Background: There is a paucity of reports on the deep vein thrombosis in our environment.Aims and Objective: The aim of this study is to document the role of Doppler ultrasound in detecting deep vein thrombosis in our environment.Methods and Materials: Between Januarys to December 2014 forty six in patients with suspicion of DVT were evaluated prospectively. All patients presented with symptoms of single or bilateral disease, and a high probability of the disease. Two trained radiologists performed all duplex scan examinations. The patients were scanned using Mindray DC-3/DC-3T Diagnostic ultrasound scanner (Mindray Bio- Medical Electronics Co., LTD) linear (7-12MHz) transducers was used.Results: A total of 46 patients had duplex-Doppler scan examination carried out between January-December 2014. There were 30(65.2%) males and 16(38.8%) females subjects recruited for the study. The mean age was 48.9±SD17.3 with range of 18-85 years. A total of 21 patients (45.6%) were found to have deep vein thrombosis (DVTs) on duplex-Doppler examination. Proximal DVTs was seen in 6(12.9%) and 14(30.3%) for right and left lower limbs respectively. Distal DVTs was seen in 1(2.2%) in the right lower limb and 25(54.4%) show normal findings bilaterally. Diffused DVTs was seen in 2(4.3%) patients involving external, through popliteal veins on the right lower limb. In 3(6.5%) of the patients only the common femoral, superficial femoral and popliteal shows diffuse DVTs.Conclusion: With availability of Doppler ultrasound in our environment the diagnosis of DVT is now easier. Duplex scanning techniques are faster, safer, and less expensive. Because of its noninvasive nature, venous duplex is repeatable, allowing for continued follow up after the diagnosis. Asian Journal of Medical Sciences Vol.7(6) 2016 53-57

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.

Background: Deep vein thrombosis (DVT) is a common but elusive illness that can result in disability and death if not recognized and treated effectively. The reported incidence has not changed much over past couple of decades. The aim of this study was to identify the risk of deep vein thrombosis related to the number of days of immobility and the role of low molecular weight heparin in the prevention of deep vein thrombosis.Methods: A total of hundred (n=100) patients undergoing laparotomy were studied in the post-operative period between January 2014 and December 2016. Patients were divided into two groups alternatively; Group I patients did not receive any DVT prophylaxis and Group II patients were given low molecular weight heparin once a day till mobilization. From 3rdPOD, all the patients were evaluated with detailed history and lower limb examination. D-dimer study was done in all the patients and if positive then followed by Color Venous Doppler. Regular follow-ups were done weekly once for a month, every two weeks for next month and once a month thereafter, minimum for 6 months.Results: A total of hundred (n=100) patients, including 65 men and 35 women, with median age of 40 years underwent laparotomies in 2 years by a single unit. The incidence of Lower Limb DVT in Group I was 8%. The risk factors associated with DVT were sex, BMI, smoking and Malignancy. The signs and symptoms associated with DVT were swelling of lower limbs, pain and tenderness, fever and Homan’s and Moses signs. The D-dimer test results were positive in 9 patients. Color Venous Doppler identified DVT in 8 patients. On regular follow- ups, remissions of clinical symptoms were recorded and repeat Doppler scans showed recanalization in all the patients after 6 months.Conclusions: Deep Vein Thrombosis is multifactorial, and post-operative patients account for majority of cases. Early mobilization and Prophylactic Low Molecular Heparin prevents DVT in abdominal surgeries.

This study assessed the performance of a pocket-sized ultrasound system for the diagnosis of proximal lower limb acute deep vein thrombosis (DVT) compared to a full-sized ultrasound system. Patients who needed urgent lower limb sonograms for acute DVT were invited for the study. In each examination, the investigator scanned the patient using the pocket-sized system and then repeated the scan using the full-sized system. The sensitivity, specificity, and accuracy of the pocket-sized system were determined in reference to the full-sized system. The venous segments that failed to be visualized using the two systems were compared. One hundred lower limbs comprising 500 venous segments were examined. There were four venous segments, including two mid and two lower femoral veins in two patients who failed to be visualized using both systems. The sensitivity, specificity, and accuracy for diagnosing proximal lower limb acute DVT were 100% (95% confidence interval [CI], 94.94%–100%), 100% (95% CI, 99.05%–100%), and 100% (95% CI, 99.19%–100%), respectively. The pocket-sized ultrasound system and the full sized-ultrasound system demonstrated a comparable performance in detecting acute DVT in the leg.

Introduction Catheter-directed thrombolysis (CDT) for iliofemoral deep vein thrombosis (DVT) restores venous patency, reduces the risk of the post-thrombotic syndrome and may reduce longer term treatment costs. This study assessed the potential role of CDT in patients with DVT with regard to representation following the index event. Methods A retrospective review of all patients with a positive lower limb DVT scan. Potential suitability of each patient to undergo CDT was based on well-recognized inclusion/exclusion criteria. Results In total, 1689 patients underwent a DVT-specific lower limb venous duplex. A total of 269 were found to have a DVT. Fifty-three of these patients met the inclusion criteria for CDT (only 2 underwent CDT). Fifty-nine of the 269 patients with an index DVT re-presented to our institution with a venous thromboembolism-related clinical event. These patients were significantly younger than those who did not reattend. A higher proportion of patients who represented were deemed suitable for CDT for the index DVT compared with those who did not represent (17/59 versus 36/210; P = 0.04). Conclusion This pragmatic study highlights the fact that significant number of patients return to secondary care with actual/perceived complications following initial diagnosis and treatment of a DVT which may have been amenable to CDT.
