Postpartum Acute Aortic Dissection in a Patient Without a Connective Tissue Disorder: A Case Report.
Type A acute aortic dissection is a rare life-threatening event that occurs most commonly in the third trimester or early postpartum and in women with connective tissue disorders. However, this case describes a type A aortic dissection diagnosed on postpartum day 2 in a woman with preeclampsia without a history of a connective tissue disease. The case emphasizes the importance of considering dissection in any parturient complaining of chest pain, especially in the setting of hypertension and a new murmur. Emergent imaging must be considered to decrease delays in surgical repair and to minimize maternal morbidity and mortality.

We present the case of a 65-year-old man undergoing open-heart surgery through a full sternotomy with the use of bilateral intercostal cryo nerve block (cryoNB) as adjunctive therapy for postoperative analgesia. CryoNB has been previously demonstrated as safe and effective for pain control in thoracotomy procedures as well as bilaterally in adolescent patients with pectus excavatum undergoing Nuss procedure. Herein, we describe for the first time, the cryoNB procedure for postoperative pain management in a patient undergoing full sternotomy.

Case Reports
Endovascular Plug for Endobronchial Management of an Expectorated Pulmonary Artery Embolization Coil: A Case Report.
Pulmonary artery aneurysms are frequently managed with endovascular embolization. Rare but serious complications of coil embolization are erosion and migration of the coils into the adjacent airways, posing a risk for massive hemoptysis. We report the case of a medically complex patient with a left main pulmonary artery aneurysm treated with coil embolization who ultimately experienced transbronchial migration and expectoration of the coil. We discuss the challenging anesthetic and surgical management of these serious complications, including the use of an endovascular plug to occlude the erosion site and distal airways.

Case Reports
Left Stellate Ganglion Blockade for Refractory Ventricular Arrhythmias With Aconitine Poisoning: A Case Report.
Aconitine poisoning causes refractory ventricular arrhythmias (VAs). In a 20-year-old man, VAs of unknown etiology did not respond to drugs and electrical defibrillation. ⋯ Left SGB is effective for treating refractory VAs with aconitine poisoning and can be easily performed with few complications for VAs of unknown etiology even if patients are receiving anticoagulant therapy. Also, left SGB can be performed to diagnose refractory VAs.

The parasternal block is an ultrasound-guided interfascial plane block that provides anesthesia of the medial quadrants of the breast. The original approach provided injections in the fascial plane between the pectoral major and external intercostal muscles. We observed that this technique might limit an adequate diffusion of the injectate due to the anatomical convexity of the ribs, which might hinder fascial hydrodissection. We suggest a modified approach by positioning the tip of the needle on the rib dome to reduce the local anesthetic volume and obtain a more homogeneous and longitudinal spread into the target fascial compartment.
