RESUMO

OBJECTIVE: The aim of this study was to determine the incidence of pressure ulcers (PUs) in patients treated for acute ischaemic stroke (AIS) and to evaluate comorbid/confounding factors. METHOD: The study included patients treated for AIS who were divided into three treatment groups: those receiving intravenous tissue plasminogen activator therapy (tPA); patients receiving mechanical thrombectomy (MT); and those receiving both tPA and MT. PUs were classified according to the international classification system and factors that may influence their development were investigated. RESULTS: A total of 242 patients were included in this study. The incidence of PUs in patients treated for AIS was 7.4%. Most PUs were located on the sacrum (3.7%), followed by the gluteus (3.3%) and trochanter (2.9%). With regards to PU classification: 29% were stage I; 34% were stage II; and the remainder were stage III. Age was not a significant factor in the development of PUs (p=0.172). Patients in the tPA group had a lower PU incidence (2.3%) than patients in the tPA+MT group (15.7%) and MT group (12.1%) (p=0.001). Patients with PUs had a longer period of hospitalisation (18.5±11.92 days) than patients without a PU (8.0±8.52 days) (p=0.000). National Institute of Health Stroke Scale (NIHSS) scores at admission were higher in patients with PUs than in patients without a PU (14.33±4.38 versus 11.08±5.68, respectively; p=0.010). The difference in presence of comorbidities between patients with and without PUs (p=0.922) and between treatment groups (p=0.677) were not statistically significant. The incidence of PUs was higher in patients requiring intensive care, but this difference was not statistically significant (p=0.089). CONCLUSION: In this study, patients treated for AIS with high NIHSS scores at admission and/or receiving MT were at higher risk for PUs, and so particular attention should be given to these patients in order to prevent PU development.

RESUMO

INTRODUCTION: Wide-necked bifurcation aneurysms pose significant challenges for endovascular treatment. A recent innovation, the stent plus balloon-assisted coiling technique, combines a stent and a balloon to address these aneurysms effectively. PURPOSE: To evaluate the safety and efficacy of the stent plus balloon-assisted coiling for the treatment of wide-necked bifurcation aneurysms. METHODS: We conducted a retrospective review of our endovascular database to identify patients who were treated with this technique and had a satisfactory angiographic follow-up of at least 24 months. Technical success, initial clinical and angiographic outcomes, procedural complications, and follow-up results were analyzed. Angiographic and clinical outcomes were assessed using Modified Raymond-Roy Classification and Modified Rankin Scale, respectively. RESULTS: Our study included 37 aneurysms in 36 patients (26 females) with a mean age of 56.6 years. Mean aneurysm and neck sizes were 7.3 ± 3.5 mm and 3.7 ± 1.0 mm, respectively. Technical success reached 97.2%, with an immediate occlusion rate of 65.7%. At a mean follow-up of 36.5 ± 9.7 months, final angiographic follow-up showed a 91.9% complete occlusion rate. Three aneurysms did not achieve complete occlusion; however, none required retreatment. Complications developed in 32.4% of the procedures. Mortality and morbidity rates were 5.4% and 2.7%, respectively. A good clinical outcome was observed in 91.9% of patients. CONCLUSION: Our results showed that stent plus balloon-assisted coiling technique allows good angiographic outcomes for wide-necked bifurcation aneurysms. However, overall complication rate is high. Subgroup analysis indicated promising safety and efficacy for MCA bifurcation aneurysms, suggesting this technique could be a valuable option for select aneurysms.

