Venous Thrombosis III: Interprofessional Care01:29

Venous Thrombosis III: Interprofessional Care

459
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

283
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...

Peripheral Artery Disease III: Interprofessional Care

543
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...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

633
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

326
Hemoperfusion and hemofiltration are critical techniques in medical treatments to eliminate accumulated drugs, metabolites, and electrolytes from the bloodstream. These methods are particularly vital in cases of accidental poisoning and drug overdose.Hemoperfusion involves passing blood through an adsorbent material to remove unwanted substances. The main adsorbents used in hemoperfusion include activated charcoal and Amberlite resins. Activated charcoal can adsorb both polar and nonpolar...

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy01:26

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

336
Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in...

Area of Science:

  • Interventional Radiology
  • Vascular Surgery
  • Medical Device Retrieval

Background:

  • Dislocated intravascular foreign bodies pose a significant clinical challenge.
  • Timely and safe retrieval is crucial to prevent complications.
  • Traditional surgical removal can be invasive and associated with higher risks.

Purpose of the Study:

  • To evaluate the technical success rate of percutaneous extraction for dislocated intravascular foreign bodies.
  • To assess the complication rate associated with these interventional procedures.
  • To determine the efficacy of interventional therapy in avoiding surgical intervention.

Main Methods:

  • A retrospective analysis of 38 patients (1999-2015) undergoing extraction of intravascular foreign bodies.
  • Foreign bodies included various devices like port catheters, dialysis catheter tips, stents, and guide wires.
  • Transarterial and transvenous access routes were utilized with various catheters for repositioning and extraction.

Main Results:

  • A high technical success rate of 92.1% (35 of 38 patients) was achieved.
  • In 17 patients, additional catheters were needed for repositioning prior to extraction.
  • Two cases were unsuccessful due to stent remodeling and distal pulmonary artery fragment dislocation; one guide wire could not be extracted due to adherence.

Conclusions:

  • Percutaneous extraction of dislocated intravascular foreign bodies is a technically successful and safe procedure.
  • Interventional therapy offers a viable alternative to surgical removal, minimizing patient invasiveness.
  • The gooseneck-snare catheter was frequently employed and effective in these retrieval procedures.
