Vascular loops mimicking herniated lumbar discs: fair warning.

The authors report their experience with twenty-one consecutive patients who presented with symptoms and imaging characteristics of a herniated lumbar disc; of whom, at the time of surgery had a vascular loop instead. The procedure was performed on 14 women and seven men with a mean age of 39 years. Clinical complaints included lumbar aching with one limb overt radiculopathy in all patients; with additional sphincter dysfunction in two cases. Symptoms had developed within a mean period of three months. In all patients, the disc was exposed through an L5-S1 (n = 10); L4-L5 (n = 5) and L3-L4 (n = 6) open minimal laminotomy. In 16 patients, rather than a herniated disc they had a lumbar epidural varix, while an arterio-venous fistula was found in the remaining five cases. In all cases, the vascular disorder was resected and its subjacent disc was left intact. One patient had a postoperative blood transfusion. While the radiculopathy dysfunction improved in all patients, four patients reported lasting lumbar pain following surgery. The postoperative imaging confirmed the resolution of the vascular anomaly and an intact disc. The mean length of the follow-up period was 47 months. Either epidural varix or arterio-venous fistula in the lumbar area may mimic a herniated disc on imaging studies. With the usual technique they can be operated safely. Resection of the anomaly can be sufficient for alleviating radiculopathy symptoms.

A model for predicting poor survival in patients with cirrhosis undergoing portosystemic shunt embolization.

BACKGROUND AND AIM: Portosystemic shunt embolization (PSSE) is a promising treatment for hepatic encephalopathy (HEP) and gastric varix (GV) in cirrhotic patients with a spontaneous portosystemic shunt. However, PSSE may worsen portal hypertension causing hepatorenal syndrome, liver failure, and mortality. This study aimed to develop and validate a prognostic model that helps identify patients with a risk of poor short-term survival after PSSE. METHODS: We included 188 patients who underwent PSSE for recurrent HEP or GV at a tertiary center in Korea. To develop a prediction model for 6-month survival after PSSE, Cox proportional-hazard model was used. The developed model was validated in a separate cohort of 184 patients from two other tertiary centers. RESULTS: In multivariable analysis, the 1-year overall survival after PSSE was significantly associated with baseline levels of serum albumin, total bilirubin, and international normalized ratio (INR). We therefore developed the albumin-bilirubin-INR (ABI) score by assigning 1 point each for albumin < 3.0 g/dL, total bilirubin ≥ 1.5 mg/dL, and INR ≥ 1.5. Time-dependent areas under the curve of the ABI score for predicting 3-month and 6-month survival were 0.85 and 0.85 in the development cohort and 0.83 and 0.78 in the validation cohort, indicating good discrimination performance. The ABI score showed a better discrimination and calibration performance than the model for end-stage liver disease and the Child-Pugh scores, especially in high-risk patients. CONCLUSIONS: The ABI score is a simple prognostic model that helps decide whether to proceed with PSSE for the prevention of HEP or GV bleeding in patients with spontaneous portosystemic shunt.

Foetal death due to extensive extra-abdominal umbilical vein Varix with umbilical vein thrombosis: a case report.

BACKGROUND: Foetal anaemia and umbilical vein thrombosis are rare pregnancy complications that can increase the risk of perinatal adverse events, which, in severe cases, can lead to foetal death. During pregnancy, umbilical vein varix (UVV) commonly occurs in the intra-abdominal part of the umbilical vein and is associated with an increased risk of foetal anaemia and umbilical vein thrombosis. However, UVV occurring in the extra-abdominal part of the umbilical vein is rare, especially when accompanied by thrombosis. In this case report, we describe a rare case of an extensive extra-abdominal umbilical vein varix (EAUVV), which ultimately resulted in foetal death due to umbilical vein thrombosis. CASE PRESENTATION: In this report, we describe a rare case of an extensive EAUVV that was discovered at 25 weeks and 3 days of gestation. During the examination, there were no abnormalities in foetal haemodynamics. The estimated weight of the foetus was only 709 g. In addition to refusing to be hospitalized, the patient refused close monitoring of the foetus. As a result, we were limited to choosing an expectant therapy. The foetus died 2 weeks after diagnosis and was confirmed to have EAUVV with thrombosis after the induction of labour. CONCLUSION: In the case of EAUVV, lesions are extremely rare, and it is very easy for thrombosis to form, which may result in the death of the child. When determining the next step in the treatment of the condition, the degree of UVV, possible complications, gestational age, foetal haemodynamics, and other relevant factors are strongly connected to the clinical therapy decision, and these factors should be considered comprehensively when making a clinical decision. We recommend close monitoring with hospital admission (to facilities capable of handling extremely preterm foetuses) after variability in delivery for worsening haemodynamic status.

