A 67-year-old man receiving treatment for choledocholithiasis was found to have an abdominal aortic aneurysm on CT. The maximum diameter of the aneurysm was 60mm, and the isthmus of a horseshoe kidney was also observed. A total of four renal arteries, two each on the right and left sides, was detected by angiography and helical CT. Two of four arteries bifurcated from the aneurysm. Laparotomy confirmed the presence of a fifth renal artery, which extended from the left common iliac artery to the isthmus. It was not difficult to free the isthmus from the aneurysm. A Y-shaped prosthesis was placed between the normal portion of the aorta and the common iliac arteries without severing the isthmus. The left renal artery arose from the aneurysm and was reconstructed with 6mm knitted Dacron. The right renal artery, which was located below the isthmus, was ligated. The absence of postoperative renal dysfunction confirmed the patency of the reconstructed renal artery. Eleven such cases have been reported in Japan, including the present case. In 5 cases, renal artery reconstruction was performed, and the isthmus was preserved in 8 cases. However, the sites of renal artery bifurcation were correctly detected preoperatively in only 3 of these patients. It appears that accurate preoperative imaging is very important, along with renal artery reconstruction.

The long-term efficacy of various treatments for intermittent claudication was studied to determine which regimen should be selected. Two hundred and nineteen patients with arteriosclerosis obliterans (ASO) and intermittent claudication of the extremities were divided into two groups based upon the type of treatment: 1) 170 patients who underwent arterial reconstruction and 2) 49 receiving conservative treatment. Fifty-five patients with Buerger's disease (TAO) with intermittent claudication were divided into three groups: 1) 17 patients who underwent arterial reconstruction, 2) 15 with lumbar sympathectomy, and 3) 23 receiving conservative treatment. The background factors of both disease groups were analyzed, and the changes in claudication, the quality of life, and the survival rate were followed up. Among ASO patients, the improvement of intermittent claudication was significantly better in the arterial reconstruction group (p<0.001) than in the conservative treatment group. The quality of life and 5-year surival rate were also superior in the arterial reconstruction group (p<0.01), and they were closely related to the improvement of intermittent claudication. On the other hand, there was no significant difference in any of these parameters between the three groups of TAO patients. This discrepancy in outcome was concluded to be due to differences in the background factors of the two diseases. Accordingly, the treatment for intermittent claudication should be discussed making a clear distinction between ASO and TAO. In conclusion, the treatment of choice for intermittent claudication is arterial reconstruction in ASO patients, whereas surgical treatment should only be considered for TAO patients when conservative therapy is ineffective.

The severity of mitral regurgitation (MR) and tricuspid regurgitation (TR) was evaluated semiquantitatively by Doppler color flow imaging. The maximum MR area/body surface area (MRA/BSA) correlated significantly to the severity of angiographyic changes (tau=0.897). The maximum TR area/body surface area (TRA/BSA) also correlated significantly to the severity in angiography (tau=0.874). The cutoff values were 0.5, 2, 4, and 8cm²/m² for MRA/BSA and 1, 2.5, 5, and 10cm²/m² for TRA/BSA. Fourteen children (mean age 4.2 years) underwent repair of partial atrioventricular septal defects (P-AVSD) from 1985 to 1992. The cleft in the anterior leaflet was closed in the mitral valve; other procedures such as annuloplasty were not performed. They have been followed for periods from 7 months to 7 years and 5 months (mean 4 years); they were examined by echo cardiography and the Holter electrical cardiogram at the end of the period. MR had reduced to grade 0-II in all cases. No patients were given any medication, and all remained in NYHA Functional Class I. Paroxysmal supraventricular tachycardia developed in only one patient. We concluded that no annuloplasty in mitral valve is needed in children suffering from P-AVSD.

We present a rare case of stent graft infection. A 69-year-old man, who had undergone endovascular repair of an abdominal aortic aneurysm with an Inoue stent graft 5 years previously, was admitted with high-grade fever. An abscess around an abdominal aortic aneurysm was found on abdominal computed tomography (CT) and he was given a diagnosis of stent graft infection. The stent graft was removed and vascular reconstruction was performed using a Gelweave graft bonded with rifampicin. The graft was then covered with the greater omentum, and he was discharged on the 27th postoperative day.

Ulcer developed on the left leg of a 47-year-old man, in 1989, and phlebography showed deep vein thrombosis extending from the politeal to the common femoral vein. Subfascial ligation of the perforators achieved healing of the ulcers. In November 1991, at the age of 52 years the patient noticed a pulsatile mass on the right side of his neck. CT scanning showed a carotid artery aneurysm 4cm in diameter. Angiography indicated that the aneurysm was located at the bifurcation of the carotid artery. In February 1992, reconstructive surgery was performed with a Dacron graft, but an anterile abscess developed around the graft. In September 1992, the graft was removed and the carotid artery was ligated. Only seven cases of carotid aneurysm associated with Behçet's disease have previously been reported in Japan. Five of them underwent reconstructive surgery and two of them underwent carotid ligation due to complications. Because of the clinical course of Behçet's disease, carotid aneurysmectomy without reconstructive surgery may be the procedure of choice.

