ABSTRACT
A 71-year-old man who had undergone repair of a ruptured abdominal aortic aneurysm with a tube graft 3 months ago was transferred from another hospital with an Aortoenteric Fistula (AEF) for surgical treatment. Computed tomographic (CT) angiography revealed pseudoaneurysm formation at the proximal anastomotic site. Waiting for the elective operation, he developed massive hematemesis with shock. Endovascular stent-graft repair was emergently performed because of high risk for conventional open surgery. Gastrointestinal bleeding was successfully controlled. The psuedoaneurysm disappeared, which was confirmed by postoperative CT angiography. At 1-year follow-up, he has shown no clinical and radiographic evidence of recurrent infection or bleeding. For the case with shock, Endovascular repair could be a bridge to open surgery because it is fast and minimally invasive. Endovascular repair of AEF is technically feasible and may be the definitive treatment in selected patients without signs of infection and gastrointestinal bleeding.
ABSTRACT
We reported a 74-year-old female complicated by ostial obstruction of the left main trunk after aortic valve replacement for severe aortic stenosis. At surgery, the length from the orifice of the left main trunk to the aortic annulus was 3 mm. After a 19 mm Carpentier-Edwards PERIMOUNT MAGNA was implanted in supra-annular position, the orifice of left main trunk was concealed by a sewing cuff of the bioprosthesis. Before aortic declamping, saphenous vein graft was bypassed to the left anterior descending artery. The postoperative course was uneventful. Computed tomography demonstrated the ostial obstruction of the left main trunk by the bioprosthesis.
ABSTRACT
The purpose of this study was to evaluate the efficacy of early rehabilitation starting on the day after cardiac surgery. In the early rehabilitation program, introduced from November 2006, we adopted an original video program about hospitalization and daily multi-specialist conference in the ICU. We divided 179 patients who underwent elective cardiac operation from June 2004 to September 2007 (mean age 65.4 years old, 51 women, 91 CABG, 53 valve procedures and 35 other procedure) into group A (the initial rehabilitation group : <i>n</i>=73) and group B (the early rehabilitation group : <i>n</i>=106). There were no significant differences in patient profile (age, gender, operation time etc.) between the two groups. The mean postoperative day of starting cardiac rehabilitation was 4.3+/-1.6 days in group A and 1.5+/-1.0 days in group B (<i>p</i><0.01). The mean achievement period of all walking distances in group B was significantly shorter than in group A as follows, 50 m : group A 5.4+/-2.2 vs. group B 3.1+/-1.5 days (<i>p</i><0.01), 100 m : group A 6.9+/-3.1 vs. group B 4.9+/-2.2 days (<i>p</i><0.01), 200 m : group A 8.5+/-3.9 vs. group B 6.5+/-2.5 days (<i>p</i><0.01), 300 m : group A 10.2+/-3.9 vs. group B 8.1+/-2.9 days (<i>p</i><0.01), 500 m : group A 14.5+/-6.1 vs. group B 11.9+/-3.8 days (<i>p</i><0.05). Approximately 90 per cent of patients in group B could walk by themselves on leaving the ICU. There were no major complications throughout rehabilitation. The mean hospital stay was 31.0+/-11.2 days for group A and 25.9+/-7.4 days for the group B, with a statistically significant difference (<i>p</i>=0.03). In a questionnaire survey at discharge, 91.0 per cent of patients in group B answered that early rehabilitation was most gratifying. In conclusion, early rehabilitation after cardiac surgery is effective for early recovery of ADL and leads to shorter hospital stay. We think both preoperative education and daily conferences are indispensable for safe and effective early rehabilitation programs.
