Xeroradiography of tenomuscular traumatic pathologic conditions of the limbs.

Due to its intrinsic technical features xeroradiography is particularly suitable for the documentation of soft tissue abnormalities. Indications and advantages of the method in the posttraumatic alterations of the tenomuscular system of the limbs are discussed. Several examples of acute or chronic diseases are presented. The authors prefer this technique to the traditional films in view of the obtainable graphic results; a better demonstration of the tenomuscular structures is obtained. Often comparison with the contralateral side is necessary; the performance of "functional' xeroradiograms is essential, especially in smaller lesions. Xerography is a useful complement of clinical examinations for an early diagnosis of lesions, for detection of clinically doubtful lesions and for the follow-up after treatment.

Portosystemic arteriovenous fistulas.

The authors report the angiographic demonstration of arteriovenous fistulas in three patients. The fistula was believed to be spontaneous in one case, related to abdominal surgery and to abdominal trauma in the other two cases. The importance of angiography in the diagnosis and evaluation of this disease has been emphasized in the literature. Early diagnosis is valuable, either to prevent hepatic damage or to give an opportunity for recovery once it has taken place. Follow-up of the three patients has shown that hepatic function notably improved after surgery.

[Lumbar epidural anesthesia in peripheral arteriography].

A brief survey of the difficulties associated with the intra-arterial administration of contrast media during peripheral arteriography is followed by an assessment of anaesthesiological and arteriographic results obtained with lumbar peridural anaesthesia in a group of patients. Complete analgesia, block of the sympathic, and motor block gave particular assistance in the securing of optimum definition of the radiographical picture of the peripheral circulation. These and other advantages offered by peridural anaesthesia suggest that it is a valid technique for peripheral arteriography.

Ultrasound and CT findings in two cases of hemangioma of the adrenal gland.

The ultrasound and CT findings in two patients with hemangioma of the adrenal gland are presented. Ultrasound showed large masses with heterogeneous nonspecific structural pattern. Unenhanced CT demonstrated lesions with hypodense centers and thick irregular peripheries with higher density. A few small peripheral calcifications were noted in one patient. Following contrast medium injection, patchy enhancement of the peripheral zone of the tumor was seen in both cases.

[The preoperative staging of rectal neoplasms: the clinical exam and diagnostic imaging].

The management of rectal cancer remains an important clinical problem. Although there was been great progress in surgical management, the survival of patients with locally advanced disease has not improved significantly during the past decades. Preoperative staging and evaluation of the risk of recurrence may help in the choice of operation. It is difficult for clinicians to quantify reliably with digital examination the degree of fixation of the tumor, and they usually cannot distinguish nodal metastases except in advanced cases. The more frequent overstaging of small tumors within one quadrant of the rectum is a major drawback of digital examination. Computed tomography and magnetic resonance seems to underestimate the extension of rectal tumors, but both can be helpful in selecting patients with advanced tumors for whom preoperative adjuvant treatment is being considered. Endoluminal ultrasound is superior in staging tumors confined to the rectal wall, but is not the ideal tool for staging: the results are examiner dependent, the field of vision in depth is limited, and stricturing tumors cannot be passed by the ultrasound transducer. Imaging diagnostic attendibility confirms the preeminent role of intraoperative exploration in the assessment of neoplastic diffusion in order to plan a correct surgical treatment.

[Radiofrequency thermal ablation of hepatic nodules: selection criteria for percutaneous treatment].

Radiofrequency thermal ablation (RFA) of liver tumor is done by percutaneous, laparoscopic and open surgical approach. Selection criteria for percutaneous or open surgical ablation of 54 hepatic lesions are here evaluated in 30 consecutive patients. Open surgical approach was performed in 9 cases only, 5 of them due to concomitant treatment of associated diseases. Number and size of the lesions did not interfere with surgical approach. Postoperative CT control showed no differences in terms of complete ablation of the tumor in between the two groups of patients. Percutaneous approach of RFA is gone to be in the future the modality of choice in these patients.

[Thermal ablation by radiofrequency of hepatic metastasis of colorectal cancer: short-term results].

Radiofrequency (RF) was used to ablate 42 colorectal liver metastases in 20 patients (10 males and 10 females) in a four years period. Median age was 62.2 years, 36 lesions (75%) had 3 cm diameter or less. An open surgical approach was adopted in 13 patients, whereas a percutaneous one in 14. On 27 surgical sessions, RFA was used in 49 procedures for a total of 81 needle applications. Morbidity was 6.0% (3 cases), one patient died on third po day for myocardial infarction. No differences in terms of complete ablation rate was observed in the two approach's groups. Overall survival was 65% with a median follow-up of 18.5 months.
