Anaesthetic management for hip arthroplasty in a 46-yr-old patient with uncorrected truncus arteriosus type IV

Anesthetic management of a pregnant patient with Eisenmenger's syndrome: A case report

BACKGROUND

Eisenmenger's syndrome (ES) is a rare complication of congenital heart disease that includes pulmonary artery hypertension and reversed or bidirectional shunts. The mortality rate of pregnant women with ES is 30%-70% due to pathophysiological deterioration. Successful perioperative management of a pregnant patient with ES is a challenge for anesthesiologists.

CASE SUMMARY

A 38-year-old pregnant woman was admitted to the cardiology department of our hospital at 22 wk of gestation with complaints of chest tightness and shortness of breath for 3 wk. Transthoracic echocardiography revealed a bidirectional shunt between the descending aorta and pulmonary artery after interventional closure of the patent ductus arteriosus and severe pulmonary hypertension. ES in pregnancy was our primary suspicion. The patient elected to terminate the pregnancy under adequate preoperative preparation, rigorous intraoperative monitoring, and perfect epidural anesthesia. She was discharged successfully on postoperative day 16.

CONCLUSION

Our experience in this case suggests that successful outcomes are possible in pregnant patients with ES for termination of pregnancy under epidural anesthesia and intensive monitoring.

Laparoscopic radical resection for rectal cancer in a patient with uncorrected truncus arteriosus type IV: A case report

Persistent truncus arteriosus is a rare congenital heart malformation which if not corrected, results in the death of about 50% of the patients, while fewer than 20% of the patients survive the first year of life. Here, we report the successful anesthetic management of an adult patient with uncorrected truncus arteriosus who presented for the laparoscopic radical resection of rectal cancer.

Perioperative and Anesthetic Considerations in Truncus Arteriosus

Truncus arteriosus is a congenital cardiac lesion in which failure of embryonic truncal septation results in a single semilunar valve and single arterial trunk providing both pulmonary and systemic circulations. Most patients with this lesion are symptomatic in the neonatal period with cyanosis and/or congestive heart failure and undergo complete repair in the first weeks of life. This review will focus on the anatomy, physiology, and perioperative anesthetic management of patients with truncus arteriosus.

Case Report. Persistent Common Arterial Trunk in an Adult Presenting in the Emergency Room as Severely Decompensated Heart Failure

Truncus arteriosus (TA) or common arterial trunk is a rare malformation, accounting for 0.21 to 0.34% of congenital heart diseases, which, if left untreated, leads to increased mortality rates. The condition is characterized by the presence of a unique arterial trunk that overrides the interventricular septum. Despite an overall poor outcome, few subjects present in emergency settings with signs suggestive for pulmonary arterial hypoplasia and associated heart failure. We report the case of a 31-year-old female patient who had been previously diagnosed with pulmonary atresia and severe scoliosis as an infant, presenting in the emergency department with clinical sings of decompensated heart failure which were demonstrated to be attributable to the severe cyanogenic heart malformation and were reversible after initiation of appropriate therapeutic measures.

Eisenmenger's syndrome in pregnancy: use of Proseal laryngeal mask airway (PLMA) and epidural analgesia for elective cesarean section

We describe the successful anesthetic management of cesarean section in a patient with Eisenmenger's syndrome secondary to an atrial septal defect. Although conception is discouraged in women with Eisenmenger's syndrome, in inevitable circumstances, careful and meticulous planning of anesthesia can help the parturient survive the ordeal of a cesarean section. The cardiac output must be maintained and systemic vascular resistance must not be allowed to fall. This should ensure that there is minimal change in the right to left shunt. In our patient, the scenario of Eisenmenger's syndrome was complicated by biventricular hypertrophy. We achieved the goals in our patient by using general anesthesia with the Proseal laryngeal mask airway, a combination of ketamine and propofol, and epidural analgesia.