RESUMO

BACKGROUND: The safety and efficacy of mechanical thrombectomy (MT) for proximal large vessel occlusion after acute ischemic stroke (AIS) have been demonstrated. Clinical investigations of endovascular approaches for treating AIS due to M2 occlusions have been ongoing. PURPOSE: To assess the outcomes of M2 occlusions according to treatment modality and anatomical division. METHODS: A total of 113 consecutive M2 occlusions treated with endovascular treatment (EVT) at our tertiary stroke center between January 2019 and December 2022 were retrospectively analyzed. Patients were divided into three groups: mechanical thrombectomy (MT); intravenous thrombolysis plus MT (IVT + MT); and IVT alone. The primary outcomes were good prognosis (mRS = 0-2) and mortality (mRS = 6) on day 90. The secondary outcome was to determine the differences in outcomes between lesions in the superior and inferior branches of M2. RESULTS: In total, 55 (48.7%) patients underwent MT. In 42 (37.2%) patients, bridging IVT was performed with MT, and IVT alone was applied in 16 (14.2%) patients. Neither the prognosis at 90 days nor the mortality rate significantly differed among the groups. The outcomes did not significantly differ between occlusions in the superior and inferior branches of M2. CONCLUSION: MT was found to be safe and effective for treating M2 occlusions in this series.

RESUMO

PURPOSE: To compare outcomes of mechanical thrombectomy (MT) for acute ischemic stroke (AIS) in patients with atrial fibrillation (AF) taking warfarin or direct oral anticoagulants (DOACs). METHODS: A total of 71 consecutive patients with AF who underwent MT due to AIS between January 2018 and December 2021 were retrospectively analyzed. Patients were grouped as warfarin versus DOAC group. CHA2DS2-VASc, HAS-BLED, The National Institutes of Health Stroke Scale (NIHSS) at the time of admission and at 24 h, successful recanalization, post- MT complications and technical properties of MT were evaluated. Patients were divided into a good prognosis group, and a mortality group according to the 90th day mRS. RESULTS: HAS-BLED score was significantly higher in DOAC group (p = 0.006) There were no significant differences in stroke severity, successful recanalization rates, post-procedural complications and mRS 90th day scores between patients with warfarin and DOACs. CHA2DS2-VASc, NIHSS at admission and NIHSS on the 24th hour scores were significantly lower in the good mRS group (p = 0.012, p = 0.002, p < 0.001, respectively). CONCLUSION: MT is safe and effective in patients receiving warfarin or DOACs. HASBLED and CHA2DS2-VASc scores can help to predict functional outcome after MT.

RESUMO

Background: Currently, there is still no clear consensus on bridging thrombolysis (BT) before mechanical thrombectomy (MT). In this study, we aimed to compare clinical and procedural outcomes and complication rates of BT versus direct mechanical thrombectomy (d-MT) in anterior circulation stroke. Methods: A total of 359 consecutive anterior circulation stroke patients who received d-MT or BT in our tertiary stroke center between January 2018 and December 2020 were retrospectively analyzed. The patients were divided into two groups as Group d-MT (n = 210) and Group BT (n = 149). The primary outcome was the impact of BT on clinical and procedural outcomes, whereas the secondary outcome was the safety of BT. Results: The incidence of atrial fibrillation was higher in the d-MT group (p = 0.010). The median duration of the procedure was significantly higher in Group d-MT than in Group BT (35 vs 27 min, respectively; P = 0.044). The number of patients achieving good and excellent outcomes was significantly higher in Group BT (p = 0.006 and P = 0.03). The edema/malign infarction rate was higher in the d-MT group (p = 0.003). Successful reperfusion, first-pass effects, symptomatic intra-cranial hemorrhage, and mortality rates were similar between the groups (p > 0.05). Conclusions: In this study, BT seems to yield better clinical and procedural outcomes with lower complication rates than d-MT. These findings may support the additional value of intravenous alteplase in anterior system strokes. Further large-scale, prospective, randomized-controlled studies will clarify the gray lines in this consensus, but this paper is important for reflecting the real-world data in developing countries.

