This is a review article describing some new and interesting aspects in the diagnosis and treatment in systemic vasculitis and demonstrating several cases that we have encountered. Particular emphasis will be put on Takayasu arteritis (also known as aortitis syndrome) most commonly observed in Japan and other oriental countries. CT and MRI better demonstrate the vessel wall abnormality of Takayasu arteritis than angiography. Importance of plain chest radiograph should also be kept in mind; it could provide a clue in the diagnosis of Takayasu arteritis in its early stage.

A 13-month-old girl (BW 4476g) with Taussig-Bing malformation was successfully treated by anterior intraventricular tunnel repair (Patrick-McGoon method). She had large subpulmonary malalignment ventricular septal defect with extreme inflow extension with anteroposterior relationship of the great arteries. Coronary arterial anatomy was a very rare type in that LAD branching from RCA originated from right facing sinus was running just anterior to the aorta and coronary relocation would result in straining and obstructing LAD. Intraventricular tunnel through the VSD to the aorta was tailored by use of a double velour Dacron conduit (14mm in diameter) and inflow extension of VSD was partly closed with a separate flat Dacron patch. LVOTO was not found on echocardiography and good clinical results were obtained at 11 months postoperatively.

In part 1 of this article, clinical features and imaging findings of Takayasu arteritis (also known as aortitis syndrome) were described in detail. In part 2, treatment of Takayasu arteritis will be first described and discussed. This will be followed by description of clinical features and imaging findings of other systemic vasculitis. Comments on interventional radiology for systemic vasculitis will also be made.

[Purpose]The purpose of this paper is to examine whether or not the Press Tack Needle (PTN) treatment enhances the recovery process from muscle fatigue which assists in the therapeutic exercise rehabilitation process. By using the PTN, this paper investigates the recovery effect of the fatigued muscle. Randomized controlled trials were used to compare outcomes.
[Method]Twenty-nine healthy male adults were chosen as subjects. However, crossover study was used to compare the PTN group and the sham group. After two sets of arm curl exercises with isotonic contraction at 10%weight of maximum voluntary contraction, the decrease percentage of exercise repetition was calculated. A PTN or sham was inserted at the posterior cervical region using the double masking method. After the intervention of the PTN or sham needle, the subjects were asked which intervention was inserted into them. A Kappa statistics value was used to evaluate the validity of the sham group and a Visual Analog Scale (VAS) was used to determine the upper arm fatigue.
[Result]The Kappa statistic value was 0.17. The decrease percentage of the exercise repetition of the PTN group was 35.4±20.1%, and of the sham group was 45.1±11.1%. The PTN group indicated a significantly smaller percentage than the sham group (p<0.01). Both groups showed no difference in Upper arm fatigue.
[Conclusion]The PTN seems to help in recovery from muscle fatigue. It is thought that by inserting the PTN, somato-automomic reflex was induced to promote the increase of blood flow in to the muscle. Faster recovery of physical function of the patient can be possible as well as the improvement of QOL. In conclusion, this investigation showed that the PTN treatment method can be useful in assisting in therapeutic exercise rehabilitation.

A 26-year-old man with Marfan's syndrome suffered aortic dissection repeatedly during hospitalization. He was admitted with a diagnosis of annuloaortic ectasia with severe aortic regurgitation. A type A aortic dissection occurred after diagnostic angiography. Three weeks after the onset of the dissection, an aortic root replacement in combination with a total arch replacement was performed. Eight months later, residual dissection in the descending thoracic aorta was replaced with distal perfusion by a temporary bypass from the left subclavian artery to the descending thoracic aorta. At the termination of the operation, abdominal aortic dissection occurred with acute bilateral limb ischemia, which was treated with abdominal aortic intimal fenestration. He recovered uneventfully and was discharged 3 weeks after operation. In light of our experience, because of vascular fragility, great care should be taken in treating patients with Marfan's syndrome to avoid iatrogenic aortic dissection.

Treating a thoracic aortic aneurysm (TAA) after coronary artery bypass graft (CABG) surgery requires an appropriate surgical procedure to preserve the functional graft. We present a case of hybrid procedure of thoracic endovascular aortic repair combined with a redo off-pump CABG via median sternotomy. The patient was a 76-year-old man with a history of CABG and abdominal aortic replacement in a different country. Chest computed tomography revealed a saccular-shaped aortic aneurysm in the distal aortic arch with diameter of 5.6 cm. Coronary angiography revealed theLIMA graft was patent but anastomosed to the diagonal branch and the left anterior descending artery (LAD) was totally occluded and was opacified through the right coronary artery. Significant ischemic change in the anteroseptal wall suggested a requirement of surgical revascularization of LAD. The chest was opened via re-midsternotomy. Then the 3 arch vessels were reconstructed with a trifurcated artificial graft attached to the ascending aorta and coronary artery bypass grafting was performed on the beating heart. Finally, the aneurysm was excluded by introducing a stent graft through the graft to zone 0. The patient's postoperative course was uneventful and he was discharged on postoperative day 16. A hybrid procedure via median sternotomy was useful in the surgery for TAA with the functional LIMA after CABG.

Objectives: Traumatic optic neuropathy (TON), a relatively rare condition, can cause visual functional impairment and permanent functional damage.Surgeons should be familiar with its diagnostic criteria and treatment to effectively manage cases of facial trauma with TON. We investigated the feasibility of navigation-assisted endoscopic trans-nasal optic nerve decompression (ETOND) to treat TON in maxillofacial trauma patients. Patients and Methods: We retrospectively analyzed data from the clinical investigation of four consecutive patients, two males and two females with an average age of 75 years, with midfacial fractures and TON between April 2021 and September 2023. All patients had swelling and subcutaneous periorbital hemorrhage accompanied by optic nerve canal and zygomaticomaxillary complex fractures on the affected side. Three patients had lacerations on the lateral eyebrow or upper eyelid. All patients were evaluated by an ophthalmologist for visual impairment; two patients could see hand motion at a 30 cm distance, one patient could perceive light, and one did not have any loss of visual acuity. Among the four patients, three had visual impairment immediately after the injury, and one showed delayed impairment. Results: The patients were treated with navigation-assisted ETOND conducted by an endoscopic rhinologist. Three of the ETONDs were performed along with open reduction and internal fixation (ORIF); the other ETOND was delayed. Orbital reconstruction was performed in three patients. Steroid therapy was administered to two patients, one pre-operatively and one post-operatively. The two patients with pre-operative vision loss showed improved visual acuity post-operatively, and the two patients with no pre-operative visual impairment had no vision loss associated with ORIF for their midfacial fractures. No patient had post-operative complications. Conclusion Navigation-assisted ETOND can be performed easily by endoscopic rhinologists; and prompt examination, diagnosis, and treatment are important in patients with facial trauma and TON.

Most mediastinal abscesses result from infections after thoracotomy, esophageal perforation or pene- trating chest trauma. This disease is rarely caused by closed blunt chest trauma. All previously reported such cases after closed blunt chest trauma presented with hematoma and sternal osteomyelitis resulting from sternal fracture. Here we report a 15-year-old sumo wrestler who presented with an anterior mediastinal abscess without any mediastinal fracture. The mediastinal abscess resulted from the hematogenous spread of Staphylococcus aureus to a hematoma that might have been caused by a closed blunt chest trauma incurred during sumo wrestling exercises.
