ABSTRACT

In the postoperative treatment of ruptured abdominal aortic aneurysm surgery, the relationship between intra-abdominal pressure (IAP) and the clinical course is not been clearly understood. From April 2000 to January 2003, we treated 109 cases of abdominal aortic aneurysm surgery (non-rupture 71 cases, rupture 38 cases) and measured intra-abdominal pressure in 30 of the ruptured cases which we analyzed in this study. The patients were divided into 2 groups. The H-group included 12 patients with maximum IAP equal to or higher than 20mmHg, and the L-group included 18 patients with a maximum IAP less than 20mmHg. Clinical characteristics were compared between the 2 groups. The mean age was 79.3±7.6yr in the H-group and 70.7±10.1yr in the L-group (<i>p</i>=0.019). Preoperative shock was diagnosed in 83.3% of the H-group patients, and 61.1% of the L-group patients the (<i>p</i>=0.26). Postoperative maximum values of intra-abdominal pressure were 22.3±2.0mmHg in the H-group, and 15.4±2.4mmHg in the L-group. Duration of intubation was 87.7±110.0h in the H-group, and 25.1±29.2h in the L-group (<i>p</i>=0.04). Food intake was started 14.4±11.2d after surgery in the H-group, and 8.5±4.8d after surgery in the L-group (<i>p</i>=0.094). The length of ICU stay was 6.7±6.5d in the H-group, and 2.9±2.1d in the L-group (<i>p</i>=0.033). Length of hospital stay after surgery was 54.1±25.8d in the H-group, and 25.2±6.8d in the L-group (<i>p</i>=0.001). Complications occurred in 8 cases out of 11 surviving cases (73%) in the H-group, and in 3 cases out of 17 surviving cases (18%) in the L-group (<i>p</i>=0.0024). Complication in the H-group included acute renal failure, paralytic ileus, respiratory failure, abdominal wall dehiscence, and acute arterial occlusion, and that in the L-group included acute renal failure, upper limb paresis, and lower limb paresis. Monitoring of intra-abdominal pressure was considered beneficial to recognize complication and decide therapeutic strategy after ruptured aortic aneurysm surgery.

ABSTRACT

A 70-year-old patient underwent modified maze procedure and mitral repair including quadrangular resection, annular plication (Reed procedure), and flexible ring annuloplasty with Cosgrove ring. Systolic anterior motion (SAM) of the anterior mitral leaflet and mild mitral regurgitation was observed on weaning from cardiopulmonary bypass. The patient was medically treated, and postoperative echocardiography revealed disappearance of the SAM 11 days after surgery. In addition to the surgical condition of rather excessive annular plication and small ring, transient conditions including inotropic support, insufficient volume under diastolic dysfunction of left ventricle, and loss of atrial contraction were thought to be the causes of SAM.

ABSTRACT

Fourteen patients with 22 solitary aneurysms of the iliac artery were operated in a 16-year period (1983 to 1999). Patients were divided into two groups. The non-ruptured group consisted of 6 patients who underwent surgical intervention before aneurysm rupture, and their mean age was 78.5 years. The ruptured group consisted of 8 patients who underwent surgical intervention for aneurysm rupture, with a mean age of 68.5 years. Although seven patients underwent emergency surgery for aneurysm rupture, less than half of them were operated upon within 24hr after the onset of aneurysm rupture. The average size of aneurysms was similar in the two groups (common iliac artery aneurysms: non-ruptured 47mm vs. ruptured 44mm in diameter, internal iliac artery aneurysms: non-ruptured 55mm vs. ruptured 55mm). Two patients died in the ruptured group, in which the operative mortality rate was 25%. Six patients (75%) of the ruptured group had hypovolemic shock, and two of them died during surgical repair. Of the patients with shock, two patients had intestinal ischemia after operation. Intestinal ischemia was one of the serious complications of ruptured iliac aneurysms. These results suggest that in patients with shock from ruptured iliac artery aneurysms, strategy for treatment is an important determinant of the outcome.

ABSTRACT

The purpose of this study was to consider the cause of the prolonged inflammatory reaction that sometimes appears after endovascular stent-graft repair for dissecting aortic aneurysm. Endovascular stent-grafting was performed in 12 patients (11 men and 1 woman, mean age 60±9.8). Endovascular stent-grafting was indicated to close the entry of type B dissections in 10 patients and to exclude ulcer-like projections (ULP) in 2 patients. On the 7th postoperative day (POD), aortography showed no endoleak in 7 type B cases (A-group), remaining endoleak in 3 type B cases (B-group), and complete exclusion in 2 ULP cases (C-group). The value of FDP-E in the A-group was high on the first POD and then decreased gradually. FDP-E also increased up to the 7th POD in the B-group, and increased very slightly after the operation in the C-group. The values of WBC and CRP increased up to the 3rd POD in all groups, but in the A-group it was still high on the 7th POD. On contrast-enhanced CT performed after the procedure and on the 7th POD, edema (over 10mm in thickness) around the descending thoracic aorta was demonstrated in 5 out of 7 cases in the A-group, but in none of the cases in the B- and C-groups. A segmental atelectasis in the left lung was detected in 6 out of 7 cases in the A-group, but in none of the cases in the Band C-groups. In the A-group, endovascular stent-grafting influenced thrombus formation, and the thickened edema around the descending thoracic aorta and the atelectasis produced in the left lung were prominent more than in the other groups. These results suggest that the Inflammation around aortic wall induced by thrombosis in the false lumen, might contribute to the development of the edema around the descending thoracic aorta and the atelectasis in the left lung. We conclude that the inflammatory reaction might have prolonged the postoperative course in the A-group patients.

ABSTRACT

A 49-year-old man who had no history of cardiac disease or intravenous drug abuse was referred to our hospital complaining of fever despite antibiotic chemotherapy. Blood culture was positive for <i>Streptococcus agalactiae</i>, and transesophageal echocardiography revealed vegetation attached to the tricuspid valve and moderate tricuspid regurgitation. Two-thirds of the anterior leaflet and a part of the posterior leaflet of the tricuspid valve were excised with the vegetation, and the remaining anterior leaflet was sutured to the posterior leaflet after annular plication. DeVega's annuloplasty was added to a diameter of two fingers. Following this procedure tricuspid regurgitation was minimal.

ABSTRACT

There were 16 patients who developed acute renal failure (ARF) follwing cardiovascular operation using extracorporeal circulation. They were treated by either CPD or CAVH because their ARF were resistant to medical treatment. These patients were divided into three groups according to their treatment; 7 patients treated by CPD (Group A), 5 patients treated both CPD and CAVH (Group B), 4 patients treated by CAVH (Group C). The survival rate was 33% in Group A, 20% in Group B, and 0% in Group C. The prognosis of the each group was poor. CPD and CAVH were effective to control the concentration of serum potasium and water removing. But CPD and CAVH were not very effective to control the concentrations of serum creatinine and blood urea nitrogen. There were three patients who developed low proteinemia which was one of the side effects of CPD. Seven of nine patients treated by CAVH, developed bleeding. The side effects of CAVH were seemed to be more severe than those of CPD.
