Venous involvement by follicular carcinoma of the thyroid gland.

Involvement of the great veins by thyroid neoplasms is a rare event: to date 9 cases have been reported and only 2 of them have been surgically treated. The authors describe a case of follicular thyroid carcinoma involving the proximal tract of the left innominate vein at its confluence with the superior vena cava: a neoplastic bud was protruding into the lumen, but the endothelial lining appeared to be perfectly preserved. Full radicality was obtained by a major vascular procedure.

[Leiomyosarcoma of the inferior vena cava].

Leiomyosarcoma is a rare tumor of soft tissues. The inferior vena cava is affected infrequently, a literature review showing only 66 cases reported previously, 29 of these patients undergoing radical surgery. The case described was diagnosed during operation for gallstones, and the lesion was excised radically using an original technique.

Surgical approach to renal cell carcinoma extending into the right atrium through the inferior vena cava.

Successful management of a patient with an intracardiac tumor thrombus of renal carcinoma is described. This case and a few others in the literature have led us to consider the clinical signs of cavo-atrial obstruction, frequently silent and unspecific; the diagnostic methodology, especially based upon CAT scan and cavography, and the type of surgery and surgical technique called for, especially as regards the approach and the possible use of extracorporeal circulation (ECC).

Clinical staging of rectal cancer. Results of a prospective continuing study.

78 patients with rectal adenocarcinoma were studied with a diagnostic protocol in order to obtain a TNM clinical stage in the preoperative period. Each patient underwent digital rectal examination, proctoscopy, double contrast barium enema, pelvic CT scan, liver ultrasound and chest x-ray. The degree of infiltration of the rectal wall by the tumor and the presence or absence of node and liver metastases were evaluated.

[Left inferior vena cava and aneurysm of the abdominal aorta].

A case of isolated left-sided inferior vena cava, without situs inversus, in a patient with abdominal aortic aneurysm is reported. On the basis of a review of literature, the authors recall the incidence and the embryology of this anomaly, and analyze its surgical implications, with particular reference to abdominal aortic surgery.

[Cavoauricular thrombectomy under extracorporeal circulation and right superior lobectomy for paraneoplastic thrombosis in a case of lung cancer].

A patient with superior vena cava thrombosis from cancer of the right lung is described. The particular interest of this case resides in: The numerical scantiness of cases reported in the literature: 12 cases reviewed; The exceptional nature of the etiopathogenic mechanism: paraneoplastic thrombosis; and the more precise problems relating to the indication, technique and tactics with respect to surgery.

Effectiveness of intraoperative L.E.S. pressure measurement during Nissen-Rossetti fundoplication.

A study was made to evaluate the effectiveness of Lower Esophageal Sphincter Pressure (L.E.S.

[Surgical treatment of thromboses of the inferior vena cava].

Results of surgical treatment in 22 patients with inferior vena cava thrombosis from extension of femoro-iliac thrombosis are reviewed. Indications for the different types of operation and their technical modalities (thrombectomy through a femoral approach or by cavotomy, caval blockade by clip or Mobin Uddin's umbrella alone or combined with thrombectomy, arteriovenous fistula) are discussed in relation to the various pathological and clinical pictures observed.

Rupture of multiple hepatic adenoma and oral contraceptive use: a case report.

A 38-year-old woman was seen with a hemoperitoneum caused by rupture of a hepatic adenoma of the right lobe. The patient had been taking oral contraceptives for ten years, but discontinued their use three years previously. During the postoperative course a second adenoma of the contralateral lobe, not diagnosed at the first operation, ruptured.

Post-gravidic Budd-Chiari syndrome treated by mesocaval H-graft shunt.

A new case of Budd-Chiari syndrome following pregnancy is reported. The patient, shortly after her second normal delivery, showed clinical evidence of hepatic venous outflow impairment. The diagnosis of Budd-Chiari syndrome was supported by angiographic studies, computed tomography, liver scanning and histology.

[Hepaticoportal arteriovenous fistula: a case report, discussion of physiopathological and clinical problems, and review of the published literature (author's transl)].

A patient developed an arteriovenous aneurysm between the gastroduodenal and middle colon arteries and the main mesentericoportal vein, following gastroduodenal resection. This case is described, and patients with arteriovenous fistulae in the portal region reported in the published literature (179 cases) are reviewed. Etiological, pathological, and clinical aspects in relation to surgical treatment and according to the type and location of the lesion, are also discussed.

Prosthetic replacement of the superior vena cava after resection for malignant mediastinal tumour.

The authors describe a case of malignant neoplasm of the mediastinum affecting the S.V.C.
