Mesenteric Vascular Disease Flashcard Deck - 9 Cards
Flashcard 1: The most common artery involved in PVD is the _____ artery
Answer: superficial femoral
Flashcard 2: What is the most common cause of an acute mesenteric ischemia?_____
Answer: Embolus
Flashcard 3: _____ mesenteric ischemia may occur due to a thrombotic or embolic occlusion of the superior mesenteric artery
Answer: Acute
Flashcard 4: In the 2020 update of the CEAP classification, what is the **pathophysiologic (P) component** for a patient with venous obstruction?
Answer: Po
Extra: The CEAP classification (updated in 2020) is the international standard for describing chronic venous disorders:
- **C**linical classification (C0–C6): C6 denotes an active venous ulcer.
- **E**tiologic classification (Ep, Es, Ec, En): Es stands for secondary (e.g., post-thrombotic).
- **A**natomic classification (As, Ad, Ap, An): d = deep, s = superficial, p = perforator.
- **P**athophysiologic classification (**Pr, Po, Pr,o, Pn**): **Po** stands for **obstruction**.
The 2020 update introduced further refinements (like Esi for intravenous and Ese for extravenous secondary causes) but the basic abbreviation for Pathophysiologic Obstruction remains **Po**.
Flashcard 5: Aortic aneurysm may cause _____ and/or back pain, which is a sign of leaking, dissection, or imminent rupture
Answer: abdominal
Flashcard 6: The _____ internal mammary artery is the preferred vessel for coronary artery bypass grafting (CABG).
Answer: left
Extra: The **Internal Mammary Artery (IMA)** is also known as the **Internal Thoracic Artery (ITA)**.
The **Left Internal Mammary Artery (LIMA)** is the preferred conduit for CABG (especially when bypassing the Left Anterior Descending [LAD] artery) because of its superior long-term patency (>90% at 10 years) compared to saphenous vein grafts.
Flashcard 7: Abdominal aortic aneurysm rupture presents with a triad of _____, a pulsatile abdominal mass, and flank pain
Answer: hypotension
Flashcard 8: Treatment of Moyamoya disease: Surgical bypass of _____ arteries to the dura or middle cerebral artery
Answer: extracranial carotid
Extra: Revascularization procedures for Moyamoya disease:
- **Direct bypass**: e.g., STA-MCA bypass (Superficial Temporal Artery to Middle Cerebral Artery).
- **Indirect bypass (Synangiosis)**: e.g., EDAS (Encephaloduroarteriosynangiosis), where the STA is placed in contact with the brain surface.
Flashcard 9: Stanford type _____ dissections, involving both the ascending and descending aorta are also classified as DeBakey type I
Answer: A
