RESUMO

AIMS: Hereditary protein S (PS) deficiency is one of the natural anticoagulant deficiencies causing thrombophilia. We herein described a young male with recurrent deep venous thrombosis, who was diagnosed as type I PS deficiency with compound heterozygous mutations of PROS1 gene. We aimed to analyse the relationship between the genotype and phenotype detection and investigate the pathological mechanisms of PROS1 mutations causing PS deficiency. METHODS: Genetic analysis of PROS1 gene was carried out by direct sequencing. Thrombin generation potential and the inhibition function of thrombin generation by plasma PS were detected by thrombin generation test (TGT). The mRNA transcription level of mutant PS in vitro was measured by real-time PCR, while the protein level was evaluated by western blot and ELISA. Cellular distribution of the protein was further analysed by immunofluorescence. RESULTS: Compound heterozygous mutations (PROS1 c.1551_1552delinsG, p.Thr518Argfs*39 and PROS1 c.1681C>T, p.Arg561Trp) were identified in the propositus, and the former one was a novel small indel mutation. TGT results showed impaired inhibition of thrombin generation with the addition of activated protein C in his parents with certain heterozygous mutations. In vitro expression study, p.Thr518Argfs*39 mutant produced truncated protein retained in the cytoplasm, while p.Arg561Trp mutant partially affected the secretion of PS. Both mutations are located in C-terminal sex hormone-binding globulin (SHBG)-like domain of PS. CONCLUSIONS: Compound heterozygous mutations identified in the study have strong detrimental effect, causing severe type I PS deficiency in the propositus. SHBG-like domain of PS might play an important role in PS secretion system.

RESUMO

RATIONALE: Contrast-enhanced computed tomographic venography (CTV) or magnetic resonance venography (MRV) are usually used to detect May-Thurner syndrome (MTS). However, both are associated with contrast-induced nephrotoxicity. For patients who cannot receive contrast media, non-contrast-enhanced MRV using three-dimensional (3D) turbo spin-echo (TSE) is considered an alternative. We report a case of MTS to describe its clinical utility and advantages. PATIENT CONCERNS: A 49-year-old male experienced isolated left leg swelling and pain for half a month. He had a history of chronic renal insufficiency that made contrast-enhanced imaging studies inadequate. DIAGNOSES: A lower extremity venous Duplex scan showed a thrombus extending from the left distal femoral vein to the popliteal vein with valvular reflux, consistent with infrainguinal deep vein thrombosis (DVT). The suprainguinal DVT was evaluated by non-contrast-enhanced MRV. The results showed sandwich external compression of the left common iliac vein between the right common iliac artery and lumbar vertebrae, consistent with DVT of the left common iliac vein caused by MTS. INTERVENTIONS: The patient received angioplasty with the implantation of a balloon-expandable stent over the left common iliac vein. OUTCOMES: Excellent recanalization of the left iliac vein was noted postoperatively. LESSONS: In the evaluation of suprainguinal venous lesions, non-contrast-enhanced MRV presents the venous structure alone at high resolution without the accompanying arterial structure, which makes it an excellent diagnostic imaging tool for MTS. These findings indicate that non-contrast-enhanced MRV could be useful for detecting systemic venous pathologies in patients with renal insufficiency.

