RESUMEN

BACKGROUND: Porto-sinusoidal vascular disease (PSVD) and portal vein thrombosis (PVT) are causes of portal hypertension characterized respectively by an intrahepatic and a pre-hepatic obstacle to the flow in the portal system. As PVT may be a consequence of PSVD, in PVT patients at presentation, a pre-existing PSVD should be suspected. In these patients the identification of an underlying PSVD would have relevant implication regarding follow-up and therapeutic management, but it could be challenging. In this setting ultrasonography may be valuable in differential diagnosis. The aim of the study was to use ultrasonography to identify parameters to discriminate between PSVD and "pure" PVT and then to suspect PVT secondary to a pre-existing PSVD. METHODS: Fifty-three patients with histologically proven PSVD and forty-eight patients affected by chronic PVT were enrolled and submitted to abdominal ultrasonography with elastography by acoustic radiation force impulse (ARFI). RESULTS: ARFI was higher and superior mesenteric vein (SMV) diameter was wider in PSVD patients than in PVT patients. Thus, a prognostic score was obtained as linear combinations of the two parameters with a good discrimination capacity between PSVD and PVT (the area under the curve = 0.780; 95% confidence interval: 0.690-0.869). CONCLUSIONS: A score based on ARFI and SMV diameter may be useful to suspect an underlying PSVD in patients with PVT and to identify a subgroup of patients to be submitted to liver biopsy.

RESUMEN

Sustained virological response (SVR) obtained with interferon (IFN) or with direct-acting antivirals (DAAs) is commonly followed by response of hepatitis C virus (HCV)-associated mixed cryoglobulinemia vasculitis (MCV), but relapse of MCV despite SVR has been reported in several patients after DAAs and rarely after IFN. Since relapses could have been overlooked in studies with IFN, we retrospectively compared the outcomes of MCV in SVR patients treated with DAAs (n = 70) or IFN (n = 39) followed-up, respectively, for 30.5 (range 11-51) or 48 months. Groups were comparable for demographics and clinics and response rates of MCV were similar (92% and 86%); however, DAA-treated patients less efficiently reduced cryoglobulins (P = .006) and circulating B-cell clones (P = .004), and had more frequently relapses of MCV (18% vs 3%, P = .028) and need for rituximab therapy (P = .01). Although largely inferior on an intention-to-treat basis, IFN may be superior to DAAs on clinico-immunological outcomes possibly owing to its antiproliferative activity.

RESUMEN

OBJECTIVE: The use of minimally invasive or transcatheter interventions rather than standard full sternotomy operations to treat tricuspid valve (TV) disease is increasing. The debate however is still open regarding venous drainage management during cardiopulmonary bypass (CPB) and wheatear or not superior and inferior vena cava should be occluded during the opening of the right atrium to avoid air entrance in the venous line. The aim of the present study is to report operative outcomes and midterm follow-up results of minimally invasive TV surgery performed without caval occlusion. METHODS: A retrospective outcome evaluation from institutional records was performed with prospective data entry. Considered were consecutive patients who underwent right mini-thoracotomy TV surgery isolated or combined with mitral valve surgery during the period from June 2013 to February 2020. A telephone and echocardiographic follow-up was performed. RESULTS: During the study period, 68 consecutive patients underwent minimally invasive TV surgery without occlusion of cava veins. The mean age was 69 ± 14 years and 48 (70%) were female. All operations were performed safely without air-lock during CPB. A perioperative cerebral stroke occurred in one patient. The survival at a 5- and 8-year follow-up was 100% and 79%, respectively. No severe tricuspid regurgitation was evident at echocardiographic follow-up. CONCLUSION: Our results show that performing tricuspid surgery without caval occlusion is safe. The air was captured by the active vacuum drainage system without causing damage. Midterm follow-up data confirm that a minimally invasive approach does not alter the quality of surgery.

