Transesophageal echocardiography diagnosis of tricuspid obstruction by a vena cava tumour.

PURPOSE: To present the anesthetic management for excision of a primary tumour of the inferior vena cava. CLINICAL FEATURES: Resection of a primary tumour of the inferior vena cava without extension to the right atrium was scheduled without extra-corporeal circulation (ECC). The operation consisted of tumour excision with transtumoral clamping. During the immediate postoperative period, tricuspid obstruction was suspected when a "cannon a wave" was recorded from the right atrial pressure curve. Transesophageal echocardiography confirmed the diagnosis of tumour obstruction of the tricuspid valve. CONCLUSION: Tricuspid obstruction due to postoperative mobilization of a primary tumour of the inferior vena cava was diagnosed by transesophageal echocardiography. Perioperative management particularities of the primary tumour of the vena cava are discussed.

[What is the place of conventional radiology in the exploration of esophageal dyskinesia and hiatal hernia?].

Esophageal dyskinesias are due to various aetiologies and sometimes present with marked clinical symptoms. The barium swallow remains the preferred first-line examination. Upper GI endoscopy and manometry are useful to confirm the functional nature and eliminate any concomitant or secondary mucosal lesions of these motor disorders. The clinical signs of hiatus hernia are essentially due to complications related to gastro-esophageal reflux. They can be asymptomatic or may present in the form of atypical, sometimes extra-gastrointestinal, symptoms. Although conventional radiology allows the diagnosis of hiatus hernia by specifying the type, the morphology and the anatomical relations, it may fail to detect the consequences of gastro-esophageal reflux, especially ulcerated lesions. Upper gastrointestinal endoscopy appears to be the first-line examination of choice for the diagnosis of hiatus hernia. Barium swallow is useful in cases of failure of endoscopy and in the context of preoperative assessment, as these two investigations are often complementary.

[Megaesophagus].

Although it was first described a long time ago, the pathophysiology of megaesophagus, a primary esophageal motor disorder due to an abnormality of the esophageal sphincter reflex ("achalasia"), remains poorly understood. Our paper shows that it may also be missed clinically for a long time, sometimes for psychological reasons.

[Study of the salivary glands in 1990].

Radiologic examination of the salivary glands can provide clinically useful information that may help to establish the diagnosis and indicate appropriate therapy. US and conventional sialography remain the standard methods of examination for inflammatory diseases and superficial parotid masses. However, CT and MR have allowed a new means of examination of parotid lesions, or of lesions around the parotid gland. MR appears to be the procedure of choice to investigate adenoid cystic carcinoma, recurrence and tumors expanding into the pterygopharyngal space or the sub-tonsillar space. Stenon duct endoscopy is a new imaging and therapeutic procedure to be introduced into the therapeutic strategy in these patients.

[Superior vena cava syndrome of rare aetiology (author's transl)].

The case of malformation of the subclavian artery (arteria lusoria) reported here is of interest not only because of its rarity but also the diagnostic problems which it posed and its unusual clinical presentation -- haemoptysis. This case report is completed by a review of the literature, which is restricted concerning this subject.
