AbstractAzygos venous system drains the venous blood from thoracic wall. Knowledge of variations of its course and tributaries is important to cardiothoracic surgeons, radiologists and orthopedic surgeons. We observed the following variations in the azygos veins. Both azygos and hemiazygos veins were formed by union of lumbar azygos and subcostal veins of corresponding sides. The ascending lumbar vein did not drain into the azygos system. The hemiazygos vein had a larger diameter than the lower part of azygos vein and it joined azygos vein at the level of seventh thoracic vertebra. Accessory hemiazygos vein was totally absent. The azygos vein received 4th to 11th right posterior intercostal veins and also received 3rd to 6th left posterior intercostal veins. Hemiazygos vein received 7th to 11th left posterior intercostal veins.

AbstractHemiazygos vein and Accessory hemiazygos vein lie on the left side in the posterior mediastinum of thorax and are the counterpart of azygos vein on right side. During routine cadaveric dissection of thoracic region in an adult male, we found an abnormal venous channel which was single and was lying on the left side of the vertebral column. It received tributaries from superior intercostal vein and posterior intercostal veins. We found this abnormal venous channel draining directly into left brachiocephalic vein in contrast to its usual drainage into azygos vein. Hence this can be considered as abnormal venous channel and variant of hemiazygos vein and accessory hemiazygos vein. The azygos and hemiazygos venous system is commonly encountered during surgical intervention performed on posterior thoracic wall. This case report provides a new data of potential clinical significance.

Communicating Vein

Introduction: Aneurysm of the communicating vein between the left renal vein and left ascending lumbar vein is extremely rare with only anecdotal reported cases. Unless detected and recognized promptly, this rare condition may give rise to severe bleeding in patients undergoing retroperitoneal surgery. It may also closely mimic enlarged retroperitoneal lymph nodes, paragangliomas, adrenal masses, or renal artery aneurysms. Case report: In this case study, we reported the imaging findings of this rare entity which was falsely diagnosed as enlarged retroperitoneal lymph node in an outside medical center, reported as to be consistent with metastatic disease, in a patient with newly diagnosed testicular cancer. Conclusion: The aneurysm of the communicating vein should be considered in the differential diagnosis in patients with testicular cancer and other disease processes where lymph nodes are commonly affected.

Hemiazygos Vein

Introduction The azygos system of veins (ASV) is a very variable structure characterized as a communication between the inferior and superior vena cava, having the azygos vein (AV), the hemiazygos vein (HV), and the accessory hemiazygos vein (HAV) as its main components, which are responsible for the mediastinal viscera and for the thoracoabdominal wall drainage. The aim of the present study is to report an anatomical variation found in a male cadaver at the Laboratory of Anatomy of the University Center of UNIFACISA, Campina Grande, PB, Brazil. Case Report In the posterior mediastinum, the union of the HV, of the HAV, and of the 8th left posterior intercostal vein formed a common trunk at the level of the left 8th intercostal space, crossing the mediastinum posterior to the aorta artery, ending up in the AV, in the right hemithorax. Conclusion The study of the anatomical variations of the ASV is important and will provide knowledge for physicians not to confuse them with pathological processes in imaging exams. Moreover, it can provide safety in surgical approaches of the thorax.

ABSTRACT Introduction The azygos venous system has developed from the postcardinal veins of the embryo, and small parts persist only at the commencement of the azygos vein. Complex embryological development of these veins is a major cause for many possible variations of the azygos system. Materials and methods The present study was done in the Department of Anatomy, Government Medical College, Amritsar, on a male cadaver aged about 50 years. The thoracic cavity was opened to dissect the azygos system of veins. Results The system showed the persistent cranial part of the posterior cardinal vein. This led to the formation of a well-developed venous channel on the left side of the aortic arch and the thoracic aorta. This channel drained the 2nd to 10th left posterior intercostal veins and drained itself into the left brachiocephalic vein (LBV) after crossing the arch of aorta vertically on its right. There was no transvertebral communication between this channel and azygos vein on the right side. The hemiazygos vein (HAV) on the left side was normally formed and immediately drained into the azygos vein by turning to the left. The azygos vein on the right side was also normal. Conclusion The presence of such persistent embryological remnant, its position, and approximation to the structures near the arch of aorta should be taken into account to avoid radiological misdiagnosis and surgical complications.

Osteomyelitis of maxillofacial skeleton is common in developing countries such as India. This case report describes successful surgical treatment of chronic suppurative osteomyelitis {CSO} of the mandible of a 35yr old female. The precipitating factor was thought to be eventful extraction in the {left } posterior body at the inferior border of mandible. Methods: Presurgical course of antibiotics ( Amoxycillin and metronidazole for 7 days and later followed by doxycycline for 1 month).Surgical debridement of the affected bone and reinforcing it with reconstruction plate using AO principles was done . Patient was kept on a high nutrient diet consisting of proteins. Conclusion: The case report demonstrates the typical features of CSO . The combination of the antibiotics therapy and surgical debridement was successful in the treatment of chronic suppurative osteomylitis.

Abstract Direct hepatic veins-to-hemiazygos connection offers the balanced distribution of hepatic venous blood to both lungs, not requiring anticoagulation. We report a 13-year follow-up after this type of off-pump Fontan completion. Patient’s hepatic veins-to-hemiazygos confluence increased with growth to allow for unobstructed flow. This unique technique can be recommended in heterotaxy patients, if atrial hepatic venous drainage and hemiazygos vein are in close proximity.
