Bleeding Site (bleeding + site)
Selected AbstractsSimplified treatment of massive rectal bleeding following prostate needle biopsyINTERNATIONAL JOURNAL OF UROLOGY, Issue 7 2004MURAT GONEN Abstract Rectal bleeding is frequently seen in patients undergoing transrectal ultrasound-guided prostate biopsy, but it usually stops spontaneously. We report a case of life-threatening rectal bleeding following this procedure. Bleeding was controlled using an ordinary condom, which was successfully inflated in the rectum over the bleeding site.

The prognosis in patients with a ruptured hepatocellular carcinoma is usually unfavourable. We describe a 46-year-old man who suffered from visible massive tumour haemorrhage due to a hepatitis B-related hepatocellular carcinoma that metastasized to the sternal bone. The prominent tumour mass was bulging over the anterior chest wall on the sternum of the patient, and bled spontaneously. This episode of life-threatening haemorrhage was stopped by surgical ligation of the bleeding site. Palliative radiotherapy shrank the tumour mass size and prevented further possible bleeding. This is likely to be the first reported case with a visible spontaneous tumour bleeding from a sternal metastatic hepatocellular carcinoma. [source] Multi-detector CT angiography for lower gastrointestinal bleeding: Can it select patients for endovascular intervention?JOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 1 2010PT Foley§ Summary This is a retrospective review of the results at our institution of using multi-detector CT angiography (CTA) to localise lower gastrointestinal (GI) bleeding. We hypothesised that in our patient population: (i) CTA was unlikely to demonstrate bleeding in patients who were haemodynamically stable; (ii) in haemodynamically unstable patients in whom CTA was undertaken, the results could be used to select patients who would benefit from catheter angiography; and (iii) in haemodynamically unstable patients in whom CTA was undertaken, a subgroup of patients could be identified who would benefit from primary surgical treatment, avoiding invasive angiography completely. A retrospective review was conducted of the clinical records of all patients undergoing CTA for lower GI haemorrhage at our institution between 1 January 2005 and 30 June 2007. Out of the 20 patients examined, 10 had positive CTAs demonstrating the bleeding site. Nine were haemodynamically unstable at the time of the study. Four patients with positive CT angiograms were able to be treated directly with surgery and avoided invasive angiography. Ten patients had negative CTAs. Four of these were haemodynamically unstable, six haemodynamically stable. Only one required intervention to secure haemostasis, the rest stopped spontaneously. No haemodynamically stable patient who had a negative CTA required intervention. CTA is a useful non-invasive technique for localising the site of lower GI bleeding. In our patient population, in the absence of haemodynamic instability, the diagnostic yield of CTA was low and bleeding was likely to stop spontaneously. In haemodynamically unstable patients, a positive CTA allowed patients to be triaged to surgery or angiography, whereas there was a strong association between a negative CTA and spontaneous cessation of bleeding. [source] Major differences in bleeding symptoms between factor VII deficiency and hemophilia BJOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 5 2009F. BERNARDI Summary.,Background:,The autosomally-inherited factor VII (FVII) deficiency and X-linked hemophilia B offer an attractive model to investigate whether reduced levels of FVII and FIX, acting in the initiation and amplification of coagulation respectively, influence hemostasis to a different extent in relation to age and bleeding site. Methods:,Hemophilia B patients (n = 296) and FVII-deficient males (n = 109) were compared for FVII/FIX clotting activity, F7/F9 genotypes and clinical phenotypes in a retrospective, multi-centre, cohort study. Results:,Major clinical differences between diseases were observed. Bleeding occurred earlier in hemophilia B (median age 2.0 years, IR 0.9,5.0) than in FVII deficiency (5.2 years, IR 1.9,15.5) and the bleeding-free survival in FVII deficiency was similar to that observed in ,mild' hemophilia B (P = 0.96). The most frequent disease-presenting symptoms in hemophilia B (hematomas and oral bleeding) differed from those in FVII deficiency (epistaxis and central nervous system bleeding). Differences were confirmed by analysis of FVII-deficient women. Conclusions:,Our data support the notion that low FVII levels sustain hemostasis better than similarly reduced FIX levels. On the other hand, minute amounts of FVII, differently to FIX, are needed to prevent fatal bleeding, as indicated by the rarity of null mutations and the associated life-threatening symptoms in FVII deficiency, which contributes towards shaping clinical differences between diseases in the lowest factor level range. Differences between diseases are only partially explained by mutational patterns and could pertain to the specific roles of FVII and FIX in coagulation phases and to vascular bed-specific components. [source] Systemic granulomatous necrotizing vasculitis in a MPO,ANCA-positive patientPATHOLOGY INTERNATIONAL, Issue 8 2004Atsushi Kurata We present a case of myeloperoxidase antineutrophil cytoplasmic antibody (MPO,ANCA)-associated vasculitis that demonstrated a systemic granulomatous lesion at autopsy. The patient initially showed anorexia, general malaise and anemia. Colon fiber was examined to detect the bleeding site, which revealed ischemic mucosal damage associated with venous fibrin thrombus. Because a high titer of MPO,ANCA was found, ANCA-associated vasculitis was suspected and the patient was started on steroid pulse therapy. However, anemia, renal failure and respiratory failure worsened and the