Background and Purpose: Paravertebral arteriovenous shunts (PVAVSs) are rare. Whether the intradural venous system is involved in drainage may lead to differences in clinical characteristics through specific pathophysiological mechanisms. This study aims to comprehensively evaluate the natural history and clinical outcomes of PVAVSs with or without intradural drainage. Methods: Sixty-four consecutive patients with PVAVSs from 2 institutes were retrospectively reviewed. Lesions were classified as type A (n=28) if the intradural veins were involved in drainage; otherwise, they were classified as type B (n=36). The clinical course from initial presentation to the last follow-up was analyzed. Results: The patients with type A shunts were older at presentation (52.5 versus 35.5 years, P <0.0001) and more likely to have lower spinal segments affected than patients with type B PVAVSs (67.8% versus 13.9%, P =0.00006). After presentation, the deterioration rates related to gait and sphincter dysfunction were significantly higher in patients with type A than type B shunts (gait dysfunction: 71.8%/y versus 17.0%/y, P =0.0006; sphincter dysfunction: 63.7%/y versus 11.3%/y, P =0.0002). According to the angiogram at the end of the latest treatment, 79% of type A and 75% of type B PVAVSs were completely obliterated. If the lesions were partially obliterated, a significantly higher clinical deterioration rate was observed in patients with type A shunts than those with type B shunts (69.9%/y versus 3.2%/y, P =0.0253). Conclusions: Type A PVAVSs feature rapid progressive neurological deficits; therefore, early clinical intervention is necessary. For complex lesions that cannot be completely obliterated, surgical disconnection of all refluxed radicular veins is suggested.

AbstractRadiation-induced cavernous malformations (RICMs) are delayed complications of brain irradiation during childhood. Its natural history is largely unknown and its incidence may be underestimated as RCIMS tend to develop several years following radiation. No clear consensus exists regarding the long-term follow-up or treatment. A systematic review of Embase, Cochrane Library, PubMed, Google Scholar, and Web of Science databases, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, was performed. Based on our inclusion/exclusion criteria, 12 articles were included, totaling 113 children with RICMs, 86 were treated conservatively, and 27 with microsurgery. We were unable to precisely define the incidence and natural history from this data. The mean age at radiation treatment was 7.3 years, with a slight male predominance (54%) and an average dose of 50.0 Gy. The mean time to detection of RICM was 9.2 years after radiation. RICM often developed at distance from the primary lesion, more specifically frontal (35%) and temporal lobe (34%). On average, 2.6 RICMs were discovered per child. Sixty-seven percent were asymptomatic. Twenty-one percent presented signs of hemorrhage. Clinical outcome was favorable in all children except in 2. Follow-up data were lacking in most of the studies. RICM is most often asymptomatic but probably an underestimated complication of cerebral irradiation in the pediatric population. Based on the radiological development of RICMs, many authors suggest a follow-up of at least 15 years. Studies suggest observation for asymptomatic lesions, while surgery is reserved for symptomatic growth, hemorrhage, or focal neurological deficits.

Object The purpose of this study was to examine the prevalence of intracranial cavernous malformations (CMs) in a large series of predominantly Caucasian patients with spinal cord CMs. The authors also studied the natural history of spinal CMs in patients who were treated nonoperatively. Methods The medical records of 67 consecutive patients (32 female and 35 male patients) in whom a spinal CM was diagnosed between 1994 and 2002 were reviewed. The patients’ mean age at presentation was 50 years (range 13–82 years). Twenty-five patients underwent resection of the lesion. Forty-two patients in whom the spinal CM was diagnosed using magnetic resonance (MR) imaging were followed expectantly. Thirty-three (49%) of 67 patients underwent both spinal and intracranial MR imaging. All available imaging studies were reviewed to determine the coexistence of an intracranial CM. Fourteen (42%) of the 33 patients with spinal CMs who underwent intracranial MR imaging harbored at least one cerebral CM in addition to the spinal lesion. Six (43%) of these 14 patients did not have a known family history of CM. Data obtained during the long-term follow-up period (mean 9.7 years, total of 319 patient-years) were available for 33 of the 42 patients with a spinal CM who did not undergo surgery. Five symptomatic lesional hemorrhages (neurological events), four of which were documented on neuroimaging studies, occurred during the follow-up period, for an overall event rate of 1.6% per patient per year. No patient experienced clinically significant neurological deficits due to recurrent hemorrhage. Conclusions As many as 40% of patients with a spinal CM may harbor a similar intracranial lesion, and approximately 40% of patients with coexisting spinal and intracranial CMs may have the nonfamilial (sporadic) form of the disease. Patients with symptomatic spinal CMs who are treated nonoperatively may have a small risk of clinically significant recurrent hemorrhage. The findings will aid in evaluation of surveillance images and in counseling of patients with spinal CMs, irrespective of family history.

