Deep vein thrombosis (DVT) is a common vascular condition that affects 1 to 3 per 1,000 people annually. Proximal thrombosis (including iliac arteries) is at higher risk for postthrombotic syndrome (PTS). Therefore, in the present study, we investigated the effect of venoplasty by stent placement in patients with chronic venous symptoms following DVT in the iliofemoral segment.

In this cross-sectional study, patients with an age range of 20 to 70 years who presented with chronic symptoms of iliofemoral obstructive venous lesion following DVT were included in the study if satisfied. They were placed under local anesthesia with lidocaine and, if necessary, by venous sedation under lower extremity venography by catheter with popliteal vein surgery on the same side and placement of a sheet. Variables related to before the intervention and six months after the intervention were reviewed, recorded and analyzed.

Of the 24 patients participating in the study, 70.8% were male and 29.2% were female with a mean age of 51.42 8 8.27 years. There was a significant difference in pain and wound condition before and 6 months after the intervention (P <0.001). After the intervention, 58.3% of patients were in painless condition and the frequency of patients without wounds increased from 12.5% to 66.7%. Edema changes were not significant (P = 0.29)

Stent implantation in patients with chronic venous symptoms following DVT in the iliofemoral segment reduces pain and wound healing and is an effective, usable and practical method.

Nowadays, standard compression stockings are used to correct or balance thrombosis indicators in patients with deep vein thrombosis (DVT). The purpose of this study was to compare the effect of aerobic exercises combined with elastic pressure of the lower limbs on leukocytes, neutrophils, monocytes and lymphocytes in people with DVT.

30 middle-aged men (51 ± 4 Years) with DVT were randomly divided into three groups: 1) Aerobic training, 2) Aerobic exercise with elastic pressure, and 3) Control group. Aerobic training was performed for 8 weeks of running at an intensity range of 60-70% heart rate reserve. In the group of aerobic training + elastic pressure, elastic socks were used to create elastic pressure during training. Fasting levels of neutrophils, monocytes, lymphocytes and leukocytes were measured on 2 occasions: 24 before and 48 hours after the training period. Analysis of variance test was used to compare between-group changes and paired t-test was used to determine intra-group changes.

The results showed that aerobic + stretching training decreased leukocytes, lymphocytes, neutrophils and monocytes (p = 0.001), but the changes in the aerobic and control groups in none of Factors were not significant.

Using elastic compression stockings during regular aerobic exercises in people with DVT, through reducing and balancing pro-coagulation factors including leukocytes and its types including lymphocytes, monocytes and neutrophils leads to a decrease in the blood coagulation process among people with DVT.

Although deep vein thrombosis (DVT) is not a common disease in general population, it leads to life-threatening complications such as pulmonary embolism. It is more common in hospitalized patients and can be easily prevented by preventive methods, significantly.

Patients admitted to the Vascular Surgery Department l, who were hospitalized for more than three days, were evaluated for the incidence of deep vein thrombosis of the lower limbs by color Doppler ultrasound.  The frequency of DVT in patients was investigated according to age, gender, deep vein thrombosis prophylaxis and length of hospitalization.

Deep vein thrombosis was diagnosed in 59 out of 200 evaluated patients (29.5%), this frequency was regardless of age, sex, duration of hospitalization and DVT prophylaxis.60% patients have received DVT prophylaxis, and the frequency of DVT in this group was 13.3%. 40% patients did not receive DVT prophylaxis, and the frequency of DVT in this group was 53.8%.

It is recommended that adult patients hospitalized for vascular surgery receive DVT prophylaxis regardless of age, sex, and duration of hospitalization.  Considering that even the prescription of DVT prophylaxis cannot completely prevent DVT, it is recommended to use other preventive methods such as mechanical methods in vascular surgery patients with medium and high risk of DVT.

Venous thromboembolism (VTE) is the most important non-surgical complication in patients undergoing major urological surgery. Pulmonary embolism is the most common cause of death after urological surgery. Several clinical practice guidelines have been presented in different countries to prevent VTE, reduce the risk of VTE, and minimize the risk of bleeding. In Iran, there is no local clinical guideline for the prevention of VTE in urological surgery patients. Therefore, the present study aimed to review the clinical guidelines available in the world regarding thromboprophylaxis in urological surgery patients and present a summary.

The latest version of all available clinical guidelines related to VTE prophylaxis in urological surgeries until 2022 was searched using Medline (by PubMed), Google Scholar, Embase, and Trip database. After selection, each clinical guideline was reviewed by two researchers and a summary of their recommendations was presented.

During the database search, four clinical guidelines were included in this study. Among the present guidelines, only the European Urological Association guideline was appropriate for patients undergoing urological surgery, and the other three guidelines were related to hospitalized patients or those who underwent other surgeries, which in some parts addressed urological patients. According to the guidelines, the prevention methods of VTE prophylaxis are mechanical and pharmaceutical.

