Supradiaphragmatic approach for Budd-Chiari syndrome with transjugular intrahepatic portosystemic shunt stent in combination with inferior vena cava reconstruction during living donor liver transplantation: a case report

Treatment of Budd-Chiari syndrome consists of medical management, surgical shunt, transjugular intrahepatic portosystemic shunt (TIPS), and liver transplantation. Liver transplantation is indicated only when other treatments have failed. A 36-year-old Japanese man underwent living-donor liver transplantation after radiologic intervention procedures. Because of the position of the TIPS stent and the damaged vascular lesion of Budd-Chiari syndrome, a supradiaphragmatic approach was employed to achieve a safe total hepatectomy. Moreover, after resection of damaged portion of the inferior vena cava (IVC), an artificial vascular graft was utilized to fill the IVC gap. The postoperative course was uneventful; no serious complications were experienced within 2 years after liver transplantation. This supradiaphragmatic IVC approach and IVC reconstruction technique emphasized the option of surgical techniques to decrease the operative risk during liver transplantation for Budd-Chiari syndrome.

Sialadenoma papilliferum with potentially malignant features

Sialadenoma papilliferum (SP) is a benign non-invasive lesion with slow and limited growth. This report describes an unusual SP that enlarged rapidly and presented as an extensive intraoral tumour highly suspicious for verrucous carcinoma. Radiographic resorption of the underlying bone was evident in the mandible. This type of destructive growth does not conform to any previously reported SP. Histological features were also atypical: surface verrucous hyperplasia and deeper florid cystic-duct adenoma. Overall, the SP is likely to be considered a borderline lesion with malignant potential. Four published cases of malignancy associated with SP showed completely different clinical and pathological settings, further obfuscating the concept of malignant SP.

Increased levels of angiopoietin-2 in induced sputum from smoking asthmatic patients

BACKGROUND

Active cigarette smoking has detrimental effects on asthma morbidity and severity. Angiopoietin-1 has been shown to protect the microvessels against plasma leakage, whereas angiopoietin-2 enhances vascular permeability and subsequently induces airway mucosal oedema. Therefore, it is recently thought that angiopoietin-2 may contribute to the pathophysiology of asthma.

OBJECTIVE

To determine whether angiopoietin-2 levels in the airways are associated with clinical profiles in smoking asthmatics.

METHODS

We measured angiopoietin-1 and -2 levels in induced sputum in 35 normal controls (18 non-smokers and 17 smokers) and 49 asthmatics (24 non-smokers and 25 smokers) before and after inhaled beclomethasone dipropionate (BDP: 800 microg/day) therapy for 12 weeks.

RESULTS

Angiopoietin-1 and -2 levels in induced sputum were significantly higher in asthmatics than in normal controls. Moreover, angiopoietin-2 levels were significantly higher in smoking asthmatics than in non-smoking asthmatics (P=0.0001). The airway vascular permeability index was also higher in smoking asthmatics than in non-smoking asthmatics. Moreover, the angiopoietin-2 level was positively correlated with the airway vascular permeability index (non-smoking asthmatics: r=0.87, P<0.001, smoking asthmatics: r=0.64, P=0.002). After BDP therapy, angiopoietin-1 levels were significantly decreased in non-smoking asthmatics, smoking-cessation asthmatics, and active-smoking asthmatics. In contrast, angiopoietin-2 levels did not differ from before to after BDP therapy in non-smoking asthmatics and active-smoking asthmatics. However, its levels were significantly decreased from before to after BDP therapy in smoking-cessation asthmatics (P=0.002). Although forced expiratory volume in 1 s (FEV(1))/forced vital capacity (FVC) before BDP therapy was comparable in all subgroups, this parameter after BDP therapy was significantly lower in active-smoking asthmatics than in non-smoking and smoking-cessation asthmatics. Moreover, the reduction in angiopoietin-2 levels after BDP therapy in smoking-cessation asthmatics was significantly correlated with an improvement in FEV(1)/FVC.

CONCLUSION

Angiopoietin-2 levels were elevated in the airways of smoking asthmatics, and its levels were associated with impaired airway responses.

