[Application of auto-expansible endoprostheses to arteries of the legs].

An endovascular support inserted percutaneously, may represent an attractive solution to prevent early obstructions and recurrent stenoses after angioplasty (ATP). 23 iliac lesions and 40 femoro-popliteal lesions, symptomatic in 55 patients, were treated with endoprostheses of the Wallstent type. For the iliac implantations, it concerned in one case a recurrence after endarterectomy, 13 cases of recurrent stenoses after ATP and 9 cases of immediate failure of the angioplasty. The mean length of the lesions under treatment was 8 cm (extreme values between 4 and 14 cm). For the femoro-opoliteal arteries, the implants concerned lesions ranging between 3 and 7 cm, in 75 p. cent of the cases, and lesions exceeding 7 cm in 25 p. cent of the cases. Three iliac thromboses and six femoro-popliteal thromboses were reported at the beginning of this study; on the contrary, no thrombosis is present in the last 18 patients treated with oral anticoagulants. The rate of recurrent stenosis is low (none at the iliac level and 10 p. cent at the femoro-popliteal level); in all other cases an excellent clinical result was obtained with a mean follow-up of 18 months.

[Emboligenic calcification of posterointernal chordae of the mitral valve. Apropos of a surgically treated case].

We report the case of a 74-year old man who experienced two transient cerebral ischaemic accidents at 24 days' interval, showing that the isolated calcifications on chordae of the mitral valve posterior leaflet responsible for these accidents were exceptionally malformed. Two-dimensional echocardiography was the key examination, as it revealed a left intraventricular mass beneath the smaller mitral valve leaflet. Having excluded other cardiac causes of cerebral ischaemic accident, and faced with the recurrent character of these accidents, we decided to operate. Surgery confirmed the diagnosis. It consisted of resection of the calcified and ulcerated mass, combined with repair of the smaller mitral valve leaflet. Isolated calcifications of the mitral valve chordae are an exceptional cause of embolic accidents of cardiac origin.

[Subungual glomus tumors. Apropos of 2 cases].

Glomus tumours are uncommon, though not exceptional, benign growths developed from the constituents of the "neuromyoarterial glomus" initially described by Masson. Two cases of subungual glomus tumours of the hand in middle-aged women are reported. In spite of characteristic symptoms, with paroxysmal episodes of pain triggered off by cold and the most minute traumas, and of the finding in both cases of a violine++ tumour under the nail, the condition was belatedly diagnosed (7 and 27 years respectively after the onset of symptoms). Diagnosis rested not so much on standard radiography, which showed erosion of the distal phalanx in both patients, as on arteriography of the hand which displayed a small vascular pool at the arterial stage. Tumoral excision was successful.

[Endocarditis on cardiac pacemaker endocavitary electrodes. Apropos of 7 cases].

The authors report 7 cases of endocarditis on cardiac pacing catheters observed out of a total of 2 950 primary implantations and 1 600 pacemaker replacements. This is a rare condition (0.15%) but carries a poor prognosis as it usually occurs in elderly patients and demands aggressive management. The presence of multiple pacing catheters and surgical contamination due to manipulation of the pulse generator (reimplantation, pacemaker replacement) are predisposing factors. The infecting organism in these cases was a staphylococcus. One case of metastatic infection was also observed (acinetobacter). Ablation of the septic endocarditic material under effective, prolonged, double antibiotherapy is essential. Recently implanted electrodes were withdrawn by simple traction in 2 cases. This manoeuvre was attempted initially in all cases but stopped when chest pain or runs of ventricular extrasystoles occurred. Open heart explantation of pacing electrodes adherent to the ventricular apex was performed in 5 patients. Cardiopulmonary bypass without cardiac standstill enabled dissection of the fibrous rings surrounding the catheter after purging the blood from the atrial and ventricular cavities. In one patient, associated tricuspid valve endocarditis was found and valvular replacement was performed with a bioprosthesis. Endocardial pacing was replaced by epicardial pacing in patients with permanent AV block. The prognosis of this condition is poor; there were 2 deaths in this series of 7 patients.

[Thrombosis of the superior vena cava disclosing Behçet's disease].

The authors report the case of a 29 year old North African patient with Behçet's disease presenting with sudden thrombosis of the superior vena cava. Venous disorders are the fourth major sign of this disease. Although superficial thrombophlebitis is a common presenting sign, caval thrombosis is rare and usually occurs after several years' evolution. Superior vena caval thrombosis may be life threatening due to complications such as pulmonary embolism and haemoptysis. The anatomical substrate of this form of vascular disease is the same as that of the other visceral lesions of Behçet's disease: predominantly venous vasculitis with perivascularitis and secondary thrombosis. The pathogenesis of this thrombotic diathesis is discussed.

[Aorto-iliocaval fistula caused by rupture of an aneurysm. Apropos of 3 cases].

Three cases of aorto-iliocaval fistula are reported. Two cases were diagnosed during operation, an emergency laparotomy being indicated by the picture of hemodynamic shock unimproved by intravenous fluids, and without reduction in number of circulating red cells, associated with a painful abdominal aorta aneurysm. Recovery occurred after surgical closure of fistula and grafting of the aneurysm. In one case a caval stenosis required the insertion of a prophylactic subrenal clip. The third case was original in that a paradoxical pulmonary embolus developed in a patient with a primary left iliac aneurysm complicated by phlebitis. The hemodynamic state was such that a first stage operation. allowed insertion of a Greenfield's filter by the jugular route. Arteriography confirmed the diagnosis of a fistula and surgery was successful. Possible clinical manifestations of aortocaval fistula and surgical therapeutic measures are discussed.

