Abstract
Introduction: To evaluate treatment outcomes
of patients diagnosed with Takayasu arteritis (TA), who underwent
extra-anatomical bypass surgery using biosynthetic grafts.
Methods:
This retrospective study included 12 TA patients considered eligible
for surgical revascularization between January 2005 and May 2011 from
two vascular surgical units in Turkey.Control group consisted of 12
peripheral arterial disease patients who underwent supra-aortic
extra-anatomical bypass surgery using polytetrafluoroethylene (PTFE)
graft. Preoperatively, all patients underwent Doppler ultrasound and
arteriography. Patients were examined every 3 months for clinical
findings after monthly follow-up during the first 6 months, first,
second and third year controls. Graft patencies were evaluated by
Doppler ultrasound at each visit.
Results: The mean age was 38.6 ± 4.2
years and the mean follow-up time was 37.9 ± 6.9 months for the study
group. In Biosynthetic Group, subclavian-subclavian (n = 2),
axillo-axillary (n = =9) and carotico-subclavian (n = 1) bypass
operations were performed. In PTFE group, subclavian-subclavian (n = 3),
axillo-axillary (n = 7), subclavian-left ulnar (n = 1),
subclavian-distal brachial (n = 1) bypass operations were performed.
Graft occlusion occurred in four patients in PTFE Group during follow-up
period. These occlusive lesions were treated successfully according to
the routine of each vascular unit.
Conclusion: We concluded that in
inflammatory diseases like TA, biosynthetic grafts havepromising
patency, postoperative clinical findings and lower rates of
complications requiringreintervention in mid-term.
