RESUMO

Objective: To investigate the occurrence and risk factors of deep venous thrombosis (DVT) in adult burn patients. Methods: The clinical data of 1 219 adult burn patients admitted to the Department of Burns of Zhengzhou First People's Hospital from January 1, 2015 to August 31, 2016, conforming to the study criteria, were analyzed retrospectively by the method of case-control study, including 811 males and 408 females, aged 18-102 years. According to whether DVT occurred during hospitalization or not, the patients were divided into group DVT (n=12) and non-DVT group (n=1 207). The incidence of DVT, the diagnosis time of DVT, affected limbs, and DVT classification were counted and recorded. The gender, age, total burn area, D-dimer, lower limb burn, full-thickness burn, femoral vein indwelling central venous catheter (CVC) , inhalation injury, sepsis/infection shock, surgical operation, and infusion of concentrated red blood cells of patients between the two groups were compared with chi-square test, and then the indicators with statistically significant differences between the two groups were processed by multivariate binary logistic regression analysis to screen the independent risk factors of DVT in the adult burn patients. Results: (1) The incidence of DVT of adult burn patients was 0.98% (12/1 219), and DVT was diagnosed 24-138 days after injury, with a median of 61.5 days. DVT occurred in the right lower limb of 2 patients, left lower limb of 8 patients, and bilateral lower limbs of 2 patients, and DVT classification included 6 cases of mixed type and 6 cases of peripheral type. (2) There were no statistically significant differences in gender, age, and full-thickness burn of patients between the two groups ( χ(2)=1.524, 0.021, 3.115, P>0.05). There were statistically significant differences in total burn area, lower limb burn, inhalation injury, sepsis/infection shock, D-dimer, femoral vein indwelling CVC, surgical operation, and infusion of concentrated red blood cells among patients between the two groups (χ(2)=17.975, 6.206, 3.987, 8.875, 5.447, 15.124, 10.735, 14.031, P<0.05 or P<0.01). (3) Total burn area, D-dimer, and femoral vein indwelling CVC were independent risk factors for DVT in adult burn patients (odds ratio=10.927, 4.762, 9.394, 95% confidence interval=3.078-38.789, 1.197-18.934, 2.631-33.540, P<0.05 or P<0.01). Conclusions: The incidence of DVT in adult burn patients is relatively low, and the diagnosis time of DVT is 3 weeks after burn, with DVT classification of mixed type and peripheral type. The total burn area, femoral vein indwelling CVC, and D-dimer are independent risk factors for predicting DVT in adult burn patients.

RESUMO

BACKGROUND: Abdominal surgery may increase the risk of splanchnic vein thrombosis (SVT). We determined the incidence of SVT after abdominal surgery and identified groups at highest risk. MATERIALS AND METHODS: MEDLINE and Embase were searched for clinical studies evaluating the incidence of postoperative SVT after abdominopelvic surgery. Study selection, data abstraction, and risk of bias assessment were carried out independently by two reviewers. Clinical heterogeneity was explored by subgroup analyses (i.e., type of intra-abdominal procedure and organ group). RESULTS: Of 5549 abstracts screened, 48 were analyzed. Pooled incidence of SVT (n = 50,267) was 2.68% [95% confidence interval (CI), 2.24 to 3.11] (1347 events), I2 = 96%. Pooled incidence of SVT in high-risk procedures were splenectomy with devascularization (24%), hepatectomy in patients with cirrhosis (9%), and pancreatectomy with venous resection (5%). Pooled incidence of symptomatic and asymptomatic SVT was 1.02% (95% CI: 0.97% to 1.07%) and 0.98% (95% CI 0.88% to 1.07%), respectively. Most common causes of SVT-related mortality were irreversible thrombosis, bowel ischemia, liver failure, and gastrointestinal bleed. Most studies included were at a high risk of bias due to lack of prospective data collection and lack of SVT screening for all participants. CONCLUSIONS: Incidence of SVT after abdominal surgery is low but remains a relevant complication. Patients undergoing procedures involving surgical manipulation of the venous system and splenectomy are at the highest risk. Given the life-threatening risks associated with SVT, there is a need for larger prospective studies on the incidence and impact of SVT after abdominal surgery.

