Unexpected difficulty in ventilating the lungs after tracheal intubation -A case report-

We experienced difficulty in ventilating the lungs of a patient after tracheal intubation. After intubation, an insufficient amount of tidal volume (VT) was delivered to the patient and the fiberoptic bronchoscopic examination identified partial abutment of the endotracheal tube (ETT) orifice against the tracheal wall. After various attempts to correctly place the ETT, a double-lumen endotracheal tube was placed to achieve a sufficient VT. It is important to notice that even an appropriately placed ETT may get obstructed due to the left sided bevel at its tip

Variations of the Superficial Brachial Artery in Korean Cadavers

The superficial brachial artery (SBA), a branch of the axillary artery, is one of the most common arterial variations in this area. While it is more vulnerable to accidental arterial injection or injury, it could be useful for the nourishment of a medial arm skin free flap. To analyze the relationship between the SBA of axillary origin and segmental variation of the axillary artery, we dissected 304 arms of Korean cadavers. We found an SBA of axillary origin in 12.2% of cadaveric arms. Unilateral occurrence was detected in 16 cadavers and bilateral in 10. SBAs gave rise to radial and ulnar arteries in the cubital fossa (8.9%), continued in the forearm as the radial artery (2.3%), or ended in the upper arm (1.0%). The SBA ended as ulnar artery was not found in any of the cadavers. The bifurcation of the SBA into the radial and ulnar arteries, presence of an SBA that ends in the upper arm, and the lack of continuation as the ulnar artery are characteristics of SBAs in Korean cadavers

Pulmonary thromboembolism after tourniquet inflation under spinal anesthesia -A case report-

Pulmonary thromboembolism is one of the most important causes of morbidity and mortality in patients undergoing lower extremity orthopedic surgery. Early diagnosis and appropriate management are important clinical challenges. In this case, massive pulmonary embolism causing sudden cardiac arrest was attributed to use of tourniquet inflation during lower extremity orthopedic surgery. Resuscitation procedures were initiated and transesophageal echocardiography revealed pulmonary thromboembolism. Patients with high suspicion for the presence of deep vein thrombus must be monitored thoroughly during limb exsanguinations

A Case of Disseminated and Fulminant Plasmacytomas That Developed during Bortezomib Treatment

Multiple myeloma is an incurable and slow growing plasma cell neoplasm. The introduction of new drugs has increased the number of treatment options. Bortezomib, the first-in-class proteasome inhibitor, has been shown to have a significant antitumor activity in the treatment of relapse/refractory patients with multiple myeloma. Additionally, plasmacytomas have shown significant response to bortezomib. In this case report, we describe a patient who developed disseminated and fulminant extramedullary plasmacytomas during combination chemotherapy treatment with bortezomib within a short period, after having shown clinical improvement
