 PERSISTENCE OF THE LEFT SUPERIOR VENA CAVA AS AN ANATOMICAL VARIANT by Tacuri J in Journal of Clinical Case Reports Medical Images and Health Sciences

A 74-year-old male patient, diabetic, hypertensive, with severe heart disease, with chronic kidney disease in three-week dialysis treatment, a tunneled catheter for hemodialysis is placed in the left internal jugular vein, however, when performing his control in the chest X-ray (Image A), it is observed that the catheter takes a direction towards the left side of the heart, the patient was asymptomatic and with normal vital signs; An angiotomography was requested (Image B, C) in which the presence of an anatomical variant consisting of the persistence of the Left Superior Vena Cava, type IIIa in which there is the presence of the two superior vena cavas with connection of the persistent left superior vena cava with the right superior vena cava. This anatomical variant is due to the failure to obliterate the left anterior cardinal vein, which results in the persistence of the left superior vena cava (LSVC). This abnormal vein derives from the left anterior cardinal vein and the common cardinal veins. The coronary sinus is dilated and serves as the conduit between the LSVC and the right atrium, and the frequency is about 0.3% to 0.5% a world level (1). The patient is currently receiving hemodialysis sessions through said catheter without inconvenience, it is worth mentioning that the patient is not eligible for the creation of an arteriovenous fistula.

Case Report about an Open Enucleation of the Talus by Drs. Bensaka Mohammed in Journal of Clinical Case Reports Medical Images and Health Sciences

 Case Report about an Open Enucleation of the Talus by Drs. Bensaka Mohammed in Journal of Clinical Case Reports Medical Images and Health Sciences Abstract  We report a case of open enucleation of the talus, surgically treated conservatively. Enucleation or triple dislocation of the talus is a rare and serious traumatic injury. The study reports case of a 55 years old, was the victim of an attack by a stone with a direct point of impact on the right ankle while the foot was fixed, resulting in total functional impotence and severe pain. Enucleation of the talus is a rare lesion, rarely described in the literature. The functional prognosis of the ankle is compromised by the risk of osteonecrosis. Introduction  Talus Enucleation or triple dislocation of the talus is a rare traumatic injury [1,2] accounting for 2- 10% of talar traumas [3,4]. A review of the literature revealed fewer than 80 cases of pure enucleation of the talus [5], and the majority were a consequence of...

Fish bone: unusual cause of liver abscess by Haithem Zaafouri in Journal of Clinical Case Reports Medical Images and Health Sciences

  Fish bone: unusual cause of liver abscess by Haithem Zaafouri in Journal of Clinical Case Reports Medical Images and Health Sciences Description  A 41-year-old female admitted to our department of general surgery with a three days history of abdominal pain, fever and shivering. She was previously healthy without any past medical history. On examination, she was febrile at 39°C, and she had tenderness in the epigastric quadrant of the abdomen. Biological data showed leukocytosis at 22.10³ E/L, high C - reactive protein at 300mg/L, normal amylase and liver enzymesThe abdominal CT scan revealed a 5 cm left hepatic lobe abscess with hyperdense image into parenchyma which matches a 2 cm linear structure with calcium density. After ten days of intravenous antibiotics, an exploratory laparoscopy was done, and the foreign body was extracted etiopathogenic mechanism explains the left site of the hepatic abscess in these conditions. The extraction of the foreign body which can b...

Local anaesthesia as a standard of care for penetrating keratoplasty? by Dr. Ahmed Alwan Shalal in Journal of Clinical Case Reports Medical Images and Health Sciences

  Local anaesthesia as a standard of care for penetrating keratoplasty? by Dr. Ahmed Alwan Shalal in Journal of Clinical Case Reports Medical Images and Health Sciences Abstract  The purpose of this study was to ascertain the safety and preferences of local anesthetic (LA) for penetrating keratoplasty. A review of all PKs completed at Ibn Al-Ahaitham Teaching Eye Hospital over the previous four years (2018– 2021) in order to determine the incidence of serious complications. To ascertain patterns in PK's anesthetic use, structured interviews with hospitalized cornea experts were conducted. Continuous data were expressed as mean (SD), whilst categorical variables were expressed as a number (%). In local anesthesia, 41% of the population was under 30, while 59% was over 30. Of these, 69.1% were female. In general anesthesia, there were 56.9% more women than men, 43.1% more men than women, and 33.3% more people under 30 than over 30. Expulsive suprachoroidal hemorrhage (SCH) and...
