RESUMO
OBJECTIVE: The present study used data from the Japanese Committee for Stentgraft Management's national registry, which contains unique surgical data, including surgical timing, anatomic factors, and pathologic factors, to determine the generalized community experience with thoracic endovascular abdominal aortic repair (TEVAR). METHODS: The medical background and short-term outcomes were reviewed for patients who had undergone TEVAR for a thoracic aortic aneurysm (TAA; 14,235 cases) or aortic dissection (AD; 990 type A and 4259 type B) from 2008 to 2015. TEVAR for AD was separated from that for TAAs; only the background and short-term outcomes were evaluated. The technical outcomes of TEVAR for TAA were also evaluated. All the cases were categorized as follows: elective, urgent (within 24 hours after admission), or emergent (immediately after admission). The outcomes included in-hospital mortality and persistent stroke and paraplegia diagnosed at discharge. The number of debranching bypasses, proximal landing zone (0, 1, 2, ≥3), and zone length were included in the logistic regression analysis. RESULTS: The mortality, stroke, and paraplegia rates in the TAA and AD groups were 4.4%, 4.6%, and 3.7% and 4.0%, 2.9%, and 2.8%, respectively. After analyzing the TAA cohort, we found that urgent and emergent cases were associated with all adverse outcomes. The rate of paraplegia increased drastically in the patients with stent graft coverage that extended for six or more zones. Massive atheroma was associated with stroke and paraplegia. The cumulative survival rate of the TAA group was stratified by the urgency (ie, elective, urgent, emergent; P < .001). We found that the more proximal (0, 1, and 2) the landing zone, the greater the risk of stroke. Likewise, the longer (six or more zones) the coverage, the greater the risk of paraplegia. CONCLUSIONS: Urgency was strongly associated with mortality, stroke, and paraplegia, and the classification of urgent and emergent, according to the surgical timing after admission, successfully stratified the population in the long-term overall survival analysis. A proximal landing zone involving the aortic arch and debranching bypasses were associated with the occurrence of stroke, and the length of stent graft coverage for six or more zones was associated with paraplegia. Identifying these risk factors will help operators of TEVAR develop appropriate operative strategies to mitigate patient risk.

Delayed paraplegia (DP) following thoracoabdominal or descending thoracic aortic (TAA/DTA) repair is a dreaded complication. We reviewed our experience with the management of DP using our previously described COPS protocol (blood-pressure stabilization, cerebrospinal-fluid (CSP) draining and O2-delivery). Complete documentation of hourly CSP pressures and detailed hemodynamic variables were available since 2000. A case-control design was used to analyze the extensive hourly data in the perioperative period. Data were analyzed by contingency-tables, t test, and regression analysis, as appropriate. Between 2000 and 2011, we performed 1059 TAA/DTA repairs. Of these, 47 (4.4%) had DP and 31 (2.9%) had immediate neurologic deficit. Postoperatively, renal replacement therapy and drain complications were significantly associated with DP. Variation in systolic blood pressure (SBP) was also highly predictive. Similarly, spinal-cord perfusion pressure (SCPP = SBP ? SP) showed increased risk with greater variability closer to event day (OR 1.3, P = 0.009). Fluctuation of more than 15 mmHg in SBP in a 24-hour period was associated with 3.2-fold increased odds of DP (P = 0.004). In all, 8/47 (17%) made a full recovery, whereas 19 (40%) had partial recovery by discharge. The 30-day mortality was 18/47 (38%) in DP and 7/55 (13%) in controls (P < 0.001). Long-term survival was significantly lower among DP cases (5-year survival of 28% vs. 75%, P < 0.001). DP occurs infrequently and is predictably associated with intraoperative loss of MEP, postoperative renal replacement therapy, drain complications and unstable systolic and spinal-cord perfusion pressures. Increased vigilance is recommended for patients who experience any of these events.

