Head and Neck Reconstruction of the Vessel-Depleted Neck: A Systematic Review of the Literature
Annals of Surgical Oncology, 2021Co-Authors: Beatriz Hatsue Kushida-contreras, Oscar J. Manrique, Miguel Angel Gaxiola-garcíaAbstract:Background Damage of the vascular system secondary to radical neck dissection and/or radiotherapy or other treatments has a negative impact on microsurgical reconstruction. The search for adequate recipient vessels is hindered by the complexity of previous procedures. Methods A systematic review of microsurgical head and neck reconstruction in the vessel-depleted neck was performed. The issues analyzed were indications for surgery, more frequently performed flaps, vascular systems used as recipient vessels, outcomes, and complications. Results The eligibility criteria were fulfilled by 57 studies published between September 1993 and January 2020. In 8235 patients, 8694 flaps were performed, 925 of which were for a vessel-depleted neck. The most commonly used flap was the anterolateral thigh flap, used in 195 cases (30%), followed by the radial forearm free flap, used in 157 cases (24%). The potential recipient vessels were numerous for arteries (26 options) and Veins (31 options). For the 712 flaps with an identifiable recipient artery, the Superficial Temporal artery was the most commonly used vessel ( n = 142, 20%). The Superficial Temporal Vein was the most commonly used vessel for 639 flaps with an identifiable recipient Vein ( n = 118, 18.5%). Complications amounted to 11%; 80 out of 716 flaps in papers that reported them. Flap losses were reported in 2% of cases. Conclusions Major microsurgical head and neck reconstruction for postoncologic defects depends on appropriate recipient vessels. Vein availability is paramount. Understanding the complexity of this problem is useful for preoperative planning, precise decision-making, and an accurate surgical approach.

Effect of computed tomographic venography on donor selection in submandibular gland transplantation in patients with severe dry eye
JOURNAL OF CRANIO-MAXILLOFACIAL SURGERY, 2017Co-Authors: Su Jia-zeng, Yu Hong-kui, Sun Zhi-peng, Liu Xiao-jing, Cai Zhi-gang, Lv Lan, Yu Guang-yanAbstract:Background: A reliable anterior facial Vein (AFV, donor Vein) is cardinal for the success of submandibular gland (SMG) transplantation. This study determined the impact of computed tomographic (CT) venography in identifying AFV variations for SMG transplantation. Methods: CT venography was performed in consecutive patients with severe dry eye prior to SMG transplantation in order to identify disadvantageous AFV variations for vascular anastomosis, namely, AFVs that did not drain the SMG and those that did not match the Superficial Temporal Vein (STV, recipient Vein; AFV: STV caliber ratio, >= 3). The CT results were compared with the intraoperative findings for the diagnostic accuracy. Results: Forty-two donors were included. Compared with the intraoperative findings, the CT results accurately identified AFV-STV caliber mismatches (P = 1.00; sensitivity and specificity, 100%). In the identification of AFVs not draining the SMG, CT showed 94.7% sensitivity and 100% specificity (P = 0.25). According to the CT findings, 10 contralateral SMGs with AFVs (23.8%), instead of ipsilateral donors, were selected for transplantations (conventionally ipsilateral donor was the first choice). The surgical success rate was 95.2% (40/42). Conclusion: CT venography is valuable in determining disadvantageous AFV variations for anastomosis and choosing a reliable donor for SMG transplantation.

Vascular consideration in repair of total scalp avulsion.
BMJ case reports, 2017Co-Authors: Jun Karibe, Toshiharu MinabeAbstract:Successful total scalp replantation was performed in our case. Based on the angiosome concept and anatomical study, the avulsed scalp survived with unilateral anastomosis of the Superficial Temporal artery and Superficial Temporal Vein, largely due to the presence of rich arterial and venous arcades in the scalp. The patient currently has no problems with activities of daily living, although total hypoaesthesia and dysfunction of the left frontal muscle of the forehead are present. In addition, the combined findings of hair growth pattern indicated the vascular territories of the scalp skin.

Venous drainage architecture of the Temporal and parietal regions: anatomy of the Superficial Temporal artery and Vein.
Plastic and reconstructive surgery, 2002Co-Authors: Nobuaki Imanishi, Hideo Nakajima, Toshiharu Minabe, Hak Chang, Sadakazu AisoAbstract:Anatomy of the Superficial Temporal artery and Vein was analyzed with arteriograms, venograms, and arteriovenograms of fresh cadavers that had been injected with contrast medium. The Superficial Temporal artery always divided into two major branches: the frontal and parietal branches. However, the Superficial Temporal Vein divided into one, two, or three major branches. The distribution area of the major branches of the Superficial Temporal Vein was larger than that of major branches of the Superficial Temporal artery, and arteriovenograms clearly demonstrated that, except for its proximal portion, the Superficial Temporal Vein was independent of the Superficial Temporal artery. The frontal and parietal branches of the Superficial Temporal artery had thin venae comitantes that originated from the proximal portion of the Superficial Temporal Vein, and the venae comitantes gave off branches toward the skin and the underlying soft tissue. Branches to the skin anastomosed with a Superficial venous network in the skin layer, which was formed by ramifications of the Superficial Temporal Vein. The venous architecture of the Temporal and parietal regions consisted of cutaneous Veins and venae comitantes and was basically similar to that of the forearm and scapular region.
