Summary
Upper limb venous thrombosis (ULVT) is frequently linked to endovenous devices. While symptomatic pulmonary embolism (PE) is uncommon, underlying conditions like malignancy and sepsis are prevalent in ULVT patients.
Area of Science:
- Vascular Medicine
- Thrombosis Research
- Diagnostic Imaging
Background:
- Upper limb venous thrombosis (ULVT) is a condition requiring thorough clinical evaluation.
- Understanding the clinical features and underlying causes of ULVT is crucial for patient management.
- Doppler ultrasonography is the primary diagnostic tool for suspected ULVT.
Purpose of the Study:
- To delineate the clinical characteristics of upper limb venous thrombosis (ULVT).
- To identify the primary etiologies and associated conditions in patients diagnosed with ULVT.
- To evaluate the diagnostic accuracy of clinical symptoms for ULVT.
Main Methods:
- Retrospective analysis of 488 patients with suspected ULVT from January to December 2016.
- Diagnosis confirmed via Doppler ultrasonography.
- Analysis of clinical features, thrombosis location, symptomatic pulmonary embolism (PE), and associated risk factors.
Main Results:
- 160 patients were diagnosed with ULVT (80 deep venous thrombosis [DVT], 80 superficial venous thrombosis [SVT]).
- Endovenous devices were present in 92.5% of ULVT cases (87.5% DVT, 97.5% SVT).
- Malignancy (43.8% DVT, 31.3% SVT), sepsis (25%), and solid neoplasia (15%) were common comorbidities. Symptomatic PE occurred in 2.5% of cases.
Conclusions:
- Endovenous devices are strongly associated with the development of ULVT.
- The incidence of symptomatic pulmonary embolism in ULVT is notably low.
- Hematological malignancies, sepsis, and neoplasia are significant underlying conditions in patients with ULVT.

01:30Venous Thrombosis I: Introduction
474
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

348
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

373
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

The circulatory system plays a crucial role in ensuring the optimal functioning of the human body. One of its critical components is venous return - the process that completes the blood circulation cycle. This article will delve into the concept of venous return, how it works, and its significance to our health.
What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...

01:22Absolute and Local Extreme Values
84
The highest and lowest values of a function, relative to a reference axis, are known as extreme values. These include absolute maximum and absolute minimum values, which represent the highest and lowest points the function reaches across its entire domain. Within a restricted portion of the function, the highest and lowest values are referred to as local maximum and local minimum values, respectively.Periodic functions, such as sine and cosine, show extreme values at infinitely many points due...