We describe the case of a young patient with calcifying encephalopathy, born to asymptomatic parents. An extensive hypothesis-driven etiological assessment was performed and failed to detect the precise etiology during many years. We therefore decided to perform whole exome sequencing of the child-unaffected parents trio. A de novo pathogenic variant in the IFIH1 gene which has recently been shown to cause autosomal dominant forms of Aicardi-Goutières syndrome was identified. This child presented with a severe form with neonatal thrombocytopenia and hepatomegaly, the latter having been detected during late gestation. Although first milestones were uneventful, he progressively lost motor skills from the age of 12 months and developed severe spastic paraplegia. Brain imaging revealed white matter abnormalities and extensive calcifications. He also presented atypical skin lesions, different from chilblains. His medical history was marked by two episodes of acute pancreatitis. We provide herein the results of pathological examination including detailed description of the neuropathological hallmarks. To our knowledge, this the first detailed clinico-pathological description of a patient with an IFIH1 pathogenic variant.

Type A acute aortic dissection is a life-threatening vascular emergency because of its high morbidity and mortality. Platelet is a pivotal ingredient involved in the development of acute aortic dissection. In this study, we aimed to investigate whether mean platelet volume (MPV)/platelet count ratio predicts in-hospital complications and long-term mortality in type A acute aortic dissection. In this single-center and prospective cohort study, 106 consecutive patients with Stanford type A acute aortic dissection admitted to the hospital within 12âh after onset were recruited. The best cut-off value of MPV/platelet count ratio predicting all-cause mortality was determined by the receiver operator characteristic analysis. Patients were divided into high (H-MPV/platelet count) and low (L-MPV/platelet count) groups based on the cut-off value of 7.49 (10âfl/10/l). Patients were followed up for 3.5 years. Of the 106 acute aortic dissection patients, 71 (67.0%) died during the study period, with a median follow-up duration of 570 days. Compared to the L-MPV/platelet count group, patients with H-MPV/platelet count had a higher risk of in-hospital complications including hypotension, hypoxemia, myocardial ischemia/infarction, conscious disturbance, pericardial tamponade, paraplegia, and poor survival (all Pâ<â0.05). In multivariable Cox regression models adjusted for potential confounders, MPV/platelet count ratio was positively associated with the hazard of all-cause mortality, irrespective of interventions either with medication only or urgent surgery, and the hazard ratios were 2.81 (95% confidence interval 1.28-4.48) for the H-MPV/platelet count group when taking L-MPV/platelet count group as the reference (Pâ=â0.005). The MPV/platelet count ratio was a strong independent predictor for in-hospital complications and long-term mortality in patients with type A acute aortic dissection.

The reported long-term outcome of endemic Burkitt lymphoma (eBL) patients who present with paraplegia is largely unknown. Records of BL patients treated with comparable short-interval cyclophosphamide chemotherapy schedules between 2004 and 2014 at three Baptist mission hospitals in Cameroon were reviewed. Survivors were followed up and examined at home or in hospital. Eighty-seven of 948 (9.2%) patients had paraplegia at diagnosis. The survival rate in eBL patients with paraplegia at diagnosis was 33% (n = 29) after follow-up of between 2 and 96 (median 40) months. Seven patients (24%) had neurological sequelae and needed rehabilitation. There was no relationship between the duration of symptoms (<2, 2-4, >4 weeks) and the survival rate or the risk to have neurological sequelae. The survival rate and risk for sequelae were similar in patients with confirmed St. Jude stage III and IV diseases.