Correlations of health-related quality of life questionnaire results in asthma and allergic rhinitis: effects of a leukotriene receptor antagonist

Bronchial asthma and allergic rhinitis frequently coexist. This study investigated correlations of health-related quality of life (QOL) questionnaires for these diseases, assessing whether the selective leukotriene receptor antagonist (LTRA), pranlukast, had additional benefits to overall asthma control when there was concomitant allergic rhinitis. Patients with asthma-associated allergic rhinitis were randomly allocated to either LTRA(+) (n = 21, treated for 3 months with pranlukast), or LTRA(-) (n = 8, no pranlukast). At study start and at 3 months, pulmonary function was evaluated and QOL assessments were made using the Asthma Health Questionnaire-Japan (AHQ-Japan) and the Japan Rhino-conjunctivitis Quality of Life Questionnaire (JRQLQ). Total scores were significantly correlated both before and after therapy. After 3 months' therapy, pulmonary function and total AHQ-Japan and JRQLQ scores significantly improved in the LTRA(+) group, but not in the LTRA(-) group. A significant correlation between change at 3 months in the AHQ-Japan and JRQLQ scores from baseline values was seen in the LTRA(+) group. LTRA therapy improved allergic rhinitis symptoms, asthma symptoms and pulmonary function.

Tumour budding at invasive margins and outcome in colorectal cancer

OBJECTIVE

Tumour budding, defined as small clusters of undifferentiated cancer cells at invasive margins, has been shown to reflect biologic aggressiveness of colorectal cancers. We therefore examined the prognostic significance of tumour budding in patients with colorectal carcinoma, particularly focusing on comparisons with other clinicopathological findings.

METHOD

Tumour budding was investigated in surgically resected specimens from 159 patients with colorectal carcinoma. With haematoxylin and eosin stained slides containing the entire invasive margin, the degree of tumour budding was classified into three grades: mild, <1/3 of the entire invasive margin; moderate, 1/3-2/3; marked, >2/3.

RESULTS

Mild tumour budding was found in 54 (34%) cases, moderate in 59 (37%) cases and marked in 46 (29%) cases. The degree of budding was linked with poor tumour differentiation, lymph node metastasis and advanced TNM stage (P < 0.001). In univariate analysis, patients with marked tumour budding [5-year cancer-related survival (CRS)/recurrence-free survival (RFS), 39%/53%] had significantly worse survival [CRS, hazard ratio (HR), 4.561; 95% confidence interval (CI), 2.265-9.184; P < 0.001; RFS, HR, 3.240; 95% CI, 1.430-7.342; P = 0.005] than those with mild (5-year CRS/RFS, 80%/82%) or moderate (63%/66%) budding. In the Cox regression model, marked tumour budding (HR, 3.137; 95% CI, 1.517-6.487; P = 0.002) and advanced tumour stage (stage III, HR, 3.226; 95% CI, 1.475-7.053; P = 0.003; stage IV, HR, 24.443; 95% CI, 10.843-55.100; P < 0.001) proved to be an independent predictor of short CRS.

CONCLUSION

Tumour budding is a practical and significant histological index for identification of high malignant potential and poor outcome in patients with colorectal carcinoma.

Haemodynamic changes in the liver under balloon occlusion of a portal vein branch: evaluation with single-level dynamic computed tomography during hepatic arteriography

AIM

To assess haemodynamic changes in the liver under temporary occlusion of an intrahepatic portal vein.

MATERIALS AND METHODS

Between February 2000 and October 2004, 16 patients with hepatobiliary disease underwent single-level dynamic computed tomography during hepatic arteriography (SLD-CTHA) under temporary balloon occlusion of an intrahepatic portal vein. All patients needed percutaneous transhepatic portography for therapy of their disease. SLD-CTHA was undertaken to clarify the time-attenuation curve influenced by portal vein occlusion, and it was performed continuously over a period of 30s. The difference in absolute attenuation of the liver parenchyma in segments with occluded and non-occluded portal vein branches was determined by means of the CT number, and the difference in absolute attenuation of the occluded and non-occluded portal veins themselves was also evaluated.

RESULTS

SLD-CTHA demonstrated a demarcated hyperattenuation area in the corresponding distribution of the occluded portal vein branch. The attenuation of the liver parenchyma supplied by the occluded portal vein was significantly higher than that in the non-occluded area (p<0.01). The balloon-occluded portal branch enhancement in 15 of 16 cases (94%) appears due to arterio-portal communications. Failure to evaluate a remaining case for portal branch enhancement was due to absence of a visualized portal branch in the section.

CONCLUSION

Under temporary occlusion of an intrahepatic portal vein, hepatic angiography produced enhancement of the occluded portal branches and their corresponding parenchymal distribution; this finding is considered consistent with the presence of arterio-portal communications.

