Summary
The incidence of venous thrombosis associated with peripherally inserted central catheters (PICCs) is low. Using the smallest possible catheter diameter can help reduce the risk of developing this complication.
Area of Science:
- Vascular Surgery
- Medical Devices
- Thrombosis Research
Background:
- Peripherally inserted central catheters (PICCs) are widely used for long-term venous access.
- Catheter-related thrombosis is a potential complication that can lead to significant morbidity.
Purpose of the Study:
- To identify risk factors associated with venous thrombosis in patients who have PICCs.
- To evaluate the relationship between various factors and the development of PICC-related thrombosis.
Main Methods:
- A retrospective review of 813 PICCs placed in 678 patients between January and December 1997.
- Cross-referencing medical records with 1,631 venous duplex examinations performed during the same period.
- Analysis of factors including diagnosis, infusate, catheter tip position, vein accessed, and catheter diameter.
Main Results:
- The overall rate of PICC-associated venous thrombosis was 3.9%.
- Catheter diameter was the only statistically significant factor identified in multivariate analysis.
- No thromboses occurred with catheters ≤3 French (F); rates increased with larger diameters: 1% for 4-F, 6.6% for 5-F, and 9.8% for 6-F.
Conclusions:
- The incidence of venous thrombosis related to PICCs is low.
- Selecting the smallest appropriate catheter diameter is crucial for minimizing the risk of thrombosis.

01:27Parentral Nutrition: Centeral and Peripheral Parental Nutrition
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
01:30Venous Thrombosis I: Introduction
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...
01:20Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
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...
01:29Venous 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...
01:30Venous Thrombosis IV: Nursing Management
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,...