INTRODUCTION: Spinal cord ischemia is a potentially devastating complication of thoracic aortic surgery. However, predictors of outcome have not been well characterized. The study objective was to generate a prognostic score that accurately stratifies patient outcomes, aiding in future management and planning. METHODS: A retrospective review of 224 consecutive open thoracic aortic surgeries identified patients with spinal cord ischemia, defined as changes on intraoperative somatosensory evoked potentials (SSEP) and/or paraparesis/paraplegia postoperatively. The outcome of interest was poor outcome, defined as death or discharge with a lower extremity motor score ≤40, indicating impaired ambulation. Demographic and clinical characteristics were tested in univariate analyses and significant factors were incorporated in multivariate modeling to determine independent predictors of poor outcome. RESULTS: Seventy-five patients were identified with spinal cord ischemia, of which 43(57 %) had poor outcomes including 28(37 %) that died prior to discharge. Factors associated with poor outcome in univariate analysis included absent lumbar CSF drain (p = 0.03), surgical repair that crossed the diaphragm (p = 0.002), permanent intraoperative SSEP change (p = 0.02), postoperative renal failure (p = 0.004), paraplegia (p = 0.001), and concomitant stroke (p = 0.04). In multivariable analysis, surgical repair crossing the diaphragm (OR 4.8, CI 1.4-16.7, p = 0.02), paraplegia (OR 4.5, CI 1.4-14.0, p = 0.01), and renal failure (OR 6.1, CI 1.7-21.2, p = 0.005) were independently associated with poor outcome. Patients with transient intraoperative neurophysiologic changes were least likely to have poor outcome when compared to patients with no or permanent SSEP changes, and those not monitored (p = 0.03). CONCLUSION: Development of spinal cord ischemia with thoracic aortic repair often leads to death or disability. Characteristics known at the time of event can accurately predict the likelihood of poor outcome.

OBJECTIVE: To evaluate the vital prognosis of patients with metastatic epidural spinal cord compression (MESCC) to determine the relevance and duration of physical medicine and rehabilitation (PM&R) admission. DATA SOURCES: Publications from 1980 to January 2010 selected from 3 databases. STUDY SELECTION: Publications reporting data correlated with survival and prognosis factors, highlighting publications with level A scientific evidence (prospective randomized controlled studies with significant casuistry and relevant judgment criteria). The work focused on patients with MESCC below T1. DATA EXTRACTION: Standardized reading grid. DATA SYNTHESIS: Thirty-eight studies met the inclusion criteria. Most were retrospective. For survival rate at 1 year, they reported data ranging from 12% to 58%. The 12-month and median survival rates were the data reported most often in the articles. The median survival rate ranged from 2.4 to 30 months, and 12-month survival rates ranged from 12% to 58%. Of publications that chose this parameter, 95% reported 12-month survival rates less than 55.2% (95th percentile) regardless of patients' functional status and associated risk factors (eg, location of primary cancer, metastases spreading, pretreatment ambulatory status). CONCLUSIONS: Despite major progress in cancer care, patients with MESCC still have a limited vital prognosis. The relevance and duration of PM&R care must be evaluated against the patient's functional need for rehabilitation while making time for family. The hypothesis of a 1-month stay extended only once appears reasonable for patients to adapt to their new functional status without taking precious time away from their loved ones.

OBJECTIVE: To identify functional outcomes that could justify the need for a rehabilitation care program for patients with metastatic epidural spinal cord compression (MESCC) and paraplegia. DATA SOURCES: Publications from 1950 to January 2010 selected from 3 databases. STUDY SELECTION: Original articles dealing with outcome data for functional status, pain, and bladder dysfunction. DATA EXTRACTION: Standardized reading grid. DATA SYNTHESIS: The data are dominated by retrospective studies for even functional-related data, and studies from rehabilitation teams are rare. They report a functional evolution similar to a population with traumatic spinal cord injury for the first 3 months. Patients who were ambulatory before treatment retained their ability to walk, and patients who were nonambulatory before treatment could regain gait abilities. Data also showed a positive impact on pain and bladder and/or bowel dysfunction. CONCLUSIONS: By restricting physical medicine and rehabilitation therapeutic care to a short time (1-2mo), the progression margin is possible in the short term and implies a voluntary and active therapeutic care approach for patients with paraplegia after MESCC on the basis of a codified and standardized program with clinical indicators, as well as patients' comfort indicators.

