ABSTRACT
@#Objective To explore the safety and effectiveness of a precise marking method based on body surface mesh and three-dimensional (3D) image reconstruction. Methods We retrospectively analyzed the clinical data of 22 patients in our hospital from October 2018 to October 2019. There were 13 males and 9 females aged 58.5 (37-72) years. All patients underwent a precise marking of pulmonary nodules based on body surface mesh and 3D image reconstruction. Then, video-assisted thoracoscopic surgery (VATS) was performed to resect the nodules. The clinical data, including positioning success rate and operation time were analyzed. Results A total of 22 small pulmonary nodules were removed. The average diameter of small nodules was 12±3 mm, and the average distance from the visceral pleura was 17±6 mm. The localization success rate was 86.4%. The operation time was 110±43 min, and there was no surgery-related complication. Conclusion The method of marking pulmonary nodules based on body surface mesh and 3D image reconstruction is a safe and reliable technology, which reduces the risk of hemopneumothorax caused by CT-guided lung puncture.
ABSTRACT
Background and objectives: Moderator band is a specialized bridge present between the base of the anteriorpapillary muscle and interventricular septum. It carries the right branch of the bundle of HIS with it. The band isknown to prevent the over distension of the right ventricle during the diastolic phase. There is a need of lot ofresearch and studies on the septomarginal trabecula as it proves to be important clinically. Here we measuredthe length, breadth, height, angle with the interventricular septum, and the superficial marking of Moderatorband on the sternocostal surface of the right ventricle is done. This paper describes the morphological variationsfound in its origin and insertion.Materials and Methods: 15 formalin-soaked cadaveric hearts were taken from the Department of Anatomy ofKVG Medical College, Sullia. The foetal hearts, the hearts with gross pathology, if any are excluded from the study.Result: The morphometric parameters are tabulated and the morphological variations are noted. The results arecompared with the results of the previous studies on the moderator band.Conclusion: It is confirmed that the thickness of moderator band varies at its origin and insertion. The surfacemarking of moderator band on sternocostal surface of the heart will help in locating the moderator band throughthe echocardiography and during cardiac surgeries on right ventricle. The possibility of second moderator band,multiple origin or insertion is more than 20%.
ABSTRACT
Background: Exact surface localization of foreign body is vital prior to its surgical removal. Preoperative localization errors lead to excessive soft tissue exploration, prolonged surgery, increased morbidity and post-surgical complications. Sarkar KN, Mandal SK, Kabiraj P, Mallik R, Gupta DK, Sarkar M. Consistency and percentage agreement of preoperative surface marking of subcutaneous foreign body by colour comet tail artefact with its intra-operative positional findings - A prospective study. IAIM, 2016; 3(6): 32-41. Page 33 Aim: Determination of percentage agreement of preoperative surface marking of subcutaneous foreign body by colour comet tail artefact with its intra-operative positional findings. Materials and methods: Prospective observational study was conducted on 100 patients over duration of eight months from September 2015 to April 2016 at our institution. Preoperative surface marking of foreign body was done using Ultrasound machine PHILIPS HD7 (2.0.1) with 7 MHz linear transducer, Excel mark premium black stamp ink 2oz, Acco smooth steel wire paper clip, Trade mark 45 cm wooden measuring scale and Apsara glass marking pencil. Percentage agreement of preoperative surface marking of subcutaneous foreign body by colour comet tail artefact with its intraoperative positional findings was studied in 100 patients prospectively. All analysis was done by using IBM SSPS statistics 24 and MS Excel. Results: The color tail artifact technique showed percentage agreement of 93.5% for accurate surface marking of vertical line within ≤ 5 mm of actual location and percentage agreement of 92.5% for surface marking of horizontal line within ≤ 5 mm of actual location. Conclusions: Blind surgical procedures of foreign body removal have been replaced by real time ultrasound guided removal under strict sterile conditions in most of the affluent nations. However in developing nations and semi urban places where there is limited and underrated sterilization and disinfection technique, real time ultrasound procedures for foreign body removal remains a challenging option. This study shall suffice to the needs of developing nations and semi urban places with precise preoperative surface localization, advantages of minimal surgical exploration, minimal local tissue injury, reduced patient’s morbidity and no real time ultrasound associated nosocomial infection. The study shall also be helpful with special emphasis to those underserved villages where surgeons still rely on blind foreign body removal procedures, causing massive tissue exploration, increased hospital stay, increased cost of treatment, failure of removal and increased patients morbidity.
ABSTRACT
In order to improve the efficacy of vibration expectoration and prevent secondary injury in patients with chest trauma,the body surface marking method was used in vibration expectoration.The exact injured locations and areas were identified via CT ot X-ray results.Then,the restricted and focused areas of expectoration were marked with red and green colors,which could guide the machines to avoid the fracture sites,reduce pain,prevent secondary injury and administrate effective expectoration in the areas of sputum and atelectasis.However,the dynamic CT or X-ray results must be used for reference to ensure the accuracy of the body surface marking.