Advanced cancer patients experience stress and are at risk for developing psychological problems. Early diagnosis and suitable intervention are very important for their quality of life and compliance with chemotherapy. The Hospital Anxiety and Depression Scale (HADS) is one of the most commonly used mood scales; however, HADS has not been validated for use with cancer patients undergoing chemotherapy. The purpose of this study was to validate HADS as a screening tool for psychological distress among cancer patients undergoing chemotherapy. We also identified possible factors contributing to psychological distress and explored the development of original screening tools. Fifty subjects agreed to complete HADS and consult with psychiatric specialists. Possible contributing factors to psychological distress were identified by HADS and logistic regression analysis. The mean score for patients with psychological distress was 20.0 ± 8.93, and for patients without distress was 9.67 ± 6.11; scores for patients with psychological distress were significantly higher. The optimal cutoff point of psychological distress appeared to be 17. This cutoff point was associated with 72.7% sensitivity and 82.1% specificity. The factor “recurrent cancer” (p=0.043) had an odds ratio of 7.24 (1.21-61.2). We verified that HADS is a useful screening tool for cancer patients undergoing chemotherapy. The factor “recurrent cancer” was shown to contribute to psychological distress. Palliat Care Res 2011; 6(2): 150-157

Purpose: Escitalopram has been inadequately evaluated in cancer patients. Here, we report two patients with advanced cancer who benefited from escitalopram for depression. Case 1: A man aged in his 50s had postoperative recurrence of rectal cancer. He was diagnosed with a major depressive episode according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR). The score of the Hamilton Rating Scale for Depression (HAMD-17) was 20 points. He began treatment with 10 mg/day of escitalopram. His symptoms began to improve at about 14 days, and the HAMD-17 score was 4 points at 23 days, suggesting a marked improvement. Case 2: A woman aged in her 50s had cancer of the external auditory canal. She was diagnosed with a major depressive episode according to DSM-IV-TR. The score of HAMD-17 was 26 points. She began treatment with 10 mg/day of escitalopram. Her symptoms began to improve at 15 days, and the HAMD-17 score at 28 days was 13 points, suggesting a marked improvement. In both cases, serious side effects, clear exacerbation of depression, and withdrawal syndrome due to acute drug deprivation associated with worsening of the symptoms were not noted. Conclusion: Escitalopram is considered a useful drug for depression in patients with advanced cancer.

Ischemic mitral regurgitation (IMR) is a serious and increasingly common clinical disorder, but at present, the relationship between left ventricular shape and IMR is not completely understood. Thirty patients with moderate or severe IMR who underwent mitral valve surgery combined with coronary artery bypass grafting were studied retrospectively. Left ventricular shape, left ventricular regional wall motion, hemodynamic index, condition of the coronary artery, severity of IMR and long term results were assessed using ventriculography and angiography. Left ventricular shape at end diastole and end systole were quantified based upon the ratio of the major-to-minor axis and the sphericity index. Hospital mortality rate was 13.3%, 5 years survival rates were 10.5%, and 5-year rate of freedom from congestive heart failure (CHF) were 7.8%. Significant difference between cardiac deaths (n=11) and survivors (n=19) included requiring intensive care admission, requiring intra-aortic balloon pumping, recurrent myocardial infarction, the ratio of the major-minor axis at end diastole, the sphericity index at diastole, and the sphericity index at end systole. Multivariable regression analyses were performed with the Cox proportional hazards model. Significant determinants of survival were the sphericity index at end systole and LV regional wall motion at the site of the anterobasal segment or apex. These findings indicate that the shape of the LV and LV regional wall motion in IMR may be important determinants of prognosis and suggest that surgical attention to shape may be helpful for mitral valve surgery.

A retrospective review was performed on 43 patients on hemodialysis undergoing valve surgery between May 1999 and August 2004. Ages ranged from 36 to 80 years (mean, 63.8 years). Twenty aortic, 9 mitral, 8 aortic and mitral and 6 valvuloplasties were performed. Twenty-three aortic mechanical valves, 5 aortic bioprosthetic valves, 13 mitral mechanical valves and 4 mitral bioprosthetic valves were implanted. Twenty-five of the 28 aortic valve replacement were hypoplasia of the aortic valve ring. There were 3 hospital deaths (heart failure, pneumonia and sepsis). There were 10 late deaths (2 heart failure, 2 pneumonia, wound infection, cerebral infarction, 2 cancer, arteriosclerosis obliterans and unknown death). Survival at 1, 3 and 5 years was 81%, 74% and 47%. There were three documented major bleedings or thromboembolisms in the 29 patients with mechanical valves (10%) and none in the 9 patients with bioprosthetic valves (0% no significance). Three reoperations were performed for premature degeneration of bioprosthetic valve (19, 24 and 50 months) due to accelerated calcification. These results demonstrate that the prosthetic valve-related major bleedings and strokes in hemodialysis patients are similar for both mechanical and bioprosthetic valves, and that bioprosthetic valves will undergo premature degeneration. Therefore, preference should be given to mechanical valve prostheses in hemodialysis patients.