Abstract OBJECTIVES The aim of this study was to investigate the clinical outcomes and follow-up results among 5 main aortic arch surgery methods for type A aortic dissection in a single centre. METHODS From 2002 to 2018, 958 type A aortic dissection patients who received surgical repair were divided into 5 groups according to the arch surgery method: hemiarch replacement (n = 206), island arch replacement (n = 54), total arch replacement with frozen elephant trunk (n = 425), triple-branched stent (n = 39) and fenestrated stent (n = 234). The indications for the different arch methods were related to the patient’s preoperative status, the location and extent of the dissection and the surgical ability of the surgeons. A comparative study was performed to identify the differences in the perioperative data, and the Kaplan–Meier analysis was used to assess the long-term survival and reintervention rates. Thirty matched surviving patients that were included in each group completed Computed tomography angiography to determine long-term reshaping effect. RESULTS The 30-day mortality rate was 15.8%, and there was no difference among the 5 groups (P = 0.848). The follow-up survival rates were similar among the 5 groups (P = 0.130), and the same was true for patients without reintervention (P = 0.471). In the propensity matching study, patients with stents (frozen elephant trunk, triple-branched stent, fenestrated stent) had a slower aortic dilation rate and a higher ratio of thrombosis in the false lumen at the descending aortic and abdominal aortic levels than patients without stents. CONCLUSIONS No standard method is available for arch surgery, and indications and long-term effects should be identified with clinical data. In our experiences, simpler surgical procedures could reduce mortality in critically ill patients and stents in the distal aorta could improve long-term reshape effects.

Surgical treatment of periprosthetic femoral fractures has a high complication and mortality rate of more than 10%. The aim of this study is to report the outcome of a consecutive single center patient group. Thirty-four consecutive patients (mean age 81.2+/-8.5 years, 14 male, 20 female) with a periprosthetic femoral fracture Vancouver type A (n=5) or type B (n=29) were followed-up after 43.2 months, none of the patients were lost to follow- up. Nineteen of the patients were treated through change of the stem and cerclage fixation, five by plates and ten by cerclage cables. One successfully treated infection was observed. No further complications have been reported peri- or postoperatively, therefore resulting in 2.9% overall complication rate. These results demonstrate that precisely selected revision surgery protocol following periprosthetic femoral fractures within elderly multimorbid patients may lead to beneficial outcomes at a low risk of complications.

Abstract Background:In rare instances, aggressive vertebral hemangiomas (VHs) can cause compression fracture, resulting in severe pain and neurological deficits. But the diagnosis and treatment of these aggressive lesions are challenging because of these lesions are rare and atypical. This study aimed to evaluate the safety and efficacy of surgical management for aggressive VHs with vertebral compression fracture by a modified multimodality surgery.Methods:We retrospectively reviewed 6 cases suffering from aggressive VHs with compression fracture and neurological deficits in our department from July 2011 to April 2016. These patients were treated by the multimodality surgery, includingpreoperative embolization, intraoperative injection of gelfoam mixed with cement, and laminectomy decompression.The follow-up period was at least 3 years. Perioperative parameters, clinical outcomes, and radiographical data were collected and analyzed.Results: The 6 patients involved 1 male and 5 females (mean age, 52.3 years).The levels involved were: in thoracic spine (5 cases) and lumbar spine (1 case).Preoperative CT-guided biopsy was conducted in all patients, with 5 patients had definitive pathologic diagnosis. All patients were treated successfully with the multimodal surgery, with no cement leakage and other severe complications. The mean operation time was 182.2 minutes, and the estimated blood loss was 908.3 ml.At an average follow-up of 49.8 months, clinical outcomes assessed by the visual analogue scale and Frankel grade were significantly improved. The vertebral body height and kyphosis angle of the fractured vertebra were also corrected postoperatively. No affected vertebra re-fracture and adjacent vertebral fracture were developed, and none of the patients experienced recurrence of tumor at final follow-up.Conclusions:In cases of aggressive VHs causing compression fracture with neurological deficits, CT-guided biopsy is indicated for the diagnosis. The multimodality surgery (preoperative embolization, intraoperative injection of gelfoam mixed with bone cement combined laminectomy decompression) is effective and safe, and can be considered as an acceptable surgical choice.

