neck, the left superior thyroid vein and communicating vein were identified. The concomitant vein was anastomosed to the left superior thyroid vein and communicating vein. The muscle flap was transpositioned beneath the right grafted ribs to eliminate air leakage (Figure 8). A NPWT device was placed on artificial dermis that was applied to the rest of the defect. The flap survived with the successful elimination of air leakage from the right upper lung (Figure 9). An additional skin graft operation was planned on the 127th day.

4. Results

Ultimately, complete coverage of the chest wall was achieved on the 175th day. His respiration is now managed with a tracheostomy tube with spontaneous respiration (Figure 10). Nonverbal communication is possible. He was transferred to another hospital for further continuous rehabilitation. No complication have been confirmed for further follow-up.

5. Discussion

IMA injuries can occur after blunt trauma or be iatrogenic. They often accompany rib or sternum fracture. Continuous bleeding can lead to the development of mediastinal hematoma or hemothorax, which should be immediately controlled. Whereas IMA injuries have mainly been due to blunt trauma, a growing number of cases are caused by CPR, for which the recommended compression depth has been increased to 5 cm [2] . Kawakami et al. reported a case of IMA injury related to CPR with successful TAE [3] . Yamagishi et al. reported five cases of IMA injuries related to CPR with TAE followed by no complications [4] . TAE is a reliable treatment option for IMA injuries and some cases have been reported despite a controversy regarding whether to choose thoracotomy or conservative embolization [5] . Our patient underwent TAE of the bilateral IMAs, which was complicated by the formation of an ischemic skin change on the chest wall 17 days after TAE. To the best of our knowledge, this is the first reported case of extensive chest wall necrosis after TAE of IMA. Whigham et al. reported that 12 of 18 cases of hemorrhage from an intercostal artery were successfully treated with TAE without any complications [6] . Chemelli et al reported that there were no necrotic complications of the chest after TAE for intercostal artery injuries [7] . Corvino et al. also reported no major or minor complications after TAE of IMA [8] . Since there are no previous reports of chest wall necrosis, the incidence of this complication is unknown.

IMA is the third branch of the subclavian artery. It descends peripherally and bifurcates into the musculophrenic artery and superior epigastric artery. Extensive necrosis of the chest wall, flail chest or malfunction of the diaphragm can be considered a complication of TAE of IMA. When our patient was referred to our department, he had ischemic skin change with a clear margin, which was extensively debrided during the operation to prevent the outbreak and progression of sepsis. The defect after debridement included the heart, lungs, some ribs and diaphragm, and we applied an NPWT device to promote the formation of granulation to be covered with tissue. Reconstruction of the chest wall was challenging in several respects. There have been previous reports on chest wall reconstruction and various strategies [9] [10] . In terms of chest wall defects, treatment with the use of a vacuum-assisted closure device for sternal osteomyelitis for surgical site infection has been widely reported. However, there have been no reports in which an exposed heart was treated with NPWT, as in our patient. We placed non-adherent mesh between polyurethane foam and the heart to prevent adhesion. Since the chest wall protects the intrathoracic organs and respiratory function, extensive defects may lead to a loss of chest wall stability and paradoxical movement of the lungs. Reconstruction should be planned from a multidisciplinary point of view, and should involve both a thoracic surgeon and a plastic surgeon. Knowledge of the chest wall anatomy is essential. In this case, the goal of reconstructing the chest wall was to restore stability and integrity, protect the intrathoracic organs, repair the air leak from the lung and move him off the ventilator. We first needed to plan how to achieve skeletal stability after a significant loss of ribs. We chose bilateral latissimus dorsi myocutaneous flaps with ribs, which were fixed with sternum wire to recipient ribs. After achieving skeletal rigidity, coverage by soft tissue was necessary. We chose an anterolateral thigh flap to cover the chest wall and repair the air leak. Due to his medical history of calciphylaxis, significant calcification of blood vessels was found, which made blood distribution difficult and resulted in necrosis of the bilateral distal latissimus dorsi flaps. He also showed poor wound healing of the skin graft. We eventually were able to move him off the ventilator support with the elimination of air leakage, and his respiration is currently being controlled by only a tracheostomy tube. On the 233rd day, he was referred to another hospital for further rehabilitation.

There are several possible explanations for what triggered necrosis of the chest wall. Previous reports have examined what contributes to the formation of necrotic gluteal skin changes after TAE of internal iliac artery after hemorrhage caused by pelvic fracture. Yamamoto reported that skin and muscle necrosis after TAE can be attributed to the damage sustained at the time of the accident rather than to TAE itself [11] . Suzuki reported that skin and muscle necrosis are aggravated by the combination of decreased blood flow due to embolization and the ischemia of soft tissue caused by the injury [12] . Yoshino reported that advances in technology have contributed to the improved performance of TAE of IMA sparing its main trunk. He also stated that, regarding TAE of IMA, there has been little discussion of the importance of preserving its main trunk by selective arterial embolization through the use of advanced technologies, considering the possible complications caused by nonselective embolization, such as the overflow of the embolization material toward a vertebral artery or the outflow of chemo-drugs to the skin [13] . While there has been no statistical analysis of what causes chest wall necrosis after TAE of IMA, we think that, in our patient, the damage to the anterior chest wall caused by CPR and his medical history of calciphylaxis increased the risk of complications.

6. Conclusion

TAE is minimally invasive and therefore favorable for controlling mediastinal hemorrhage due to internal artery injuries. However, during the course of treatment, we need to consider the possible serious complications associated with obstructions of IMAs, such as chest wall necrosis. Since the 2010 American Heart Association Guidelines emphasize the need for CPR and recommend compression of more than 5 cm, the number of CPR-related IMA injuries may increase. Early diagnosis followed by immediate debridement needs to be performed to prevent infective complications. This is the first reported case of chest wall reconstruction after extensive chest wall necrosis caused by TAE of bilateral IMAs injured by CPR, which was successfully treated with multidisciplinary planning.
