Rectus sheath hematoma (RSH) is an uncommon condition caused by hemorrhage into the rectus sheath. RSH is characterized by abdominal pain and an abdominal mass. This condition is associated with old age, childbirth, abdominal surgery, severe coughing, severe sneezing, anticoagulation therapy, and/or coagulation disorders. We report herein a case of RSH and pelvic cavity hematoma that was induced by dalteparin injection in a 77-year-old woman with pulmonary embolism and deep vein thrombosis, and who was successfully treated by conservative management.

Although heparin has over the years proven to be a reliable anticoagulant, there are still several undesirable side effects including dyslipidemia. Several recent publications have suggested that a low-molecular-weight heparin(LMWH) is superior to conventional heparin because it causes less side effects and has beneficial effects on lipid parameters. But the results of the study about lipid parameters are controversial. We conducted a prospective study to evaluate the efficacy, safetey and effect of LMWH on lipid parameters as an anticoagulant in hemodialysis therapy. 2500 a x a IU of LMWH(Fragmin ) were given to 51 maintenance hemodialysis patients (age:49.9+/-16.1, M:F=33:18) just before each dialysis for consecutive 12 hemodialysis. And 16 patients out of 51 patients were given for 6 months to compare the changes of lipid parameters with those in 22 patients with conventional heparin. The mean venous compression time and the degree of clot deposition in dialyzer were similar in both LMWH and conventional heparin group. The heparin concentration via anti-factor Xa-specific clotting method (Heptest ) in both groups was similar(0.64+/-0.24 vs 0.54+/-0.18IU/ml at 15 min, 0.32+/-0.13 vs. 0.26+/-0.24 IU/ml at 4 hours after starting hemodialysis). The hematologic parameters such as hemoglobin and platelet count level did not show any differences between the two types of heparin. The level of triglyceride was significantly decreased after 6 month by the LMWH therapy(177.6+/-60.9 vs 145.9+/-85.5mg/dl, P<0.05) but was not changed by the conventional heparin therapy(150.6+/-54.6 vs. 176.6+/-64.6, P=0.16). The level of HDL were significantly changed in both group(32.1+/-11.6 vs. 37.9+/-9.7mg/dl, P<0.05 in LMWH group , 40.4+/-11.9 vs. 33.7+/-7.8mg/dl, P<0.05 in conventional heparin group). The levels of total cholesterol and LDL-cholesterol were decreased in LMWH group but statistically insignificant. We conclude that LMWH is a suitable alternative to unfractionated conventional heparin for anticoagulation therapy and has beneficial effects on the lipoprotein profile in hemodialysis patients.

PURPOSE: To evaluate the effects and problems of venous thromboembolism (VTE) prophylaxis with a reduced dosage and administration period in Korean total knee arthroplasty (TKA) patients. MATERIALS AND METHODS: We analyzed 135 consecutive TKA patients with three different VTE prophylaxis regimens. Group dalteparin-aspirin (DA) injected dalteparin for the first 2 days, followed by taking aspirin for the next 5 days, Group aspirin (A) was on aspirin and Group dalteparin (D) on dalteparin 7 days postoperatively. We evaluated the incidence of VTE and safety among the 3 groups. RESULTS: Symptomatic deep vein thrombosis was detected in 4 cases (Group DA: 2, Group A: 1, Group D: 1). Pulmonary embolism (PE) was found in 1 case in each group with no fatal PE. Although no major bleeding complications were seen, minor bleeding incidents were detected in 14 cases (Group DA: 2, Group A: 1, Group D: 11), which was significant in Group D. No significant differences were observed in perioperative blood loss, effusion in the knee joint, thigh swelling or oozing on the wound area among the groups except thigh bruising, which developed more frequently in group D. CONCLUSION: The reduced dosage and administration period of VTE prophylactic medicine combined with mechanical prophylaxis for Korean TKA patients showed no fatal PE, but some minor bleeding incidents frequently developed with 7 days of dalteparin injections. We need to adjust the dosage and duration of prophylactic medication deliberately for Korean TKA patients, considering prophylaxis effectiveness and bleeding complication risks.