RESUMO

PURPOSE: The predicting bleeding complications in patients undergoing stent implantation and the subsequent dual antiplatelet therapy (PRECISE-DAPT) score predicts the risk of bleeding in patients with dual antiplatelet therapy (DAPT) after percutaneous coronary interventions (PCIs). Patients with carotid artery stenting (CAS) are also treated with DAPT. In this study, we aimed to investigate the performance of the PRECISE-DAPT score in predicting bleeding in patients with CAS. METHODS: Patients who had CAS between January 2018 and December 2020 were retrospectively enrolled. The PRECISE-DAPT score was calculated for each patient. The patients were divided into two groups based on their PRECISE-DAPT score: low < 25 and high ≥ 25. Bleeding and ischemia complications and laboratory data among the two groups were compared. RESULTS: A total of 120 patients with a mean age of 67.3 ± 9.7 years were included. Forty-three patients had high PRECISE-DAPT scores, and 77 patients had low PRECISE-DAPT scores. Six patients developed bleeding events during the six-month follow-up, and five of them were in the PRECISE DAPT score ≥ 25 group. The difference between the two groups regarding bleeding events at six months was significant (P = 0.022). CONCLUSION: The PRECISE-DAPT score might be used for predicting the bleeding risk in patients with CAS, and the bleeding rate was significantly higher in patients with a PRECISE-DAPT score ≥ 25.

RESUMO

BACKGROUND: The Low Profile Visible Intraluminal Support EVO (LVIS EVO) is a self-expandable braided stent, which was recently introduced for the treatment of intracranial aneurysms. Full visibility of the stent and a relatively high metal coverage ratio are the unique features of the LVIS EVO. OBJECTIVE: To assess the safety, efficacy, and midterm durability of LVIS EVO stent-assisted coiling for the treatment of wide-necked intracranial aneurysms. METHODS: The endovascular databases were reviewed to identify patients treated with LVIS EVO-assisted coiling. The technical success and immediate clinical/angiographic outcomes were assessed. Periprocedural and delayed complications were evaluated. The follow-up angiographic/clinical outcomes were investigated. The preprocedural/follow-up neurological statuses were assessed with the modified Rankin Scale. RESULTS: One hundred three aneurysms in 103 patients (63 females) with a mean age of 54.9 ± 11.3 years were included. The mean maximum sac diameter was 6.2 ± 2.9 mm. The procedural technical success rate was 100%. Immediate postprocedural angiography showed complete occlusion in 77.7%. The mean duration of the angiographic follow-up was 8.8 ± 3.6 months. Follow-up angiography showed complete aneurysm occlusion in 89% of the 82 patients with angiographic follow-up. Recanalization was observed in 7.3% of 82 patients. Two patients (2.4%) required retreatment. In addition, 8.7% of the patients had at least 1 complication, and 2.9% of the patients developed a permanent morbidity. All patients had mRS scores ≤2. CONCLUSION: The results of this study demonstrate that SAC with LVIS EVO is a relatively safe, efficient, and durable treatment for wide-necked and complex intracranial aneurysms.

RESUMO

ABSTRACT Introduction: The aim of this study is to present a series of six cases with thoracoabdominal aneurysm treated with hybrid technique in our center. Methods: Between May 2015 and December 2018, the data of six patients with thoracoabdominal aneurysms and various comorbidities who underwent visceral debranching followed by endovascular aortic aneurysm repair were reviewed retrospectively. Results: Patients' mean age was 65.3±19.6 years. All of them were male. Comorbidities were old age, congestive heart failure, coronary artery disease, chronic obstructive pulmonary disease, previous surgical interventions, and/or esophageal hemangioma. Except for one patient who underwent coronary artery bypass grafting (inflow was taken from ascending aorta), debranching was performed from the right iliac artery. Debranching of four visceral arteries (superior mesenteric artery, celiac trunk, and bilateral renal right arteries) was performed in three patients, of three visceral arteries (superior mesenteric artery, celiac trunk, right renal artery) was performed in one, and of two visceral arteries (superior mesenteric artery, celiac trunk) was performed in two patients. Great saphenous vein and 6-mm polytetrafluoroethylene grafts were used in one and five patients, respectively, for debranching. Endovascular aneurysm repair was performed following debranching procedures as soon as the patients were stabilized. In total, three patients died at the early, mid, and long-term follow-up due to multiorgan failure, pneumonia, and unknown reasons. Conclusion: Hybrid repair of thoracoabdominal aneurysms may be an alternative to fenestrated or branched endovascular stent grafts in patients with increased risk factors for open surgical thoracoabdominal aneurysm repair; however, the procedure requires experience and care.

