, but the hydrothorax worsened and evolved into hydrops, so we proceeded to insert a transplacental thoracoamniotic shunt. Improvement was evident one week after the procedure, and the hydrothorax resolved during the remainder of the pregnancy. Following cesarean delivery at 37 weeks, the neonate required prolonged NICU stay. He was discharged after two months and remains stable until the present time.

Presentamos un caso de hidrotórax masivo unilateral diagnosticado a las 18 semanas de gestación en un feto con cariotipo normal. El feto fue afectado severamente por hydrops y bradicardia desde las 24 semanas. Inicialmente realizamos una pleurodesis, pero debido al empeoramiento del hidrotórax que evolucionó a hidropesía, procedimos con la inserción de una derivación toracoamniótica transplacentaria. La mejoría fue evidente una semana después del procedimiento, seguido por la resolución del hidrotórax durante el resto del embarazo. Después de una cesárea a las 37 semanas, el neonato requirió una estancia prolongada en la UCIN. Fue dado de alta a los 2 meses de edad y se ha mantenido estable hasta el momento actual.

Hidrotórax hepático en paciente con cirrosis por colangitis esclerosante primaria / Hepatic hydrothorax in a patient with cirrhosis due to primary sclerosing cholangitis

Se presenta el caso de un paciente de sexo masculino de 39 años, portador de colangitis esclerosante primaria desde hace 9 años, complicado con síndrome de hipertensión portal más insuficiencia hepática, en plan de trasplante hepático, en seguimiento por el Servicio de Gastroenterología. Ingresa por dificultad respiratoria, constatándose derrame pleural izquierdo extenso con características de trasudado con ascitis moderada, por lo que se procede al drenaje del líquido pleural y ascítico con goteo concomitante de albúmina endovenosa. El paciente presenta buena tolerancia y disminución importante tanto del derrame pleural como del líquido ascítico. Es dado de alta en mejores condiciones y con aumento de dosis de fármacos para el tratamiento de la ascitis

We present the case of a male patient 39 years old, with a history of primary sclerosing cholangitis for 9 years, complicated with portal hypertension and liver failure, he is in liver transplant program, followed up by Gastroenterology Service. He was admitted for respiratory failure, and massive left pleural effusion, with of features transudate and moderate ascites was noted aswell, we performes pleural and ascitic fluid drainage with concomitant infusion of intravenous albumin. The patient shows good tolerance and significant decrease in both pleural effusion and ascitic fluid. He was discharged in better condition and with increased doses of drugs for the treatment of ascites

Hepatic Hydrothorax.

Hepatic hydrothorax (HH) is a pleural effusion that develops in a patient with cirrhosis and portal hypertension in the absence of cardiopulmonary disease. Although the development of HH remains incompletely understood, the most acceptable explanation is that the pleural effusion is a result of a direct passage of ascitic fluid into the pleural cavity through a defect in the diaphragm due to the raised abdominal pressure and the negative pressure within the pleural space. Patients with HH can be asymptomatic or present with pulmonary symptoms such as shortness of breath, cough, hypoxemia, or respiratory failure associated with large pleural effusions. The diagnosis is established clinically by finding a serous transudate after exclusion of cardiopulmonary disease and is confirmed by radionuclide imaging demonstrating communication between the peritoneal and pleural spaces when necessary. Spontaneous bacterial empyema is serious complication of HH, which manifest by increased pleural fluid neutrophils or a positive bacterial culture and will require antibiotic therapy. The mainstay of therapy of HH is sodium restriction and administration of diuretics. When medical therapy fails, the only definitive treatment is liver transplantation. Therapeutic thoracentesis, indwelling tunneled pleural catheters, transjugular intrahepatic portosystemic shunt and thoracoscopic repair of diaphragmatic defects with pleural sclerosis can provide symptomatic relief, but the morbidity and mortality is high in these extremely ill patients.

Compromiso pulmonar en la enfermedad hepática: una actualización / Pulmonary commitment in hepatic disease: uma atualização / Compromisso pulmonar na doença hepática

La enfermedad Hepática es una causa importante de morbilidad y Mortalidad en el mundo; asociada a compromiso orgánico múltiple. En el pulmón, tres condiciones clínicas han sido descritas; estos cuadros Incluyen, el Síndrome Hepatopulmonar (SHP), que obedece a un trastorno de la oxigenación por dilatación de la vasculatura pulmonar. La hipertensión portopulmonar (HPP), mediada por desequilibrio entre agentes vasodilatadores y vasoconstrictores que conducen a un aumento de la presión media de la arteria pulmonar y por último el Hidrotórax Hepático (HH), que es la condición menos prevalente, se fundamenta principalmente en anomalías anatómicas del diafragma, con o sin relación a la presencia de ascitis. La presencia SHP o HPP es predictor independiente de mortalidad, resaltando su importancia en la elegibilidad de pacientes para trasplante hepático ortotópico como medida curativa.