RESUMO

OBJECTIVES: Systemic therapy aimed at suppressing the diffuse inflammation in the vessel wall is the major treatment modality for venous thrombosis in Behçet's syndrome (BS). Endovascular and/or surgical interventions are also used. We here report five patients who were referred to our clinic after having such interventions and also present a literature review to assess the outcome of invasive procedures for venous thrombosis in BS. METHODS: Our patients were presented and a literature search for endovascular and/or surgical interventions in Pub-Med was performed. Recanalisation, reocclusion or other complications were assessed as outcomes. RESULTS: Five BS patients with lower extremity thrombosis were referred to our clinic with post thrombotic syndrome due to incomplete recanalisation or infectious complication after endovascular interventions. Twenty-one articles reporting on 36 patients were found suitable for review. There were totally 21 lower extremity venous intervention cases, 14 of which had failure such as complication, reocclusion or incomplete recanalisation. Reocclusions occurred in 10 patients and reinterventions to 8 of them could restore flow only in 4 cases. Ileal infarct and vena cava wall-duodenal perforation were major complications. Invasive procedures of 8 abdominal thrombosis cases resulted with death due to ileus in one patient, and reocclusion in another. Seven of the 12 upper extremity/superior vena cava thrombosis cases resulted with reocclusions. CONCLUSIONS: Endovascular and surgical interventions seemed to be unsuccessful because of recurrent infectious and vascular complications in 22 (53.6%) of 41 patients with venous thrombosis. The indication of these procedures is controversial. Their economic burden on the healthcare system must be considered.

RESUMO

Several epidemiologic studies report on the prevalence of Behçet's syndrome (BS) and demographic and clinical findings in patients from different countries and ethnicities. Although these studies point out geographic differences in disease course, methodologic differences make it difficult to compare the results of these studies. Recent data suggest that neutrophil extracellular trap levels are elevated in patients with BS, and that it may be a potential therapeutic target for the reduction or prevention of BS-associated thrombotic risk. Details on the mode of functioning of ERAP have been delineated and further epigenetic data reported. Wall thickness of lower extremity veins is increased among BS patients without any apparent clinical involvement. Magnetic resonance (MR) venography and Doppler ultrasonography (USG) were comparable in the diagnosis of chronic deep vein thrombosis, while MR venography is more effective in detecting collateral formations. Results were also collected on some dietary and non-dietary factors in triggering oral ulcers, while smoking seems to have a protective role. With regards to the therapy, it has been demonstrated that endovascular interventions carry the risk of inducing pathergy phenomenon. Apremilast has been convincingly shown to be useful for oral ulcers of BS and classical immunosuppressives are effective as first line therapy in more than half of patients with uveitis. While infliximab and adalimumab seem to be equally effective in the treatment of refractory uveitis of BS, the combination of adalimumab and immunosuppressives appears to be superior to immunosuppressives alone for venous thrombosis of the extremities. In addition, tocilizumab might be an alternative to anti-TNF agents for patients with arterial involvement refractory to immunosuppressives. On the other hand, the place of IL-17 inhibition in the treatment of BS still remains questionable.

RESUMO

BACKGROUND: Acute thrombosis in the system of the inferior vena cava is one of the most common vascular diseases and is of serious danger as a potential source of one of the most severe complications. In order to assess efficacy of open thrombectomy for embologenic iliofemoral venous thromboses we carried out comparison of the results of open thrombectomy and implantation of cava filters in a total of 119 patients presenting with iliofemoral thrombosis. PATIENTS AND METHODS: Open thrombectomy was performed in a total of 59 patients. Of these, 12 patients with segmental thromboses underwent radical thrombectomy and 47 patients with disseminated forms of thrombosis were subjected to partial thrombectomy with plication of the femoral vein. In 5 patients, the operation was supplemented with applying an arteriovenous fistula. Efficacy of operations was assessed with the help of ultrasonographic duplex angioscanning and regression of clinical manifestations. In the remote period, the degree of manifestations of post-thrombotic disease was assessed by means of the Villalta scale. RESULTS: After radical thrombectomy, patency of the iliofemoral segment was preserved in all patients during the whole follow-up period. In the group of patients with partial thrombectomy, 5 (9.5%) patients developed rethrombosis above the placation site at terms from 8 to 12 months. Four-year patency of the iliofemoral segment in this group of patients amounted to 81.5%. In patients with implanted cava filters, neither femoral vein nor iliac segment were patent completely. During the first year, thrombosis of cava filter developed in 9 cases; after 2 years, occlusion of the cava filter was diagnosed in 7 patients. In clinical assessment of the remote results with the use of the Villalta scale in patients after open thrombectomy the symptoms of post-traumatic disease were absent or weakly pronounced. After implantation of the cava filter all patients demonstrated the clinical course of post-traumatic disease, corresponding to 10-15 points. CONCLUSION: Open thrombectomy for iliofemoral embologenic thromboses performed at specialized departments is a radical method of preventing thromboembolic complications and promotes restoration or improvement of venous blood flow in the extremity.