RESUMO

BACKGROUND: Self-expandable stents have been increasingly used for endovascular treatment of intracranial aneurysms. Because the usage of intracranial stents has increased overall, total numbers of complications associated with these devices have increased. Thrombosis, distortion, or incomplete opening of stents are potential complications that may result in occlusion of the parent artery. In such cases, removal of the stent (stentectomy) may be the only solution to avoid serious clinical consequences. OBJECTIVE: To investigate the feasibility and efficacy of a novel stentectomy technique for removal of thrombosed self-expandable stents. METHODS: A retrospective review was performed of patients who underwent the stentectomy procedure. Initial and follow-up imaging and clinical outcomes were assessed. Immediate postprocedural and follow-up clinical statuses were assessed using the modified Rankin scale. RESULTS: Seven patients were included in this study (mean age: 54.1 years). The stentectomy was successful in 6 of 7 patients (85.7%). Seven stents in 6 patients were successfully removed to treat the acute in-stent thrombosis that was resistant to alternative bail-out treatments. The removed stents were self-expandable braided in 2 patients, flow diverters in 2 patients, and laser cut open-cell stents in 2 patients. Stentectomy failed to retrieve a thrombosed braided stent in 1 patient. The modified Rankin scale score of all patients who underwent a success stentectomy was ≤1. CONCLUSION: The stentectomy procedure using the defined technique is feasible to retrieve thrombosed stents and effective to restore the blood flow. It can be considered a last resort option to treat acute in-stent thrombosis resistant to alternative bail-out treatments.

RESUMO

AIM: We present our subclavian artery revascularization experiences in the patients with thoracic aortic aneurysm who underwent hybrid repair. MATERAIL AND METHODS: Between May 2015-December 2018,4 patients underwent TEVAR procedure following axilloaxillary bypass grafting.The mean age of the patients was 72.5 ± 3.01 years.One patient was female and 3 patients were male.Patients had thoracic aortic aneurysms including the left subclavian artery or aberrant right subclavian artery. RESULTS: All patients underwent endovascular stent graft repair following axilloaxillary bypass grafting in the same day.Mortality did not occur in the perioperative period.One patient had graft infection at 8th month of the operation and the graft was removed.He was lost due to pneumonia following the operation.The control computed tomographies of the other 3 patients revealed patent grafts together with successful endovascular interventions and they have been following uneventfully a mean of 27±6.2 months (range:24-32,median:29). CONCLUSION: The risk of stroke,spinal cord ischemia, and upper extremity ischemia are found higher in the patients who underwent coverage of the left subclavian artery without revascularization.The axilloaxillary bypass grafting may be performed in the patients with high risk to prevent carotid artery manipulation and clamping during carotid-subclavian bypass with long term promising patency rates.


OBJETIVO: Presentamos nuestras experiencias de revascularización de la arteria subclavia en los pacientes con aneurisma de aorta torácica sometidos a reparación híbrida. MATERIAL Y MÉTODOS: entre mayo de 2015 y diciembre de 2018, 4 pacientes fueron sometidos a TEVAR después de un injerto de derivación axiloaxilar. La edad media de los pacientes fue 72,5 ± 3,01 años. Un paciente era mujer y 3 pacientes eran varones. Los pacientes tenían aneurismas de la aorta torácica incluyendo el arteria subclavia izquierda o arteria subclavia derecha aberrante. RESULTADOS: Todos los pacientes fueron sometidos a reparación endovascular con endoprótesis vascular en el mismo día después de un bypass axiloaxilar, no hubo mortalidad en el perioperatorio, un paciente presentó infección del injerto a los 8 meses de la operación y se retiró el injerto, se perdió por neumonía Las tomografías computarizadas de control de los otros 3 pacientes revelaron injertos permeables junto con intervenciones endovasculares exitosas y han estado siguiendo sin incidentes una media de 27 ± 6,2 meses (rango: 24-32, mediana: 29). CONCLUSIÓN: El riesgo de ictus, isquemia medular e isquemia de la extremidad superior es mayor en los pacientes sometidos a cobertura de la arteria subclavia izquierda sin revascularización; en los pacientes con alto riesgo se puede realizar un bypass axiloaxilar para prevenir la manipulación de la arteria carótida. y pinzamiento durante la derivación carótido-subclavia con tasas de permeabilidad prometedoras a largo plazo.

