Abstract
PURPOSE To evaluate incidence and characteristics of arterial thromboembolic complications in critically ill children. MATERIALS AND METHODS Hospital records of all consecutive patients with arterial thromboembolic events (ATEs) occurring in the pediatric intensive care unit (PICU) from January 1997 to August 2001 were reviewed. Data collected included demographics and location, treatment modalities and outcome of ATEs. RESULTS Fifty-four ATEs in 51 children (median age, 14 days) were identified, reflecting an incidence of 1.2% of all PICU patients. Arterial thromboembolic events were located in peripheral arteries in 52 (96%) cases and were associated with indwelling arterial catheters (n=26) or cardiac catheterization (n=26). The remaining 2 ATEs were located in the left ventricle and cerebral arteries, respectively. Therapy consisted of heparin (n=51), thrombolysis (n=22), oral anticoagulation (n=12), and aspirin (n=34). Complete resolution was noted in 33 (70%), partial resolution in 10 (21%), and no resolution in 4 (8.5%) cases. Bleeding complications occurred in 1 patient treated with heparin and in 12 (54%) of the 22 patients receiving thrombolytic therapy. CONCLUSIONS Arterial thromboembolic events are frequent complications of PICU, particularly affecting neonates, and mostly associated with catheters. Studies to determine safe and effective prophylactic and treatment modalities of ATEs in children are required.

Abstract
PURPOSE We sought to review the diagnosis and treatment of children with lower extremity vascular injury. METHODS We performed a query of our vascular surgery database from 1996 through 2002 to determine those with lower extremity vascular injuries requiring surgery who were also less than 13 years of age. Patient demographics, presentation, cause, surgical specifics, and outcome were sought. RESULTS Six children (2 girls and 4 boys) with an average age of 6.8 years (range, 2-9 years) were found. The causes were 3 blunt injuries, 2 iatrogenic injuries, and 1 penetrating injury. Associated injuries were common. There were 3 femoral and 3 popliteal artery injuries. Two were pseudoaneurysms (common femoral and popliteal artery), and 4 were acute occlusions, of which 3 experienced a delay in diagnosis. There was one primary below-knee amputation. Four reverse vein bypasses were performed, and one vein patch repair of a pseudoaneurysm was performed. Generally, 7 to 9 O interrupted Prolene (Ethicon, Inc, Somerville, NJ) repairs were performed. A delay in diagnosis (2 blunt injuries) resulted in 2 major amputations and 1 insensate foot. Four reconstructions are functioning with viable limbs (follow-up, 5-49 months). An associated brain injury resulted in the only death. CONCLUSIONS Vascular blunt injury is especially insidious in children. However, an aggressive approach of vascular repair, even extensive bypasses with reverse vein, will allow limb salvage in the absence of a diagnostic delay.

Abstract
This article about antithrombotic therapy in children is part of the 7th American College of Chest Physicians Conference on Antithrombotic and Thrombolytic Therapy: Evidence-Based Guidelines. Grade 1 recommendations are strong and indicate that the benefits do, or do not, outweigh the risks, burden, and costs. Grade 2 suggests that individual patients' values may lead to different choices (for a full understanding of the grading see Guyatt et al, CHEST 2004; 126:179S-187S). Among the key recommendations in this article are the following. In neonates with venous thromboembolism (VTE), we suggest treatment with either unfractionated heparin or low-molecular-weight heparin (LMWH), or radiographic monitoring and anticoagulation therapy if extension occurs (Grade 2C). We suggest that clinicians not use thrombolytic therapy for treating VTE in neonates, unless there is major vessel occlusion that is causing the critical compromise of organs or limbs (Grade 2C). For children (ie, > 2 months of age) with an initial VTE, we recommend treatment with i.v. heparin or LMWH (Grade 1C+). We suggest continuing anticoagulant therapy for idiopathic thromboembolic events (TEs) for at least 6 months using vitamin K antagonists (target international normalized ratio [INR], 2.5; INR range, 2.0 to 3.0) or alternatively LMWH (Grade 2C). We suggest that clinicians not use thrombolytic therapy routinely for VTE in children (Grade 2C). For neonates and children requiring cardiac catheterization (CC) via an artery, we recommend i.v. heparin prophylaxis (Grade 1A). We suggest the use of heparin doses of 100 to 150 U/kg as a bolus and that further doses may be required in prolonged procedures (both Grade 2 B). For prophylaxis for CC, we recommend against aspirin therapy (Grade 1B). For neonates and children with peripheral arterial catheters in situ, we recommend the administration of low-dose heparin through a catheter, preferably by continuous infusion to prolong the catheter patency (Grade 1A). For children with a peripheral arterial catheter-related TE, we suggest the immediate removal of the catheter (Grade 2C). For prevention of aortic thrombosis secondary to the use of umbilical artery catheters in neonates, we suggest low-dose heparin infusion (1 to 5 U/h) (Grade 2A). In children with Kawasaki disease, we recommend therapy with aspirin in high doses initially (80 to 100 mg/kg/d during the acute phase, for up to 14 days) and then in lower doses (3 to 5 mg/kg/d for > or = 7 weeks) [Grade 1C+], as well as therapy with i.v. gammaglobulin within 10 days of the onset of symptoms (Grade 1A).