RESUMO

Objective: To assess the technical success rate, stent patency, clinical efficacy and complications of stent placement for filter-related chronic occlusion of the inferior vena cava. Methods: A retrospective analysis was carried out for 12 patients with filter-related chronic occlusion of the inferior vena cava associated with severe post-thrombotic syndrome, who underwent stent placement after ineffective conservative therapy at Nanjing First Hospital from March 2016 to December 2018,9 males and 3 females, aged from 48 to 77 years, mean age 60 years, six had bilateral lower extremity symptoms and six had unilateral lower extremity symptoms.Technical success rate, stent patency, clinical efficacy and complications of stent placement were recorded. Clinical success was defined as relief of symptoms and a decrease in clinical, etiology, anatomy, and pathophysiology (CEAP) score for at least grade 1. Results: Stent placement in the unilateral or bilateral iliocaval occlusion was successful in 11 patients. The cause of technical failure in the single patient with failed stent placement was an inability to cross the occluded left iliacvein and the patient was treated with stent placement in the right iliocaval vein.There were 7 patients with inferior vena cava and unilateral iliocaval stent placement; 5 patients with inferior vena cava and bilateral iliocaval stent placement. Acute stent thrombosis occlusion occurred in 1 case after the operation, the blood flow recanalized after catheter-directed thrombolysis and re-stenting. All patients were followed up for 6 to 24 months, with an average of (13±6) months. During the follow-up period, CTV or venography of lower limbs showed that the blood flow in the stent was unobstructed. At the last follow-up, 12 patients were evaluated as clinically effective. Three patients had transient treatment of lateral lumbar pain during operation, which alleviated by themselves.No significant abdominal pain, severe hemorrhage, symptomatic pulmonary embolism and other complications related to treatment occurred in all patients during perioperative period and follow-up. Conclusion: Stent placement is safe and feasible in the treatment of filter-related chronic occlusion of the inferior vena cava, which can alleviate the clinical symptoms of severe post-thrombotic syndrome.

RESUMO

A 65-year-old woman was diagnosed with simultaneous hepatic metastasis of rectal cancer with portal venous tumor thrombi(Vp3)that developed in the bifurcation of the portal vein. Four days from the first visit, abdominal dynamic contrastenhanced CT image on the portal venous phase shows that the tumor thrombi progressed in the main trunk of the portal vein (Vp4). We decided that it was a condition of oncologic emergency and initiated FOLFOXIRI plus BV therapy. After 12 courses, tumor shrinkage and regression of the portal venous tumor thrombi were achieved, but conversion surgery was impossible because the collateral circulation of the hepatic portal region remained. The treatment target was changed to the extension of the survival period. The initiation and reinitiation of FOLFOXIRI plus BV therapy and maintenance of 5-FU/l-LV plus BV therapy contributed to disease control in 24 months and survival period of 36months.

RESUMO

RATIONALE: Peripherally inserted central catheters (PICC), normally located at the lower 1/3rd of the superior vena cava (SVC) and cavo-atrial junction, are commonly used in cancer patients. Persistent left superior vena cava (PLSVC) is a vascular anomaly, in patients with which seldom research was reported about PICC implanted. After obtaining written informed consent, we present a case where two successful insertions of PICC were performed in a 50-year-old female patient with PLSVC and right SVC. PATIENTS CONCERNS: The patient had ovarian cancer and was admitted for chemotherapy using PICC. DIAGNOSES: Ovarian cancer and PLSVC. INTERVENTIONS AND OUTCOMES: Following insertion of PICC in PLSVC, thrombosis developed. PICC was removed after routine anticoagulation therapy. Owing to tumor recurrence, a second PICC was inserted in the right SVC without any complications. LESSONS: PICC insertion in PLSVC for chemotherapy may be associated with an increased risk of deep venous thrombosis of the upper extremity. A right catheter insertion in patient with PLSVC was preferred.

