A case of intracranial mycotic aneurysm was reported, in whom repeated cerebral angiographies demonstrated the seccessive appearance of multiple aneurysms in a short term after the septic cerebral infection, and the importance of repeated angiography in the treatment of the intracranial mycotic aneurysm was stressed. A 44-year old male who had heart failure developed suddenly a left hemiparesis with irritable meningial signs on Nov. 3, 1973. The right carotid angiography carried out on Nov. 16 in an admitted hospital showed partial obliteration of cortical branches of the middle cerebral shift of the anterior cerebral artery due to the cerebral infarction. No aneurysm was demonstrated in the angiogram. The second angiography of the right carotid and vertebral artery was done on the admission of Dec. 18. The previously shown contralateral shift of the anterior cerebral artery was remarkably decreased, and an aneurysm of 3 mm in diameter was recognized at the cortical branch of the right middle cerebral artery on the parietal region. Any aneurysm was not revealed by the vertebral angiography. The third angiography of bilateral carotid and vertebral artery was performed on Dec. 25. The previously revealed aneurysm increased in size. Multiple aneurysms was demonstrated at the anterior branches of the insular artery. The vertebral angiography demonstrated multiple aneurysms at the peripheral portion of the bilateral posterior cerebral arteries. The patient was improved neurologically after the administration of antibiotics, and was discharged on Dec. 27 on the convenience of his family and would be followed in conservative cares.

A 55-year-old man with a mild fever and sweating developed severe headache for the days before admission. Cerebral computed tomography and selected cerebral angiography on the day of admission revealed subarachnoid hemorrhage due to rupture of an aneurysm of a distal branch of the left middle cerebral artery. Detection of vegetation on the aortic valve by two dimensional echocardiography confirmed the diagnosis of infective endocarditis with a ruptured mycotic cerebral aneurysm. Because of rapid growth of the vegetation on the aortic valve and progression of heart failure despite antibiotic therapy, emergency cardiac surgery was performed. To prevent re-rupture of the aneurysm, the aortic valve was replaced with a bioprosthetic valve, and no anticoagulant was administered postoperatively. Repeated cerebral angiography revealed that the aneurysm was becoming progressively smaller during the next 9 months. No cerebrovascular accident occurred postoperatively. We believe that it is safe to treat a ruptured mycotic cerebral aneurysm without involvement of a hematoma mass in the brain conservatively, and that use of a bioprosthetic valve, if valve replacement is mandatory, and avoidance of anticoagulant therapy during the postoperative period are advisable in the treatment of a patient with infective endocarditis and a ruptured cerebral mycotic aneurysm.

Thirty out of 287 patients (10.4%) admitted to hospital for infective endocarditis between December 1970 and January 1990 had neurological complications. Twenty-three patients had native valve infectious endocarditis and 7 had prosthetic valve endocarditis. The clinical features were characterized by the frequency of aortic valve involvement (23 out of 30) and other complications, especially cardiac failure (16 cases) and peripheral vascular manifestations (7 cases). The commonest organism was the staphylococcus (53% of identified organisms) but the number of negative blood cultures was high (50% of cases). The neurological complication was often the presenting symptom of the endocarditis (19 cases) but it occurred after bacteriological cure in 4 cases. The complications observed were cerebral ischemia (16 cases), cerebral haemorrhage (11 cases), coma (2 cases), and one peripheral neuropathy causing a Claude Bernard Horner syndrome. These complications presented with hemiplegia in 17 cases, a meningeal syndrome in 8 cases, a convulsion in 1 case, a Von Wallenberg syndrome in 1 case, and a Claude Bernard Horner syndrome in 1 case. Twelve patients had a transient or permanent neurological coma. Cerebral CT scan showed ischemic lesions in 7 cases and haemorrhagic lesions in 10 cases. Carotid angiography demonstrated mycotic aneurysms in 6 patients. Twelve patients died: the cause of death was neurological coma (7 cases), low cardiac output (4 cases) and haemorrhagic shock (1 case). Four patients underwent neurosurgery: 3 for clipping a mycotic aneurysm and 1 for drainage of an intracerebral haematoma. Poor prognostic factors were: coma, cardiac failure, cardiac valve prosthesis and, above all, the extent and multiplicity of the neurological lesions. The authors propose the following measures to improve the prognosis: early surgery in cases of large and/or mobile vegetations especially when the infecting organism is a staphylococcus and when a systemic embolism has occurred; routine CT scanning and/or digitised cerebral angiography in all patients with infective endocarditis to detect surgically accessible mycotic aneurysms.

