Metal Allergy in Cardiovascular Surgery : a Case Report / 日本心臓血管外科学会雑誌

We present a successful case of a patient with multiple metal allergy—cobalt, nickel, chromium, and zinc—who had a past history of systemic metal dermatitis. He was a 58-year-old man who complained of exertional chest discomfort. After admission, he had a fever and his blood culture was positive with methicillin-sensitive Staphylococcus aureus. Three days later, multiple micro cerebral infraction was detected in magnetic resonance imaging. After an improvement of inflammatory reaction, he was transferred to our facility for cardiac examination. Moderate mitral regurgitation due to valve perforation and multiple coronary vessel stenosis were detected. Mitral valve replacement and coronary artery bypass grafting were planned to perform. We chose surgical materials based on a preoperative epicutaneous (patch) test and his clinical course was uneventful without any allergic reaction. Metal contact allergy is an important issue in cardiovascular surgery. A collaboration with dermatologists is essential for the preparation of surgical materials.

A Case of Surgical Ventricular Restoration with Heparin-Induced Thrombocytopenia Type II / 日本心臓血管外科学会雑誌

A 67-year-old man with dilated cardiomyopathy was admitted to our hospital for treatment of cardiac failure. After using heparin because cerebral infarction developed during hospitalization, in acknowledgment of thrombocytopenia, we reach the diagnosis of HIT. We judged surgery to be necessary because heart failure had difficulty with catecholamine secession and the left ventricular dilation progressed rapidly, and performed left ventriculoplasty, mitral valve plasty. There were no complications such as the thrombosis during cardiopulmonary bypass, and the postoperative course was good without leading to re-thoracotomy due to bleeding. He passes without a heart failure symptom by the follow of one year 6 months after surgery at home.

Type A Aortic Dissection during the Treatment of Tuberculous Pericarditis / 日本心臓血管外科学会雑誌

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/<i>l</i>). 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.

A Case of Partial Aortic Root Remodeling for the Right Sinus of Valsalva Aneurysm with an Anomalous Origin of the Coronary Artery / 日本心臓血管外科学会雑誌

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.

A Case of Early Progressive Aortic Valve Regurgitation after Coronary Artery Bypass Grafting in Aortitis Patient with Negative Findings for C-Reactive Protein and the Erythrocyte Sedimentation Rate / 日本心臓血管外科学会雑誌

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.

Results of Abdominal Examinations by Sonography at Hokkaido Koseiren-Affiliated Facilities over the Past 10 Years / 日本農村医学会雑誌

  The Association of Radiologists under the umbrella of the Hokkaido Prefectural Federation of Agricultural Cooperatives for Health and Welfare (Hokkaido Koseiren) set up in 2003 a committee with the aim of improving the accuracy of mass health examinations. Recently, the committee reviewed the results of abdominal examinations by sonography performed at the eight hospitals affiliated with the Koseiren during fiscal 2006 that ended March 31, 2007. Of those individuals who underwent thorough health checkups, 91.3% had their abdomen examined by ultrasound. Something anomalous was detected in 68.1% of the examinees and 4.5% needed to undergo closer checkups, the rate of response to which was 74.5%. The detection ratio of cancer by ultrasonography was worked out at 0.048%. The ratio of patients requiring a closer exam to the total and the cancer detection ratio varied widely from hospital to hospital. The wide dispersion was ascribable to the difference in the standard of judgment for indicating closer examinations and the difference in the number of examinees so far as the cancer detection ratio was concerned, from hospital to hospital. A look at the primary findings of anomalies revealed that fatty liver topped the list accounting for 27.4% followed by cholelithiasis with 3.6%. From this, we realized that the abdominal examinations by sonography served to detect cancer and lifestyle-induced health problems as well. Organ-wise, the cancer cases found during the period from 1998 to 2009 broke down as follows: kidney (79 cases), liver (40 cases), pancreas (30 cases), gall bladder (24 cases), others (8 cases) and spleen (none). The cancer detection ratio per year ranged from 0.03 to 0.05% during the period.

Hybrid Endovascular Stent Graft Repair with Reconstruction of Superior Mesenteric and Celiac Arteries for a Ruptured Thoracoabdominal Aortic Aneurysm / 日本心臓血管外科学会雑誌

A 77-year-old woman was referred to our hospital for treatment of a ruptured thoracoabdominal aortic aneurysm (TAAA) with a maximum diameter of 7cm. Considering her age and level of daily activity, the placement of an endovascular stent graft was performed as an emergency rescue procedure. For termination of the endoleak from the distal portion of the stent graft detected by CT the next day, another stent graft placement was added after establishment of blood supply to the superior mesenteric and celiac arteries by placing a Y-shaped graft from the abdominal aorta to each artery with success. The patient was discharged from our hospital 25days after surgery with disappearance of endoleak and good graft patency. A hybrid technique with grafting to abdominal branches, followed by placement of stent graft, can be an alternative treatment for such high-risk patients with ruptured TAAA.

Utility of High-density Barium to Improbve the Quality of X-ray Images / 日本農村医学会雑誌

Aim:The usefulness of high-density barium, which was made to 150w/v% (MIX150), was examined to obtain better radiographs of the intestines. Methods: “MIX150” was compared with existing pharmaceutical “BAM100” to evaluate x-ray images (barium adhesion, dryness evaluation). MIX150 was used in 232 patients (mean age 56 years), while BAM 100 in 210 patients (mean age 55 years). Results: In terms of adhesion, MIX150 was excellent in the the cecum significantly and in dryness evaluation, in the entire region of the colon. Conclusion: High-density barium (150w/v%) was useful for enhancing the quality of radiographic images.

Acupuncture Therapy for Delirium with Diffuse Axonal Injury. A Case Report / 全日本鍼灸学会雑誌

We used acupuncture therapy to treat a Diffuse Axonal Injury (DAI) patient who had developed delirium that persisted for many months after the traffic accident. The patient was diagnosed with mania-depressive syndrome from an oriental medical perspective, and was treated for blood stagnation and depression of qi and qiblood energy deficiency. The selected meridian points were Baihui, Dazhui, Geshu, Dazhu, Qimen, Taichong, and Zusanli, to Promote improvement of cyclical flow of qi to the brain through the Bladder Meridian and Gorvenor Vessel Meridian. As the early results of acupuncture therapy headache disappeared and the Sleep-Wake Schedule Disorder improved to normal. After 40 sessions of acupuncture therapy, that consciousness level improved and the Japan Coma Scale (JCS) score indicated “alert”. From these results, it was suggested that the cyclical flow of qi to the brain was improved and blood stagnation had disappeared, therefore the symptoms improved. Based on the result of this treatment for a DAI patient, we understood the importance of considering the brain as a meridian, individual from the body.