RESUMEN

Rectal prolapse is a disorder in which the rectum protrudes from the anal canal. Solitary rectal ulcer may coexist. Both conditions have been associated with chronic constipation and excessive straining during defecation. Rectal prolapse has been rarely reported in women suffering from anorexia nervosa. Lack of rectal support because of loss of ischiorectal fat has been proposed as one of the possible mechanisms in this condition, together with chronic constipation and abuse of laxative. We report the case of an anorexic woman with a severe rectal prolapse and bleeding requiring urgent Altmeier's procedure. Surgery was complicated by dehiscence of the anastomosis and volvulus, requiring ileostomy and laciniae debridement. Pathological analysis of all the surgical samples taken from different abdominal sites highlighted changes in the visceral adipose tissue consisting in nodular aggregates of small adipocytes dispersed in a myxoid matrix surrounding blood vessels within abundant fibrosis. The morphologic features resemble those observed in primordial fetal fat and are comparable to those observed in cancer associated cachexia. The diffuse myxoid degeneration of visceral adipose tissue may play a role in the pathogenesis of rectal prolapse in patients with anorexia nervosa. Besides starvation, the mechanism sustaining myxoid degeneration of the adipose tissue is not entirely clear. Whenever possible improving nutritional and clinical conditions should be ideal before any surgical approach.

RESUMEN

Small hepatic veins Budd-Chiari syndrome is a rare disorder characterized by hepatic venous outflow obstruction limited to the small intrahepatic veins, with normal appearance of the large hepatic veins at imaging. In this case only a liver biopsy can demonstrate the presence of a small vessels outflow block. Paroxysmal nocturnal haemoglobinuria (PNH) is one of the most severe acquired thrombophilic state and represents one of the main aetiological factors of Budd-Chiari syndrome. In patient affected by PNH with liver impairment and/or ascites, Budd-Chiari syndrome must be always taken into consideration and, if necessary, a liver biopsy performed to exclude the small hepatic veins involvement. We report a case of small hepatic veins Budd-Chiari syndrome secondary to paroxysmal nocturnal haemoglobinuria.

RESUMEN

BACKGROUND & AIMS: Hepatitis C virus (HCV)-related mixed cryoglobulinaemia vasculitis (MCV) is characterized by the expansion of rheumatoid factor-producing B-cell clones. The aim of this study was to assess whether B-cell clones may persist in these patients after the clearance of the virus with antiviral therapy, and whether their persistence influences clinical outcomes. METHODS: Forty-five HCV-cured MCV patients were followed up for a median of 18.5 (range 9-38) months after the clearance of HCV. Circulating B-cell clones were detected using flow cytometry either by the skewing of kappa/lambda ratio or by the expression of a VH 1-69-encoded idiotype. RESULTS: The clinical response of vasculitis was 78% complete, 18% partial and 4% null. However, cryoglobulins remained detectable in 42% of patients for more than 12 months. Circulating B-cell clones were detected in 18 of 45 patients, and in 17 of them persisted through the follow-up; nine of the latter patients cleared cryoglobulins and had complete response of vasculitis. Several months later, two of these patients had relapse of MCV. CONCLUSIONS: B-cell clones persist in MCV patients long after HCV infection has been cleared but halt the production of pathogenic antibody. These 'dormant' cells may be reactivated by events that perturb B-cell homeostasis and can give rise to the relapse of cryoglobulinaemic vasculitis.