We reported a 29-year-old man with active endocarditis complicating aortic and mitral valve regurgitation. The echocardiogram showed a mycotic aneurysm at aortic valvular annulus and a aneurysm of mitral valve. Heart failure was progressive and caused anuria. Prior to emergent double valve replacement, 2,500 ml of water was removed. Then hemodynamics became stationary. Urination was good during and after operation. In this case, complicating acute renal failure, dehydration with extracorporeal ultrafiltration method was very effective for improvement of hemodynamics.

The echocardiograms and clinical records of 70 patients with infective endocarditis seen between 1983 and 1988 were examined to evaluate the role of two-dimensional and Doppler echocardiography in the diagnosis of infective endocarditis and identify risk factors for morbidity and mortality. A blinded observer reviewed the echocardiograms for the presence and size of vegetations and the severity of the valvular regurgitation. Vegetations were identified in 54 (78%) of 69 technically satisfactory echocardiograms. In 38 patients whose heart was examined at surgery or autopsy, all vegetations diagnosed by echocardiography were confirmed, but six additional vegetations were found. Abnormal (greater than or equal to 2+) valvular regurgitation was present in 88% of patients. No patient with less than or equal to 1+ regurgitation (n = 8) died or required valve surgery for heart failure, but three of the eight patients did undergo surgery for mycotic aneurysm, recurrent embolism or paravalvular abscess. In patients without embolism before echocardiography, there was a trend toward a greater incidence of subsequent embolism in those with vegetations greater than 10 mm in size (26% [8 of 31] compared with 11% [2 of 18] with vegetations less than or equal to 10 mm) (p = 0.19). By multivariate analysis, risk factors for in-hospital death (n = 7) were an infected prosthetic valve (p less than 0.007), systemic embolism (p less than 0.02) and infection with Staphylococcus aureus (p = 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Presently we favor heparinless femorofemoral venoarterial bypass for all descending thoracic aneurysm resections. The advantages are minimal blood loss due to the absence of heparin, ease of insertion, especially in large aneurysms where it would be difficult to insert a temporary shunt, distal aortic perfusion, possibly a safety factor in preventing spinal cord and visceral ischemia, and prevention of left heart overload and myocardial failure. In acute traumatic ruptures, simple aortic cross clamping is a suitable alternative. It is safe and can be carried out expeditiously in any community hospital where bypass facilities may not be available. Proximal hypertension can be controlled pharmacologically. We have also used this successfully in ruptured atherosclerotic aneurysms. We have no experience with temporary tridodecylmethylamonium (TDMAC) shunts; several groups have used them successfully. We believe they may be difficult to insert in the proximal aorta with a large mediastinal hematoma or extensive aneurysm. Cannulation of the left ventricular apex necessitates cardiac manipulation and may produce effective aortic valve insufficiency. In patients with aortoesophageal and bronchoesophageal fistula, permanent extrathoracic bypass is preferable to a prosthetic graft in a contaminated field. We propose using a permanent bypass with a no. 10 or 12 right axillofemoral bypass. Our experience is limited to only two patients. This is also a method of treating a mycotic aneurysm or infected thoracic aortic graft.

We report a case of mitral valve replacement after ruptured mycotic aneurysm resection in acute phase of bacterial endocarditis. We have experienced a 68-year-old man with vegetation at the anterior leaflet of mitral valve and multiple systemic embolization. He underwent aneurysmectomy of ruptured mycotic cerebral aneurysm and embolectomy of left femoral artery eight days after subarachnoid hemorrhage. Mitral valve was replaced three days after successfully. If there was no heart failure preoperatively, valve replacement operation is recommended in acute phase of infected endocarditis or few days after cerebral aneurysmectomy.