RESUMO

BACKGROUND: Pulmonary embolism and deep vein thrombosis are common clinical entities, and the related malpractice suits affect all medical subspecialties. Claims from malpractice litigation were analyzed to understand the demographics of these lawsuits and the common reasons for pursuing litigation. METHODS: Cases entered into the Westlaw database from March 5, 1987, to May 31, 2018, were reviewed. Search terms included "pulmonary embolism" and "deep vein thrombosis." RESULTS: A total of 277 cases were identified. The most frequently identified defendant was an internist (including family practitioner; 33%), followed by an emergency physician (18%), an orthopedic surgeon (16%), and an obstetrician/gynecologist (9%). The most common etiology for pulmonary embolism was prior surgery (41%). The most common allegation was "failure to diagnose and treat" in 62%. Other negligence included the failure to administer prophylactic anticoagulation while in the hospital (18%), failure to prescribe anticoagulation on discharge (8%), failure to administer anticoagulation after diagnosis (8%), and premature discontinuation of anticoagulation (2%). The most frequently claimed injury was death in 222 cases (80%). Verdicts were found for the defendant in 57% of cases and for the plaintiff in 27% and settled in 16%. CONCLUSIONS: The most frequently cited negligent act was the failure to give prophylactic anticoagulation, even after discharge. The trends noted in this study may potentially be addressed and therefore prevented by systems-based practice changes. The most common allegation, "failure to diagnose and treat," suggests that first-contact doctors such as emergency physicians and primary care practitioners must maintain a high index of suspicion for deep vein thrombosis/pulmonary embolism.

RESUMO

BACKGROUND: In clinical medicine, little is known about the use of allografts for portal vein (PV) reconstruction after pancreaticoduodenectomy (PD). Portal and caval systems are physiologically different, therefore the properties of allografts from caval and portal systems were studied here in a pig model. MATERIALS AND METHODS: PD with PV reconstruction with allogeneic venous graft from PV or inferior vena cava (IVC) was performed in 26 pigs. Biochemical analysis and ultrasonography measurements were performed during a 4-week monitoring period. Computer simulations were used to evaluate haemodynamics in reconstructed PV and explanted allografts were histologically examined. RESULTS: The native PV and IVC grafts varied in histological structure but were able to adapt morphologically after transplantation. Computer simulation suggested PV grafts to be more susceptible to thrombosis development. Thrombosis of reconstructed PV occurred in four out of five cases in PV group. CONCLUSION: This study supports the use of allografts from caval system for PV reconstruction in clinical medicine when needed.

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

Portal vein system thrombosis (PVST) is a form of venous thrombosis, which behaves as a common and potentially life-threatening complication after splenectomy. Numerous studies have been made to investigate the mechanism and the risk factors of PVST. However, the research on the prevention and treatment of PVST associated with platelet's (PLT) rule of change is rare. This work mainly investigates the PLT's rule of change and its correlativity with the formation of PVST after splenectomy. The retrospective study included 117 patients who underwent splenectomy from August 2014 to June 2018 and monitored by blood routine, D-dimer (D-D), and portal vein system ultrasound routinely after splenectomy. The changes of PLT and D-D were recorded and compared before and after each operation. We analyzed the changes of PLT and D-D as well as the incidence of PVST postoperatively. Most of the patients' PLT increased significantly after splenectomy. On the first day after operation, there were 80 patients' (68.38%) PLT recovered to normal or above normal. The proportion of patients with abnormally high PLT value on the seventh and fourteenth day were 60.68 per cent and 81.20 per cent, respectively. Thereinto, there were 67 patients' (57.26%) PLT beyond 500 × 109/L on the 14th day. The D-D of all patients exceeded the normal range on the first, seventh, and fourteenth day after operation, and the difference was statistically significant (P < 0.05), which behaved similar like PLT. Meanwhile, our color Doppler ultrasonography showed that the incidence of PVST was 70.79 per cent. Among the patients with PVST, 82 (100%) patients' PLT was increased after operation. The PLT of patients increased obviously after splenectomy. The increased blood viscosity caused by the consecutive elevation of PLT may result in a higher PVST incidence. Early intervention and treatment are needed clinically for PVST after splenectomy.

