RESUMEN

BACKGROUND: There are various other collaterals draining into the venous system around the saphenofemoral junction in addition to the great saphenous vein. We aimed to determine the efficiency of prophylactic ablation of tributary veins in long term varicose vein and symptom recurrence. METHODS: Two hundred and sixty-three consecutive patients whom underwent radiofrequency ablation therapy for the treatment of superficial venous reflux disease were investigated. There were 129 patients who received isolated great saphenous vein ablation (Group A) where as 134 patients underwent ablation of the other tributary veins in addition to the great saphenous vein (Group B) between June 2015 and January 2017. The tributary superficial veins; refluxing and/or not refluxing, draining into the saphenofemoral junction were selectively catheterized and ablated in Group B. Patients are followed at least 1 year after the procedures regulary and researched for recurrence of varciose veins and symptoms. RESULTS: Gender, mean age, body mass index, diameter of the great saphenous veins, small saphenous vein disease, and grade of deep venous insufficiency did not differ significantly between the two groups. The mean number of tributary veins were similar in both groups (n: 1.9 ± 0.4 in Group A vs. n: 1.8 ± 0.7 in Group B) which were detected preoperatively as well as during the procedure. The mean number of ablated tributary venous pathways could be 1.4 ± 0.6 in Group B. During the follow up period symptoms related with varicose veins recurred in 19 patients in Group A where as in 7 patients in Group B (P < 0.05). Three of these symptomatic patients in Group B were the ones in whom the tributary pathways could not be catheterized ablated where as 14 patients in Group A were diagnosed with newly refluxing tributary pathways. All the symptomatic patients in both groups were managed medically and/or with additional interventions. CONCLUSION: The absence of any fascial unsheathing and the parietal weakness are suggestive of a lower resistance of the tributary veins wall, so collapse and size of veins make it more complex to catheterization regarding to great saphenous vein. Ablation of the tributary superficial venous pathways during the treatment of great saphenous vein reflux disease decreased the rate of recurrence of superficial venous reflux disease and patients symtoms in our modest cohort.

RESUMEN

Aneurysms and occlusive pathologies of the aorta are frequently associated with atherosclerosis; however, thoracoabdominal aortic aneurysm accompanied by Leriche syndrome is an extremely rare condition with challenging treatment strategy and without established surgical treatment protocols. In this report, we present our treatment strategy in a 64-year-old male patient with ischemic heart disease and type 5 thoracoabdominal aortic aneurysm accompanied by Leriche syndrome.

RESUMEN

INTRODUCTION: In this report, we aim to present our algorithm and results of patients with congenital cardiac disorders who underwent surgical or interventional procedures during the peak phase of the pandemics in our country. PATIENTS AND METHODS: The first COVID-19 case was diagnosed in Turkey on 11 March, 2020, and the peak phase seemed to end by the end of April. All the patients whom were referred, treated, or previously operated but still at the hospital during the peak phase of COVID-19 pandemics in the country were included into this retrospective study. Patient's diagnosis, interventions, adverse events, and early post-procedural courses were studied. RESULTS: Thirty-one patients with various diagnoses of congenital cardiovascular disorders were retrospectively reviewed. Ages of the patients ranged between 2 days and 16 years. Seventeen cases were males and 14 cases were females. Elective cases were postponed. Priority was given to interventional procedures, and five cases were treated percutaneously. Palliative procedures were preferred in patients whom presumably would require long hospital stay. Corrective procedures were not hesitated in prioritised stable patients. Mortality occurred in one patient. Eight patients out of 151 ICU admissions were diagnosed with COVID-19, and they were transferred to COVID-19 ICU immediately. Three nurses whom also took care of the paediatric cases became infected with SARS-CoV-2; however, the children did not catch the disease. CONCLUSION: Mandatory and emergent congenital cardiac percutaneous and surgical procedures may be performed with similar postoperative risks as there are no pandemics with meticulous care and preventive measures.

RESUMEN

Atrial fibrillation (AF) is diagnosed with the electrocardiogram, which is the gold standard in clinics. However, sufficient arrhythmia monitoring takes a long time, and many of the tests are made in only a few seconds, which can lead arrhythmia to be missed. Here, we propose a combined method to detect the effects of AF on atrial tissue. We characterize tissues obtained from patients with or without AF by scanning acoustic microscopy (SAM) and by Raman spectroscopy (RS) to construct a mechano-chemical profile. We classify the Raman spectral measurements of the tissue samples with an unsupervised clustering method, k-means and compare their chemical properties. Besides, we utilize scanning acoustic microscopy to compare and determine differences in acoustic impedance maps of the groups. We compared the clinical outcomes with our findings using a neural network classification for Raman measurements and ANOVA for SAM measurements. Consequently, we show that the stiffness profiles of the tissues, corresponding to the patients with chronic AF, without AF or who experienced postoperative AF, are in agreement with the lipid-collagen profiles obtained by the Raman spectral characterization.

RESUMEN

OBJECTIVE: This study is planned bringing about a new choice for the prophylaxis of RA spasm which is topical iloprost and compares its efficacy with papaverine and diltiazem. DESIGN: Twenty eight CABG patients with RA grafts were categorized into four groups by taking into account the topical vasodilator (papaverine, diltiazem, iloprost and saline) that was utilized during harvesting. Arterial segments were separated into four rings and were than soaked with KCL, norepinephrine, phenylephrine and serotonin. Then, acetylcholine was given to induce relaxation and the preparations were put to rest for 10 minute. RESULTS: The contraction response achieved by the vasoreactive agents was most effectively inhibited by papaverine. The effectiveness of the response obtained by iloprost was similar to that of papaverine and significantly stronger than that of diltiazem. Especially at high vasoreactive substance concentrations, diltiazem had a contraction close to that of the control while the protective effect was weaker than those of papaverine and iloprost. CONCLUSION: Iloprost can be recommended as a strong alternative to the topical agents used for preventing arterial graft spasm.
