Lower Extremity Deep Venous Thrombosis
SECTION 5 Vascular System CHAPTER 34 Lower Extremity Deep Venous Thrombosis Ariel L. Shiloh KEY POINTS • Providers can accurately detect lower extremity deep venous thrombosis with point-of- care ultrasound after limited training. • Compression ultrasound exams are as accurate as traditional duplex and triplex vascular ultrasound exams. • Compression ultrasound exam at only two sites, the common femoral vein and popliteal vein, permits rapid and accurate assessment of deep venous thrombosis. Background care providers can perform lower extremity compression ultrasonography exams rapidly Venous thromboembolic disease (VTE) is a and with high diagnostic accuracy to detect common cause of morbidity and mortality in DVT. 7–13 A meta-analysis of 16 studies showed hospitalized patients and is especially preva- that point-of-care ultrasound can accurately lent in critically ill patients.1–3 Approximately diagnose lower extremity DVTs with a pooled 70% to 90% of patients with an identified source sensitivity of 96% and specificity of 97%.14 of pulmonary embolism (PE) have a proxi- Traditional vascular studies, the duplex mal lower extremity deep venous thrombosis and triplex exams, use a combination of (DVT).

Isolated Deep Venous Thrombosis: Implications for 2-Point Compression Ultrasonography of the Lower Extremity
IMAGING/ORIGINAL RESEARCH Isolated Deep Venous Thrombosis: Implications for 2-Point Compression Ultrasonography of the Lower Extremity Srikar Adhikari, MD, MS*; Wes Zeger, DO; Christopher Thom, MD; J. Matthew Fields, MD *Corresponding Author. E-mail: [email protected]. Study objective: Two-point compression ultrasonography focuses on the evaluation of common femoral and popliteal veins for complete compressibility. The presence of isolated thrombi in proximal veins other than the common femoral and popliteal veins should prompt modification of 2-point compression technique. The objective of this study is to determine the prevalence and distribution of deep venous thrombi isolated to lower-extremity veins other than the common femoral and popliteal veins in emergency department (ED) patients with clinically suspected deep venous thrombosis. Methods: This was a retrospective study of all adult ED patients who received a lower-extremity venous duplex ultrasonographic examination for evaluation of deep venous thrombosis during a 6-year period. The ultrasonographic protocol included B-mode, color-flow, and spectral Doppler scanning of the common femoral, femoral, deep femoral, popliteal, and calf veins. Results: Deep venous thrombosis was detected in 362 of 2,451 patients (14.7%; 95% confidence interval [CI] 13.3% to 16.1%). Thrombus confined to the common femoral vein alone was found in 5 of 362 cases (1.4%; 95% CI 0.2% to 2.6%). Isolated femoral vein thrombus was identified in 20 of 362 patients (5.5%; 95% CI 3.2% to 7.9%). Isolated deep femoral vein thrombus was found in 3 of 362 cases (0.8%; 95% CI –0.1% to 1.8%). -

FEMORAL INJECTING A GUIDE TO INJECTING IN THE GROIN USING THE FEMORAL VEIN (This is a restricted document NOT meant for general distribution) AUGUST 2006 1 INTRODUCTION INTRODUCTION This resource has been produced by some older intravenous drug users (IDU’s) who, having compromised the usual injecting sites, now inject into the femoral vein. We recognize that many IDU’s continue to use as they grow older, but unfortunately, easily accessible injecting sites often become unusable and viable sites become more dif- ficult to locate. Usually, as a last resort, committed IDU’s will try to locate one of the larger, deeper veins, especially when injecting large volumes such as methadone.

It starts the __________________________________________________________ electrical signal that travels across the upper 2 chambers or atria of the heart to the atrioventricular node (AV node). __________________________________________________________ The AV node transfers the electrical signal from the upper part of the heart to the lower 2 pumping chambers or ventricles.

ABSTRACT BACKGROUND The liability of the superficial venous system of the lower limbs to varicosity has naturally attracted the attention of Clinicians and Surgeons. Variations in the superficial veins of the lower limb are very common. The extent of such variations, their connections are usually described. Out of all the veins of the lower limb, the long saphenous and the small saphenous veins mark the major attraction clinically. Both the veins belong to superficial set of the veins, lie in the superficial fascia and possess valves. The long (great) saphenous vein, being the longest vein in the body, begins as a continuation of the medial marginal vein of the foot and ends in the femoral vein distal to the inguinal ligament. It ascends in front of the medial malleolus followed by passing obliquely across the medial surface of the tibia. In the upper part of the leg, it is accompanied by saphenous nerve and finally opens into the femoral vein after passing through the saphenous opening. The short saphenous vein can be the natural choice for coronary arterial bypass surgery, and also can be used in arterial reconstruction. The look for the variation in the termination of short saphenous vein should be taken into account before performing any varicose surgeries. -
Emergency Ultrasound” Presents Clinical Cases Involving the Diagnostic Use of Bedside Ultrasound in the Emergency Department

Ultrasonography of the Popliteal Vessels “PIPES” Last month, we began our posterior discussion of the final part of the RUSH protocol, the popliteal evaluation of the “pipes.” In vein that installment, we focused on ultrasound examination of the aortic artery. This month, as we conclude our series on RUSH, we continue our dis- cussion of the use of bedside marker ultrasound to evaluate the lateral “pipes”—specifically, to eval- uate the veins for deep vein popliteal thrombosis (DVT). In addi- artery tion, we demonstrate the util- ity of this exam in the hands of the emergency physician. anterior ULTRASOUND DETECTION OF LEG DVT Bedside ultrasonography for the detection of DVT of the leg is an advanced imaging study, but the necessary techniques are readily learned by emergency physicians who have an interest in sonography. The bedside exam comprises a two-point limited evaluation of the deep veins of the leg, with special attention to the proximal femoral vein and the popliteal vein. Elements of the more comprehensive, radiologist-performed exam are mentioned later in this article. Research has shown that the abbreviated bedside ultrasound evaluation of the leg retains excellent sensitivity in the diagnosis of DVT, while allowing for exam expediency.1 Veins have valves interspersed along their course, and most DVTs form in the areas behind the valves of the calf veins, where blood flow is often turbulent. Three smaller calf veins join together to form the popliteal vein, which lies just posterior to the knee joint in the popliteal fossa. -
Femoral Vein Duplication: Incidence and Potential Significance
Original article Femoral vein duplication: incidence and potential significance P Paraskevas Vein Health Medical Clinic, Melbourne, Australia Abstract Objective: The purpose of this study was to determine the prevalence of femoral vein duplication and the incidence of bilateral anomalies in a normal cohort of patients presenting with varicose veins. Methods: Two hundred and forty patients underwent bilateral lower limb deep venous ultrasound examination with particular attention to the femoropopliteal segment. Results: The incidence of femoral vein duplication was 41%. Of the 140 people with femoral vein duplications, 60 (42%) were bilateral and 80 (57%) were unilateral. Conclusion: Femoral vein duplication is a common anatomical variant of the lower limb deep venous system. Ultrasound in skilled and experienced hands with the latest ultrasound units can readily demonstrate this venous anomaly on a consistent basis. Keywords: femoral vein duplication; deep vein thrombosis; duplex ultrasound Introduction cases was also more frequently asymptomatic than in patients with a single femoral vein.