patient died of sudden cardiac failure 2 days after the start of the therapy. An autopsy revealed systemic arteritis in multiple organs including the kidneys, liver, spleen, gastrointestinal system and genital organs that indicated fibrinoid necrosis accompanied by granulomatous reaction with multinucleated giant cells; the granulomatous reaction further extended along the splenic capsule. Glomerulonephritis and diffuse pulmonary damage, which are common in MPO,ANCA-associated vasculitis, were almost absent but parapleural fibrosis was present. The direct cause of death was presumed to be hemorrhagic shock due to rupture of an aneurysm in the gastric subserosa. As far as we know, this is the first case of a systemic granulomatous reaction in MPO,ANCA-positive vasculitis, although the cause of the granulomatous lesion is unknown. [source] Unusual Vaginal Angiomatous Neoformation in a 3-year Old PugREPRODUCTION IN DOMESTIC ANIMALS, Issue 2 2008M Beccaglia Contents A 3-year-old female pug (8 kg bodyweight) was referred by a local veterinarian for evaluation of vaginal bleeding. Historically, the owner indicated chronic haematic vaginal discharge initiated approximately 3 months ago, overall good appetite and slight general dullness. Two months prior to the visit, the bitch had been spayed by the local veterinarian, but vaginal bleeding persisted after surgery. Following a general examination and complete blood analysis, a genital tract examination was performed and, through vaginal endoscopy, a red, smooth, and apparently broad-based vaginal mass was found. An episiotomy was performed and on surgical exploration, the bleeding site was determined to be on the surface of a mass composed of two congested, adjacent cylindrical structures, symmetric to the vaginal sagittal midline, broad-based and quite regular on the surface. The mass appeared to be well delimited from the surrounding tissue by a thin capsula, and each cylindrical structure had a tributary vessel. Ectopic and dysplastic corpora cavernosa of the clitoris characterized by angiomatous proliferation, cavernous haemangioma and vascular hamartoma were considered in the differential diagnosis. The presence of small intralesional nerves identified by S100 immunostaining was used as a diagnostic clue to classify this unusual vaginal angiomatous neoformation as vascular hamartoma. [source] Changes in left ventricular ejection time and pulse transit time derived from finger photoplethysmogram and electrocardiogram during moderate haemorrhageCLINICAL PHYSIOLOGY AND FUNCTIONAL IMAGING, Issue 3 2009Paul M. Middleton Summary Objectives:, Early identification of haemorrhage is difficult when a bleeding site is not apparent. This study explored the potential use of the finger photoplethysmographic (PPG) waveform derived left ventricular ejection time (LVETp) and pulse transit time (PTT) for detecting blood loss, by using blood donation as a model of controlled mild to moderate haemorrhage. Methods:, This was a prospective, observational study carried out in a convenience sample of blood donors. LVETp, PTT and R-R interval (RRi) were computed from simultaneous measurement of the electrocardiogram (ECG) and the finger infrared photoplethysmogram obtained from 43 healthy volunteers during blood donation. The blood donation process was divided into four stages: (i) Pre-donation (PRE), (ii) first half of donation (FIRST), (iii) second half of donation (SECOND), (iv) post-donation (POST). Results and conclusions:, Shortening of LVETp from 303+/,2 to 293+/,3 ms (mean+/,SEM; P<0·01) and prolongation of PTT from 177+/,3 to 186+/,4 ms (P<0·01) were observed in 81% and 91% of subjects respectively when comparing PRE and POST. During blood donation, progressive blood loss produced falling trends in LVETp (P<0·01) and rising trends in PTT (P<0·01) in FIRST and SECOND, but a falling trend in RRi (P<0·01) was only observed in SECOND. Monitoring trends in timing variables derived from non-invasive ECG and finger PPG signals may facilitate detection of blood loss in the early phase. [source] Variability in bleeding phenotype in Amish carriers of haemophilia B with the 31008 C,T mutationHAEMOPHILIA, Issue 1 2009A. SHARATHKUMAR Summary., The aim of this study was to characterize the variability of bleeding phenotype and its association with plasma factor IX coagulant activity (FIX:C) in haemophilia B carriers in a large Amish pedigree with a unifying genetic mutation, C-to-T transition at base 31008 of the factor IX gene (Xq27.1,27.2). A cross-sectional survey of haemophilia B carriers included a multiple choice questionnaire evaluating symptoms of mucocutaneous bleeding, joint bleeding and bleeding after haemostatic stress [menstruation, postpartum haemorrhage (PPH), dental extractions and invasive surgeries]. Severity of bleeding was graded as 0 to 4, 0 being no bleeding whereas 4 being severe bleeding. Association between total bleeding scores and the FIX:C was evaluated. Sixty-four haemophilia B carriers participated in this study. Median age: 18 years (range 1,70 years); median bleeding score: 1 (range 0,8). Besides PPH, isolated symptoms of bruising, epistaxis, menorrhagia and postsurgical bleeding including dental extraction were not associated with lower FIX:C. Bleeding score ,3 was associated with involvement of at least two bleeding sites and a lower mean FIX:C of 42 ± 10.3% (95% CI 36.4,47.7) while a score >3 had involvement of ,2 sites and higher mean FIX:C of 54.9 ± 21.5% (95% CI 49,61), P = 0.005. Subcutaneous haematoma formation and bleeding after haemostatic stress requiring treatment were associated with bleeding scores ,3. Phenotypic variability existed among the carriers of haemophilia B who belonged to a single pedigree carrying a single unifying mutation. The utility of bleeding scores to define bleeding phenotype precisely in haemophilia B carriers needs further evaluation. [source] |
