Abstract:

脾動脈仮性動脈瘤（SAP）は、破裂のリスクが高く、炎症性血管病変に伴う可能性がある生命を脅かす血管病変である。SAPに対する血管内治療としては経カテーテル塞栓術が最も一般的であるが、カバードステント留置術は動脈の開通性と脾血流を維持できる。しかし、十分なランディングゾーンの欠如や血管の過度な蛇行などの解剖学的制約による制限がある。本症例報告では、全身性エリテマトーデスにIII型クリオグロブリン血症を合併し、生検で白血球破砕性血管炎が証明されており、壊死性膵炎を呈した患者に対し、SAPのステント留置術を成功させた際の臨床的および技術的な検討事項について述べる。

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.