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

BACKGROUND: Burkholderia pseudomallei is a gram-negative bacterium and the causative pathogen of melioidosis, which manifests a variety ranges of infection symptoms. However, deep venous thrombosis (DVT) and pulmonary embolism (PE) secondary to bacteremic melioidosis are rarely documented in the literature. Herein, we reported a fatal case of melioidosis combined with DVT and PE. CASE PRESENTATION: A 54-year-old male construction worker and farmer with a history of diabetes was febrile, painful in left thigh, swelling in left lower limb, with chest tightness and shortness of breath for 4 days. He was later diagnosed as DVT of left lower extremity and PE. The culture of his blood, sputum and bone marrow samples grew B. pseudomallei. The subject was administrated with antibiotics (levofloxacin, cefoperazone/tazobactam, and imipenem) according to antimicrobial susceptibility testing and low molecular heparin for venous thrombosis. However, even after appropriate treatment, the patient deteriorated rapidly, and died 2 weeks after admission. CONCLUSIONS: This study enhanced awareness of the risk of B. pseudomallei bloodstream infection in those with diabetes. If a patient has predisposing factors of melioidosis, when DVT is suspected, active investigation and multiple therapeutic interventions should be implemented immediately to reduce mortality rate.

RESUMO

BACKGROUND: Primary thrombosis of the pulmonary vasculatures without extra-pulmonary sources of embolism are uncommon. Here, we report 2 cases of thrombosis of the stump of the remnant pulmonary vasculatures after lung resection complicated by embolic events with review of the literature. CASE PRESENTATION: A 75-year-old female was consulted to evaluate cardiac source of embolism for acute cerebral infarction. The patient underwent left upper lobectomy because of lung cancer 2 years ago. Cardiovascular imaging revealed about 1.6 cm × 1.4 cm sized thrombus within the remnant stump of the left superior pulmonary vein. The patient was treated by anticoagulation with warfarin, because the patients refused surgical removal of thrombus. A 57-year-old female who had a history of right pneumonectomy 10 years ago presented with dyspnea. Cardiovascular imaging revealed 1.7 × 1.5 cm sized thrombus in the right pulmonary artery stump and small pulmonary embolism in the left lower segmental pulmonary artery. The patient was treated by long-term anticoagulation with warfarin, and the thrombus and pulmonary embolism were resolved. CONCLUSION: The present cases demonstrated that very late thrombosis of the remnant pulmonary vascular structures and subsequent fatal embolic complications can develope even several years later after lung resection. Therefore, the dead space of the remnant vascular structures should be minimized during lung resection surgery, and the developement of delayed thromboembolic complications associated with vascular stump thrombosis should be carefully monitored.

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

Carbohydrate antigen 19-9 (CA 19-9) is a well-known tumor marker of adenocarcinoma (reference range, 37 U/mL). It can also be used, together with computed tomography, to monitor responses and resistance to chemotherapy in cancer patients. False elevation of CA 19-9 levels is often seen in conditions such as biliary tract obstruction and cholangitis. However, whether medication might induce false elevation of CA 19-9 levels has not yet been reported. A 74-year-old man was treated with third-line CPT-11 (irinotecan) plus panitumumab for stage IV cancer of the ascending colon. The patient developed chemotherapy-induced dysgeusia and was treated with polaprezinc. After polaprezinc administration, his CA 19-9 levels gradually increased from 18.9 to 1,699.4 U/mL. He developed deep vein thrombosis (DVT), although it was not associated with progressive disease or metastasis. Upon discontinuation of polaprezinc, CA 19-9 levels gradually decreased. This case demonstrates that polaprezinc may not only induce false elevation of CA 19-9 levels but also cause development of DVT induced by increased CA 19-9 levels, both of which are very rare events.

