ABSTRACT
The case is that of a 90-years-old man. A previous doctor performed abdominal graft replacement for an abdominal aortic aneurysm 5 years earlier and continued outpatient CT follow-up. Follow-up CT showed the right aortic arch and dilation of the thoracic aortic aneurysm, and the patient was referred to our hospital. Contrast-enhanced CT showed an aortic arch aneurysm ; the aneurysm diameter was 62 mm in major axis and 60 mm in minor axis, which was judged to be suitable for surgery. It was a rare right-sided aortic arch with no congenital heart malformation and no situs inversus. Endovascular treatment was considered because he was 90 years old and very elderly, but there were concerns about the risk of embolism, irregular manipulation and central landing. For the surgical method, we selected total arch replacement using a frozen elephant trunk technique. We succeeded in avoiding serious complications by selecting an appropriate treatment method through careful evaluation.
ABSTRACT
Right sided infective endocarditis (RSIE) is uncommon. Patients are traditionally treated with antibiotics alone, and indications for operation are not clearly established. A 23-years-old man who developed fever and general fatigue was referred to our hospital on the suspicion of RSIE. A ventricular septal defect (VSD) and untreated dental caries had been previously diagnosed. Transthoracic echocardiography revealed vegetation on the tricuspid valve and severe regurgitation. The tricuspid valve was repaired ; the anterosuperior leaflet was partially resected and repaired with fresh autologous pericardium and the use of synthetic chordae. Recurrence of infection and tricuspid valve regurgitation were not observed for 1 year after this operation.
ABSTRACT
<b>Background</b> : This study was performed to evaluate surgical outcomes after cardiovascular surgery (including urgent surgery) in patients 85 or older. <b>Methods</b> : A retrospective analysis was performed on 39 patients (mean age, 86.3 years ; age range, 85-90 years) who underwent total arch replacement (<i>n</i>=4), ascending aorta replacement (<i>n</i>=4), descending aorta replacement (<i>n</i>=1), aortic valve replacement (AVR ; <i>n</i>=13), mitral valve replacement or valvuloplasty (<i>n</i>=3), coronary artery bypass grafting (CABG ; <i>n</i>=9), CABG+AVR (<i>n</i>=4), tumor resection (<i>n</i>=1) between June 2008 and December 2012 at Dokkyo Medical University Hospital. <b>Results</b> : Six hospital deaths occurred. One patient died due to bleeding from a ruptured descending thoracic aortic aneurysm, and another patient died due to gastrointestinal perforation from non-occlusive mesenteric ischemia (NOMI) after urgent AVR. The other deaths were related to various complications, including lung cancer, cholecystitis, myocardial infarction, and Takotsubo cardiomyopathy, during the postoperative period. Overall 30-day mortality was 2.6%, hospital mortality was 12.8%, duration of hospital stay after surgery was 41.3 days, duration of intensive care unit (ICU) stay was 3.8 days and ventilator time was 49.1 h. Twenty patients underwent elective surgery, and 19 patients underwent urgent surgery. The two groups had similar preoperative characteristics, except for the number of patients with aortic disease. No significant difference was evident in hospital mortality (26.3% vs. 5%, <i>p</i>=0.065) or 30-day mortality (0% vs. 5.3%, <i>p</i>=0.3) when comparing the two groups. However, the duration of hospital stay (58.9 days vs. 27.5 days, <i>p</i>=0.049), ICU stay (6.74 days vs. 1.05 days, <i>p</i>=0.002) and ventilator time (89.9 h vs. 8.2 h, <i>p</i>=0.006) was significantly longer in the urgent surgery group than in the elective surgery group. Fourteen patients (70%) in the elective surgery group and four patients (21.1%) in the urgent surgery group were able to be discharged from the hospital to their homes within 30 days after surgery. These data demonstrated that cardiovascular surgery in patients 85 years of age or older was associated with satisfactory outcomes, and outcomes associated with elective surgery were even better than those associated with urgent surgery. <b>Conclusions</b> : Therefore, advanced age does not represent a contraindication of conventional cardiovascular surgery. Rather, the decision for surgery should take the patient's preoperative condition, the severity of concurrent medical disease, the wishes of the patient, and the predicted functional outcomes into account.
ABSTRACT
Aortic dissection with multiple familial members is rare. It is commonly associated with Marfan syndrome. Several authors have reported familial aortic dissection without Marfan syndrome. We encountered 4 cases of aortic dissection in a family. The aortic dissection occurred in the mother and all of her children. No case had clinical manifestations of Marfan syndrome or other connective tissue disease. Histopathological examination of the aorta did not show cystic medial necrosis in 2 operated cases. Many members in the family had systemic arterial hypertension. The presence of multiple incidence of aortic dissection in one family suggests underlying connective tissue disease, irrespective of the absence of typical features of Marfan syndrome. Therefore we propose that other close relatives as well as the members with aortic dissection should be followed-up in the same way used for families with typical connective tissue disease like Marfan syndrome.
ABSTRACT
We recently experienced a case of Y graft replacement for recurrent blue toe syndrome (BTS) following cardiac catheterization. A 64-year-old male, who had undergone cardiac catheterization, complained of bilateral multiple toe cyanosis and pain. Angiograms revealed that infrarenal aortic stenosis was the recurrent embolic source. He refused surgical treatment because he thought the BTS was an iatrogenic complication. No conservative therapy was effective. He finally suffered from right foot and all left toe necrosis after nine months. Then he recieved Y graft replacement. Thereafter no embolic episode was seen. Cardiac catheterization recently has become a routine examination. However, informed consent is very important because it is difficult to anticipate BTS following the examination. Surgical treatment is recommended for recurrent BTS because conservative therapy fails in most cases.
