[Aneurysms of the celiac trunk. Review of the literature. Personal deductions apropos of 2 cases].

Aneurysm of the celiac trunk is the rarest lesion of this type reported in the digestive arterial system. Two cases are reported and the 78 lesions of a similar nature documented in the literature reviewed. The etiology at the present time is mainly atheroma in the over 50' s and dysplasia of the elastic tissue in young subjects. Clinical diagnosis is difficult since symptomatic forms are the cause of errors and latent forms frequent (41 p. 100 of cases). Preoperative angiography must be a complete investigation and allows study of splanchnic vascularization and the presence of collaterals. When there are no contraindications, surgical treatment can prevent progression to rupture. After resection or reduction of the aneurysm revascularization may be envisaged but is not essential: --in the first case reported the failure of revascularization proved its inutility, --whereas failure in the second case led to severe hepatic and gallbladder complications. Successful results have been obtained in 90 p. 100 of 41 cases operated upon since the initial surgical treatment performed by Shumaker in 1958 [47].

[Thoracic outlet syndrome. Apropos of 112 cases: toward a more refined tactical approach].

A total of 112 operations were performed in 87 patients with a cervicobrachial syndrome, 25 with bilateral lesions, over a period of 8 years. Surgery was reserved for severe or complicated cases. Presenting signs were complex and intricated in 53 p. cent of cases, with neurological lesions predominating. Absence of radial pulse after 90 degrees abduction of the arm, present in 87 p. cent of patients, is not a specific diagnostic test as positive results are obtained in over one-third of a normal population. Electromyography confirmed clinical lesions of the brachial plexus in only one out of 8 cases. A more precise and more sensitive procedure for electromyographic exploration of the plexus was therefore established. Dynamic arteriography of the upper limbs was not conducted routinely (70 p. cent of cases), but was reserved for arterial, neuro-arterial, and arterial and venous forms. The axillary approach was used exclusively (94 times), between 1974 and 1980. However, the frequency of postoperative complications (10 p. cent), and the high level of poor or incomplete results (19.5 p. cent) led to the reestablishment of the supraclavicular route of approach. The latter is used preferentially in neurological forms (57 p. cent of cases in this series) in cases requiring correction of an arterial lesion (aneurysm, ulcerated plaque), or when a cervical rib or apophysomegalia of the 7th cervical vertebra is associated.

Persistent hypoglossal artery.

During embryological development, the hypoglossal artery serves as a transient anastomosis between the internal carotid artery and the vertebro-basilar system. This artery occasionally persists into adult life. Two cases of persistent hypoglossal artery we have recently encountered are reported here. The embryology, diagnosis and potential problems for carotid surgery are discussed.

Hydronephrosis after aortofemoral bypass graft. A prospective study.

This prospective study was designed to determine the frequency and natural history of hydroureteronephrosis (HUN) after placement of an aortobifemoral vascular graft. A total of 30 patients were evaluated by the study protocol, which included: pre and postoperative biological kidney function tests, preoperative and early postoperative (14th day) intravenous pyelograms and a late (mean 18th month) urologic examination by renal ultrasonic tomography. Four asymptomatic, early cases of HUN were observed in the 57 ureters examined (7%); all four complications regressed in less than 30 days. No cases of symptomatic early or late HUN were observed in this series. Asymptomatic early HUN was a frequent complication in our series (7%) but its benign course does not justify systematic screening. These asymptomatic complications contrast with the symptomatic cases of early or late HUN reported in the literature which necessitated urologic and vascular investigations.

Synchronous reconstruction for combined aortoiliac and femoropopliteal occlusive lesions. The role of proximal bypass.

Between January 1984 and December 1986, 31 patients underwent synchronous revascularization (SR) because of the serious clinical condition of a lower limb and presence of arteriographically visible lesions. Average follow-up was 30 months. Operative mortality was 10%. Two patient populations were identified: Group I (N = 13): patients who underwent ilio-femoral or aorto-femoral proximal revascularization (PR); Group II (N = 18): patients who had axillo-femoral PR. Group I patients were younger than those in Group II (64 yr versus 72 yr; p less than 0.01). An association of pre-operative risk factors (arterial hypertension; coronary, renal or respiratory insufficiency) was twice as frequent in Group II as in Group I (p less than 0.02). The rate of SR compared to PR alone was 15%. However, there was no statistically significant difference between Groups I and II. Comparison of the actuarial survival curves for patients ahd the patency rates of SR in Groups I and II failed to reveal any statistically significant differences. Axillo-femoral bypass can be used for PR when SR is necessary in high risk patients.

[Venous involvement in the thoracic outlet syndrome (apropos of 30 cases)].

This paper present 30 patients with subclavian venous compression caused by a thoracic outlet syndrome. 3 stages are differentiated: intermittent compression: 15 patients; acute occlusion: 5 patients; chronic occlusion: 10 patients. Every stage corresponds with a clinic and radiologic unit: venous claudication of the upper limb; phlebitis; post-phlebitis syndrome. 8/30 patients had a bilateral compression. 22/30 patients had an associated arterial compression. The hypertrophy of the subclavian muscle is the main etiology of the venous compression. The venography dynamic of the upper limb is the basic investigation. The resection of the first rib is the basic intervention, according to the technic of Roos. A venous thrombectomy was associated in 4 cases. A previous general thrombolysis was associated in one case.

[Deep venous thromboses in obstetrics. Apropos of 19 cases].

Between January 1974 and December 1984, 4 cases of deep venous thrombosis (DVT) during pregnancy and 15 cases in the post-partum period, have been reported. Their frequency reaches 1.5% of the deliveries. The most important encouraging circumstances are a past history of DVT and Caesarean section. The treatment is difficult. In light of the 18 cases reviewed, the surgical treatment gives the best results.

[Value of revascularization of the hypogastric artery in chronic vascular disorders of the lower limbs. Personal experience with 200 cases].

Physiopathological studies combined with clinical experience have stimulated renewed interest in the hypogastric artery, a true circulatory center for the lower limbs but also a "spare wheel" in case of failure of aortofemoral revascularization. For these reasons it is considered that as with the deep femoral arteries the direct reestablishment of the hypogastric arteries should be a desired objective. To support this opinion, results of 200 direct revascularizations of the internal iliac artery are reported. These were conducted during aorto-ilio-femoral restoration, and the technique is now well established: either thrombo-endarterectomy (41% of cases); prosthetic by-pass (51% of cases) or exceptionally reimplantation (8% of cases).

[Thrombophlebitis of the ovarian vein with a floating clot in the inferior vena cava].

The authors report two recent observations of thrombophlebitis of the right ovarian vein. The first occurred after a cesarotomy, due to a bigeminal pregnancy, and the second, after a breech delivery. The diagnosis was given when faced to a febrile syndrome and pains of the right flank and confirmed in both cases by an abdominal tomodensimetric examination. In both cases, an enlargement of the lower vena cava thrombosis was observed with a floating clot that reached the renal veins. Both patients underwent a surgery. The latter consisted in both cases in a thrombectomy of the lower vena cava as well as a ligature of the right ovarian vein. In both cases, the evolution was positive, thanks to a remote-control of the lower vena cava via tomodensimetry. This therapeutic procedure and other potential therapies were discussed.
