Insights

Pulmonary artery pseudoaneurysms (PAPs) are rare but serious, often causing hemoptysis. This case highlights successful coil embolization for an infectious PAP in an elderly patient, improving outcomes.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Pulmonary Medicine

Background:

  • Pulmonary artery pseudoaneurysms (PAPs) are infrequent vascular lesions with high morbidity and mortality.
  • PAPs often present with life-threatening hemoptysis, necessitating prompt diagnosis and intervention.

Observation:

  • An 87-year-old male presented with hemoptysis, initially diagnosed with a lung abscess.
  • Contrast-enhanced chest CT revealed an infectious pulmonary artery pseudoaneurysm in the left lower lobe.

Findings:

  • Pulmonary artery coil embolization was successfully performed on the ninth hospital day.
  • The intervention led to significant clinical improvement in the patient's condition.

Implications:

  • This case underscores the efficacy of endovascular treatment for infectious PAPs.
  • Early diagnosis and interventional radiology techniques can improve outcomes in patients with PAPs and hemoptysis.

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 II: Diagnostic Studies and Interprofessional Care

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...

Pulmonary Embolism III: Nursing Management

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...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
Pneumothorax II: Pathophysiology01:08

Pneumothorax II: Pathophysiology

Pneumothorax means the presence of air in the pleural space — the thin potential gap between the visceral and parietal pleura. This condition disrupts the normal pressure balance that keeps the lungs inflated, leading to partial or complete collapse of the affected lung.Normal physiologyUnder normal conditions, the pleural space maintains a slightly negative intrapleural pressure, which keeps the lungs expanded against the chest wall. This negative pressure creates a delicate balance between...

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...