RESUMEN

INTRODUCTION AND AIM: Cirrhotic patients with hepatitis C virus genotype 3 infection show unsatisfactory outcomes after 12 weeks' treatment with direct antiviral agents. The National Italian Drug Agency allows 24 weeks of therapy in difficult-to-treat patients, including genotype 3 cirrhotics. Aim of this study was to evaluate efficacy and safety of a 24-week course of sofosbuvir plus daclatasvir±ribavirin in this population. MATERIALS AND METHODS: 106 consecutive cirrhotics (70.8% males, mean age 55.3±7.6 years) in 8 tertiary hepatology centers received sofosbuvir plus daclatasvir for 24 weeks. Ribavirin was administered in 85 (80.2%) based expected tolerability, at a mean dose of 964±202mg/day. Baseline Child-Pugh class was A 91.5%, B 6.6%, C 1.9%; mean baseline MELD was 8.5±2.7. RESULTS: All patients completed 12-week follow-up post-treatment, and 104 (98.1%) obtained sustained virological response (100% in ribavirin -treated patients vs. 90.4% without ribavirin; p=0.04). No worsening in renal and liver function was observed, no serious adverse events occurred. Two virological failures showed resistance associated variants (Y93H and S282T). CONCLUSION: An extended 24-week treatment with sofosbuvir plus daclatasvir+ribavirin obtained 100% efficacy in genotype 3 hepatitis C cirrhosis, with very limited side effects. The role of ribavirin seems crucial in this setting and should be administered if clinically feasible.

RESUMEN

Risk of hepatocellular carcinoma (HCC) in hepatitis C virus cirrhotic patients treated with direct-acting antiviral agents (DAA) is still debating. We investigated it in a large cohort. The cohort comprised 1045 cirrhotic patients who completed treatment with DAA, with a median follow-up of 17.3 months after end of treatment (EOT), including 943 patients without history of HCC and 102 previously treated for HCC. The majority were men (59.9%), with compensated cirrhosis (88.8%), genotype 1b (44.7%). Univariate, multivariate analysis and Kaplan-Meier curves were performed to detect predictors of HCC in patients with and without reduction in alpha-fetoprotein (AFP) during treatment. SVR12 was 95.6%. HCC developed in 95 (9.9%), including 54 of 943 (5.7%) occurrent and 41 of 102 (39%) recurrent tumours. De novo were more often unifocal (P = 0.01) and curable (P = 0.03). AFP decreased from 16.1 ± 36.2 mg/dL (baseline) to 11.4 ± 55 mg/dL (EOT). At univariate analysis, predictors were a previous HCC, older age, higher model for end-stage liver disease, prolonged INR, lower platelets, baseline and EOT AFP, virological failure and no reduction in AFP during treatment. Kaplan-Meier curves showed lower incidence of HCC in patients showing any reduction in AFP (P = 0.001). Those with AFP <6 ng/mL had the lowest risk (P = 0.0002). At logistic regression, platelets (P = 0.009, OR 0.99 CI: 0.99-1.00), previous HCC (P < 0.000 01, OR: 10.76, 95% CI: 5.89-19.34) and no reduction in AFP during treatment (P = 0.0005, OR: 2.98, CI: 1.60-5.54) were independent predictors of HCC. In conclusion, risk of HCC after DAA treatment remains substantial. It is higher among patients with previous HCC, low platelets and without reduction in AFP during treatment.

