Pulmonary Embolism I: Introduction

1.1K
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 Hypertension: Classification and Pathogenesis

812
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Area of Science:

  • Cardiovascular Pathology
  • Thoracic Oncology
  • Vascular Tumors

Background:

  • Pulmonary artery intimal sarcomas are rare, aggressive malignant tumors.
  • These tumors often affect major blood vessels like the aorta, vena cava, and pulmonary arteries.
  • Symptoms and imaging can resemble pulmonary thromboembolism, complicating diagnosis.

Observation:

  • The case involved a 72-year-old African-American male.
  • The patient presented with arterial intimal sarcoma affecting both the left and right pulmonary arteries.
  • Tumor extension into the bronchus and right lung was noted.

Findings:

  • Pulmonary artery intimal sarcomas present with symptoms like chest pain and dyspnea.
  • Obstructive tumor effects can lead to pulmonary hypertension and right ventricular failure.
  • Differential diagnosis must include intimal sarcoma for patients with pulmonary artery filling defects.

Implications:

  • Highlights the importance of considering intimal sarcoma in the differential diagnosis of pulmonary artery obstructions.
  • Emphasizes the aggressive nature and potential for extensive local invasion.
  • Underscores the need for prompt recognition and management of these rare tumors.
