ABSTRACT

Bowel infarction commonly presents as an acute abdomen that rapidly progresses to severe shock. The diagnosis is often not clinically suspected. Three cases are described where the diagnosis was made during dynamic contrast enhanced computed tomography (CT), when gas was demonstrated in the portal venous system and liver. Two patients died during surgery, the third survived because of the prompt diagnosis made on CT, and subsequent surgical treatment. The radiological findings are reviewed.

ABSTRACT

Visualization of pre-cervical soft tissue swelling on a lateral radiograph is an important indicator of possible bony injury in the context of cervical spine trauma. We report a case where apparent swelling was in fact an artefact due to an inappropriately placed endotracheal tube. We recommend review of the position of endotracheal tubes when interpreting pre-cervical soft tissue swelling.

ABSTRACT

OBJECTIVE: The purpose of this study was to evaluate the efficacy and complications of percutaneous 18-gauge core biopsies of lesions of the bowel wall using CT and sonographic guidance. A retrospective study was made of 15 biopsy procedures performed on 12 patients with suspected neoplasia of the gastrointestinal tract. The biopsies were performed when there were no sites of metastatic disease more readily accessible to biopsy and the lesion was inaccessible to endoscopic techniques or when the endoscopic biopsy findings were negative. CONCLUSION: Three biopsy procedures provided inadequate samples and the biopsies were repeated, giving a total of 15 biopsy procedures. A tissue diagnosis was made in all 12 patients. All procedures were well tolerated, and no immediate or delayed complications occurred. Percutaneous core biopsy of bowel wall masses is a safe technique that allows a histologic diagnosis to be obtained in difficult cases when other methods cannot provide an adequate tissue sample.

ABSTRACT

We present a case in which a strangulated incisional hernia following a renal transplant was sonographically diagnosed. The patient presented with acute pain and swelling over the transplant site 6 weeks after surgery. Sonograms showed a normal-sized kidney with normal echotexture, no evidence of hydronephrosis, and no perinephric collections. Color Doppler sonography and spectral analysis demonstrated normal blood flow throughout the kidney. Sonograms showed that the palpable mass was a dilated loop of fluid-filled small bowel. Sonography allowed the correct diagnosis to be established, and early surgical intervention allowed revascularization of viable bowel.

ABSTRACT

We studied the position of the popliteal artery in 32 patients with primary osteoarthritis of the knee. A total of 45 knees were studied using a noninvasive technique with color-flow duplex scanning. The distance between the popliteal artery and the posterior tibial cortex was measured in various positions of flexion. The distance separating them was found to be maximal between 60 degrees and 90 degrees. The study was repeated in a smaller series of 17 patients (20 knees) after knee replacement but with less conclusive results. We believe the safest position on which to operate in primary arthroplasty is with the knee in flexion, but the safety margins are not the same in revision surgery.

ABSTRACT

Three patients who were investigated with dynamic contrast medium enhanced computed tomography (CT) of the thorax were noted to have pericardial effusions with reflux of contrast medium back along the azygos vein. The diagnosis of cardiac tamponade was not made clinically, but in each case was suggested from the CT findings. Confirmation of the diagnosis was made in all three cases, two patients with echocardiography and one at post mortem. One patient made a rapid recovery following the insertion of a pericardial drain, another made a temporary recovery after pericardiocentesis but the third died. Thirty CT scans performed with similar protocol were reviewed and none of these demonstrated reflux along the azygos vein. The presence of contrast medium refluxing into the azygos vein implies significant haemodynamic disturbance, and in the presence of a pericardial effusion suggests the diagnosis of cardiac tamponade.

ABSTRACT

The first long-term follow-up of the use of the Antheor inferior vena cava (IVC) filter is presented. Between December 1994 and December 1996, 20 Antheor IVC filters were inserted. Seven patients subsequently died and of the 13 patients remaining alive, 11 were available for long-term follow-up. One death was due to migration of the filter to the main pulmonary artery 6 weeks after insertion and because of this case, and other similar reports, the filter has now been withdrawn from clinical use. Of the 11 filters assessed at follow-up, three were fractured. One filter contained thrombus and one IVC was occluded. Our experience highlights the problem of central migration, but also shows a high incidence of filter fracture which has not previously been described with this design of filter.

ABSTRACT

Calcific tendinitis of the gluteus maximus tendon is unusual and only eight cases associated with erosions of cortical bone have been reported. We present three further cases which demonstrate variation in appearances of the amorphous calcification in the tendon and cortical erosions on plain radiographs. Isotope bone scans show focal increased activity and computed tomography (CT) clearly demonstrates erosion of cortical bone and calcification within the tendon insertion of gluteus maximus. Follow-up examinations in two cases demonstrated resolution of the changes. We believe this series demonstrates the radiological features and natural history of a common condition occurring at an unusual site. Its recognition is important in order to avoid unnecessary surgical intervention. Resolution of the calcification and cortical erosions has not been previously described.
