All endovascular procedures need an effective anticoagulation regimen that avoids thrombo-embolic complications due to the insertion and manipulation of various intravascular devices. Systemic heparinization reduces the risk of thrombosis but there is no conclusive evidence regarding the correct use of anticoagulant medications and accordant monitoring, especially in endovascular peripheral arterial procedures. Anticoagulation must be maintained during the whole vascular procedure, especially during partial or complete blood flow interruption. Reaching and maintaining the correct coagulative status is mandatory to avoid or reduce thromboembolic complications that could limit the procedure's effectiveness or be harmful to the patient. Patients' baseline variables and procedure-related elements can influence the way anticoagulation should be administered and how coagulative status has to be monitored. This review aimed to clarify the critical points of anticoagulation and monitoring management for non-cardiac arterial procedures in order to understand the best way to manage vascular procedures anticoagulation.

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Venous Thrombosis III: Interprofessional Care

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...

Clot Retraction and Fibrinolysis01:16

Clot Retraction and Fibrinolysis

After a fibrin clot is formed, the next step is clot retraction, a vital process facilitated by platelet contractile proteins, such as actin and myosin. These proteins pull the fibrin strands closer together and condense the clot. This action reduces the size of the clot, creating a smaller, denser structure that effectively seals off the damaged vessel. Clot retraction consolidates the clot and helps with wound healing by bringing the edges of the damaged blood vessel closer together.

Extrinsic and Intrinsic Pathways of Hemostasis01:20

Extrinsic and Intrinsic Pathways of Hemostasis

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...
