In the medical literature, "multi-component parallel endografts at complex tevar may be prone to modular dislocation causing novel endoleaks: a tale of two cases" was reviewed.Two cases of complex thoracic endovascular aneurysm repair (tevar) with endoleakage due to modular dislocation of multi-component left subclavian parallel endografts in periscope configuration were reported.In this case, a (b)(6) female presented with a 75mm thoracic aortic aneurysm.She underwent a hybrid periscope-tevar procedure using two overlapped thoracic endoprostheses (alpha thoracic, cook aortic) and two 8mm x 10cm gore® viabahn® endoprostheses with propaten bioactive surface.The gore® viabahn® endoprostheses were synchronously deployed as a left subclavian artery periscope via an open brachial approach with an intentioned 2-cm overlap.After 48 hours, the patient was discharged with no complications and a palpable left radial pulse.It was stated that a computed tomography angiogram in the second week post procedure revealed modular dislocation between the two gore® viabahn® endoprostheses with endoleakage into the thoracic aortic aneurysm sac.A repeat computed tomography angiogram at 8 weeks post procedure revealed sac enlargement to 85mm with both components of the left subclavian artery periscope still patent.The patient underwent an urgent re-line of the left subclavian artery periscope.The two components of the periscope were bridged with an 8mm x 10cm gore® viabahn® endoprosthesis with propaten bioactive surface.The completion angiogram revealed no endoleaks and the patient was discharged home with a good left radial pulse, and no neurological complications.
