Recently, a huge neck hemangioma was successfully removed by the vascular surgery department of our hospital. The patient was diagnosed as a cavernous hemangioma 11 years ago when he found a soft mass on his right neck, but did not pay attention to it because there was no obvious discomfort. Over the years, the mass gradually increased in size, and the patient was refused treatment at several general hospitals or specialized hospitals. In late March, the patient was transferred to our vascular surgery department. The mass occupied the carotid artery sheath and the posterior aspect of the neck, and was adjacent to the posterior edge of the submandibular gland in the forward direction and extended to the posterior aspect of the right cephalobuccal muscle in the backward direction, pushing the right common jugular artery inward and adjacent to the jugular vein, and the mass reached subcutaneously outward. The right sternocleidomastoid muscle was invaded and the superficial cervical vein was penetrated within the swelling. On admission, a 13 cm × 9 cm swelling was palpable on the right side of the neck, with a slightly high skin temperature, soft to touch, no pressure pain, and elasticity, which could be reduced after squeezing and filled rapidly after pressure was removed. It reached the anterior border of the right sternocleidomastoid muscle anteriorly, the trapezius muscle posteriorly, the angle of the mandible upward, and the right clavicle inferiorly, with indistinct boundaries, no arterial pulsation was palpated, and no murmur was heard in the carotid artery. Admission diagnosis: right cervical hemangioma. After the patient was admitted to the hospital, several departments were consulted to assess the surgical risks, and the patient and his family were given a detailed explanation of his condition and surgical plan. The patient was carefully separated to protect the blood vessels and nerves in the neck as much as possible. The patient was transferred to the surgical ward after the operation, and was disconnected on the same day and transferred to the general ward the next day. The patient recovered well after surgery without any complications of nerve injury and no obstruction to neck movement, and is now stitched and ready for discharge. Spongiform hemangioma is a congenital vascular malformation, which is benign in nature but has the characteristic of growing and encroaching on adjacent normal tissues, and is difficult to stop bleeding during surgical excision because its main part is composed of a large number of thin-walled blood sinuses in a honeycomb pattern. In this case, the patient had visited several general tertiary hospitals and oncology hospitals, and was told that the surgery was inoperable. After receiving the patient, we performed detailed and thorough preoperative preparation and developed a plan to perform the surgery in a transcontouring fashion. With the assistance of the operating room, surgical supervision, bone tumor and other departments, this case of huge neck hemangioma was successfully removed by Dr. Zhang Xuemin without any neurovascular complications, which fully demonstrated the technical advantages of vascular surgery and the strong comprehensive strength of our multi-departmental collaboration.
