BACKGROUND
Although the jugular vein is a major important blood vessel in equine, the literature lacks this vessel's normal B-mode and Doppler ultrasonographic examinations in donkeys. Therefore, this study aimed to determine the reference ranges of B-mode and Doppler ultrasonographic indices of jugular veins in healthy adult donkeys (Equus asinus) and the possible effect of examination side (left and right), gender, and body condition on the ultrasonographic measurements of this vessel. B-mode and Doppler ultrasound imaging of the external jugular vein was conducted on 20 adult healthy donkeys of both sexes.
RESULTS
In all donkeys, the jugular vein was 4.01 to 8.1 mm from the body surface. The longitudinal and transverse venous diameters ranged from 3.94 to 10.5 mm and from 0.88 to 1.9 cm, respectively. Moreover, the vein areas varied from 0.61 to 2.83 cm. The reference values of superficial and deep wall thickness (SWT and DWT) were 0.56 ± 0.2 and 0.6 ± 0.13 mm, respectively. The blood velocity, blood follow rate, and congestion index of the external jugular vein can be expected in adult healthy donkeys as a range value from 8.4 to 13.5 cm/sec, from 0.33 to 1.78 ml/min, and from 0.06 to 0.27 cm.sec, respectively. Generally, the vein showed laminar monophasic waveforms. The examination side and gender have no significant effect on the ultrasound measurements of the vein (P > 0.05). Donkeys with a body condition score (BCS) ≥ 3 revealed increases in the depth of the vein (P < 0.05).
CONCLUSIONS
The results of this study can be used as reference values and provide a basis for comparison when evaluating donkeys with diseases that affect blood flow in the external jugular vein.

BACKGROUND
This Obesity Medicine Association (OMA) Clinical Practice Statement (CPS) is intended to provide clinicians with an overview on obesity, thrombosis, venous disease, lymphatic disease, and lipedema.
METHODS
The scientific support for this CPS is based upon published citations, clinical perspectives of OMA authors, and peer review by the Obesity Medicine Association leadership.
RESULTS
Topics in this CPS include obesity, thrombosis, venous disease, lymphatic disease, and lipedema. Obesity increases the risk of thrombosis and cardiovascular disease via fat mass and adiposopathic mechanisms. Treatment of thrombosis or thrombotic risk includes healthful nutrition, physical activity, and the requisite knowledge of how body weight affects anti-thrombotic medications. In addition to obesity-related thrombotic considerations of acute coronary syndrome and ischemic non-hemorrhagic stroke, this Clinical Practice Statement briefly reviews the diagnosis and management of clinically relevant presentations of deep vein thromboses, pulmonary embolism, chronic venous stasis, varicose veins, superficial thrombophlebitis, lipodermatosclerosis, corona phlebectatica, chronic thromboembolic pulmonary hypertension, iliofemoral venous obstruction, pelvic venous disorder, post-thrombotic syndrome, as well as lymphedema and lipedema - which should be included in the differential diagnosis of other edematous or enlargement disorders of the lower extremities.
CONCLUSIONS
This Obesity Medicine Association (OMA) Clinical Practice Statement (CPS) on obesity, thrombosis, and venous/lymphatic disease is one of a series of OMA CPSs designed to assist clinicians in the care of patients with the disease of obesity.

On December 2020, the US Food and Drug Administration issued the first emergency use authorization for a vaccine for the prevention of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We report development of superficial thrombophlebitis in the ipsilateral breast of a 43-year-old female 7 days after receiving the first dose of the Pfizer-BioNTech COVID-19 vaccine. Given that this is the first case of superficial thrombophlebitis in the breast shortly after mRNA vaccination for COVID-19 reported to our knowledge, we suggest that this may be a rare vaccine-related event.

PURPOSE
Penile Mondor’s disease (superficial thrombophlebitis of the dorsal vein of the penis) is a rare clinical diagnosis. It is an easily diagnosed and treated disease. Nevertheless, when reviewing the literature, we considered that unnecessary tests are carried out for diagnosis. In this study, we aimed to indicate the redundancy of Doppler ultrasonography for diagnosis of penile Mondor’s disease.
MATERIALS AND METHODS
Seven patients with the clinical presentation of penile Mondor’s disease were included in the study. In the first two patients, penile Doppler ultrasonography was performed for diagnostic purposes by applying a vasoactive intracavernosal agent. This diagnostic procedure was not implemented in the next five patients.
RESULTS
Physical examinations revealed cord-like thickening lesions on dorsal and dorsolateral penis. In the first two patients, who penile Doppler ultrasonography with an intracavernosal vasoactive agent was used for diagnostic purposes, was developed priapism. We did not use penile Doppler for more patients as this would be unethical according to us.
CONCLUSION
Recovery from penile Mondor’s disease is usually spontaneous and smooth. A simple physical examination is sufficient for diagnosis, and palliative treatment is effective. For the diagnosis of this disease, unnecessary tests should be avoided so that patients are not harmed.

