Spinal diffuse midline glioma: An unusual case presentation

Primary spinal cord neoplasms are rare, accounting for 1% of paediatric central nervous system tumours. The majority of which are low-grade gliomas (LGG). A teenage male presented with rapidly progressive lower limb paralysis. He subsequently underwent a near-total resection of an intramedullary thoracic tumour. Although the initial histopathology report suggested a LGG, closer review of the morphology and immunohistochemical staining revealed a diffusely infiltrating high-grade astrocytoma. Methylation profiling later confirmed a H3K27M-mutated spinal DMG. He underwent spinal radiation to the tumour bed soon after surgery but succumbed to his disease 8 days after completing radiation, and 3 months after presentation.Conclusion: Spinal DMGs are rare, can lead to diagnostic challenges and have a poor prognosis.

Surgical management of traumatic spondyloptosis: a case series

BackgroundTraumatic spondyloptosis is a rare and severe spinal injury characterized by complete anterior translation of one vertebra over another, often resulting in debilitating neurological deficits.Case presentationWe present two cases of traumatic spondyloptosis and elaborate on the clinical presentation, management, and follow-up improvement. The first case is a 30-year-old Nepalese man who sustained traumatic spondyloptosis following a blunt force injury to his back while engaged in tree-cutting activities. The patient presented with severe back pain, left lower limb paralysis, and neurological deficits (consistent with American Spinal Injury Association grade C). Radiographic evaluation revealed total anterior dislocation of the L4 vertebral body over L5, accompanied by fractures of the superior endplates of both vertebrae. The second case is a 35-year-old Nepalese female who presented with back pain and lower limb paralysis following a fall from a 300-m cliff, exhibiting tenderness and ecchymosis in the mid-back region. Radiological examination revealed D12 vertebra translation over L1 with fracture, categorized as American Spinal Injury Association grade A. Both cases were surgically managed and stabilized.ConclusionThese cases emphasize the importance of a comprehensive approach to trauma management as well as prompt recognition, and early surgical management in optimizing outcomes for patients with traumatic spondyloptosis.

Structural Design and Experimental Analysis of the Self-Balancing Lower Limb Exoskeleton Robot

To facilitate walking rehabilitation training for individuals with lower limb paralysis, a self-balancing exoskeleton robot with 12 degrees of freedom was conceived. The principal structural design was conducted in line with the biomechanics of the human lower limbs, and a kinematic model was formulated. The stipulated gait was resolved by reverse kinematics in MATLAB to derive the joint angle actuation curves. These curves served as the motive input in ADAMS kinematic simulation experiments, yielding a gait trajectory with an error margin of less than 2 mm compared to the prearranged gait, which is within a reasonable range of deviation. Experiments involving walking with the exoskeleton were also executed. The analysis of the six-axis force sensor data from the sole demonstrated that the ground reaction force curve consistently remained within the bounds of the foot’s support area, substantiating the exoskeleton’s capability for stable ambulation with a load. The simulations and walking experiments together verified the soundness of the exoskeleton’s structural design.

Clinical characteristics analysis of 24 cases of pediatric MOG antibody-associated diseases

ObjectiveTo investigate the clinical characteristics of children with myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD). MethodsA retrospective analysis was conducted on the clinical data, antibody tests, imaging, and factors associated with recurrence in 24 children diagnosed with MOGAD at Wuxi Children's Hospital from December 2017 to December 2023. ResultsAmong the 24 included children, the clinical characteristics at the onset of the first episode included fever (12 cases), headache (8), decreased vision (7), drowsiness (6), convulsions (5), ataxia (3), paralysis of both lower limbs (2), urinary and fecal incontinence (2), and central facial palsy (1). Among them, one case started with paralysis of both lower limbs and urinary retention, and electromyography suggested the involvement of peripheral nerves, leading to the diagnosis of MOG antibody-associated central and peripheral demyelinating syndrome (MOGAD-CCPD). Cranial MRI abnormalities were observed in 20 children, and spinal MRI abnormalities were noted in 6 children. All children responded well to corticosteroids and intravenous immunoglobulin, but 7 children experienced a relapse. Among them, 3 children achieved disease control after the addition of mycophenolate mofetil (CellCept), with no further relapses observed during follow-up. ConclusionThe disease course of MOGAD can be monophasic or relapsing. Most children have a good response to acute phase treatments. For those who relapse, immunosuppressants can be added as maintenance therapy, and the clinical prognosis is generally good. This article reports the first highly rare case in China of MOGAD-CCPD in childhood, suggesting that MOG IgG may serve as a potential biomarker associated with CCPD.

