Summary
Pulmonary arteriovenous malformation (PAVM) can lead to rare splenic complications like infarction and abscess. Early embolization of PAVM is crucial to prevent serious systemic issues.
Area of Science:
- Vascular Medicine
- Interventional Radiology
- Gastroenterology
Background:
- Pulmonary arteriovenous malformations (PAVMs) are abnormal vascular connections between pulmonary arteries and veins.
- PAVMs can cause paradoxical emboli, leading to systemic complications.
- Splenic infarction and abscess are rare but serious consequences of PAVMs.
Observation:
- A 66-year-old woman presented with worsening dyspnea and was found to have a PAVM.
- Despite prior detection, the patient delayed further investigation of her PAVM.
- She developed splenic infarction and abscess, attributed to the PAVM.
Findings:
- Detailed examinations confirmed splenic infarction and abscessation secondary to the PAVM.
- PAVM embolization was successfully performed following antibiotic treatment for the splenic abscess.
- This case highlights the rare but severe splenic complications associated with PAVMs.
Implications:
- Prompt embolization of PAVMs, regardless of size, is recommended to mitigate risks.
- Early intervention can prevent not only neurological complications but also rare splenic events.
- This underscores the importance of timely diagnosis and management of PAVMs.

965
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...

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...

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...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