[Risk factors and construction of a nomogram model for cirrhotic portal vein thrombosis combined with esophagogastric variceal bleeding].

Objective: To investigate the risk factors and construct a nomogram model for predicting the occurrence of cirrhotic portal vein thrombosis in patients combined with esophagogastric variceal bleeding (EVB). Methods: Clinical data on 416 cirrhotic PVT cases was collected from the First Hospital of Lanzhou University between January 2016 and January 2022. A total of 385 cases were included after excluding 31 cases for retrospective analysis. They were divided into an esophagogastric variceal bleeding group and a non-esophagogastric variceal bleeding group based on the clinical diagnosis. The esophagogastric variceal group was then further divided into an EVB group and a non-bleeding group. All patients underwent gastroscopy, serology, and imaging examinations. The risk factors of PVT combined with EVB were identified by univariate analysis using SPSS 26. The prediction model of cirrhotic PVT in patients combined with EVB was constructed by R 4.0.4. The prediction efficiency and clinical benefits of the model were evaluated by the C-index, area under the receiver operating characteristic curve, calibration plots, and decision curve. The measurement data were examined by a t-test or Mann-Whitney U test. The counting data were tested using the χ(2) test or the Fisher exact probability method. Results: There were statistically significant differences in the etiology, Child-Pugh grade,erythrocyte count, hematocrit, globulin, and serum lipids between the esophageal and non-esophageal varices groups (P < 0.05). There were statistically significant differences in etiology, erythrocyte count, hemoglobin, hematocrit, neutrophil percentage, total protein, globulin, albumin/globulin, urea, high-density lipoprotein cholesterol, calcium, and neutrophil lymphocyte ratio (NLR) between the EVB and non-bleeding groups (P < 0.05). Multivariate logistic regression analysis showed that etiology (OR = 3.287, 95% CI: 1.497 ~ 7.214), hematocrit (OR = 0.897, 95% CI: 0.853 ~ 0.943), and high-density lipoprotein cholesterol (OR = 0.229, 95% CI: 0.071 ~ 0.737) were independent risk factors for cirrhotic PVT patients combined with EVB. The constructed normogram model predicted the probability of bleeding in patients. The nomogram model had shown good consistency and differentiation (AUC = 0.820, 95% CI: 0.707 ~ 0.843), as verified by 10-fold cross-validation (C-index = 0.799) and the Hosmer-Lemeshow goodness of fit test (P = 0.915). The calibration plot and the decision curve suggested that the prediction model had good stability and clinical practicability. Conclusion: The risk factors for EVB occurrence include etiology, erythrocyte, hemoglobin, hematocrit, percentage of neutrophils, total protein, globulin, albumin/globulin, urea, high-density lipoprotein cholesterol, calcium, and NLR in patients with cirrhotic liver. The constructed prediction model has good predictive value, and it can provide a reference for medical personnel to screen patients with high bleeding risk for targeted treatment.

Recurrent umbilical varix rupture with hemoperitoneum: a case report and review of literature.

BACKGROUND: Non-traumatic hemoperitoneum was a rare event with the risk of sudden death. Spontaneous rupture of hepatocellular carcinoma is the most intuitive diagnosis when hemoperitoneum occurs in cirrhotic patients who are not regularly followed up. However, other etiologies of hemoperitoneum, such as intra-abdominal varix rupture, should be kept in mind. CASE PRESENTATION: A 44-year-old man with alcoholic liver cirrhosis, Child-Pugh B was sent to our emergency department (ED) because of recurrent abdominal pain and hypovolemic shock. He had similar symptoms one month ago and was diagnosed as hepatocellular carcinoma (HCC) rupture with hemoperitoneum, therefore he underwent trans-arterial embolization (TAE). However, the follow-up magnetic resonance imaging (MRI) showed less possibility of hepatocellular carcinoma. Contrast enhanced abdominal computed tomography (CT) showed possible umbilical vein contrast agent extravasation. Exploratory laparotomy confirmed the diagnosis of rupture umbilical varix with hemoperitoneum. CONCLUSION: Although umbilical varix rupture is a rare cause of hemoperitoneum, it should be kept in mind in cirrhotic patients with unexplained hemoperitoneum.