[Durability of aortic root preservation using gelatin-resorcin-formalin glue in acute type A aortic dissection]

During the last 9 years, aortic root preservation using gelatin-resorcin-formalin (GRF) glue was performed in 63 patients as a part of surgery for acute type A aortic dissection. Residual aortic regurgitation (AR) was evaluated, grading 0 to IV+ by echocardiography. The survival and root reoperation-free rates were also assessed. The operative mortality was 9.5% (6 patients). Early postoperative AR < or = I+, = II+ and > or =III+ were 93, 7 and 0%, respectively. Late postoperative AR > or =III+ was observed in 4 patients. Root reoperation was performed in 4 patients (7.0%). In a case of reoperation, medial degeneration was found in the aortic wall, suggesting toxic effect of GRF glue. The actuarial survival and root reoperation-free rates at 9 years were 73 and 80%, respectively. In conclusion, aortic root preservation with the proper use of GRF glue has long-term durability with very low adverse effect.

Comedolytic effect of topically applied active vitamin D3 analogue on pseudocomedones in the rhino mouse

BACKGROUND

Retinoids and active vitamin D(3) analogues regulate the proliferation and differentiation of keratinocytes and are effective in the treatment of psoriasis. Retinoids are known to be effective against acne vulgaris through comedolysis. However, the comedolytic effect of active vitamin D(3) analogues has not been reported.

OBJECTIVES

To investigate whether maxacalcitol, one of the active vitamin D(3) analogues, has a comedolytic effect by using spontaneously comedogenic rhino mice.

METHODS

Rhino mice were treated topically with tretinoin and maxacalcitol once daily for 2 and 4 weeks, respectively. The dermal side of the epidermal sheet was observed to determine the size of the utricle. Haematoxylin and eosin-stained vertical sections were used to measure utricle diameter and density and to evaluate histological changes.

RESULTS

Maxacalcitol (25 microg g(-1)) and tretinoin (0.1%) significantly decreased the size and the diameter of the utricle after 1 week of treatment. However, maxacalcitol did not affect the density while tretinoin did have an effect. Histopathologically, maxacalcitol and tretinoin markedly induced epidermal hyperplasia accompanied by a minor accumulation of inflammatory cells in the dermis, with and without hypercornification, respectively.

CONCLUSIONS

These results indicate that maxacalcitol has a prominent effect on comedolysis and that its mechanism of action may be different from that of retinoids.

A case-control study of bronchial asthma associated with ulcerative colitis: role of airway microvascular permeability

BACKGROUND

Recent attention has been devoted to the respiratory manifestations that may be associated with diseases of distant organs. The most prevalent and distinctive pattern of respiratory involvement in ulcerative colitis (UC) is airway inflammation.

OBJECTIVE

This study was designed to examine the contribution of airway microvascular permeability to the pathophysiological association of asthma with UC.

METHODS

Sputum induction and methacholine provocation test were performed in 27 asthmatic patients (15 without UC and 12 with UC), nine patients with UC and 15 normal controls. Inflammatory indexes, vascular endothelial growth factor (VEGF) levels in induced sputum, airway vascular permeability index and exhaled nitric oxide (NO) levels were examined in all subjects.

RESULTS

The percentage of eosinophils and concentration of eosinophil cationic protein in induced sputum were similar in all four groups. Though exhaled NO levels were significantly higher in asthmatics with or without UC than in normal controls or UC patients, these levels were comparable in asthmatics with and without UC. VEGF levels in induced sputum and airway vascular permeability index were significantly higher in asthmatics without UC (VEGF: 1920 (990) pg/mL; airway vascular permeability index: 0.018 (0.008)) and asthmatics with UC (6570 (1000) pg/mL; 0.040 (0.006)) than in normal controls (950 (700) pg/mL; 0.009 (0.003)), whose levels were comparable to those of UC patients (900 (600) pg/mL; 0.011 (0.003)). In particular, these parameters were markedly increased in asthmatics with UC than in asthmatics without UC. VEGF level was significantly correlated with airway vascular permeability index in asthmatics with UC. Moreover, VEGF level and airway vascular permeability index was inversely correlated with degree of airway obstruction and airway hyper-reactivity to methacholine in these asthmatics.

