RESUMO
Totally implantable venous access ports (TIVAPs) are widely used for chemotherapy and other purposes in patients with cancer. Their convenience and safety make them ideal for long-term use. However, sometimes there are cases in which TIVAPs remain in the vessel following the completion of long-term chemotherapy and are difficult to remove due to the adhesion of the catheter to the vessel wall. In this study, we encountered a case in which a TIVAP catheter adhering to a blood vessel was fractured during removal and the catheter left in the vessel could not be retrieved by a snare because it had no free end. Finally, the catheter was successfully removed using a peel-away sheath. No complications or residual catheters were associated with the removal procedure.
RESUMO
A 90-year-old female presented with poor right groin wound healing due to lymphorrhea and infection following a surgical cutdown procedure for arterial revascularization. Although negative pressure wound therapy (NPWT) and inguinal lymphadenectomy were performed, infection and lymphorrhea did not heal. Lymphangiography via a right inguinal lymph node revealed lymphatic leakage in the wound. Intranodal glue embolization (IGE) was performed by injecting 0.6 mL of 33% n-butyl-2 cyanoacrylate (NBCA)-lipiodol mixture. Additionally, the presence of glue in an open wound was directly confirmed in this case. After embolization, lymphorrhea ceased, and the wound healed completely. No lymphorrhea recurrence or complications were observed for 6 months. This case suggests that IGE could be an effective treatment for groin lymphorrhea.
RESUMO
Purpose: Bone cement enhancement by percutaneous vertebroplasty (PVP) for the treatment of osteoporotic vertebral compression fractures remains unapproved, as it has not been fully evaluated in Japan. The current multicenter study was conducted in Japan to verify the safety and efficacy of PVP in patients with painful osteoporotic vertebral fractures. Material and Methods: In this retrospective study, we referred to previous studies to evaluate the non-inferiority of PVP to balloon kyphoplasty (BKP). We reviewed consecutive patient data from April 2017 to March 2018 from four institutions based on the medical records of the intervention. We statistically investigated the adverse events due to cement leakage or other factors associated with PVP, and new vertebral compression fractures after PVP were evaluated for safety, pain relief, and gait improvement. Results: This study included 485 patients; most of whom were in the middle- to oldest- age groups (mean age, 81.4 years). No serious adverse events were reported in patients available for safety evaluation (n = 485). Cement leakage and new vertebral compression fractures occurred in 35.7% and 18.6% (26.2%-38.4% and 8.9%-20.7%) of the patients undergoing PVP, respectively, both of which were also judged to be equivalent to those of BKP. The pain score improved in those undergoing PVP, and this improvement was maintained during a one-year follow-up. Of the 206 patients who had difficulty walking at baseline, 156 had restored walking at discharge. Conclusions: PVP was shown to be a safe and effective treatment, even in elderly patients with painful osteoporotic vertebral fractures.
RESUMO
OBJECTIVES: Isolated superior mesenteric arterial dissection (ISMAD) is an uncommon type of arterial dissection and treated with surgery, stenting, or conservative management. This study aimed to evaluate the criteria for conservative therapy for ISMAD patients based on imaging findings. METHODS: Eighteen consecutive ISMAD patients without peritoneal irritation at onset were retrospectively studied. The decision to perform stenting was based on the emergence of peritoneal irritation, aneurysm, or mesenteric ischemia. Clinical manifestations, follow-up contrast-enhanced computed tomography (CECT) findings, and patient outcome were evaluated. RESULTS: Most patients (16, 89%) were successfully treated conservatively; two patients (11%) required endovascular stenting because of an aneurysm or ulcer-like projection (ULP) sign. The median duration of fasting and hospital stays was 3 (range, 1-8) and 9 (range, 4-34) days, respectively. On CECT, the median distance from the superior mesenteric artery (SMA) origin to the entry site was 12 mm (range, 5-35 mm), and the median length of dissection was 87.5 mm (range, 20-150 mm). Among 16 patients treated conservatively, serial imaging was obtained in 11 patients (69%), and disappearance of the dissection within 4 months occurred in five patients. Two patients treated with endovascular stent underwent follow-up CECT 1 year after onset, and there were no complications. CONCLUSIONS: ISMAD patients without peritoneal irritation can be treated conservatively if there are no signs of an aneurysm, ULP, or mesenteric ischemia. When an aneurysm or ULP sign exists, endovascular stenting was able to preserve SMA blood flow with the improvement of the dissection.
