Lateral distant view for improved accuracy in locating rectal tumors.

The lateral distant view of the rectum is proposed for more precise identification of sites of rectal tumors for preoperative planning and to increase the number of sphincter-saving operations. In a prospective study of 39 patients with rectal tumors, radiologic and rectoscopic measurements of tumor levels were compared with each other and with the actual tumor site. Radiologic measurement on the lateral distant view showed that tumors usually are located much higher (2-11 cm) than is suggested by rectoscopic evaluation. Unlike rectoscopy, the lateral distant view also can be used for measuring the length of the anal canal. This measurement is important for evaluating the distance between the tumor and the inner end of the anal canal and reflects the width of a possibly tumor-free margin. Sphincter-saving operations could be predicted much better by the lateral distant view than by rectoscopy.

[Subclavian-carotid artery transposition in the therapy of lesions of the proximal subclavian artery].

Employing an extrathoracic approach 10 patients were operated upon for 12 obstructive lesions of the subclavian arteries using carotid-subclavian anastomosis. The operation was indicated 3 times for the pathological entity of arterial stenosis embolizing into the vascular periphery, 3 times for claudication of the upper extremity and 4 times for cerebro-vascular insufficiency. Followed up to 31 months all anastomoses remained patent. All the complications were managed conservatively and were considered of minor importance.

[Preliminary experience with biological omental investment as a therapeutic procedure for infected lesions in vascular surgery].

Description of 8 patients, demonstrating deep infections following vascular reconstructive procedures. The classical method of treating these consists of removing all foreign material and circumventing the lesion by extra-anatomic bypass. A long extra-anatomic conduit needs a good run-off, therefore alternative methods of treatment are sometimes indicated, e.g. transposition of the omentum. In 8 instances healthy omentum was used to cover the infected conduit in order to preserve the reconstruction and to obtain healing of the wound. The procedure was successfully employed in 4 cases. Solitary infections healed without complications (3 patients). Out of 5 patients showing the catastrophic sequence of events - infection plus exsanguinating hemorrhage - only one was managed successfully.

Detection of intestinal diverticula by double-contrast small bowel enema: differentiation from other intestinal diverticula.

This report documents the roentgenographic diagnosis of diverticula in the jejunum and ileum. The experience has been gained from 7 Meckel's and 8 other diverticula shown by the small bowel enema in 400 patients. Diverticulum detection rate by this technique approaches the incidence in autopsy series. Differentiation between Meckel's, acquired, and pseudodiverticula by means of specific radiologic criteria is discussed.

Respiratory distress syndrome with new considerations.

To help maximize the salvage rate of patients with ARDS, radiologists must become active participants in a multidisciplinary team. A clear understanding of the nature of ARDS is a prerequisite. The authors briefly consider the pathogenesis of the syndrome and then discuss at length the usefulness of plain radiography and balloon occlusion pulmonary angiography in examining the patient with ARDS.

[Rare malposition of a subclavian vein catheter].

Deviation of a left subclavian vein catheter into the azygos vein occurred in a patient with cancer of the colon. On the p.a.-projection, the catheter seemed to be kinked in the vena cava. In the lateral view, the malposition in the azygos vein could be detected and was visualised by giving a bolus of contrast medium. By retracting the catheter under fluoroscopic control the proper position could be achieved. The importance of the lateral-view chest x-ray is discussed.

[Displacements and complications of superior vena cava catheter (author's transl)].

During a 16-months prospective study the frequency of displacements and complications of superior vena catheter has been investigated. The study showed, that the right jugular catheter has the lowest frequency of complications, and should be of primary choice. Pneumothoraces are rare with jugular vena catheters (0,05%), more frequently with subclavian catheters. Setting of superior vena catheter displacement in large veins is quite common. More important are catheter displacements in small veins, which are more frequent with jugular than with subclavian vena catheter (vena thoracica interna, vena pericardiacophrenica). Adequate X-ray control (high KV technic, sufficient amount of contrast medium) is necessary to recognize these complications. Correction of displaced catheter should be done under fluoroscopy. Serious complications s.e. tension pneumothorax and haematothorax are rare and should be treated surgically. In some cases no recognized extravasal catheterposition is followed by infusions into the pleural cavity or the mediastinum.