ABSTRACT
Destructive aortic valve endocarditis or poor controlled aortitis cause the development of left ventricular-aortic discontinuity. We reported our experience with aortic root replacement for cases of severe aortic annular destruction. Between 1999 and 2006, 9 patients with severe aortic annular destruction underwent aortic root replacement at our institute. There were 8 men and one women with a mean age of 55 years. Seven patients were in New York Heart Association functional class III. Four of 9 patients had native valve endocarditis, 4 had prosthetic valve endocarditis (previous aortic valve replacements in 2, aortic root replacements in 2) and one had active aortitis with a detached mechanical valve. Radical debridement of the infected cavity and necrotic tissue was performed in all cases, followed by reconstruction of the aortic annulus using autologous or xenogenic pericardium in 3 cases. Antibiotic-saturated fibrin glue was applied to the cavity. Aortic root replacement was achieved with a pulmonary autograft (Ross procedure) in 4 and stentless aortic root xenograft in 4. One patient who had advanced liver cirrhosis underwent aortic valve replacement with a stentless xenograft by subcoronary implantation method. No mortality was observed during hospitalization and follow-up. Reoperation within 5 years was not necessary in 66.7% of the patients. Excellent outcome can be achieved by radical exclusion of the abscess cavity and viable pulmonary autograft or stentless aortic root xenograft in patients with severe aortic annular destruction.
ABSTRACT
A 45-year-old man underwent total arch replacement for acute type A aortic dissection. Vital signs during the operation remained stable, but sinus tachycardia was recognized about 7h postoperatively, followed by a high level of PaCO<sub>2</sub>, low level of PaO<sub>2</sub> and metabolic acidosis. Then, blood pressure decreased, accompanied rapid elevation of body temperature to 39.7°C. Body temperature was decreased gradually by cooling the whole body, however, coma, anuria and hypoxemia persisted. A diagnosis of malignant hyperthermia was made and Dantrolene was administered. However, the patient died of multiple organ failure 7 days postoperatively. The serum level of CPK increased to 12, 446IU/<i>l</i> and serum myoglobin elevated to a very high level (36, 500ng/ml) 2 days postoperatively. Although, it is very rare for malignant hyperthermia to develop after open-heart surgery, physicians must keep this disease in mind if sudden hyperthermia of unknown origin is demonstrated.
ABSTRACT
A 70-year-old-woman was admmitted to receive an operation for aortic arch aneurysm. Total arch replacement was carried out under deep hypothermic circuratory arrest with selective cerebral perfusion. During sternal closure, her blood pressure dropped to 60/30mmHg suddenly, and massive venous bleeding started from the substernal space which turned out to be hemorrhage from the laceration of the pulmonary trunk. Controlling the bleeding by finger compression, rapid introduction of cardiopulmonary bypass was carried out and the laceration was closed by a pericardial patch. The postoperative course was uneventful. In this case, compression of the pulmonary trunk by the aortic arch aneurysm may have caused the fistula formation between them, and decompression of the aneurysm probably induced the rupture of the pulmonary trunk. If the preoperative computed tomogram had showed the compression of the pulmonary artery by the aneurysm, a careful exploration of the main pulmonary artery and a removal of the thrombus should have been performed, even when the preoperative diagnostic evaluation failed to reveal aortopulmonary fistula.
ABSTRACT
An 81-year-old woman developed abdominal pain after off-pump CABG (OPCAB) for unstable angina pectoris. X-ray film and CT scan showed paralytic ileus the day after surgery. A presumptive diagnosis of mesenteric ischemia was made and exploratory laparotomy was performed. During surgery, however, there was no sign of mesenteric ischemia. The patient still complained of abdominal pain after the laparotomy, so selective angiography of the mesenteric artery was performed. The angiography showed remarkable vasospasm of the superior mesenteric artery (SMA) and diagnosis of nonocclusive mesenteric ischemia (NOMI) was made and continuous intra-arterial perfusion of papaverine into the SMA was started. Control angiography during papaverine perfusion showed a clear reduction of vasospasm. Thereafter, the patient developed diffuse peritonitis due to intestinal gangrene on postoperative day 12 and was compelled to undergo extensive resection of the intestine and sigmoidectomy. She could not be weaned from the ventilator due to respiratory insufficiency and died of multiple organ failure about 5 months after OPCAB. NOMI can develop even in OPCAB, in which cardiopulmonary bypass is not required. Therefore maintenance of stable hemodynamics intraoperatively, careful management of the postoperative state and early diagnosis and therapy are essential to prevent NOMI.
