Merge from Coronary artery dissection

This article already covers dissecting aneurysms (when caused by angioplasty procedures). Just created is Coronary artery dissection, but the only term I've encountered would be Coronary artery aneurysm, which already exists. The ICD10 name I25.4 follows this, indeed it fails even give "Coronary artery dissection" as a synonym. In the absence of a preference in the medical literature (PubMed: 535 "Coronary artery aneurysm" vs 547 "Coronary artery dissection") then, per WP:MEDMOS, we usually defer to the WHO name.

Now I appreciate there is a difference between just a dilation (swelling), from when there might be an extending tear. Hence an aneurysm may rupture the vessel entirely (eg with subarachnoid haemorrhages from berry aneurysms), or develop a split in the intima leading to an extending dissection - but "rupture"/"dissection" are merely classification of the type of aneurysm. ICD10 only lists for "Coronary artery aneurysm", there is no distinct "Coronary artery dissection", unlike cerebral codes which do differentiate:

I60.7 Subarachnoid haemorrhage from intracranial artery, unspecified Index
I67.0 Dissection of cerebral arteries, nonruptured. Excludes: ruptured cerebral arteries

Coronary artery aneurysm already discuss a range of causes of "atherosclerosis, Kawasaki disease and coronary catheterization", the second starts as just swellings, the third will be a dissecting aneurysm without prior dilatation, i.e. that article is already covering the different types of aneurysm (inactive swelling rupture and dissecting) although does not explain this very well (yet). Therefore with aneurysm being the umbrella term, Coronary artery dissection should be merged here as a major section of that article. David Ruben ^Talk 08:55, 4 November 2009 (UTC)[reply]

Oppose merger a dissection results in a pseudoaneurysm, which is quite distinct from an aneurysm, the former lacking an endothelial lining (intima). In addition, Coronary artery aneurysm doesn't appear to "discuss" anything as asserted above - it's little more than a stub. I've never edited either page. -- Scray (talk) 12:09, 4 November 2009 (UTC)[reply]

Oppose. The two diseases are distinct. Some aneurysms do indeed lead to dissection. However this is certainly not always the case. Not all dissections are preceded by aneurysms. This article ("Coronary artery aneurysm") requires clean-up, which would help to clarify this distinction. Axl ¤ [Talk] 18:57, 4 November 2009 (UTC)[reply]

Oppose - Both are individual diseases, irrespective of whether the dissection becomes more likely with an aneurysm. It's the same reason for which we have abdominal aortic aneurysm and aortic dissection. Regards, --—Cyclonenim | Chat 21:14, 5 November 2009 (UTC)[reply]

I have removed the merge notice on the article, as there appears to be no desire for a merger here after a month. Jhbuk (talk) 19:26, 29 November 2009 (UTC)[reply]
