RESUMO
Imaging descriptions are lacking for vertebral artery variants reported in the anatomy literature. We report thus a variant of vertebral arteries discovered incidentally in a patient admitted for aortocoronary bypass. Doppler of the supra-aortic arches revealed the absence of cervical segments of both vertebral arteries. Transcranial doppler revealed the presence of intracranial segments of these arteries that continued in a normal basilar trunk. MR-angiography performed on a 3T machine confirmed the bilateral absence of cervical segments and the presence of normal intracranial segments arising from the occipital arteries, branches of the external carotid arteries. Embryologic analysis explains this variant by an involution of cervical segments and persistence of anastomoses between the external carotid system and the vertebrobasilar system that normally regresses during fetal life. This anastomosis enables irrigation of the intracranial vertebrobasilar system by the external carotid artery. The introduction of 3T MR-angiography has enabled better and more precise detection of vascular variants without invasive angiography.

INTRODUCTION: Thoracic outlet syndromes are expressed by various clinical manifestations. Treatment is mainly rehabilitation. We aimed to identify factors predicting long-term functional rehabilitation in patients with this treatment and recurrence of symptoms. PATIENTS AND METHODS: We performed a descriptive retrospective analysis of 84 patients who underwent rehabilitation for thoracic outlet syndrome as defined by Revel and colleagues. Data collection involved a questionnaire exploring personal information, risk factors for developing thoracic outlet syndrome, clinical signs, and x-ray results. Long-term results of treatment were evaluated by telephone questionnaire. Data analysis involved use of Stata 6 software. RESULTS: Univariate analysis: predictive factors of negative results with treatment were ligament hypermobility, sensitive disturbances at the time of diagnosis, and a positive Adson's test result. Predictive factors of positive results were absence of paresthesia at the end of the treatment, and a negative "bell sign" at the end of the treatment. Predictive factors of nonrecurring symptoms were age younger than 34, bilateral positive Adson test result, and need for a supplementary number of sessions. MULTIVARIATE ANALYSIS: predictive factors of positive results with treatment were absence of sensitive impairment at the time of diagnosis, compliance with home exercises, initial negative Adson's test result, absence of hypermobility, and absence of paresthesia at the end of treatment. Predictive factors of recurring symptoms were age younger than 34, the need for a supplementary number of sessions and bilateral positive Adson's test result. CONCLUSION: A larger number of subjects are needed to further explore the predictive factors of rehabilitation and recurring symptoms in thoracic outlet syndrome for better validity and significance.

BACKGROUND: Great saphenous vein is one of the most used grafts in cardiovascular surgery. There is little amount of data in the medical literature describing dimensions of this vein. This series describes dimensions of the great saphenous vein in a coronary population and their variations. PATIENTS AND METHODS: Retrospective series of patients admitted to the cardiovascular surgery department of Hotel-Dieu de France Hospital - Beirut, between January 2003 and June 2006 for elective coronary artery bypass grafting and having a preoperative Doppler ultrasound of the saphenous veins according to a standardized protocol. Great saphenous vein dimensions were analyzed with regard to patients' characteristics using multivariable analysis of variance. RESULTS: Four hundred and two subjects were included with a mean age 64.4+/-9.3 years and a mean body mass index 27.9+/-4.5 kg/m(2). Women presented 22.6% of the series. Great saphenous vein dimensions' variations according to gender were significant (Multivariate Pillay trace=0.001) below the knee. Dimensions' variations were also significant as function of body mass index (P=0.001) and body surface (P=0.001). Age and cardiovascular risk factors did not influence GSV diameters. CONCLUSION: This series allowed constructing reference tables of the great saphenous vein segmental diameters in patients admitted for coronary artery surgery. Female sex is associated with lower segmental diameters below the knee and body mass index and body surface are linearly associated with segmental diameters at all levels.

The incidence of postoperative atrial fibrillation in cardiac surgery is still high despite major advances in anesthetic, pharmacological and surgical techniques. Its precise mechanism is still totally unknown. Postoperative atrial fibrillation increases length of stay as well as hospital costs. Rate of postoperative atrial fibrillation spontaneous conversion is high. Several protocols have been developed for prevention and/or treatment of postoperative atrial fibrillation. Beta-blockers, amiodarone and atrial pacing reduce.atrial fibrillation incidence as compared to placebo. On the other hand, amiodarone and propafenone achieve a high conversion rate of installed postoperative atrial fibrillation. However, among many pharmacological options, the best treatment is still to be defined.