dalteparin.METHODS: The 162 eligible patients with gynecologic cancers who were treated with either dalteparin (n=60) or rivaroxaban (n=102) were reviewed. The primary outcome was a composite event, which included recurrence or clinically relevant bleeding events during the therapeutic period. Secondary outcomes were recurrence, clinically relevant bleeding events, and mortality.RESULTS: During the therapeutic period, there were no significant differences between the groups in the proportion of composite events, recurrence, or clinically relevant bleeding. Multivariate analysis using the Cox proportional hazards model also showed no significant difference in the number of composite events and clinically relevant bleeding between the groups. In the rivaroxaban group, 44.0% of patients experienced gastrointestinal bleeding and 24.0% experienced urinary tract bleeding. In the dalteparin group, bleeding was most common in the urinary tract (44.4%) and at the injection site (22.2%).CONCLUSION: In this study, although there were no significant differences in effectiveness or safety between the rivaroxaban and dalteparin groups, rivaroxaban use was associated with a higher rate of clinically relevant bleeding than dalteparin. Therefore, caution should be taken when prescribing rivaroxaban for gynecologic cancer-associated VTE and bleeding events should be carefully monitored.]]>

BACKGROUND: Venous thromboembolism (VTE) is a common and life-threating condition in cancer patients. Low molecular weight heparins (LMWH), such as dalteparin, are recommended in the treatment of VTE. Also, rivaroxaban, an orally administered direct factor Xa inhibitor, was approved for the treatment of VTE. It showed similar efficacy to standard therapy (LMWH or warfarin) and was associated with significantly lower rates of major bleedings. However, in the real world, bleeding has been reported to occur frequently in cancer patient receiving rivaroxaban. The goal of this research was to analyze bleeding risks between rivaroxaban and dalteparin for treatment of VTE in cancer patients. METHODS: Medical records of oncology patients who were treated with rivaroxaban or dalteparin for VTE from July 2012 to June 2014 were retrospectively reviewed. Data collected were as follows: age, sex, weight, height, cancer types and stages, ECOG (eastern cooperative oncology group) PS (performance score), VTE types, concurrently used medications, study drug information (dose and duration of therapy), INR (international normalized ratio), PT (prothrombin time), and platelet counts. Bleeding was classified into major bleedings, clinically relevant non-major bleedings, and minor bleedings. RESULTS: A total of 399 patients were included in the study. Of these patients, 246 were treated with rivaroxaban and 153 with dalteparin. Bleeding rates were significantly higher in the rivaroxaban group than in the dalteparin group (adjusted odds ratio (AOR) 2.09, 95% CI 1.22-3.60) after adjusting for confounders. In addition, rivaroxaban remained independently associated with 1.78-fold (95% CI 1.14-2.76) shorter time to bleeding compared to dalteparin after adjusting other factors known to be associated with poor outcomes. CONCLUSION: This study suggested that rivaroxaban was associated with an increased risk of bleedings in cancer patients.

BACKGROUND AND OBJECTIVES: The therapeutic efficacy of combined platelet glycoprotein IIb/IIIa receptor blocker with low molecular weight heparin (LMWH) is unknown for patients with acute myocardial infarction (AMI) and who underwent percutaneous coronary intervention (PCI). SUBJECTS AND METHODS: A total of 140 patients with AMI and who underwent high-risk PCI was divided into two groups: UFH (group I: 70 patients, 58.7+/-10.5 years of age), and dalteparin (group II: 70 patients, 59.6+/-9.8 years of age). The major adverse cardiac events (MACE) during hospitalization and during the 4 years after PCI were evaluated. RESULTS: The baseline clinical characteristics and angiographic characteristics were not different between the two groups. There were 62.9% totally occluded lesions with thrombus in both groups. Procedural success was achieved for 91.4% of the group I patients and for 90.0% of the group II patients. Any bleeding and hemorrhagic events were not different between the two groups. No significant intracranial bleeding was observed in both groups. The number of in-hospital MACEs was 7 (10.0%) in group I and 4 (5.7%) in group II. Four-year clinical follow-up was performed for 97% of the patients. As a result of the MACEs during the 4 years after PCI, death occurred in 6 (8.6%) patients in group I and in 7 (10.0%) patients in group II. Myocardial infarction occurred in 4 (5.7%) and 4 (5.7%) patients, respectively, target vessel revascularizations were done in 23 (32.9%) and 16 (22.9%) patients, respectively, and coronary artery bypass surgery was done in 3 (4.3%) and 1 (1.4%) patients, respectively. Overall, MACEs occurred in 33 (47.1%) patients of group I and in 26 (35.1%) patients of group II during the 4-year clinical follow-up (p=0.23). CONCLUSION: The long-term clinical outcome of dalteparin combined with abciximab is comparable with that of UFH plus abciximab for the high risk patients with AMI who receive PCI.