STUDY DESIGN: Retrospective study. OBJECTIVES: To determine the potential impact of rehabilitation care on associated symptoms and functional improvements of paraplegic patients with metastatic spinal cord compression. SETTING: CMN Propara, Montpellier (France). MEASURES: Demographics, Functional Independence Measure (FIM), Frankel Modified Score and Visual Analog Scale (VAS) for pain, intercurrent adverse medical events and neurological outcome, duration of stay, survival time, rehospitalization in a non-Spinal Cord Injury unit, number of contracts defining the patients rehabilitation goals, number of contracts defining the patients duration of stay within the rehabilitation center. RESULTS: We reviewed the charts of 26 patients. The initial neurological profile was paraplegia or paraparesis for 24 patients and quadriparesis for 2 patients. Regarding functional improvements: four patients demonstrated a poor functional evolution, five patients showed no functional improvements or very slight improvements and all the other patients showed an increase in their overall functional aptitudes. At the end of the stay, 14 patients were urinary independent. Our study reports 52 rehospitalizations in an another unit and 101 outpatient visits during their rehabilitation stay in a physical medicine and rehabilitation (PM&R) center. For the 14 patients who were deceased at the time of data collection, the median survival rate post-paraplegia was 12.7 months. A total of 12 of the 14 patients spent more than a third of their remaining survival time in a rehabilitation center. DISCUSSION: Compared to the patients' life expectancy, their stay in a rehabilitation center is too long and prevents them from spending time with family and loved ones. The occurrence rate of the associated symptoms is high because of both cancer-related disorders and neurological disorders caused by the spinal cord lesion. PM&R professionals are faced with patients affected by chronic pain and fatigue as well as frequent rehospitalizations, short stays and outpatient stays, in the primary oncology unit. This study focuses on the need to privilege the patients' comfort over their functional rehabilitation.

STUDY DESIGN: Retrospective clinical study. OBJECTIVE: The aim of this study was to examine whether the Tokuhashi score correlates with the neurologic outcome in early surgical treatment in metastatic spinal cord compression (MSCC). A retrospective analysis of 35 consecutive incomplete tetraplegic and paraplegic patients with vertebral metastases (VM) and spinal cord compression (SCC) was performed. SUMMARY OF BACKGROUND DATA: MSCC is a challenging problem in VM and constitutes an oncologic emergency. The Tokuhashi score has been modified recently and seems to constitute the best method of prediction for real survival in patients with VM. Until now the influence of the neurologic status as a prognostic factor has been discussed controversially. METHODS: Data of 35 patients with VM and incomplete tetraplegia or paraplegia, who underwent surgical treatment, were reviewed retrospectively from 2005 to 2006 at our hospital. All patients were classified among the American Spinal Injury Association (ASIA) Impairment Scale (AIS) before and after surgery and at the follow-up. Data were analyzed with SPSS 15.0 and correlation coefficients (Spearman rho) were computed. RESULTS: Analysis showed that 19 patients (54.3%) with an average Tokuhashi score of 9 showed an improvement in the AIS, whereas 12 (34.3%) patients with an average score of 8 had no change and 4 (11.4%) patients with a score of 7 had deterioration. AIS changes showed a positive correlation with Tokuhashi score (r = 0.33; P = 0.048). CONCLUSION: Our clinical observation suggests that patients with spinal metastases and a high Tokuhashi score benefit from surgical treatment with moderate improvement in sensomotoric function even in a heterogenic collective.

