1 Successful surgical resection of giant arteriovenous malformation in supraclavicular fossa 
Kohei Horikawa, MD, Hiroyuki Nishi, MD, Naosumi Sekiya, MD, Mitsutomo Yamada, MD, Toshiki Takahashi, MD  Journal of Vascular Surgery Cases and Innovative Techniques  Volume 4, Issue 2, Pages (June 2018) DOI: /j.jvscit Copyright © 2018 The Author(s) Terms and Conditions

2 Fig 1 Preoperative computed tomography (CT) findings. a, Findings obtained with three-dimensional CT revealed feeding arteries and drainage veins around the mass. b1, Clavicular branch of left internal mammary artery. b2, Transverse cervical artery feeding the arteriovenous malformation (AVM). b3, At least three drainage veins were shown (arrows). c, Preoperative magnetic resonance imaging and angiography findings. An AVM is seen compressing the brachial plexus (arrows). d, Four major feeding arteries were shown: 1, transverse cervical artery; 2, clavicular branch of left internal mammary artery; 3, thoracoacromial artery; and 4, anterior/posterior circumflex humeral artery.

3 Fig 2 Surgical procedures. a, The left clavicle was removed to expose the arteriovenous malformation (AVM; asterisk). The edge of the clavicle was visualized (arrow). b, Feeding arteries (asterisks) were detected and divided, marked with silicone tapes, and were then divided with ligation. c, An ultrasonic scalpel was used near the brachial plexus (asterisk). The AVM (▲) was retracted with forceps. d, Drainage veins (asterisks) were clamped. e, The AVM was completely excised.

4 Fig 3 Postoperative computed tomography (CT) findings. a, No mass enhancement was seen near the left subclavian artery (circle). b, Complete resection of the mass is shown (circles). The arrows note the titanium plate used to fix the clavicle.
