Thoracic Aorta01:15

Thoracic Aorta

1.5K
The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...

The Thoracic Cage: Sternum

5.7K
The thoracic or rib cage forms the body's thorax (chest) portion. Its primary function in the body is to protect vital organs in the thoracic cavity, such as the heart and the lungs. It consists of 12 pairs of ribs with their costal cartilages and the sternum. The ribs are anchored posteriorly to the 12 thoracic vertebrae (T1-T12).
The sternum is the elongated bony structure on the anterior side of the thoracic cage. It consists of three parts: the manubrium, the body, and the xiphoid...

The Thoracic Cage: Ribs

8.2K
Ribs are curved, flattened bones forming the thoracic cavity wall with the thoracic muscles. There are 12 pairs of thoracic ribs. The posterior ends of all the ribs articulate with the T1–T12 thoracic vertebrae. In contrast,the anterior ends of most ribs attach to the sternum via their costal cartilages.
Parts of a Typical Rib
A typical rib has a head, neck, and body. The posterior end of the rib is called the head, followed by a narrow neck. The head articulates primarily with the costal...

Pressure Relationships in Thoracic Cavity01:24

Pressure Relationships in Thoracic Cavity

6.0K
Breathing, otherwise known as pulmonary ventilation, is the process of air movement into and out of the lungs. The main mechanisms propelling pulmonary ventilation are atmospheric pressure (Patm), intra-pulmonary (Ppul ) or intra-alveolar pressure (Palv) within the alveoli, and intrapleural pressure (Pip) within the pleural cavity.
Breathing Mechanisms
Both intra-alveolar and intrapleural pressures rely on specific lung properties. The ability to breathe—allowing air to enter the lungs...

Self-Evaluation: Self-Enhancement and Self-Verification

5.7K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Nursing Evaluation01:15

Nursing Evaluation

4.2K
The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.

Summary

Thoracic cancer patients show increased blood clot risk. Rotational thromboelastometry (ROTEM) revealed hypercoagulable profiles in lung and esophageal cancer patients, with differing changes after surgery.

Area of Science:

  • Oncology
  • Hematology
  • Surgical Research

Background:

  • Venous thromboembolism (VTE) risk is elevated in thoracic malignancies.
  • Coagulation patterns in these patients remain incompletely understood.
  • Rotational thromboelastometry (ROTEM) offers advanced assessment of coagulation.

Purpose of the Study:

  • To investigate and compare pre- and postoperative coagulation profiles in patients with esophageal and lung cancer.
  • To determine if thoracic malignancy patients exhibit similar hypercoagulable states using ROTEM.
  • To assess the impact of surgical resection on coagulation in these patient groups.

Main Methods:

  • A prospective study involving 47 patients undergoing surgical resection for esophageal or lung cancer.
  • Rotational thromboelastometry (ROTEM) was employed to evaluate coagulation status before and after surgery.
  • Conventional coagulation tests were used for comparison.

Main Results:

  • Patients with thoracic malignancy demonstrated hypercoagulability via ROTEM, not conventional tests.
  • Preoperative hypercoagulability was significantly higher in lung cancer (64%) versus esophageal cancer (16%).
  • Lung cancer surgery reversed preoperative hypercoagulability, while esophageal cancer surgery induced it, linked to platelet activity.

Conclusions:

  • Hypercoagulability in lung cancer reversed post-surgery; in esophageal cancer, it emerged post-surgery.
  • Both cancer types showed persistent hypercoagulability at follow-up, associated with fibrin and platelet function.
  • ROTEM provides critical insights into distinct coagulation changes in lung versus esophageal cancer.