RESUMO

BACKGROUND: The aim of this study was to assess the technical success and procedural safety of the new Silk Vista device (SV) by evaluating the intraprocedural and periprocedural complication rate after its use in several institutions worldwide. METHODS: The study involved a retrospective review of multicenter data regarding a consecutive series of patients with intracranial aneurysms, treated with the SV between September 2020 and January 2021. Clinical, intra/periprocedural and angiographic data, including approach, materials used, aneurysm size and location, device/s, technical details and initial angiographic aneurysm occlusion, were analyzed. RESULTS: 60 aneurysms were treated with SV in 57 procedures. 66 devices were used, 3 removed and 63 implanted. The devices opened instantaneously in 60 out of 66 (91%) cases and complete wall apposition was achieved in 58 out of 63 (92%) devices implanted. In 4 out of 66 (6%) devices a partial opening of the distal end occurred, and in 5 (8%) devices incomplete apposition was reported. There were 3 (5%) intraprocedural thromboembolic events managed successfully with no permanent neurological morbidity, and 4 (7%) postprocedural events. There was no mortality in this study. The initial occlusion rates in the 60 aneurysms were as follows: O'Kelly-Marotta (OKM) A in 34 (57%) cases, OKM B in 15 (25%) cases, OKM C in 6 (10%) cases, and OKM D in 5 (8%) cases. CONCLUSIONS: Our study demonstrated that the use of the new flow diverter Silk Vista for the treatment of intracranial aneurysms is feasible and technically safe.

RESUMO

Background/aim: In this study, we aimed to investigate what should be regarded as potential determinants of treatment strategies when evaluating 3D digital subtraction angiography (DSA) images. Material and methods: Our inclusion criteria were as follows: (1) presence of at least one intracranial aneurysm demonstrated by conventional angiography, (2) having both 2D and 3D images, and (3) being over 18 years old. First, two-dimensional (2D) and then 3D angiography images of 226 aneurysms of 150 patients were scanned. Morphological characteristics such as size, configurations, relationship with parent artery, baby counts, and other incidental findings were determined. Results: Of the 226 aneurysms, 11 (4.9%) were only detected on 3D images. Four of these 11 additional aneurysms were believed to be babies of other aneurysms seen in 2D images. Middle cerebral artery (MCA) M1 segment was the most common localization in terms of missed aneurysms. Of the 28 aneurysms located in the communicating segment of the internal carotid artery, the absolute locations of 7 (25%) could not be detected in 2D images or detected in the wrong location. Of the 24 aneurysms located in the ophthalmic segment, the origin of 8 (33%) could not be clearly identified in 2D images. Truncus relationships of MCAs bifurcation/trifurcation aneurysms were seen in 41 of 63 aneurysms (65%) on 2D images, whereas all were confirmed on 3D images. Fenestrations not seen in 2D images were identified in 3D images of 4 patients (3%). Conclusion: The superiority of 3D images compared to 2D images in determining the morphologic characteristics of intracranial aneurysms has been known for a long time. The contribution of 3D images to the treatment can be summarized as evaluating the parent artery relationship, revealing the number and shapes of aneurysm babies more clearly, detecting fenestrations, and shortening procedure time by finding the correct working angle.

