Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care01:29

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

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 Care01:26

Varicose Veins II: Diagnostic Studies and Interprofessional Care

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

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...

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

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...
Esophageal Varices-II: Clinical Features and Management01:28

Esophageal Varices-II: Clinical Features and Management

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 abuse, or...

Summary

Hemipelvectomy for pelvic tumors has advanced significantly since 1891. Modern techniques improve outcomes, but multimodal collaboration remains crucial for survival in these challenging cancer surgeries.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Reconstructive Surgery

Background:

  • Pelvic tumors present significant surgical challenges.
  • Hemipelvectomy, first performed in 1891, is a critical intervention for rare malignant bone and soft tissue tumors.
  • Interdisciplinary therapy is essential for curative attempts, despite risks of bleeding and infection.

Purpose of the Study:

  • To present a selective literature review on hemipelvectomy.
  • To outline the history, indications, treatment options, and outcomes of hemipelvectomy.
  • To highlight the importance of advancements in diagnosis, surgical technique, and adjuvant treatment.

Main Methods:

  • Selective literature review.
  • Analysis of historical and current treatment modalities for pelvic tumors requiring hemipelvectomy.
Keywords:

  • Evaluation of outcomes including recurrence rates and survival.

    • Main Results:

    • Significant advances in preoperative diagnosis, surgical technique, and adjuvant therapies have been made.
    • Reconstruction using microvascular free flaps or local rotational flaps has improved outcomes and reduced infection rates.
    • Average local recurrence rates are 14%, with 5-year survival rates around 50% for certain tumor types, underscoring the need for multimodal approaches.

    Conclusions:

    • Hemipelvectomy remains a challenging but potentially curative option for pelvic tumors.
    • Reconstructive surgery plays a vital role in patient quality of life post-hemipelvectomy.
    • Multimodal collaboration is essential for optimizing survival rates in patients undergoing hemipelvectomy for pelvic malignancies.