RESUMEN

BACKGROUND: Management of chronic hepatitis C (CHC) has significantly accelerated in the last few years. Currently, second generation direct acting antivirals (DAAs) promise clearance of infection in most of patients. Here we present the results of the first analysis carried out on data of Lazio clinical network for DAAs. METHODS: The study was designed as a multicenter cohort: a) to assess the evolution of treatment during the first 24 months of the activity of the Clinical Network; b) to report overall efficacy of treatments; c) to analyze potential factors associated with lack of virological response at 12 weeks after therapy (SVR12); d) to evaluate the variation of ALT at baseline and 12 weeks after therapy in those who achieved SVR12 in comparison to those who did not. Analyses of efficacy were carried out with multilevel mixed effect logistic regression model. ALT temporal variation was assessed by mixed effect model mixed models with random intercept at patient's level and random slope at the level of the time; i.e. either before or after therapy. RESULTS: Between 30 December 2014 and 31 December 2016 5279 patients started a DAA treatment; of those, 5127 (in 14 clinical centers) had completed the 12-week follow-up. Overall proportion of SVR12 was 93.41% (N = 4780) with no heterogeneity between the 14 clinical centers. Interruption as the consequence of severe side effect was very low (only 23 patients). Unadjusted analysis indicates that proportion of SVR12 significantly changes according to patient's baseline characteristics, however after adjusting for potential confounders only adherence to current guidelines, stage of liver diseases, gender, transplant and HIV status were independently associated with the response to therapy. Analysis of ALT temporal variation showed that ALT level normalized in most, but not, all patients who achieved SVR12. CONCLUSION: Our study confirmed the extraordinary efficacy of DAAs outside clinical trials. The advantage of DAAs was particularly significant for those patients who were previously considered as difficult-to-treat and did not have treatment options before DAAs era. Intervention based on network of select centers and prioritization of patients according to diseases severity was successful. Further studies are needed to establish whether clearance of HCV after DAAs therapy can arrest or even revert liver fibrosis in non-cirrhotic patients and/or improve life quality and expectancy in those who achieve SVR12 with cirrhosis.

RESUMEN

BACKGROUND AND AIM: Spleen and liver stiffness (LS) measured by acoustic radiation force impulse (ARFI) imaging has been shown to be useful in identifying patients with portal hypertension. The study aims to establish if the modification of portal pressure induced by a transjugular intrahepatic portosystemic shunt (TIPS) parallels the modification of spleen or LS measured by ARFI in order to understand if ARFI may be used to monitor the modification of portal pressure in patients with cirrhosis. METHODS: Thirty-eight patients with severe portal hypertension underwent LS and spleen stiffness (SS) before TIPS and 1 week after TIPS. Portal atrial gradient (PAG) was measured before and after the shunt opening. RESULTS: Portal atrial gradient decreased significantly from 19.5 to 6 mmHg (P < 0.001). SS decreased significantly after TIPS (pre-TIPS 3.7 m/s vs post-TIPS 3. 1 m/s; P < 0.001), and LS was also significantly modified by TIPS (pre-TIPS 2.8 m/s vs post-TIPS 2.4 m/s; P = 0.003). PAG and SS values measured before and after TIPS were significantly correlated (r = 0.56; P < 0.001); on the other hand, PAG and LS were not (r = 0.19; P = 0.27). Two patients developed a persistent hepatic encephalopathy refractory to medical treatment and were submitted to the reduction of the stent diameter. The modification of SS was parallel to the modification of PAG. CONCLUSION: Spleen stiffness is superior to LS in detecting the modification of portal pressure induced by TIPS. This makes SS a potential non-invasive method to monitor the modification of portal hypertension. Further investigations are needed to establish applicability and clinical utility of this promising tool in the treatment of portal hypertension.

RESUMEN

Prognostic ability of BCLC-B Subclassification in Patients with Hepatocellular Carcinoma Undergoing Transarterial Chemoembolization Background and aims. A subclassification system for intermediate hepatocellular carcinoma (HCC) was recently proposed to optimize treatment allocation. The aim of this study was to assess the prognostic ability of that substaging proposal. PATIENTS AND METHODS: This is a retrospective multicenter cohort study including patients with intermediate HCC treated with transarterial chemoembolization (TACE). Predictors of survival were identified using the Cox proportional regression model. RESULTS: 289 Barcelona Clinic Liver Cancer (BCLC) B patients were included. Median overall survival of the whole cohort was 23 months (C.I. 95% 20.2- 25.8). Child A status (H.R. 1.35, C.I. 95% 1.02-1.78) and tumour burden beyond the up-to-seven criterion (H.R. 1.39, C.I. 95% 1.07- 1.80) were independent prognostic factors for overall survival on multivariate analysis. Analysis of the substages showed that median survival was 33.0 months for B1 stage (n = 81), 20.8 months for B2 stage (n = 106), 16.1 months for B3 stage (n = 24), 22.2 months for B4 stage (n = 42) and 15.0 months for quasi-C stage (n = 36). Regarding the discriminatory ability of the substaging proposal, the log rank test showed a significant survival difference for B1vs. B4 (p = 0.003) and B1 vs. Quasi-C (p = 0.039) and a trend for B1 vs. B2 (p = 0.05) and B1 vs. B3 (p = 0.05). CONCLUSIONS: Apart from substage B1, BCLC-B subclassification does not discriminate perfectly patients treated with TACE. Also some patients in substage B4 can benefit from TACE.

