We studied the changes in proximal embolization of the splenic artery to the intraparenchymal blood flow with Doppler ultrasound.
Seventeen trauma patients with spleen injury OIS grade 2–5 underwent embolization of the splenic artery. Peak-systolic velocity
(PSV) and end-diastolic velocity (EDV) were measured in intrasplenic arteries initially 1 day after embolization, at early
follow-up after 7 days, at intermediate follow-up after 10 weeks, and at late follow-up after 10 months. Resistance index
(RI), systolic/diastolic ratio (S/D ratio), acceleration (AC), and acceleration time (AT) were calculated. The results were
compared to values from 17 volunteers. RI increased from 0.39 initially to 0.49 (P = 0.002) at intermediate and to 0.52 (P < 0.001) at late follow-up. S/D ratio increased from 1.68 initially to 1.99 (P = 0.002) and to 2.10 (P < 0.001) at intermediate and late follow-up, respectively. Follow-up results of RI and S/D ratio differed significantly from
the reference group. AC increased from 1.06 m/s2 initially to 1.89 m/s2 at late follow-up (P = 0.01). AC at late follow-up was not different from reference group (2.33 m/s2). In conclusion, Doppler ultrasound is a useful tool in the evaluation of improvable intraparenchymal blood flow over time
after central splenic artery embolization. 相似文献

The purpose of this study was to report case studies of iatrogenic splenic injuries on computed tomography (CT) in symptomatic
postsurgical patients. The medical records and CT studies of all patients with injury to the spleen after abdominal surgery
were reviewed. CT was performed in the postoperative period, urgently in all patients. Unsuspected splenic injuries were found
on CT performed in the early postoperative period in seven symptomatic patients (five women and two men, age range 21–81 years)
after various abdominal surgical procedures. Injuries as detected on CT included splenic infarct in five, subcapsular hematoma
in two, and laceration of the spleen in one. These findings were the only abnormal abdominal findings in four of the patients
and were probably the source of the postoperative abdominal pain and fever. Splenic injury is a rare complication of abdominal
surgery. It is often the radiologist who diagnoses the injury, and awareness of this possible complication can obviate further
investigations. 相似文献

目的 观察二甲基亚砜(DMSO)、透明质酸酶(HAase)不同用药方法对多西紫杉醇外渗性皮肤损伤大鼠的疗效.方法 30只SD大鼠随机分为6组,每组5只,每只大鼠双后肢造成多西紫杉醇血管外渗模型后,分别外涂DMSO、局部注射HAase、HAase局部注射联合DMSO外涂、外涂生理盐水(NS)、局部注射NS及模型对照组不作任何防治干预.观察各组大鼠多西紫杉醇外渗性损伤程度和损伤愈合时间.结果 各组大鼠损伤程度有差异,其中DMSO组、HAase组及联合用药组的损伤程度较轻,NS外涂组、NS注射组和模型对照组的损伤程度较重.DMSO组的损伤愈合时间为19.10±2.13天,显著短于NS外涂组23.70±2.41天和模型对照组25.70±2.26天(P<0.01).HAase组和HAase联合DMSO组的损伤愈合时间为12.00±3.00天和14.40±2.30天,显著短于其他4组的愈合时间(P<0.01),但该两组间无显著性差异.结论 DMSO外涂或HAase单独局部注射均可降低多西紫杉醇外渗性损伤程度,缩短损伤愈合时间,具有良好的疗效.联合用药未能提高疗效. 相似文献

Splenic angiosarcoma (SA) is a rare disease that can cause spontaneous splenic rupture leading to unexpected death. The rare incidence and non-specific clinical presentations made the early correct diagnosis of SA impossible in clinical practice. Even with medical intervention, 80% of patients died within 6 months after diagnosis. Here, we report a man who had complained of abdominal distension for 2 weeks and succumbed to the disease nine hours after admission. Diagnosis of hepatic and splenic angiosarcomas was based on post-mortem histopathological examination and immunohistochemistry, and the cause of death was hemorrhagic shock caused by spontaneous splenic rupture secondary to SA. This present case was the first forensic autopsy of spontaneous splenic rupture secondary to SA, which can highlight the diagnosis of rare diseases in forensic practice, and forensic pathologists should bear in mind these rare diseases even in routine practice. 相似文献