ABSTRACT
A 65-year-old-man was admitted with congestive heart failure and septic shock associated with suspected mitral valve infective endocarditis. An echocardiogram revealed vegetation attached to the chordae, high density lesions in both papillary muscles, and severe mitral regurgitation. An emergency operation was performed. Vegetation was been attached to the chordae. Multiple myocardial abscesses were noted in both papillary muscles and surrounding myocardium. However, there were few noticeable lesions on mitral valve leaflets and annulus. The anterior mitral leaflet was resected together with the chordae and the papillary muscles containing the myocardial abscesses. Mitral valve replacement was performed using a 27mm SJM valve after the other myocardial abscesses were drained. <i>Klebsiella pneumoniae</i> was cultured from the vegetation and the myocardial abscesses. Cases of myocardial abscess associated with infective endocarditis at the site of the papillary muscles and in the areas of the myocardium are very rare. It was assumed that the myocardial abscesses were probably due to the septic state from infective endocarditis, since myocardial abscesses was recognized in multiple sites and at a distance from the valve leaflets and annulus.
ABSTRACT
A successfully treated case of a 73-year-old man with mycotic aneurysm of the iliac artery combined with psoas abscess was reported. The operation consisted of débridement of the infected arterial wall with arterial reconstruction using autologous reversed superficial femoral vein and wrapping the graft and filling the defects with omentum. <i>Streptococcus pneumoniae</i> was grown from the psoas abscess culture. He had peritonitis by gangrenous cholecystitis postoperatively and underwent reexploration for correction of the peritonitis. After his second operation, the postoperative course was uneventful. He is doing well 18 months postoperatively. Venous morbidity after superficial femoral vein harvest is minimal. <i>In situ</i> reconstruction with autogenous deep leg veins is a successful option in patients with mycotic aneurysms.
ABSTRACT
A 62-year-old man was admitted because of cardiac failure caused by mitral valve regurgitation. After his cardiac and general conditions had been evaluated, he underwent an operation. Some of chordae tendineae of both leaflets were ruptured and both leaflets had deformities. Since his mitral valve could not be repaired, it was replaced with a 29mm Hancock II bioprosthesis. Two weeks after operation, transesophageal echocardiography (TEE) and left ventriculography revealed that one of the three leaflets of the prosthesis was fixed in the closed position, and mild mitral valve stenosis without regurgitation was recognized. But he had no complaints and there were no other major disorders. He was observed every 2 weeks as an outpatient. Six months after operation, TEE showed good opening and closing of all 3 leaflets and showed no major abnormalities, although the cause of the failure was unknown. He is healthy 2 years after operation, but is being observed carefully.
ABSTRACT
We report an unusual case of a 71 year-old man who developed chronic consumption coagulopathy caused by an abdominal aortic aneurysm. He was diagnosed as having the dissecting aortic aneurysm (DeBakey type IIIa) and the abdominal aortic aneurysm in 1989, and had been attending to our hospital as an outpatient since then. He developed macrohematuria in March 1990. The laboratory data showed the decrease in platelet, fibrinogen, plasminogen and α<sub>2</sub> plasmin inhibitor and the increase in FDP. The bleeding tendency was controlled by the administration of gabexate mesilate and heparin, but the laboratory data revealed that consumption coagulopathy continued. The abdominal aortic aneurysm was successfully replaced with a prosthetic vascular graft in June 1992. Postoperative hematological findings revealed the improvement, and he discharged 32nd day and doing well after operation.
