A coronary pseudostenosis is a characteristic angiographic image, which may appear as coronary winkles, or intussusceptions, due to a stiff guidewire during coronary interventions. Intravascular ultrasound (IVUS) plays a role in ruling out severe coronary stenosis, coronary dissections, thrombus or coronary spasm. We report a case of coronary pseudostenosis, which occurred during coronary interventions, diagnosed by intravascular ultrasound.

PURPOSE: The purpose of this study was to investigate the predictive factors of saline reduction under ultrasound-guidance in patients with intussusception. METHODS: Ultrasound-guided saline enema reductions were performed in 105 patients with intussusception from September 1993 to April 1996 at Ewha Womans University Mok-dong Hospital. Clinical characteristics and ultrasonographic findings were analyzed as the predictive factors of ultrasound-guided saline enema reduction in 15 patients(14.3%) who were not reduced by saline enema reduction compared to 90 patients(85.7%) who were reduced. RESULTS: The mean age of the not-reduced group was 8.9+/-5.8 months old which was significantly younger than 14.5+/-15.4 months old of the reduced group(P<0.05) There were no significant differences in sex and clinical symptoms between the two groups(P>0.05). Among the ultrasonographic findings, the thickness of the hypoechoic outer rim in the not-reduced group was 10.5+/-3.3mm which was significantly thicker than 7.4+/-1.8mm of the reduced group(P<0.05). In stepwise logistic regression analysis, hypoechoic outer rim thickness over 8mm contributed significantly as the predictive factor for the failure of ultrasound-guided saline enema reduction(P<0.05). CONCLUSION: The thickness of the hypoechoic outer rim over 8mm on ultrasonogram was the predictive factor for the failure of saline reduction.

Isolated small bowel intussusception accounts for 10% of all pediatric intussusception. It is more common in children older than 2 years of age. Presentation usually is with vomiting and abdominal pain. Currant jelly stool and palpable mass are less frequent than typical intussusception. There are few reported cases of children with transient small bowel intussusception. We describe 3-year-old boy presented with intermittent cyclic crampy abdominal pain for 6 months was diagnosed as having recurrent transient small bowel intussusception by abdominal ultrasonography and small bowel series.

A gastrointestinal lipoma, though rare, is a mesencymal tumor of the large bowel, and the second most common benign colonic tumor detected after an adenomatous polyp. The lesion may be asymoptomatic when small and may be detected incidentally, usually during a colonoscopic examination for another purpose. Lipomas of the large bowel that are not causing symptoms probably need no treatment, as malignant transformation has not been documented. If the mass is large, it can cause pain, anal bleeding due to intussusception, bowel obstruction and diarrhea, and thus resection should be considered. Due to the risk of perforation, endoscopic resection of large colonic lipomas has been discouraged. However, large colonic lipomas can be removed safely by endoscopic resection with the use of an endoscopic ultrasonogram and submucosal injection to elevate the lesion.

A Yorkshire terrier (case 1) and a Miniature Schnauzer (case 2) were diagnosed with pylorogastric intussusceptions (PGIs). Both cases showed acute vomiting and had previous histories of laparotomy. In case 1, the invaginated pyloric wall was thickened unevenly containing multiple hypoechoic areas and had indistinct wall layering on ultrasonography. PGI with diffuse gastric edema and necrosis was confirmed on laparotomy. The dog recovered completely after gastrectomy and a Y-U plasty. Case 2 had uniformly thickened walls of invaginated gastric pylorus with the distinct wall layering. PGI was reduced spontaneously the next day.