BACKGROUNDPrimary percutaneous coronary intervention (PCI) is the best treatment of choice for acute ST segment elevation myocardial infarction (STEMI). This study aimed to determine the clinical outcomes of tirofiban combined with the low molecular weight heparin (LMWH), dalteparin, in primary PCI patients with acute STEMI.

METHODSFrom February 2006 to July 2006, a total of 120 patients with STEMI treated with primary PCI were randomised to 2 groups: unfractionated heparin (UFH) with tirofiban (group I: 60 patients, (61.2 ± 9.5) years), and dalteparin with tirofiban (group II: 60 patients, (60.5 ± 10.1) years). Major adverse cardiac events (MACE) during hospitalization and at 4 years after PCI were examined. Bleeding complications during hospitalization were also examined.

RESULTSThere were no significant differences in sex, mean age, risk factors, past history, inflammatory marker, or echocardiography between the 2 groups. In terms of the target vessel and vascular complexity, there were no significant differences between the 2 groups. During the first 7 days, emergent revascularization occurred only in 1 patient (1.7%) in group I. Acute myocardial infarction (AMI) occurred in 1 (1.7%) patient in group I and in 1 (1.7%) in group II. Three (5.0%) patients in group I and 1 (1.7%) in group II died. Total in-hospital MACE during the first 7 days was 4 (6.7%) in group I and 2 (3.3%) in group II. Bleeding complications were observed in 10 patients (16.7%) in group I and in 4 patients (6.7%) in group II, however, the difference was not statistically significant. No significant intracranial bleeding was observed in either group. Four years after PCI, death occurred in 5 (8.3%) patients in group I and in 4 (6.7%) in group II. MACE occurred in 12 (20.0%) patients in group I and in 10 (16.7%) patients in group II.

CONCLUSIONSDalteparin was effective and safe in primary PCI of STEMI patients and combined dalteparin with tirofiban was effective and safe without significant bleeding complications compared with UFH. Although there was no statistically significant difference, LMWH decreased the bleeding complications compared with UFH.

BACKGROUNDPancreatic cancer is one of the most aggressive human malignancies. Lymphangiogenesis plays an important role in lymph node metastasis of many solid tumors. It is well known that low molecular weight heparins (LMWHs) can inhibit cell growth, cell invasion and angiogenesis, which are key processes in tumor progression.

METHODSWe measured the expression of vascular endothelial growth factor C (VEGF-C) in pancreatic cancer cells (PANC-1) using reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting. We used an in vitro assay to evaluate the anti-lymphangiogenic effect of an LMWH, Fragmin, on human lymphatic endothelial cell (HLEC) proliferation.

RESULTSFragmin at a low concentration can effectively inhibits HLEC proliferation induced by VEGF-C. VEGF-C secreted by PANC-1 cells stimulated HLEC proliferation. Low concentration LMWH suppressed HLEC proliferation induced by VEGF-C but did not affect proliferation or VEGF-C expression of PANC-1 cells, whereas high concentrations of LMWH inhibited PANC-1 cell proliferation.

CONCLUSIONSThese results suggest that VEGF-C released by cancer cells plays an important role in promoting HLEC proliferation. The LMWH Fragmin has anti-lymphangiogenic effects and may inhibit lymphatic metastasis in pancreatic cancer.