RESUMEN

Hepatitis C virus (HCV)-associated mixed cryoglobulinemia (MC) vasculitis commonly regresses upon virus eradication, but conventional therapy with pegylated interferon and ribavirin yields approximately 40% sustained virologic responses (SVR). We prospectively evaluated the efficacy and safety of sofosbuvir-based direct-acting antiviral therapy, individually tailored according to the latest guidelines, in a cohort of 44 consecutive patients with HCV-associated MC. In two patients MC had evolved into an indolent lymphoma with monoclonal B-cell lymphocytosis. All patients had negative HCV viremia at week 12 (SVR12) and at week 24 (SVR24) posttreatment, at which time all had a clinical response of vasculitis. The mean (±standard deviation) Birmingham Vasculitis Activity Score decreased from 5.41 (±3.53) at baseline to 2.35 (±2.25) (P < 0.001) at week 4 on treatment to 1.39 (±1.48) (P < 0.001) at SVR12 and to 1.27 (±1.68) (P < 0.001) at SVR24. The mean cryocrit value fell from 7.2 (±15.4)% at baseline to 2.9 (±7.4)% (P < 0.01) at SVR12 and to 1.8 (±5.1)% (P < 0.001) at SVR24. Intriguingly, in the 2 patients with MC and lymphoma there was a partial clinical response of vasculitis and ∼50% decrease of cryocrit, although none experienced a significant decrease of monoclonal B-cell lymphocytosis. Adverse events occurred in 59% of patients and were generally mild, with the exception of 1 patient with ribavirin-related anemia requiring blood transfusion. CONCLUSION: Interferon-free, guideline-tailored therapy with direct-acting antivirals is highly effective and safe for HCV-associated MC patients; the overall 100% rate of clinical response of vasculitis, on an intention-to-treat basis, opens the perspective for curing the large majority of these so far difficult-to-treat patients.

RESUMEN

OBJECTIVES: To investigate the expression of a VH1-69-encoded idiotype, and the phenotypic and functional features of monoclonal B-cells from patients with type II mixed cryoglobulinaemia (MC) secondary to chronic hepatitis B virus (HBV) infection. METHODS: B-cell immunophenotype and expression of a VH1-69-encoded idiotype were investigated by flow cytometry. B-cell proliferative responses to stimuli were investigated by the CFSE dilution assay. RESULTS: Two out of five patients with chronic HBV studied had massive monoclonal expansion of VH1-69-expressing B-cells. These cells had the peculiar CD21(low) phenotype and low responsiveness to stimuli typical of the VH1-69-expressing B-cells commonly expanded in MC secondary to hepatitis C virus (HCV) infection. In both patients, anti-HBV therapy led to the regression of MC and of VH1-69+ B-cell expansion. CONCLUSIONS: VH1-69-encoded antibodies are known to preferentially recognise a variety of viral proteins including HCV E2, influenza A virus haemagglutinin and HIV gp41/gp120, and may serve as innate first line antiviral defense. Thus, like HCV, HBV may cause MC by protracted antigenic stimulation of VH1-69-expressing B-cells.

