RESUMO
Background: Microvascular decompression (MVD) of the trigeminal nerve is a well-accepted nondestructive procedure for trigeminal neuralgia. Usually, Teflon (PTFE) puff or felt graft techniques, which are most commonly used, are associated with arachnoiditis and recurrence among other complications. We use the "sleeve graft" technique using PTFE to separate the neurovascular conflict and here we describe our experience with the same in 376 cases. Objectives: To study the outcomes in 376 patients treated with sleeve graft technique for trigeminal neuralgia. Materials and Methods: For a period of 18 years, from 2002 to 2020, all cases of medically refractory trigeminal neuralgia were subjected to the "sleeve graft" technique for MVD. Pre- and post-operatively, pain score was given according to Barrow Neurological Institute pain intensity score. Cases were observed for any complications and pain relief in short and long-term follow-up. Results: In total, 376 cases of refractory primary trigeminal neuralgia cases, among which 198 patients underwent MVD with no prior intervention, 158 underwent MVD following percutaneous ablative procedure, 13 were "Revision MVD" previously done at other centers, and four were post gamma knife failure. There was no incidence of arachnoiditis or recurrence of symptoms. Further, 368 (97.8%) patients had complete recovery from symptoms while eight (2.2%) had partial recovery after 5 years of follow-up. Complications included hearing loss (n = 1), temporary hypoesthesia (n = 45), and permanent hypoesthesia (n = 7). Conclusion: "PTFE Sleeve Graft" technique to remove the neurovascular conflict in micro vascular decompression (MVD) for trigeminal neuralgia is a safe and effective technique that yields better results.

Craniopharyngiomas are the most commonly presented nonglial tumors in child patients. They cause significant morbidity and mortality, both before and after surgery. The most common immediate postsurgery complications are attributable to pituitary insufficiency. Neurovascular complications account for only 2.7 to 2.9% surgical cases, and usually involve the vessels of the Circle of Willis. Thrombosis or vasospasm of the vessels of posterior circulation is unheard of. Here, we are reporting a unique case of a child with craniopharyngioma who developed acute spontaneous basilar artery thrombosis and posterior circulation stroke 6 days after surgery.
RESUMO
Xanthogranulomatous pyelonephritis (XPN) is a rare form of chronic pyelonephritis, which is usually caused by calculous obstructive uropathy. We present a previously healthy 45-year-old housewife, who was admitted to The Dammam Central Hospital, Dammam, Saudi Arabia with left loin pain and increased frequency of micturition of four days duration. She also had icterus and features of disseminated intravascular coagulation. Abdominal ultrasound and computed tomography of the abdomen was suggestive of XPN. She responded well to treatment with antibiotics and nephrectomy. Histology of the resected kidney confirmed a diagnosis of XPN. Our case suggests that the diagnosis of XPN should be kept in mind when a middle-aged female patient presents with unilateral non-functioning hydronephrotic kidney, which is totally distorted, and has enhancing as well as non-enhancing regions on computed tomography.
