Venous Thrombosis III: Interprofessional Care01:29

Venous Thrombosis III: Interprofessional Care

471
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...

Esophageal Varices-II: Clinical Features and Management

820
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Extrinsic and Intrinsic Pathways of Hemostasis01:20

Extrinsic and Intrinsic Pathways of Hemostasis

15.9K
Blood clotting or coagulation involves extrinsic and intrinsic pathways, which ultimately merge into the common pathway, forming a fibrin clot.
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

Coagulation01:09

Coagulation

12.3K
The coagulation phase is a critical part of the body's process to prevent blood loss following injury to blood vessels. It involves chemical reactions that form a clot to seal the injured area. The clotting process begins shortly after injury, within 15-20 seconds for severe damage and 1-2 minutes for minor injuries.
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...

Venous Thrombosis I: Introduction

732
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...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

2.5K
Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Malignancy does not dictate the hypercoagulable state following liver resection.

Summary

Malignancy status does not affect coagulation profiles after liver resection. Postoperative coagulopathy, not cancer, likely causes a temporary hypercoagulable state, indicated by thromboelastogram (TEG) changes.

Area of Science:

  • Hepatobiliary Surgery
  • Surgical Oncology
  • Coagulation Medicine

Background:

  • Intra-abdominal malignant resections are associated with a hypercoagulable state.
  • The cause of this hypercoagulability—the surgery itself or the malignancy—is unclear.
  • Liver resection is a common procedure where this phenomenon is observed.

Purpose of the Study:

  • To determine if malignancy status influences the coagulation profile after liver resection.
  • To compare perioperative thromboelastogram (TEG) values between patients undergoing resection for benign versus malignant liver disease.

Main Methods:

  • Retrospective review of prospectively collected TEG data.
  • Analysis of TEG values in patients who underwent liver resection.
  • Comparison of coagulation parameters between patients with benign and malignant disease.

Main Results:

  • No significant differences in TEG values were found between patients with benign and malignant liver disease.
  • A mild hypercoagulable state was observed postoperatively in the combined patient group, characterized by decreased R-times.
  • Postoperative TEG values remained within normal clinical ranges despite statistical significance.

Conclusions:

  • Malignancy status does not appear to be a significant factor in the coagulation changes observed after liver resection.
  • The development of a relative hypercoagulable state following liver resection is more likely attributable to postoperative coagulopathy.
  • These findings suggest that the surgical impact on coagulation is a primary driver, irrespective of the underlying disease pathology.
