However, previous case reports regarding the management of laparoscopic surgery in adult patients with congenital heart disease are limited. A 72-year-old man who underwent a laparoscopic right colectomy for colon cancer had a residual ventricular septal defect and right ventricular outflow tract obstruction despite post-repair of tetralogy of Fallot. Pulmonary hypertension or right ventricular dysfunction was not observed. The preoperative pulmonary to systemic blood flow ratio (Qp/Qs) was 2.3. After positive pressure ventilation and insufflation, the amount of left-to-right ventricular shunting decreased, and the Qp/Qs approached 1.0, as calculated from pulmonary arterial and systemic arterial blood gas analysis. Laparoscopic surgery might be tolerable in patients with tetralogy of Fallot who have preserved the right ventricular function, left-to-right ventricular shunting, and no high pulmonary vascular resistance.","PeriodicalId":14635,"journal":{"name":"JA Clinical Reports","volume":"20 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140576091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initial MEP monitoring after prone positioning revealed markedly prolonged latency and lower amplitude in the left abductor pollicis brevis (APB). Because the left upper limb somatosensory-evoked potentials had normal values, a position-related impending peripheral nerve injury located between the neck and the forearm was excluded. Postoperative examination revealed that MEP abnormality in the left APB was caused by carpal tunnel syndrome. Abnormal initial MEP from the upper limb was unexpectedly detected after prone positioning during lumbar spine surgery.

Low pump flow in patients on extracorporeal life support (ECLS) with LV apex decompression is a life-threatening issue. However, identifying the underlying causes of low flow can be challenging. A 38-year-old woman with COVID-19-related fulminant myocarditis was treated with central ECLS with LV apex decompression. The pump flow in the intensive care unit (ICU) was intermittently low, and low flow alerts were frequent. The initial evaluation based on pressure monitor waveforms and transthoracic echocardiography failed to identify the underlying cause. Prompt bedside transesophageal echocardiography (TEE) revealed that the anterolateral papillary muscle was suctioned into the vent cannula of the LV apex during systole. The patient underwent a repeat sternal midline incision in the operating room, and the cannula at the LV apex was repositioned. There were no further suction events after the repositioning, and the patient was weaned from ECLS 12 days after admission to the ICU. The patient was discharged in a stable condition and without neurological deficits. TEE is an important diagnostic tool to identify the underlying cause of low flow flow in patients undergoing ECLS with LV apex decompression.","PeriodicalId":14635,"journal":{"name":"JA Clinical Reports","volume":"71 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140576090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ultrasound-guided catheter insertion is commonly performed using an in-plane or out-of-plane approach [1]. However, it is unclear which approach is more effective. Herein, we report a case in which a catheter for continuous rectus sheath block unexpectedly reached the abdominal cavity, via an out-of-plane approach.</p><p>A 67-year-old woman underwent bilateral rectus sheath blocks with a catheter-through-needle technique (Hakko Disposable Pain Clinic Set®, Hakko, Japan) after open surgical repair of abdominal aortic aneurysm. On ultrasound, due to the surgical wound, the posterior sheath of the rectus abdominis muscle could not be visualized well in the long-axis view with a linear probe; thus, we placed two catheters (left and right sides) under the short-axis view of the rectus sheath muscle using an out-of-plane approach, while injecting a small amount of drug solution to confirm the tips of needle. When we advanced the needle to the proper location, we observed the spread of local anesthetic (0.25% levobupivacaine, 20 mL per one side) along the rectal sheath. Then, we inserted the catheter, rigidly holding the needle in place so it would not shift from its position. However, the tip of the catheter was not clearly visible on ultrasound, and we did not evaluate the spread of local anesthetics administered through the catheter. On the Postoperative Day 1, routine postoperative computed tomography revealed that the right catheter had strayed into the abdominal cavity (Fig. 1).