Generation of hereditary spastic paraplegia patient-derived induced pluripotent stem cell line UJSi003-A

Hereditary spastic paraplegia (HSP) is a rare neurodegenerative disorder with the predominant clinical manifestation of spasticity in the lower extremities. Patients with HSP experience spastic paralysis in both lower limbs, leading to progressive walking difficulties, increased reflexes, spasms, and extensor plantar responses. We successfully generated induced pluripotent stem cells (iPSCs) from peripheral blood mononuclear cells (PBMCs) obtained from a patient diagnosed with HSP. The iPSCs exhibited a normal karyotype, expressed pluripotency markers, and differentiated into the three germ layers in vitro.

Rehabilitation report of 2 cases of spinal cord ischemic injury after intra-aortic repair.

Spinal cord ischemia injury is a serious complication after intra-aortic surgery, with a low incidence but high disability rate. However, patients often do not receive comprehensive treatment in the early stages of the disease. Therefore, active neurological intervention is needed to protect and prevent spinal cord ischemia during and after surgery. In this paper, rehabilitation program and imaging data of 2 cases with spinal cord ischemic injury are presented and discussed regarding causes, prevention and acute treatment with this disease, which could be referred by clinicians. Case report 1: A 69-year-old male patient underwent aortic arch aneurysm and thoracic endovascular aortic repair (coated stent) was performed under general anesthesia. Complete paralysis of both lower limbs, constipation, and urinary retention occurred after surgery and was subsequently referred to our rehabilitation department. Case report 2: A man aged 41 years experienced sudden chest pain with no dizziness or headache. Weakness of both lower limbs gradually appeared over 30 minutes with subsequent loss of consciousness. He was diagnosed with aortic dissection and underwent aortic stent implantation. Inpatient rehabilitation began systematically 3 months after discharge. The 2 patients were diagnosed with paraplegia and spinal cord ischemic injury. The patients received strength and transfer training, sensory input, health mission, and activities of daily living. Patient 1 returned home without assistive devices and patient 2 returned home with wheelchair. Perioperative spinal cord protection is directly related to postoperative quality of life. Once the symptoms of spinal cord ischemic injury occur, cerebrospinal fluid drainage should be performed as soon as possible to increase mean arterial pressure. At the same time, methylprednisolone, ganglioside, anticoagulation, vasodilator drugs, and symptomatic supportive treatments are required. Intercostal artery and subclavian artery are reconstructed if necessary. Symptom stability flags referral to commence rehabilitation. Repetitive functional training is necessary to help patients return to the family and society as soon as possible.

Retrospective Analysis of Paraparalysis/Paraparesis Post Aortic Aneurysm Endovascular Repair

