Post-traumatic intramural duodenal hematoma in children.

BACKGROUND: Intramural duodenal hematoma generates partial or complete obstruction that develops slowly and progressively with a consequent delay in diagnosis. Many diagnostic and therapeutic measures remain debatable and justify a review of current management policy. OBJECTIVES: To highlight the diagnostic and therapeutic steps in pediatric IDH. METHODS: The records of 12 children with post-traumatic IDH who were treated in the Hillel Yaffe Medical Center between 1986 and 2000 were retrospectively reviewed. Three of them had clotting disorders and were excluded. The interval between their admission and diagnosis as well as the therapeutic decisions were evaluated and analyzed. RESULTS: Nine children were treated for IDH. The interval between admission and diagnosis ranged from 24 hours to 6 days. Five children had associated traumatic pancreatitis. Initially, all the children were conservatively treated. In seven the hematoma resolved after 9-20 days. Two children were operated upon because the obstruction failed to resolve. All nine children recovered without permanent complications. CONCLUSIONS: Intramural duodenal hematoma has many clinical and therapeutic puzzling aspects. Bicycle handlebar, road accidents and sports trauma are the main etiologic factors in children, but child abuse should be kept in mind. Associated traumatic pancreatitis is common. Gastroduodenal endoscopy may be useful to clarify doubtful cases. Pediatric surgeons should increase awareness regarding IDH in order to reduce delay in diagnosis and the need for surgical decompression.

Embolization of transected vertebral arteries in unstable trauma patients.

The aim of this paper is to report our experience with coil embolization for the treatment of vertebral artery transection in unstable trauma patients. The course of four patients admitted to our units between 1998 and 2003 with traumatic injuries of the upper thorax or neck is described. All had unstable hemodynamic parameters at presentation. Emergent arteriogram revealed vertebral artery transection, which was managed by immediate coil embolization proximal to the injury site. Initial technical success was achieved in all four patients, with hemodynamic improvement. No further treatment or surgery to control the vessel injury was needed. There were no immediate or late complications of the procedure and no neurological sequelae. Emergency coil embolization is an effective endovascular technique for use in unstable patients with angiography findings of a transected vertebral artery.

Balloon angioplasty of popliteal and crural arteries in elderly with critical chronic limb ischemia.

OBJECTIVE: Elderly patients with extensive infrainguinal peripheral vascular disease and critical chronic limb ischemia (CCLI) are poor surgical candidates. Our purpose was to evaluate angiographic and clinical results of popliteal, infrapopliteal, and multi-level disease percutaneous transluminal angioplasty (PTA) in such patients. DESIGN: Retrospective study of angiographic and clinical files in selected group. MATERIALS AND METHODS: Between 1996 and 2002, 38 elderly patients aged 80-94 years old (mean age 83.3) with critical leg ischemia were treated with PTA. All patients were at high surgical risk. 31/38 (81.5%) patients had chronic non-healing wounds, and 14/38 (37%) had multi-level disease of superficial femoral, popliteal and crural arteries. One hundred and two lesions were treated by angioplasty. Immediate angiographic and 1 year clinical results were retrospectively analyzed. RESULTS: The overall procedural success rate was 32/38 (84.2%). There were three major complications (7.9%), but no deaths, and three technical failures, all were of infrapopliteal lesions. After 1 year, 27 patients could be followed, five patients died during the first year of unrelated causes. Twenty-three patients (85.2%), were clinically re-occluded within 1 year, but complete and partial wound healing was achieved in 80% (16/20) and rest pain improvement in 57% (4/7), so that overall limb salvage was 74% (20/27). CONCLUSIONS: Elderly patients with multi-level CCLI have a short patency term following angioplasty of 14.8% after 1 year. Nevertheless, this temporary vascular patency enables wound healing or improvement in 74% of these patients, thus such endovascular interventions are recommended in this age group.

Uterine artery embolization: a pilot study in a rabbit model.

Eight female adult ex-breeder New Zealand white rabbits underwent bilateral, unilateral, or superselective unilateral uterine artery embolization. The histopathologic changes after embolization in New Zealand white rabbits resemble those in humans, making rabbits an appropriate model for experimental uterine artery embolization.

Use of peripheral cutting balloon in the management of resistant benign ureteral and biliary strictures.

PURPOSE: To report the initial and midterm results of percutaneous cutting balloon incision and dilation (PCBID) for the treatment of benign ureteral and biliary strictures in patients after failed high-pressure balloon dilation. MATERIALS AND METHODS: The study sample consisted of 11 patients: three with ureteric strictures after renal transplantation, three with biliary anastomotic strictures after liver transplantation, three with pelvic metastatic disease compressing the ureter, one after a failed endoscopic papilla of Vater sphincterotomy, and one with tight stenosis at the choledochojejunal anastomosis. All strictures were resistant to high-pressure balloon dilation. Four patients underwent PCBID immediately after failed high-pressure balloon dilation in the same session, and seven underwent the procedure in a separate session within the subsequent week. The width of the peripheral cutting balloons did not exceed the diameter of the normal lumen (7-8 mm). RESULTS: PCBID was successful in nine patients (82%). One failure occurred in a transplanted ureter and one occurred in a transplanted liver with a choledochocholedochal anastomosis. In both cases, PBCID was performed in the same session as failed high-pressure balloon dilation. There were no periprocedural complications. Patency was confirmed at the 3- and 6-month clinical and ultrasonographic follow-up. CONCLUSION: PCBID is a simple minimally invasive method for the treatment of benign ureteric and biliary strictures. The success rate is high and no complications occurred.

