Octreotide for Treatment of Chylorrhea after Internal Thoracic Artery Harvest / 日本心臓血管外科学会雑誌

<p>Chylorrhea is a rare complication after cardiothoracic surgery, occurring in 0.5-2% of patients. It is extremely rare after coronary artery bypass grafting. The initial management of chylorrhea is conservative, but if it is unsuccessful, surgical intervention is indicated. Recently, some cases treated with octreotide have been reported. We report two cases of chylorrhea after internal thoracic artery harvest treated with octreotide.</p>

Aspergillus Pseudoaneurysm and Endocarditis of the Aortic Valve after Coronary Artery Bypass Graft Surgery / 日本心臓血管外科学会雑誌

<i>Aspergillus </i>pseudoaneurysm of the ascending aorta is rare in patients who have undergone coronary artery bypass graft surgery (CABG), and there are few cases reports of patients with AIDS, or after transplantation. A 76-year-old man underwent CABG due to unstable angina in 2002 ; in 2005 and 2006, he suffered 3 episodes of pseudoaneurysm formation in the ascending aorta. The aneurysm was resected and the defect was repaired with a Dacron patch twice. Finally, aortic root replacement with the modified Bentall technique was performed, but pathological examination of the wall of the pseudoaneurysm showed <i>Aspergillus</i>. On day 13, the <i>Aspergillus </i>infection developed into septicemia, and he died.

Long-term Results with 90 Composite Graft Replacements of the Ascending Aorta and Aortic Valve / 日本心臓血管外科学会雑誌

From May 1975 to August 1991, 90 patients (56 males and 34 females) underwent Bentall's operations or its modified technique. In our modified technique the coronary ostium is cut out like a button and anastomosed to the aortic graft and aortic grafts are not wrapped by the aortic wall. Preoperative diagnoses were AAE (25 patients, 28%), Stanford type A dissection (19, 21%), Marfan's syndrome (16, 18%), aortitis syndrome (12, 13%), AR+ascending aortic aneurysm (6, 7%), syphilitic aortitis (5, 6%), AS+ascending aortic aneurysm (3, 3%), Valsalva's sinus aneurysm (2, 2%) and other diseases (2, 2%). The hospital mortality rate was 17% (15/90) for all cases. The hospital mortality for aortic dissection (37% (7/19)) and reoperation cases (75% (3/4)) were very high. There were 10 cases of late death and the 10 year actuarial survival rate was 66.3%. Among 11 cardiovascular events which occured in the late phase, 5 were dissection at other aortic sites in the type A dissection and Marfan syndrome cases, and 3 were pseudoaneurysm formation at the site of coronary or the aortic anastomosis in the aortitis syndrome cases, and a detachment of the composite graft in the Marfan's syndrome cases. The 10-year event-free rate was 92.0% for non-specific AAE, 68.8% for aortitis syndrome, 61.9% for Marfan's syndrome and 47.3% for Stanford type A dissection. Non-specific AAE had excellent long-term results, but Marfan's syndrome and dissection had poor results. The button technique for coronary reconstruction is effective for all cases and its long term results are good, but, even with this technique, coronary pseudo-aneurysm occured in cases of aortitis syndrome.

Retroperitoneal Approach to Abdominal Aortic Aneurysms / 日本心臓血管外科学会雑誌

To evaluate the efficacy of the retroperitoneal approach (RP) when compared with the transperitoneal approach (TP) in elective aortoiliac reconstruction, 41 cases were reviewed. From February 1987 through October 1991, 16 patients underwent aortoiliac reconstruction through the TP approach and 25 patients underwent operation through the RP approach for abdominal aortic aneurysms (AAA). The TP approach was associated with larger intraoperative blood loss (648.6±416.5ml) when compared with the RP approach (357.7±208.9ml) (<i>p</i><0.01). The TP approach was associated with greater intraoperative blood transfusion (2093.8±1179.0ml) when compared with the RP approach (1010.4±905.3ml) (<i>p</i><0.01). Both groups had similar operative times. Postoperative initiation of oral water intake was prolonged in the TP group (50.2±27.4hr) when compared with the RP group (22.3±8.9hr) (<i>p</i><0.01). Postoperative initiation of walking training was prolonged in the TP group (88.7±37.1hr) when compared with the RP group (60.1±23.2) (<i>p</i><0.01). This experience demonstrates that the RP approach is a preferable alternative to the TP approach in elective aortoiliac reconstruction.