RESUMO

BACKGROUND: We report our initial experience with the CatchView (CV) thrombectomy device in patients with acute ischemic stroke (AIS). METHODS: A retrospective analysis of 53 of 284 AIS patients (mean age 66.6±14.8 years, range 37-94) treated with a CV device between January 2019 and February 2020 was performed. The baseline characteristics (gender, age, comorbidities, National Institutes of Health Stroke Scale (NIHSS) score, intravenous tissue plasminogen activator (IV-tPA) administration, and occlusion localization) of these subjects were recorded. Modified Thrombolysis in Cerebral Ischemia (mTICI) scores of 2b and 3 were considered to indicate successful recanalization, and subjects with a modified Rankin Scale score of ≤2 on day 90 was considered a good clinical outcomes. RESULTS: The mean NIHSS score was 12.3±3. Successful recanalization was achieved in 45 subjects (84.90%), and the rate of good clinical outcomes on day 90 was 43.39%. The secondary distal embolus rate was 5.66%. Symptomatic hemorrhage was observed in 3.77% of the subjects, and the mortality rate was 13.2%. CONCLUSIONS: Mechanical thrombectomy devices include a wide array of endovascular tools for removing clots in AIS patients. In terms of successful recanalization and good clinical outcomes on day 90, our initial experience with the CV devices was encouraging.

RESUMO

AIM: To assess the safety and efficacy of distal thrombectomy (DT) using a Catch View mini (CVm) device via a microcatheter with a 0.013-inch inner diameter. MATERIAL AND METHODS: Nine of 246 acute ischemic stroke patients who underwent mechanical thrombectomy developed distal emboli and were included in the study. In all nine subjects (mean age, 64.5 ± 11.6; range, 39?77 years), a combination of CVm and a 0.013-inch microcatheter was used in distal mechanical thrombectomy. Modified Thrombolysis in Cerebral Ischemia scores of 2c and 3 were considered to indicate successful recanalization, and patients with a Modified Rankin Score of ? 2 on the 90th day were considered to have good clinical outcomes. RESULTS: Eleven DT maneuvers were performed using the same stent retriever and microcatheter. The mean National Institutes of Health Stroke Scale score was 13 ± 3.4. Thrombectomy was performed from M3 in six patients, A3 in four, and P3 in one. Successful recanalization was achieved in all of the procedures. The rate of good clinical outcome was 55.5%. CONCLUSION: Advances in technology in the endovascular field enable access to more distal vessels in acute ischemic stroke. As the profile of the instruments used during access decreases, the risk of complications may decrease. The CVm stent retriever could become a useful tool in DT based on its compatibility with a 0.013-inch lumen delivery system.

RESUMO

Background/aim: We aimed to investigate the role of Shearwave Elastography (SWE) in the evaluation of response to uterine artery embolization (UAE) in patients with uterine leiomyomas. Materials and methods: SWE images of the dominant uterin leiomyomas were obtained before and 1.5 months after performing UAE in 33 women suffering from symptoms due to leiomyomas (menometrorrhagia, bulk related symptoms, pelvic pain). Leiomyomas were also evaluated by 2 observers for location and longest diameter in axial plane. Interobserver agreement in the quantitative SWE analysis was calculated using intraclass correlation coefficients. Results: Thirty-three women (mean age, 39.7 years; range, 31­48 years) were examined with SWE 1.5 months after UAE. After treatment, 3 patients (9.1%) had fever, 1 patient had nausea and 29 patients (87.9%) had no complications. The post UAE stiffness measurements of leiomyomas (mean SWE ± SD = 13.34 ± 3.9kPa) were significantly lower than the pre UAE measurements (mean SWE ± SD = 17.16 ± 4.8kPa) (P < 0.001). There was excellent agreement between the 2 blinded observers in SWE measurements. Conclusion: SWE values of leiomyomas after UAE significantly decreased. SWE, with its high reproducibility, could become a useful tool in the follow up of uterin leiomyomas after UAE.

