[en] To report our experience of managing extensive retroperitoneal hematoma (RH) in patients with blunt trauma and to determine any associated factors affecting causation and mortality. In this retrospective observational study, patients diagnosed with extensive RH following blunt trauma admitted to King Saud Medical Complex, Riyadh, Kingdom of Saudi Arabia between January 2004 and December 2009 were included. Patient data were explored for injury severity score (ISS), associated injuries, location of hematoma, amount of blood transfusions, coagulation profile, operative management, hospital stay, and mortality. The outcomes in surviving and non-surviving patients were compared. Out of 290 patients presenting with RH, extensive RH was found in 46 patients (15.8%). The overall mortality was 32.6%. The pelvis was the most frequent location of RH in combination with lateral and central zones (65.2%). The lower extremity and pelvic fractures were the most common injury. Associated intra-peritoneal injuries were present in 39.1% patients. An exploratory laparotomy was performed in 58.7% patients (n=27). A high ISS (55.9 versus 35.5, p<0.0001), abnormal coagulation profile (odds ratio [OR] 7.8, 95% confidence interval [CI] 1.974-30.932, p=0.005, and associated chest injuries OR 5.94, 95% CI 1.528-23.19, p=0.014) were independent factors associated with mortality. Multiple musculoskeletal injuries in addition to intra-abdominal injuries and abnormal coagulation are major factors associated with the presence of extensive RH. High ISS, abnormal coagulation, and associated chest injuries are independent factors associated with mortality (Author).
[en] 6 cases of rectus sheath hematoma were correctly diagnosed by ultrasound. 2 cases had bilateral rectus sheath hematoma and 4 cases were unilateral. On ultrasound finding, relatively well defined oval or spindle like cystic mass situated in the area of rectus muscle on all cases. Ultrasound examination may give more definite diagnosis and extension rectus sheath hematoma and also helpful to follow up study of hematoma
[en] Sequenctial ultrasonography was performed after induction of vitreous hematoma in 24 rabbits eyeball to analyze the characteristic sonographic findings of resorbing hematoma. Ultrasonography was done at immediate after inducing hematoma and were followed up at 2nd day, 1st week, 2nd week and 4th week. The result were as follows; 1. In immediate scan after inducing hematoma, multiple sheet-like or linear shaped hematoma was more common than round or diffuse shaped. 2. Size of hematoma was decreased from 2nd day, much more at l1st week, and nearly or completely absorbed at 4th week. 3. Margin of hematoma was blurred from 2nd day and rapidly changed afterward. 4. Even though echogenecity of hematoma in immediate B-mode scan after inducing hematoma showed largely less echogenic than that of retro-orbital fat, hyperechoic and isoechoic cases were also seen. 5. Reflectivity of hematoma, till 2nd day, showed largely over 50% of that of retro-orbital fat, but decreased to the level of below 50%at 1st week, and nearly or completely absorbed at 4th week
[en] The purpose of this study was to assess the technical success rate and adverse events (AEs) associated with ultrasound (US)-guided radiological placement (RP) of a central venous port (CVP) via the subclavian vein (SCV). Between April 2006 and May 2007, a total of 500 US-guided RPs of a CVP via the SCV were scheduled in 486 cancer patients (mean age ± SD, 54.1 ± 18.1 years) at our institute. Referring to the interventional radiology report database and patients' records, technical success rate and AEs relevant to CVP placement were evaluated retrospectively. The technical success rate was 98.6% (493/500). AEs occurred in 26 cases (5.2%) during follow-up (range, 1-1080 days; mean ± SD, 304.0 ± 292.1 days). AEs within 24 h postprocedure occurred in five patients: pneumothorax (n = 2), arterial puncture (n = 1), hematoma formation at the pocket site (n = 2), and catheter tip migration into the internal mammary vein (n = 1). There were seven early AEs: hematoma formation at the pocket site (n = 2), fibrin sheath formation around the indwelling catheter (n = 2), and catheter-related infections (n = 3). There were 13 delayed AEs: catheter-related infections (n = 7), catheter detachments (n = 3), catheter occlusion (n = 1), symptomatic thrombus in the SCV (n = 1), and catheter migration (n = 1). No major AEs, such as procedure-related death, air embolism, or events requiring surgical intervention, were observed. In conclusion, US-guided RP of a CVP via the SCV is highly appropriate, based on its high technical success rate and the limited number of AEs.
[en] To determine the efficacy, safety and primary follow-up results of a guidewire looping technique for the treatment of infrapopliteal arteries. From October 2006 to May 2008, an intraluminal angioplasty of the infrapopliteal arteries was attempted in 200 consecutive patients. Altogether, 417 infrapopliteal lesions, with lengths varying from 2 cm to 32 cm, were treated as part of this study, including 305 lesions in the anterior tibial arteries, 89 in the posterior tibial arteries, and 23 in the peroneal arteries. The 'U'-shaped guidewire technique was attempted in 393 lesions from 361 limbs. The tip of a hydrophilic 0.035-inch guidewire was formed into a 'U' shape with the aid of a 4-Fr catheter and collateral branch vessel to recanalize the completely occluded long segment lesions. A successful angioplasty with at least one artery recanalized directly to the malleolar or dorsal foot was achieved in 322 limbs (89%). The looping technique had a success rate of 90% (352 of 393 lesions). After the procedure, the rest pain was relieved in 58 of 69 patients, while 207 of 245 limbs (85%) showed improvement for intermittent claudication. Complete wound healing was noted in 21 of 54 patients, while 20 of 54 patients showed an improvement in the wound size or depth. A total of 38 major immediate procedure-related complications were noted, including retroperitoneal hematoma, distal emboli, and vessel rupture. The results of this study suggests that the guidewire looping technique is a safe and effective method for the recanalization of the occluded lesions in infrapopliteal vessels
[en] This is the case of a patient presenting with right temporoparietal subacute hematoma secondary to a physical act of aggression. In clinical picture at 24 hours there was predominance of headache of moderate intensity with drowsiness and slight psychomotor restlessness. The skull single radiographies didn't show alterations. Symptoms remained despite the medical treatment, thus a single skull axial tomography was carried out showing the presence of a right temporoparietal subacute epidural hematoma with displacement from the middle line structures. A right temporoparietal craniotomy was carried out to evacuation of the posterior hematoma. Patient evolved satisfactorily with a total recovery as much clinical as imaging. (author)
[en] Objective: To evaluate the safety and efficacy of sonographically guided aspiration of intramuscular, bursal and subcutaneous hematomas. Materials and methods: One hundred eleven interventions were performed in 75 patients at a single institution from January 2005 to December 2009. In all cases the target of interest was identified with ultrasonography. Results: Ninety-six procedures (87.3%) were successful, 14 procedures (12.7%) were unsuccessful due to excessive density and/or viscosity of the content. No significant complications were encountered during or immediately after any procedure. Clinical follow-up records were available for 73 (75%) procedures in 45 (66%) patients, 30 patients did not return for follow-up after hematoma evacuation. No septic or hemorrhagic complications or cases of neurovascular compromise were recorded. Conclusions: Sonographically guided hematoma evacuation is a safe procedure. However, the proportion of unsuccessful evacuations and hematoma recurrence is substantial.
