Retrieval of intravascular iatrogenic foreign bodies using a nonsurgical technique

A retrospective evaluation of polyurethane, long-stay, peripheral venous cannulae in dogs undergoing radiotherapy

OBJECTIVES

The aim of this retrospective study was to review placement duration and associated complications of long-stay, peripheral venous cannulae in dogs undergoing a radiotherapy protocol. Factors affecting duration of stay of the cannulae were evaluated.

METHODS

The records of patients which had a single-lumen, 16-gauge, 16-cm polyurethane cannulae inserted into a peripheral vein between 2010 and 2014 were reviewed.

RESULTS

Forty-one cannulae were placed in 41 patients. Median duration of cannula stay was 14 days (range 2 to 26). In 14 cases (~34%) the cannula was removed at the end of the radiotherapy course. In 13 (~32%) cases, cannula-related complications resulted in premature removal. Use of steroids and antibiotics appeared to be associated with a longer median duration of stay.

CLINICAL SIGNIFICANCE

No life-threatening complications were encountered. Indwelling, polyurethane, saphenous cannulae were an effective and safe way to maintain venous access in this group of patients. Prednisolone and antibiotics were typically commenced for acute radiation side effects -midway through the protocol; therefore their association with length of stay may not be a direct result of their administration.

A Rare Complication of Varicose Vein Surgery

Design:

Case report.

Setting:

University Hospital in the Czech Republic.

Patients:

Patient undergoing surgery for primary varicose veins.

Interventions:

The patient underwent attempted long saphenous vein stripping by passing a flexible stripper from ankle to groin. The stripper fractured at its upper end and a fragment of stripper became lodged in the internal iliac vein in the pelvis. This was removed at laparotomy. The patient made an uncomplicated recovery.

Conclusion:

Major complications of varicose vein surgery are rare. This unusual problem was probably caused by material fatigue in the stripper, leading to fracture near the upper end of the stripper.
