Pulmonary Embolism I: Introduction

604
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Pulmonary Embolism III: Nursing Management

424
A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

Natural Selection and Mating Preferences01:06

Natural Selection and Mating Preferences

516
The principle of natural selection posits that organisms better adapted to their environment are more likely to survive and reproduce. This principle is closely intertwined with mating preferences, a key aspect of sexual selection, which evolutionary psychologists believe is driven by instincts to propagate one's genes. Such instincts significantly influence mating behaviors and preferences between genders.
Females, due to their biological roles in conception, pregnancy, and nursing,...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

388
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...

Frustration and Conflict: Approach-Approach, Approach-Avoidance

519
Frustration occurs when people are obstructed or prevented from achieving a desired goal or fulfilling a perceived need. For example, when someone's input is ignored in a discussion, it can lead to feelings of frustration. Conflict, however, arises from opposing interests, goals, or actions. Conflicts can take various forms based on the nature of these opposing desires or goals.
One common type of conflict is the Approach–Approach Conflict. In this case, a person faces two desirable...

Information Processing Approach01:30

Information Processing Approach

555
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Summary
This summary is machine-generated.

The transcaval approach offers a safe and effective method for managing type II endoleaks after aortic aneurysm repair. This technique successfully reduced endoleak sac size in 90% of patients, demonstrating its potential in endovascular repair management.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology

Background:

  • Type II endoleaks are a complication following endovascular repair of aortic aneurysms.
  • Persistent endoleaks can lead to sac enlargement and potential rupture.
  • Previous endovascular repair attempts may fail, necessitating alternative management strategies.

Purpose of the Study:

  • To evaluate the safety and efficacy of the transcaval approach for treating type II endoleaks.
  • To assess the impact of the transcaval approach on endoleak sac size and flow.
  • To determine the recurrence rate of endoleaks after transcaval intervention.

Main Methods:

  • A review of 10 consecutive patients with type II endoleaks after endovascular aneurysm repair.
  • Percutaneous transcaval access to the aorta using the Rösch-Uchida Transjugular Liver Access Kit.
  • Coil embolization of the endoleak sac and lumbar arteries, with optional use of gelatin and thrombin.

Main Results:

  • The transcaval approach was performed safely in all 10 patients.
  • A significant decrease in endoleak sac diameter was observed in 90% of patients.
  • Only one patient (10%) had persistent, though diminished, endoleak flow at follow-up.

Conclusions:

  • The transcaval approach is a safe and potentially efficient technique for managing type II endoleaks.
  • This method allows for direct access to the aortic sac via the vena cava.
  • The technique shows promise in reducing sac size and controlling endoleaks after endovascular aneurysm repair.
