Usefulness of Oral Xa Inhibitor for Management of Ischemic Stroke Associated with Thrombosis in the Pulmonary Vein Stump after Lung Resection.

OBJECTIVES: Brain infarction is a critical complication after lung resection using video-assisted thoracoscopic surgery. Recent reports have described its association with thrombosis in the pulmonary vein (PV) stump. However, the optimal management of this complication remains controversial. We describe serial 3 cases of brain infarctions associated with thrombosis in the PV stumps, which were successfully treated with the oral Xa inhibitor rivaroxaban. METHODS AND RESULTS: We retrospectively reviewed medical records of 3 patients. The first case was a 72-year-old man who underwent left upper lobectomy for treatment of lung adenocarcinoma. The second case was a 55-year-old man who underwent right lower segmentectomy for treatment of metastatic tumor from Barrett's esophageal carcinoma. The third case was a 73-year-old man who underwent left upper lobectomy for treatment of metastatic tumor from colon adenocarcinoma. In the first case, a large cerebellar infarction was developed and a decompressive craniotomy was performed on postoperative day 4. In the second and the third case, cerebral infarctions in the territories of right middle cerebral arteries occurred on postoperative day 2. In all cases, contrast-enhanced computed tomography demonstrated the thrombi in the stumps of the PVs. They were treated with oral administration of rivaroxaban without adverse effect, and the thrombi in the PVs disappeared within 1 month. DISCUSSION: Blood flow stasis in the long PV stump after lung resection might contribute to thrombosis development. Oral Xa inhibitor rivaroxaban appeared to be safe and useful for the management of ischemic stroke associated with PV thrombosis after lung resection.

A 10-year experience of totally extraperitoneal endoscopic repair for adult inguinal hernia.

PURPOSE: Laparoscopic surgery is fast becoming the treatment of choice for inguinal hernia. By reviewing our 10-year experience of performing totally extraperitoneal repair (TEP), we sought to establish its clinical significance in the treatment of adult inguinal hernia. METHODS: We reviewed retrospectively the clinical records of patients who underwent TEP for adult inguinal hernia between January 2003 and December 2012. RESULTS: None of the 303 patients with adult primary or recurrent inguinal hernia in our study needed TEP converted to other procedures or suffered serious complications during the procedure. A significant difference was noted in the operation time between direct (n = 32) vs indirect (n = 128) hernias in the primary unilateral inguinal hernia group (91 ± 27 vs 80 ± 32 min, p = 0.033) and between direct/direct (n = 31) vs indirect/indirect (n = 24) hernias (136 ± 58 vs 89 ± 24 min, p = 0.01) in the primary bilateral inguinal hernia group. The only postoperative complications recorded were four cases of hernia recurrence (1.3 %) and one case of chronic pain (0.3 %). CONCLUSIONS: The results obtained for TEP over 10 years support this as a promising procedure for the treatment of adult inguinal hernia.
