Abstract. Treatment results of primary varicose disorders has been shown. The experience of using of thermal (endovenous laser ablation) and non-thermal methods (endovenous mechanochemical ablation, echo-controlled introduction of bioglue) in treatment of stage C2 chronic venous is shown. The purpose of this work is to evaluate the efficiency of endovenous ablation techniques. The treatment of 58 patients was analyzed. In the group of patients who underwent endovenous laser obliteration, reflux was not detected. In the group of patients with mechanochemical obliteration, reflux was determined in 3 patients (27.2%) at follow-up after 3 months required supplementation with foam sclerobliteration. In the group of patients with the introduction of bio glue, reflux was determined in 1 patient (20%) at the examination after 3 months. The received results lead to conclusion, that endovenous laser coagulation of affected veins is a reliable method of threatment, the gold standard. The advantage of non-thermal methods is the absence of thermal effects on the paravenous structures, respectively, patients have no pain during the procedure, increases comfort, and there is no risk of damage to the paravenous nerves. Another advantage of non-thermal techniques is no need to use of tumescent anesthesia, since only one puncture is required for the operation, which is comfortable for patients. The use of adhesive vein obliteration is justified in patients with signs of a short reflux duration and has an advantage for the patient due to the absence of the need for compression in the postoperative period. Non-thermal methods require further research and widespread implementation in practice.

Congenital anomalies of the caval vein are often associated with other abnormities such as heart defects, situs inversus or a polysplenia-asplenia-syndrome. An isolated, congenital malformation like aplasia of the inferior vena cava is a rare finding. A review of the embryology and abnormities, diagnostics, clinical signs and treatment is given together with the histories of two patients having thrombosis of the lower extremities and pelvic veins, caused by aplasia of the inferior vena cava. After thrombotic complications caused by vena cava aplasia there is high risk of recurrence. Those patients should be anticoagulated for lifetime.

SummaryIn patients with myeloproliferative disorders (MPD) a group of related diseases of the bone marrow stem cell and recurrent haemorrhagic and/or thrombotic complications, the production of aggregating prostaglandins (PGs) may be normal or slightly reduced, while PGI2 production is normal. However, MPD platelet sensitivity to antiaggregatory PGs is still unknown.We studied the potency of PGD2, PGI2 and PGEi as inhibitors of platelet aggregation induced by threshold aggregating concentrations of arachidonic acid and U-46619-analogue of the cyclic endoperoxide PGH2 in 20 patients with MPD in comparison with healthy controls, with the aim of evaluating the sensitivity of MPD platelets to antiaggregatory PGs. In these patients platelet prostanoid metabolism was normal. However, the functional response of platelets to aggregating and antiaggregating prostanoids was shifted towards potentially increased platelet aggregation response. These findings could have a clinical relevance in view of the haemostatic and thrombotic complications so frequent in MPD.

SummarySerial quantitative immunoelectrophoretic (IE) measurements of antithrombin III heparin cofactor (AT III) were made in groups of well and sick newborn infants classified by gestational age. Collection methods (venous vs. capillary) did not influence the results; serum IE measurements were comparable to AT III activity by a clotting method. AT III is gestational age-dependent, increasing from 28.7% of normal adult values at 28-32 weeks to 50.9% at 37-40 weeks, and shows a gradual increase to term infant levels (57.4%) by 3-4 weeks of age. Infants with the respiratory distress syndrome (RDS) show lower levels of AT III in the 33-36 week group, 22% vs. 44% and in the 37-40 week group, 33.6% vs. 50.9%, than prematures without RDS. Infants of 28-32 week gestational age had only slight differences, RDS = 24%, non-RDS = 28.7%. The lowest levels of AT III were seen in patients with RDS complicated by disseminated intravascular coagulation and those with necrotizing enterocolitis. Crossed IE on representative infants displayed a consistent pattern which was identical to adult controls except for appropriate decreases in the amplitude of the peaks. The thrombotic complications seen in the sick preterm infant may be related to the low levels of AT III.