OBJECTIVE: The aim was to determine if neutrophils are activated and sequestered as they pass through postischaemic human myocardium. METHODS: The occurrence of neutrophil activation during the reperfusion of the ischaemic myocardium was investigated in 16 selected patients undergoing coronary artery bypass surgery. Neutrophils were counted and elastase and lactoferrin released into the plasma were measured simultaneously in myocardial venous blood and in peripheral venous blood, before aortic cross clamping (T0), and two (T1), 10 (T2), and 20 (T3) min after unclamping. RESULTS: At T0, no statistically significant difference was noted between peripheral and myocardial blood with respect to the three variables studied. Reperfusion was associated with a significantly lower neutrophil count in myocardial blood compared to peripheral blood (p < 0.001), suggesting that neutrophils were trapped within the myocardium during reperfusion. In addition, levels of elastase (T1, T2, and T3), and lactoferrin (T1) were significantly higher in myocardial blood as compared to peripheral blood (p < 0.001), suggesting that activated neutrophils released their granular content into the plasma milieu. CONCLUSION: We provide evidence consistent with local neutrophil activation during myocardial reperfusion in patients undergoing coronary artery bypass surgery, in addition to the well described systemic activation related to cardiopulmonary bypass.

Thoracic splenosis is the autotransplantation of splenic tissue into the thoracic cavity after thoracoabdominal trauma. We report a case of thoracic splenosis in a 35-year-old woman who had had a thoracoabdominal gunshot wound 12 years earlier. A review of the literature revealed 15 cases already reported. All patients had an asymptomatic thoracic lesion discovered on a plain chest film 9 to 32 years (mean 16) after the initial accident. In 13 cases an operation was necessary to establish the diagnosis. In two cases technetium 99m and indium 111 scans established the diagnosis.

Among 206 consecutive patients having undergone mitral valve repair with a prosthetic ring between 1972 and 1979 in our institution, the 195 patients (94.5%) who survived the operation were studied to assess the long-term function of this method of repair. Patients' ages ranged from 18 to 79 years (mean age 48.7 years). Mitral valve insufficiency was due to degenerative disease in 113 patients (58%), rheumatic disease in 74 (38%), ischemia and other causes in eight patients (4%). A total of 188 patients (9.7%) were in New York Heart Association class III or IV preoperatively and 94 (48%) had atrial fibrillation. The patients were divided into three functional groups: type I (normal leaflet motion), 35 patients (18%); type II (leaflet prolapse), 147 patients (75%); and type III (restricted leaflet motion), 13 patients (7%). The techniques included prosthetic ring annuloplasty (185 patients), leaflet resection (158 patients), chordal shortening (89 patients), leaflet mobilization (10 patients) and papillary muscle reimplantation (2 patients). Long-term follow-up was available in 189 patients (96.8%), for a rate of 2316 patients per year. The 15-year actuarial and valve-related survival rates were 72.4% and 82.8%, respectively. At 15 years, 93.9% of the patients were free from thromboembolism, 96.6% free from endocarditis, 95.6% free from anticoagulant-related hemorrhage, and 87.38% free from reoperation. Actuarial rate of freedom from reoperation was higher in the group with degenerative disease (92.7%) than in the group with rheumatic disease (76.12%). Among the 157 survivors, 117 (74%) were in New York Heart Association class I and class II and 105 (66%) were in sinus rhythm. Doppler echocardiographic studies showed normal ventricular contractility in 134 patients (84.5%), absence of mitral regurgitation in 112 (74%), trivial regurgitation in 27 (17%), and significant regurgitation in 4 patients (2.5%).

Preliminary experimental studies in our laboratory have shown that autologous pericardium treated with glutaraldehyde prevents late deterioration and calcification of the tissue. For this reason, glutaraldehyde-treated autologous pericardium has been used in a series of 64 patients who underwent operations for leaflet extension of the mitral valve between 1980 and 1989. Ages ranged from 2.5 to 60 years (mean 19 +/- 15). The causes of mitral valve insufficiency were rheumatic fever (69%), bacterial endocarditis (17%), congenital (8%), endomyocardial fibrosis (4.5%), and trauma (1.5%). The autologous tissue was fixed in a 0.62% glutaraldehyde solution for 15 minutes and rinsed in saline for an additional 15 minutes. Patching techniques varied depending on the site and the extent of the lesion. Associated mitral valve repair techniques (Carpentier's techniques) were mandatory in all patients. The period of follow-up extended from 6 months to 9 years (mean 3.1 +/- 2.5 years). There were no operative deaths in this series, and there was one late death (2%). In the six patients (12%) who underwent reoperation, there has been no case of calcification of the pericardial patch. Postoperative mitral valve function was assessed by bidimensional color Doppler echocardiographic techniques. Mitral valve insufficiency was trivial or absent in 80% of the patients. This experience permits us to conclude that leaflet extension is a simple and safe technique in valve reconstruction, allowing repair of mitral valves that otherwise would need to be replaced. It permits use of an adult-size prosthetic ring in children. Glutaraldehyde-treated autologous pericardium is the material of choice for this type of repair.

