Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

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 I: Introduction

A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...

Pulmonary Hypertension: Classification and Pathogenesis

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 Surgery
  • Thoracic Oncology
  • Vascular Pathology

Background:

  • Pulmonary artery intimal sarcoma is a rare and aggressive malignancy.
  • Diagnosis often presents challenges, with delayed identification impacting prognosis.
  • Advancements in medical imaging and clinical awareness are improving pre-operative diagnosis.

Observation:

  • A 72-year-old female patient presented with a mass originating in the right ventricle and extending into the pulmonary trunk and left pulmonary artery.
  • Computed tomography (CT) of the chest confirmed the presence and extent of the tumor.
  • The patient was deemed a candidate for surgical intervention.

Findings:

  • Complete surgical resection of the intimal sarcoma was achieved.
  • Repair of the pulmonary artery was performed concurrently with tumor removal.
  • Post-operative follow-up for 12 months showed no evidence of tumor recurrence.

Implications:

  • Aggressive surgical management is a viable and effective treatment strategy for pulmonary artery intimal sarcoma.
  • Early and accurate diagnosis, facilitated by advanced imaging, is crucial for successful surgical outcomes.
  • This case highlights the importance of surgical intervention in improving survival for patients with this rare tumor.
