Bronchogenic cysts arise from an abnormal budding of the ventral diverticulum of the foregut or the tracheobronchial tree during embryogenesis. Pericardial location of these cysts is very rare. We describe a case of a young asymptomatic woman with an intrapericardial cystic mass compressing the right heart. Because of severe adhesions of the mass to the ascending aorta and to the right coronary artery, these structures were injured during surgical resection requiring the replacement of the ascending aorta and a coronary artery by-pass graft. Only the histopathologic findings provided the final diagnosis. [less ▲]

Background: This series aims to prove the positive impact of laparoscopic approach in aortofemoral bypass grafting. Methods : It concerns a retrospective non randomized study comparing 58 consecutive patients treated with laparoscopic procedure (n = 30) and with a standard open procedure (n = 28) in a single center. The different operating times, the complications and the follow-up of these two groups are compared Results : The demographics and angiographic data of the two groups were comparable. Operating time was longer in the laparoscopic group. However, we noticed a significant shorter hospitalisation stay (p < 0.0001) after the laparoscopic procedure with a mean 5.1 days. There was no significant difference of morbidity. Conclusion : We suggest that the trans-peritoneal approach is the best way in laparoscopic procedure in term of exposure and ergonomics. Laparoscopic aortofemoral bypass grafting is feasible, safe and effective. Shortening of operating time is observed as surgeon's experience grows. [less ▲]

OBJECTIVES: in patients with vascular prosthesis infection, to compare surgical outcome and long-term results of cryopreserved allograft implantations to conventional surgery. DESIGN: retrospective study. MATERIAL AND METHODS: two asynchronous series of 44 [series I: 1980-1994; 8 patients with aortoenteric fistula (AEF)] and 22 (series II: 1994-1997; 4 patients with AEF) patients were treated for prosthesis infection. All patients had prosthesis excision. In series I, there were 4 in situ reparations, 26 extra-anatomic bypass, 13 excision only, and one death at laparotomy. In series II, in situ cryopreserved allografts were implanted in all patients. RESULTS: operative mortality was 16% in series I and 13.6% in series II. For AEF patients, mortality was 37% in series I and 50% in series II. Among hospital survivors, infection-related late mortality was 13.5% in series I and 5% in series II. For AEF patients, late mortality was 20% in series I and 50% in series II. Incidence of reoperations was 54% in series I and 10.5% in series II (p<0.01). Hospital stay was 47.2+/-26.4 days in series I and 16.6+/-11.5 days in series II (p<0.001). CONCLUSIONS: compared to conventional treatment, incidence of reoperations and length of hospital stay are significantly decreased after cryopreserved allograft implantation. However, closure of aortic stump and extra-anatomic bypass gives better results for patients with AEF. [less ▲]

The routine use of arterial grafts in coronary surgery is facilitated by peroperative adjunction of antispasmodic drug to reduce the event of spasm. Diltiazem has been favoured in most clinical studies devoted to the radial artery graft. The aim of this study was to assess the efficacy of a spasm preventing protocol associating hydrostatic dilation of the graft with a diluted solution of papaverine and nicardipine infusion, starting preoperatively and continued postoperatively in i.v. and per os forms. Between September 1996 and March 1997, a consecutive series of 50 patients underwent myocardial revascularization using the radial artery. The radial artery was prepared by hydrostatic dilation with papaverine (1%) and nicardipine was administrated at 0.25 microgram/kg/min and titrated according to the arterial systemic pressure. Operative mortality was 4% (sepsis). There was no evidence of perioperative MI nor hypoperfusion syndrome. Mean CKMB level at 18 hours was 36 micrograms/l. No ischaemic anomalies of the ECG were detected. Angiography performed in the last 20 patients showed a 98% (51/52) permeability rate for all graft; 19/20 radial grafts (95%) were patent. One radial graft presented a 50% stenosis at the proximal anastomosis, and another a moderate spasm (40%) in the middle part of the conduit. This study confirms that the radial artery conduit can be used with satisfactory results for routine coronary artery bypass. The use of nicardipine allows the control the vasoreactivity of the radial graft without totally obviating at least angiographic spasm. This drug is easy to titrate, and well tolerated in association to beta-blockers in the routine perioperative management of the coronary patients. [less ▲]

Chronic rupture of abdominal aortic aneurysm (AAA) resulting in unusual clinical manifestations can occur if the resistance of structures surrounding the aorta is sufficient to contain hemorrhage. In this report, we describe five cases of chronic ruptured AAA in which the presenting feature was crural neuropathy. All patients were male with a mean age of 74 +/- 1.8 years. At the time of presentation, crural neuropathy had been ongoing for 3 to 9 weeks. In three cases, AAA was not initially suspected because an inadequate clinical examination was performed (not in the vascular surgery department) and because of the small diameter of the aorta in relation to the patient's morphology. Two patients had one episode of hypotension that was wrongly attributed to vagal attack. Abdominal CT scanning was always diagnostic of chronic rupture. In two cases, rupture was associated with erosion of the body of one or more vertebrae and laboratory evidence of inflammation, i.e., increase in sedimentation rate and fibrinogen level. The mean diameter of the AAA was 7.1 +/- 0.9 cm (range 5-10 cm). All patients underwent midline laparotomy, which was performed under emergency conditions in two cases, under semi-emergency conditions in one case, and electively in two cases. Perforation was consistently located on the posterolateral wall of the aorta and varied from 1 to 3 cm in length. Repair was performed using an aortobifemoral prosthesis in four cases, and a straight tube in one case. The patient who underwent emergency surgery died 4 days after the procedure. The remaining four patients recovered uneventfully and were discharged after 10 days. In the elderly, ruptured AAA should be included in the differential diagnosis of crural neuropathy. An episode of hypotension, regardless of its duration, in an elderly patient should be given serious consideration as a possible sign of ruptured AAA with ongoing retroperitoneal hemorrhage.

