Abstract: Endoscopic injection sclerotherapy (EIS) is widely accepted as a means of treating esophageal varices. However, various complications of EIS have been reported. To investigate the cause of chest complications after EIS, chest CT and bronchofiberscopy (BF) were carried out in patients undergoing EIS. A contrast medium was added to the sclerosant in a 1: 4 ratio, and a chest CT examination was performed 30 minutes after the EIS procedure. BF was performed before and after EIS. CT findings were classified into four types, i. e., Type I : ring-enhanced esophageal wall, Type II : ring-enhanced paraesophageal wall, Type III : locally enhanced esophageal wall, and Type IV : beltlikeenhanced parietal pleura. The CT findings depended on the frequency of EIS rather than the total volume of sclerosant. After injection into the Paravariceal wall, the sclerosant unexpectedly moved beyond the local injection site during the first or second EIS procedures. During the third or subsequent procedures the sclerosant tended to abide locally in the esophageal wall. Before EIS, bronchial venous dilatation, present mainly in the left main bronchus, was noted and its degree was correlated with the form and location of the esophageal varices. Bronchial venous dilatation decreased in three patients after EIS. The change in venous dilatation seemed to reflect alterations in the esophageal variceal blood flow. After EIS bronchial ulceration was found in the main bronchus in 3 patients. This phenomenon was attributed to both the direct effects of the sclerosant and the physical effects of the endoscopic examination itself: Minor complications such as pleural effusion, chest pain, and fever were not associated with either CT or BF findings. Patients undergoing EIS should be carefully monitored to facilitate the early detection and management of potential chest complications. 相似文献

Transoesophageal echocardiography disclosed a localized pericardialblood clot compressing the right atrium (RA) and/or right ventricle(RV) in 15 patients suffering from low cardiac output failuresoon after open-heart surgery. The left ventricular end-diastolicdiameter was small (38.4 ± 10.1 mm) and its fractionalshortening normal (34.9 ± 10.2%). These findings suggestedcardiac tamponade as a result of pericardial clot. However,the y trough of the RA pressure tracing was prominent,which is not characteristic of typical cardiac tamponade, butrather of constrictive pericarditis. This implies thereforethat the pathophysiology of cardiac tamponade by pericardialclot differs from that of tamponade by fluid. Emergency open-chestremoval of the pericardial clot was performed in seven patients,with good results. Pericardial clot produces low cardiac outputsoon after open-heart surgery, but its location is specificand its haemodynamics are not characteristic of cardiac tamponade. 相似文献

Abstract Clinically apparent hematogenous skeletal muscle metastases from lung cancer are extremely rare. We present a 72-year-old man with a large cell lung carcinoma metastatic to nuchal muscle. Cervical computed tomography (CT) and magnetic resonance imaging (MRI) revealed the presence of a well-defined mass in the left splenius capitis muscle. A percutaneous needle biopsy was performed to establish a diagnosis. Localized skeletal muscle swelling may rarely prove to be metastases in patients with lung cancer, but should be investigated in the case of muscle swelling. 相似文献

Aim: It is a common belief that terminally ill cancer patients have a reduced tissue tolerance that makes them more susceptible than other patients to developing pressure ulcers. However, the actual changes at the tissue level caused by pressure loading in terminally ill cancer patients are unknown, so we examined the relationship between the macroscopic and microscopic features of the tissues of such patients with and without pressure ulcers. Methods: The pressure ulcers of four patients were macroscopically evaluated until the time of death, after which informed consent of the family was obtained to examine the underlying skin tissue histologically. Samples were taken from several sites on the abdomen, which does not experience pressure loading, and from the sacral area. Two of the subjects had no observable pressure ulcers and the other two had a stage I and stage II (National Pressure Ulcer Advisory Panel classification) pressure ulcer, respectively. The samples were processed, stained and examined by using light and transmission electron microscopy. Results: The non‐pressure ulcer samples showed degenerated keratinocytes, leakage of erythrocytes from the capillaries in the dermal papillae, vascular inflammation, and edema. The samples from the stage I and II ulcers had the additional changes of dilated capillaries and vascular inflammation in and around the wound area. Conclusion: Terminally ill cancer patients have damaged skin tissue and inflammation that are not evident by macroscopic examination. 相似文献

Comparison of continuous epidural infusion of morphine/bupivacaine with fentanyl/ bupivacaine for postoperative pain relief 总被引:3,自引:0,他引:3

The efficacy and safety of postoperative analgesia with continuous epidural infusion of either morphine or fentanyl in combination with bupivacaine were evaluated in 85 patients, ASA physical status I or II, undergoing thoracic and/or upper abdominal surgery. Patients were treated with one of the combinations for 48 h after surgery. The morphine/bupivacaine group (MB; n = 45) received morphine at the rate of 0.2 mg h-1 , and bupivacaine at the rate of 10 mg h-1 for the first 24 h or 5 mg h-1 for the second 24 h; the fentanyl/bupivacaine group (FB; n = 40) received fentanyl at the rate of 20 μg–h-1 , and bupivacaine at the rate of 10 mg h-1 for the first 24 h or 5 mg h-1 for the second 24 h. The degree of pain relief assessed by the visual pain scale and the modified Prince Henry pain scale was satisfactory in most patients in both groups. In group MB 74% and in group FB 76% of patients did not need any supplementary analgesics. No significant differences were observed between the groups in assessment of pain. The incidence of hypotension ( P < 0.05) and pruritus ( P < 0.05) was higher in group MB than in group FB. None of the patients developed respiratory depression in either group. 相似文献

A superficial artery may be present in the forearm, arising from the axillary, brachial or superficial brachial arteries and crossing over the origin of the flexor muscles of the forearm to reach the palm (Adachi, 1928; Bergman et al. 1988). When this superficial artery continues as the normal ulnar artery accompanying the ulnar nerve at the wrist, it is referred to as the superficial ulnar artery, with an incidence of ∼4%. When the artery passes below or superficial to the flexor retinaculum in the middle of the forearm, sometimes continuing to join the superficial palmar arch, it is called the superficial median artery, with an incidence of ∼1%. We have observed a relatively rare variation involving the presence of a superficial median artery in both upper limbs. We discuss the clinical importance and the developmental aspects of this arterial variation. 相似文献