Abstract Objective: Load bearing capacity of the bone structure of anterolateral weight-bearing area plays an important role in the progressive collapse in osteonecrosis of the femoral head (ONFH). The purpose of this study is to assess the efficacy of combined evaluation of anteroposterior (AP) and frog-leg lateral (FLL) view to diagnose collapse.Methods: Between December 2016 to August 2018, a total of 478 hips from 372 patients with ONFH (268 men, 104 women; mean age 37.9±11.4 years) were retrospectively evaluated. All patients received standard AP and FLL views of hip joints. Japanese Investigation Committee (JIC) classification system was used to classified necrotic lesion in AP view. Anterior necrotic lesion was evaluated by FLL view. All patients with precollapse ONFH underwent non-operative hip preserving therapy. The collapse rate was calculated and compared with Kaplan–Meier survival analysis with radiological collapse as endpoints.Results: Forty-four (44/478, 9.2%) hips were classified as type A, 65 (65/478, 13.6%) as type B, 232 (232/478, 48.5%) as type C1, and 137 (137/478, 28.7%) as type C2. Three hundred cases (300/478, 62.5%) were collapsed at the initial time point. Two hundred and twenty six (226/300, 75.3%) hips and 298 (298/300, 99.3%) hips collapse were identified with AP view and FLL view, respectively. An average follow-up of 37.0±32.0 months was conducted to evaluate the occurence of collapse in 178 precollapse hips. During follow-up period, collapse occurred in 89 hips (50.0%). Seventy-seven (77/89, 86.5%) hips was determined with AP view alone and 85 (85/89, 95.5%) hips were determined with combination of AP and FLL views. The collapse rate at five years were reported as 0% and 0%, 16.2% and 24.3%, 58.3% and 68.1%, and 100% and 100% according to combination of AP and FLL views or AP view alone for types A, B, C1, and C2, respectively.Conclusion: The collapse can be diagnosed more accurately by combination of AP and FLL views. Besides, JIC type A and type B ONFH can be treated with conservative hip preservation, but precollapse type C2 ONFH should be treated with joint-preserving surgery. Type C1 needs further study to determine which subtype has potential risk of collapse.

Abstract Background Proteinuria is a marker of poor outcomes in several diseases; however, few studies have been conducted to explore the prognostic value of proteinuria, assessed by urine dipstick test, for clinical outcomes in patients with type B acute aortic dissection (TBAD) undergoing thoracic endovascular aortic repair (TEVAR). Methods Consecutive patients with TBAD undergoing TEVAR were enrolled from January 2010 to July 2015. Proteinuria was defined as trace or higher, according to the results of urine dipstick testing. Associations among proteinuria and adverse events were evaluated. Results In total, 671 patients with a mean age of 44±15 years were included in the analysis. Proteinuria was detected in 281 patients (41.9%) before TEVAR. Multivariate logistic regression analysis showed that C-reactive protein and impaired renal function were independent predictors for proteinuria. During hospitalization, 21 patients died. In-hospital mortality was higher in patients with proteinuria (1.5% vs. 5.3%, p=0.005). After a median 3.4 years follow up, the post-TEVAR death rate was 10.4% (85 patients were lost to follow-up). The long-term cumulative mortality was significantly higher in patients with proteinuria (17.2% vs. 8.2%, log-rank=11.36, p=0.001). Multivariate Cox survival modeling indicated that proteinuria was significantly associated with long-term death, after adjustment for potential confounding risk factors (HR=1.92, p=0.012). Conclusions Pre-TEVAR proteinuria was identified as a prognostic marker in patients with TBAD and has potential for application as a convenient and simple risk assessment method before TEVAR.

Chronic headache sufferers (N = 133) were assessed for Type A behaviour pattern using the Jenkins Activity Survey (JAS). The Type A score frequency distribution for all headache subjects combined, and each headache type separately were examined. Median scores of the all subjects combined group fell into the indeterminate range of Type A scores, that is, neither Type A or Type B. This was also the case for migraine and tension sufferers. Mixed subject's scores fell into the range of scores usually classified as Type A. Forty-five percent of the mixed subjects fit the criteria for Type A behaviour pattern. Follow-up bivariate and multivariate analysis using J AS subscale scores as independent predictors and headache activity scores, from daily diaries, as dependent variables revealed only three correlations which approached significance. These results argue against a clear linear relationship between chronic headache and Type A behaviour pattern. There may be some utility in this construct when differentiated by headache type.

Abstract Background Both ABO blood group antigens and pathogenic immunoglobulin A1 (IgA1) in patients with IgA nephropathy (IgAN) are influenced by modifications of N-acetylgalactosamine and galactose. The purpose of this study was to assess whether ABO blood type is associated with galactose-deficient IgA1 (Gd-IgA1) in the progression of kidney disease in patients with IgAN. Methods We enrolled 1313 IgAN patients with a median of 44 months follow-up and measured the plasma Gd-IgA1 levels. Multivariate Cox regression models were used to estimate the association between all variables and adverse outcomes. Using the propensity score matching method, 718 IgAN patients with blood type either A or B were selected, and their data were used to assess the association of blood type and Gd-IgA1/serum complement 3 (sC3) with outcomes. Results We found that the risk of adverse outcomes was significantly higher in patients with blood type A than in those with type B (hazard ratio = 1.82, 95% confidence interval 1.23–2.71; P = 0.003) after multivariate adjustment. The Gd-IgA1 levels showed trends similar to the multivariate-adjusted event-free curves for the blood types. However, this higher risk of adverse outcomes in type A than in type B patients was no longer significant after the addition of Gd-IgA1/sC3 to the model. Conclusions IgAN patients with blood type A had a higher risk of adverse outcomes than those with type B, and this risk was associated with Gd-IgA1/sC3. Thus, the ABO blood type may provide a reference for the prognostic factors for individuals with IgAN.
