Nutcracker syndrome can cause disabling chronic pain requiring surgical intervention. At present, data describing a straightforward management approach are lacking. Transposition of the left gonadal vein is one of the surgical therapeutic alternatives. The aim of the present study was to describe our clinical results with gonadal vein transposition.

All 11 patients from three centers who had undergone left gonadal vein transposition for nutcracker syndrome from 2016 to 2019 were retrospectively included. The surgical cases were mainly selected according to the morphologic criteria of the left gonadal vein. The diameter and length dictated the type of approach (laparotomy or retroperitoneal) and the transposition level. A minimally invasive retroperitoneal approach was preferred. ALK inhibitor Pain was assessed using a numeric rating scale.

We included 11 patients (10 women) with a median age of 35years (range, 25-69). Preoperative computed tomography angiography showed anterior nutcracker syndrome in 10 patients (91%uropathic pain was noted, with a median score of 3.5 (range, 1.0-6.0) in seven patients (64%). Two late complications (18%) were observed one case of thrombosis and one case of anastomotic stenosis. The hematuria had disappeared in all patients who had presented with it initially.

Left gonadal vein transposition can be proposed as a first approach if the diameter of the left gonadal vein is sufficient to perform the anastomosis. It is an easily achievable, minimally invasive alternative that achieves satisfactory results without the use of foreign material.

Vascular malformations arise from defects in the morphologic development of the vascular system and can have an impact on quality of life and/or lead to severe complications. To date, vascular malformations are frequently managed by invasive techniques, after which recurrence is common. Sirolimus, a downstream inhibitor of the phosphatidylinositol 3 kinase/AKT pathway and best known for its immunosuppressive effect, has been used off-label for lesions for which approved therapies were associated with unsatisfactory results or recurrence. The aim of this study was to review the available data on the effect of sirolimus on the size and symptoms of different types of malformations and to summarize the main safety issues.

A literature search in Pubmed, Embase, Web of Science, and SCOPUS was performed. Case reports, case series, and clinical trials evaluating the effect of sirolimus in vascular malformations were eligible for this review. Fully terminated studies published between January 2010 and May 2019 rep Side effects were common (53%) but usually mild; mucositis and bone marrow suppression were the most common. Regrowth or recurrence of symptoms occurred in 49% of patients who discontinued treatment. Comparable effects were seen in our own patients.

This review shows that sirolimus is effective in decreasing the size and/or symptoms of particularly lymphatic malformations as well as VMs. Although common, side effects were usually mild. Nevertheless, clinical trials are needed to confirm the safety and effectivity of sirolimus and to identify the required serum levels and duration of treatment.

To examine a potential association between intranidal microhemodynamics and rupture using a phase-contrast magnetic resonance angiography (PCMRA)-based flow quantification technique in arteriovenous malformations (AVMs).

We retrospectively collected data on 30 consecutive patients with AVMs (23 unruptured and 7 ruptured). Based on PCMRA data, maximal (V
) and mean (V
) intranidal velocities were calculated. Logistic regression analysis was performed to assess factors associated with previous AVM rupture.

All ruptures occurred within 6 months before PCMRA. The mean nidus volume was 4.7 mL. Eleven patients (37%) had deep draining vein(s), and 6 patients (20%) had a deep-seated nidus. The mean ± standard deviation V
and V
were 9.6 ± 2.8 cm/second and 66.7 ± 26.2 cm/second, respectively. The logistic regression analyses revealed that higher V
(P= 0.075, unit odds ratio [OR]= 1.05, 95% confidence interval [95% CI]= 1.00-1.10) was significantly associated with prior hemorrhage. The receiver-operating curve analyses demonstrated that a V
of 10.8 cm/second (area under the curve= 0.671) and V
of 90.2 cm/second (area under the curve= 0.764) maximized the Youden Index. A V
> 90 cm/second was significantly associated with AVM rupture both in the univariate (P= 0.025, OR= 9.0, 95% CI=1.3-61.1) and multivariate (P= 0.008, OR= 51.7, 95% CI= 2.8-968.3) analyses.

Presence of faster velocities in intranidal vessels may suggest aberrant microhemodynamics and thus be associated with AVM rupture. PCMRA-based velocimetry seems to be a promising tool to predict future AVM rupture.

For aSAH patients with external ventricular drainage (EVD) because of hydrocephalus, the consensus on application of CSF drainage from the lumbar cistern is mixed owing to concerns about its safety and questionable effectiveness. This study evaluated the additional effectiveness of CSF drainage from the lumbar cistern in aSAH patients with EVD.

This was a retrospective and observational study of adult patients with aSAH who were admitted to the intensive care unit at the Wuhan Union Hospital between June 2018 and June 2019. Three aSAH patients with EVD and serial lumbar punctures (LPs) were selected for comparison of CSF components. Four more aSAH patients who underwent divergent CSF drainage were selected to profile the additional effectiveness of lumbar cistern drainage in aSAH patients with EVD.

Cases 1-3 with EVD and serial LPs showed dramatically higher red blood cell (RBC) and leukocyte counts with steeper changing curve in the lumbar cistern CSF than in the ventricle CSF. Case 5 had EVD alone and showed a slower clearing rate of blood clot in subarachnoid space compared with case 1.
