“…[1][2][3][4][5][6][7][8][9][10] Resection, occlusion, or stenosis of the bilateral internal jugular veins is likely to induce serious complications such as elevated intracranial pressure, facial oedema, visual impairment, and the syndrome of inappropriate antidiuretic hormone secretion (SIADH), and can lead to death. [11][12][13][14] Internal jugular vein thrombosis associated with pulmonary embolism is also a frequent complication 15 and may lead to anastomotic thrombosis in free flap reconstruction. [16][17][18] Risk factors for internal jugular vein occlusion and stenosis include technical problems associated with vessel dissection, such as the method of branch ligation, thermal injury to the vein caused by electrocautery, and dryness after outer membrane detachment, 1,8 and aspects of the reconstructive procedure, including pressure in internal jugular veins in the musculocutaneous flap.…”
