limited to older adults and does not account for younger
patients with migraine. Furthermore, Whedon et al. does not
address the potential interaction between migraine-related
vascular changes and mechanical stress from CSM.
Albertson et al. minimize the clinical presentation, stat-
ing that, “Outside of the description that the migraine lasted
for a few more days compared to the patient’s ten-year his-
tory of migraines, there was nothing unusual reported about
the patient’s symptoms prior to or after SMT to suggest
sinister pathology.” This is not the case. The patient sought
treatment for her usual Migraine symptoms, which typically
lasted 24 h and were responsive to NSAIDs. Immediately
after SMT, she experienced right-sided head pain lasting
over 10 days, unresponsive to NSAIDs, indicating a new
etiology. Albertson et al. hypothesize that the VAD predated
SMT, with symptoms mistaken for a migraine. However,
the abrupt shift to persistent, unresponsive symptoms post-
SMT suggests VAD occurred after manipulation, not before.
Albertson et al. opine that the absence of ischemic symp-
toms after SMT in this case is evidence that SMT had no
temporal relationship with the onset of symptoms. This is
difficult to understand. Cerebral ischemic symptoms are, by
definition, symptoms of ischemic stroke. This patient did
not suffer an ischemic stroke; she suffered a VAD. They also
observe that no VAD was found on CT brain imaging when
the patient presented to the emergency room after three days
of persistent headache following SMT. However, no CTA
or MRA neck imaging to evaluate for VAD was performed.
Albertson et al. cite Gorrell et al. [8] to claim SMT does
not stretch vertebral arteries enough to cause dissection.
This is true for arteries not at risk for dissection but not rel-
evant here, as Gorrell et al. did not assess migraineurs. Reli-
ance on such cadaver studies is limited in this context, as
cadaveric models may not account for in-vivo vulnerabili-
ties associated with migraine. They further cite Kocabey et
al. to support that SMT does not significantly alter blood
flow in the vertebral arteries [9]. This is again true, but not
Dear Editor-in-Chief,
I read the Romozzi et al. [1] case report and the Letter to
the Editor in response from Albertson, et al. [2] Romozzi
et al. proposed a plausible argument for causation of verte-
bral artery dissection (VAD) in a case of spinal manipulative
therapy (SMT). Albertson et al. ignored the plausibility of
the argument and instead criticized the article for reasons
unrelated to the hypothesis of Romozzi et al.
Albertson et al. opine that the terms VAD and cervi-
cal artery dissection (CAD) were used incorrectly. VAD is
subset of CAD, which also includes internal carotid artery
dissection (ICAD). Review of the case report reveals these
terms were used appropriately. CAD was used in the context
of the Biller et al. study, which studied cervical artery dis-
sections, per the title of the study [3]. They also state that
the V2 segment of the vertebral artery is not likely to dis-
sect from SMT. This would be the case in an artery not at
risk for dissection. They are ignoring the hypothesis of the
case report, which is that the artery was at risk for dissection
in this 25-year-old female patient with a 10-year history of
migraine without aura [4].
Albertson et al. opine that statements that SMT has a
known causal relationship with VAD are unsubstantiated.
However, Romozzi et al. make no such statements. Romozzi
et al. cite the Mikkelsen et al. case report to support that
SMT has a known association with VAD [5].
Albertson et al. cite Church et al. which concludes there
is no convincing evidence of a causal relationship between
SMT and CAD. However, this study does not stratify for
predisposing conditions like migraine [6]. They also cite
Whedon et al., which found no significant association
between chiropractic Manipulation and stroke in Medicare
beneficiaries aged 66–99 years [7]. However, this study is
