Complications encountered during arterial embolectomy with the Fogarty balloon catheter.

The Fogarty arterial embolectomy catheter, while indispensible in the armamentarium of the vascular surgeon, is not entirely benign instrument. A case is desribed in which the balloon was lost in its entirety from the catheter and immediately retrieved using a second identical instrument. A comprehensive survey of the literature reveals that a variety of arterial injuries have occurred during the use of the Fogarty catheter. Each of the major ones is discussed in depth. Amongst the most serious are arterial perforation and rupture occasionally followed by loss of the involved extremity. All previously reported complications following use of the Fogarty catheter are tabulated and reviewed. Additionally, a formal classification of these complications is proposed. Since the time of its introduction in 1963 the Fogarty ballon-tipped catheter has become an indispensible tool in the armamentarium of the vascular surgeon. Its use for arterial embolectomy has been responsible for the salvage of many thousands of limbs. Over the course of the past decade, however, a number of complications referable to this instrument have appeared in the literature. These include perforation of vessels, intimal disruption and foreign body embolization amongst others. To our knowledge, however, there has been only one reported case of a balloon having been lost intra-arterially in toto without obvious cause. It is the purpose of this paper to present the second such case where the balloon, which had separated entirely from the catheter during the course of an arterial embolectomy, was later retrieved by passage of a second Fogarty catheter. In addition, a comprehensive review of the literature is undertaken, and all arterial complications reported to date summarized and tabulated.

Carcinosarcoma of the esophagus: a case report and review of the literature.

A case of carcinosarcoma of the esophagus and a review of literature are presented. The pertinent clinical and pathological data are summarized. There have been 51 reported cases of which 31 underwent surgical resection of the lesion; there have been three five-year survivors. Although the cumulative experience with this malignancy is limited, it is apparent that the presentation and clinical course of this tumor is not substantially different from the more common squamous cell carcinoma. Therefore, the diagnostic and therapeutic management should not vary from that of any malignant esophageal lesion.