RESUMO

BACKGROUND: Total hip arthroplasty (THA) relieves pain and restores function in patients with severe rheumatoid arthritis and osteoarthritis. Over the past few decades, several authors have attempted to assess the efficacy and safety of simultaneous bilateral THA compared with staged bilateral THA. The purpose of this meta-analysis is to compare the mortalities and complications between simultaneous bilateral THA and staged bilateral THA. METHODS: A literature search to identify eligible studies was undertaken to identify all relevant articles published until August 2018. We included studies that compared simultaneous bilateral THA and staged bilateral THA and their effects on mortality and complications. The outcomes included mortality, the occurrence of deep venous thrombosis (DVT), the occurrence of pulmonary embolism (PE), respiratory complications, cardiovascular complications, digestive system complications and the occurrence of dislocation. Stata 12.0 was used for the meta-analysis. RESULTS: Nineteen studies involving 59,257 patients were identified; among them, 16,758 patients were selected for treatment with simultaneous bilateral THA, and 42,499 patients were chosen for the purpose of staged bilateral THA. The meta-analysis results demonstrated that there was no significant difference between simultaneous bilateral THA and staged bilateral THA in terms of mortality (risk ratio [RR] = 1.15, 95% CI = 0.76, 1.74; P = .520). Compared with staged bilateral THA, simultaneous bilateral THA was associated with a reduction in the occurrence of DVT, PE and respiratory complications (P < .05). There were no significant differences in the cardiovascular complications, digestive system complications or the occurrence of dislocation and infection (P = .057). CONCLUSIONS: We observed that the prevalence of DVT, PE and respiratory complications was considerably lower with the use of simultaneous bilateral THA than with the use of staged bilateral THA. Thus, simultaneous bilateral THA is a considerably safer procedure than staged bilateral THA in selected THA patients.

RESUMO

Venous thromboembolic events (VTE), defined by deep vein thrombosis or pulmonary embolism, are potentially serious complications after gynecologic surgery. Without thromboprophylaxis, they are common and can lead to significant morbidity and mortality. Conversely, poorly adapted prophylaxis can be hazardous. Risk factors related to the patients and to the types of surgery have been identified and can be used to adapt the prophylaxis. Several recommendations have been proposed; however, no clear consensus exists. This article reviews the pathophysiology and specific risk factors of post-gynecologic surgical VTE and provides comprehensive and practical recommendations for perioperative thromboprophylaxis in gynecology, based on various international recommendations.