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

A 48-year-old woman was admitted to our hospital because of headache and fever. She was diagnosed with aseptic meningitis. Five days later, she had a seizure and developed left hemiparesis. Magnetic resonance imaging showed hyperintensity in the right parietal area on fluid attenuated inversion recovery imaging. She was diagnosed as having cerebral venous thrombosis (CVT) because the suprasagittal sinus was invisible on the venographic studies. Moreover, deep venous thrombosis (DVT) was detected in her left lower extremity. Laboratory findings showed hyperthyroidism and markedly increased factor VIII activity. This is a rare case of concomitant CVT and DVT induced by high factor VIII activity due to hyperthyroidism under the presence of meningitis, an additional risk factor for thrombosis.

RESUMO

PURPOSE: Advances in interventional radiology (IVR) treatment have notably improved the prognosis of hepatic vein (HV) and portal vein (PV) complications following pediatric living donor liver transplantation (LDLT); however, graft failure may develop in refractory cases. Although endovascular stent placement is considered for recurrent stenosis, its indications are controversial. METHODS: We enrolled 282 patients who underwent pediatric LDLT in our department from May 2001 to September 2016. RESULTS: 22 (7.8%) HV complications occurred after LDLT. Recurrence was observed in 45.5% of the patients after the initial treatment, and 2 patients (9.1%) underwent endovascular stent placement. The stents were inserted at 8 months and 3.8 years following LDLT, respectively. After stent placement, both patients developed thrombotic obstruction and are currently being considered for re-transplantation. 40 (14.2%) PV complications occurred after LDLT. Recurrence occurred in 27.5% of the patients after the initial treatment, and 4 patients (10.0%) underwent endovascular stent treatment. The stents of all the patients remained patent, with an average patency duration of 41 months. CONCLUSION: Endovascular stent placement is an effective treatment for intractable PV complications following pediatric LDLT. However, endovascular stent placement for HV complications should be carefully performed because of the risk of intrastent thrombotic occlusion and the possibility of immunological venous injury.

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.

RESUMO

BACKGROUND: Flap blood glucose decreases when flap congestion occurs. The hypothesis that flap blood glucose works as an indicator for venous congestion was tested experimentally, and flap congestion was reproduced in rodent models. METHODS: Blood glucose levels of a rat abdominal skin flap, with or without its vein pedicle clamped, were checked before and every 10 minutes after flap elevation. In rats whose pedicle vein was shut off, it was further followed up every 5 minutes after declamping. To examine the effect of systemic blood glucose on flap blood glucose, in some rats, glucose solution was administered intraperitoneally before the experiment to artificially produce hyperglycemia. Forty-two rats were divided into four groups, with (n = 24) or without (n = 18) venous blockage and with (n = 20) or without (n = 22) glucose preloading. RESULTS: Flap blood glucose decreased rapidly to off-scale low (<20 mg/dl) within 40 minutes only when the vein pedicle was shut off in normoglycemic (40 ± 8.2 minutes, mean ± SD) and hyperglycemic (40 ± 9.9 minutes) rat groups (p < 0.01). There was no significant difference in the time taken for the flap blood glucose to decrease to off-scale low after venous blockage between both groups (p = 0.379). When the vein was declamped, flap blood glucose again rapidly returned to the systemic level in 15 minutes or earlier in both groups (p = 0.0283). CONCLUSIONS: Flap blood glucose sensitively and specifically reflects the state of vein occlusion, whether the systemic blood glucose is normal or high. The authors' results indicate that flap blood glucose works as a reliable indicator for the venous system.
