Good Clinical Outcome

SummaryTriple pelvic osteotomy (TPO) was used to treat a selected group of young dogs with clinical and radiographic signs of hip dysplasia. Good clinical outcomes have been reported in dogs between 17–85 kg body weight. Hip dysplasia however is also en-countered in smaller dogs. If surgery is performed in smaller dogs, femoral head and neck ostectomy is the main treatment method used. We wanted to determine if TPO could also be used in dogs under 12 kg bodyweight. Our study showed that it is technically possible to perform TPO surgery in dogs less than 12 kg of weight (down to 4.6 kg) with a good clinical outcome even in hips with high angles of reduction and subluxation.

SummaryThe efficiency of conservative treatment, excision arthroplasty of the femoral head and neck and triple pelvic osteotomy for the treatment of hip dysplasia in the immature dog were compared using locomotor, physical and radiographic examinations and owner’s evaluation. Cases selected for this study were dogs diagnosed with bilateral hip dysplasia, initially admitted with clinical signs (lameness, pain), immature at the beginning of the treatment (less than 12 months of age), with both hips subjected to the same treatment (conservative treatment, excision arthroplasty of the femoral head and neck or triple pelvic osteotomy). These dogs never showed any musculoskeletal problems other than hip dysplasia and the surgical treatment had been completed at least 20 months prior to re-evaluation time. Fourteen hips were re-evaluated in the conservative group, 16 in the triple pelvic osteotomy group and ten in the excision arthroplasty group. Locomotor, physical and owner’s evaluations demonstrated the superiority of the triple pelvic osteotomy. These evaluations also showed that excision arthroplasty was more efficient than conservative treatment. Radiographic examination demonstrated the obvious superiority of the triple pelvic osteotomy over conservative treatment.Locomotor, physical and owner’s evaluations demonstrated the superiority of the triple pelvic osteotomy over conservative treatment and excision arthroplasty for the treatment of hip dysplasia in the immature dog. Radiographic examination demonstrated the obvious superiority of the triple pelvic osteotomy over conservative treatment for joint congruence and control of degenerative joint disease.

Aspiration Technique

Background: Mechanical thrombectomy is the standard therapy in patients with acute ischemic stroke (AIS). The primary aim of our study was to compare the procedural efficacy of the direct aspiration technique, using Penumbra ACETM aspiration catheter, and the stent retriever technique, with a SolitaireTM FR stent. Secondarily, we investigated treatment-dependent and treatment-independent factors that predict a good clinical outcome. Methods: We analyzed our series of mechanical thrombectomies using a SolitaireTM FR stent and a Penumbra ACETM catheter. The clinical and radiographic data of 76 patients were retrospectively reviewed. Using binary logistic regression, we looked for the predictors of a good clinical outcome. Results: In the Penumbra ACETM group we achieved significantly higher rates of complete vessel recanalization with lower device passage counts, shorter recanalization times, shorter procedure times and shorter fluoroscopy times (p < 0.001) compared to the SolitaireTM FR group. We observed no significant difference in good clinical outcomes (52.4% vs. 56.4%, p = 0.756). Predictors of a good clinical outcome were lower initial NIHSS scores, pial arterial collateralization on admission head CT angiography scan, shorter recanalization times and device passage counts. Conclusions: The aspiration technique using Penumbra ACETM catheter is comparable to the stent retriever technique with SolitaireTM FR regarding clinical outcomes.

Fluid Attenuated Inversion Recovery

Background and purpose: Fluid-attenuated inversion recovery (FLAIR) vessel hyper-intensities (FVH) have been hypothesized to have a positive correlation with good collaterals and more favorable clinical outcomes in acute stroke patients. We assessed if FVH predict the Target mismatch profile (TMM) and clinical outcomes in the DEFUSE studies. Methods: Patients with technically adequate baseline diffusion weighted images (DWI), perfusion images (PWI), and FLAIR images were included in this pooled analysis of the DEFUSE 1 and 2 studies. The FVH sign was defined as visible hyper-intense vessels on FLAIR images and assessed at basal ganglia levels by two independent raters. Clinical outcomes were assessed using modified Rankin Scale (mRS) at 90 days. The Target mismatch profile was based on baseline DWI and PWI volumes using automated software (RAPID). Results: Seventy seven patients met the inclusion criteria. Median time (IQR) from symptom onset to baseline MRI was 4.6 hours (3.9 - 5.4) and median (IQR) DWI lesion was 13.1 (5.0 - 32.0) ml. Of these, 66 patients (86%) had the FVH sign. Kappa score for inter-rater agreement was 0.621 (95CI: 0.33 - 0.91). Seventy (74%) cases with FVH had TMM profile vs. 33% of No FVH patients (p=0.023). Good clinical outcome (mRS 0-2) did not differ (50% with FVH vs. 73% without FVH, p=0.203). Only 38% of the patients with FVH had good angiographic collaterals and the rate of early reperfusion did not differ (45% with FVH vs. 25% without FVH, p=0.45). Conclusions: FVH is common in acute stroke patients (86%) and is associated with the Target Mismatch profile. However, FVH was not associated with favorable angiographic collaterals, good clinical outcome or early reperfusion in the DEFUSE 1 and 2 cohorts.

Canine Hip Dysplasia

Simultaneous bilateral femoral head and neck ostectomy (FHO) was performed on 15 dogs for severe bilateral hip dysplasia. A follow-up survey was performed 6 to 48 months after surgery to assess the postoperative recovery and activity levels of the operated dogs. All dogs had normal activity levels and were pain free according to their owners. Owner satisfaction regarding the outcome of the surgery was high. Simultaneous bilateral FHO was a viable surgical option for the treatment of painful bilateral hip disease in dogs, especially when other surgical options were not indicated or were cost prohibitive.