OBJECTIVE: Paraplegia after thoracoabdominal aneurysm (TAA) repair has been associated with poor survival. Little information exists concerning the spectrum of severity that characterizes spinal cord ischemic (SCI) complications. This study stratified SCI by deficit severity to determine its impact on late survival and functional outcomes. METHODS: A review of our prospectively maintained thoracic aortic database was performed from May 1987 through December 2005 to identify patients who experienced SCI of any extent after TAA repair. During this period, 576 patients underwent descending thoracic aortic repair (93 open, 105 endovascular [TEVAR]) or open TAA repair (279 extent I to III; 99 extent IV). To stratify severity of SCI, we created a spinal cord ischemia deficit (SCID) scale, which is defined as: I, flaccid paralysis; II, average neurologic muscle grade indicating <50% function; and III, average neurologic muscle grade indicating >50% function. Long-term outcomes were evaluated in relation to these groups by actuarial methods. RESULTS: During the study period, 64 (11.1%) patients developed SCI of any severity (7 of 105 [6.6%] TEVAR, 57 of 471 [12%] open). These were stratified by SCID level: I, 24 (37.5%); II, 31 (48.4%); and III, 9 (14.1%). SCI was immediate in 33 (54.1%) and delayed in 28 (45.9%). Most SCI (6 of 7) associated with TEVAR was delayed. The 30-day mortality was significantly higher in the SCI group than the overall patient cohort (15 of 64 [23.4%] vs 41 of 512 [8%], P < .001) and varied by SCID level: I, 11 of 24 (45.8%); II, 4 of 31 (12.9%); and III, 0 of 9 (0%; P = .001). The 5-year actuarial survival for all SCI was lower than for non-SCI patients (25% +/- 6% vs 51% +/- 3%, P < .001) and varied linearly with SCID level but was similar between SCID II/III and the non-SCI patients (41% +/- 10% vs 51% +/- 3%, P = .281). No SCID I patients were alive at 5 years. No patients with SCID I recovered the ability to walk, but eight of 11 (73%) with SCID II and the nine (100%) with SCID III could ambulate with or without assistance at last follow-up. CONCLUSION: Survival and functional outcomes correlate with SCI severity. Patients with SCID I have a poor long-term outlook. Survival of SCID II/III patients is similar to non-SCI patients; most recover the ability to ambulate.

OBJECTIVE: Stent grafting has become the first-line approach to traumatic thoracic aortic transections (TTAT) in some trauma centers due to a perceived decrease in morbidity and mortality compared with standard open repair. We reviewed contemporary outcomes of patients undergoing endovascular repair of TTAT (endoTTAT) and those undergoing open repair (openTTAT) to determine if current reported results support first-line use of endoTTAT. METHOD: Retrospective, nonrandomized studies published in English (>5 cases/report) involving TTAT listed in PubMed between 2001 and 2006 were systematically reviewed. Periprocedural outcomes between endoTTAT and openTTAT were analyzed. Mean follow-up was 22.9 months for endoTTAT (reported for 22 of 28 studies) and 48.6 months for openTTAT (reported for 5 of 12 studies). For statistical analysis, t tests were used. RESULTS: We analyzed 33 articles reporting 699 procedures in which 370 patients treated with endoTTAT and 329 patients managed with openTTAT. No statistical differences were found between patient groups in mean age (41.3 vs 38.8 years, P < .10), injury severity score (39.8 vs 36.0, P < .10), or technical success rates of the procedure (96.5% vs 98.5%, P = .58). In contrast, mortality was significantly lower in the endoTTAT group (7.6% vs 15.2%, P = .0076) as were rates of paraplegia (0% vs 5.6%, P < .0001) and stroke (0.85% vs 5.3%, P = .0028). The most common procedure-related complications for each technique were iliac artery injury during endoTTAT and recurrent laryngeal nerve injury after openTTAT. CONCLUSIONS: To our knowledge, no large multicenter prospective randomized trial comparing endoTTAT and openTTAT has been published in the literature. This meta-analysis of pooled data serves as a surrogate, demonstrating a significant reduction in mortality, paraplegia, and stroke rates in patients who undergo endoTTAT; however, the long-term durability of endoTTAT remains in question.