SummaryTwenty-one cardiothoracic surgical patients have been treated with fibrin as a topical hemostatic/sealing agent, prepared from bovine fibrinogen clotted with bovine thrombin. Serum samples have been collected before treatment with fibrin and postoperatively between 1 and 9 days, 3 and 12 weeks, and 6 and 8 months. The titers of anti-bovine fibrinogen antibodies, measured by ELISA specific for immunoglobulins IgG or IgM, increased to maximal values after about 8 or 6 weeks, respectively. After 8 months, IgG titers were on average 20-fold lower than the mean maximal value, while IgM titers returned to the normal range. IgG was the predominant anti-bovine fibrinogen immunoglobulin as documented by ELISA, affinity chromatography and electrophoresis. Anti-bovine fibrinogen antibodies present in patients reacted readily with bovine fibrinogen, but did not cross-react with human fibrinogen as measured by ELISA or by immunoelectrophoresis. A significant amount of antibodies against bovine thrombin and factor V has been found, many cross-reacting with the human counterparts. No hemorrhagic or thrombotic complications, or clinically significant allergic reactions, occurred in any patient, in spite of antibody presence against some bovine and human coagulation factors. The treatment of patients with bovine fibrin, without induction of immunologic response against human fibrinogen, appeared to be an effective topical hemostatic/sealing measure.

Vascular Occlusions

SummaryHematopoietic colony-stimulating factors (CSFs) are largely used in patients with cancer undergoing cytotoxic treatment to accelerate neutrophil recovery and decrease the incidence of febrile neutropenia. Clinical practice guidelines for their use have been recently established (1), taking into account clinical benefit, but also cost and toxicity. Vascular occlusions have been recently reported among the severe reactions associated with the use of CSFs, in anedoctal case reports (2, 3), consecutive case series (4) and randomized clinical trial (5, 6). However, the role of CSFs in the pathogenesis of thrombotic complications is difficult to ascertain, because pertinent data are scanty and widely distributed over a number of heterogenous investigations. We report here a systematic review of relevant articles, with the aims to estimate the prevalence of thrombosis associated with the use of CSFs and to assess if this rate is significantly higher than that observed in cancer patients not receiving CSFs.

SummaryHuman platelets labeled with 51Cr were used to determine the contribution made by platelet lysis to the platelet release reaction and platelet aggregation induced by rabbit antihuman platelet serum (APS) and equine antihuman thymocyte globulin (ATG). Platelets were tested in both plasma (PRP) and non-plasma containing media. Antibodies directed against platelets, either as APS or ATG, induced significant amounts of platelet release and aggregation, as well as some degree of lysis, in the absence of complement. The presence of complement increased platelet lysis and aggregation, but not the release reaction. Non-immune horse gamma globulin produced different responses depending upon whether platelets were investigated in PRP or non-plasma containing media. Aggregation was seen in the latter but not the former. These differences can be explained by the presence of plasma components which prevent non-specific immune complexes from causing platelet aggregation. Since platelets in vivo are always in a plasma medium, one must be wary of utilizing data from platelet studies in synthetic plasma-free media as the basis of explaining clinical events. These observations demonstrate at least two, and possibly three, different mechanisms whereby ATG could activate platelets causing thrombotic complications and thrombocytopenia, i.e., via 1) specific and, 2) non-specific non-lytic pathways and 3) a lytic pathway.

The objective: To evaluate the clinical efficacy and safety of Enoxaparin-Pharmex for the prevention of thrombotic complications (pulmonary embolism) in the postoperative period in patients with moderate risk of these complications. Patients and methods. The study included 50 women after a caesarean section had an average degree of risk of pulmonary embolism. Patients were divided into the main group (n=25) and control group (n=25) in accordance with the treatment: patients of the main group received postoperative Еnoxaparin- Pharmex, group comparisons enoxaparin sodium (brand foreign manufacturer’s). Patients in both groups received the drug at a dose of 20 mg for 5 days, 1 time per day subcutaneously. Results. The research data analysis showed identity results of hemostasiogram of patients in the main group and the comparison group, no side effects after treatment in both groups. Conclusion. The clinical studies suggest the drug Enoxaparin-Pharmex is effective, safe LMWH, which can be used to prevent troboembolic complications, including post-operative treatment in obstetric practice. Spectrum of Enoxaparin-Pharmex can be extended to the prevention and treatment of thromboembolic conditions of varying severity with appropriate doses of the drug. Key words: Enoxaparin-Pharmex, prevention of pulmonary embolism.
