Double level arterial injury with neuropraxia following anterior shoulder dislocation

Vascular and nervous complications are rare after shoulder dislocation. We report the case of a double level arterial injury with neuropraxia following anterior shoulder dislocation that was diagnosed by MultiDetector-row Computed Tomographic (MDCT) angiography and treated by surgical bypass graft and embolectomy. Our case is original, not only because of the rarity of these complications, but also because of the thromboembolism of brachial artery which could be undiagnosed and could compromise prognosis.     

A case of sacral hydatid cyst

INTRODUCTION

Hydatid cyst of bone constitutes only 0.5-2% of all hydatidoses. The thoracic spine is the most common site of spinal hydatidoses. Primary hydatid cyst of the sacral spinal canal is rare.

PRESENTATION OF CASE

A 19-year-old man had cauda equina syndrome with pelvic pain 15 days ago, the pelvic radiography shows a lytic image depend on the left sacral wing. MRI showed an intra-pelvic cystic image invading the sacrum T1 hypointense and T2W hyperintense. The Hydatid serology was positive.Surgical treatment consisted of a wide drainage of hydatid cavity dug in the left sacral wing, and by which it communicated intra pelvic, with removal of the entire cyst by gentle aspiration, abundant rinsing with hypertonic saline, release and sacred roots encompassed in a puddle of fibrosis hydatid.The evolution was good with recovery of perineal sensation and anal tone. The sacroiliac joint was considered stable and did not require synthesis or reconstruction.

DISCUSSION

Hydatid cysts predominantly occur in liver and lungs. Involvement of other organs is uncommon. Neither surgery nor medical therapy is generally effective for bone, especially spinal hydatidosis. The initial treatment of choice is surgical excision for neural decompression and establishing diagnosis. Albendazole is the drug of choice against this disease, when suspected, presurgical use of Albendazole in Echinococcus infestations reduces risk of recurrence and/or facilitates surgery by reducing intracystic pressure.

CONCLUSION

A missed diagnosis of hydatid cyst could be devastating. Hence, hydatid cyst should be kept as a differential diagnosis, when encountered with a cystic lesion of sacrum. In addition, longterm follow-up is mandatory as recurrence is high despite use scolicidal agents.     

Deep Venous Thrombosis in Spine Surgery Patients: Incidence and Hematoma Formation

Deep venous thrombosis (DVT) is a significant health care problem; a variety of factors place spinal surgery patients at high risk for DVT. Our aim is to define the incidence of DVT occurrence in spite of prophylactic measures (mechanical and chemoprophylaxis), and the development of spinal epidural hematoma as a complication of chemoprophylaxis. In a single-center prospective study, 158 patients who underwent spinal surgical procedures were evaluated by clinical evaluation and lower limb Doppler ultrasonography imaging. Only one patient (0.6%) developed DVT; this patient was treated successfully without thrombus progression, with full recanalization. Three patients (1.8%) developed spinal epidural hematoma, but only one required surgical evacuation, and none sustained neurologic deficit. Careful evaluation for DVT risk on an individual basis and good prophylaxis helps to minimize the risk of DVT. The neurosurgeon is thus left to weigh the risks of postoperative hematoma formation against the benefits of protecting against DVT.     

Overall of kidney transplant recipients with a pretransplantation cancer history

No significant morbidity from recurrence cancer and no development of secondary type of cancers in pre‐existing malignancies. We must be careful about risk of rejection.     

Fortuitous discovery of isolated tuberculosis of the tenth and eleventh costotransverse joints: A case report

Involvement of posterior elements of the spine in spinal tuberculosis is rare. We report a case of a 56-year-old woman who presented with asymptomatic tuberculosis of the tenth and eleventh costotransverse joints. The latter was discovered with a CT scan made to look for a pulmonary embolism. Magnetic Resonance Imaging (MRI) showed liquid in the costotransverse joints with a paravertebral abscess. The patient was managed conservatively. Although rare, posterior tuberculosis of the spine should be known by spine surgeons. MRI is the key to the diagnosis. Conservative treatment is the standard treatment, and surgery is reserved for patients with neurological deficit.