The present study showed that there is only one clinical guideline that has provided specific recommendations for urological surgeries, and other clinical guidelines have not specifically addressed these patients. A review of the aforementioned guidelines (whether specific to urology patients or not) showed a dearth of evidence and research on urological surgery patients, and decision-making is not easily possible in many cases. The results of the present study can be a step for the adaptation and approval of valid global guidelines and their use in our country. Moreover, due to the lack of clinical guidelines in Iran, the summary of the recommendations of this study can be used for clinical purposes.

Deep vein thrombosis (DVT) is one of the common cardiovascular diseases caused by the formation of clots in deep veins. The aim of this study was to determine the relative frequency of the risk factors of lower limb deep vein thrombosis in patients referred to teaching hospitals of Yasuj, Iran, from 2013 to 2014.

The present retrospective cross-sectional descriptive study was conducted in 2020. The participants of  study included 277 cases of DVT patients hospitalized in teaching hospitals of Yasuj, Iran. Furthermore, patients' characteristics such as age, sex, heart disease, kidney disease, smoking, congenital coagulation problems, history of DVT, use of oral contraceptives (OCP), history of cancer, limb fracture without surgery, diabetes, liver disease, blood pressure, use of catheter and length of stay in ICU were collected using a checklist. The collected data were analyzed using SPSS software and chi-square test.

The results of the present study indicated that 50.9% of DVT patients were women and 49.1% were men, and no statistically significant difference were observed between the two groups. The distribution of the frequency of people with DVT according to age group revealed that among the age groups of referring patients, the age range of above 50 years and the age range between 40 to 50 had the highest frequency, respectively. The frequency distribution of patients with DVT according to heart disease indicated that 13% of patients with DVT showed heart disease and 87% did not indicate heart disease. Out of a total of 277 patients studied, 7.9% had kidney problems and 92.1% had no sign of kidney problems. Furthermore, 40.8% of patients indicated high blood pressure and 59.2% did not show high blood pressure.

The results of the present study revealed that among the risk factors for the occurrence of DVT of the lower limbs, a history of heart disease, old age, kidney problems and blood pressure in the studied patients were indicators. On the other hand, other risk factors examined in the present study were trivial and and were not observed in the participants of the present study.

May-Turner syndrome is a relatively uncommon anatomical variation in which patients develop iliofemoral deep vein thrombosis (DVT) due to venous occlusion. In this syndrome, the left common iliac vein is compressed against the fifth lumbar vertebra by the right common iliac artery. The real incidence/prevalence of May-Turner syndrome is not precisely known, but it is estimated to be between 22 - 32% based on imaging studies. However, this syndrome is hardly ever considered in DVT diagnosis, especially in individuals with other risk factors. This venous occlusion may cause several symptoms such as leg swelling, venous thrombosis, or even more serious complications including pulmonary embolism.  The use of systemic anticoagulants alone is inefficient for the treatment of May-Turner syndrome, and more aggressive approaches are necessary to prevent clots recurrence. In this article, we described a case of a young woman suffering from pain and progressive swelling of the left lower limb without any provoking factors. With a comprehensive diagnostic approach including Doppler ultrasound and seeing a thrombus in the external iliac and left femoral veins and obstruction of the left common iliac vein in the venography images, it was determined that she has iliac vein compression syndrome. When facing unilateral venous thromboses, especially in younger age groups, the differential diagnosis should also consider May-Turner syndrome.

Deep Vein Thrombosis (DVT) is one of the most common problems in Intensive Care Units (ICU). The aim of this study was to investigate the relationship between clinical and demographic characteristics with lower extremity DVT in patients admitted to ICU.

The present study is a retrospective case-control study that was performed on 504 patients admitted to the ICUs of Al-Zahra Hospital in Isfahan during 2014-2019. Samples were easily included in the case group (89) and in the control group (415), randomly. Data were collected using a two-part questionnaire of demographic and clinical characteristics, then descriptive and analytical statistical tests such as two-sample independent t-test and if necessary Mann-Whitney were used and were eventually analyzed with SPSS version 21.

The results showed that the mean age of participants was about 53 years, although the mean age in the case group was higher than the control group (p=0.004), but after controlling sex and underlying diseases, had no effect on thrombosis (0.075). The chance of developing thrombosis in men was 1.7 times higher than women (p=0.029). The pao2 / fio2 index in patients with thrombosis (0.61±0.02) was significantly lower than the control group (5.5±2.1) (p<0.0001). After controlling for the effect of age and sex, the chance of thrombosis in patients with hypertension, diabetes, pulmonary embolism and previous history of thrombosis (p<0.0001), 2.6 (p<0.0001), respectively, 3.3 (p=0.006), 1/2 (p<0.0001) 8.1 (p<0.0001) was 36.3. Inactivity with a chance of 29.9 (p=0.0001) was the most important risk factor in ICU for thrombosis.

The results of this study show that having certain characteristics and having some underlying diseases due to which patients are admitted to special wards, increases the chance of developing DVT. Therefore, nurses can pay more attention to them in preventive planning and reducing their incidence.

Deep vein thrombosis and pulmonary embolism are fatal problems following brain trauma that, if left untreated, can dramatically increase mortality. Therefore, the present study aimed to evaluate deep vein thrombosis, pulmonary embolism and related factors in patients with traumatic brain injury.

