A case of acute myocardial infarction treated with a new thrombectomy system.

Thrombotic occlusion in the culprit lesion of acute myocardial infarction was successfully recanalized using a 4.5 Fr thrombectomy catheter (RESCUE), which was also used to normalize the coronary blood flow. The retrieved specimens were white thrombi containing red thrombi and cholesterol crystals, indicating plaque rupture.     

Blood flow measurement of brain tumor by 123I-IMP using 3-heads rotating gamma camera SPECT]

Using 3-heads rotating gamma camera SPECT system, regional blood flow was measured from the super-early image obtained 4 to 6 minutes after the intravenous injection of 123I-IMP on 11 patients with various brain tumors. Two cases of olfactory groove meningioma and malignant astrocytoma showed significantly high 123I-IMP uptake by the lesion visualized by MRI compared to the uptake by normal brain cortex on super-early image but 123I-IMP uptake by the tumor decreased on early image. In both cases, blood flow of the tumor measured from super-early image showed values much higher than those of normal brain cortex. It was thought that usual correction method based on early image did not correctly represent the blood flow of the lesion but that the present method based on super-early image could show the increase of blood flow of the tumor.     

Clinical examination of torsion of the spermatic cord--review of 177 cases reported in the recent Japanese literature including our present 7 cases

Between January 1974 and December 1984, 16 patients underwent surgical exploration at our Hospital. Seven of these patients proved to have torsion of the spermatic cord and nine were strongly suspected to have this lesion in spite of lack of torsion during operation and the remaining 3 patients suffered from epididymitis. The 7 patients with torsion ranged in age from 14 to 22 years old. The left side was involved in 4 patients, and the right side in 3 patients. Six patients had internal rotation and 1 had external rotation. In all of them, intravaginal torsion was noticed at various degrees of twist (270 degrees-540 degrees). Orchidopexy was performed in 5 cases in which the operation could be done within 15 hours after onset of the symptom but in 2 cases in which 50, and 56 hours had elapsed orchidectomy was unavoidable. The 177 cases reported in the Japanese literature since Kumon's report including our present 7 cases were reviewed statistically in detail. Case reports of this lesion, especially in newborns, is increasing every year. The age distribution showed two peaks, one at the time of puberty (10-19 years old) and the other shortly after birth. There was a predominance for the left side, internal rotation and twisted degrees of 180 degrees to 360 degrees in this series. In the cases in which over 24 hours has elapsed before surgery, orchidectomy was performed frequently.     

Risk Factors for Clinical Pancreatic Fistula After Distal Pancreatectomy: Analysis of Consecutive 100 Patients

Background  

The mortality associated with distal pancreatectomy (DP) has declined to <5% in recent years in high-volume centers. However, morbidity remains high, ranging from 32% to 57%. Pancreatic fistula (PF) is the most common complication after DP. The aim of this study was to analyze factors associated with the occurrence of clinical PF.
