Deep vein thrombosis (DVT) is a prevalent vascular disease characterized by pelvic and limb deep vein thrombophlebitis, and it has a high incidence in traumatic patients. Contrary to older studies, recent research has reported that recanalization in DVT is not a slow process. The present study aimed at the comparative examination of DVT recanalization with Doppler ultrasound in different intervals following treatment with heparin or enoxaparin. This prospective study was conducted on all traumatic patients hospitalized in Imam Reza Hospital of Kermanshah, Iran, with the clinical and sonographic diagnosis of DVT in limb veins. Doppler ultrasound was performed two weeks, one month, and three months following treatment in order to examine recanalization. Data were analyzed using statistical tests in SPSS16 at the significance level of <0.05. Based on Doppler ultrasound, a significant difference was found between the degree of recanalization in patients aged <45 years and those aged >45 years, between male and female patients, and between different DVT locations (P<0.05). After three months of treatment with heparin and enoxaparin, the degree of recanalization was increased in DVT. Moreover, it was found that Doppler ultrasound is a useful tool for the diagnosis of recanalization in patients with DVT.

SummaryPatients undergoing orthopedic surgery are at high risk of developing deep vein thrombosis. One hundred and thirty-eight consecutive patients undergoing total hip replacement or hip fracture surgery were included in this study. They were surveilled with colour Doppler ultrasound (CDU) and bilateral ascending contrast phlebography. The prevalence of proximal and distal DVT in this study was 5.8% and 20.3% respectively.CDU has a satisfactory sensitivity in patients with symptomatic deep vein thrombosis, especially in the proximal region. These results could not be confirmed in the present study of asymptomatic patients. The sensitivity was 62.5% (95% confidence interval: C.I. 24-91%) and the specificity 99.6% (C.I. 98-100%) for proximal DVT; 53.6% (C.I. 34-73%) and 98% (C.I. 96-99%) respectively for distal thrombi. The overall sensitivity was 58.1% (C.I. 39-75%) and the specificity 98% (C.I. 96-99%). The positive predictive value was 83.3% (C.I. 36-99%) and 75% (C.I. 51-91%) for proximal and distal DVT respectively. The negative predictive value was 98.9% (C.I. 98-100%) and 94.9% (C.I. 92-98%) for proximal and distal DVT respectively. The results of this study showed that even with a highly specialised and experienced investigator the sensitivity of CDU was too low to make it suitable for screening purposes in a high risk surgical population.

SummaryDoppler ultrasound flow examination, strain gauge plethysmography and contrast venography were performed in 160 lower limbs of 80 in-patients. Deep vein thrombosis (DVT) was suspected in 87 limbs. Using measurement of venous stop-flow pressure, the Doppler method had an overall sensitivity of 83%. By combined use of Doppler and Plethysmography, sensitivity was increased to 96%. Specificity was 62% and 51%, respectively. With a positive and a negative predictive value of 80% and 73%, respectively, the combination of both non-invasive methods cannot reliably replace venography in the diagnosis of DTV, although all (40/40) thromboses proximal to or involving the popliteal segment were detected by either Doppler and Plethysmography or both.After exclusion of 14 patients (18%) suffering from conditions known to alter the results of these non-invasive methods, the positive predictive value of abnormal findings in both Doppler and Plethysmography was increased to 94% for suspected limbs, whilst negative predictive value of both negative Doppler and Plethysmography was 90%, allowing the avoidance of venography in these patients.

