Background: Venous return from the lower extremities is pumped upwards to the right side of the heart in a process that is facilitated by one-way valves and the venous muscle pump, of which the calf muscle pump is a major contributor1-3. Venous plethysmography can quantitatively assess calf pump function (CPF). The association between the CPF and venous thromboembolism (VTE) has not been investigated. Methods: Venous plethysmography (VP) data (strain gauge or air plethysmography) from the Mayo Clinic Vascular Lab database (1998-2015) of CPF (bilaterally reduced, unilaterally reduced, and bilateral normal) were examined in Olmsted County Residents. The Rochester Epidemiology Project (REP) captures the population of Olmsted County and contains demographic information, medical diagnoses, hospital admissions, and surgical procedures as well as validated VTE events and death. Patients with signs of obstructed outflow in either extremity on the venous plethysmography (a possible sign of acute or chronic deep vein thrombosis) study were excluded. Patients with a history of VTE diagnosed before the physiologic study were also excluded. If more than one measurement of calf muscle pump function was performed, only the first measurement was used. The primary outcome was a composite of any VTE, including proximal and distal deep vein thrombosis (DVT) and pulmonary embolism (PE). Results: 1703 Olmsted County residents had venous plethysmography studies performed. MN research authorization was denied in 64 patients and 107 were excluded for any documented VTE preceding index VP study. 1532 patients with recorded CPF (28% air and 72% strain gauge plethysmography) were studied: 591 (38.5%) had normal CPF, 353 (23.0%) had unilateral reduced CPF (rCPF), and 588 (38.3%) had bilateral rCPF. The mean age was 64.4 (SD 18.4), 68.9% were female, and the mean BMI was 29.5 (SD 6.4). Any VTE occurred in 87 patients (5.7%) after a mean follow up of 10.9 years (range 0-22.0 years). Isolated lower extremity DVT (excluding concurrent PE) occurred in 49 patients and PE+/-DVT occurred in 38 patients. Death occurred in 352 patients (23%). Bilateral rCPF compared to bilateral normal CPF was associated with VTE (p=0.007), DVT only (p=0.02) and death (p<0.001) but not PE+/-DVT (p=0.13). Unilateral rCPF compared to bilateral normal CPF was not associated with VTE, but was associated with death (p<0.001). Kaplan-Meier curves for VTE and death are shown in Figure 1. The hazard ratio for bilateral rCPF compared to bilateral normal CPF for VTE was 2.0 (95% CI 1.2-3.4) and for DVT only was 2.2 (95% CI 1.1-4.2). A sensitivity analysis for the main outcome of VTE did not show significant interaction based on the type of plethysmography (strain vs. air), by age stratified at 65 years, sex, or BMI stratified at 30 (p>0.1 for each comparison). Conclusion: In this population-based study of Olmsted County residents with no prior VTE, rCPF function as measured by venous plethysmography is associated with increased risk for VTE, particularly lower extremity proximal DVT. More research is required to understand what additional measures of venous physiology influence these findings and whether CPF could be used in VTE risk stratification.

In order to quantitatively evaluate calf muscle pump function following deep vein thrombosis (DVT), expelled volume was investigated by strain gauge plethysmography (SPG). Thirty-six patients with 43 diseased lower limbs and nine healthy persons with 16 control limbs were studied. Of 43 diseased limbs, 20 symptomatic limbs were distinguished from 23 asymptomatic limbs by the presence of heaviness or aching. The following ***noninvasive parameters for the quantitative evaluation of calf muscle pump function, venous refilling time (VRT), venous outflow (VO), venous return (VR), and expelled volume (EV) were measured by SPG or photoplethysmography (DPG). Ambulatory venous pressure (AVP) was taken to represent the standard for calf muscle pump function. Using SPG, the EV, VR, and VRTs distinguished three groups (control, asymptomatic and symptomatic). Among seven indicators (EV, VR, VO, VRTs), EV had the highest correlation coefficient with the AVP ( r = +0.728). A positive EV was present in 85% of the symptomatic limbs, but in only 4% of the asymptomatic limbs. It is concluded that the EV is a useful non-invasive indicator for the quantitative evaluation of calf muscle pump function after deep vein thrombosis.

Objective: To evaluate accurately the calf muscle pump in patients with venous insufficiency using foot vein pressure measurements during three different exercises. Design: Prospective study in three groups, comparing patients with venous disease with controls. Setting: Second Department of Surgery, Tottori University Faculty of Medicine. Patients: Twenty normal legs, 29 legs previously affected by deep vein thrombosis and 36 legs with primary varicose veins. Main outcome measures: The foot vein pressure was measured during ankle dorsiflexions, knee-bending and walking on the spot at 40 paces per minute during which minimum ambulatory venous pressure (AVP) and venous refilling time (VRT) were assessed. Results: The three groups differed significantly from each other in AVP and VRT after dorsiflexion and in AVP during walking on the spot, but not after knee-bending. Conclusion: Dorsiflexion is the most useful exercise distinguishing various severities of venous insufficiency, but walking on the spot is more useful for accurately evaluating the calf muscle pump.

Calf muscle trauma commonly involves the gastrocnemius and soleus muscles. Plantaris muscle is a vestigial muscle coursing through the calf. Similar clinical features may be seen with injury to the plantaris muscle. It can also mimic other conditions like deep vein thrombosis, rupture of Baker's cyst, and tumors. MRI is helpful in identifying and characterizing it. We report two cases of ruptured plantaris muscle seen on MRI.

Objective: This study was designed to determine the optimal physical methods for promoting venous return of the leg. Methods: Ten healthy volunteers were investigated in the supine position on a couch, and their peak femoral venous velocity and calf muscle volume were determined using duplex ultrasound and strain gauge plethysmography,respectively,before and during deep respiration, limb elevation, calf squeezing and various types of leg exercises. Results: Deep respiration showed the smallest effect on both percentage increase of peak flow velocity and expelled volume. Elevation of the leg showed the same effect on the expelled volume as calf muscle squeezing and ankle movement, while the former showed significantly less effect than the latter on the percentage increase of peak flow velocity. In both dorsal flexion of the ankle and squeezing at the calf, the stronger of each procedure caused more effective changes in haemodynamics. Ankle exercise was more effective in promoting venous return in the calf muscle than wiggling the toes, making circling movements with the feet or alternately flexing and spreading the toes. Conclusions: Ankle exercise or calf muscle squeezing, performed maximally,may be the first recommendation for reducing venous stasis at the calf muscle and prophylaxis of deep vein thrombosis..

Background and purposeValid and reliable measurements are paramount to advance the science of intensive care unit (ICU) nursing. This study aimed to evaluate the reliability and construct validity of the Nurses' Intention to Use Deep Vein Thrombosis Preventive Measures Questionnaire among critically ill patients in an Egyptian ICU. A crosssectional, predictive design pilot-tested the psychometric properties of the questionnaire in a convenience sample of 78 RNs working in ICU.MethodsConstruct validity was examined using factor analysis.ResultsThe Kaiser–Meyer–Olkin measure of sampling was 0.71, and Bartlett's test of sphericity was significant (X2 = 410.16, p < .05). Four factors were identified through factor analysis. Cronbach's α assessed the internal consistency reliability with a value of .82.ConclusionOur analyses showed that the Nurses' Intention to Use Deep Vein Thrombosis Preventive Measures Questionnaire has good validity and reliability; however, further investigations will be completed.