Abstract Objective Paralysis post TEVAR is a challenging complication, this study discusses its incidence, Risk factors, clinical outcome, reversibility, protective strategy and associated mortality. Methods Retrospective study Conducted on patients underwent thoracic and thoracoabdominal aortic Aneurysm Endovascular Repair in Last 11 years (January 2012 till June 2022) in single center as regard incidence, personal history, medical and surgical risk factors, preventive strategies, reversibility of paralysis and associated mortality. Data was obtained from records; paralysis was diagnosed through clinical examination immediately after emergence from anesthesia and frequently post operatively in SICU or even word and after discharge in follow-up outpatient clinic visits. Results A study carried on 137 patients, 15 patients of them developed lower limb paralysis with incidence of 10.9%, 3 patients of them (23.1%) developed paralysis immediately post operative, 4 patients developed paralysis in day 1 post operative (30.8%). And the rest of patients developed delayed onset paralysis (more than 24 Hour post procedure), The latest one developed paralysis 26 days post operative, 8 of paralyzed patients had spinal cord imaging (MRI) 4 of them (50%) didn’t show any abnormality and 3 of them (37.5%) showed spinal cord ischemia and 1 patient didn’t tolerate the MRI machine so the study was discontinued. According to reversibility, 9 patients had complete reversal of their motor and sensory symptoms to the baseline preoperative status. 2 patients had partial reversal of their symptoms, and 4 patients had persistent symptoms without any improvement despite the routine management that included elevating MAP and draining CSF to less than 10 mmHg in order to maintain spinal cord perfusion pressure at level of 80 mmHg and giving naloxone. Data showed 12 out of 81 patients (14.8%) who had functioning spinal drain developed paralysis. Duration of procedure is the most affecting risk factor on paralysis, patients with mean duration of 270 minutes had higher risk of paralysis. Conclusion Prediction of paralysis post TEVAR is still difficult and data analysis showed that the duration of procedure is the only statistically significant variable that we can rely on.

E048 Spinal gout: an unusual cause of paraplegia

Abstract Background/Aims Gout is a common inflammatory arthritis caused by the deposition of monosodium urate crystals. Gout usually causes peripheral joint arthritis. Axial involvement is likely under-recognised, affecting an estimated 10-20% of gout patients. Spinal gout is an established phenomenon in patients with chronic tophaceous gout and sustained hyperuricaemia. Gout can affect any segment of the spine. Clinical presentation of spinal gout is variable including back pain, radiculopathy and cord compression. Due to its nonspecific presentation, it can be confused for other spinal pathologies such as epidural abscess, malignancy, spondylodiscitis and vertebral osteomyelitis. Methods We present a case report of a young male with tophaceous gout of the thoracic spine. Results A 37 year old man presented with 4 day history of acute thoracic back pain followed by flaccid lower limb paralysis. He was morbidly obese (BMI 60) and had a 13-year history of poorly controlled gout with most recent uric acid being 627. He had previously declined urate lowering therapy but commenced allopurinol treatment one month prior to admission. On examination power was 0/5 in both lower limbs with absent reflexes and a T12 sensory level. MRI showed multi-level facet joint arthropathy. An epidural collection was present at T8-10, causing complete occlusion of the vertebral artery. He underwent an urgent posterior thoracic decompression. ‘White cheese like epidural pus’ was removed and he was initially treated as facet joint infection. He had ongoing fevers [>38.5C], despite empirical antibiotics, and C-reactive-protein was persistently elevated [highest at 360mg/L]. Uric acid was 423. Enrichment culture of the epidural collection and serial blood cultures were negative. Repeat MRI of spine did not demonstrate any reoccurrence of collection. Subsequently the histology of the epidural collection was reported as characteristic of gout with ‘amorphous material and giant cells’. No urate crystals were identified as the sample was prepared with formalin, which would have dissolved any crystals present. He was referred to rheumatology who identified synovitis in his hands, wrist and elbows, consistent with active polyarticular gout. There were small tophi present on his heels and pinna. The patient was commenced on oral prednisolone and allopurinol was rapidly up-titrated. Unfortunately, the patient did not recover neurological function. Conclusion We present a unique case of acutely presenting tophaceous thoracic spinal gout causing irreversible paraplegia in a young patient, mimicking an epidural abscess. Our patient had hyperuricaemia for over 10 years without treatment, raising his risk of axial complications. A high index of suspicion for spinal gout is needed for patients presenting with acute back pain and neurological symptoms with a history of chronic gout. This case highlights diagnostic challenges in identifying spinal gout and the importance of treating tophaceous gout early to prevent devastating long-term complications. Disclosure C.A.