CONCLUSION

Airway microvascular hyper-permeability induced by VEGF may have a profound effect on airway function and can explain the heightened airway hyper-responsiveness characteristic of asthma associated with UC.

[Acute myocardial infarction with left ventricular free wall rupture and papillary muscle rupture caused by infectious endocarditis]

Infectious endocarditis sometimes causes coronary embolism which induces acute myocardial infarction. A 59-year-old man was admitted to our hospital with a diagnosis of acute myocardial infarction accompanied by left ventricular free wall rupture and papillary muscle rupture. We perfomed mitral valve replacement combined with repair of left ventricular free wall rupture. The anterior mitral leaflet had perforation and vegetation, which suggested that acute myocardial infarction was caused by septic embolus originated from infectious endocarditis in this case.

Imbalance between vascular endothelial growth factor and endostatin in emphysema

Vascular endothelial growth factor (VEGF) stimulates endothelial cell proliferation, and endostatin directly antagonises the biological effects of VEGF. The maintenance of pulmonary endothelial cells is also thought to depend upon the local balance of VEGF and endostatin in the lung. Therefore, this study was designed to determine whether there is an imbalance between VEGF and endostatin levels in patients with pulmonary emphysema. VEGF and endostatin levels were simultaneously measured from 25 emphysema patients and 12 normal control subjects, and their correlation and balance in induced sputum was evaluated. VEGF levels in induced sputum were significantly lower in emphysema patients (854 +/- 307 pg x mL(-1)) than in normal controls (1,791 +/- 1,192 pg x mL(-1)). In contrast, there was no significant difference in endostatin levels among the two groups. Therefore, the ratio of VEGF to endostatin levels was markedly lower in emphysema patients (4.5 +/- 1.8) than in normal controls (8.1 +/- 2.6). Moreover, VEGF levels were correlated with endostatin levels in normal controls but not in emphysema patients. In addition, the ratio of VEGF to endostatin levels was correlated with forced expiratory volume in one second (FEV1), FEV1/forced vital capacity and carbon monoxide diffusing capacity of the lung in emphysema patients. The findings in this study suggest that there is an imbalance between vascular endothelial growth factor and endostatin levels in induced sputum from emphysema patients.

Effects of captopril administration on pulmonary haemodynamics and tissue oxygenation during exercise in ACE gene subtypes in patients with COPD: a preliminary study

BACKGROUND

We have previously shown that angiotensin converting enzyme (ACE) DD genotype is associated with exaggerated pulmonary hypertension and disturbance of tissue oxygenation during exercise in patients with chronic obstructive pulmonary disease (COPD). A pilot study was designed to examine the effects of captopril on these exercise related variables in COPD patients categorised according to ACE gene polymorphisms.

METHODS

Thirty six patients with COPD (II=13, ID=11, DD=12) received oral captopril (25 mg) or placebo in a randomised, double blind, crossover manner and underwent right heart catheterisation with exercise.

RESULTS

Mean pulmonary arterial pressure (mPAP), pulmonary vascular resistance (PVR), and lactate concentration after exercise with both placebo and captopril were higher in patients with the DD genotype than in those with the II or ID genotypes. In contrast, mixed venous oxygen tension (PvO(2)) was lower in patients with the DD genotype than in those with the other genotypes. Moreover, mPAP, PVR, and lactate concentration after exercise were lower in the captopril group than in the placebo group in patients with the II or ID genotype, but not in those with the DD genotype. PvO(2) after exercise was higher with captopril than with placebo in patients with the II genotype, but not in those with the other genotypes.

CONCLUSIONS

These findings suggest that pulmonary haemodynamic variables and state of tissue oxygenation during exercise are dependent on ACE genotypes, and that captopril administration effectively influences these exercise related variables. Although the sample size in this pilot study was limited, it is likely that the improvement in exercise related variables in COPD patients with the II genotype is relatively sensitive to captopril.

Increased levels of vascular endothelial growth factor in induced sputum in asthmatic patients

BACKGROUND

Vascular endothelial growth factor (VEGF) is highly expressed in the airway of asthmatic patients. As VEGF increases airway vascular permeability, consequent thickening of the airway wall mucosa may lead to narrowing of the airway lumen.

OBJECTIVE

We evaluated the relationship between VEGF levels in induced sputum and eosinophilic inflammatory profiles, and the degree of airway vascular permeability in asthmatic patients and we evaluated the effect of inhaled corticosteroids on VEGF levels in induced sputum.