Open surgery for thoracic aortic disease is associated with significant morbidity and the reported rates for paraplegia and stroke are 3%-19% and 6%-11%, respectively. Spinal cord ischemia and stroke have also been reported following endoluminal repair. This study reviews the incidence of paraplegia and stroke in a series of 186 patients treated with thoracic stent grafts. From July 1997 to September 2006, 186 patients (125 men) underwent endoluminal repair of thoracic aortic pathology. Mean age was 71 years (range, 17-90 years). One hundred twenty-eight patients were treated electively and 58 patients had urgent procedures. Anesthesia was epidural in 131, general in 50, and local in 5 patients. Seven patients developed paraplegia (3.8%; two urgent and five elective). All occurred in-hospital apart from one associated with severe hypotension after a myocardial infarction at 3 weeks. Four of these recovered with cerebrospinal fluid (CSF) drainage. One patient with paraplegia died and two had permanent neurological deficit. The rate of permanent paraplegia and death was 1.6%. There were seven strokes (3.8%; four urgent and three elective). Three patients made a complete recovery, one had permanent expressive dysphasia, and three died. The rate of permanent stroke and death was 2.1%. Endoluminal treatment of thoracic aortic disease is an attractive alternative to open surgery; however, there is still a risk of paraplegia and stroke. Permanent neurological deficits and death occurred in 3.7% of the patients in this series. We conclude that prompt recognition of paraplegia and immediate insertion of a CSF drain can be an effective way of recovering spinal cord function and improving the prognosis.

PURPOSE: To examine the efficacy of a staged approach for the treatment of thoracoabdominal aneurysms, with open visceral revascularization followed by aortic endografting, in selected patients not considered candidates for conventional surgical repair. METHODS: A retrospective review was conducted of 13 consecutive patients (8 women; mean age 64 years, range 33-77) who underwent visceral bypass followed by endovascular thoracoabdominal stent-graft implantation since 1999. Three patients presented with symptomatic aneurysms and 2 with rupture. Two patients had connective tissue disorders. All patients were deemed unfit for conventional thoracoabdominal repair due to comorbid conditions. The procedures were tailored to the pathology and specific patient anatomical situation: 5 aortic dissections with aneurysmal degeneration and 8 aneurysms (5 Crawford type II, 2 type III, and 1 type IV). RESULTS: The patients underwent retrograde visceral bypass (11 iliovisceral and 2 infrarenal aortic to visceral artery) followed by endovascular aortic relining with Zenith TX2 devices (n=7), homemade endografts (n=5), or a Talent thoracic endograft (n=1). Six patients required either a proximal or distal direct aortic repair (2 infrarenal reconstructions, 3 arch elephant trunk grafts, and 1 ascending aortic repair), while 3 patients also underwent left carotid-subclavian bypass grafting. Two patients developed paraplegia (1 following a ruptured aneurysm), and 2 patients had transient paraparetic events. Two patients had acute renal failure requiring short-term dialysis. Three patients died within 30 days; 2 late aneurysm-related deaths were noted. Three patients developed endoleaks during follow-up. Mean lengths of stay were 13 days (7-30) for the visceral bypass and 12 (3-25) for the endovascular stent-graft. In addition, remaining procedures in 8 patients required a mean of 7 days (0-14) in hospital. CONCLUSION: Staged endovascular and open procedures are feasible for thoracoabdominal aneurysms in patients at prohibitive risk for open thoracoabdominal reconstruction. However, this approach still carries a significant risk of perioperative mortality and morbidity. The potential for less invasive alternatives should be investigated.

BACKGROUND: The risk factors of paraplegia and paraparesis (P/P) after surgical repair of descending thoracic aortic aneurysm (TAA) are controversial. PATIENTS AND METHODS: Seventy five patients underwent surgical repair of descending TAA from 2001 through 2002. The mean age was 64.2+/-5.2 years old (range; 26-81) and 58 patients (77.3%) are male. There were 47 patients (62.7%) with nondissecting aortic aneurysm and 28 patients (37.3%) with chronic dissecting aortic aneurysm. Emergent operation was performed in 13 cases (17.3%). Retrospective analysis based on data of these 75 patients was performed to determine the risk factors of P/P. RESULTS: 30-days hospital mortality was 2.7%. The overall incidence of P/P was 12.0% (9/75) overall (immediate paraplegia; 4 (5.3%), delayed paraplegia; 1 (1.3%), immediate paraparesis; 3 (4.0%), delayed paraparesis; 1 (1.3%)). Logistic regression analysis revealed that predictive factors of the development of P/P were; cases in which the distal part (below Th9) of the descending thoracic aorta was included in the extent of graft replacement (P=0.020; odds ratio (OR), 7.981) and nondissecting aneurysm (P=0.029; OR, 12.109). CONCLUSION: There was an increased risk of P/P after descending TAA repair in cases in which the extent of graft replacement included below the Th9 or in cases with nondissecting aortic aneurysm.