[Valve replacement associated with aorto-coronary bypass in ischemic mitral insufficiency].

26 cases of ischaemic mitral regurgitation (MR) were treated by combined surgery: mitral valve replacement (MVR) and coronary bypass grafting (CBG). This type of operation is not common (1.3 p. 100 of all operations) and is usually reserved for men (21 cases) of middle age (average 59 years). A half of the cases had suffered previous myocardial infarction (MI), an average 5 months before surgery (range 20 days to 2 years). The other half had severe angina or ECG changes of myocardial ischaemia. 23 patients were in Class IV (15 patients) or Class III (8 patients) of the NYHA classification. 6 of the cases required intraaortic balloon pumping. Mitral regurgitation was severe () in half of the cases with a raised pulmonary capillary (mean V wave = 52 mmHg) and systolic pulmonary artery pressures (mean = 47 mmHg: exceeding 60 mmHg in 7 cases). The coronary lesions were severe in 18 patients (12 cases of double and 6 of triple vessel disease including 2 cases of left main stem stenosis). Ruptured chordae were found in 11 cases and papillary muscle necrosis in 4 cases. Surgery comprised MVR with 12 bioprostheses and 14 mechanical prostheses. 33 CBG were performed (anterior wall: 15 cases, posterior wall: 11 cases). In addition, one tricuspid annuloplasty and 3 ventricular aneurysmectomies were carried out. The hospital mortality was 15.4 p. 100. The main causes of morbidity were low output states and postoperative MI (2 cases).(ABSTRACT TRUNCATED AT 250 WORDS)

[Atypical compression of the humeral axial artery treated by surgical arteriolysis].

A 28-year-old man with atypical humeral artery compression presented clinical signs and results of Doppler tests suggestive of a cervicothoracic outlet syndrome: dysesthesie disorders and pain in left upper limb on active abduction. Murmurs over the vascular pathways were not elicited on clinical examination. Pulses were palpable in the upper limbs at rest but were abolished during abduction and external rotation. Data were confirmed by velocimetric studies, and dynamic arteriography showed absence of compression at the cervicothoracic outlet but its presence at the humeral head level. Axillohumeral surgical exploration provided evidence of compression of the nerve-vessel bundle, which was stretched within its sheath over the head of humerus. Incision of the fibrous sheath and freeing of the artery restored distal vascular pulsatility during abduction movements. This clinical pseudosyndrome of the cervicothoracic outlet appears to result from a rare cause of compression situated distal to this anatomic zone, and to respond to simple treatment.

[A comparative study of percutaneous transluminal angioplasty of the iliac and femoropopliteal arteries in arterial disease of the lower extremities].

The authors compared the anatomo-radiologic data from a series of 100 consecutive percutaneous transluminal angioplasties (PTA), as well as the immediate and long-term results as a function of the level of the lesion--iliac or femoropopliteal. Proximal to the thigh, there were 57 PTAs, 36 of the common iliac and 21 of the external iliac. In the lower thigh, there were 43 PTAs, 9 of the upper part of the popliteal artery and 34 of the external femoral artery. Percutaneous transluminal angioplasty of the common iliac lesion was dominant in patients under 60 years of age (p less than 0.05). At the iliac level, 89% of the patients had severe claudication; at the femoropopliteal level, 39% had trophic problems. The "dominant" or "accessory" character of the lesion did not modify the indication for the procedure, regardless of the level. Segmental thrombosis accounted for 44.2% of the femoropopliteal PTA indications, compared with 7% at the iliac level (p less than 0.04). The failure rate was less at the iliac than at the femoropopliteal level. Follow-up was available for 86.6% of the patients for an average of 22 months. The systolic indices at the thigh after iliac PTA and at the ankle after femoropopliteal PTA were significantly increased (p less than 0.01). At the femoropopliteal level, 74% of the patients were totally asymptomatic. There was one failure (3.8%); amputation at thigh level was carried out 12 months after the PTA. At the iliac level, improvement was observed in 91% of the patients and 70% became asymptomatic. The overall success rate (clinical patency and improvement) was 92% +/- 0.09%, based on the life-table method.

[Percutaneous transluminal angioplasty in chronic arteriopathies of the lower limbs. Immediate anatomo-radiological results and functional outcome].

The immediate anatomo-radiological results and functional outcome of a continuous series of 100 percutaneous transluminal angioplasties (PTA) in patients with chronic obliterative arterial disease of the lower limbs are reported. In 8 out of 10 cases, the patients had no previous surgical history. The iliac axis was more commonly affected than the infracrural arteries (57% compared to 43%). The indication of choice was the Leriche stage II (73%). The arterial lesion was responsible for the ischaemic pathology in 2 out of 3 cases. There was a higher incidence of preocclusive lesions (46%) than thromboses to be recanalised (23%) or significant stenoses (23%). The anatomo-radiological results were satisfactory in 80% of cases: a normal calibre was restored in 31% and stenosis was reduced to non-significant levels in 49% of cases. The morbidity associated with this technique was 7%: inability to dilate or thrombosis of the vessel. In 7 cases, failure was due to inability to pass the catheter across the stenotic lesion. Complementary surgical treatment was carried out on "accessory" arterial lesions in 33 cases; 32 sympathectomies for distal lower limb lesions and I femoro-popliteal bypass after iliac PTA. A total of 86.6% of PTA were followed up for an average of 22 months; 72% were totally asymptomatic; 21 were classified as stage II with improvement of their walking limits. The 3 year success rate was 0.92 +/- 0.1. Arterial surgery was necessary in 5.6% of cases for persistent severe intermittent claudication.(ABSTRACT TRUNCATED AT 250 WORDS)
