Effect of computed tomographic venography on donor selection in submandibular gland transplantation in patients with severe dry eye

Abstract OBJECTIVE AND IMPORTANCE Venous obstruction has been postulated as a cause of increased intracranial pressure, but it has been documented rarely. We present a case of obstruction of the torcula by a slow-growing epidermoid. The tumor caused increased intracranial pressure, which was relieved when it was excised. In addition, the torcular epidermoid is associated with a bifid straight sinus. CLINICAL PRESENTATION A 35-year-old man presented with a headache and a lump on the back of the head. Physical examination revealed a firm, bony lesion approximately 4 × 4 cm in size. Lumbar puncture demonstrated an intraspinal pressure of 39 cm H2O. Neuroradiological studies revealed an epidermoid that compressed and almost completely occluded the torcula. INTERVENTION After the tumor was resected, the intraspinal pressure decreased to 19 cm H2O and remained stable 6 months later. CONCLUSION Pure venous obstruction causes increased intracranial pressure. Removal of the obstruction relieves the intracranial hypertension. In addition, computed tomographic venography is a safe and easy method of documenting torcular anatomy, and it was useful in the follow-up of this patient. Computed tomographic venography can demonstrate a double straight sinus, which is a congenital variant that may be associated with the epidermoid.

Pelvic Congestion

Pelvic congestion syndrome is one of many causes of chronic pelvic pain. It is generally accepted that this is attributable to ovarian and pelvic vein incompetence which may result in varices in the lower limb leading to presentation in varicose vein clinics. However, far more patients have pelvic varices associated with varicose veins in the lower limb than have pelvic congestion syndrome. Magnetic resonance imaging and computed tomographic venography are usually used in the diagnosis of this condition and criteria have been established to identify pelvic varices. Many different treatments have been used to manage the symptoms of pelvic congestion. Hysterectomy combined with oophrectomy open surgical ligation of ovarian veins and laparoscopic vein ligation have been used in the past. The most common treatments used currently involve embolization of pelvic and ovarian veins. The results of this treatment have been published in a limited number of clinical series, usually with fairly short follow-up periods. These treatments may be complicated by migration of embolization of coils used to occlude veins. The longest duration of follow-up currently reported is five years. Limited clinical evidence supports the use of embolotherapy in the management of pelvic congestion syndrome.

Experienced Pain

Objectives: The aim of this study is to evaluate the factors affecting subjective symptoms, especially pain and swelling in submandibular gland sialolithiasis. Methods: We analyzed the computed tomographic (CT) findings of submandibular gland sialolithiasis (stone size/location/ number) and assessed white blood cell (WBC) (neutrophil/absolute neutrophil count) and erythrocyte sedimentation rate (ESR) to elucidate the correlation with subjective symptoms, especially swelling and pain. Results: Of the 82 patients, 45had a solitary stone. Thirty seven patients experienced pain and 73 patients had swelling. The number, location and size of the calculi were not associated with symptoms, especially pain and swelling. From logistic regression analysis, WBC (p=0.048) and the percentage of neutrophils (p=0.027) were associated with the presence of pain, but not swelling. Conclusion: To our knowledge, this is the first study to observe that both the location and size of stone are not significantly related to subjective symptoms, especially pain and swelling in submandibular gland sialolithiasis.