We present survival, neurological function, and complications in a consecutive series of 282 patients operated for spinal metastases from January 1990 to December 2001. Our main surgical indication throughout this time period was neurological deficit rather than pain. Metastases from cancer of the prostate accounted for 40%, breast 15%, kidney 8%, and lung 7%. In 78% the level of decompression was thoracic and lumbar in 22%. Thirteen percent had a single metastases only, 64% had multiple skeletal metastases, and 23% had non-skeletal metastases also. Preoperatively 64% were non-walkers (Frankel A-C), 30% could walk with aids (Frankel D) and 8% had normal motor function (Frankel E). Posterior decompression and stabilization was applied in 212 patients, 47 had laminectomy only, and 23 had anterior decompressions and reconstruction. Complications were recorded at a level of 20%, and systemic complications were often associated with early death. The survival rate was 0.63 at 3 months, 0.47 at 6 months, 0.30 at 1 year, and 0.16 at 2 years. Twelve of 255 (5%) patients with motor deficits were worsened postoperatively, whereas 179 (70%) improved at least one Frankel grade. The ability to walk postoperatively was retained during follow-up in more than 80% of the patients. This study shows that important improvement of function can be gained by surgical treatment, but the complication rate was high and many patients died of their disease within the first months of surgery.

A review of the presentation, management and outcome in all children presenting with non-traumatic paraplegia managed by the paediatric neurology team at the University College Hospital Ibadan, Nigeria from June 1989 to May 2004 is presented. Of the 110 patients, there were 54 males and 56 females giving a M:F ratio of 1:1. The mean age of the group was 5.3 (SD = 3.1) years, with a range from 9 months to 11 years. Infections and infectious processes caused the paraplegia in 102 (92.7%) of the cases with poliomyelitis and tuberculosis (TB) of the spine accounting for 88 (80%) of cases. The study period was divided into three 5 year periods. While poliomyelitis was the commonest cause of paraplegia (60%) in the first 5 years: TB spine was responsible for most cases (40%) in the last 5-year period of the study. There was a significant reduction in the total number of cases seen when the initial 5-year period was compared with the last (45 and 26 respectively, P = 0.001). Overall mortality among the 110 admitted patients was 7.2% being highest (50%) in malignant disorders and none was recorded in TB spine. Prognosis for eventual ability to walk was best in cases of TB spine where 37 of the 39 patients (95%) were ambulant by discharge after 60 days of anti-TB treatment. The 2 non-ambulant patients eventually walked within 3 months of discharge while on maintenance treatment for TB. Only 2 of the 51 non-ambulant patients obtained wheelchairs at discharge. The implications of inadequate facilities for investigation and treatment as well as the lack of financial and social support for the families of affected children are discussed.

HYPOTHESIS: Systemic temperature influences the development of neurologic deficits after aortic surgery. DESIGN: Retrospective case-comparison study of prospectively collected data. SETTING: Tertiary referral center. PATIENTS AND INTERVENTIONS: We examined spinal cord injury according to mild passive hypothermia (mean temperature, 36.5 degrees C; n = 25), moderate active hypothermia (temperature range, 29 degrees C-32 degrees C; n = 76), or profound hypothermia (temperature, <20 degrees C; n = 31) for complex repairs in 132 patients. Aortic dissection was present in 67 patients (51%), 41 (31%) had leaks or rupture, 39 (30%) were reoperations on the descending thoracic aorta, and 27 (20%) had concurrent arch and/or ascending thoracic aortic repairs. MAIN OUTCOME MEASURE: Occurrence of permanent and transient deficits. RESULTS: Five patients (3.8%) had permanent deficits. One (4.0%) of the 25 patients underwent mild hypothermia, 3 (3.9%) of the 76 patients who underwent moderate hypothermia, and 1 (3.2%) of the 31 patients who underwent profound hypothermia (P =.70). Reversible deficits occurred in 7 patients (total 32%) who underwent mild hypothermia, 2 patients (total 6.6%) underwent moderate hypothermia, and 1 (total 6.5%) underwent profound hypothermia (P =.004). Six were delayed neurologic deficits. Independent predictors were intercostal ischemic time (P =.02), mild hypothermia (P =.004), and no cerebrospinal fluid drainage (P =.05). The total 30-day survival was 92.4% (122 of 132 patients). The only multivariable predictor of death was acuity of surgery (namely, emergent, urgent, or elective) (P =.06). CONCLUSIONS: Moderate or profound hypothermia resulted in fewer transient neurologic deficits. Thus, we recommend active cooling and cerebrospinal fluid drainage for most patients, and profound hypothermia for patients undergoing complex repairs and reoperations.