Liver disease is a major cause of morbidity and mortality in the world; it is associated with multiple organ involvement. In the lung, three clinical conditions are described; these conditions include, Hepatopulmonary Syndrome (HPS), which is due to a oxygenation defect by the development of pulmonary vascular dilatation. Portopulmonary (HPP) hypertension, it's mediated by an imbalance between vasodilator and vasoconstrictor agents leading to an increase in mean pulmonary artery pressure and finally the Hydrothorax Liver (HH), that is the least prevalent condition, it's based on anatomical diaphragm abnormalities, with or without ascites. The presence of SHP or HPP is an independent predictor of mortality, highlighting its importance in the eligibility of patients for orthotopic liver transplantation as a curative measure.

A doença hepatica é uma das principais causas de morbidade e mortalidade no mundo; está associado ao compromisso de vários órgãos. No pulmão, três condições clínicas são descritas; estas condições incluem, Síndrome Hepatopulmonar (HPS), que é devido a um defeito de oxigenação do dilatação vascular pulmonar. A hipertensão portopulmonar (HPP), é mediada por um desequilíbrio entre vasodilatadores e agentes vasoconstritores, levando a um aumento da pressão arterial média da artéria pulmonar e, finalmente, ao hidrotorax hepatico (HH), essa é a condição menos prevalente, é baseada em anormalidades anatômicas do diafragma, com ou sem ascite. A presença de SHP ou HPP é um preditor independente de mortalidade, destacando sua importância na elegibilidade de pacientes para transplante de hepatico como medida curativa.

[Massive hydrothorax in a ease of hemolytic uremic syndrome: conservative treatment without interruption of peritoneal dialysis]. / Hidrotórax masivo en un caso de síndrome urémico hemolítico: tratamiento conservador sin interrupción de la diálisis peritoneal.

The hydrothorax is a known but rare complication of acute and chronic peritoneal dialysis. Patients with hemolytic uremic syndrome seem to be more prone to this complication. Usually discontinuation of treatment is necessary due to the lack of resolution or recurrence of hydrothorax and transfer to hemodialysis, but some patients can continue dialysis with modification of technique and with resolution of hydrothorax. CASE REPORT: a child with hemolytic uremic syndrome presented a massive hydrothorax during acute peritoneal dialysis which resolved with dialysis schema modification without interruption of treatment.

El hidrotórax es una complicación conocida pero infrecuente de la diálisis peritoneal aguda y crónica. Los pacientes con síndrome urémico hemolítico parecieran estar más predispuestos a esta complicación. Habitualmente, es necesaria la interrupción del procedimiento debido a la falta de resolución o recurrencia del hidrotórax y la transferencia a hemodiálisis. Sin embargo, algunos pacientes pueden continuar dializándose sin dificultad con alguna modificación de la técnica y resolución del hidrotórax. Se describe una niña con síndrome urémico hemolítico, que presentó un hidrotórax masivo durante la diálisis peritoneal aguda, que se resolvió con la modificación del esquema de diálisis sin interrupción del procedimiento.

Carcinoma de glandula mamaria en una yegua criolla colombiana. reporte de caso / Mammary gland carcinoma in a colombian criollo mare. case report

Los tumores mamarios son poco frecuente en equinos; Se han reportado prevalencias entre 0,11% y 2%, en plantas de beneficio; en Colombia no hay estudios que determinen la prevalencia de este tipo de enfermedad. Se presenta un caso clínico de una yegua de raza criollo colombiano con signos de depresión, tos, dificultad respiratoria y aumento de tamaño de la glándula mamaria con dolor. Debido a la severidad de los signos respiratorios se tomó la decisión de aplicar la eutanasia. En la necropsia se encontraron múltiples masas irregulares dentro de la cavidad torácica, nódulos firmes en los pulmones y la glándula mamaria de consistencia dura al corte. Según los hallazgos histopatológicos, el diagnóstico definitivo determinó un carcinoma de glándula mamaria tipo simple, papilar, grado III con metástasis pulmonar extensa. Este artículo es el primer reporte de una yegua criolla colombiana con diagnóstico de carcinoma mamario, metástasis pulmonar, la descripción de su presentación clínica y el respectivo diagnóstico histopatológico.

Breast cancer rarely occurs in horses. A prevalence that fluctuates from 0.11% to about 0.2% have been found in slaughter houses. Nevertheless, in Colombia there are not studies that have determined this disease prevalence yet. This article describes clinical sings and progress of a Colombian Criollo mare which was depressed with cough, respiratory distress, swollen and painful udder. Due to the unfavorable clinical progress the owner decides to euthanize the mare, on postmortem examination was found several irregular masses in thoracic cavity, multiple firm nodes disseminated in the lungs, and a mammary gland swollen and hard to cut. Microscopic examination reveal a mammary gland simple papillary carcinoma grade III with extensive lung metastasis. To the authors knowledge this is the first report on a breast carcinoma with pulmonary metastasis diagnosis made on this breed, its clinical presentation and histopathological diagnosis.