Chiari Pelvic Osteotomy

Chiari pelvic osteotomy is a surgical procedure having been performed for almost sixty years in patients with the insuffcient coverage of the femoral head. It is most frequently used in young patients with dysplastic acetabular sockets as a part of developmental hip dysplasia. Even though performance of the Chiari osteotomy is associated with positive therapeutical results, above all, its main goal is to delay inevitable degenerative changes. Original surgical technique has been modified and improved over time. Nevertheless, the basic idea has remained unchanged - increasing of the femoral head coverage by medial displacement of the distal part of the pelvis along with capsular interpositioning. Given the complexity of operation, the complication percentage is rather low. Chiari pelvic osteotomy has lost its actuality and importance during this past six decades. The role of Chiari pelvic osteotomy has been considerably taken over by other more efficient and more lasting surgical procedures. Nonetheless, Chiari pelvic osteotomy is still present in modern orthopedic practice, above all as ?salvage? osteotomy.

SummaryTriple pelvic osteotomy (TPO) was used in the treatment for traumatic coxofemoral luxations in four adult, large breed dogs with hip dysplasia. Initial closed reductions failed in three and one dog had an initial closed reduction and subsequent open reduction of the coxofemoral luxation that failed. Hip dysplasia was thought to be a prominent factor contributing to the reluxation. TPO successfully maintained reduction of the coxofemoral luxation in all of the dogs. An increase in dorsal acetabular coverage of the femoral head following TPO was demonstrated by an increased Norberg angle. The improved congruency was thought to maintain reduction of the femoral head in the acetabulum and decrease stresses on the joint capsule, allowing healing to occur. Long-term (median: 343, mean ± SD: 406 ± 226 days follow-up) function of the affected limb was comparable to the contralateral limb. Three of the four dogs did not have radiographic progression of coxofemoral degenerative joint disease of the affected joint and differences in the progression of degenerative joint disease were not evident between the affected and the contralateral coxofemoral joint. A decrease in abduction and external rotation and an increase in internal rotation following TPO was noted in the affected coxofemoral joint. Our results establish the utility of this procedure in dysplastic dogs with traumatic coxofemoral luxations.Triple pelvic osteotomy used in the treatment for traumatic coxofemoral luxation in four adult, large breed dogs with hip dysplasia successfully maintained reduction and resulted in satisfactory limb function in all patients.

Mean Time

Introduction: Previous studies suggested that faster times to recanalization led to better clinical outcomes in patients after endovascular thrombectomy. Hypothesis: We assessed the hypothesis that an association between time to recanalization and clinical outcomes depends on cerebral blood volume (CBV) obtained from pre-treatment CT perfusion (CTP). Methods: In consecutive patients with acute ischemic stroke who were obtained successful recanalization (TICI 2A-3) by endovascular thrombectomy for internal carotid artery or middle cerebral artery M1 occlusion, we retrospectively analyzed the influence on clinical outcome of time to recanalization and relative CBV value (rCBV) evaluated by pre-treatment CTP. The patient population was divided into 3 groups according to rCBV: severe decreased rCBV group (rCBV <0.6), mild decreased rCBV group (rCBV 0.6 to 0.9) and normal rCBV group (rCBV >0.9). In each group, we compared time to recanalization from onset and CTP between good clinical outcome group (modified Rankin Scale score ≤2 at day 90) and poor clinical outcome group (modified Rankin Scale score ≥3). Results: Fifty-seven patients were eligible for this study. The mean age was 75.3 years and median baseline NIHSS was 17. Nineteen patients (33.3 %) achieved good clinical outcome. In the severe decreased rCBV group, mean time to recanalization from onset and CTP were 192 and 115 minutes, respectively, but no patient had a good clinical outcome. In the mild decreased rCBV group, mean time to recanalization from onset (180 versus 311 minutes, p=0.034) and CTP (102 versus 169 minutes, p=0.007) were significantly shorter in the good clinical outcome group. In the normal rCBV group, no association was found between clinical outcome and time to recanalization from onset (311 versus 313 minutes) and CTP (177 versus 184 minutes). Conclusions: Early successful recanalization resulted in better clinical outcome in patients with mild decreased rCBV. Severe decreased rCBV did not provide good outcome regardless of early successful recanalization.

The Impact

Background Recent trials support endovascular thrombectomy (EVT) in select patients beyond the conventional 6-hour window. Objective In this work, we estimate the impact of extended window EVT on procedural volumes and population-level clinical outcomes using Monte Carlo simulation. Methods We simulated extending EVT eligibility in a system comprising an EVT-incapable primary stroke center (PSC) and EVT-capable comprehensive stroke center (CSC) using routing paradigms that initially direct patients to (1) the nearest center, (2) the CSC, or (3) either CSC or nearest center based on stroke severity. EVT eligibility and outcomes are based on HERMES, DEFUSE-3, and DAWN studies in the 0-6, 6-16, and 16-24 hour windows, respectively. Probability of good clinical outcome is determined by type and timing of treatment using clinical trial data. Results Relative increase in EVT volume in the three tested routing paradigms was 15.7-15.8%. The absolute increase in the rate of good clinical outcome 0.4% in all routing paradigms. NNT for extended window EVT was 239.9-246.4 among the entire stroke population. Conclusion Extended window EVT with DEFUSE-3 and DAWN criteria increases EVT volume and modestly improves population-level clinical outcomes.