Structural design and research of a novel lower limb rehabilitation robot for human–robot coupling

A bedside rehabilitation robot is developed to address the challenge of motor rehabilitation for patients with lower limb paralysis. Firstly, based on the principles of physical rehabilitation, a two-link planar robot model is used to simulate both the robot and human lower limbs, and the coupling characteristics between the human and robot are thoroughly analyzed. Then, the lower limb rehabilitation robot, fitted with an end-effector and ankle wearable feature, is designed according to the structural parameters. To enhance patient safety during rehabilitation, the device incorporates a freely rotating leg support mechanism that reduces the load on the ankle due to gravitational forces, and a two-stage series elastic mechanism is integrated below the foot support to provide a passive compliant output of robot power, allowing for more natural movement and reducing the risk of injury. Secondly, dynamic modeling is used to determine the dynamic parameters of the robot by conducting simulation calculations based on the inertia parameters of the human body and the robot model design parameters. Finally, an experimental platform is established using the structural and dynamic parameters, and the robot’s reliability is validated through experimentation. Results indicate that the robot can accurately complete passive rehabilitation training tasks, and the dynamic parameters meet the expected requirements.

Lower Limb Paralysis Associated with Chikungunya in Kinshasa, the Democratic Republic of the Congo: Survey Report.

Polio-associated paralysis is one of the diseases under national surveillance in the Democratic Republic of the Congo (DRC). Although it has become relatively rare due to control measures, non-polio paralysis cases are still reported and constitute a real problem, especially for etiological diagnosis, which is necessary for better management and response. From September 2022 to April 2023, we investigated acute flaccid paralysis (AFP) cases in Kinshasa following an alert from the Provincial Division of Health. All suspected cases and their close contacts were investigated and sampled. Among the 57 sampled patients, 21 (36.8%) were suspects, and 36 (63.2%) were contacts. We performed several etiological tests available in the laboratory, targeting viruses, including Poliovirus, Influenza virus, SARS-CoV-2, Enterovirus, and arboviruses. No virus material was detected, but the serological test (ELISA) detected antibodies against Chikungunya Virus, i.e., 47.4% (27/57) for IgM and 22.8% (13/57) for IgG. Among suspected cases, we detected 33.3% (7/21) with anti-Chikungunya IgM and 14.3% (3/21) of anti-Chikungunya IgG. These results highlight the importance of enhancing the epidemiological surveillance of Chikungunya.

A Rare Case of Postpartum Paraplegia: A Case Report

ABSTRACT In this case report, a 27-year-old woman who had pre-eclampsia in the past and had a cesarean section as a result of the condition presents with an uncommon and difficult form of postpartum paraplegia. She experienced bilateral lower limb paralysis and urine incontinence soon after the surgery, which quickly led to unconsciousness and required mechanical ventilator support and intensive care treatment. Comprehensive diagnostic testing, which included magnetic resonance imaging scans of the brain and spinal cord, identified signs typical of “Posterior Reversible Encephalopathy Syndrome (PRES)” and spinal cord infarction affecting segments C3 to D2. “Antiphospholipid Antibody Syndrome (APLA)” was identified by laboratory testing, highlighting the significance of taking a thorough approach to comprehending this uncommon clinical condition. Treatment included anticoagulant therapy, high-dose steroid therapy, and antihypertensive drugs, emphasizing the crucial importance of inter-disciplinary care in handling such complex situations. Even if the patient’s symptoms have partially improved, their condition is still being closely monitored in the intensive care unit. In the context of postpartum neurological problems and the complex interplay between pre-eclampsia, spinal cord infarction, and related clinical symptoms, this case emphasizes the need for increased awareness and prompt management.

Development and Performance Evaluation of a Smart Upper-Limb Rehabilitation Exercise Device.

