A 61-year-old woman was hospitalized for a chief complaint of sudden chest tightness with sweating for two hours. The chest tightness and sweating occurred suddenly and without remission after a morning stool. Electrocardiography showed a complete atrioventricular （AV） block and arc-like elevation of the ST-segment in leads Ⅱ, Ⅲ, AVF, V7-V9, and V3R-V5R, at about 0.05-0. 15 mV. After being administered 1 mg of atropine in the emergency room （ER）, the patient was admitted to the cardiology department. The patient had been found in a cyanotic state two years previously, but did not receive any treatment; she was diagnosed with a transient ischemic attack （TIA） 1.5 years previously because of limb dyskinesia accompanied by slurred speech.

Isolated right ventricular noncompaction caused recurrent pulmonary embolism

Journal of Geriatric Cardiology 2018年第5期15卷 382-386页

Clinically, pulmonary embolism （PE） mostly comes from the lower extremity deep vein system, but if such pa- tients have no evidence of deep venous thrombosis （DVT）, other sources of emboli should be considered. It is very rare that embolus comes from the right heart system （in situ thrombosis）, Isolated fight ventricular noncompaction （iRVNC） can cause PE, but it has not been reported so far. Ventricular noncompaction （VNC） is an unusual cause of cardiomyopathy.

Laparoscopic splenectomy:the latest technical evaluation

AIM: To introduce our latest innovation on technical manipulation of laparoscopic ***: Under general anesthesia and carbon dioxide (CO2) pneumoperitoneum, 86 cases of laparoscopic splenectomy (LS) were performed. The patients were placed in three different operative positions: 7 cases in the lithotomic position, 31 cases in the right recumbent position and 48cases in the right lateral position. An ultrasonic scissors was used to dissect the pancreaticosplenic ligament, the splenocolicum ligament, lienorenal ligament and the lienophrenic ligament, respectively. Lastly, the gastrosplenic ligament and short gastric vessels were dissected. The splenic artery and vein were resected at splenic hilum with EndoGIA. The impact of different operative positions, spleen size and other events during the operation were ***: The laparoscopic splenectomy was successfully performed on all 86 patients from August 1997 to August 2002. No operative complications, such as peritoneal cavity infection, massive bleeding after operation and adjacent organs injured were observed. There was no death related to the operation. The study showed that different operative positions could significantly influence the manipulation of LS. The right lateral position had more advantages than the lithotomic position and the right recumbent position in ***: Most cases of LS could be accomplishedsuccessfully when patients are placed in the right lateral position. The right lateral position has more advantages than the conventional supine approach by providing a more direct view of the splenic hilum as well as other important anatomies. Regardless of operation positions, the major axis of spleen exceeding 15 cm by B-ultrasound in vitro will surely increase the difficulties of LS and therefore prolong the duration of operation. LS is a safe and feasible modality for splenectomy.