The Risk of Cirrhosis and Its Complications Based on PNPLA3 rs738409 G Allele Frequency.

BACKGROUND: Data regarding the influence of patatin-like phospholipase domain-containing 3 (PNPLA3) polymorphism for patients with liver cirrhosis (LC) are scarce. OBJECTIVE: This study assesses the role of the PNPLA3 polymorphism for the development of LC and its complications by the findings of genetic examinations. METHODS: Patients with LC caused by virus (n = 157), alcohol (n = 104), nonalcoholic fatty liver disease (NAFLD) (n = 106), or autoimmune disease (n = 33) and without LC (n = 128) were enrolled. LC was composed of the presence and absence of complications, such as variceal bleeding, hepatic ascites, and hepatic encephalopathy. To assess the role of the PNPLA3 polymorphism, odds ratio (OR) for the rs738409 variant was calculated for the patients between (i) with LC and without LC in the entire cohort and (ii) the presence and absence of complications in the patients with LC. RESULTS: There was a significant difference among the patients without LC and those with alcohol, NAFLD-related LC in the frequency of G alleles (p < 0.001, both). According to complications of LC, the OR for NAFLD-related cirrhosis significantly increased in the presence of the two mutated alleles (OR = 3.165; p = 0.046) when the wild type was used as the reference. However, there were no significant risks for the complications in the virus and alcohol-related cirrhosis unless there was a presence of G alleles. CONCLUSION: The PNPLA3 polymorphism was associated with the risk of NAFLD-related LC and its complications.

Large intra-abdominal umbilical vein varix with absent ductus venosus: The undeniable etiology of fetal heart failure despite associated congenital heart disease.

Fetal intra-abdominal umbilical vein varix (IUVV) is one of the rare anomalies of the umbilical vessels that simulate a cystic structure but with a vascular nature. IUVV usually drains into IVC through ductus venosus (DV), with evidence of an increase in the cardiac preload in most cases. In the current report, we present a fetus with congenital heart disease; however, the association of large IUVV with DV agenesis and direct drainage into the heart resulted in a high output fetal heart failure.

Four cases of cervical varices without placenta praevia: Presentation, diagnosis, managements, and literature review.

Cervical varices are a rare condition characterized by recurrent antepartum hemorrhage and less than 20 cases were reported in the literature. It is usually associated with placenta previa. We herein describe four cases of cervical varices without placenta previa. Meticulous speculum examination, ultrasonography with Doppler and colposcopy are essential for establishing the diagnosis and assessing the extent of the cervical varix. We propose to classify it as the apparent external os type or ultrasonography-based endocervical type. Most cases presented in the literature were delivered by cesarean section. Nevertheless, one of our cases was a successful vaginal delivery. Our case illustrates that vaginal delivery is possible in isolated cervical varices. More case reports are needed to have a better understanding of this rare entity.

Partial anomalous pulmonary venous connection and pulmonary venous varix coexist in Turner syndrome: a case report.

Turner syndrome is a clinical syndrome caused by autosomal abnormalities in women. It is often accompanied by congenital cardiovascular malformations commonly including a bicuspid aortic valve malformation and aortic coarctation, but the presence of multiple pulmonary venous abnormalities is extremely rare. We present a 27-year-old woman who was diagnosed with Turner syndrome. She was revealed an anomalous right upper pulmonary venous connection, left upper pulmonary vein obstruction, and varicose vein malformations of the left pulmonary veins by a series of examination. Cardiac catheterisation and selective pulmonary angiography can further confirm the diagnosis, morphological characteristics, haemodynamic significance and provide a reference for the next step of treatment.

Recurrent epistaxis due to cribriform plate dural arteriovenous fistula: are they related? Should the treatment be from venous, pial or arterial side?