User-friendly rehabilitation medical devices can enhance health and the quality of life through the convergence of information communication and medical technology. Muscle contraction enables bodily movement, and the assessment of muscle strength is crucial. Muscle contraction includes isometric, isotonic, and isokinetic types. Many individuals with physical disabilities rely on wheelchairs due to lower-limb paralysis. There is a substantial correlation between the level of upper-limb functional recovery and the quality of daily life. This study aimed to design and evaluate a device that utilizes various muscle contractions to enhance the effectiveness of upper-limb rehabilitation exercises. The results from the isometric performance assessment showed percentage error rates of >30% for 5-30 kg. Correction equations were employed, and the isometric performance assessment resulted in error rates below 2.1% for 5-30 kg. Isokinetic performance assessment using video analysis evaluated a consistent wire speed from 10 cm/s to 70 cm/s with an average error rate of 0.91% across all speeds. This study demonstrates the ability to accurately measure various muscle contractions and showcases the potential for real-time feedback. This highlights how such a device could be helpful for target groups, including older adults and individuals with disabilities, during upper-limb rehabilitation exercises.

Electroacupuncture for acute transverse myelitis following viral infection: A case report

BackgroundElectroacupuncture (EA) has a positive effect on neurological repair and functional recovery following spinal cord disease. However, evidence of its effectiveness in acute transverse myelitis (ATM) cases is limited. Patient presentationA 48-year-old woman experienced headache and fever for 5 days, followed by a sudden onset of back pain, lower limb paralysis, and urinary and bowel dysfunction. The patient received intravenous medications. However, she did not experience improvement in clinical symptoms. She subsequently underwent acupuncture treatment. She regained walking ability and experienced improved bladder function and bowel control after 36 sessions of EA treatment. MethodsCARE guidelines informed the case study report. The MRC and ICIQ-UI-SF scores were used to verify changes in lower-extremity muscle strength and urination after EA treatment. Qualitative information was collected using feedback tables. ConclusionPharmacological treatment for ATM lacks clear advantages because of its complex pathophysiological mechanisms. Hence, EA could be recommended as a promising treatment modality for ATM.

Suspected Cauda Equina Syndrome: Can the Presence of an Orthopaedic Doctor in the Emergency Department Reduce Waiting Times for MRI Scans and Inpatient Stays?

Introduction Cauda equina syndrome (CES) is a very rare but devastating surgical emergency that can lead to permanent bowel, bladder or sexual dysfunction and lower limb paralysis. Although it is a clinical syndrome, an MRI scan is a critical diagnostic investigation for these patients and should be done as soon as possible. Our hospital is a district general hospital with no spinal services on site. There is a protocol in place for the management of these patients locally with MRI scanning during daytime hours. However, if the patient presents after 8 pm, they are discussed with the tertiary spinal centre, which then advises if the patient requires transfer overnight for urgent scanning.Considering an MRI scan is a critical diagnostic step for these patients,we introduced a role for an orthopaedic doctor in the Emergency Department (ED) to assess all of these patientsbefore collecting data for the second cycle. The aim of this audit was to see the effect of having an orthopaedic doctor in the ED for the assessment of these patients and its impact on waiting times and admission rates. Methods A closed-loop audit cycle was done looking into all referrals to trauma and orthopaedics with acute back pain and suspected CES in a district general hospital with no spinal services on site. The first cycle was between September 30, 2020, and May 31, 2021, and included 93 patients in total. Following this, a role for an orthopaedic doctor in ED was introduced from December 1, 2021, to January 31, 2022, for assessment of these patients. Data was then collected retrospectively for all patients referred during this period (n=36). Data was extracted from all relevant clinical systems including electronic patient record (EPR), Patient Pass (Patient Pass Ltd, Greater Manchester, England), which is the system used to digitally communicate with regional spinal services, and PACS (picture archiving and communication systems). The data was collated on a Microsoft Excel spreadsheet (Microsoft Corporation, Redmond, Washinton, United States) and analysed. Results Data were collected for a total of 36 patients in the second cycle following the introduction of an orthopaedic doctor in the ED. The age of patients referred was 30-89 yearswith a mean age of 51; 44.4% were male (n=16) and 55.5% female (n=20). All the patients who were referred received their MRI scan and report within 24 hours of presentation to the ED. In the first cycle of the audit, the mean waiting time for an MRI scan had been 12.5 hours, which was reduced to eight hours following the introduction of an orthopaedic doctor in the ED during daytime hours. This was stratified further according to the time patients presented to the hospital. From 8 am to 4 pm, the mean waiting time for an MRI scan was 9.5 hours pre-intervention and 5.5 hours after. From 4 pm to 12 am, the mean waiting timewas 18 hours before and 13 hours after, and from 12 am to 8 am, the waiting time for scans improved from 8.5 hours to 6.5 hours. The number of patients discharged on the same day greatly improved from 29% (n=27) in the initial study to 58% (n=21). This decreased unnecessary inpatient stays from 71% (n=66) to 42% (n=15). Conclusion This study showed that an orthopaedic doctor in the ED for the acute assessment of patients referred with possible CES is an effective way of improving their management. This decreases waiting times for MRI scans and therefore allows the patient to be managed more efficiently.