From January, 1978, through December, 1990, surgical treatment for active infective endocarditis was performed in 11 patients. There were 8 men and 3 women who ranged in age from 19 to 54 years with a mean age of 38.8 years. Two patients had ventricular septal defects and 1 patient had rheumatic valve disease. In all patients, the infecting organism was isolated from blood, including streptococcus in 7, staphylococcus in 2, and gram-negative rods in 2. The indication for operation at the active phase was uncontrolled infection in 7 and progressive heart failure in 4. The operation was performed at 7 to 150 days with a mean of 53 days after diagnosis. Operative findings showed vegetations in all cases and perforations of the valve in 6. There were no operative deaths. Perioperative complications developed in 5, whose indication for operation was uncontrolled infection. Complications consisted of 1 prosthetic valve endocarditis, 1 pulmonary suppuration, 1 ruptured mycotic aneurysm of the hepatic artery, 1 ruptured mycotic aneurysm of the popliteal artery, and 1 pyogenic spondylitis. All were successfully treated surgically or with antibiotic therapy. There were no complications in patients whose indication for operation was progressive heart failure. We conclude that the risk of embolism is high in patients undergoing surgery at the active phase of infective endocarditis because of uncontrolled infection; thus, such patients should be carefully monitored for emboli.

Between 1969 and 1990 six patients (aged 14 to 64 years, mean 43 years) underwent in situ reconstruction for mycotic aneurysm of the ascending aorta. The primary source of infection was endocarditis in three patients (subacute bacterial endocarditis [n = one patient], sepsis with acute endocarditis [n = one patient]), sepsis with sternal osteomyelitis in one, sepsis with purulent pericarditis in one, and generalized febrile illness in one. In five of six patients the treatment consisted of the excision of changed tissue combined with a composite graft (n = one patient), a xenopericardial patch repair (n = one patient), a Dacron graft repair and aortic valve replacement (n = one patient), a Dacron graft repair alone (n = one patient), and a lateral suture combined with double valve replacement (n = one patient). In one patient with perforation of the mycotic aneurysm into the pulmonary artery, the place of rupture was oversewn without excision of the aortic or pulmonary artery tissue. Two patients with local pericardial inflammation were reoperated on during the hospital stay; one of them because of recurrent mycotic aneurysm of the ascending aorta at the other location and the other because of infection of the suture line after the Dacron patch repair. Antibiotic therapy was intravenously administered for 2 to 12 weeks postoperatively and continued orally for 4 to 8 weeks. The mean observation time was 6 years (range 4 months to 16 years). There was no late graft infection, except the chronic infection of the suture line in one patient who died suddenly 4 months after the operation. There was no early death, and there were three late deaths (chronic myocardial failure, one patient, chronic renal failure, one patient, sudden death, one patient). We concluded that in situ reconstruction for mycotic aneurysm of the ascending aorta combined with prolonged antibiotic therapy is an appropriate procedure with satisfactory early and good long-term results.

During 1993 to 2000 85 patients were treated for a ruptured abdominal aortic aneurysm. The average age of the patients was 72.4 years (46-90). 71 patients showed an infrarenal rupture and the remaining 14 a suprenal rupture. 76 of 85 cases were covered ruptures. All patients were operated upon. A tube graft was required in 43 cases and 31 needed a bifurcated graft. In further two cases an extraanatomical bypass was necessary due to a mycotic aneurysm. The operation on 11 patients could not be completed and 21 patients died in hospital during the postoperative period. On the other hand, 53 patients survived the rupture of the aneurysm. The mortality rate was 37.6 %. The early non-surgical complications dominated during the postoperative period. Respiratory failure, renal failure and cardiac failure were responsible for the mortality rate. It is unforseeable which patients will survive the emergency operation. Therefore it is always appropriate to attempt the reconstruction of an acutely ruptured AAA.
