title: Primary repair of internal carotid artery aneurysm secondary to kinking and cystic medial degeneration.
abstract: BACKGROUND
  In this report, we aim to present a very rare case of internal carotid artery (ICA) aneurysm secondary to kinking and cystic medial degeneration.
  
  
  METHODS
  A 66-year-old female patient was admitted to our institution for multidetector computed tomography (MDCT) angiography of supra-aortic trunks. On admission, she complained of occasional dizziness; 2 months earlier ascending aorta reconstruction was done for aneurysmal disease. Color Doppler ultrasonography and MDCT arteriography revealed significant right ICA kinking associated with large aneurysm, 24.6 × 24.5 mm(2) in diameter. Aneurysm resection was done followed by ICA reconstruction by end-to-end anastomosis. Pathohistological findings of aneurysmal sac revealed cystical medial degeneration with inflammatory infiltrate mostly consisting of lymphocytes and fibrovascular proliferation.
  
  
  CONCLUSIONS
  This is the first case that describes mutual contribution of cystic medial degeneration and ICA kinking in carotid aneurysm disease etiology successfully treated by aneurysm resection.