RESUMO

OBJECTIVES: Treating aortic arch aneurysms with conventional open surgical and endovascular stent graft procedures is challenging due to the complex anatomy of the arch and the arteries arising from it that nourish the brain. Cerebral protection is of the utmost importance during the treatment of thoracic aneurysms involving the aortic arch. METHODS: Between May 2014 and November 2018, 7 patients with thoracic aortic aneurysms involving the aortic arch who underwent aortic arch cervical debranching with our technique were reviewed retrospectively. Because all the patients being considered for conventional surgical aortic arch replacement had serious comorbidities, they were selected to receive hybrid therapy. The mean age of the patients was 71.2 ± 9.4 years. One patient was a woman and 6 patients were men. One patient was given general anaesthesia; the remaining 6 patients had a regional block. A crossover temporary bypass was performed between the external carotid arteries with a 6-mm polytetrafluoroethylene graft for cerebral protection in all patients. Thoracic endovascular aortic repair (TEVAR) was successfully performed in all patients except 1 following debranching. RESULTS: Neurological complications did not occur during the procedures. Patients were followed for a mean of 18.3 ± 4.9 months. One female patient died of exacerbating chronic obstructive pulmonary disease within the first follow-up year. Three other patients died: 1 died of natural causes; 1 died of pneumonia followed by multiorgan failure; and 1 died of myocardial infarction during the mid-term follow-up period. The remaining patients are still being followed and are event free. CONCLUSIONS: Endovascular treatment of thoracic aortic diseases involving the aortic arch is facilitated when the aortic arch is debranched. Our cerebral protection method with a temporary crossover bypass between the external carotid arteries provides continuous pulsatile blood flow to the brain; hence, neurologically, it is a reliable procedure. The follow-up results of the patients who underwent aortic arch cervical debranching followed by TEVAR depended on their comorbidities.

RESUMO

BACKGROUND: Esophageal motility studies are performed in patients who have dysphagia that is not explained by stenosis. Diagnosis can be challenging and requires expertise in the interpretation of tests and symptoms. AIMS: Our aim is to investigate the diagnostic value of videofluoroscopic swallowing study (VFSS) in combination with esophageal manometry. STUDY DESIGN: This study has a prospective study design. METHODS: 73 patients with dysphagia underwent videofluoroscopy in a standing position. Each subject swallowed barium boluses and findings were correlated with manometry findings. RESULTS: The study cohort was categorized into five groups according to their disease as achalasia (31.1%), presbyesophagus (4.1%), scleroderma (5.5%), neurogenic dysphagia (6.8%), and other diseases (54.4%), which included gastroesophageal reflux, diffuse esophageal spasm, cricopharyngeal achalasia, and diseases with nonspecific VFSS patterns. When evaluating VFSS, the perfect agreement was observed between two observers in the final diagnosis. (kappa: 0.91, p<0,001). CONCLUSION: Although it does not replace manometry, VFSS is important as an additional useful imaging method in EMDs.

RESUMO

BACKGROUND: Hemodynamic depression (HD) is a condition that can be encountered after carotid stenting (CAS) and carotid angioplasty (CAP) due to manipulation of the carotid sinus. The aim of this study was to evaluate whether the carotid bifurcation geometry and angles, or changes in angles, were associated with this HD in patients undergoing CAS and CAP. METHODS: Sixty-two patients with a mean age of 71.1±7.4 years, who underwent CAS and CAP for carotid stenosis were included in the study. HD was defined as periprocedural hypotension (systolic blood pressure <90 mmHg) or bradycardia (heart rate <60 bpm). The effect of carotid bifurcation geometry, plaque morphology and risk factors on subsequent development of HD was analyzed with binary logistic regression models. ICA-CCA angle was measured from digital subtraction angiographies (DSA) before and after stent deployment by two radiologists. Interobserver agreement was calculated. RESULTS: Periprocedural HD was seen in 22 (35.5%) patients. Extension of carotid lesion to bulbus, preoperative internal carotid artery (ICA) angle, postoperative angular changes, pre-op systolic blood pressure, balloon-to-artery ratio and HD were significantly correlated. A significant difference was observed between the angle of ICA before and after the procedure between the patients with HD and those without HD. CONCLUSIONS: Carotid anatomy and geometry may enhance the risk of HD independent of other factors and may be of help in very early identification of patients at high risk of developing HD after CAS and CAP.
