Summary
Type 1A endoleak, a graft sealing issue, was successfully treated with coil embolization. This less-common method shows promise for managing endoleaks after endovascular aneurysm repair.
Area of Science:
- Vascular Surgery
- Interventional Radiology
Background:
- Type 1A endoleak occurs when the endograft fails to seal the proximal aneurysm neck, allowing blood flow between the aortic wall and graft.
- This complication affects 1.1% of patients within 30 days of endovascular aneurysm repair.
Observation:
- This article details a case study where coil embolization was utilized to treat a type 1A endoleak.
- A literature review of PubMed, LILACS, and SciELO databases was conducted for relevant studies published in the last five years.
Findings:
- Standard treatments for type 1A endoleak involve expanding the graft landing zone or increasing radial force.
- While other embolization agents like cyanoacrylate, fibrin glue, and Onyx have shown high success rates (>97%), coil embolization for type 1A endoleak is rarely documented.
Implications:
- Coil embolization presents a potentially effective, though infrequently reported, alternative for managing type 1A endoleaks.
- Further research and case reports are warranted to establish the efficacy and safety profile of coil embolization in this context.

543
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...

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

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...
