多层螺旋CT血管成像诊断颈动脉海绵窦瘘

目的探讨颈动脉海绵窦瘘(CCF)的解剖病理基础及螺旋CT血管成像(MSCTA)表现,提高MSCTA对CCF的诊断能力。方法12例经DSA证实的CCF均进行了螺旋CT平扫、增强扫描及血管成像重建。结果CCF的MSCT及CTA表现为:海绵窦扩大及眼上静脉扩张12例,并与颈内动脉同时显影;其他属支静脉扩张6例;对侧海绵窦扩大4例,与DSA检查结果一致。患侧眼球突出12例。颅底、眶壁骨折5例。眼球壁模糊、增厚5例。脑挫伤、出血4例。眼外肌增粗1例。结论螺旋CT及其血管成像诊断CCF简单、快捷、准确、可靠,特别是在外伤性CCF中,是首选的检查及诊断方法。     

MAGNETIC RESONANCE IMAGING FACILITATES ASSESSMENT OF PERIANAL CROHN'S DISEASE

Three illustrative cases of magnetic resonance imaging (MRI) in patients with perianal Crohn's disease are presented. Modern MRI techniques provided excellent visualization of perineal anatomy, inflammatory tissues and an anorectal stricture. It also allowed detailed delineation of the patho-anatomy of fistulous abscess and any communication to more proximal bowel. This report illustrates the potential of modern MRI as an important investigative adjunct in evaluating the anorectal manifestations of Crohn's disease.

Ano-cutaneous flap repair for complex and recurrent supra-sphincteric anal fistula.

BACKGROUND: Suprasphincteric fistulae remain the most difficult to cure. OBJECTIVES: The purpose of this study was to evaluate the healing rate of suprasphincteric anal fistula treated by ano-cutaneous advancement flap repair, and the impact of this procedure on continence and quality of life. METHOD: Sixteen patients with complex, recurrent or chronic suprasphincteric fistulae associated with significant tissue damage (necrotizing fasciitis, keyhole deformity and anal stenosis) or who had failed previous surgical procedures were treated by ano-cutaneous flap closure. They were assessed pre and postoperatively by the treating surgeon for wound healing and fistula recurrence and later followed up by phone interview using the St Mark's Hospital incontinence score and the Perianal Disease Activity Index (PDAI) as indicators of treatment outcome. RESULTS: Fifteen patients had successful healing of their fistula with the cutaneous flap, with recurrence in only one. The most common short-term complications were minor graft site wound separation, which healed in all cases without intervention, and wound pain, which settled over time and was not associated with recurrence. Continence improved for almost 70% of the patients, with a significant reduction in St Mark's incontinence scores (t = 2.62, 15 d.f., P = 0.02). PDAI also decreased significantly (t = 7.55, 15 d.f., P < 0.001), demonstrating improvement in quality of life for most patients. CONCLUSION: Ano-cutaneous flap can achieve healing of complex and recurrent suprasphincteric anal fistula in patients who had previously failed at other forms of treatment thus improving their quality of life and continence.

Most cases of anal abscess are caused by anal fistula and invasion of the surrounding tissues by a mixed colonic flora. Treatment consists of excision of the abscess and, in case of fistula, fistulectomy. Primary anorectal and perianal forms of actinomycosis are very rare and caused by actinomyces, as ubiquitous anaerobics bacterium. We report a case of perianal actinomycosis. The patient had a short history of painless perineal induration without fever and leukocytosis with normal results at routine blood examination. After excision, sulfur granules drained from the cavity and pathological investigations indicated perianal actinomycosis. Appropriate surgery and antibiotic treatment healed the perianal infection. After exclusion of possible diagnoses such as Crohn’s disease, tuberculosis and malignant growths, the rare case of perianal actinomycosis should be considered in the differential diagnosis of painless perianal masses.

经未显影的岩下窦途径栓塞海绵窦区硬脑膜动静脉瘘

目的探讨经未显影的岩下窦途径栓塞海绵窦区硬脑膜动静脉瘘(CSDAF)的治疗方法。方法回顾性分析7例CSDAF病人的临床资料,均经未显影的岩下窦插管,以微弹簧圈栓塞海绵窦和瘘口。结果5例插管成功并达到完全致密栓塞;2例导管虽插入海绵窦,但海绵窦分隔致导管位置与瘘口不相通,而改行面静脉-眼静脉途径插管行栓塞治疗。7例病人均治愈,随访5～20个月,均无复发。结论经岩下窦途径栓塞是CSDAF最常用的治疗方法,即使岩下窦未显影,也有相当部分病人可插管和治疗成功。     

Sentinel Bleeding After Pancreaticoduodenectomy: A Disregarded Sign

Introduction Delayed massive hemorrhage induced by pancreatic fistula after pancreaticoduodenectomy is a rare but life-threatening complication. The purpose of this study was to analyze the clinical course of patients with late hemorrhage, with or without sentinel bleeding, to better define treatment options in the future. Material and Methods From April 1998 to December 2006, 189 pancreaticoduodenectomies were performed. Eleven patients, including two patients referred from other hospitals, were treated with delayed massive hemorrhage occurring 5 days or more after pancreaticoduodenectomy. Sentinel bleeding was defined as minor blood loss via surgical drains or the gastrointestinal tract with an asymptomatic interval until development of hemorrhagic shock. The clinical data of patients with bleeding episodes were analyzed retrospectively. Results Eight of the 11 patients had sentinel bleeding, and seven of them had it at least 6 h before acute deterioration. Seven out of 11 patients died, five out of eight with sentinel bleeding. No differences could be detected between patients with or without sentinel bleeding before delayed massive hemorrhage. The only difference found was that non-surviving patients were significantly older than surviving patients. Delayed massive hemorrhage is a common cause of death after pancreaticoduodenostomy complicated by pancreatic fistula formation. The observation of sentinel bleeding should lead to emergency angiography and dependent from the result to emergency relaparotomy to increase the likelihood of survival.     

创伤性肾动静脉瘘的介入治疗

目的 评价用介入技术治疗创伤性肾动静脉瘘(RAVFs)的安全性和疗效。方法 对8例不适宜做外科治疗的RAVFs患者进行了介入治疗，其中外伤性损伤4例，医源性损伤4例。6例行经导管超选择性肾动脉内钢丝圈栓塞术，2例行被覆膜支架置入患侧肾动脉内封闭瘘口。结果 血管造影显示肾内型动静脉瘘4例，累及肾动脉段-亚段级分支；主干(肾外)型动静脉瘘4例。治疗均获成功，治疗结束时复查血管造影显示瘘口被封闭。轻微并发症1例。医源性RAVFs患者术后失血症状迅速改善，肉眼血尿消失；4例术前存在心脏负荷过度症状患者，闭塞动静脉瘘后症状迅速改善，血管杂音消失。术后肾功能测定均属正常范围，其中2例肾动脉被覆膜支架置入患者，同位素肾扫描显示患侧肾脏形态、功能正常。术后随访10～42个月，2例分别于术后10，18个月死于与RAVFs无关的疾病。6例仍然生存，一般情况良好，未再针对RAVFs进行外科或介入治疗。结论 介入技术，包括经导管超选择性肾动脉内栓塞术和被覆膜支架置入术，是治疗创伤性、复杂型RAVFs的安全、有效的方法。
