Successful Endovascular Treatment of a Spontaneous Rupture of the Ascending Lumbar Vein: A Case Report

Although there have been a few case reports of spontaneous rupture of pelvic veins, such as the iliac vein, to date, there have been no reports of spontaneous rupture of the ascending lumbar vein. Here, we report a case of spontaneous rupture of the ascending lumbar vein for the first time. A 66-year-old woman visited the emergency department due to the swelling of the left lower limb for 2 hours. After admission, the patient developed symptoms of pain in the left lumbar region, as well as symptoms of shock, such as increased heart rate and decreased blood pressure. During emergency venography, it was found that the ascending lumbar vein was ruptured, which was accompanied by the compression and occlusion of the iliac vein (May-Thurner syndrome). During the endovascular surgical treatment, a covered stent was placed in the iliac vein, and the occluded common iliac vein was treated with a bare stent. Immediately after the surgical procedure, the patient’s abdominal computed tomography examination showed the formation of a large retroperitoneal haematoma, and continuous routine blood parameter monitoring showed that haemoglobin was stable. Postoperative recovery was uneventful, and the patient was discharged on the ninth postoperative day.

Aneurysm of the communicating vein between the left renal vein and left ascending lumbar vein mimicking a retroperitoneal lymphadenopathy: A case report

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.

Multiple variations of azygos system of veins: a case report

Azygos 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.

Anatomy Revisited: Hemodialysis Catheter Malposition in the Left Ascending Lumbar Vein

In selected cases, cuffed tunneled catheters via the iliac vein are implanted as a last resort access for hemodialysis. To monitor the correct position, sonography of the inferior vena cava (IVC) is sufficient in most cases. Position control using an X-ray of the abdomen is not routinely recommended when femoral catheters are implanted. In this report, we describe the case of a 59-year-old patient on chronic hemodialysis due to granulomatosis with polyangiitis and complex shunt history with multiple shunt occlusions and revisions. The implantation of an iliac-cuffed tunneled catheter led to complications because the catheter was malpositioned into the left ascending lumbar vein (ALV). It is important to be aware of potential incorrect positioning of dialysis catheters into the ALV. Due to the anatomical relation to the IVC, this happens more frequently on the left side than on the right side. In case of doubt, the correct placement of large-bore catheters via iliac access route should be verified by means of appropriate imaging before hemodialysis is performed.