Abstract
An acutely ischaemic lower limb following femoral artery cannulation in children is a problem infrequently encountered by plastic surgeons in the UK. When such a case presented to us, we performed a search of published literature to guide us to the optimum treatment. This included methods for extraperitoneal exposure of the common iliac artery and vein. We describe the surgical technique that we used to salvage an acutely ischaemic lower limb following femoral puncture and a review of the literature.

Abstract
Infection of the hip joint can cause severe articular damage. Standard treatment of septic arthritis includes surgical débridement and intravenous antibiotics. Options for definitive management in the presence of joint destruction include excision arthroplasty, arthrodesis, and total hip arthroplasty. Two cases of septic arthritis of the hip as a complication of femoral artery cannulation are presented. These cases highlight a potential complication that may not be readily appreciated by clinicians who routinely perform femoral vascular cannulation. After all evidence of ongoing infection had disappeared, both cases ultimately were treated with total hip arthroplasty. Both patients have improved function and pain at 2.5 and 5 years of follow-up. Given the frequency with which femoral intravascular catheters are used in numerous procedures, methods of avoiding infection of the hip joint must be implemented. These 2 cases emphasize the potential risks of these procedures and show management with total hip arthroplasty.

Abstract
PURPOSE This study evaluated the risk factors and surgical management of complications caused by femoral artery catheterization in pediatric patients. METHODS From January 1986 to March 2001, the hospital records of all children who underwent operative repairs for complications caused by femoral artery catheterization were reviewed. A prospective cardiac data bank containing 1674 catheterization procedures during the study period was used as a means of determining risk factors associated with iatrogenic femoral artery injury. RESULTS Thirty-six operations were performed in 34 patients (age range, 1 week-17.4 years) in whom iatrogenic complications developed after either diagnostic or therapeutic femoral artery catheterizations during the study period. Non-ischemic complications included femoral artery pseudoaneurysms (n = 4), arteriovenous fistulae (n = 5), uncontrollable bleeding, and expanding hematoma (n = 4). Operative repairs were performed successfully in all patients with non-ischemic iatrogenic femoral artery injuries. In contrast, ischemic complications occurred in 21 patients. Among them, 14 patients had acute femoral ischemia and underwent surgical interventions including femoral artery thrombectomy with primary closure (n = 6), saphenous vein patch angioplasty (n = 6), and resection with primary anastomosis (n = 2). Chronic femoral artery occlusion (> 30 days) occurred in seven patients, with symptoms including either severe claudication (n = 4) or gait disturbance or limb growth impairment (n = 3). Operative treatments in these patients included ileofemoral bypass grafting (n = 5), femorofemoral bypass grafting (n = 1), and femoral artery patch angioplasty (n = 1). During a mean follow-up period of 38 months, no instances of limb loss occurred, and 84% of children with ischemic complications eventually gained normal circulation. Factors that correlated with an increased risk of iatrogenic groin complications that necessitated surgical intervention included age younger than 3 years, therapeutic intervention, number of catheterizations (>or= 3), and use of 6F or larger guiding catheter. CONCLUSION Although excellent operative results can be achieved in cases of non-ischemic complications, acute femoral occlusion in children younger than 2 years often leads to less satisfactory outcomes. Operative intervention can provide successful outcome in children with claudication caused by chronic limb ischemia. Variables that correlated with significant iatrogenic groin complications included a young age, therapeutic intervention, earlier catheterization, and the use of a large guiding catheter.

