Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

102
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...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

103
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...

Imaging Studies for Cardiovascular System V: CT

131
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Area of Science:

  • Cardiology
  • Medical Imaging
  • Machine Learning

Background:

  • Total anomalous pulmonary venous connection (TAPVC) is a congenital heart defect.
  • Supracardiac TAPVC is a common subtype requiring surgical intervention.
  • Postoperative pulmonary venous obstruction (PVO) is a significant complication.

Purpose of the Study:

  • To establish a machine learning-based prediction model for PVO in supracardiac TAPVC.
  • To jointly utilize clinical data and CT images for improved prediction accuracy.
  • To evaluate the model's performance against traditional methods.

Main Methods:

  • Patients with supracardiac TAPVC (2009-2018) were retrospectively analyzed.
  • Clinical data features were selected using logistic regression.
  • CT image features were extracted using a convolutional neural network.
  • A joint prediction model integrated both data types, validated with fourfold cross-validation.

Main Results:

  • The study included 131 patients.
  • The machine learning-based joint method achieved the highest average AUC of 0.943.
  • The joint method demonstrated superior sensitivity (0.828) and positive predictive value (0.864) compared to traditional approaches.

Conclusions:

  • Jointly utilizing clinical data and CT images significantly enhances PVO prediction performance.
  • The proposed machine learning model demonstrates the effectiveness of multi-modality data integration.
  • This approach offers a practical tool for predicting PVO in TAPVC patients.
