Pseudoaneurysms of thoracic aorta represent
life-threatening complications of cardiac surgery.
We present a case report of a patient who underwent
urgent aortic valvular replacement with a biological
prosthesis and ascending aortic replacement with graft
interposition and developed postoperative ascending
aortic pseudoaneurysms. The pseudoaneurysms did not
increase in the postoperative stay and a conservative
management was chosen. At follow-up, the two
pseudoaneurysms had completely regressed.
The therapeutic steps for aortic pseudoaneurysms
should be tailored to the patient and even
conservative management could be effective if
selected after an evaluation of the clinical status of the
patient.

A 62-year-old woman was admitted to our department for
acute aortic type A dissection and severe aortic valvular
regurgitation. Associated diseases were restrictive chronic
obstructive pulmonary disease (COPD), chronic renal
insufficiency and uncontrolled hypertension. The patient
underwent urgent aortic valve replacement with bio-
logical prosthesis and ascending aortic replacement with
graft interposition.
The postoperative course was characterized by pyrexia,
leukocytosis and increased C-reactive protein with
negative blood and urine cultures and without sternal
wound involvement. Multislice computed tomography
(MSCT) showed two aortic pseudoaneurysms at the level
of the distal anastomosis of the vascular graft, close to the
aortic root (Fig. 1a).
An empirical antimicrobial therapy with intravenous
broad-spectrum antibiotics was initiated, and the inflam-
matory indexes rapidly normalized. The antimicrobial
therapy was discontinued after 20 days. The patient
was asymptomatic and a MSCT scan did not reveal a
progression of the pseudoaneurysms. In consideration of
the clinical and instrumental parameters, we opted for
conservative management and a MSTC scan follow-up
was planned. The patient was discharged on postopera-
tive day 30.
At 3-month follow-up, the MSCT showed the regression of
the smaller pseudoaneurysm and a slight increase of the
second one (Fig. 1b). The patient reported no symptoms
and pyrexia and blood samples were normal. The general
clinical status led to delay of surgery and to strictly control
blood pressure. At 6-month follow-up, even the second
pseudoaneurysm had completely regressed (Fig. 1c).
Postoperative pseudoaneurysms of the ascending aorta
are uncommon complications of cardiac surgery, occur-
ring in fewer than 5% of all cardiac operations.

They
can be located at every surgical site and their risk
factors include infections, intrinsic aortic wall disease,
poor anastomotic technique and tissue necrosis due to
abusive use of gelatin–resorcin–formol glue.
Surgical treatment is considered the gold standard therapy
and includes several different approaches.

However,
although safe techniques were developed in the past de-
cade, hospital mortality may reach 17–20%

be considered when the timing of the surgery is planned.
The conservative management of pseudoaneurysms of
the ascending thoracic aorta is often avoided, especially if