Profiles of patients with myelomeningocele admitted to the neonatal unit at Universitas Academic Hospital in Bloemfontein, South Africa


 
 
 
 Background. Myelomeningocele (MMC) is a common neural tube defect with significant sequelae. There are limited recent data on the mortality and morbidity of MMC in South Africa (SA).
 Objective. To describe the outcomes and characteristics of patients with MMC admitted to the neonatal unit at Universitas Academic Hospital (UAH) in Bloemfontein, SA.
 Methods. A retrospective, descriptive study which included 53 patients with MMC admitted to the neonatal unit between 1 January 2017 and 31 December 2019 was conducted. Electronic patient records were reviewed. Data included outcomes, length of stay, complications and maternal and infant characteristics.
 Results. The inpatient mortality rate was 11.3% (n=6/53). The median length of stay was 18 days. Notable MMC complications included hydrocephalus (88.7%; n=47/53), Chiari malformation type II (44.7%; n=21/47), lower-limb paralysis (84.9%; n=45/53), lower-limb deformities (60.4%; n=32/53), meningitis (52.8%; n=28/53), neuropathic bladder (37.7%; n=20/53) and loss of anal tone (41.5%; n=22/53). MMC repair was performed in 62.2% (n=33/53) and 27.3% (n=9/33) developed complications. Wound sepsis and breakdown were the most common complications (18.2%, n=6/33), with a median 8 days to complications. Antenatal sonar was not performed in 62% (n=31/50) of cases. MMC was detected antenatally in 20% of cases.
 Conclusion. The inpatient mortality rate in thisstudy was lower than the mortality rates reported in other low- and middle-income countries although significant morbidity was identified. A lack of quality antenatal care and access to antenatal sonars were barriers to early detection of MMC. Other healthcare system infrastructural failures may be contributory, which highlights the need for ongoing inter- sectoral collaboration for prevention, early detection and management of MMC to improve patient outcomes.
 
 
 

Clinical efficacy of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in the treatment of II° lumbar isthmic spondylolisthesis: A retrospective cohort study.

Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) is not suitable for high-grade isthmic spondylolisthesis, whether MIS-TLIF can treat II° lumbar isthmic spondylolisthesis (IS) is still controversial. This retrospective cohort study compared the clinical efficacy of MIS-TLIF and open transforaminal lumbar interbody fusion (OPEN-TLIF) in the treatment of II° lumbar IS. From January 2017 to January 2023, 101 patients with II° lumbar IS were diagnosed in our hospital and underwent surgical treatment, of which 53 received MIS-TLIF surgery and 48 received OPEN-TLIF surgery. The operation time, blood loss and surgical complications were compared between the 2 groups. The pain, function, reduction rate and fusion rate of the patients were evaluated during follow-up. The amount of intraoperative blood loss, postoperative drainage, and postoperative hospital stay in the MIS-TLIF group were significantly lower than those in the OPEN-TLIF group were (P < .01). In the MIS-TLIF group, there were 1 case of dural sac injury and 3 cases of lower limb paralysis. The complication rate of MIS-TLIF was lower than the OPEN-TLIF group (P = .032). In the visual analog scale score of low back pain, the MIS-TLIF group was lower than the OPEN-TLIF group after operation and at the last follow-up. There were no significant differences in postoperative leg pain score, slippage rate, and fusion rate between the 2 groups. Compared with OPEN-TLIF, MIS-TLIF has the advantages of better low back pain relief, less trauma, less bleeding and faster recovery, and is worthy of clinical promotion.