This cross-sectional study was performed on 38 patients with isolated brain trauma in the intensive care unit. The study tool was a checklist that was completed as a file reading. The information required for the study was also collected through Doppler ultrasound and computed tomography angiography reports. The obtained data were analyzed in SPSS software using Chi-square and Fisher tests. The significance level of the tests was considered 0.05.

The mean age of study participants was 51.5± 18.3 years. In this study, 5.3% and 2.6% of participants had deep vein thrombosis and pulmonary embolism, respectively. There was a significant difference between the group with deep vein thrombosis and without deep vein thrombosis in the length of hospital stay, the mean length of stay in the ICU and the mean time of complete bed rest (CBR).

According to the effective variables in the development of thrombosis in this study, the development of related interventions to reduce the incidence of deep vein thrombosis and pulmonary embolism can minimize disability and mortality due to these diseases.

Due to the acceptance of laparoscopic hysterectomy by surgeons and patients and the fact that the prevalence of some complications of hysterectomy such as deep vein thrombosis, which is a dangerous and unpredictable complication, has not been accurately determined; this study was performed with aim to determine the factors affecting deep vein thrombosis following laparoscopic hysterectomy.

This descriptive cross-sectional study was performed in 2020 with participation of 55 women candidates for laparoscopic hysterectomy in Alzahra Hospital, Tabriz. The prevalence of deep vein thrombosis and its effective factors was evaluated with D-dimer test and the researcher-made checklist (extracted from articles). Data were analyzed by SPSS software (version 22) and Spearman coefficient test. P<0.05 was considered statistically significant.

The prevalence of deep vein thrombosis in the present study was 12.72%. Variables of age>60 years (P=0.001), high body mass index (P=0.009), previous history of deep vein thrombosis (P=0.008), history of long-term use of contraceptives (P=0.005) and prolonged immobility in the recent three months (P=0.011) were directly related to the incidence of deep vein thrombosis after abdominal hysterectomy.

The prevalence of deep vein thrombosis after laparoscopic hysterectomy in the present study was 12% that old age, high body mass index, use of contraceptives pills and complete immobility are its risk factors. It is recommended that preventive and therapeutic measures be considered before surgery for patients at risk for this complication.

Considering that anesthesia method is involved in the incidence of the symptoms of deep vein thrombosis (DVT) after abdominal hysterectomy, and this can be effective on the development of DVT, and lack of accurate information about the occurrence or non-occurrence of it leads to the start of treatment; this study was performed with aim to compare the incidence of the symptoms of DVT in general anesthesia and spinal anesthesia after abdominal hysterectomy.

This descriptive-analytical study was performed in 2019-2020 with participation of 70 women after abdominal hysterectomy that underwent the surgery under one of the two methods of general anesthesia and spinal anesthesia in Al-Zahra Hospital, Tabriz. DVT was diagnosed by the checklist of clinical symptoms and Doppler ultrasound. Data were analyzed by SPSS statistical software (version 22) and t-test and Chi-square test. P<0.05 was considered statistically significant.

The incidence of DVT symptoms in patients receiving general anesthesia was 17.14% and in those receiving spinal anesthesia was 22.85%; the incidence of these symptoms in the group receiving spinal anesthesia was non-significantly higher than the group receiving general anesthesia (P = 0.103). However, the incidence of this complication after Doppler ultrasound was zero in both groups.

The incidence of DVT was not significantly different in women candidates for abdominal hysterectomy that underwent surgery under one of the two methods of general anesthesia and spinal anesthesia; however, the method of anesthesia has no role in the incidence of DVT.

Deep vein thrombosis is a fatal complication during pregnancy. Lack of accurate knowledge of the epidemiology of this dangerous complication will lead to its concealment, followed by later diagnostic and ancillary measures; therefore, this study was performed with aim to epidemiological study of deep vein thrombosis in pregnant women admitted to the intensive care unit.

This descriptive-analytical study was performed in 2019 on 49 women admitted to the intensive care unit (before pregnancy and postpartum) in Taleghani and Al-Zahra hospitals (Tabriz Medical Sciences). Venous thrombosis information was recorded in the form related to the causes of deep vein thrombosis. Data were analyzed by SPSS statistical software (version 22) and Chi-square test. P<0.05 was considered statistically significant.

Smoking (P=0.036), obesity (P=0.011), diabetes (P=0.035), heart disease (P=0.033), hypertension (P=0.011), multiple (P=0.029), thrombocytopenia (P= 0.048), prenatal bleeding (P=0.041), blood transfusion during pregnancy (P=0.049), history of surgery in recent three months (P=0.048), amniotic infection (P=0.039) were the factors affecting deep vein thrombosis.

Smoking, obesity, diabetes, heart disease, hypertension, multiple births, thrombocytopenia, prenatal bleeding, blood transfusion during pregnancy, history of surgery in recent 3 months and amniotic infection are the risk factors for deep vein thrombosis in women admitted to the intensive care unit. Therefore, attention and care is essential in people with risk factors mentioned in pregnant women.