A typical appearance of IAH was evidenced by CT and TEE in a 56-year-old hypertensive female suspected of developping classical acute aortic dissection (AAD). Further examination with MRI and aortography showed unequivocally the presence of an intimal tear in the aortic arch. This coexistence of intimal tear has never been evidenced preoperatively in patients with IAH. This observation demonstrates at the outset that IAH is part of the spectrum of AAD. [less ▲]

From 1983 to 1990, 65 axillobifemoral and 20 axillofemoral bypasses have been performed in 85 patients (77 men and 8 women), with a mean age of 69 +/- 9 years. Indications for surgery were: severe aortoiliac occlusive disease (87%), sepsis of previous aortoiliac prosthesis, abdominal aorta aneurysm. Anatomic bypass was precluded for general (81%) or local (19%) conditions. In the last group, 9 patients have had previous laparotomy. Four patients presented with aortoenteric fistulas. Eighteen patients were operated on in emergency. The operative mortality was 12%, with 50% cardiac related deaths. Early primary patency was 98%. Early secondary patency was 100%. The mean follow-up is 28 +/- 15 months. The 3 years survival is 77%. The cumulative patency rates at 1 and 3 years are 89% and 76% respectively. Although axillobifemoral bypasses achieve poor long-term results when compared with aortoiliac bypasses, they can be considered in high risk patients. In this group of patients, the cumulative patency rate and the survival curves tend to be parallel. [less ▲]

Although rare, left atrial myxoma is an entity from anatomopathological and clinical aspects. Seven cases of left atrial myxoma operated on the last ten years were reviewed. We also report a rare presentation of right atrial myxoma, where the tumor was responsible of a dramatic hemodynamic shock due to right ventricular inflow obstruction. Six patients were female, with a mean age of 53 years. All but one consulted for exertional dyspnea of recent onset. Two patients with left atrial myxoma and the patient with right atrial myxoma had experienced embolism. Five patients had systemic symptoms. Echocardiography was the most performant diagnostic procedure. All but the patient with right atrial myxoma were operated by the left atrial access. The mitral valve was replaced in two patients. The histological aspect of this benign tumor is illustrated but the lack of frank border between the tumor and the myocardium is emphasized. We conclude that surgical management is primordial. We give anatomopathological rationale for resection of implantation pedicle. The operative mortality was nul in this series of 8 patients; major improvement of cardiac status was constant. No recurrence has occurred during the follow-up period. [less ▲]

Between 1983 and 1988, thirteen patients (12 men and 1 women, average age 63 years) were operated in the acute phase of myocardial infarction for papillary muscle rupture (PMR). The rupture involved the posterior papillary muscle in 12 cases. The average left ventricular ejection fraction was 47 +/- 9 per cent (range 34 to 63%). Pulmonary capillary pressures ranged from 76 to 41 mmHg (average 35 mmHg). Eleven patients presented with acute pulmonary oedema and 7 had cardiogenic shock. Coronary arteriography showed triple vessel disease in 3 cases, double vessel disease in 7 cases and single vessel disease in 3 cases. Surgery was carried out on average 2.7 days after the rupture and 10 days after the initial infarct. In addition to mitral valve replacement (N = 13), 11 patients underwent a myocardial revascularisation procedure. The operative mortality was 15 per cent (N = 2). Papillary muscle rupture in the acute phase of myocardial infarction causes cardiac failure which is related more to the mechanical abnormality than to an alteration of left ventricular function. Considering the operative mortality and the natural history of PMR treated medically, the authors recommend early surgery as the only management which can improve the precarious haemodynamic status of patients with this complication.

Through a fourteen years retrospective study of all the patients treated at the State University of Liege, we have focused on the survival of 449 patients with, at least, a clinical stage 3 NSCLC disease (NORMS UICC). The whole study was divided in two periods (1972-1978, period 1, and 1979-1985, period 2) because, everything remaining nearly equal as far as the clinical material was concerned, period 2 was characterized by a different therapeutic attitude. Since 1979, the NSCLC stage 3's surgical indications have been widely extended. We have performed surgical resections in patients with NSCLC N2 disease because of positive homolateral mediastinal lymph nodes or with T3 disease. This led the NSCLC stage 3 resection rate to move from 26% in period 1 to 47% in period 2. We report here the effects of such a management on the short and long term survival and the stage 3 NSCLC global prognosis. We noted a modest significant increase in the NSCLC stage 3 global prognosis with a five year survival of 4% and 6% (period 1 and 2 respectively; P = 0.03). The 172 resected patients' outcome did not change (five year survival 11% (P1) and 12% (P2]. Although patients were not randomized, our results suggest that adjuvant therapy should not be added whenever the patient underwent a complete resection. On the other hand, it seems very useful indeed whenever the resection was partial. NSCLC patient at stage 3 who underwent a complete resection achieved a 37% five years survival. [less ▲]
