Femoral Aneurysm In A Dog
by mandercrosby - November 8, 2020    View Case Report
Hi there,

Francis is a 15.5yo MN Coton de Tulear who presented 1 week ago for acute onset swelling of his LH limb along with fever and inappetence. He has a history of IVDD, which had flared up recently, but seemed to improve with acupuncture and gabapentin. He also has a history of chronic intermittent GI upset (vomiting, inappetence, and diarrhea) that has recently worsened. He also has a history of frequent dermatitis that may be related to food allergies.

He was admitted to the ER and a left femoral artery aneurysm was identified, though the underlying cause is unknown. Rads and AUS were unremarkable aside from mild hepatomegaly. He has mildly elevated liver values, borderline anemia, and all else was normal. He began to have severe bruising from the perineum to toes on the LH. He was sent home with yunnan bayao and aminocaproic acid. He was unable to urinate on his own or stand, at time of discharge, but has since regained the ability to do both. He has had gabapentin for pain control as codeine seemed to cause too much lethargy.

Unfortunately after discharge he continued to be inappetent, so Entyce was started and he had another acupuncture session, which seemed to help his attitude. He has been drinking very well, but is still quite lethargic and has not defecated in 3 days. The stool was soft at his last BM.

On exam today the swelling and bruising LH is profoundly improved, though he remains minimal weight bearing lame and prefers not to walk much. His spine was non painful on palpation, abdomen soft and non painful, MMs pale pk and mst, with CRT <2s. His heart and lungs are normal, and he was QAR but brighter after treatment.

His TCVM exam revealed a pink, slightly dry tongue and rapid wiry pulses. He had heat over GV 14 and depressions at BL 20 and 23. Feet were normal (LH was warm), ear tips were normal. The owner reports he is always cold.

I treated him with An Shen, GV 14, Bai Hui, BL 18/20/23, ST 36, SP 10, and PC 6. He was eating treats, drinking, and will to stand briefly during treatment. His pulses were less forceful after.

I'd say he has spleen qi deficiency (and global qi deficiency), blood deficiency, liver blood deficiency/qi stagnation, and blood stasis along with a history of blood heat.

I started him on cerenia, tramadol, and switched from entyce to mirtazapine, but am curious about what herbal options might be possible. He didn't have a fever today, but I am concerned there may be some cyclical fever going on. Any advice would be appreciated! Thank you!

Hi there,

A challenging case! I hope you'll keep us posted on it!

I guess my first thought is whether his drug doses are sufficient to depress his appetite and make him sluggish. Is he still on them? Can prn dosing be explored?

That being said, the rapid forceful pulse in the absence of any Heat signs suggests stress, which may be due to an unappreciated locus of pain. From a Chinese medical point of view, it often suggests Stasis, especially in the Shao Yang

Shao Yang disharmony is consistent with much of the rest of the case, including pain, fever, allergies, stress, and GI upset. It is almost always there when we have a risk of sudden death (such as from a bleed out from aneurysms in general). It is the primary cause of generalized tendency to Blood stasis, which this dog definitely has with his bruising. It leads to Source Qi deficiency, with its attendant weakness and inappetance. It tends to happen in the fall (and spring).

So, given the above, I'd look at Xiao Chai Hu Tang as an ideal treatment overall. For the bruising and leg pain, consider Shen Tong Zhu Yu Tang or (given the coldness and weakness) Xiao Huo Luo Dan. The latter is probably the best choice of the two. It can be used with the XCHT and the YBY.

Regardless of the apparent inciting cause, aneurysms develop because of chronic inflammation within the vessel wall, so an inflammation resolving approach using formulas like the ones listed above should help from a biomedical perspective, too.

That's where I would start. Look for Shao Yang (i.e. GB) points being active and improving the pulse. If you find them, it helps confirm the assessment.

Hope that helps!

Thank you Steve! He is now off tramadol and sadly cerenia and mirtazapine have not helped, so we’ll discontinue both. The limb continues to improve, but his appetite has been terrible and I fear we’re now in a decision making stage. I think Shao Yang Disharmony fits and will start XCHT. Do you think the XCHT would help appetite rapidly? Or should I consider adding one of the gentlemen to help that? Thanks so much!

Maybe try adding the Six Gentlemen as well. Remember that nothing should die without trying corticosteroids. Dex can work wonders as a stimluant and anti-inflammatory. Just ask Donald Trump!