PURPOSE: Dural arteriovenous fistula (DAVF) of the anterior cranial fossa with cortical venous reflux is an aggressive neurovascular entity with a high rate of intracranial bleeding. Only two cases of anterior cranial fossa DAVF presenting with epistaxis alone have been reported. Endovascular approaches have emerged as the primary and safer treatment modality for most DAVFs. Certain fistulas are better treated with open surgical approaches and disconnection. CASE DESCRIPTION: A 55 years old male presented with the history of multiple episodes of severe epistaxis. Cerebral angiography revealed an anterior cranial fossa DAVF of the cribriform plate with cortical venous reflux and a venous varix. The patient was successfully managed with a bifrontal craniotomy and disconnection from the arterial side. CONCLUSION: Atypical or severe epistaxis may arise from a DAVF. Surgical arterial disconnection my be a curative treatment option.

Sublingual varicosity as a possible indicator of hypertension.

Oral varices are a common acquired vascular malformation that might be associated with several heart diseases. The aim of this study was to investigate whether an association exists between the severity of sublingual varices and stage of hypertension. Oral examinations were conducted, and the sublingual varicosity of 151 patients was categorized as grade 0, 1, or 2 based on severity. The blood pressure of the patients was measured and classified as normal, prehypertension, stage 1 hypertension, or stage 2 hypertension according to the guidelines of the National Heart, Lung, and Blood Institute. Pearson chi-square test, linear-by-linear association, and logistic regression were used for data analysis. Of 151 patients, 91 (60.3%) had sublingual varices, with 68 (45.0%) having grade 1 varicosity and 23 (15.2%) having grade 2. Sublingual varices were seen most frequently (84.4%) in patients older than 60 years. The frequency of hypertension (stage 1 or 2) among the sample was found to be 24.5%. The Pearson chi-square test showed a positive correlation between hypertension and sublingual varicosity (P < 0.0001; γ = 0.499). Logistic regression showed that the risk of hypertension in patients with grades 1 and 2 sublingual varicosity was 2.53 and 7.57 times greater, respectively, than that in patients with grade 0. In addition, sublingual varicosity (grade 1 or 2) was 2.32 times more frequent in men than in women (P = 0.022; 95% CI = 1.12-4.79) and 3.55 times more frequent in smokers than in nonsmokers (P = 0.003; 95% CI = 1.01-1.06). Therefore, sublingual varicosity may be a sign of hypertension.

Incidence, risk factors, and outcomes of jejunal varix of the afferent loop after pancreatoduodenectomy.

BACKGROUND: Jejunal varix is a concerning late complication after pancreatoduodenectomy (PD) due to the risk of recurrent and intractable bleeding. Our aim was to investigate the incidence, risk factors, and outcomes of jejunal varix after PD. METHODS: A total of 709 patients who underwent PD between 2007 and 2017 were included. Preoperative and postoperative CT images were reviewed to evaluate the development of portal vein (PV) stenosis (≥50%) and jejunal varices. RESULTS: Jejunal varix developed in 83 (11.7%) patients at a median of 12 months after PD. Eighteen (21.7%) patients experienced variceal bleeding. PV stenosis (P < 0.001; odds ratio [OR] 33.2, 95% confidence interval [CI] 15.6-66.7) and PV/superior mesenteric vein resection (P = 0.028; OR 2.3, 95% CI 1.1-4.7) were independent risk factors for jejunal varix. Of the nine patients who underwent stent placement for PV stenosis before the formation of jejunal varices, none experienced variceal bleeding. By contrast, 18 (27.3%) of the 135 patients without PV stent placement experienced at least one episode of variceal bleeding. CONCLUSIONS: The incidence of jejunal varix was substantial after PD. PV stenosis was a strong risk factor for jejunal varix. Early PV stent placement and maintaining stent patency could reduce the risk of variceal bleeding in patients with PV stenosis.

[Vortex vein varix (clinical observations)]. / Varikoznoe rasshirenie vortikoznykh ven (klinicheskie nablyudeniya).

Varix of the vortex vein ampulla is a rare benign condition that has clinical similarities to more concerning choroidal lesions that pose a threat to vision, in particular choroidal melanoma. The article describes two clinical cases, one of which is unique due to the combination of bilateral lesion and the presence of multiple varices in one eye. A brief review of the literature on this condition is also provided.

Sinistral Portal Hypertension Prediction During Pancreatoduodenectomy With Splenic Vein Resection.

