We describe three cases with acute middle cerebral artery (MCA) occlusion. From the pre-operative MRI, including three-dimensional turbo spin-echo sequences using T1WI and T2WI, we assessed both thrombus configuration and arterial anatomy at the MCA bifurcations. For efficient endovascular thrombectomy, we identified the applied MCA segment 2 (M2) branch, in which the main thrombus was buried. Sufficient recanalization after a single pass was achieved and the patients made a marked recovery. Although mechanical thrombectomy for M2 occlusion has not been of proven benefit, the endovascular procedure based on three-dimensional turbo spin-echo imaging is useful for more complete thrombus removal at MCA bifurcations. 相似文献

Adult T-cell leukemia/lymphoma (ATL/L) is clustered in southwesternJapan, especially in the Nagasaki and Kagoshima areas. It wasshown that this clustering correlated with the presence of antibodiesto antigens of a new C-type RNA leukemia virus. Surface markeranalysis of neoplastic T-cells of ATL/L patients shows the helper/inducerphenotype (Leu-1+, Leu-2a and Leu-3a+). On the other hand, the association between T-cell malignancyincluding ATL/L and monoclonal gammopathy is very rare. Threeunique cases of ATL/L with monoclonal gammopathy are reported.Yet the meaning of an M-component in T-lymphocytic proliferationremains uncertain. The relationship between the leukemia virus,ATL/L-cells and monoclonal gammopathy is discussed. 相似文献

Mid-Diastolic Potential in Idiopathic VT. We report a case of verapamil-sensitive idiopathic ventricular tachycardia in which a mid-diastolic potential (MDP) 45 msec preceding the Purkinje potential ( P potential) was recorded. Pacing during the tachycardia caused concealed entrainment, and the stimulus–QRS interval was equal to the P potential–QRS interval. The interval between the last pacing stimulus and the next P potential (postpacing interval) was longer than the ventricular tachycardia cycle length, but the MDP was orthodromically activated. These findings suggest that the MDP was on the reentrant circuit and the P potential was not on the reentrant circuit, but a bystander. 相似文献

Acute Effects of Different Atrial Pacing Sites in Patients with Atrial Fibrillation: Comparison of Single Site and Biatrial Pacing 总被引:4,自引:0,他引:4
MASAHIRO OGAWA KAZUHIRO SUYAMA TAKASHI KURITA WATARU SHIMIZU KIYOTAKA MATSUO ATSUSHI TAGUCHI NAOHIKO AIHARA SHIRO KAMAKURA KATSURO SHIMOMURA 《Pacing and clinical electrophysiology : PACE》2001,24(10):1470-1478
It has been reported that a trial single site or biatrial pacing can suppress the occurrence of AF. However, its mechanism remains unclear. The study population included 32 patients with AF (n = 20: AF group), or without paroxysmal AF (n = 12: control group). The mechanism and efficacy of atrial pacing were investigated by electrophysiological studies to determine which was more effective for suppressing AF induction; single site pacing of the right atrial appendage (RAA) or distal coronary sinus (CS-d), or biatrial (simultaneous BAA and CS-d) pacing. In the AF group, AF inducibility was significantly higher with BAA extrastimulus during RAA (12/20; P < 0.0001) or biatrial paced drive (7/20; P < 0.01) than during CS-d paced drive (0/20). In the control group, AF was not induced at any site paced. In the AF group, the conduction delay and other parameters of atrial vulnerability significantly improved during CS-d paced drive. The atrial recovery time (ART) at RAA and CS-d was measured during each basic pacing mode. ART was defined as the sum of the activation time and refractory period, and the difference between ARTs at RAA and CS-d was calculated as the ART difference (ARTD). The ARTD was significantly longer during BAA pacing in the AF group than in control group (155.0 +/- 32.8 vs 128.8 +/- 32.9 ms, P < 0.05). In the AFgroup, ARTDs during biatrial (52.0 +/- 24.2 ms) and CS-d pacing (51.7 +/- 26.0 ms) were significantly shorter than ARTD during RAA pacing. The CS-d paced drive was more effective for suppressing AF induction than biatrial or RAA paced drive by alleviating conduction delay. CS-d and biatrial pacing significantly reduced ARTD compared with RAA pacing. 相似文献