RESUMO

BACKGROUND: Portal hypertension commonly accompanies advanced liver disease and often gives rise to life-threatening complications, including haemorrhage from oesophageal and gastrointestinal varices. Variceal haemorrhage commonly occurs in children with chronic liver disease or portal vein obstruction. Prevention is therefore important. Following numerous randomised clinical trials demonstrating efficacy of non-selective beta-blockers and endoscopic variceal ligation in decreasing the incidence of variceal haemorrhage, primary prophylaxis of variceal haemorrhage in adults has become the established standard of care. Hence, band ligation and beta-blockers have been proposed to be used as primary prophylaxis of oesophageal variceal bleeding in children. OBJECTIVES: To determine the benefits and harms of band ligation compared with any type of beta-blocker for primary prophylaxis of oesophageal variceal bleeding in children with chronic liver disease or portal vein thrombosis. SEARCH METHODS: We searched The Cochrane Hepato-Biliary Group Controlled Trials Register (February 2019), CENTRAL (December 2018), PubMed (December 2018), Embase Ovid (December 2018), LILACS (Bireme; January 2019), and Science Citation Index Expanded (Web of Science; December 2018). We scrutinised the reference lists of the retrieved publications and performed a manual search from the main paediatric gastroenterology and hepatology conferences (NASPGHAN and ESPGHAN) abstract books from 2009 to 2018. We searched ClinicalTrials.gov for ongoing clinical trials. There were no language or document type restrictions. SELECTION CRITERIA: We planned to include randomised clinical trials irrespective of blinding, language, or publication status for assessment of benefits and harms. We planned to also include quasi-randomised and other observational studies retrieved with the searches for randomised clinical trials for report of harm. DATA COLLECTION AND ANALYSIS: We planned to summarise data from randomised clinical trials using standard Cochrane methodologies. MAIN RESULTS: We found no randomised clinical trials assessing band ligation versus beta-blockers for primary prophylaxis of oesophageal variceal bleeding in children with chronic liver disease or portal vein thrombosis. AUTHORS' CONCLUSIONS: Randomised clinical trials assessing the benefits or harms of band ligation versus beta-blockers for primary prophylaxis of oesophageal variceal bleeding in children with chronic liver disease or portal vein thrombosis are lacking. There is a need for well-designed, adequately powered randomised clinical trials to assess the benefits and harms of band ligation versus beta-blockers for primary prophylaxis of oesophageal variceal bleeding in children with chronic liver disease or portal vein thrombosis. Those randomised clinical trials should include patient-relevant clinical outcomes such as mortality, failure to control bleeding, and adverse events.

RESUMO

BACKGROUND: To assess whether the ultrasound (US) is a reliable approach in detecting lower-limb deep-vein thrombosis (DVT) in patients without symptoms of DVT. METHODS: The research team performed a systematic search in PubMed, Ovid, Cochrane, and Web of Science without language or date restrictions. Full-text reports on prospective diagnostic studies involve the detection of lower-limb proximal and distal DVT in patients without symptoms of DVT using US and venography. A meta-analysis was performed using Meta-DiSc (version 1.4), providing the pooled sensitivity, specificity, positive (LR+) and negative (LR-) likelihood ratios of the detection accuracy of US. There were 4 different classes of subgroup analysis-the class of patients stratified by location of US exam (proximal, distal, whole leg), the class stratified by technique (color/doppler, compression, both modalities), the class stratified by kind of surgery (orthopedic, otherwise hospitalized) and the class stratified by era of publishing (1980s, 1990s, 2000s). The study quality and the risk of bias were evaluated using QUADAS-2, with heterogeneity was assessed and quantified by the Q score and I statistics, respectively. RESULTS: The meta-analysis included 26 articles containing 41 individual studies with a total of 3951 patients without symptoms of DVT. Using venography as the gold standard, US for proximal DVT had a pooled sensitivity of 59% (95% confidence interval (CI) = 51%-66%) and a pooled specificity of 98% (95% CI = 97%-98%), US for distal DVT had a poor sensitivity of 43% (95% CI = 38%-48%) and a pooled specificity of 95% (95% CI = 94%-96%), US for whole-leg DVT had a pooled sensitivity of 59% (95% CI = 54%-64%) and a pooled specificity of 95% (95% CI = 94%-96%), US for post-major orthopedic surgery patients had a pooled sensitivity of 52% (95% CI = 49%-55%), and US for other types of patients had a pooled sensitivity of 58% (95% CI = 43%-72%). Pure compression technique for DVT had a poor sensitivity of 43% (95% CI = 39%-48%), pure color/doppler technique for DVT had a pooled sensitivity of 58% (95% CI = 53%-63%), compression and color/doppler technique for DVT had a pooled sensitivity of 61% (95% CI = 48%-74%). CONCLUSION: US could be a useful tool for diagnosing DVT, but it has a lower positive rate and a higher false negative rate. The rate of missed diagnosis of lower-limb DVT by US amounts to 50% or so in the patients without symptoms of DVT. The negative results do not preclude the possibility of DVT and if appropriate heightened surveillance and continued monitoring or try a more accurate inspection method is warranted. The whole leg evaluation and color/doppler technique should be the preferred approach.