Transhepatic balloon dilatation of early biliary strictures in pediatric liver transplantation: successful initial and mid-term outcome.

PURPOSE: To evaluate the initial and mid-term outcomes of transhepatic balloon dilatation for the treatment of early biliary strictures in lateral left-segment liver transplants in young children. METHODS: Between April 1997 and May 2001, seven children aged 9 months to 6 years with nine benign strictures in left-segment liver grafts were treated percutaneously. Sessions of two or three dilations were performed three or four times at average intervals of 10-20 days. In each session, the biliary stenoses were gradually dilated using balloons of 3-7 mm. Follow-up ranged from 12 to 54 months (mean 27 months, median 12 months). Clinical success was defined as resolution of the stenosis, normalization of liver enzymes and lack of clinical symptoms RESULTS: Technical success was achieved in all nine strictures. Hemobilia occurred in one patient and was successfully treated. On follow-up, all patients had complete clinical recovery with normalization of liver function and imaging of patent bile ducts. CONCLUSION: Balloon dilatation is an effective and relatively safe method for the treatment of early biliary strictures in left-segment liver transplantation in young children. We recommend this approach as the initial treatment for early strictures. Metal stents or surgery should be reserved for patients with late appearance of strictures or failure of balloon dilatation.

Mesh wrap in severe pediatric liver trauma.

PURPOSE: This study reviews the authors' experience in treating severe pediatric liver injuries with absorbable mesh wrapping. The authors found this relatively new therapeutic method very useful in selected cases, although its use is not very common in children. The authors analyze the indication describe some technical aspects, and discuss the advantages and the pitfalls of the method. METHODS: In a 10-year period between 1990 and 2000, 181 children were admitted to Hillel-Yaffe Medical Center with blunt hepatic trauma. A total of 132 children were treated conservatively, and 49 (27%) were operated on. The operated group included 35 cases of isolated liver injuries and 14 cases of additional intraabdominal injuries. Thirty-four children were operated on between 1990 and 1995 (36% of 96 children), whereas between 1995 and 2000, 15 children were operated on (17% of 85 children), including 4 children aged 18 months to 15 years with massive liver bleeding who were treated with mesh wrap technique. The retrospective analysis of these 4 cases indicates a progressive policy in the recognition of cases suitable for mesh wrapping and gallbladder conservation. RESULTS: The perihepatic mesh wrap technique controlled the bleeding in all children. In 3 of them the right lobe was wrapped, and, in 1 case, total liver wrapping was performed. Hepatic enzymes and bilirubin levels were elevated in the first 3 to 7 days and declined gradually to normal levels. The perihepatic mesh was not an obstacle to a transcutaneous drainage of an intrahepatic biloma. All 4 children returned to normal physical activities. CONCLUSIONS: Liver mesh wrap is a simple, effective, and rapid way to obtain hemostasis and to conserve parenchyma in severe traumatized liver. The decision to wrap the liver should be done early to prevent acidosis and hypothermia. Cholecystectomy is not an integral part of the procedure in children. The morbidity is low, and most of the complications can be treated nonsurgically.

Ovarian varices in healthy female kidney donors: incidence, morbidity, and clinical outcome.

OBJECTIVE: Kidney donation is associated with ligation of the ovarian vein and is comparable to ovarian vein embolization. We evaluated the incidence, morbidity, and clinical outcome of ovarian varices in healthy female kidney donors before and 6 months after nephrectomy. MATERIALS AND METHODS: Between 1994 and 2001, 273 healthy female kidney donors underwent preoperative abdominal aortography. The study group consisted of 27 women (9.9%) in whom retrograde flow in an incompetent left ovarian vein was noted during the venous phase of imaging. All patients underwent left nephrectomy with left ovarian vein ligation. Only women with retrograde flow in the left ovarian vein were asked to complete a questionnaire about the incidence and intensity of pelvic pain before and 6 months after nephrectomy. RESULTS: Twenty-two of the 27 left-kidney donors with retrograde flow in the ovarian vein were available for follow-up. Thirteen (59%) of those 22 reported chronic pelvic pain. After nephrectomy, the pelvic pain completely resolved in seven (54%), improved in three (23%), and persisted in three (23%). CONCLUSION: Our study found a 9.9% prevalence of ovarian varices in the general population. Our findings suggest that more than half (59%) the patients with ovarian varices have pelvic congestion syndrome and that most (77%) of them might benefit from ovarian vein embolization or ligation.