BACKGROUND: The prevention of immediate and delayed paraplegia after thoracoabdominal aorta surgery relies on hemodynamic maneuvers (aimed at restoration of an adequate spinal cord perfusion pressure) and cytoprotective measures (hypothermia, drugs). METHODS: The indications for implementing these measures can be provided by motor-evoked potential (MEP) or somatosensory-evoked potential (SEP) monitoring. RESULTS: Intraoperative interactions between the surgeon and the neurophysiologist can be described by algorithms to be applied in the presence or absence of intraoperative MEP or SEP changes. CONCLUSIONS: It should be noted that normal SEPs or MEPs at the end of surgery do not systematically guarantee the nonoccurrence of delayed paraplegia, especially when segmental arteries have been ligated, in which case postoperative SEP monitoring is indicated.

BACKGROUND: Hypothermic cardiopulmonary bypass with circulatory arrest is an important adjunct for operations on the distal aortic arch, the descending thoracic, and the thoracoabdominal aorta. The safety and efficacy of this technique when compared with other adjuncts (ie, simple aortic clamping, partial cardiopulmonary bypass, regional hypothermia) is not clearly established. METHODS: One hundred and ninety-two patients (age range, 20 to 83 years) with descending thoracic or thoracoabdominal aortic disease had resection and graft replacement of the involved aortic segments using hypothermic cardiopulmonary bypass and intervals of circulatory arrest (mean, 38 minutes). The technique was used when the location and severity of disease precluded placement of clamps on the proximal aorta (31 patients) or (in 161 patients) when extensive thoracic (47) or thoracoabdominal (114) aortic disease was present, and the risk for development of spinal cord ischemic injury was judged to be increased. Lower intercostal and lumbar arteries were attached separately to the aortic graft in 101 of the 161 patients (63%) who had extensive aortic replacement. No other adjuncts for spinal cord protection were used. RESULTS: The 30-day mortality was 6.8% (13 patients). It was 40% (8 of 20) for patients having emergent operations (acute aortic dissection or rupture) and 2.9% (5 of 172) for all others (p < 0.001). The 90-day mortality was 12.5% (24 patients). Paraplegia occurred in 4 and paraparesis in 1 (full recovery) of the 186 operative survivors whose lower limb function could be assessed postoperatively (2.7%). Among the 109 survivors with thoracoabdominal aortic disease, early paraplegia occurred in 1 of 36 with Crawford extent I, 0 of 42 with extent II, and 2 of 31 with extent III disease. One patient (extent II) developed paraplegia on the 9th postoperative day after a hypotensive episode. None of the 47 patients with aortic dissection developed paralysis. Among the 186 operative survivors, renal dialysis was required in 4 patients (2.2%), prolonged inotropic support in 18 (10%), reoperation for bleeding in 9 (5%), mechanical ventilation (> or = 48 hours) in 64 (34%), and tracheostomy in 17 (9%). Four patients (2%) sustained a stroke. CONCLUSIONS: Hypothermic cardiopulmonary bypass with circulatory arrest provides safe and substantial protection against paralysis and renal, cardiac, and visceral organ system failure that equals or exceeds that of other currently used techniques but without the need of other adjuncts.