Abstract
OBJECTIVE Limb length discrepancies (LLDs) in growing children may accompany extremity arterial occlusions. Revascularization with vein grafts has been questioned because of degenerative graft changes observed at other sites. This study was undertaken to define vein graft durability and efficacy in lower extremity revascularizations in preadolescent children. STUDY DESIGN Fourteen children (10 boys, 4 girls) with a mean age of 7.3 years (range, 2-11 years) who underwent 16 lower extremity revascularizations with greater saphenous vein grafts were subjected to follow-up with graft ultrasonography, ankle/brachial indices (ABIs) with and without exercise, and limb length determinations. A mean of 5.7 years elapsed between the onset of ischemia and operation. Arterial occlusions resulted from cardiac catheterizations (11), arteritis (1), dialysis cannulation (1), and penetrating trauma (1). Indications for operation included LLD (6), claudication (4), both LLD and claudication (3), markedly diminished ABIs with a potential for LLD (2), and a traumatic transection with hemorrhage (1). The reconstructions with 15 reversed and one in situ vein grafts included iliofemoral (11), femorofemoral (1), aortofemoral (1), femoropopliteal (1), popliteal-popliteal (1), and popliteal-posterior tibial (1) arterial bypass grafts. RESULTS Among patent grafts available for follow-up, 36% (5 of 14) remained unchanged, 50% (7 of 14) developed nonaneurysmal dilatation, and 14% (2 of 14) exhibited nonprogressive aneurysmal expansion. One graft became occluded, and one graft was lost to follow-up. Collectively, the grafts manifest an 11.2% expansion at an average of 10.7 years postoperatively. ABIs increased from 0.75 preoperatively to 0.97, at an average of 11.0 years postoperatively. LLDs were reduced from 1.66 to 1.24 cm, at an average of 11.4 years postoperatively. CONCLUSION Vein graft reconstructions of lower extremity arteries in preadolescent children are durable. They provide an efficacious means of restoring normal blood flow, and in 70% of children their preexisting LLDs were reduced.

Abstract
OBJECTIVE AND IMPORTANCE For neonates requiring cerebral endovascular procedures, an alternative route of arterial access, the umbilical artery, is described. Transfemoral catheterization, with its attendant risks, can thus be avoided. CLINICAL PRESENTATION Six neonates with severe cardiac failure secondary to aneurysmal malformations of the vein of Galen underwent transarterial embolization in an effort to reduce flow through the intracranial arteriovenous malformations and therefore improve control of the high output cardiac failure. TECHNIQUE The transumbilical route was used in each case, with successful devascularization of some of the malformations in all patients. The femoral arteries were preserved for future staged embolizations. No complications related to the umbilical artery catheterization were encountered. CONCLUSION Femoral artery cannulation in neonates is technically challenging and may result in stenosis or thrombosis of the vessel. The umbilical artery provides an alternative route of vascular access for cerebral artery catheterization and embolization in these patients, preserving the femoral arteries for future interventions.

Abstract
BACKGROUND Abnormalities of arterial pulse and limb growth after retrograde femoral arterial catheterization have been well documented. However, the magnitude of such complications after transfemoral artery balloon dilatation has not been thoroughly investigated. This study sought to evaluate the prevalence of these abnormalities in children who have undergone transfemoral artery balloon dilatation. METHODS AND RESULTS Data on 43 consecutive patients (1 day to 15.5 years old at the time of balloon dilatation) seen on follow-up (42 +/- 23 months) (group 1) were compared with those of 35 patients undergoing retrograde femoral arterial catheterization (group 2) and 47 control patients. Interventional ankle/control ankle blood pressure index (AAI), ratio of interventional/control lower limb length (LLI), and leg length difference (LLD) were measured. Ages and weights at study were similar in all three groups, as were the ages and weights at intervention and duration of follow-up in groups 1 and 2. The AAI was lower (P = .023) in group 1 (0.95 +/- 0.13) than in groups 2 (1.0 +/- 0.1) and 3 (1.01 +/- 0.09). The prevalence of subjects with AAI < or = 0.9 was higher (P = .003) in group 1 than in the other two groups. The LLI and LLD were similar (P > .1) in all three groups. AAI and LLD in the balloon group are not significantly associated with age and weight at intervention, duration of follow-up, or size of the balloon or balloon catheter shaft. CONCLUSIONS Transfemoral artery balloon dilatation procedures produce superficial femoral artery compromise, but there was no significant limb growth retardation at a 3.5-year mean follow-up, which may be related to development of collateral circulation. Study of a larger number of children at a longer follow-up interval may be necessary to further confirm these observations.