RESUMEN

BACKGROUND & AIMS: Environmental and genetic factors contribute to alcoholic cirrhosis onset. In particular, age at exposure to liver stressors has been shown to be important in progression to fibrosis in hepatitis C individuals. However, no definite data on the role of age at onset of at-risk alcohol consumption are available. Moreover, patatin-like phospholipase domain-containing protein 3 (PNPLA3) I148M (rs738409) variant has been associated with alcoholic cirrhosis, but only in cross-sectional studies. The aim of this study was to investigate the role of age at onset of at-risk alcohol consumption and PNPLA3 I148M variant on alcoholic cirrhosis incidence. METHODS: A total of 384 at-risk alcohol drinkers were retrospectively examined. The association among age at onset of at-risk alcohol consumption, PNPLA3 I148M variant and cirrhosis incidence was tested. RESULTS: A higher incidence of alcoholic cirrhosis was observed in individuals with an older (≥24 years) compared with a younger (<24) age at onset of at-risk alcohol consumption (P-value < 0.001). Moreover, PNPLA3 148M allele carriers showed an increased incidence of cirrhosis (P-value < 0.001). Both age at onset of at-risk alcohol consumption and PNPLA3 148M allele were independent risk factors for developing cirrhosis (H.R. (95% C.I.): 2.76 (2.18-3.50), P-value < 0.001; 1.53(1.07-2.19), P-value = 0.021 respectively). The 148M allele was associated with a two-fold increased risk of cirrhosis in individuals with a younger compared with an older age at onset of at-risk alcohol consumption (H.R. (95% C.I.): 3.03(1.53-6.00) vs. 1.61(1.09-2.38). CONCLUSIONS: Age at onset of at-risk alcohol consumption and PNPLA3 I148M genetic variant are independently associated with alcoholic cirrhosis incidence.

RESUMEN

OBJECTIVES: To prospectively compare the diagnostic performance of ultrasound (US), multidetector computed tomography (MDCT) and contrast-enhanced magnetic resonance imaging (MRI) in cirrhotic patients who were candidates for liver transplantation. METHODS: One hundred and forty consecutive patients with 163 hepatocellular carcinoma (HCC) nodules underwent US, MRI and MDCT. Diagnosis of HCC was based on pathological findings or substantial growth at 12-month follow-up. Four different image datasets were evaluated: US, MDCT, MRI unenhanced and dynamic phases, MRI unenhanced dynamic and hepatobiliary phase. Diagnostic accuracy, sensitivity, specificity, PPV and NPV, with corresponding 95 % confidence intervals, were determined. Statistical analysis was performed for all lesions and for three lesion subgroups (<1 cm, 1-2 cm, >2 cm). RESULTS: Significantly higher diagnostic accuracy, sensitivity and NPV was achieved on dynamic + hepatobiliary phase MRI compared with US, MDCT and dynamic phase MRI alone. The specificity and PPV of US was significantly lower than that of MDCT, dynamic phase MRI and dynamic + hepatobiliary phase MRI. Similar results were obtained for all sub-group analyses, with particular benefit for the diagnosis of smaller lesions between 1 and 2 cm. CONCLUSIONS: Dynamic + hepatobiliary phase MRI improved detection and characterisation of HCC in cirrhotic patients. The greatest benefit is for diagnosing lesions between 1 and 2 cm.

RESUMEN

Fibroblast growth factor 21 (FGF-21), previously recognized as a marker of liver damage and a potential drug target in non-alcoholic fatty liver disease (NAFLD), has unclear implications in hepatitis C virus (HCV) infections. This study aimed to investigate the relationship between FGF-21 levels and liver health in patients with HCV undergoing direct-acting antiviral (DAA) treatment. Forty-five patients were assessed for liver stiffness, blood chemistry, and other relevant metrics before and after achieving sustained viral response (SVR), defined as the absence of detectable HCV-RNA after 24 weeks of treatment. Post-treatment, all patients showed a decrease in liver stiffness and improved liver enzyme levels (AST and ALT), alongside an increase in FGF-21 levels. Interestingly, the increase in FGF-21 correlated negatively with liver stiffness but showed no correlation with hepatic steatosis. The observed elevation in FGF-21 levels at SVR following DAA therapy for chronic HCV infection can be attributed to the restoration of hepatic function, including its synthetic capabilities. Specifically, the mitigation of liver fibrosis post-HCV eradication is expected to lead to improvements in liver function, such as enhanced albumin and FGF-21 production. This improvement in synthetic function likely drives the increase in FGF-21 levels, rather than changes in liver fat content. We suggest a potential role of FGF-21 as a marker of fibrosis and hepatic cytotoxicity and as a drug target beyond NAFLD, to be confirmed by additional studies.