BACKGROUND: Pancreaticoduodenectomy with porto-mesenterico-splenic confluence resection can cause sinistral portal hypertension (SPH), which may lead to gastrointestinal bleeding. Nevertheless, it remains difficult to predict SPH development during surgery. The aim of this study is to assess the feasibility of measuring splenic vein (SV) pressure to predict SPH. METHODS: The patients who underwent pancreaticoduodenectomy with porto-mesenterico-splenic confluence resection between January 2016 and December 2017 were included in this study. SV pressure was measured before SV clamping (SVP1) and after SV clamping (SVP2). SPH was defined as varicose vein formation detected by follow-up computed tomography. Incidence of SPH was assessed in patients who had no SV drainage after surgery. RESULTS: SV pressure was measured in 41 patients. Among them, 24 had no SV drainage (13 patients had occluded SV reconstruction, and 11 had SV ligation without an attempt at reconstruction) and were included for the analysis. SPH was observed in 16 of 24 patients (67%). The median ΔSVP (SPV2-SVP1) in patients with SPH was higher than that in patients without SPH (13.5 mmHg versus 7.5 mmHg, P = 0.0237). Most patients with SVP2 >20 mmHg (12/14 [86%]) or ΔSVP >10 mmHg (10/11 [91%]) developed SPH. CONCLUSIONS: For the patients with SV resection, high SV pressure after clamping (≥20 mmHg) and a large SV pressure difference (≥10 mmHg) before and after clamping are feasible indication criteria for SV reconstruction to prevent SPH.

Restoration of portal flow with varix in liver transplantation for patients with total portal vein thrombosis: An effective strategy in the largest center experience.

INTRODUCTION: Postoperative complications and worse prognosis still burden liver transplantations (LT) with complex portal vein thrombosis (CPVT). When an engorged left gastric vein (LGV) is present, the portal inflow is restorable with an anastomosis between the graft portal vein and the LGV of the recipient. We analyzed short- and long-term results of this procedure in 12 LT with CPVT. METHODS: Between 2005 and 2019, 55 patients with CPVT underwent LT. We applied this technique in 12 patients. In six cases, we placed a vascular graft to obtain a tension-free structure. We evaluated patency, short- and long-term results. RESULTS: No intraoperative complication was observed. The median duration of LT, blood transfusion, deceased donor age, and MELD score of the recipients were 7 h, 1250 mL, 72 years, and 19. Seven patients were affected by hepatocellular carcinoma. No major complications or PVT recurrence were observed. One patient required a liver re-transplantation for primary non-functioning syndrome. The mean hospital stay was 20 days. The actuarial patient survival was 85% with a mean FU of 4 years. The two late deaths were due to hepatocellular carcinoma recurrence and sepsis for cholangitis. CONCLUSIONS: This technique in presence of both CPVT and engorged LGV is feasible and safe for patients, with good short- and long-term results.

The spontaneous resolution of a vortex vein varix: case report.

BACKGROUND: The natural course of a vortex vein varix, though not well understood, has been known to remain stable. However, here we report a novel case of a vortex vein varix that resolved after an extended period of monitoring. CASE PRESENTATION: An asymptomatic 96-year-old Caucasian man was found to have a vortex vein varix. At his previous examination 13 months prior, his fundus was normal. At 13 months of observation, his vortex vein varix become clinically undetectable. Further follow-up confirmed continued absence of the varix. CONCLUSION: This case demonstrates the development then clinical resolution of a vortex vein varix with no clear identifiable factors for its evolution. This case is novel and offers new insight into the natural history of some vortex vein varices, implicating venous congestion as an instigator and venous collateralization as its alleviator, suggesting that vortex vein varices are likely more common than previously reported since some may be temporary and under-identified.

Orbital Compartment Syndrome and Irreversible Blindness Related to Orbital Varix Thrombosis: A Case Report.

BACKGROUND: Orbital compartment syndrome (OCS) is an ocular emergency that can severely threaten the visual potential. The most common etiologies include facial trauma-related orbital wall fractures and postoperative bleeding within the orbit. Nontraumatic cases were also reported sporadically, although they are rare. The orbital volume limits the compliance to expand when space-occupying lesions develop. Both direct compression of the optic nerve and depleted perfusion from elevated intraorbital pressure subsequently lead to ischemic optic neuropathy and vision loss. CASE REPORT: A 74-year-old man experienced headache, bulging left eye, dull pain, vision loss, nausea, and vomiting within 1 day. Computed tomography and magnetic resonance imaging revealed a heterogeneous mass extending from the orbital apex and connected with the ophthalmic vein. Lateral canthotomy and cantholysis were performed at bedside for emergent orbital decompression. The proptosis and pain relieved after surgery, but visual loss remained irreversible. Surgical exploration was conducted and pathology proved the diagnosis of varix of the ophthalmic vein with thrombosis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Clinicians should be aware of the presentation of OCS and perform timely orbital decompression, which could reverse visual impairment. These patients might also benefit from immediate consultants with ophthalmologists and radiologists.