METHODS

Induced sputum specimens were obtained from 28 glucocorticosteroids free asthmatics and 11 healthy control subjects. We examined VEGF levels and airway vascular permeability index in induced sputum. After the initial sputum induction, 21 asthmatics received 8-week inhaled beclomethasone dipropionate (BDP, 800 micro g/day) therapy, then sputum induction was repeated.

RESULTS

The VEGF levels in asthmatics were significantly higher than in healthy control subjects (P < 0.0001). The VEGF levels were negatively correlated with forced expiratory volume of 1 s (FEV1, % predicted, r = - 0.68, P < 0.001), the percentage of eosinophils (r = 0.51, P < 0.01) and ECP levels (r = 0.39, P < 0.05). Moreover, the VEGF levels were significantly correlated with airway vascular permeability index (r = 0.61, P < 0.001). After 8-week inhaled BDP therapy, the VEGF levels were significantly decreased compared to pretreatment levels (P < 0.0001) and the VEGF levels were significantly correlated with airway vascular permeability index even in post-treatment asthmatics (r = 0.62, P < 0.01).

CONCLUSION

The VEGF levels in induced sputum were increased in asthmatics and its levels were associated with degree of airway narrowing and airway vascular permeability. These findings provide strong evidence that VEGF may play an important role in the pathogenesis of bronchial asthma.

Imbalance between levels of nitrogen oxides and peroxynitrite inhibitory activity in chronic obstructive pulmonary disease

BACKGROUND

The prevalent theory concerning the pathogenesis of chronic obstructive pulmonary disease (COPD) is of an imbalance between oxidants and antioxidants in the lung. It has recently been reported that the production of peroxynitrite, an extremely potent oxidant, is increased in the airways of patients with COPD. A study was undertaken of the imbalance between the levels of nitrogen oxides and antioxidant activity against peroxynitrite in the airways of patients with COPD.

METHODS

Sputum induction was performed in 30 patients with COPD and 15 normal control subjects. Levels of nitrogen oxides, percentage of neutrophils, and interleukin 8 (IL-8) levels were measured in sputum samples, and peroxynitrite inhibitory activity was assayed by monitoring rhodamine formation.

RESULTS

Nitrite and nitrate levels in induced sputum were significantly higher in patients with COPD than in normal controls (949 (133) microM v 621 (89) microM, p<0.001). In contrast, peroxynitrite inhibitory activity in induced sputum was significantly lower in patients with COPD than in normal controls (47.4 (12.7)% v 92.9 (3.9)%, p<0.001). There was a negative correlation between nitrite and nitrate levels and peroxynitrite inhibitory activity in induced sputum (r=-0.775, p<0.001). Peroxynitrite inhibitory activity was also significantly correlated with forced expiratory volume in 1 second (FEV(1)) % predicted (r=0.539, p=0.004), FEV(1)/FVC (r=0.512, p=0.006), and carbon monoxide transfer factor (TLCO) (r=0.486, p=0.009). Moreover, there was a significant negative correlation between peroxynitrite inhibitory activity and the degree of neutrophilic inflammation (percentage of neutrophils: r=-0.754, p<0.001; IL-8 levels: r=-0.497, p=0.007).

CONCLUSIONS

Reduced peroxynitrite inhibitory activity and increased levels of nitrogen oxides are found in induced sputum from patients with COPD. An imbalance in nitrogen oxides and antioxidant defence may contribute to the pathogenesis of COPD.

Diffusion-weighted MRI of the cervical spinal cord using a single-shot fast spin-echo technique: findings in normal subjects and in myelomalacia

We have implemented a new diffusion-weighted MRI (DWI) sequence based on the single-shot fast spin-echo technique. We hypothesised that this would add information to conventional MRI for diagnosis of lesions of the cervical spinal cord. DWI was performed using a technique in which echo collection after the application of motion-probing gradients was done in the same manner as in the single-shot fast spin-echo technique. We first imaged six healthy volunteers to demonstrate the cervical spinal cord using the sequence. Then we applied the sequence to 12 patients with cervical myelomalacia due to chronic cord compression. The spinal cord was well seen in all subjects without the distortion associated with echo-planar DWI. In the patients, lesions appeared as areas of low- or isointense signal on DWI. Calculated apparent diffusion coefficients of the lesions (3.30+/-0.38x10(-3) mm(2)/s) were significantly higher than those of normal volunteers (2.26+/-0.08x10(-3) mm(2)/s). Increased diffusion in areas of cervical myelomalacia, suggesting irreversible damage, can be detected using this technique.