Journal of Thrombosis and Haemostasis :... Mar 2024Most family studies on venous thromboembolism (VTE) have focused on first-degree relatives.
BACKGROUND
Most family studies on venous thromboembolism (VTE) have focused on first-degree relatives.
OBJECTIVES
We took a pedigree-based approach and examined the risk of VTE and cardiometabolic disorders in offspring from extended pedigrees according to the densities of VTE in pedigrees.
METHODS
From the Swedish population, we identified a total of 482 185 pedigrees containing a mean of 14.2 parents, aunts/uncles, grandparents, and cousins of a core full sibship that we termed the pedigree offspring (n = 751 060). We then derived 8 empirical classes of these pedigrees based on the density of cases of VTE. The risk was determined in offspring for VTE and cardiometabolic disorders as a function of VTE density in their pedigrees. Bonferroni correction for multiple comparisons was performed.
RESULTS
VTE was unevenly distributed in the population; the Gini coefficient was 0.59. Higher VTE density in pedigrees was associated in the offspring with a higher risk of different VTE manifestations (deep venous thrombosis, pulmonary embolism, pregnancy-related VTE, unusual thrombosis, and superficial thrombophlebitis), thrombophilia, and lower age of first VTE event. Moreover, VTE density in pedigrees was significantly associated in the offspring with obesity, diabetes, gout, varicose veins, and arterial embolism and thrombosis (excluding brain and heart). No significant associations were observed for retinal vein occlusion, hypercholesterolemia, hypertension, coronary heart disease, myocardial infarction, ischemic stroke, atrial fibrillation, heart failure, primary pulmonary hypertension, cerebral hemorrhage, aortic aneurysm, peripheral artery disease, and overall mortality.
CONCLUSION
Offspring of pedigrees with a high density of VTE are disadvantaged regarding VTE manifestations and certain cardiometabolic disorders.

BACKGROUND
Thromboangiitis obliterans (TAO) or Buerger disease is a recurring progressive segmental vasculopathy that presents with inflammation and thrombosis of small and medium arteries and veins of the hands and feet. The exact cause remains unknown, with tobacco use (primarily smoking but also smokeless tobacco) being highly associated with the disease. The diagnosis is clinical and the lack of a diagnostic gold standard is a deterrent to diagnosing it in patients with atypical presentations. Obliterative endarteritis occurs perhaps due to a mixture of thrombosis and inflammation. The diagnostic sensitivity and specificity of D-dimer as a biomarker for thrombosis is well reported from its use in other areas such as deep vein thrombosis. Identification of a biomarker linked to the causation yields a diagnostic adjunct with a role in therapeutic decision-making, aiding diagnosis in atypical presentation, monitoring disease activity and gauging response to therapy.
METHODS
Between April 2014 and May 2015, we studied serum D-dimer (a marker of thrombosis) in 62 patients with TAO and compared this to 330 normal age- and sex-matched controls. We included all patients with peripheral arterial disease clinically diagnosed to have TAO according to the Shionoya criteria. There was no history of thrombosis or arterial disease in the control group. The control group was matched for baseline characteristics such as age and sex. All patients underwent a standard diagnostic protocol including blood tests (haemoglobin and creatinine), electrocardiogram, chest X-ray and ankle brachial pressure index. Blood was collected using an evacuated tube system into a citrate anticoagulant tube for testing D-dimer.
RESULTS
All the 62 patients diagnosed to have TAO were men with an average age of 40 years (range 18-65 years). They all had a history of tobacco use and did not have other atherogenic risk factors (part of the diagnostic criteria). Medium-vessel involvement was present in 53 patients (85%) and the rest presented with additional involvement of the popliteal and femoral vessels. Upper limb involvement or superficial thrombophlebitis was present in 95% of patients. Laboratory and imaging studies were consistent with TAO. The groups were well matched for age (p = 0.3). The median and interquartile range for D-dimer values were 61 ng/ml and 41-88 ng/ml in controls (n = 330) and 247 ng/ml and 126478 ng/ml in patients (n = 62), respectively (p<0.001).
CONCLUSIONS
D-dimer levels are considerably elevated in patients with TAO. This indicates an underlying thrombotic process and suggests its potential role as a diagnostic adjunct. It also leads us to hypothesize a potential therapeutic benefit of anticoagulants in this disease.

OBJECTIVE
Lower extremity venous aneurysms may lead to serious morbidity in patients, including pulmonary embolism (PE) and chronic venous insufficiency. Presently, because of the low incidence of these aneurysms, no consensus for their treatment exists. The purpose of this study was to review the presentation and management of lower extremity venous aneurysms at our institution.
METHODS
A retrospective review of all patients with isolated lower extremity venous aneurysms treated at a single tertiary care medical center from 2005 to 2017 was conducted.
RESULTS
Five male and six female patients with lower extremity venous aneurysms were identified, with a mean age of 50.4 years. Three patients presented with deep venous thrombosis or PE, three presented with pain, and five venous aneurysms were found incidentally. Nine of 11 patients had aneurysms involving the popliteal vein; one was in the iliac vein, and one was in the common femoral vein. Diagnosis was made by duplex ultrasound in five patients, magnetic resonance imaging in five patients, and computed tomography venography in one patient. Mean aneurysm to adjacent vein ratio was 2.62. No patients who had venous aneurysms discovered incidentally suffered thromboembolic complications. Three patients who were initially treated conservatively went on to eventual surgical intervention. Six patients underwent surgical intervention. The indication for operation was deep venous thrombosis or PE in three patients and lower extremity swelling in three patients; all were symptomatic at presentation. Three patients had simple venorrhaphy, two patients had aneurysmectomy and ligation of the vein, and one patient underwent aneurysmectomy with placement of an interposition vein graft. Mean follow-up was 26 months, with no recurrent thromboembolism. Perioperative complications included postoperative hematoma (one) and superficial thrombophlebitis (one).
CONCLUSIONS
Lower extremity venous aneurysms continue to represent a rare yet potentially morbid vascular disease. Symptomatic patients demonstrated a clear benefit from surgery vs conservative management. Larger, multicenter studies are required to properly characterize the natural history and management of this disease.
