Analysis of the contribution of 129 candidate genes to thoracic aortic aneurysm or dissection of a mixed cohort of sporadic and familial cases in South China.

Am J Transl Res 2021 15;13(5):4281-4295. Epub 2021 May 15.

Department of Cardiovascular Surgery, Guangdong Provincial People's Hospital, School of Medicine, South China University of Technology Guangzhou, China.

LVIS-within-enterprise double-stent procedure without coiling beneficial as treatment of unruptured vertebral artery dissecting aneurysms.

Interv Neuroradiol 2021 Jun 18:15910199211025109. Epub 2021 Jun 18.

Department of Neurosurgery & Radiology, Veterans Health Service Medical Center, Seoul, Korea.

Stenting of vertebral artery dissecting aneurysms (VADAs) may promote mural apposition of intimal flaps, preserving the patency of injured vessels. Moreover, stent deployment may serve to alter intra-aneurysm flow, inducing saccular thrombus formation, neointimal development, and remodeling of injured vessels. Although an overlapping multistent strategy with coiling has proven successful in this setting, yielding good anatomic and clinical outcomes, coiling may be technically infeasible in some VADAs with unfavorably configured circumferential elevations.

[A Case of Advanced Gastric Cancer with Para-Aortic Lymph Node Metastasis with Long-Term Survival by Chemotherapy and Surgery].

Gan To Kagaku Ryoho 2021 Jun;48(6):825-827

Dept. of Surgery, Saitama Cooperative Hospital.

Chemotherapy is the standard treatment for unresectable gastric cancer, but there is no clear evidence of therapeutic lymphadenectomy in conversion surgery after the tumor shrinks or the combined effect of perioperative chemotherapy. A 63-year-old man was diagnosed with advanced gastric cancer by upper gastrointestinal endoscopy; computed tomography (CT)showed swelling of the gastric regional lymph nodes, abdominal para-aortic lymph nodes, and left supraclavicular lymph node. After 4 courses of combination therapy with S-1 and cisplatin(SP therapy), CT showed that the left supraclavicular lymph node disappeared and the para-aortic lymph node was reduced. Read More