When one port does not return blood: two case reports of rare causes for misplaced central venous catheters / Quando uma porta não apresenta retorno sanguíneo: relato de dois casos de causas raras de mau posicionamento de cateter venoso central

We present two cases of misplaced central venous catheters having in common theabsence of free blood return from one lumen immediately after placement. The former is acase of right hydrothorax associated with central venous catheterization with the catheter tipin intra-pleural location. In this case the distal port was never patent. In the latter case therewas an increased aspiration pressure through the middle port due to a catheter looping.The absence of free flow on aspiration from one lumen of a central catheter should not beundervalued. In these circumstances the catheter should not be used and needs to be removed.

Apresentamos dois casos de mau posicionamento de cateter venoso central. Têmem comum a ausência do retorno sanguíneo livre em um dos lúmens imediatamente após acolocac¸ão. O primeiro é um caso de hidrotórax direito associado ao cateterismo venoso central,com a ponta do cateter em localizac¸ão intrapleural. Nesse caso, a porta distal nunca estevepatente. No segundo caso houve um aumento da pressão de aspirac¸ão através da porta medialpor causa da formac¸ão de alc¸a no cateter.A ausência de fluxo livre na aspirac¸ão de um lúmen do cateter central não deve ser subesti-mada. Nessas circunstâncias, o cateter não deve ser usado e deve ser removido.

When one port does not return blood: two case reports of rare causes for misplaced central venous catheters.

We present two cases of misplaced central venous catheters having in common the absence of free blood return from one lumen immediately after placement. The former is a case of right hydrothorax associated with central venous catheterization with the catheter tip in intra-pleural location. In this case the distal port was never patent. In the latter case there was an increased aspiration pressure through the middle port due to a catheter looping. The absence of free flow on aspiration from one lumen of a central catheter should not be undervalued. In these circumstances the catheter should not be used and needs to be removed.

Hemoneumotórax espontáneo: presentación de caso / Spontaneous Hemopneumothorax: A Case Report

El hemoneumotórax espontáneo es una condición inusual, caracterizada por la acumulación de aire y sangre en la cavidad pleural, no precedida por trauma. La radiografía de tórax es la herramienta principal en el diagnóstico de esta entidad. Se presenta el caso de un hombre de 22 años con hemoneumotórax espontáneo. El paciente se recuperó sin complicaciones luego de la cirugía.

Spontaneous hemopneumothorax is an unusual condition, characterized by the accumulation of air and blood in the pleural cavity, not preceded by trauma. Chest radiography is the main tool in the diagnosis of this entity. We present, a case of a 22-year-old male with spontaneous hemopneumothorax. The patient recovered after surgery with no complications.

Hidrotórax hepático: reporte de caso y revisión de la literatura / Hepatic hydrothorax: case report and literature review

El hidrotórax hepático es una complicación poco común que se da en pacientes con cirrosis hepática. Sepresenta el caso de una paciente con cirrosis por esteatohepatitis no alcohólica y evidencia de hipertensiónportal, y quien se presenta al servicio de urgencias con tos y dolor torácico; se le encuentra un derramepleural tipo trasudado por criterios de Light, asociado a ascitis, sin hallarse una causa cardíaca, pleural opulmonar del derrame mencionado. Se inicia tratamiento diurético, pero este debe ser suspendido cuandola paciente desarrolla disfunción renal importante; se drena el líquido con toracostomía, pero la pérdida devolumen adicional deteriora aún más la función renal, por lo que se decide realizar un shunt transyugularportosistémico (TIPS). Se logra disminuir la presión portal y el nivel de líquido ascítico y el derrame pleuraldisminuyen progresivamente. En una revisión posterior de la paciente y de su seguimiento radiológico no seregistró reaparición de los síntomas ni del derrame pleural o de ascitis.

Hepatic hydrothorax is a rare complication that occurs in patients with liver cirrhosis. We report the caseof a patient with NASH cirrhosis and evidence of portal hypertension who was admitted to the emergencydepartment with coughing and chest pain. Transudative pleural effusions (according to Light’s criteria) werefound in association with ascites, but no cardiac cause, pleural effusion or pulmonary effusion could be found.Treatment with diuretics was begun, but was suspended because the patient developed signifi cant renal dysfunction.Fluid was drained with a thoracostomy but additional loss of fl uid led to further deterioration of renalfunction. It was decided to insert a transjugular portosystemic shunt (TIPS) to signifi cantly decrease portalpressure and to progressively decrease ascitic fl uid and pleural effusion. A subsequent review of the patientand radiological follow-up found no recurrence of symptoms, pleural effusion or ascites.
