azygos anterior cerebral artery (ACA) is type I variation of ACA with a reported incidence of azygos ACA is between 13% and 71%(2,3)It is often associated with other central nervous system (CNS) malformations like agenesis of corpus callosum, hydranencephaly and other vascular malformations[4].

We present a rare case associating inferior vena cava’s (IVC) complex variations. Anatomical, embryological and clinical aspects are discussed. Duplication’s discovery was fortuitous during an abdominal ultrasound and was confirmed by the CT scan. The latter also highlighted azygos continuation, retro aortic renal vein and an iliac venous anomaly. These variants are important to know in order to be able to differentiate them from lymphadenopathy, para-vertebral masses, and aortic pathologies. It is necessary to report them before any retroperitoneal surgery or interventional vascular procedure.

提要本文报告177例采用远脾肾分流术和门奇断流两种术式治疗门脉高压症的分析比较。两组在肝功能分级的选择上差异无显著意义。同一手术组肝功能分级与生存时间之间差异无显著意义。分流组与断流组1、3、5、10年生存率分别为98.63%、94.31%、90.87%、81.43%和94.78%、90.21%、86.28%、79.38%。手术死亡率分别为5.5%和4.7%,再出血率分别为12.3%和13.5%。脑病发病率为0%,两组疗效均较满意,分流组生存率优于断流组。

World Journal of Gastrointestinal Endoscopy 2013年第9期5卷 450-454页

Pseudoachalasia is a rare secondary achalasia, which accounts for only a small subgroup of patients. We describe a 77-year-old woman with recent onset of dysphagia and typical esophageal manometric findings of achalasia. Moreover, esophageal manometric findings of vascular compression at 36 cm from the nose were associated with dysphagia. An upper endoscopy showed the absence of lesions both in the esophagus and gastro-esophageal junction, whilst a 15-mm ulcer on the gastric angulus was detected. The gastric ulcer resulted in being a diffuse signet ring cell carcinoma at histology, suggesting pseudoachalasia. An abdominal computed tomography scan showed an irregular concentric thickening of the gastro-esophageal junction wall extending for 7 cm and a dilated ascending thoracic aorta with no presence of the inferior vena cava, with an enlarged azygos as the source of vascular compression of esophagus. Moreover, cardia involvement from diffuse signet ring cell carcinoma of the gastric angulus was also recognized as the cause of dysphagia. The cancer was not suitable for a surgical approach in an old patient with cardiovascular comorbidities and support therapy was started. In our ambulatory series, pseudoachalasia was eventually diagnosed in 4.7% of 234 consecutive patients with esophageal manometric finding suggestive of achalasia. We also reviewed cases in the literature and aimed to evaluate the reported causes of pseudoachalasia.
