Introduction: Pseudo aneurysm of the ankle is a rare
presentation and the management is complex due to the
complex anatomy. The aim of this review is to examine the
epidemiology, etiology, diagnostic modalities used and
management. This is the first systematic review of this topic
in literature.
Methods: We performed a systematic review in multiple
databases (including PubMed, MEDLINE, EMBASE, and
Scopus) from 1966 to May 18, 2019, to identify all case
reports and case series describing patients with ankle
pseudo aneurysm. This systematic review was performed in
accordance with the Preferred Reporting Items for a
Systematic Review and Meta-analysis (PRISMA). Our
inclusion criteria included patients with ankle pseudo
aneurysm of any age. We excluded reports in which the
individual level data is not available. Patients demographic
(gender, age), clinical characteristics (precipitating event,
duration), diagnostic modality and treatment were recorded.
Result: There were in total 23 case reports identified on
ankle pseudo aneurysm from 1966 until 2018. Among these
twenty-three reports, 16 (70%) were male and seven (30%)
patients were female. Age distribution showed higher
number of reports among young adults, 15 patients (65%).
Based on our systematic review trauma (48%), arthroscope
(48%) and arthrodesis (4%) were the etiologies described in
all these case reports. Ultrasound duplex and CT Angiogram
has been used as a single modality in three reports each. In
fifteen patients (65%) combination of imaging has been used
for diagnosis. Anterior tibial artery is the most commonly
injured vessel among the reported cases, comprised of 14
(61%) patients. Among these arthroscopes were the highest
reported precipitating events, 9 (64%), followed by trauma in
four patients (29%) and arthrodesis in one patient (7%).
Treatment modalities described in all previous reports were
excision and ligation, 10 (42%); excision of sac and primary
repair, 4 (17%); excision of sac followed by reversed
saphenous venous graft repair, 2 (8%); US guided
compression, 2 (8%); US guided thrombin injection, 4 (17%);
stenting, 1 (4%) and coiling, 1 (4%).
Conclusion: Ankle pseudoaneurysm is mostly preventable
by detailed initial assessment following trauma or careful
approach during arthroscope. Evolving diagnostic modality
and treatment has shed some light into noninvasive
management of pseudo aneurysm of ankle.