Ten periodontally affected subjects and 10 healthy subjects were selected in order to examine the duration patterns of percussion sounds in all upper teeth, excluding the 8's. Probing depth, loss of attachment, tooth mobility by 'Periotest', bone loss and percussion sound duration via occlusal sound analyser were recorded during the pretreatment period. The following results were obtained from the study: (i) the normal duration of percussion sounds ranged from 4.40-5.33 ms; (ii) percussion sound values of periodontal patients were of longer duration than those of healthy subjects; (iii) a close correlation between duration and other individual parameters was found in all upper teeth, with the exception of molars. 相似文献

A 30-year-old previously healthy housewife presented with bilateralpulmonary infiltrates. She was treated with various antibioticsbut died with disseminated intravascular coagulation. Culturesof tracheal aspirates obtained prior to her death yielded Trichosporonbeigelii. Postmortem examination revealed T. beigelii pneumoniawith fungal dissemination in other organs. In addition, manyorgans were found to be infiltrated with atypical mononuclearcells which exhibited cytochemical properties of histiocytes.It was considered, therefore, that T. beigelii pneumonia developedon the basis of underlying malignant histiocytosis. T. beigeliiin her lung sections was fluorescently stained with rabbit antiserumto the fungus isolated from the patient. This is the first reportof Trichosporon beigelii pneumonia associated with malignanthistiocytosis. 相似文献

The retrograde atrial potential at a successful ablation site is usually obscured by the wide and large ventricular potential during atrioventricular reentrant tachycardia or ventricular pacing, which makes it difficult to determine the appropriate ablation site for concealed accessory pathway. A pacing maneuver named the “simultaneous pacing method” is proposed herein to differentiate the retrograde atrial potential from the ventricular potential for a successful ablation of the concealed accessory pathway. Catheter ablation was performed in 12 patients with a single left free-wall concealed accessory pathway. The atrial insertion site was determined by the simultaneous pacing method in six patients (group I) and by ventricular pacing in six patients (group II), In the simultaneous pacing method, electrograms recorded during ventricular pacing in the earliest retrograde atrial activation site are a fusion of the ventricular potential and the following retrograde atrial potential. When atrial and ventricular pacings are performed simultaneously (simultaneous pacing), the end portion of the electrograms recorded at the same site is solely the ventricular component, because atrial is activated earlier. The atrial potential can be confirmed during ventricular pacing in comparison with the electrograms during the “simultaneous pacing.” Radiofrequency catheter ablation was successful in eliminating conduction through the accessory pathway in all 12 patients. The radiofrequency applications in group I were significantly fewer than those in group II (1.7 ± 1.0 in group I, 5.3 ± 3.2 in group II, P < 0.05). The total procedure time in group I was significantly shorter than in group II (57.8± 15.7 vs 106.7 ± 41.6 mins in group II. respectively, P < 0.05). The fluoroscopy time in group I was significantly shorter than in group II (54.0 ± 7.9 vs 81.3± 26.3 mins, respectively, P < O.05). We were able to determine the atrial insertion site of accessory pathways by the simultaneous pacing method. The simultaneous pacing method was useful in eliminating concealed left free-wall accessory pathways. 相似文献

We report the first case of human herpesvirus-6 (HHV-6) associated exanthema in a patient with acute lymphocytic leukaemia (ALL). We analysed DNA extracted from an exanthematous lesion using the polymerase chain reaction (PCR). DNA was positive for HHV-6 but negative for herpes simplex virus, varicella zoster virus, and cytomegalovirus. Immunohistochemical staining of the skin with monoclonal antibody against HHV-6 confirmed the infection. The possibility of HHV-6 infection should be considered when an atypical skin rash is seen in patients with ALL. 相似文献