An Anatomical Exploration of Kukundra Marma

Abstract: Out of 107 Marma, Kukundar Marma is one that is classified as Vaikalyakara Marma and is situated on the Parshava Bhirbhage (dorso-lateral region of the pelvis) and Pristhvansa Ubhayato (both sides of the vertebral column). Injury to the Kukundar Marma causes lower limb paralysis and a lack of feeling. It belongs to the category of Sandhi Marma and is intimately related to the sacroiliac joint. The majority of Kukundar Marma Aghatjanya Lakshana resembles sciatic nerve damage and lumbosacral plexopathy. Marma aghat lakshans can serve in this situation as predictors of the structures in question. This study used cadaveric research to determine the precise location of the Kukundar Marma and its relationship to other anatomical entities (in its circumference). The study concludes as a result

Stent Graft Collapse after Zone 0 Landing Thoracic Endovascular Aortic Repair.

A zone 0 landing thoracic endovascular aortic repair was performed on a 69-year-old man with a saccular aortic arch aneurysm. Seven days after the surgery, the patient experienced diminished consciousness and lower limb paralysis. Stent graft collapse was seen on a computed tomography scan. Thereafter, the patient underwent total arch replacement and emergency stent graft removal.

A case of stent-assisted balloon-induced intimal disruption and relamination of distal remaining aortic dissection after the ascending aorta and aortic arch replacement for acute aortic dissection

BackgroundThe early survival rate of patients with acute type A aortic dissection (TAAD) has improved remarkably over the past two decades. However, a false lumen may remain after proximal aortic repair and is a potential risk factor for aortic diameter enlargement, aortic rupture, and death in the chronic phase. In the stent-assisted balloon-induced intimal disruption and relamination of aortic dissection (STABILISE) technique, a stent graft is implanted at the proximal part of the aortic dissection, followed by bare-metal aortic stent placement over the distal aortic dissection. Next, an aortic balloon catheter is dilated inside the stent graft and the bare stent to disrupt the intima and collapse the false lumen, immediately restoring uniluminal thoracoabdominal aortic flow. This report describes our experience with the STABILISE technique for a residual aortic dissection after an ascending aorta, and partial aortic arch replacement for acute TAAD resulted in complications.Case presentationA 60-year-old man presented to our hospital with chest pain, paresthesia, and left lower-limb paralysis. He was diagnosed with acute type A aortic dissection (TAAD) and malperfusion of the left lower limb by computed tomography (CT), and an emergent ascending aorta and partial aortic arch replacement were performed. Immediately after surgery, the left femoral arterial pulse improved, and left lower limb revascularization was deferred. The postoperative course was good; however, back pain and intermittent claudication recurred on the 9th day after surgery. A CT examination revealed persistent antegrade false lumen flow in the descending thoracic aorta through the left subclavian artery dissection and retrograde false lumen flow from the thoracoabdominal segment, resulting in aortic diameter enlargement and narrowing of the true lumen. The symptoms did not improve, and the STABILISE technique was performed on the 12th day after the initial aortic surgery. The patient’s subsequent course was good; the back pain and intermittent claudication resolved. The patient was discharged on the 8th day after the STABILISE technique.ConclusionsThe STABILISE technique can obliterate the false lumen and resolve symptoms associated with a residual false lumen after proximal aortic repair for acute TAAD.