RESUMEN

(1) Background: We investigated, for the first time, whether dietary simple sugar intake affects MELD score changes over time in a cohort of cirrhotic liver transplant candidates. (2) Methods: the MELD score, dietary habits using a 3-day food diary, and visceral adipose tissue index (VATI) measured with CT scan were assessed in 80 consecutive outpatient cirrhotic patients at baseline, after counseling to follow current nutritional guidelines. The MELD score was reassessed after six months and the DELTA-MELD was calculated as the MELD at the second assessment minus the MELD at baseline. (3) Results: Compared with the baseline, the MELD score of cirrhotic patients at the end of the study was decreased, stable, or increased in 36%, 8% and 56% of patients, respectively. In separate multiple linear regression models, DELTA-MELD was positively and independently correlated with the daily intake of simple sugars expressed in g/kg body weight (p = 0.01) or as a percentage of total caloric intake (p = 0.0004) and with the number of daily portions of fruit, added sugar, jam, and honey (p = 0.003). These associations were present almost exclusively in patients with VATI above the median value. (4) Conclusions: In cirrhotic patients with high amounts of visceral adipose tissue the consumption of simple sugars and fructose should be limited to improve their clinical outcome.

RESUMEN

BACKGROUND: Liver involvement in adults with acute myeloid leukemia is uncommon. Most of the case reports describe acute liver failure or obstructive jaundice, while acute hepatitis is rarely mentioned. We report a patient with acute myeloid leukemia who presented with clinical, biochemical, and radiological signs of acute hepatitis that totally regressed after chemotherapy. CASE PRESENTATION: A 38-year-old Caucasian man presented with fever, cough, and mild fatigue. Laboratory workup showed anemia, thrombocytopenia, severe leukocytosis, transaminitis, and hyperbilirubinemia. Imaging of the abdomen (ultrasound and magnetic resonance) showed hepatomegaly, splenomegaly, upper limits portal veins diameters, increased thickness of the gallbladder wall, and significant abdominal lymph nodes. Peripheral blood smear and bone marrow evaluation were consistent with acute myeloid leukemia, and liver biopsy showed massive sinusoidal and portal infiltration by leukemic cells. After remission-inducing chemotherapy, there was complete normalization of liver function tests, and liver, spleen, and portal vein size. CONCLUSIONS: This case highlights the importance of taking acute myeloid leukemia into account as a possible cause of liver damage to make a rapid diagnosis and start appropriate treatment that may lead to hematological remission and hepatic dysfunction resolution.

RESUMEN

Reoperations for a dysfunctional mechanical aortic valve prosthesis are usually performed with a repeat sternotomy. Reopening the chest may be associated with a heart structure tear, bleeding, excessive transfusion, and a possible unfavorable outcome. Experience performing a redo aortic valve replacement with a minimally invasive approach and avoiding lysis of the pericardial adhesions is growing. We describe a redo aortic valve replacement procedure performed because of subvalvular pannus formation in a patient with a mechanical prosthesis. A partial J-shaped hemisternotomy at the 3rd intercostal space was performed; the ascending aorta was exposed and the valve was replaced with a sutureless bioprosthesis. The video tutorial shows the surgical approach, cardiopulmonary bypass solutions, and sutureless valve deployment.
