Preventing the Catastrophe: Aberrant Carotid in Adenoid and Tonsil Surgery: Two Case Reports

Background: Adenoid and tonsil surgeries are the most commonly done surgical procedures, with haemorrhage being an important complication. Fatalities due to haemorrhage almost never occur, but the occasional devastating outcomes that are life-threatening become a frequent source of litigations and audits. Catastrophic bleeds are usually due to an aberrant vessel or carotid protruding in the pharyngeal airway. The aberrant carotid poses a risk during routine pharyngeal surgeries like adenoidectomy, tonsillectomy, Quincy and Para-pharyngeal abscess drainage, UPPP, pharyngeal biopsies, etc. and injuries during routine pharyngeal surgical procedures can be catastrophic due to massive bleeding. Case report: We report two cases of routine Adeno-tonsillectomy surgeries where aberrant carotid vessels protruding in the adeno-tonsil surgical area were identified by endoscopic transoral evaluation intraoperatively. The surgery in these cases was postponed for further investigation due to the risk of injury and catastrophic bleeding. Conclusion: Aberrant carotids are usually clinically silent, and adenoid removal in most cases is a blind procedure done by curettage. There are no guidelines to identify aberrant vessels pre or intraoperatively, and preventing injury and catastrophic bleeding depends on surgeon’s experience and caution. These cases underline the importance of due vigilance and taking steps before starting the procedures, particularly pre-and intraoperative transoral endoscopic assessment for identifying aberrant vessels in the upper airway area, thus preventing injury and avoiding devastating complications. We report these cases and underline the steps to identify aberrant vessels in the upper airway surgical field before starting surgery to prevent a potentially catastrophic complication.

Ileocaecal Tuberculosis Presenting with Massive Hematochezia: A Rare Clinical Manifestation

Abdominal pain, diarrhea, weight loss, anorexia, and fever are common symptoms of intestinal tuberculosis, while bleeding from the lumen, intestinal obstruction, perforation, and fistula formation are uncommon presentations in ileocaecal tuberculosis. Here, we present a case of a 33-year-old male with intestinal tuberculosis who initially presented with massive bleeding per rectum.

Safety of Uncrossmatched ABO-Compatible RBCs in Alloimmunized Patients with Bleeding: Data from Two Decades: Results of a Systematic Analysis in 6,109 Patients

<b><i>Introduction:</i></b> Uncrossmatched ABO-compatible red blood cells (RBCs) are generally recommended in patients with life-threatening massive bleeding. There is little data regarding RBC transfusion when patients are transfused against clinically significant alloantibodies because compatible RBCs are not immediately available. <b><i>Methods/Patients:</i></b> All patients reviewed in this study (<i>n</i> = 6,109) required emergency blood transfusion and were treated at the Charité – Universitätsmedizin Berlin between 2001 and 2015. Primary uncrossmatched O Rh(D)-positive or -negative RBC units were immediately transfused prior to complete regulatory serological testing including determination of ABO group, Rhesus antigens, antibody screening, and crossmatching. <b><i>Results:</i></b> Without any significant change in the protocol of emergency transfusion of RBCs, a total of 63,373 RBC units were transfused in 6,109 patients. Antibody screening was positive in 413 patients (6.8%), and 19 of these patients received RBC units against clinically significant alloantibodies. None of these patients appeared to have developed significant hemolysis, and only one patient with anti-D seems to have developed signs of insignificant hemolysis following the transfusion of three Rh(D)-positive units. One patient who had anti-Jk^a received unselected units and did not develop a hemolytic transfusion reaction. <b><i>Conclusion:</i></b> Transfusion of uncrossmatched ABO-compatible RBCs against alloantibodies is highly safe in patients with life-threatening hemorrhage.

Tracheoarterial fistula as a complication of prolonged tracheostomy

The article presents a clinical case of a rare and severe complication of prolonged tracheostomy in the form of fistula formation between tracheal lumen and brachiocephalic artery and the development of massive bleeding from it. The patient’s treatment was urgent and successful. Operative intervention was performed with subsequent allografting of brachiocephalic trunk (vascular prosthesis Vascutek 8 mm was used) and the anastomosis was created using a continuous suture technique. The patient was discharged home in a satisfactory condition on the 17th post-operative day.

Meckel’s diverticulum with intraperitoneal hemorrhage in a child detected with screening laparoscopy: a case report

Background The most common presentation of symptomatic Meckel’s diverticulum (MD) are intestinal obstruction, gastrointestinal hemorrhage, and inflammation of the MD with or without perforation. Intraperitoneal hemorrhage because of MD is extremely rare. We report a case of MD with intraperitoneal hemorrhage in a child detected with screening laparoscopy. Case presentation An 11-year-old girl presented to another hospital with lower abdominal pain and vomiting that lasted for 2 days. Acute appendicitis was suspected, and she was referred to our department. Abdominal enhanced computed tomography showed an abscess in the lower abdomen with ascites in the pelvis. She was diagnosed with a localized intra-abdominal abscess and the decision was made to treat with antibiotics. However, her abdominal pain worsened, with abdominal distension, tenderness and guarding. She was diagnosed with panperitonitis and the decision was made for surgery 5 h after admission. During surgery, laparoscopic observation from the umbilical region revealed 200 ml of fresh blood throughout the peritoneal cavity, originating from the mesentery of the ileum. MD was observed with bleeding from the surrounding mesentery. Small bowel resection was performed, and the patient was discharged on the 5th postoperative day. Pathological findings revealed an MD containing ectopic gastric mucosa and small intestinal ulcer perforation at the base of the MD. Conclusions We report an extremely rare case of an MD with intraperitoneal hemorrhage in a child. In pediatric cases, it is possible that perforation with ectopic gastric mucosa may cause massive bleeding because of rupture of the surrounding mesenteric blood vessels.

Intravenous infusion route in maternal resuscitation: a scoping review

Background The concept that upper extremities can be used as an infusion route during cardiopulmonary resuscitation in pregnant women is a reasonable recommendation considering the characteristic circulation of pregnant women; however, this method is not based on scientific evidence. Objective of the review We conducted a scoping review to determine whether the infusion route should be established above the diaphragm during cardiopulmonary resuscitation in a pregnant woman. Discussion We included randomized controlled trials (RCTs) and non-RCTs on the infusion of fluids in pregnant women after 20 weeks of gestation requiring establishment of an infusion route due to cardiac arrest, massive bleeding, intra-abdominal bleeding, cesarean section, severe infection, or thrombosis. In total, 3150 articles from electronic database were extracted, respectively. After title and abstract review, 265 articles were extracted, and 116 articles were extracted by full-text screening, which were included in the final analysis. The 116 articles included 78 studies on infusion for pregnant women. The location of the intravenous infusion route could be confirmed in only 17 studies, all of which used the upper extremity to secure the venous route. Conclusion Pregnant women undergo significant physiological changes that differ from those of normal adults, because of pressure and drainage of the inferior vena cava and pelvic veins by the enlarged uterus. Therefore, despite a lack of evidence, it seems logical to secure the infusion route above the diaphragm when resuscitating a pregnant woman.
