A 69-year-old woman, who had undergone a right nephrectomy for renal tuberculosis in her teens, was admitted with a low grade fever, anorexia and progressive dyspnea. Transthoracic echocardiography showed cardiac tamponade and chest CT revealed an enlarged ascending aorta. She was treated with pericardiocentesis. Specimens of pericardial effusion failed to demonstrate any acid-fast bacilli, but they did reveal a high level of adnosine deaminase (72 IU/l). A diagnosis of tuberculous pericarditis was considered, and antituberculous chemotherapy was started. However, he presented with severe back pain 32 days later and CT revealed type A acute aortic dissection. We therefore replaced the ascending aorta and aortic root. A histopathological examination of the ascending aorta revealed evidence of a granulomatous inflammatory reaction with Langhans giant cells. She thereafter received antituberculous chemotherapy with 4 drugs for 2 months, with continued rifampicin and isoniazid treatment. There was no evidence of any graft infection after 70 days.

We report the case of a 55-year-old woman with aortitis syndrome. She was admitted to our hospital because of repeated chest pain and syncope. An electrocardiogram and the laboratory data suggested acute myocardial infarction, and coronary angiography showed severe bilateral coronary ostial stenosis. No valvular disease was observed. Aortitis syndrome was suspected because of the stenosis of the brachiocephalic artery in addition to the bilateral coronary ostial stenosis, while the patient did not have elevated C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Coronary artery bypass grafting was performed, and the patient's postoperative course was uneventful. However, she again experienced chest pain 9 months after surgery due to aortic regurgitation (AR) and diffuse narrowing change of the left internal thoracic artery graft. Aortic valve replacement and Re-CABG was performed, and the patient was treated with steroid therapy postoperatively. The postoperative course was uneventful, but the patient thereafter died due to bleeding of a malignant adrenal tumor at 21 months after the second surgery.

A sinus of Valsalva aneurysm is a rare cardiac disorder, and reports of it with an anomalous origin of the coronary artery are scarce. A 35-year-old male was admitted to our department with fatigue and cough. Multi-detector-row computer tomography (MDCT) revealed an isolated extracardiac right sinus of Valsalva aneurysm with an anomalous origin of the left circumflex artery (LCX) and total occlusion of the right coronary artery (RCA). Its diameter was about 70 mm. We performed a partial aortic root remodeling procedure with a trimmed J-graft because he had neither aortic regurgitation (AR) nor annuloaortic ectasia (AAE). Concomitantly, coronary artery bypass grafting to the RCA (Seg. 3) using a saphenous vein, and reconstruction of the LCX by Piehler's technique using a saphenous vein were added. The patient's postoperative course was uneventful, and he was discharged on the 28th postoperative day. Postoperative MDCT revealed that the aneurysm of the right sinus of Valsalva was not enhanced, and the RCA and LCX were patent. This procedure preserved the patient's own normal aortic valve and sinus of Valsalva and enables him to have more physiologically normal hemodynamics than aortic root reconstruction using a composite graft, e.g. Bentall procedure, Cabrol procedure, although the potential progression of the AR requires careful follow-up.

Methods: Cases of 50 patients with ASD who underwent long spinal fusion (>9 levels) with S2AI screws were retrospectively reviewed. Loosening of S2AI screws and S1 pedicle screws and bone fusion at the level of L5–S1 at 2 years after surgery were investigated using computed tomography. In addition, risk factors for loosening of S2AI screws were determined in patients with ASD. Results: At 2 years after surgery, 33 cases (66%) of S2AI screw loosening and six cases (12%) of S1 pedicle screw loosening were observed. In 40 of 47 cases (85%), bone fusion at L5–S1 was found. Pseudarthrosis at L5–S1 was not significantly associated with S2AI screw loosening (19.3% vs. 6.3%, p=0.23), but significantly higher in patients with S1 screw loosening (83.3% vs. 4.9%, p<0.001). On multivariate logistic regression analyses, high upper instrumented vertebra (UIV) level (T5 or above) (odds ratio [OR], 4.4; 95% confidence interval [CI], 1.0–18.6; p=0.045) and obesity (OR, 11.4; 95% CI, 1.2–107.2; p=0.033) were independent risk factors for S2AI screw loosening. Conclusions High UIV level (T5 or above) and obesity were independent risk factors for S2AI screw loosening in patients with lumbosacral fixation in surgery for ASD. The incidence of lumbosacral fusion is associated with S1 screw loosening, but not S2AI screw loosening.