RESUMO

The aim of the study was to report the experience and outcomes of Xp11.2 translocation renal cell carcinoma (tRCC) patients with tumor thrombus undergoing radical nephrectomy and thrombectomy.Between January 2017 and December 2017, 66 consecutive patients with RCC and venous thrombus involvement received surgical treatment at Peking University Third Hospital. Of which, 5 patients were confirmed of Xp11.2 tRCC, 61 patients were diagnosed of non-tRCC subtypes including 45 ccRCCs, 10 pRCCs, and 6 other subtypes. Demographic, clinical, operation, pathological and follow-up data were extracted for analysis. Prognostic factors were identified by Cox regression analysis.All the patients received radical nephrectomy and thrombectomy successfully. During a median follow-up of 18 months, 5 patients in non-tRCC group and 1 patient in tRCC group died of disease progression. Survival analysis revealed that Xp11.2 tRCC patients experienced shorter DFS than non-tRCC patients, however, there is no significant difference in OS between two groups. Xp11.2 tRCC histological subtype and presence of metastasis at diagnosis were identified as independent negative factors of DFS by multivariate analysis.Radical nephrectomy with thrombectomy provides an acceptable efficacy for tRCC patients with tumor thrombus extending into the venous system. In addition, multimodality treatment should be considered for advanced Xp11.2 RCCs as this subtype was a negative prognostic factor of DFS.

RESUMO

BACKGROUND: Portal vein thrombosis (PVT) is a life-threatening complication after hepatectomy. However, the relationship between postoperative PVT and morphometric features of the PV has not been fully elucidated yet. PATIENTS AND METHODS: A total of 81 patients who underwent hepatectomy for perihilar cholangio-carcinoma (PHCC) were studied. We investigated the diameters and angles of PV using pre- and postoperative computed tomography (CT) reconstructed by SYNAPSE VINCENT®. RESULTS: The incidence of PVT after hepatectomy was 11.1%. There were significant differences with respect to the remnant liver PV diameter (p=0.015), the diameter ratio (p=0.001), and the postoperative PV angle (p=0.001) between patients with and without PVT. Multivariate analysis revealed that a postoperative PV angle of less than 90° (p=0.008) and a diameter ratio of less than 45% (p=0.041) were independent risk factors for PVT. CONCLUSION: A postoperative PV angle of less than 90° and diameter ratio of less than 45% eventually lead to PVT after hepatectomy for PHCC.