Involvement of vascular endothelial growth factor in exercise induced bronchoconstriction in asthmatic patients

BACKGROUND

There is evidence that the bronchial microcirculation has the potential to contribute to the pathophysiological mechanisms of exercise induced bronchoconstriction (EIB) in asthmatic subjects. Vascular endothelial growth factor (VEGF), which is highly expressed in asthmatic airways, increases vascular permeability. The relationship between VEGF levels in induced sputum and the severity of EIB in asthmatic subjects was studied.

METHODS

The concentration of VEGF in induced sputum was examined in 23 asthmatic subjects and 11 normal controls. The asthmatic subjects performed an exercise test and the % maximal fall in forced expiratory volume in 1 second (FEV(1)) was measured. Beclomethasone dipropionate (BDP) 400 micro g twice daily was administered to the asthmatic subjects for 8 weeks and the exercise test and sputum induction were repeated.

RESULTS

The concentration of VEGF in induced sputum was significantly higher in asthmatic subjects than in normal controls. There was a significant correlation between the concentration of VEGF and the % maximal fall in FEV(1) (r=0.826, p=0.0001) and between the concentration of VEGF and airway vascular permeability index (r=0.621, p=0.0037). After treatment with inhaled BDP there was a significant decrease in the concentration of VEGF in the asthmatic subjects (before treatment: 7051 (2361) pg/ml, after treatment: 4498 (2135) pg/ml, p<0.0001). The change in the concentration of VEGF was significantly correlated with the change in the % maximal fall in FEV(1) (r=0.463, p=0.031).

CONCLUSIONS

Excessive production of VEGF in asthmatic airways may contribute to the pathogenesis of EIB via increased airway vascular permeability.

Decreased peroxynitrite inhibitory activity in induced sputum in patients with bronchial asthma

BACKGROUND

The production of peroxynitrite, an extremely potent oxidant, is increased in inflammatory lung disease. It is therefore important to measure antioxidant activity against peroxynitrite in epithelial lining fluid to examine the physiological effects of peroxynitrite in the airways of patients with asthma. This study was designed to determine whether peroxynitrite inhibitory activity in induced sputum is correlated with clinical characteristics and airway inflammatory indices in asthmatic patients.

METHODS

Inflammatory indices were measured in induced sputum from 25 patients with asthma and 12 normal control subjects. Peroxynitrite inhibitory activity was also measured by monitoring rhodamine formation in sputum samples.

RESULTS

Peroxynitrite inhibitory activity in induced sputum was significantly lower in asthmatic patients (52.4 (24.5)%) than in normal control subjects (92.1 (3.9)%, p<0.0001). Its activity was significantly correlated with forced expiratory volume in 1 second (FEV(1)) % predicted (r=0.774, p<0.0001) and bronchial hyperreactivity to methacholine (r=0.464, p=0.023). There was a significant negative correlation between peroxynitrite inhibitory activity and the degree of eosinophilic airway inflammation (% eosinophils, r=-0.758, p<0.0001; eosinophil cationic protein, r=-0.780, p<0.0001).

CONCLUSIONS

Decreased peroxynitrite inhibitory activity occurs in induced sputum of asthmatic patients. Since even in patients with stable asthma the airway lining fluid lacks peroxynitrite inhibitory activity, large amounts of peroxynitrite, which are further increased during an acute asthma attack, would not be completely inactivated and asthmatic airways might have markedly increased susceptibility to peroxynitrite induced airway injury.

Successful surgical treatment of a ruptured abdominal aortic aneurysm without homologous blood transfusion in a Jehovah's Witness: report of a case

We report herein the case of a 47-year-old woman of the Jehovah's Witness faith in whom Y-grafting for a ruptured abdominal aortic aneurysm was successfully performed without a homologous blood transfusion. We used a Cell Saver (Haemonetics, Braintree, MA. USA) red cell salvaging device and an aortic occlusion balloon catheter, and performed gentle and minimal dissection during the operation. Postoperatively. the patient was kept heavily sedated and required hypothermic therapy for only 14h. We treated her severe anemia using conventional drugs, including iron and folic acid, and her hemoglobin increased smoothly. Although her hemoglobin level decreased to 2.8g/dl during the operation, her postoperative course was uneventful.