Abstract
UNLABELLED Vascular trauma from accidental or iatrogenic causes is becoming more common in children. In early infancy, the most common arterial injuries are caused by diagnostic or interventional cardiac catheterizations. Doppler arterial pressure measurements and the computed ankle-brachial pressure index (ABI) are the most helpful diagnostic modalities in the assessment and follow-up of the ischemic extremity. Because normative ABI data in small children are not available, an ABI of 0.9 or less (based on data obtained from an adult population), is used to indicate limb ischemia in young infants. The purpose of this study was to define the normal values of ABI in newborns and infants. MATERIALS AND METHODS Three hundred and fifty patients were divided into two groups: group 1 (n = 200; male-to-female ratio, 1:1) were full-term (gestational age 40 +/- 1.3 weeks, surface area 0.22 +/- 0.02 m2) healthy newborns following uneventful pregnancy and delivery. Group 2 (n = 150) were healthy patients aged 2 weeks to 2.5 years admitted for elective hernia repair. All the patients underwent a complete physical examination, which excluded any cardiovascular pathology. The systolic blood pressure (BP) was measured bilaterally over the brachial, tibialis posterior, and dorsalis pedis arteries. All BP data were obtained in the supine position, using an ultrasonic Doppler flow detector, an appropriately-sized pneumatic cuff and a sphygmomanometer. The chosen cuff size was long enough to completely encircle the circumference and wide enough to cover 75% of the length of the upper arm. The same cuff was applied around the ankle above the malleoli. BP values were expressed as mean +/- SD in mm Hg. If there was a difference between the BP in the two arms, the higher pressure was used for calculation of the ABI. RESULTS The BP measurements in newborns (group 1) were left brachial, 98 +/- 11; right brachial, 90 +/- 10 (P < .001), left and right tibialis posterior and left and right dorsalis pedis were 83, 81, 84, and 82 mm Hg, respectively. The mean computed ABI was 0.88 +/- 0.11. Fifty eight percent of the newborns had an ABI less than 0.9 (lower limit of normal in adults). The ABI values in patients belonging to group 2 increased with age and surface area. The mean ABI was 1.0, 1.1, and more than 1.1 in patients aged, 1, 1.5, and 2 years with surface areas of 0.4, 0.5 and 0.6 m2, respectively (P < .001 compared with group 1). CONCLUSION The normative ABI in newborns and infants is significantly lower than in older children and reaches normal (adult) values during the second year of life. These data may be used as a reference when assessing lower extremity ischemia caused by trauma in young patients.

Abstract
PURPOSE The purpose of this study was to determine the contribution of blunt vascular trauma to death and disability in children. METHODS We reviewed the medical records of 41 patients aged 17 years and younger requiring operative intervention for 48 blunt vascular injuries during the past 18 years. RESULTS Eight patients had arterial injuries (seven brachial, one superficial femoral) associated with orthopedic trauma resulting from falls. All eight were associated with a pulse deficit and were easily recognized. None of the eight had late sequelae after vascular repair. Thirty-three patients had vascular trauma as a result of motor vehicle crashes (n = 17), motor vehicle/pedestrian accidents (n = 12), or severe crush injuries (n = 4). Twenty-one (64%) were admitted in shock. Twenty-one major abdominal venous injuries were present in 17 patients and were lethal in 11 (65%). Abdominal venous injuries were not recognized before laparotomy. Nine of the 33 (27%) patients had extremity vascular injuries associated with orthopedic trauma, and three (9%) had major injuries of thoracic vessels. Only three patients had major abdominal arterial injuries in this series. CONCLUSIONS Vascular injuries resulting from blunt trauma are rare in the pediatric age group. Whereas blunt arterial injuries associated with long bone fractures are readily recognized, easily treated, and result in minimal late morbidity, blunt abdominal venous injuries are rarely recognized before exploration and are lethal in more than half. Devastating venous injuries are more common than arterial injuries after blunt abdominal trauma in children.

Abstract
BACKGROUND We wished to determine the nature and incidence of changes in the iliofemoral arteries after balloon dilation angioplasty (BDA) for aortic arch obstruction in children and to determine the reliability of gradient magnetic resonance imaging (MRI) in their detection. METHODS AND RESULTS Sixty-three children, including 62 with and 1 without arch obstruction, underwent MRI of the iliofemoral vessels. Of these, 36 patients had undergone transfemoral BDA (7 after previous transfemoral diagnostic catheterization), 12 had undergone diagnostic transfemoral catheterization but not BDA, and 15 had no history of femoral arterial catheterization. The iliofemoral arteries were normal on MRI in all 15 children without catheterization. Among the 36 children who had undergone BDA, the ipsilateral iliofemoral artery was normal in 15, mildly narrowing in 7, and severely stenotic or occluded in 14 (39%), including 6 of 9 patients treated for acute femoral artery thrombosis and 8 with no history of femoral artery thrombosis. Two patients had documentation of progressive obstruction. Six patients had concordant conventional angiography. There was a significant correlation between the number of balloon catheters used for the angioplasty and severe occlusive changes. Nine of 19 patients who had undergone diagnostic transfemoral catheterization had severe obstructive changes on MRI; 8 of 9 weighed < 10 kg at catheterization. CONCLUSIONS Obstructive lesions of the iliofemoral arteries are common after transfemoral BDA of arch obstructions (58%) and can be reliably evaluated with gradient MRI. Catheter size and manipulation are the main contributing factors.