Massive Extra-Abdominal Umbilical Vein Varix: A Case Report.

Umbilical vein varices are rare umbilical cord anomalies that typically occur intra-abdominally. Extra-abdominal umbilical vein varices are exceedingly rare and usually diagnosed postnatally on gross pathologic examination. Umbilical vein varices have been associated with increased risk of fetal anemia, cardiac abnormalities, and intrauterine fetal demise. This case report discusses a patient who presented with a massive extra-abdominal umbilical vein varix, whose infant was ultimately delivered due to fetal distress and died in the neonatal period. This report also discusses associated fetal conditions and guidelines for antenatal testing and surveillance of known umbilical vein varices.

Venous Cerebral Infarction Due to Thrombosis of an Isolated Intraventricular Cerebral Varix: A Case Report.

OBJECTIVES: An isolated intraventricular cerebral varix is a rare entity. Although it is generally asymptomatic, there have been reports of symptomatic cases. Here, we report a case of right hemiplegia and aphasia due to venous infarction caused by thrombosis of the intraventricular varix. CASE PRESENTATION: A 79-year-old woman presented with right-sided hemiplegia and aphasia accompanied by conjugate eye deviation to the left. She had a history of hypertension, dyslipidemia, and asymptomatic isolated cerebral varix located in the left lateral ventricle. Blood analysis indicated no abnormalities in coagulation or fibrinolysis. Plain head computed tomography showed an intraventricular varix in the form of a high-density mass, indicating acute phase thrombosis, and contrast-enhanced computed tomography depicted a filling defect in the varix. In addition, fluid-attenuated inversion recovery imaging showed hyperintense lesions in the deep white matter of the frontal-parietal lobe, indicating venous infarction due to occlusion of the varix of the thalamostriate vein. Glycerol and prophylactic levetiracetam were administered, and she was transferred to another hospital for rehabilitation 23 days after treatment initiation. CONCLUSION: This is the first reported case in which a typically asymptomatic condition, intraventricular cerebral varix, caused venous infarction due to thrombosis and occlusion of the varix of the thalamostriate vein. Careful selection of the treatment strategy is required on a case-by-case basis because an intraventricular varix can cause both bleeding and infarction, which are treated differently.

Clinical outcomes of sedation during emergency endoscopic band ligation for variceal bleeding: Multicenter cohort study.

BACKGROUND AND AIMS: Few studies have directly compared the efficacy of sedated- and un-sedated endoscopic variceal ligation (EVL) for acute variceal bleeding. We aimed to determine whether sedation during EVL in patients with variceal bleeding is safe and effective. METHODS: We analyzed data from patients who underwent EVL for acute variceal bleeding according to sedation in six hospitals of Hallym University Medical Center. The primary endpoint was treatment failure, defined as a failure to control bleeding, death during EVL, or rebleeding within 5 days. Secondary endpoints included the procedure time, adverse events, and 30-day mortality. RESULTS: Of 1,300 patients who were included, only 430 (33.1%) received sedation during EVL. Propofol alone was used for sedation in 85% of sedated-EVLs. The mean procedure time in the sedation group was shorter than that of the non-sedation group (12.4 ± 9.5 min versus 13.8 ± 9.4 min, P = 0.010). The proportion of treatment failure did not differ between the groups (7.4% versus 9.1%, P = 0.374). In the multivariable analysis, an AIMS65 score ≥2 and blood transfusion within 72 hours were associated with treatment failure of EVL; however, the use of sedation was not (odds ratio [95% confidence interval (CI)] = 0.96 [0.60-1.51]). Adverse events during EVL and hepatic encephalopathy did not differ between the two groups. Sedation also did not affect the 30-day mortality (hazard ratio [95% CI] = 0.99 [0.66-1.47]). CONCLUSION: Sedation reduced the procedure time of EVL. Sedation is safe to use during EVL for variceal bleeding in patients with cirrhosis.