OBJECTIVE: The aim of this study was to assess the long-term results of use of the radial artery as a conduit for coronary artery bypass grafting. METHODS: After revival of the technique in 1989, the radial artery was used as a conduit in 910 patients undergoing coronary artery bypass grafting. A complete follow-up was obtained for the first 102 consecutive patients from 4 to 7 years after the operation (mean 5.27 +/- 1.30 years). Fifty-nine percent of the patients were receiving calcium-channel inhibitors. An electrocardiographic stress test was obtained for 51 patients, with no contraindications found. Routine follow-up angiography was performed in 50 cases, including those of all patients with symptoms. Thus 64 radial artery and 48 left internal thoracic artery grafts were followed up from 4 to 7 years after the operation (mean 5.6 +/- 1.40 years). RESULTS: The actuarial survival was 91.6% at 5 years, and the actuarial rate of freedom from angina was 88.7% at 5 years. Four patients underwent percutaneous transluminal angioplasty during the period of follow-up, and there were no reoperations for revision of the bypass. The electrocardiographic stress test showed negative results in 73% of cases, electrocardiographic changes alone in 21%, and clinically positive results in 6%. Angiography showed that the patency rate of the radial artery grafts was 83%. The patency rate of the left internal thoracic artery grafts (n = 47) was 91%. The difference in patency could be related to the implantation sites of the grafts, mainly the circumflex artery (51%) for the radial artery grafts and almost exclusively the left anterior descending artery (94%) for the left internal thoracic artery. CONCLUSION: The use of the radial artery for coronary bypass grafting provides excellent clinical and angiographic results at 5 years. Routine use of the radial artery in combination with the left internal thoracic artery can be recommended.

OBJECTIVE: Coronary artery and aortoiliac disease frequently coexist. In rare instances simultaneous procedures may be required. This study reports our experience with ascending aorta to bifemoral bypass. DESIGN: Prospective consecutive sample study. PATIENTS: Ten male patients who underwent concomitant aortoiliac and coronary revascularization with the ascending aorta as the source of inflow to the femoral arteries between 1989 and 1991. RESULTS: One hospital death was unrelated to the surgical technique. All survivors displayed an uneventful recovery and were free of symptoms. Follow-up was obtained in all nine cases, they all stayed asymptomatic in terms of coronary artery disease and peripheral vascular disease. Echo-doppler studies showed perfect patency of the aorto-femoral grafts in all cases. CONCLUSIONS: This study shows that the ascending aorta to bifemoral bypass constitutes an interesting alternative in selected cases mainly those with severe ischemia coronary and leg ischemia. It offers the following advantages: (1) it is easy to perform, (2) does not require an intraperitoneal procedure, (3) the graft's position behind the muscles of the abdominal wall is not compressible, (4) the ascending aorta is the source of inflow, and (5) it allows a shorter duration of hospital stay.

Forty-nine war casualties with penetrating cardiac wounds were treated at the Hôtel-Dieu de France University Hospital between April 1975 and December 1987. All the wounds were caused by high-velocity missiles. An aggressive approach was utilized. Emergency room thoracotomy was performed in 17 "lifeless" patients, 4 of whom survived. Twenty-seven of the 32 patients who were in stable enough condition to undergo initial repair in the operating room survived. Overall survival was 63% (31/49). No intracardiac injuries were diagnosed in survivors, and no cardiac reoperations were required. Careful analysis of the trajectory of the missile or missiles and a portable chest roentgenogram were the most important factors for diagnosing a penetrating wound to the heart and for predicting potential associated injuries.

The biatrial transseptal approach according to the Dubost technique provides an excellent exposure to the mitral valve. Over a 5-year period (1984 to 1989) we used this approach in 210 patients. We believe that this incision is indicated in the following situations: reoperation on the mitral valve and acute mitral insufficiency with little enlargement of the left atrium.

