RESUMO
Introduction: Surgical correction is the fundamental strategyfor severe rheumatic mitral regurgitation as (MR) as medicalmanagement for MR can not prevent the hemodynamicconsequences of severe MR in the asymptomatic andminimally symptomatic subjects. The purpose of this study isto assess the impact of duration of progressive rheumatic MRon LVEF, PH, LV and right ventricular dysfunction and decideabout the selection of optimal timing for surgical interventionin our patient population.Material and methods: This study involves the data of 30patients of MVR divided over 2 groups, from 1st January 2015to 31st December, 2018 and follow up of the survivors. Therewere (a) 12 cases of isolated severe MR described as MR and(b) 18 cases of severe MR associated with mild MS describedas MS +MR. Changes in echocardiographic parameters inboth the groups after MVR, LVEF, LVESD, LV end diastolicdiameter (LVEDD), PASP and NYHA functional class wereassessed, analyzed and compared at 30 and 180 days.Results: In the postoperative period after 30 days,improvement of NYHA status were observed to be higher in13 survivors with MS +MR from III to I while it was 6 in MRgroup. This improvement noted more in younger group below40 years. NYHA changes from III to II was observed in 4 ineach in both groups more in older group above 40 years. At180 days, 1 each from NYHA II improved to I in youngergroup. Out of the 2 post operative mortality, there was 1 in MRgroup who had post operative RV dysfunction and died afterdischarge on 29th day and 1 in MS+MR group and who diedof respiratory failure after 7 days though the cardiac indicesimproved and both were in older group.Conclusion: MVR can reversely remodel hearts and restoreLV function with relatively preserved LV.
RESUMO
Introduction: Urethral stricture is a common condition with varying etiology and management, determined by cause, site and length of stricture. Materials and methods: We presented here a randomized prospective trial comparing dorsal onlay buccal mucosa graft and penile skin flap urethroplasty at our institute over 3 years period. Results: Total 22 patients underwent substitution urethroplasty during this period. The mean age and follow up was 31.31 years and 9 months respectively. The most common cause of stricture urethra was post inflammatory (40.90%) followed by traumatic (36.36%) and balanitis xerotica obliterence (22.72%). Majority had combined penobulbar stricture (45.45%), followed by penile (31.81%) and bulbar (22.7%). The average size of the urethral stricture was 6.81 cm. The most common symptom of presentation of stricture urethra was thin stream (100%) followed by dysuria (80%), frequency (71.42%) and dribbling (30%). Most of the patients underwent surgical procedure prior to presentation; urethral dilatation done in 13 (59.05%) patients followed by visual internal urethrotomy 7 (31.81%) patients and suprapubic cystostomy in 4 (18.18%) patients. Of 22 patients, 10 (45.45%) underwent local flap and 12 (54.54%) patients buccal mucosal graft. Out of 10 local flap technique, 8 (36.36%) patients underwent ventral longitudinal flap and 2 (9.09%) underwent Quartey flap. Out of 12 buccal mucosal graft technique, 5 (22.72%) patients underwent ventral onlay graft, 5 (22.72%) dorsal onlay and 2 (9.09%) tube circumferential graft. Total success rate was 72.72%. Success rate was higher with buccal mucosal graft (83.33%) compared to local flap technique (60%). Among local G. Mallikarjuna, N. Ramamurthy, G. Ravichander, Ravi Jahagirdar, Jagadeeshwar. Substitution urethroplasty: Buccal mucosal graft Vs local flaps - A prospective randomized study. IAIM, 2016; 3(10): 162-173. Page 163 flap technique, ventral longitudinal flap (62.5%) had better results than quartey flap (50%). Among buccal mucosal graft dorsal onlay graft had best (100%) results followed by ventral onlay (80%) and then tube circumferencial graft (50%). Patients with smaller stricture length (2.5-7.5 cm) had better (75%) results. Patients with combined penobulbar (90%) and BXO as etiology (80%) also had better results. Conclusion: The success rate of buccal mucosal free graft substitution urethroplasty is better than local penile skin flaps in patients with anterior urethral strictures.
