Venous Thrombosis III: Interprofessional Care01:29

Venous Thrombosis III: Interprofessional Care

482
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...

Varicose Veins II: Diagnostic Studies and Interprofessional Care

319
Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Venous Thrombosis IV: Nursing Management

412
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,...

Venous Thrombosis I: Introduction

808
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...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

466
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...

Varicose Veins I: Introduction01:26

Varicose Veins I: Introduction

378
Varicose veins, or varicosities, are abnormally dilated and twisted superficial veins caused by venous valve incompetence. This condition commonly affects the lower extremities, especially the saphenous veins, due to the higher pressure from prolonged standing and walking. However, varicosities can also occur in other areas, such as the esophagus, vulva, spermatic cords, and anorectal region.Etiology and typesPrimary varicose veins, often idiopathic, are more common in women due to inherent...

Summary

Photodynamic therapy (PDT) effectively treats chronic venous ulcers. This study found PDT healed 78.9% of refractory ulcers, offering a promising alternative treatment option.

Area of Science:

  • Dermatology
  • Vascular Medicine
  • Photomedicine

Background:

  • Chronic venous ulcers are a significant clinical challenge.
  • Limited effective treatments exist for refractory cases.
  • Photodynamic therapy (PDT) shows potential based on prior findings.

Purpose of the Study:

  • To evaluate the efficacy of PDT for refractory chronic venous ulcers.
  • To determine healing rates and treatment outcomes with PDT.

Main Methods:

  • Nineteen patients with refractory chronic venous ulcers were enrolled.
  • Treatment involved photodynamic therapy.
  • Outcomes were assessed based on ulcer healing and improvement.

Main Results:

  • Fifteen out of 19 patients (78.9%) achieved complete ulcer healing.
  • Healing occurred after an average of 6.8 PDT sessions.
  • The remaining four patients showed marked improvement after 10 sessions.

Conclusions:

  • Photodynamic therapy is a viable and effective treatment for refractory chronic venous ulcers.
  • PDT offers a good alternative therapeutic option for this patient group.
  • Further research can explore PDT's role in venous ulcer management.