A new surgical technique for treating type A aortic dissections is described. It consists of the exclusive and extensive use of surgical glue without replacing a segment of the ascending aorta. Since 1984, 21 patients were operated on using this technique. No operative mortality occurred and one reoperation for redissection was required. The technique is simple and safe and yields excellent short-term and long-term results.

Recurrent aortic valve endocarditis is frequently associated with paravalvular ring abscess that destroys the annulus. In occasional cases, the degree of necrosis, destruction of the annulus, and the presence of intramyocardial abscesses make it impossible to seat a new prosthesis. Danielson reported initial success in treating such patients by translocating the aortic valve to the ascending aorta and placing vein grafts to the coronary arteries. We recently treated a 17-year-old patient suffering recurrent aortic valve endocarditis using Danielson's technique, which we modified by implanting the left main coronary artery directly into the conduit. We believe that in young patients this modification can offer a beneficial alternative.

Forty patients were operated on in the early phase of active endocarditis between 1980 and 1988. Indications for operation were heart failure (30 patients), severe valvular regurgitation (4), uncontrolled sepsis (2), septic emboli (3), and other (1 patient). Time between onset of endocarditis symptoms and operation ranged from 12 to 45 days (mean, 30 days). The aortic valve was involved in 3 patients; the mitral valve, in 28; both valves, in 7; and the tricuspid valve, in 2. There was no previous underlying valve pathology in 40%. Lesions found were cusp perforation (17 patients), annular abscess (4), vegetation (13), and chordal rupture (22). Positive blood cultures were found in 30 patients (75%). Bacterial findings were Streptococcus in 12 patients (30%), Staphylococcus in 15 (37.5%), gram-negative in 3 (7.5%), and unknown in 10 (25%). Criteria to perform valve repair were adequate antibiotic therapy for at least 1 week and large excision of all macroscopically involved tissues. In all cases, Carpentier's reconstructive techniques were used. Perioperative mortality was 2.5% (1 patient). Reoperation was necessary in 1 patient. Late mortality was 2.5% (1 patient). Repair was assessed either by angiography or by Doppler echocardiography before hospital discharge: 32 patients showed no regurgitation, whereas 7 had mild regurgitation (3 aortic, 4 mitral). Mean follow-up of 30 months was achieved in all survivors. There was no recurrence of endocarditis and no reoperation for valvular insufficiency. We conclude that valve repair in acute endocarditis is possible and effective in most instances.

BACKGROUND: During free internal mammary artery grafting, cardioplegia administration can be performed through the internal mammary artery. The present study examined whether cardioplegic solutions produce arterial graft constriction and functional endothelial damage. METHODS: Forty internal mammary artery segments from 10 patients were incubated in Krebs solution (n=10), University of Wisconsin solution (n=10), Broussais Hospital solution (n=10), or blood cardioplegia (n=10). RESULTS: There was a significant difference in sensitivity to norepinephrine between segments in Krebs solution and those in University of Wisconsin solution or Broussais Hospital solution but not segments in blood cardioplegia. There was a significant difference in relaxation to acetylcholine between segments in Krebs solution and those in the three other cardioplegic solutions and between those in blood cardioplegia and segments in University of Wisconsin solution or Broussais Hospital solution. There was no significant difference in relaxation to sodium nitroprusside between segments in any of the solutions. CONCLUSIONS: These experiments suggest that storage in the different cardioplegic solutions studied does not preserve the initial vasoreactivity of the internal mammary artery. However, blood cardioplegia appears to be less deleterious in regard to endothelial and myogenic vascular function.

Cardiac hemangiomas are rare benign vascular tumors of the heart. To date, 23 cases have been reported. Symptoms are usually due to compression of cardiac structures or obstruction of outflow tracts. Echocardiography usually directs the diagnosis toward a cardiac mass. Enhanced-contrast computed tomographic scan or magnetic resonance imaging establishes the diagnosis of hypervascularized cardiac tumor. Coronary arteriography establishes the diagnosis by showing the characteristic tumor blush. Surgical resection is done using cardiopulmonary bypass. Long-term outcome is favorable.

Ten patients were operated on within one hour to 3 months after percutaneous mitral dilation. Operative analysis of the lesions demonstrated hemopericardium (n = 3), acute mitral insufficiency (n = 7), left atrial thrombus (n = 2), and atrial septal defect (n = 3). A conservative treatment of the mitral valve lesion was performed in 6 patients. All patients had uneventful postoperative courses. The complications presented in this series were either due to technical error or occurred in patients with relative contraindications to percutaneous mitral dilation (calcified commissures).