The objective of this study was to determine the clinical and management implications of the finding of active extravasation
in blunt or penetrating trauma patients evaluated with abdomino-pelvic computed tomography (CT) using 64MDCT technology. This
HIPAA compliant, retrospective study was IRB-approved, and the need for consent was waived. All adult patients scanned with
64MDCT who sustained blunt or penetrating abdomino-pelvic trauma and had findings of active extravasation at our Level I trauma
center during a 30-month period were included. Two radiologists reviewed all abdomino-pelvic CT scans and characterized the
active hemorrhage by location, extent, and attenuation on all available phases of imaging. Subsequent therapy and disposition
were determined by reviewing the patients’ medical records. The relationship between the location of a source of extravasation
and subsequent clinical outcome was evaluated using Fischer’s exact test. The relationship between the size and attenuation
of the active hemorrhage and patient outcome were compared using the Wilcoxon rank sum test. One hundred and twenty-five patients
with active extravasation were included. Patients with solid organ or pelvic injuries that were managed conservatively or
had a negative digital subtraction angiogram had statistically significant smaller areas of active extravasation when compared
to those that required intervention or died. When the attenuation values of extravasation are normalized to the intravascular
attenuation achieved after intravenous contrast injection, no significant differences were seen based on subsequent clinical
outcome. Based on location, those patients with solid organ, gastrointestinal/mesenteric, and pelvic sources of bleeding showed
statistically significant higher likelihood of requiring subsequent intervention or dying, compared with those patients with
subcutaneous, intramuscular, or retroperitoneal sources of active extravasation who were more likely to be managed conservatively
(p < 0.0001, p = 0.005, p = 0.006, respectively). In blunt and penetrating trauma patients evaluated using 64MDCT technology, the location and size
of the region of active extravasation are predictive of the type of subsequent clinical management. Normalized attenuation
values of the active extravasation, however, are not predictive of subsequent management. 相似文献

Summary A case of intracerebral extravasation of contrast medium is reported. In cases of head injury this occurrence is rare and is manifested by persistent images on both frontal and lateral views of the angiogram. This indicates severe cerebral trauma with active hemorrhage and the prognosis is generally bad. A possible mechanism seems to be contrecoup. 相似文献

目的探讨超声动态监测在外伤性脾破裂非手术治疗中的应用价值。方法对25例外伤性脾破裂患者进行非手术治疗,超声动态监测重点观察脾脏回声和腹腔积液等情况,并严密监测临床体征。结果 25例患者中诊断为真性脾破裂14例,中央性脾破裂5例,包膜下脾破裂6例;首次超声检查确诊16例,经超声动态监测确诊9例。其中22例患者经非手术治疗成功,超声复查提示脾内血肿缩小或基本吸收,腹腔积液减少或消失;3例患者经超声动态监测后确认非手术治疗无效而中转急诊手术。结论超声动态监测脾内损伤情况及腹腔内积血的变化,能直观、实时地显示外伤性脾破裂非手术治疗中的病情进展情况;早期阶段实施床边超声检查有助于提高非手术治疗的成功率,而对可疑者进行超声动态监测则有助于尽早确诊。综合临床体征观察和超声动态监测可作为外伤性脾破裂非手术治疗的首选监测手段。 相似文献

目的评价多层螺旋CT对外伤性脾破裂的诊断准确性。方法 55例由临床与手术证实的外伤性脾破裂患者均经多层螺旋CT(MSCT)平扫,其中20例又经对比增强CT扫描。对所有患者的CT表现进行了回顾性分析。结果在55例中,起初CT平扫正确诊断50例(90.9%)外伤性脾破裂。增强扫描的20例全部(100%)得到正确诊断。在CT平扫像上,外伤性脾破裂主要表现为脾脏肿大、形态不规则、密度不均匀、边缘模糊及弧形高密度影,而CT增强扫描显示了脾脏内或表面不规则撕裂口、脾内未强化血肿及假性动脉瘤形成。49例(89.1%)患者伴发腹腔积液。早期或轻微脾破裂时,腹腔积液主要见于左侧结肠旁沟及道格拉斯窝。38例(69.1%)患者合并其他脏器或组织损伤。结论多层螺旋CT在外伤性脾破裂的诊断中,具有安全、快速、准确率高等优势。在患者病情许可的条件下,对比增强扫描可提高诊断准确率及合并症的检出率,并能正确分型,为临床选择治疗方案提供可靠依据。 相似文献

Purpose To study the value of partial splenic embolization (PSE) for the treatment of hypersplenism in patients undergoing embolization
of hepatocellular carcinoma (HCC).
Methods Transcatheter hepatic arterial embolization (THAE) combined with PSE was performed in 30 patients with HCC complicating liver
cirrhosis, portal hypertension, and hypersplenism. Gelfoam sponge was used as the embolic material for PSE and limited to
100–150 pieces.
Results More than 50% of splenic parenchyma was infarcted in 27 patients. Leukopenia and thrombocytopenia were corrected by PSE in
25 of 27 patients with hypersplenism. In 26 patients with esophageal varices, including 5 patients with bleeding, no rebleeding
occurred during a 6–17 month follow-up. Hypersplenism was not corrected in 2 of 3 patients whose infarcted splenic parenchyma
was less than 50%. No splenic abscesses or other severe complications were observed. Of the 30 patients treated, 19 are still
alive after 1 year.
Conclusions THAE combined with PSE is a safe and effective measure for patients with HCC. 相似文献