Abstract Background Venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis (DVT), has significant morbidity and mortality. Acute PE, in particular, is fatal if we miss it, and symptomatic patients of PE sometimes have concomitant DVT. Purpose This study compared the risk of mortality in symptomatic patients of PE with and those without DVT in the long term. Methods The COMMAND VTE Registry is a multicenter registry enrolling consecutive 3027 patients with acute symptomatic VTE objectively confirmed by imaging examination or by autopsy among 29 centers in Japan between January 2010 and August 2014. Patients with both PE and DVT (N=1334) were regarded as PE patients, and the current study population consisted of 1715 PE patients and 1312 DVT patients. Results There were 1203 symptomatic patients of PE, including 381 without and 822 with DVT. In our cohort, the mean age was 67.9±14.9 years, 63% was female, 44% had hypertension, 12% diabetes mellitus, 5% history of VTE. There were 20% of active cancer. Baseline characteristics were well matched except for dyslipidemia (18% vs. 23%, p=0.021) and atrial fibrillation (8% vs. 5%, p=0.045). Patients without DVT had a more severe clinical presentation compared to those with DVT, including hypoxemia, shock and arrest. Moreover, Initial parenteral anticoagulation therapy in the acute phase was administered less frequently in patients without DVT (89% vs. 96%, P=0.0001). Two groups received thrombolysis (20% vs. 26%, P=0.18) and mechanical supports (Ventilator 14% vs. 5%, p<0.001, PCPS 5% vs. 3%, p<0.001, respectively). During follow-up, 93 (8%) patients experienced recurrent VTE events and 98 (8%) major bleeding events, and 323 (27%) patients died. The most frequent cause of death was cancer (11%). There were a significant differences in the cumulative incidences of all-cause death between the groups (32% vs. 24%, P=0.006), whereas there was significant difference in VTE-related death (13% vs. 4%, p<0.001). Estimated freedom rates from death for patients of PE without and those with DVT were as follows: 88% vs 99% at 10-day, 86% vs 95% at 1-month, 75% vs 83% at 1-year, and 64% vs 71% at 5-year, respectively. Landmark analysis Conclusions In symptomatic patients of PE, there was a difference in mortality between groups, but no difference in recurrent VTE. Patients without DVT had a more severe clinical presentation compared to those with DVT, and many VTE-related deaths in the acute phase. The one-month mortality rate differed statistically between groups, but there was no significant difference in long-term survival beyond one month. Most of deaths were due to underlying diseases, mainly cancer, and less commonly due to VTE in the long term.

Deep Vein

Fifty-three patients were examined because of suspected deep venous thrombosis, by means of clinical examination, Doppler ultrasound and venography. Eighty-two legs were examined with all three methods. Venography was positive in 40 and normal in 42. The clinical examination was false positive in 4 legs and false negative in 6. The Doppler ultrasound studies gave false positive results in 3 legs and false negative results in 6. These results are better than those reported in the literature probably because the thrombosis extended to the popliteal vein or the more proximal veins in 38 of the 40 legs with deep vein thrombosis. This high percentage of upper leg vein thrombosis can be explained by the fact that 47 of the 53 patients were ambulant when they developed the signs and symptoms of thrombosis. It is concluded, that the clinical examination and Doppler ultrasonography can be used to diagnose deep vein thrombosis in ambulant patients in our clinic. We presume that the findings reported in the literature cannot be used indiscriminately as a basis for diagnostic strategies in other hospitals because of widely varying categories of patients, referral patterns and diagnostic criteria that are virtually impossible to standardize.

Low Shear

An elevated blood viscosity could lead to increased venous stasis and a higher incidence of post-operative deep vein thrombosis. Immediately preoperatively we have measured, using a Contraves low shear 2 viscometer, blood yield stress and viscosity at high and low shear rate in 28 general surgical patients. These patients were then screened by the standard I125 fibrinogen technique to detect the development of deep vein thrombosis post-operatively.13 patients developed a deep vein thrombosis. These patients had a significantly higher blood yield stress, corrected to a standard haemoerit of 45%, than the others (P < 0.01 students t). All other viscosity parameters were normal in these patients. Patients with malignant disease had a very high incidence of thrombosis (90%: 30%) and significantly higher yield stress values (mean 0.26 dynes/cm2: mean 0.194 dynes/cm2, P < 0.0005 students t) compared to patients with benign disease.We conclude that a high blood yield stress could be an important aetiological factor in thrombosis and the high values obtained in patients with malignant disease could partly explain the high incidence in these patients.
