title: [EFFECTIVENESS OF SURGICAL TREATMENT OF SYMPTOMATIC TORTUOSITY COMMON CAROTID ARTERY].
abstract: OBJECTIVE
  To investigate the safety and effectiveness of vascular reconstruction in patients with symptomatic tortuosity common carotid artery (SCAT).
  
  
  METHODS
  A retrospective analysis was made on the clinical data of 12 cases of SCAT treated with vascular reconstruction between June 2010 and October 2013. There were 11 females and 1 male with the mean age of 54.8 years (range, 48-62 years). The unilateral common carotid artery was involved in all cases. Imaging examination showed C-shaped tortuosity of 4-8 cm in length (mean, 5.4 cm). The CT, brain CT, ultrasound examinations, or angiography was performed at 1, 3, 6, 9, and 12 months, and annually.
  
  
  RESULTS
  The surgery success rate was 100% with no perioperative death and serious complications. The mean operation time was 1.98 hours; the mean blood loss was 50 mL; and the mean clamping time was 14.9 minutes. The systolic pressure gradient across the lesion was significantly decreased from (39.58 ± 9.54) mm Hg (1 mm Hg = 0.133 kPa) at pre-operation to (5.50 ± 2.39) mm Hg at immediate after operation (t = 15.492, P = 0.000). No recurrence or stenosis was found at 9 months to 3 years of follow-up. The systolic and diastolic pressures at last follow-up were significantly improved to (132.17 ± 6.24) mm Hg and (82.67 ± 6.51) mm Hg from (152.83 ± 14.80) mm Hg and (94.17 ± 11.30) mm Hg at pre-operation (t = 5.751, P = 0.000; t = 4.976, P = 0.000).
  
  
  CONCLUSIONS
  Vascular reconstruction in SCAT is recommended for good short- and mid-term effectiveness and relatively low complication and mortality after operation. Moreover, the long-term results still need to be investigated.