RESUMO

BACKGROUND: Post-thrombotic syndrome (PTS) is a long-term complication of deep vein thrombosis (DVT) characterised by chronic complaints such as oedema and skin changes including; venous ectasia, varicose veins, redness, eczema, hyperpigmentation, and in severe cases fibrosis of the subcutaneous adipose in the affected limb. These chronic complaints are the effects of venous outflow restriction that can cause symptoms such as heaviness, itching, pain, cramps, and paraesthesia. Twenty to fifty percent of people with DVT develop post-thrombotic complications. Several non-pharmaceutical measures are used for prevention of PTS during the acute phase of DVT. These include elevation of the legs and compression therapy. There have been limited studies regarding the effectiveness of compression therapy for prevention or treatment of PTS. As a result, clinicians and guidelines differ in their assessment of compression therapy during treatment of DVT and in the treatment of PTS. This is an update of a review first published in 2003. OBJECTIVES: To assess the effectiveness of compression therapy for treatment of post-thrombotic syndrome, including elastic compression stockings and mechanical devices compared with no intervention, placebo and with each other. SEARCH METHODS: For this update, the Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase and CINAHL databases and World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registries on 2 July 2018. SELECTION CRITERIA: We included trials that evaluated compression therapy for the treatment of PTS. The primary outcomes were severity of PTS and adverse effects. There were no restrictions on date or language. Two review authors (SA, DNK) independently assessed whether potentially relevant studies met the inclusion criteria. DATA COLLECTION AND ANALYSIS: One review author extracted and summarised data and one review author (DNK) verified them. We resolved disagreements by discussion. We assessed methodological study quality with the Cochrane 'Risk of bias' tool. We used GRADE to assess the overall certainty of the evidence supporting the outcomes assessed in this review. MAIN RESULTS: We identified four trials, with 116 participants, investigating the effectiveness of compression therapy for treatment of PTS. The methodology used by each trial was too heterogeneous to perform a meta-analysis, so we reported our findings narratively.Two trials studied the effect of graduated elastic compression stockings (GECS) on improvement of PTS symptoms. One study reported beneficial haemodynamic effects, while the other found no benefits on PTS severity compared to placebo (very low-certainty evidence). There was very limited evidence available for adverse effects and quality of life (QoL). The two studies did not report on compliance rates during the study period.Two trials studied the effects of intermittent mechanical compression devices. Both reported improvement in PTS severity (low-certainty evidence). Improvement of the severity of PTS was defined by treatment 'success' or 'failure'. Only one study comparing compression devices evaluated adverse effects and QoL. Although 9% of the participants experienced adverse effects such as leg swelling, irritation, superficial bleeding, and skin itching (moderate-certainty evidence), QoL was improved (moderate-certainty evidence). Studies did not assess compliance using intermittent mechanical compression devices.None of the studies evaluated patient satisfaction. AUTHORS' CONCLUSIONS: There is very low-certainty evidence regarding the use of GECS for treatment of PTS as assessed by two small studies of short duration. One study reported beneficial haemodynamic effects, while one found no benefits on PTS severity compared to control/placebo stockings. There is very limited evidence for adverse effects, patient satisfaction, QoL, and compliance rates. There is low-certainty evidence favouring use of intermittent pneumatic compression devices compared to a control device for the treatment of severity owing to different measurements used by the studies reporting on this outcome and small studies of short duration. There is moderate-certainty evidence of improved QoL but possible increased adverse effects related to compression device use owing to small studies of short duration. High-certainty evidence to support the use of compression therapy in prevention of PTS is lacking and any conclusions drawn from current evidence should be interpreted with care. Further research is needed to assess whether compression can result in long-term reduction and relief of the symptoms caused by PTS, or prevent deterioration and leg ulceration.

RESUMO

BACKGROUND: Both hyponatremia and portal vein thrombosis (PVT) reflect the severity of liver dysfunction and are independently associated with increased morbidity in cirrhotic patients. In this study, we analyzed effects of hyponatremia on PVT development. METHODS: Data on adult liver transplants (LTs) in the Model for End-Stage Liver Disease era through September 2016 were obtained. Receiver operating curves and multivariable logistic regression models were constructed to evaluate the association between serum sodium level and PVT. Based on the receiver operating curves, hyponatremia was defined as a sodium level below 125 mEq/L. RESULTS: Of the 49,155 recipients included, 16% had hyponatremia (n = 7828) and 9% had PVT (n = 4414) at transplant. Subjects with hyponatremia had lower rates of PVT at the time of LT (4.4% vs 10.1%, P < .001), incidence of nonalcoholic steatohepatitis (10.8% vs 16.5%, P < .001), diabetes (19.7% vs 24.3%, P < .001), and need for dialysis (8.8% vs 16.0%, P < .001) as well as higher rates of chronic hepatitis C and B (37.6% vs 29.1%, P < .001 and 2.9% vs 1.7%, P < .001). Multivariable regression analysis confirmed that hyponatremia was independently associated with a decreased likelihood of PVT (odds ratio [OR], 0.44, P < .001). African American patients had a lower incidence of PVT (OR, 0.70; P < .001). Variables associated with a higher incidence of PVT were: nonalcoholic steatohepatitis (OR, 1.15; P = .005), moderate-to-severe ascites (OR, 1.10; P = .008), and Hispanic ethnicity (OR, 1.2; P < .001). CONCLUSION: Hyponatremia is associated with a lower rate of PVT independent of severity of liver disease and other thrombotic risk factors. This protective effect should be taken into consideration during the perioperative management of hyponatremia in patients undergoing LT.
