Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

760
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...

Varicose Veins II: Diagnostic Studies and Interprofessional Care

325
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 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...

Esophageal Varices-II: Clinical Features and Management

893
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...

Peripheral Artery Disease III: Interprofessional Care

659
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...

Summary

Supplementary transcatheter arterial embolization (STAE) after endoscopic hemostasis may help prevent rebleeding in high-risk peptic ulcer bleeding (PUB) patients. While not statistically significant, STAE showed a trend towards reduced rebleeding rates in this study.

Area of Science:

  • Gastroenterology
  • Interventional Radiology
  • Clinical Trials

Background:

  • Peptic ulcer bleeding (PUB) poses a significant mortality risk, primarily due to rebleeding.
  • Endoscopic hemostasis is standard, but rebleeding remains a critical challenge in high-risk PUB patients.

Purpose of the Study:

  • To evaluate the efficacy of supplementary transcatheter arterial embolization (STAE) in reducing rebleeding rates after endoscopic hemostasis in high-risk PUB.
  • To assess the impact of STAE on mortality, transfusion requirements, and hospital stay in PUB patients.

Main Methods:

  • A non-blinded, randomized controlled trial comparing STAE versus standard treatment in 105 PUB patients with Forrest Ia-IIb ulcers.
  • Patients were randomized 1:1 after successful endoscopic hemostasis, stratified by stigmata of hemorrhage.
  • Follow-up was for 30 days, with a composite primary endpoint including transfusion, rebleeding, re-intervention, and mortality.

Main Results:

  • No significant difference was observed in the composite endpoint between the STAE and control groups.
  • Two patients in the STAE group and eight in the control group experienced rebleeding (p = .10).
  • A trend towards reduced rebleeding was noted with STAE after adjustment for imbalances (p = .079).

Conclusions:

  • STAE shows potential as an adjunct therapy to prevent rebleeding in selected high-risk PUB patients.
  • The procedure was safely performed in patients with a high risk of rebleeding.
  • Further research is necessary to confirm the benefits of STAE in managing high-risk PUB.
